Abstract:
The toxioity of rivanol(home product)in animals was investigated according to the standard in Chinese Pharmacopoeia. Acute toxicity ,subacute toxicity and cumulative toxicity in mice,sensi-tization in guinea pigs and subchronic toxicity in dogs were tested. In acute toxicity test,the LD50 (IV)was 18. 494?2. 90mg/kg,which belonged to be a moderate toxic substances. When the dose was 1mg/kg,no toxic effect was observed in any animal. When the dose(IV)increased to 5mg/kg, mild degeneration and focal necrosis of cells,infiltration of inflammatory cells and proliferation of Kuffer'cells were shown in liver of mice while no toxic effect was observed in dogs. In cumulative toxicity test,the LD50 was 19. 3mg/kg which was more than Ld50 suggested that there was some tolerance and cumulative toxicity effect might not be present in mice. There was no sensitization showed in guinea pigs when rivanol was given via abdomenal administration.
