title: [Species differences in subacute toxicity of pyrrole aldehyde N4-(4-methoxyphenyl) semicarbazone].
abstract: The subacute toxicity of compound 1 was investigated in rats and dogs. Compound 1 was administered orally to rats of both sexes at daily doses of 0.5, 1.0 or 2.5 g/kg for 3 months. No change attributable to the administration of compound 1 was found either in blood count or in histopathological examination. Decreases in SGPT, alkaline phosphatase and lactic acid dehydrogenase and an increase in serum cholesterol were detected. Compound 1 was mixed with food and given to dogs of both sexes daily at doses of 0.2 or 0.5 g/kg for 3 months. Severe toxic symptoms including anorexia, emesis, ataxia and convulsive seizures were observed. A decrease in SGPT and increase in alkaline phosphatase were also detected. Hyperemia of the duodenal mucosa and severe kidney lesions were found in histopathological examination. Neither abnormality of appearance nor histopathological change was found in a pig receiving compound 1 at the daily dose of 0.1 g/kg for 3 months. The results suggest that there are differences of compound 1 metabolism among the species used in this study.
