【摘要】 用国产利凡诺参照有关标准方法进行小鼠急性、亚急性、蓄积性毒性实验,豚鼠致敏实验及犬亚慢性毒性实验,结果表明:急性毒性实验的LD₅₀（i.v）为（18.94±2.90）mg/kg,属中等毒性物质。动物静脉连续给药（1mg/kg）2～3个月,小鼠亚急性或犬亚慢性毒性实验,均未见任何毒性作用。剂量增至9mg/kg,亦未见犬有毒性表现,仅小鼠肝组织出现轻度变性、细胞局灶性坏死、炎症细胞浸润、枯夫氏细胞增生,其余脏器未见异常。蓄积性实验结果LD₅₀为19.3mg/kg,大于LD₅₀,说明利凡诺在小鼠体内无明显蓄积作用。豚鼠腹腔给药无致敏反应。更多还原

【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.更多还原
