This study aimed to evaluate the efficacy of platelet rich plasma (PRP) and advanced platelet rich fibrin (A-PRF) on regeneration of induced tibial bone defects in dogs. A 7mm circular tibial defect and 10mm depth was performed at the proximal extremity of the right and left tibiae of 12 adult apparently healthy male mongrel dogs. The animals were divided into control group, PRP group and A-PRF group. Regeneration of the tibial defect was evaluated by radiographic, computed tomography (CT), gross and histopathological examination at 6 and 12 weeks postoperatively (PO). At 6 weeks PO, the tibial defect was partially filled with fibrous tissue and appeared radiolucent radiographically in the control group and were partially closed with newly formed bone and appeared more radiopaque in PRP group than the control group while tibial defect was completely closed with newly formed bone and appeared more radiopaque in A-PRF group than the PRP group. At 12 weeks PO, the tibial defect was partially filled with newly formed bone and appear more radiopaque in control group and completely closed with newly formed bone and appeared radiopaque in PRP group. Interestingly, the tibial defect of the A-PRF group was completely closed with newly formed bone and cannot be differentiated from the neighboring normal bone tissue. In conclusion, using of PRP and A-PRF improved bone healing. However, A-PRF improved early regenerative ability of the tibial defect in comparison to PRP.

This research aims to investigate the fracture healing effects caused by thyroidectomy. The experiment involved sixteen matured male rabbits of local breed which divided into 2 equal groups (control and treated). Rabbits anesthetized by premedicated atropine sulphate, then 15 minutes later, a mixture of Xylazine Ketamine was used. The control group rabbits were induced with mid-shafted femoral fracture, with that, the fixation by intramedullary pinning was considered Meanwhile, the treated group rabbits were induced with same method mentioned above, but fracture were fixed after thyroidectomy and measurement of thyroxin a week after thyroidectomy. Results which were obtained from the clinic revealed signs of severe inflammatory reaction in control group which were higher comparing to treated group. These sings were disappeared within 4-5 days in treated group, while, it took 5-6 days in control animals. Also, radiological results of 2 groups showed that a periosteal reaction was observed towards the end of the 2nd week in the control group, whereas, the treated group showed its reaction at the end of fourth week, there was an invisible fracture line for both control and treated groups at the end of fourth and seventh week, respectively. In addition, bony bridge in the control groups became remodeled into a lamellar bone earlier than treated group. The results of measuring thyroxin hormone before and after the thyroidectomy confirmed the essential role of this hormone in fracture healing. To conclude that the fracture healing maturity was greater in control group than in treated group.

The study was designed to determine the role of adding hyaluronic acid as a supportive filling material to improve grafting process of experimentally defective tibial bone in dog model. Eighteen local breed dogs of both sexes weighted 18± 0.4 kg and aged (12± 0.6Months) were randomly allocated in two equal groups. In the first group, twelve dogs underwent experimental tibial bone defect (2.5×0.7 cm ) and replaced with deprotenized lamb ribs. The second group were treated as that for the first, but supported by adding 1% hyaluronic acid, to their grafts. The bone in both groups was firmly fixed by cerclage wire. All dogs were; followed-up clinically, radiologically and macroscopically at (14, 30 and 60 days after the intervention. In all study dogs the systemic infections, signs of seromas, hematoma and sever lameness were not developed along the period of the study . Grossly, dogs in the second group at 60 days showed an increase in the size of the filler of bone at the edges and in the mid of the defect, improvement and acceleration in the bone healing, and formation of bone bridges compared to the first group. Radiological finding exhibited complete healing of the fixated bone segment with the surrounding area; however, some cortical irregularities denoted chronic periosteal reaction and callus formation in the treatment with hyaluronic acid. In conclusion, the study indicated that hyaluronic acid with xenograft materials exhibited remarkable beneficial effects on improvement of the tibial bone defect augmentation

A challenge to the orthopedic surgeons in veterinary and human fields is the treatment of delayed union, malunion and nonunion. Apart from renovation of arrangement and constant fixation, in many cases, adjunctive measures such as bone-grafting or the use of bone-graft substitutes, are of dominant significance. In general bone-graft materials comprise one or more components: an osteoconductive matrix, which acts as a scaffold to new bone growth; osteoinductive proteins, backing the mitogenesis of indistinguishable cells; and osteogenic cells, which can form bone in the proper environment. Our review focuses on the currently existing bone graft and graft substitutes for the novel therapeutic approaches in the clinical situation of orthopedic surgery. This review is based on an extensive literature search of different composite scaffolds developed as bone regenerative therapies. The settlement and drawbacks of different composite scaffold developed techniques, the properties of generally used ceramics and polymers, and the properties of presently investigated synthetic composite grafts. To follow, an exhaustive review of in vivo models is used to test composite scaffolds in segmental bone defects (SBDs) to serve as a guide to design suitable translational studies and to recognize the challenges that require to be overcome in scaffold design for successful transformation. This includes the formative of the anatomical position within the animals, selecting the accurate study period, and an overview of scaffold presentation evaluation.

In the present study, the effect of autogenous peritoneum graft (PG) with platelet rich fibrin (PRF) was evaluated on intestinal anastomosis healing in dogs. Eighteen local breed adult dogs were anesthetized then jejunal intestinal resection and anastomosis were created on all animals. Animals were divided into 3 equal groups (6 for each). In first group (control): An end-to-end intestinal anastomosis was performed using simple interrupted suture pattern only. In group PG: The anastomosis site was sutured as in control group and was wrapped with PG. Where as in PRF+PG group: The anastomosis site was sutured also as in first group and was wrapped with PRF and PG. Healing process was studied in all above mentioned groups clinically, grossly, histologically and radiographically at 15 and 30 days post operation. Results were revealed that the utilizing of PG caused a valuable influence on anastomosis site healing. This impact was manifested by faster re-epithelization of mucosa, increased collagen deposition, fibroblast proliferation, reduced adhesions, and decreased stenosis degree comparison with control group. Also there was less adhesions, less stenosis degree, increased in epithelization of the mucosa in the group treated with PRF+PG than the group treated with PG alone. In conclusion the current study has shown that autologous peritoneal graft application has a positive and beneficial effect on intestinal anastomosis healing. Also the results highlighted the promising effects of PRF in conjunction with PG on intestinal anastomosis healing. The application of PRF with PG at the intestinal anastomosis site is successful, safe, and highly efficient with no complications.

This project evaluated the effects of nano magnesium oxide versus platelets rich fibrin on induced radial fracture bone healing. Eighteen males and nonpregnant females of adult local stray dogs, weighing 17.6±0.85 kg and aged 2.08±0.13 years, were used. These trials animals were randomly divided into three groups of equal numbers. In the first group, Control group (C), a transverse radial fracture was induced then immobilized by external fixation as gypsum. In this group, the fracture line was not treated with any bioactive material. In the second group, platelets rich fibrin group (PRF), the fracture line was treated by adding platelets rich fibrin. In the third group, nano magnesium oxide (NMO), the fracture line was treated by adding a suspension of nano magnesium oxide. The radiographic results showed that the fractured bone healing was faster in the second group than in the first and third groups, while the third group was better than the first group. The concentration rates of serum calcium and alkaline phosphatase were increased in the weeks followed the surgical operation. Depending on the radiographic pictures and serial rates of alkaline phosphatase, the second PRF and the third NMO groups were the better-fractured bone healing than the first one. In conclusion, this study revealed that using each platelets rich fibrin and nano magnesium oxide enhanced and improved the healing of the induced radial fracture.

To investigate the effects of systemic administration of Theranekron (Tarantula cubensis) extract as homeopathic remedy on anastomosis healing after surgical intestinal resection. Eight healthy stray dogs (age 1-1.5 years, weight 15-20 kgs) were randomly divided into two groups; control (4 animals) and treatment group (4 animals). Intestinal resection and anastomosis were performed in all animals in both groups. Theranekron D6 (3 ml) was administered subcutaneously one week before surgery and at operation time in the treatment group whereas animals of the control group were injected 3 ml of normal saline at the same time points of treatment group. All animals were kept for 15 days following surgery and a segment of intestine was removed for histopathological and press pressure measurement. The results showed that no post-operative complications have been observed in both groups. The gross examination of the anastomosis site revealed sever adhesions with omentum and other intestinal segment of the all animals of the control group in comparison to the treatment group where lesser adhesions with omentum without any adhesion with the other intestinal segment have been noticed. There was slight difference between control and treatment group in relation to histopathological examination. In conclusion, the findings of this study showed that Theranekron was able to improve the healing process of the resected and anastomosed intestinal segment

D-ɑ-tocopheryl polyethylene glycol succinate (Vitamin E TPGS or TPGS) has been approved by food and drug administration (FDA) as harmless adjuvant and is largely used in drug systems delivery. Physicochemical and biological possessions of TPGS provide many advantages for its usage in drug delivery, such as high bio-compatibility, increased drug solubility, improved drug penetration and selective anti-tumor action. The aim of the study was to use the TPGS polymer as a drug release model to regulate the release of the anesthetic xylazine-ketamine in order to minimize therapeutically reference dose, avoid side effects, and improve efficacy. The study performed on 15 adult local breed male rabbits, divided into 3 groups with same number which injected intramuscularly with single dose of suggested anesthetics. Group 1 injected with ketamine and xylazine. Group 2 injected with ketamine and xylazine as same dose of group 1 loaded by PLGA-TPGS. Group 3 injected with Ketamine and xylazine loaded by PLGA-TPGS with half dose of Group 1 and 2. The following physiological parameters were evaluated: heart rate, respiratory rate, degree of muscle relaxation, onset of action and stages of anesthesia before administration the drug at time zero then at 10, 30 and 60 minutes after drug administration, also induction of anesthesia, surgical anesthesia and recovery time were recorded. Nanoprecipitation technique was optimal method for preparing small particle size as well as reduce dose for therapeutic effect. Small and large dose was showed perfect analgesic and muscle relaxant activity of xylazine-ketamine drugs. Ketamine 30 mg and xylazine 10 mg loaded PLGA showed elevation of conciseness period as well as increase muscle relaxant. Ketamine 30 mg and xylazine 10 mg loaded PLGA reduce heart rate but onset of action delayed when compared with reference drug. The process of nanoprecipitation was ideal for forming small particle sizes and reducing the dosage for therapeutic effects. PLGA loaded with ketamine-xylazine demonstrated improved cycle concentration (walk time) as well as improved muscle relaxant, finally the protocol created an excellent anesthetic combination for induction of general anesthesia.

Glaucoma is a neurodegenerative disease identified by optic nerve damage and loss of retinal ganglionic cells. The aim of the study was to test the precise dose of trypsin to induce glaucoma in a rabbit model. Nine White New Zealand rabbits were randomly divided into three groups: Group one (G1) normal animals as control, group two (G2) the animals were injected with 0.2 ml of 0.04% trypsin and group three (G3) injected with 0.2 ml of 0.05% trypsin into posterior chamber of eye. A schiotz tonometer was used to measure intraocular pressure (IOP) before the injection, two days after injection and once a week until the end of the second week. At the end of the second week, the histology of the retina and optic nerve was studied. G3's intraocular pressure increased by 43.7%, while G2's intraocular pressure increased by 0.7% compared to G1. Retinal ganglionic cells (RGCs) decreased in G3 by 91.5% and G2 by 43.8% in comparison with G1. Optic nerve histology in G3 displayed decreased Schwann cell quantity with vacuolation and low orientation of nerve fibers compared with G1 and G2. Group three had the highest increase in IOP due to obstruction of drainage canal and preventing outflow of aqueous humor. This resulted in mechanical compression on the retina, ending with loss of RGC and degeneration of the optic nerve. The conclusion is that 0.2ml of 0.05% trypsin is the proper dose for the induction of glaucoma.

Periodontitis is a common inflammatory disease that leads to the degradation of periodontium and results in alveolar bone loss. The development of a suitable animal model of periodontitis is a prerequisite to understanding better the mechanisms that underly this disease. This study evaluated periodontal disease induction via retentive ligature, intragingival injection of lipopolysaccharide (LPS), and their combination in a rat model.Seventy-two Sprague Dawley rats were divided into four groups. The first group (control) did not receive any treatment. The second group underwent the application of 4/0 nylon ligature around the second maxillary molars. The third group was treated with an intragingival injection of Porphyromonas gingivalis LPS into the palatal mucosa of the second maxilla molars, and the fourth group was treated with a combination of ligature and LPS injection (ligature-LPS). Morphological changes in the gingival tissues were evaluated after 7, 14, and 30 days of treatment.Significant degenerative changes were observed in the periodontal tissues and alveolar bone in the third and fourth groups, which were evident as early as seven days. The lesions remained until 14 days and declined with time in the third and fourth groups. The changes induced by ligature and ligature-LPS were not different. Injection with LPS alone resulted in minimal increases in the Gingival and Plaque Indices.The ligature technique induced periodontal disease successfully, more effective than the injection of LPS. The combination of ligature with LPS injection added no significant effect compared to ligature alone.

The aim of the present study was to evaluate the effect of magnesium oxide nanoparticles and the role of the harmonic scalpel in lung tissue healing at the site of a middle lobe resection of the right lung. Twenty-four adult domestic dogs were used. They were randomly divided into two equal groups (control and treated group). The middle lobe of the right lung was excised by harmonic scalpel with titanium clamps to control bleeding and infiltration of air bubbles. The clinical and physiological condition of the animals was studied in the two-week period after surgery and molecular evaluation at time of zero, first, third, fifth, seventh, fourteenth, twenty-first, twenty-eighth, and thirty-fifth days after operation by interleukin-6 and tumor necrosis factor-α. The result of clinical observation showed that dogs in both groups took 2-4 days after the operation to gain full activity. The heart and respiratory rate were within the normal level before and during the operation, and when the animal began to recover, the heartbeat and respiratory rate began to rise with irregularity and the irregularity continued for 3-5 hours after the completion of the operation and then returned to its normal level within 24 hours after the operation. These changes in heart rate and respiratory system were observed in all treated animals, while heart rhythm and respiratory rates persisted in the control group until several days after the operation. In the molecular evaluation, the results for interleukin-6 and tumor necrosis factor-α showed a significant difference in the mean values ​​of these two factors between control and treated.

Low-level laser therapy (LLLT) was applied to alleviate pain with minimal adverse effects. This study was conducted to evaluate the analgesic effects of low-level laser therapy for pain control to help in surgical and emergency cases. The present study has demonstrated these effects experimentally on forty-five male albino mice weighing 45±5 grams. Creation of pain in animals was done by injection of 50µl of 5% formalin into the left posterior paw. Lifting of the paw was considered as an indicator of the pain. All animals were divided into 3 groups 15 mice in each group. In group A the LLLT 820nm.200mw, 48J/cm2 was focused on the affected paw for 1 min. In group B a diode laser with same dose in group A and different time used to irradiate the injected paw continuously for 30 seconds. The group C (control group); the laser probe was placed over the affected paw for concurrent but the apparatus was switched off. The results demonstrated that there were significant differences between group A and B when compared with group C during the 5 minutes as well as in 10 minutes and 15 minutes. Group A also registered a superior analgesic effect when compared with group B. Groups of LLLT were better than those found for control one and the irradiation continuous for one minute was better than 30 seconds at 5,10 and 15 minutes after the creation of pain.

The aim of this study was to evaluate the intensity of decorin in normal and the injured equine cadaver limbs. The study was carried out using superficial digital flexor tendon (SDFT) samples harvested from equine cadaver limbs. Randomly assigned left or right equine distal forelimbs were collected in normal (7 - 14 years old ± 2.86 SD) and injured (6 - 16 years old ± 3.64 SD) SDFT. Small pieces of approximately 5 x 5 x 3 mm were collected from normal and the injured areas at the mid-most metacarpal regions and fixed in 4% paraformaldehyde at room temperature. They were routinely prepared for H&E staining in order to confirm whether they were normal or injured. Then they were prepared for immunological assay, the primary and the secondary antibodies were prepared in a standard ratio. The results showed that the distribution of decorin was varied between fascicles and the interfascicular matrix (IFM), and the latter showed greater intensity than the fascicles. The injured tendons showed up-regulation of decorin, it was intensively expressed in all the cases of injured tendon, particularly fascicles showed significant up-regulation when compared to the normal tendon. It was concluded that decorin was varied regionally, and the injured tendons presented a significant up-regulation.

From a total of 734 clinical cases, 181 were diagnosed as fractures. From cases, dogs represented 49.72% (90/181), whereas cats represent 18.23% (33/181) and birds represented 22.09% (40/ 181). The etiology of the fractures multifactorial, but car accidents represented the main cause of fractures particularly in dogs. Femoral fractures were reported as the most prevalent types of fractures that represented 26.51% (48/181), followed by fractures in radius-ulna 19.33% (35/181), tibia-fibula 13.81% (25/181) and the pelvis 9.94% (18/181). All the cases were diagnosed on the bases of case history, clinical signs, physical examination and finally confirmed by using digital X-ray which offered an excellent scope and contrast than the traditional method. From a total of 181 cases, 6 cases were found hopeless, 45 cases underwent surgical internal fixation and the remaining 130 cases were fixed by external coaptation. Internal fixations were found to be very convenient and without any difficulties, on the contrary to the cases with external cooptation were not. We recorded postoperative inflammation in 4 cases, as well as mal-union was recorded in 5 cases and incomplete alignment in 2 cases was found. We concluded that fractures in pet animals are common in Sulaimani province, which must be considered, and the best-employed methods of fracture repair were the internal fixation techniques, particularly intramedullary pinning.

In secondary fracture healing, callus proliferate, undergo hypertrophy and the extracellular matrix becomes calcified. This step to some extent, recapitulates the embryological bone development with a combination of cellular proliferation and differentiation, increasing cellular volume and matrix deposition. The causes of the chondrocytes volume increase in secondary bone healing are poorly known, but cell membrane transporters perhaps could be implicated. We hypothesize that NHE-1 and AE-2 are among plasma membrane transporters that have a role in cellular differentiation and regulation of endochondral ossification for secondary bone fracture healing. Study of closed tibia fracture healing in 2 groups of 25 of 8-weeks-old Sprague-Dawley rats were undertaken and histological evaluation were made at 5 different time points at 1, 2, 3, 4, and 6 weeks after induction of the fracture. Histological evaluation of proliferative and hypertrophic chondrocyte zone area showed a significant difference in week 1 compared to other weeks. Immunohistochemistry study revealed a significant high level of labeling intensity of NHE-1 at the first four weeks. While labeling intensity of AE-2 showed moderate reaction at 1 and 2 weeks, that increased and reached the highest level at 3 and 4 weeks. These results suggested that NHE-1 and AE-2 had role in the endochondral ossification of secondary bone healing.

This study was designed to evaluate the using of two laparoscopic techniques for repairing an experimental cystotomy of urinary bladder reinforced with omental pedicle in dogs. Eighteen local breed male dogs were randomly allocated into two equal groups: first group an experimental cystotomy (about 2 cm) was induced laparoscopically at the ventral surface of the urinary bladder, repaired with titanium clips and reinforced with the omental pedicle. In the second group: similar technique was followed; however, the induced was repaired with hand-assisted extracorporeal laparoscopic method. In both groups, several diagnostic parameters were followed including clinical / laparoscopic exploration, radiology, and ultrasonography. Results obtained in the first group shown the titanium clips 4-6 clips freely applicated and whole time consuming for performing operation was 45±2.1 minutes. Clinically, the experimental animals didn't show any abnormal changes in their behavioral activities. Radiographic examination revealed distention of the urinary bladder accompanied by the presence of distances between the titanium clips; however, ultrasonography didn't show any leakage or thickness at the site of operation. Laparoscopic examination demonstrated mild adhesion between urinary bladder and adjacent organ. In the second group, the operation required 36±1.1 minutes to be completed. Postoperatively, no signs of pain were observed, however, animals demonstrated post-operative transient hematuria, lasts for 24 hours, accompanied with severe adhesion between the bladder and abdominal wall. Radiographically, regular distention of the bladder was revealed, while ultrasonographic examination showed hyperechoic dots and thickening of the bladder wall. We concluded that the hand-assisted laparoscopic cystorrhaphy strengthened by omentum is a practical, time saving and mini-invasive surgical technique.

The present article was aimed to assess the healing process of experimental entire rupture of Achilles tendon treated with various methods. The study was conducted on twenty-four healthy mature local breed dogs, which were randomly allocated in equal four experimental groups (6 of each). All dogs underwent complete Achilles tendon rupture and reconstructed as following: Group1 (control), animals were treated with tendorrhaphy only; Group 2, tendorrhaphy with platelet-rich plasma; Group 3, tendorrhaphy with a vein graft; and Group 4, the ruptured tendon was repaired with tendorrhaphy and augmented with vein and platelet-rich plasma. Dogs were monitored clinically and sonographically to evaluate tendon healing at 15, 30 and 60 days following the surgery. By comparison with the control group, the utilizing of plasma, with or without vein graft, enhanced the healing process of the induced rapture. Clinically, animals showed a fastest weight bearing and ultrasound imaging revealed increased echogenicity of fibrotic tissue. Clinically, the vein- platelet-rich plasma treated animal’s demonstrated early weight bearing, while animal treated with plasma showed earlier improvement in fiber pattern echogenicity. Furthermore, the using of vein graft for injury repair increased the repair process and the healing was earlier than that in the control group. In conclusions, our results suggested that the using of platelet-rich plasma with or without vein graft could enhance tendon healing and improve its mechanical function, which might be attributed to the synergistic effect of platelet-rich plasma with the vein graft.

The present study is assigned to throw the light on the benefit of using Kessler suture compared with polypropylene mesh implantation in healing of induced tenotomy of common calcaneal tendon in a rabbit model based on clinico-histopathological evaluation. Twenty adults New Zealand white male rabbits were used for this clinical prospective study divided equally and randomly into two groups. The first group, (suture group n=10) and the second group (mesh group n=10). Under the effect of general anesthesia, longitudinal skin incision over the common calcaneal tendon was made, and the skin flap was reflected. The tendon was isolated by blunt dissection from the surrounding tissue, with small curved forceps. Simulation of a rabbit’s common calcaneal tendon rupture was made by sharp transvers incision with scalpel. The first group repair with (Kessler Suture) using polypropylene suture size 4.0. In contrast, the second group repair with (polypropylene mesh implantation) after initial suturing of the cut ends of tendon by two simple interrupted stitches using polyglyconate suture size 4.0. The surgical skin wounds were re-stitched by simple interrupted pattern with 3-0 silk. After clinical follow-up of the treatment rabbits, certain secondary health problems were encountered represented by swelling of operative site and lameness. Grossly, adhesions were noticed between the tendon and subcutaneous tissue in rabbits of both groups. Microscopical examination reflected presence of inflammatory cells perivascular edema and few capillaries at two months. At the end of experiment there were perfect orientation and organization of collagen fibers in mesh group in comparing with suture group. Based on the results obtain from this study, it seemed that both groups reflected best outcome in healing of operated tendons with superiority of mesh group in comparing with suture group.

The aim of this study was to evaluate the effects of platelets rich fibrin and bone marrow on distal radial fracture healing in local breed dogs. Twenty four adult animals (males and females), mean aged 2.6 ±0.15 years, and the mean body weight 24.58 ±1.07 kg were used. The experimental animals were randomly divided into three equal groups. First group (Control group), transverse fracture was induced in the distal portion of radial bone and immobilized by Plaster of Paris, the fracture line didn't treated with any material. Second group (platelets rich fibrin group), the fracture line was surrounded by the platelets rich fibrin. Third group (bone marrow group), the fracture line was surrounded by autologous bone marrow. The radiographic results confirmed that the fracture healing was faster and superior in third group compared with first and second groups. The hematological results showed an increasing in concentration rates of alkaline phosphatase enzyme and calcium at the weeks that follows surgical operation. Depending on the serial rates of alkaline phosphatase, the third group and the second group are the better fractured bone healing than the first group. In conclusion, the results revealed that, the using of bone marrow and platelets rich fibrin improved and enhanced the healing of distal radial fracture.

This study aimed to measure the biochemical markers including alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transferase (GGT), alkaline phosphatase (ALP), creatine kinase (CK), total proteins, albumin, globulin, albumin / globulin (A/G) ratio, glucose, blood urea nitrogen (BUN), and total bilirubin in sera of dairy cows from the period of February-2016 to March-2018. For this purpose, 78 dairy cows of >3 years old reared at some areas of Baghdad province were subjected to blood sampling from the jugular vein. Study values (mean ± standard error) of ALT, AST, GGT, A/G ratio and total bilirubin markers were found outside the normal ranges of international reference values. Conversely, ALP, CK, total protein, albumin, globulin, glucose and BUN were found within the normal ranges of international reference values. To investigate changes that occur during late stage of pregnancy, study animals were dividedinto two groups (non-pregnant lactating and pregnant dairy cows). Statistically, significant decrease (P<0.05) was encountered in values (M ± SE) of ALT, AST, and GGT enzymes; and significant increase (P<0.05) in ALP and CK values of pregnant compared to non-pregnant dairy cows. Data concerning the serum proteins, results also indicated a significant increase (P<0.05) in values of total protein, whereas there no significant differences (P>0.05) were showed in values of albumin, globulin and A/G ratio. Pregnant dairy cows were showed a significant increase (P<0.05) in values of BUN and total bilirubin; however, glucose appeared without significant differences (P>0.05). It has been concluded that the lactation and gestation periods have a great impact on activity of biochemical indices in blood of dairy cows; therefore, there is a need for constant periodic monitoring for the described indices in this study to maintenance on animal’s health status.

This study was designed to evaluate the healing process of tracheal cartilage defect after implantation of two different biomaterials in dogs. Eighteen adult dogs from both sexes were used. They were divided into 2 equal groups. A window shape defect of about 3cm x 2cm was induced in the cervical part of three adjacent tracheal rings with their annular ligaments. In group one, the defect was closed with a small strip of ear cartilage (auto graft) from the same animal, while in the second group, calf's pericardium scaffold (xeno graft) was used to close the defect. All the animals were clinically monitored postoperatively, while gross pathological changes and biopsy collections for all animals was performed at 15, 30, 60 postoperative days. No postoperative clinical complications were recorded and all were looking healthy and resuming food and water intake normally. The gross pathological results revealed rapid occlusion to the trachea especially in first group and animals survived without any respiratory complications. The histological features in both groups were represented by newly granulation tissue formation and hyaline cartilage regeneration. The new hyaline cartilage cells formation was showed faster in group 1 rather than group 2. In conclusion, both grafts can be used for closing a tracheal defect in dogs with the priority of ear cartilage implantation.

The aim of this study was to evaluate the different methods of performing a Laparoscopic castration in dogs and to determine the efficiency and disadvantages of each of these methods. The study was conducted on 20 locally healthy dogs aged between 10-20 months and weights between 17-33 kg. The animals were randomly divided into four groups each group consisted of 5 dogs. In the first group, the castration was done by closed the ducts deferens with titanium clips, 4 clips were used, the average time for complete this surgery is (11.06± 1.19 Minute). The disadvantages of this method the possibility of failure to apply the clips. In the second group, laparoscopic castration was done by using Monopolar electrocautery, time requires for doing this operation is (34.85 ± 10.15 min.) the disadvantages of this technique bleeding may occur during cutting the spermatic cord, and the smoke of Monopolar electrocautery which impedes the vision of the surgeon. In the third group, extracorporeal ligation technique was used. This method proved highly efficient and prevented any bleeding because we did not need to cut the blood vessels, as well as the low material cost of this method compared to the other three groups. However, the time required to perform this procedure in this way was rather long compared to the remaining three groups where the time required to conduct the surgery is (36.82 ± 7.18) minutes and the disadvantages of this method is the tightening and twisting the blood vessels during pushing the knot to put her in the place as well as the length of the surgery time. While in the fourth group the laparoscopic castration was done by thermal cautery in which the clotting and cutting of blood vessels in the spermatic cord were done in the same tool, the time required to complete this surgery is (11.91±3.73 min). All the operations were performed under general anesthesia using Ketamine HCl 5% in dose 15mg/kg B.w and Xylazine 2% and 5 mg/kg B.W) as bolus i.m injection. Blood was collected from each animal before the surgery and 14, 30 days after the surgery to measure the level of testosterone hormone in the serum. The results showed there is no significant decrease before and after the surgery in the testosterone serum level. The testis was removed one month after the surgery to observe changes in testicular tissue and epididymis, there were hemorrhagic areas, necrotic regions, glomerulosclerosis and adhesions between the tunica vaginalis and the tunica albuginea. As well as the spermatozoa was stopped. Absences of the sperm in the epididymis (spermatogenia), also there are degenerative and necrotic changes in the epithelium of the epididymis and absence of the cavities of these nuclei in the sperm. We conclude from this study that laparoscopic castration in dogs can be performed in all methods which are mentions above, however, the thermal cautery method was the best method in terms of time, safety and economic cost.

The aim of this study is to tissue engineer a 3D scaffold that can be used for load bearing segmental bone defects (SBDs) repair. Three different scaffolds were fabricated using cockle shell-derived CaCO3 aragonite nanoparticles (CCAN), gelatin, dextran and dextrin with coated framework via Freeze-Drying Method (FDM) labeled as 5211, 5211GTA+Alginate, 5211PLA. Scaffolds were assessed using Scanning Electron Microscopy (SEM). The cytocompatibility of the organized scaffolds was assessed using cells multiplication and alkaline phosphatase (ALP) concentration via In Vitro cell culture using human Fetal OsteoBlast cells line (hFOB). The results showed a substantial difference in ALP concentrations between the cultures of different scaffolds leachable medium during the study period. The biological evaluation also showed that three scaffolds did enhanced the osteoblast proliferation rate and improved the osteoblast function as demonstrated by the significant increase in ALP concentration. Engineering analyses showed that scaffolds possessed 3D interconnected homogenous porous structure with a porosity ranging 6%-49%, pore sizes ranging 8-345 µm, mechanical strength ranging 20-65 MPa, young’s modulus ranging 166-296 MPa and enzymatic degradation rate between 16%-38% within 2-10 weeks. The in vitro evaluation revealed that the scaffold 5211, 5211GTA+Alginate and 5211PLA fulfill all the main requirements to be considered as an ideal bone replacement.

The aim of the present study was to evaluate treatment of 20 dogs with femur fractures. Twenty (20) dogs with different ages, breeds, and gender admitted to the clinic of Department of Surgery, Anesthesiology and Radiology-Faculty of Veterinary Medicine-Zagazig University from January 2013 to December 2015 with a complaint of hind limb lameness and were diagnosed as femur fractures through clinical and radiographic examination. German shepherd dogs (85%) and immature dogs (70%) were more susceptible to femur fractures. The most common site of the fracture was the femoral diaphysis (65%) followed by metaphysis (20%). Open reduction and internal fixation techniques were applied using intramedullary (IM) pins with or without cerclage wire (40%) and bone plate (15%) for treatment of diaphyseal fractures, and two cross pins (30%) for treatment of metaphyseal and distal physeal fractures. Pin migration after complete healing (1 case) and bone re-fracture due to jumping (1 case) was the postoperative complications. It was concluded that open reduction and internal fixation methods are the proper treatment for femur fractures if the proper surgical techniques were applied.

 The objective of this study was to determine the effects of the general anesthesia on same biochemical changes in donkeys. The anesthesia was induced by intravenous (IV) injection of romifidine 0.1 mg/kg as a premedication, after 5 minutes induction of general anesthesia by (IV) of mixture midazolam 0.1 mg/kg and ketamine hydrochloride 2.2 mg/kg in the same syringe. The maintenance of anesthesia was performed by (IV) infusion of a mixture of the midazolam 0.065 mg/kg/hr. and ketamine 6.6 mg/kg/hr. The biochemical parameters changes in serum levels of Aspartate aminotransferase (AST), Alanine aminotransferase (ALT) and Alkaline phosphate (ALP) activity as liver enzymes and serum glucose were estimated in zero, 15, 30, 60, 120, 240 and 480 minutes. The results revealed significant differences (P<0.05) in the means of AST (U/L) between zero 199.6 with 30 min 192.5 and 60 min 191.5. No significant differences (P>0.05) in mean enzyme activity of the ALT and ALP. Serum glucose results were shown no significant differences (P>0.05) in the (control, 15, 30 minutes) and (60,120 and 240) respectively and significant differences in between and within 480 minutes. The general anesthesia in this protocol was good and had little effect on the liver function and showed increase in serum blood glucose in donkeys.

The objective of this study was to evaluate the use of 3 types of non absorbable suture materials in arteries and veins suturing. Twelve adult dogs of both sexes was used, the animals was divided into three groups of four animals in each. The right common carotid artery and left jugular vein of each animal was used for application of suture materials. In group one the blood vessels (common carotid artery and jugular vein) sutured with polypropylene suture after inducing about 2cm longitudinal incision on the vessel, in group two polyester suture was used in the same manner of group one, while in group three myo-steel suture was used in the same way of group one and two. The macroscopic and microscopic changes associated with each suture material were studied at 15 and 30 postoperative days. The gross pathological changes associated with polypropylene was that of very mild adhesion and very mild shrinkage and stenosis at the suture line with smooth blood flow, while the groups of polyester and myo-steel suture associated with severe adhesions, shrinkage at the suture line with poor blood flow. The histopathological changes showed that polypropylene suture lead to formation of very few amount granulation tissue at the line of incision, no signs of organized thrombus formation or significant changes of the blood vessels wall, but the polyester suture cause arterial organized thrombus formation and hypertrophy of endothelial wall, while the myo-steel suture lead to formation intense amount granulation tissue which cause to the thickening in the wall of blood vessels with subsequent changes in the normal shape of vessels. In conclusion the polypropylene suture was regarded better and superior than polyester and myo-steel suture materials in blood vesselssurgery.

The present study was designed to evaluate the feasibility and safety of laparoscopic partial hepatectomy via two techniques in rams. Twenty-four adult local breed rams were used, which divided randomly and equally into two groups. All animals subjected to laparoscopic partial hepatectomy. operations were performed under the effect of general anesthesia by using 5% thiopental sodium at a dose rate of 15 mg/kg B.W., intravenously and maintenance was done by inhalation (halothane) (2- 2.5%). Animals placed in a reverse Trendelenburg (30º) and left lateral position. Pneumoperitoneum was achieved under (10 - 12mmHg). Four (10 mm) ports were made on ventral abdominal wall. Liver parenchyma was controlled with modified liver clamp. In first group, partial hepatectomy was done by Clamp-crush forceps. While in second group, Ultra- surgical device was used. Following operations, certain parameters such as rectal temperature, respiratory rate, heart rate, food intake, and secondary health problemes had been recorded. Also the operative and resection times and blood loss were estimated. Liver enzymes (alinine transaminase, aspartate transaminase, alkaline phosphate, total serum bilirubin and total serum proteinswere measured. Histopathological examination of liver biobsies was performed at 3rd, 7th, 15th days and four months post-surgery. The main intra-operative complication was the bleeding. Result indicated that the vital parameters were within the normal rang. Shorter operative and resection times were noticed in second group when compared with first group. There were no significant differences in the mean values of blood loss in both groups. Also no bile collection were seen in the abdominal cavity or subphrinic region during the exploratory laparoscopy at (3, 7, and 15 days) and four months post-surgery. There were no significant differences in the mean values of the liver function test (liver enzymes) in two groups. Macroscopic examination revealed the presence of adhestion between liver and adjcent structures with varing degree. The normal structures of the liver which consist of hepatocytes and central vein returned within 4 months post operations in second group. We can conclude that the laparoscopic partial hepatectomy in rams can be safely performed under Ultra-surgical technique with a modified liver clamp which reflected minor secondary complications and early liver regeneration.

 The present study aimed to take an idea about the efficiency of modified using ruminal ring for rumine fixation in sheep. Five awasi ewes underwent digestive disorders according to its signs and case history these cases diagnosed as foreign body syndrome. Rumenotomy was performed, rumen fixed with modified winghart ruminal ring, time consuming and degree of contamination this criteria used as index to estimate the efficiency of this method of fixation during operation. Blood picture, physical criteria and clinical inspection include postoperative complications was recorded during one week to evaluate the activity, efficiency, its prognosis and postoperative complications of current method of rumen fixation.  The results exhibited bloat, loss of appetite signs accompanied with foreign bodies in most of operative animals, so fixation of rumen with such modified ring suitable for laparorumeotomy in sheep because of less postoperative complications. In spite of that there is some difficulty with using this technique as large volume of ring which some time led to slipping of ruminal hocks and the ruminal content may enter to the abdominal cavity.  There were no significant changes in physical and blood criteria. Data suggest hat rumenotomy can be easily done in sheep with a modified winghart ring.

Ninety-three of grossly normal buffalo genital tracts were under taken in this study. The mean length, width, thickness, and weight of the ovary devoicing functional Corpus Luteum (CL) were 2.39±0.77 cm, 1.55±0.46 cm, 1.19±0.31 cm and 3.12±2.11 gm, respectively, and 2.139±0.65 cm, 1.23±0.3 cm and 3.14±1.86 gm, for the left one respectively. The mean length, width, thickness and weight of right ovary containing functional CL were 2.61±0.52 cm, 1.59±0.45 cm, 1.53±0.24 cm and 4.79±1.59 gm respectively, and 2.88±0.60 cm, 2.34±0.38 cm, 1.48±0.15 cm and 5.54±1.23 gm for the left one respectively. The mean diameter of the largest six follicles located on the right ovary was 1.42±0.19 cm, and 1.41±0.1 cm of six follicles on left ovary. The mean length of prominent part of the 15 functional CL found on the right ovary was 0.57±0.17 cm and it was 0.57±0.21 cm on the left one, while the mean length and weight of those 15 functional CL of the right ovary were 1.151±0.18 cm and 1.31±0.52 gm, and on the left ovary they were 1.73±0.93 cm and 1.7±0.57 gm. The mean length, diameter and number of caruncles of the right uterine horns were 23.76±8.14 cm, 2.12±0.6 cm and 84.63±13.62 respectively, and they were 23.34±7.96 cm, 2.10±0.58 cm and 84.12±13.27 of the left horns respectively. The mean length and numbers of uterine body caruncles were 1.37±0.75 cm and 6.27±1.92 the mean length, diameter and number of annular rings of cervix were 5.33±0.96 cm, 2.58±0.64 cm and 4.7±0.61, respectively.
