The aims of the current study were a definitive diagnosis of left displaced abomasum by using ultrasonography furthermore determination of abomasal position and measurements. Study includes sixteen local cattle breed, six have anorexia, weakness and drop milk production, on clinical examination there was decrease rumen contractions 3.6 \ 5 minutes, furthermore a pinging sound heard on auscultation of left intercostal spaces there were diagnosed as left displaced abomasum, other ten clinically healthy cows considered as normal control group. Ultrasonographic imaging was performed for stand nonsedated cows by use 3.5-5 MHz transducer at the ventral midline and in the intercostal spaces 9, 10, 11, and 12 from the left side. Ultrasonography revealed a left side displaced abomasum to an area between the abdominal wall and the rumen, which appeared as hypoechoic fluid content ventrally and hyperechoic parallel echogenic lines of gas gap dorsally, abomasal folds appear as filiform echogenic lines. While in healthy cows an abomasum located in the ventral midline and directed mainly to the right side. In conclusion, ultrasonography as a non-invasive technique could be used as a confirmative diagnosis of left displaced abomasal and help for differential diagnosis of left abomasum displacement a well as can be useful for measurement of abomasum in healthy local breed cattle.

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.
