First the ultrasonography of the organs (out of the body) was carried underwater, then the ultrasonography of the alive fish was done. Finally, dissection was used to compare the anatomy and ultrasonography results.Results- There are folds on the internal surface of the esophagus. The esophageal wall was thin and hyperechoic with no clear layers. The proventriculus wall was visible as a completely hyperechoic layer in the region where it was attached to ventriculus. The muscular layer of the ventriculus was thicker than that of proventriculus. The pyloric caecum was seen to be located posterior to the ventriculus as a completely hypoechoic layer while the details were unclear. The wall layers of the small intestine were comprised of the 4 parts. The wall layers of spiral colon consisted of the 4 parts to.Conclusion and Clinical Relevance- The study also presented a standard ultrasonography approach for the digestive canal of adult Persian sturgeon.

Afterward, the dogs were randomly assigned to two groups which received 20 ml/kg lactated Ringer's solution or 5 ml/kg Hydroxyethyl starch, in four consecutive 15 minutes intervals (fourth stage of assessments). One hour after the last resuscitation step, final ultrasonographic assessments were performed.

The elevation of tissue temperature following of cryptorchidism could induce oxidative stress which influences the cellular and tissue degeneration. Amlodipine is a third-generation of calcium channel blockers which has antioxidant activity. The aim of this study was to evaluate the protective effects of amlodipine on testicular tissue alterations in an animal model of cryptorchidism. Design- Experimental study Animals- Thirty adult male Sprague-Dawley rats weighing 200-220g Procedure- Experimental cryptorchidism was induced in adult rats. Amlodipine (10 mg/kg b.w.) was administrated orally for two and four consecutive weeks. The experimental groups consisted of non-treated cryptorchidism (n=10) and treated cryptorchidism (n=10) groups. Testicular tissue samples were collected on days 14 and 28 following of cryptorchidism form non-treated and treated groups. Histopathological and morphometrical studies with the evaluation of microscopic indices of spermatogenesis were prepared on tissue samples. Results- Tubular atrophy with germinal epithelium disarrangement was observed in cryptorchidism groups. These changes were reduced dose-dependently in treated animals. The mean of Sertoli cells was reduced significantly (p=0.025) in four weeks non-treated and the mean of germ cells lineage was reduced significantly (p<0.0001) in four weeks non-treated and two weeks treated cryptorchidism groups compared to the control group. Similarly, all microscopic indices of spermatogenesis were reduced following the induction of cryptorchidism. These alterations were reduced time-dependently in amlodipine treated groups. Conclusion and clinical relevance- The results of this study revealed that the administration of amlodipine as an antioxidant agent, time-dependently could be effective on the reduction of cellular and tissue damages of testicular tissue induced by cryptorchidism. It seems some parts of these protective effects may be done through its activity as calcium blocker which declines apoptotic processes by reduction of cytoplasmic calcium levels.","PeriodicalId":14554,"journal":{"name":"Iranian Journal of Veterinary Surgery","volume":"14 1","pages":"116-124"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49527638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
