RESUMO
The effects of co-administration of a cassava rich diet and alcohol in rats were investigated. The animals were divided into four groups (1) Control, (2) Alcohol, (3) Cassava and (4) Alcohol + Cassava. Consumption of alcohol along with cassava reduced the alcohol induced toxicity which was evidenced by the lower activities of GOT, GPT, GGT, acid phosphatase and alkaline phosphatase in the liver and serum of co-administered group. The pyruvate content in the blood increased while the lactate content, lactate/pyruvate ratio and the activity of LDH decreased in the blood due to co-administration. The blood cyanide content, serum thiocyanate content and the activities of rhodanase and beta-glucuronidase increased on co-administration. The histopathological studies also revealed that co-administration reduced the alcohol induced toxicity.

Feeding 50% ethanolic extract of A. aspera to male rats resulted in reduced sperm counts, weight of epididymis, serum level of testosterone and testicular activity of 3beta-hydroxysteroid dehydrogenase, while motility of the sperm and activity of the HMG CoA reductase were not affected. Cholesterol level in the testis, incorporation of labelled acetate into cholesterol, 17-ketosteroids in urine and hepatic and fecal bile acids were increased. The results suggest that ethanolic extract of A. aspera caused reproductive toxicity in male rats and the action may be by suppressing the synthesis of androgen.
