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.

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.

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 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 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.

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.
