Dried Nerium oleander leaves at single lethal dose of 110 mg/kg body weight were administered orally to six native male sheep. Clinical signs of toxicosis in sheep began to appear about 30 min after receiving the oleander and included decrease of the heart rate followed by cardiac pauses and tachyarrhythmias; ruminal atony, mild to moderate tympany,(More)
UNLABELLED This study was designed to evaluate the effectiveness of crocin, main component of Crocus sativus L. (Saffron) against subchronic diazinon (DZN) induced cardiotoxicity in rats. METHODS Rats were divided into 7 groups; control (corn oil, gavage), DZN (15 mg/kg/day, gavage,), crocin (12.5, 25 or 50 mg/kg/day, i.p) plus DZN, vitamin E (200 IU/kg,(More)
Twenty-four 10- to 16-week-old calves in a dairy herd in Birjand, Iran, inadvertently received an excessive dose of salinomycin mixed with barley grain. There was 58% mortality within 10 d. The calves had high serum AST, LDH, and CK activities; histopathologic lesions in myocardium, liver, and kidneys; and clinical signs associated with acute and congestive(More)
Diabetes mellitus is a major manifestation of metabolic disorder which presents with hyperglycemia (high levels of serum blood sugar). In the present study, we aimed to investigate the effects of celery seed extract on different biochemical factors and histopathological changes in normal and streptozotocin (STZ)-induced diabetic rats. A total of 35 male(More)
Toxic effects of monensin, a polyether antibiotic mainly used as a coccidiostat, have been described in a wide range of animals. The present study was performed to investigate the toxic effects of monensin in goats. Seven adult goats were administered sodium monensin, 13.5 mg kg(-1), daily for five consecutive days via gastric gavage. Monensin toxicity was(More)
Nephroblastoma or embryonal nephroma is a renal tumor that is rarely seen in chickens older than 5 weeks. Avian leukosis viruses may cause nephroblastoma in the fowl. The carcass of a 2-year-old native fowl was referred for post-mortem examination. There was a large and cystic mass in the abdominal cavity. Based on the histopathological findings, the mass(More)
Chronic cerebral hypoperfusion produces brain ischemia and is associated with related memory impairment. In this study, we prepared crocetin from crocin (the main water soluble pigment in saffron stigmas) in an acidic hydrolysis and its purity was evaluated using spectrophotometry, thin layer chromatography (TLC) and high performance liquid chromatography(More)
Onion (Allium cepa) toxicosis was diagnosed in a flock of local breed sheep, which had grazed daily on onion fields for 1 month. Two ewes died, four aborted and many showed clinical signs of toxicosis including pale mucous membranes, weakness and poor appetite. Haematology of 12 ewes revealed low PCV, erythrocyte number and haemoglobin, Heinz bodies in(More)
Eighteen young native male and female goats were divided into 3 equal groups. Kerosene was given to Groups 1, 2 and 3 as single doses of 10, 20 or 40 ml/kg bw respectively. Clinical signs In-Group 1 were mild behavioral changes and in Group 2 were mild to moderate bloat, coughing and behavioral changes. None of the goats of Groups 1 and 2 died. Goats of(More)
Toxoplasma gondii, an obligatory intracellular protozoan parasite, is one of the causative agents of ovine abortion, as reported in many countries. Different techniques are being used to detect this pathogen in infected ovine fetuses. One of the most sensitive and specific diagnostic techniques is Nested-PCR amplification of the B1 target gene of the(More)
