The abuse of this compound, especially for muscle growth, has severe oxidative side effects on the liver and kidneys. Oxidative stress and free radicals are responsible for the development of various diseases. Phytochemicals are sources of polyphenols, flavonoids, saponins, etc. and may act as scavengers of free radicals. Saffron (Crocus sativus) has considerable antioxidant properties, which may be useful in reversing or preventing these negative effects. To evaluate the effects of saffron on the liver and kidneys degenerative changes induced by oxymetholone, 24 male Wistar rats were used. The rats were randomly divided into four groups of six rats each as: a) sham (normal saline, 40 mg/kg/day), b) saffron control (40 mg/kg/day), c) oxymetholone (50 mg/rat), and d) treatment group [saffron (40 mg/kg/ day)+oxymetholone (50 mg/rat)]. The course of examination was 30 days. Results: After one month, the sham and saffron control groups had normal histological findings. The treatment group with saffron showed a significant reduction in the hepatic and renal degenerative changes induced by oxymetholone compared to those observed in group. Based on the histopathological results, the use of saffron produced protective effects against the degenerative changes in rats' liver and kidneys induced by oxymetholone.

It persists in the environment and causes reproductive problems in both human and animals. The present study was aimed at protective effect of green tea against ATZ toxicity in the reproductive system of male rats. Methods: The present study was performed in Veterinary School, Shahid Bahonar University of Kerman in 2016. ATZ and treatment groups received ATZ daily 200 mg/kg BW orally for 14 d. In addition, 0.2% methanolic green tea extract was administrated in the treatment group. Results: In histopathologic investigation, number of germinal layers reduced in the most seminiferous tubules in the ATZ group and spermatids were absence. Necrotic spermatocytes, spermatids, and spermatozoa were evident in the testicular tubules. In the morphometric measurements, tubular diameter, germinal epithelium height, and meiosis index decreased significantly. Conclusion: Green tea extract had reduced testicular toxicity of atrazine significantly. ATZ induces toxicity through oxidative damage and green tea extract can protect the testes due to antioxidant activity of its polyphenols especially flavonoids.

Grossly, the mass protruded from the surface was located on the hairless and unpigmented areas of the right hock joint with ulceration and dried hemorrhagic foci. On microscopic examination, ulceration, hemorrhage, as well as hyperkeratosis were observed. Large round, oval to polygonal neoplastic cells extended into the dermis were arranged to form cords, trabeculae, islands or glandular-like structures without keratin pearls. These pseudoglandular structures were composed of pseudolumina containing acantholytic and detached tumor cells. Necrosis of the neoplastic cells was accompanied by infiltration of inflammatory cells particularly heterophils. Unlike pleomorphic tumor cells, mitosis count was almost frequent. No evidence of other abnormalities and tumor metastasis was found. These gross and microscopic features appeared to be suggestive of a rare histologic var...

In animals, haemangiosarcoma is frequently reported in dogs as a visceral tumour. The present study describes a gingival haemangiosarcoma in a 2-month-old, female native breed calf with a tumour likemass on the gingiva. The owner had noticed the mass 2 weeks after birth due to salivation, bleeding and halitosis. It had rapid growth and caused anorexia and weight loss in the animal. Histopathologic examination showed a lot of thin-walled, irregular blood vessels lined by a single and less commonly two layers of endothelial cells. The lining cells were with spindle or ovoid shape with vesicular to hyperchromatic nuclei and prominent nucleoli. There were remarkable thrombi in some vessels. The reported lesions were diagnosed as haemangiosarcoma based on histopathologic characteristics such as irregular vascular canals and polymorphism of neoplastic endothelial cells. Haemangiosarcoma is rare in the oral cavity of cattle.

This microorganism and Mycoplasma arginini have been routinely recovered from young lamb with "coughing syndrome". In this study, a polymerase chain reaction (PCR) based 16S RNA gene sequences was used for detection of M. ovipneumoniae and M. arginini in pneumonic lungs of slaughtered sheep. The lungs of 1000 sheep carcasses were grossly inspected at local abattoir. Pneumonia was detected in 40 (4%) of the carcasses. M. ovipneumoniae and M. arginini were identified in 20% (n=8/40) and 2.5% (n=1/40) of ovine pneumonic lungs respectively. The pathologic findings associated with M. ovipneumoniae were including suppurative bronchopneumonia, fibrinous bronchopneumonia and interstitial pneumonia.

It is common in small ruminants. The cysts in sheep are more cerebral, while are noncerebral in goats. Coenurosis decreases production, and results in the death of the affected animals and in the disposal of the organs or even carcasses in severe infection. The present study describes severe subcutaneous coenuri associated with contamination in other tissues including the skeletal muscles and visceral organs. A remarkable clinical observation was the aggregation of cysts in variable sizes in the subcutaneous tissue of whole body. Subcutaneous tissue is not a common site for cyst formation. Coenurosis was confirmed based on the morphological characteristics of the cysts including the clusters of protoscolices and rostellar hooks.

During surgery, foetus was not found and both of the uterine horns were distended with a lot of liquid. Multiple welldemarcated nodules of firm consistency, yellow-tan colour and 2.5–4 cm diameter were projected from the cotyledons into the lumens. Histopathologically, the nodules showed expanded chorionic villi composed of proliferated blood vessels in a variable amount of loose perivascular stroma. Syncytial trophoblast cells with hyperchromatic nucleus were dispersed in the tumour’s parenchyma. Based on pathologic characteristics and according to the abundant vascular proliferation and nodular form, a neoplastic lesion named chorangioma was diagnosed. To the author’s knowledge, it is the first report of chorangioma in sheep.

In Traditional Iranian Medicine (TIM), administering equal weights of starch with this plant is suggested to produce more tolerable preparations from it. Hence, we assessed histopathological changes in rat liver and intestine after using starch as corrective agent. Methods: We designed three experiments in Veterinary Medicine School of Shahid Bahonar University in Kerman, Iran in 2016. The procedure was applied in 2016 for 15 days. In the first experiment, group No. 2 and 3 received single daily dose of alcoholic pulp extract of C. colocynthis at 300 and 600 mg/kg extract consecutively. In the second experiment, group No. 4 and 5 received 300 and 600 mg/kg extract plus the same amount of starch consecutively. In the third experiment, group No. 6 and 7 received extract at 300 and 600 mg/kg plus the three times weight of starch consecutively. The live rats were euthanized and their liver and intestine were removed for histopathology examination. The samples were stained with hematoxyline-eosin (H&E). Results: Rats in all of the groups died from bleeding and diarrhea except for group No.6 that showed no symptoms seen in other rats. Microscopic examination of their intestine showed no histopathological lesions or other degenerative changes of the epithelium. Conclusion: Clearly further works in modern phytotherapy will be required to delineate the role of starch in reducing C. colocynthis toxicity. Consumption of adequate weight of starch with the toxic dose of C. colocynthis make it safe for digestive system but could not prevent necrotic changes in the liver.

In the veterinary literature, ectrodactyly has been described in dogs and domestic cats as a rare congenital heterogeneous disorder. The current report has described unilateral ectrodactyly in the left hindlimb of two born foals in an area with presence of Iranit and zinc manufactures. One of the foals was lack of the third phalanx and the other one had not the third and second phalanxes. No other abnormality was found in these cases. Various teratogens may be responsible for occurring skeletal anomalies. To the best of our knowledge, the present study is the first report of ectrodactyly in horse.
