Abstract: Susceptibility of sheep to oral administration of Citrullus colocynthis fruits, Nerium oleander leaves or their mixture is described in 12 sheep assigned as untreated controls, C. colocynthis-treated at 0.25 g/kg/day, N. oleander-treated at 0.25 g/kg and plant mixture-treated at 0.25 g of C. colocynthis/kg plus 0.25 g of N. oleander/kg. The daily use of 0.25 g of C. colocynthis/kg for 42 days was not fatal to sheep and caused slight diarrhoea, catarrhal enteritis, centrilobular hepatocellular fatty change and degeneration of the renal tubular cells. Single oral doses of 0.25 g of N. oleander/kg were lethal to sheep within 18–24 h and caused uneasiness, grinding of the teeth, dyspnoea, anorexia, frequent urination, ruminal bloat, ataxia and recumbency before death. The main lesions were widespread congestion and haemorrhage, pulmonary cyanosis and emphysema and severe hepatonephropathy. Rapid death was also observed in sheep receiving single doses of the mixture of the two plants. Effects were correlated with changes in the activities of serum lactic dehydrogenase (LDH) and aspartate transaminase (AST) and concentrations of cholesterol, bilirubin, total protein, albumin, globulin and urea and haematological parameters.
