抗菌消炎片对大鼠长期毒性的研究

目的:研究抗菌消炎片对大鼠的长期毒性。方法:将抗菌消炎片分别以30、15、7.6g(药材).kg-1.d-1(分别相当于临床日剂量0.2g(药材).kg-1.d-1的150、75、38倍)的剂量对大鼠灌胃,给药12周,停药后观察2周。分别测量大鼠体重,计算脏器系数,测定血液学和血液生化学指标,并作组织病理学检查。结果:抗菌消炎片给药组大鼠的外观体征、行为活动、体重、脏器系数、血液学和血液生化学指标与正常对照组比较,均无显著性差异;病理检查未见与药物毒性相关的显著病变,停药后也未见药物延迟性毒性反应。结论:抗菌消炎片长期用药对大鼠无明显毒性,推论临床拟用剂量应是安全的。

Long-term Toxicity of Kangjun Xiaoyan Tablets in Rats

OBJECTIVE:To observe the long-term toxicity of Kangjun xiaoyan tablets in rats.METHODS:Rats were treated with Kangjun xiaoyan tablets at doses of 30,15,and 7.6 g·kg-1·d-1(150,75 and 38 times of clinic daily dose 0.2 g·kg-1·d-1) for 12 weeks.Parameters including body weight,organ index,the indexes of haematology and biochemistry were obtained,and histopathological examination was performed.RESULTS:There were no significant differences between Kangjun xiaoyan tablets-treated group and normal control group in appearance and behavior,body weight,organ coefficient,the indexes of haematology and biochemistry.No significant pathological changes related to drug toxicity in the pathological examination nor the delayed toxicity reaction was noted.CONCLUSION:Long-term administration of Kangjun xiaoyan tablets exhibited no overt toxicity in rats,suggesting the safety of the clinical intended dosage.
