Toxicological evaluation of acute and sub-chronic ingestion of hydroalcoholic extract of Solanum cernuum Vell. in mice.

Abstract：

ETHNOPHARMACOLOGICAL RELEVANCE:Solanum cernuum Vellozo is a Brazilian shrub or small tree, restricted to Southwest states of the country. It has been widely used for the treatment of many ailments. The pharmacological activity of the extract on gastric ulcer has been the major therapeutic target proposed by the population investigated. MATERIALS AND METHODS:In the acute toxicity test was used increasing doses of the extract (2, 4, 8, 12, 16, 20 and 25 g of extract per kilogram of body weight). The animal behavior was observed from 5h after a single administration of the extract and subsequently monitored daily until the fourteenth day, beyond the calculation of the estimated LD50 of the extract. In the test sub-chronic toxicity was used two doses of the extract (0.1 and 1.4 g/kg) and the parameters analyzed over 31 days were: body weight, food intake, behavior, respiratory rate, movement and mortality of animals. After anesthesia, blood samples were collected for hematological and biochemical analysis. The animals were euthanized followed by macroscopic analysis of the stomach and intestine. Liver, lungs and kidneys were removed, weighed and analyzed histopathologically. RESULTS:In the acute toxicity test was observed a dose-dependent mortality and the value of estimated LD50 was 14.50 g/kg. In the hematological and biochemical analyses there were significant increase in the activities of AST and ALT indicating liver toxicity, but the extract was not able to alter food intake, body weight and organ weights after 31 days of treatment and it did not produce significant histopathological changes. CONCLUSION:Therefore we can consider the hydroalcoholic extract of Solanum cernuum Vell as practically non-toxic in acute administration and safe in the sub-chronic administration, as hepatotoxicity was observed only with the highest dose used, not with the dose routinely used by the native population.
