Objective- This study was conducted to make a full understanding of the anatomic and ultrasonographic characteristics of digestive canal in Persian Sturgeon and provide standard approaches for performing digestive tract ultrasonography on this sturgeon species.Design - Experimental studyAnimals - 30 mature Persian sturgeons (Asipencer persicus) (15 females and 15 males)Procedures- A potable ultrasonography machine was used and proper approaches were chosen according to the anatomical examination. 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. According to this study the places of locating probe for digestive ultrasonography are between the pectoral fines for Esophagus, Liver, ventriculus, Proventriculus, Proximal part of the right pectoral fine for gallbladder and liver, Distal part of the left pectoral fine for ventriculus and pyloric caecum, Posterior to the pectoral fines for small intestine, Anterior to pelvic fines for small intestine and spiral colon and between pelvic fines for rectum, spiral colon, connection between the rectum and spiral colon.

Objective- The aim of this study was to evaluate possible beneficial effect of tricalcium phosphate/collagen (TCP/collagene) nanocomposite scaffold on bone healing in rabbits using biochemical assessmentsDesign- Experimental studyAnimals- Twelve healthy male white New Zealand rabbitsProcedures- The rabbits were marked with non-toxic color and randomly divided into two groups of 6 animals each. In the first group (SHAM) the defect was made and with no treatment the wound was closed. In the second group (TCP/C) the tricalcium phosphate/collagen (TCP/collagene) nanocomposite scaffold was implanted into the defect. Before the procedures (day 0) and on 7, 15, 30, 45 and 60 postoperative days the blood samples were taken from jugular vein and undergone hematological and biochemical assessments.Results- The hematological, biochemical and oxidative stress parameters including WBC, RBC, HCT, PLT, neutrophil, lymphocytes, BUN, Creatinine, AST, ALT, ALP, SOD, GPX and MDA showed statistically significant differences between Sham and TCP/C groups (p<0.05). Conclusion and clinical relevance- It was concluded that TCP/collagen nanocomposite improved the biochemical parameters in the nanocomposite treated animals and could be of clinical benefit in reconstruction of bone defects and could be considered as a scaffold in bone fractures.

Objective- The pineal gland and its principal hormone melatonin play an important role in the circadian organization in birds. However, little is known about the role of melatonin in cardiac activity of broiler chicken. The aim of this study was to assess the impact of intracerebroventricular injection of melatonin in electrocardiographic parameters, heart rate and mean electrical axis in broiler chickens. Design- Experimental study. Animals- Forty male Ross broiler chickens Procedures- Ross broiler chickens received intracerebroventricularly (ICV) melatonin. All ECGs were standardized at 1 mV = 20 mm, with paper speed of 50 mm/sec. Leads І, ІІ, ІІІ, aVR, aVL and aVF were recorded. Results- Injection of melatonin (200 nmol) increased the duration of T wave and QRS complex and declined the heart rate as compared to the control group (p<0.05). Mean electrical axis, calculated from leads ІІ and ІІІ, did not differ between groups and it was between -93° and -99° in all chickens. Conclusion and clinical relevance- Exogenous melatonin intracerebroventricularly results in sinusoidal bradycardia in broiler chicken

Objective- The aim of this study was to assess ultrasonography-derived caudal vena cava to aorta ratio (CVC/Ao) as a novel endpoint in the resuscitation of experimental hemorrhagic shock in dogs. Design- Experimental study. Animals- Ten adult mongrel healthy dogs. Procedures- After induction of anesthesia (control assessments), hemorrhagic shock was induced by blood withdrawal to a mean arterial pressure of 40 to 50 mmHg within 30 minutes and then maintained in a hypovolemic situation for an additional 30 minutes (second and third stages of assessments). 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. Results- Hemorrhagic shock caused a significant decrease in the CVC and Ao diameters as well as the CVC/Ao (2.14 ± 0.28 cm, 0.85 ± 0.07 cm and 0.4 ± 0.06, respectively) (p<0.05). Following the fluid resuscitation, CVC/Ao increased and returned to pre-shock values in both groups. Conclusion and clinical relevance- Findings indicated that serial ultrasonographic assessment of the CVC/Ao can be a useful endpoint in the resuscitation of dogs with hemorrhagic shock.
目的-本研究的目的是评估超声检测的尾侧腔静脉与主动脉比率(CVC/Ao)作为实验性失血性休克复苏的新终点。设计-实验研究。动物- 10只健康的成年杂种狗。程序-麻醉诱导后(对照评估)，在30分钟内通过抽血诱导失血性休克至平均动脉压40 - 50mmhg，然后再维持低血容量状态30分钟(第二和第三阶段评估)。随后，狗被随机分为两组，每组服用20 ml/kg乳酸林格液或5 ml/kg羟乙基淀粉，连续4次，间隔15分钟(第四阶段评估)。最后一次复苏1小时后，进行超声检查。结果-失血性休克导致CVC、Ao直径及CVC/Ao分别降低(2.14±0.28 cm, 0.85±0.07 cm, 0.4±0.06 cm) (p<0.05)。液体复苏后，两组CVC/Ao均升高并恢复到休克前值。结论和临床意义-研究结果表明，连续超声评估CVC/Ao可作为失血性休克犬复苏的有效终点。

Objective- Cryptorchidism, common birth defect of the male genital tract, is one of the causes of fertility problems. 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.

Case description- A four-year-old Kurdish ewe was referred to the Animal Clinic of Faculty of Veterinary Medicine of Razi University (Kermanshah, Iran) with cheek swallowing, infection wound and impaction of the food in right cheek for several weeks. Clinical findings- Clinical examination revealed stretching and laxity of the cheek muscles with buccal food impaction and skin infection of this area because of previous unprofessional incision by her owner. No dental or other oral cavity abnormalities were observed on examination or palpation after manual expelling of the impacted feed and irrigation of the mouth cavity. Treatment and outcome- After treatment of the animal by Intramuscular penicillin-streptomycin solution (20000 IU + 10 mg/kg bw) and flunixin meglumine (2 mg/kg bw) for three days; the defect was surgically repaired under sedation and local infiltration anesthesia. No post-surgical complications were encountered during three months post-surgery. Clinical relevance- This report describes a complicated buccal food impaction in a ewe and some causes of this disorder and its surgical correction, which may be the first written report in the sheep in Iran. It could be hypothesized that dietary causes, may be a contributing factor to the development of buccal food impaction in this case.

Objective-The aim of the present study was to investigate the effects of curcumin nanoparticles (CNP) on stress oxidative following experimental ischemia-reperfusion injury in the rat testes. Design-Experimental Study Animals- Seventy-seven healthy male Wistar rats Procedures-The animals weighing approximately 250 g were randomly assigned to four experimental groups (n = 18): Ischemia: torsion group (created by 720° rotation of testis on both sides for 2 h). Ischemia/Reperfusion (I/R): torsion for 2 h followed distortion, CNP 10: received 10 mg/kg IP administration of CNP 30 min before surgery then remaining testes were twisted and untwisted, CNP 20: received 20 mg/kg IP administration of CNP 30 min before surgery then remaining testicles were twisted and untwisted. Unilateral orchiectomy of left or right testicles was performed on days 0 and 12 with immediately sampling. Some twisted then untwisted testicles were remained and sampled 60 days after surgery. An additional group was considered (n=5) to be sampled without any operation as control group. The samples of testicular tissue homogenates were taken on Days 0, 12 and 60, and their liquid extracts were collected and assayed for Superoxide dismutase (SOD), Malondialdehyde (MDA) and Glutathione peroxidase (GPX). The effect of treatment and day of sampling on the variables was analyzed using Two-Way ANOVA. Results- The results of the study showed an ameliorated balance of GPX, SOD and MDA following testicular torsion in this study. The CNP treated animals (with both administered doses) showed significantly improved the balance of the enzymes compared to untreated animals (p<0.0001). Conclusion and clinical relevance- In conclusion, IP administration of CNP may be helpful in minimizing oxidative stress related enzymes following testicular ischemia-reperfusion in rat.

Objective- This survey was accomplished to describe the hepatic artery and portal vein indices in healthy domestic cats by color Doppler ultrasonography technique. Design- Retrospective experimental study. Animals- Twenty domestic short hair (DSH) cats (10 males and 10 females). Procedures- Doppler indices of liver vascular (portal vein and hepatic artery) such as PSV, EDV, RI, PI, MV, VF and the spectral wave forms were measured in the studied cat's population (two equal groups of ten each). Results- The mean and deviation of portal vein were as follow: PSV: 40.68 ± 9.82‚ EDV: 23.38 ± 5.78‚ RI: 0.48 ± 0.10‚ PI: 0.72 ± 0.26‚ MV: 2.49 ± 0.64, VF: 25.81 ± 5.04 and for hepatic artery were included PSV: 49.79 ± 9.45‚ EDV: 31.92 ± 5.05‚ RI: 0.59 ± 0.09‚ PI: 0.85 ± 0.20‚ VF: 34.73 ± 5.47 and MV: 3.03 ± 0.44 respectively.Conclusion and clinical relevance- The obtained results showed that there was not a significant difference between males and females for indices of liver vascular (p>0.05). These data can be used for comparison with the various hepatic diseases in cats. It should be noted that the importance of hepatic blood flow is more in cats than dogs, due to defect in liver enzymes.

Case description- A five-year-old female dog, weighing 35 kg, was presented as an emergency case after it suffered a gunshot injury.Clinical findings - Physical examination of the dog revealed paraplegia, the symptoms were normal. There was no bone fracture and dislocation in the lower extremity examination. A bullet (diameter, 4 mm) between the third and fourth lumbar was observed on radiographic examination.Treatment and outcome- The bullet was about 4 × 7 mm long, which stuck between the longitudinal spine and carefully removed. In the examination of the spinal cord, the rupture was observed relatively in some longitudinal strands, and no necrosis was present in the site. After the surgery, the dog was discharged with a good condition.Clinical relevance- As a consequence, a precise evaluation of the gunshot injury to the spinal cord could not be achieved by imaging, which made a prediction of the prognosis difficult prior to surgery. Therefore, if imaging tests provide evidence of a direct impact on the spinal cord, surgery should be considered a primary method to prevent irreversible harm necrosis of the spinal cord.
