Abstract:
Objective To observe the toxicity of fangyouling after one month’s transdermal administration in rabbits and evaluate its security. Methods Forty rabbits were randomly divided into 4 groups including a control group and low,middle and high dose groups of fangyouling. The rabbits in the control group were administered with sunflower oil,and the other rabbits were administrated dermally with fangyouling of 50,300 and 2 000 mg/kg respectively once a day for 4 weeks. The general con?dition,the skin irritation reaction,body weight,food consumption,hematology,blood biochemistry,organ coefficients and his?topathological changes of all the rabbits were observed. Results There was no obvious effect on the general condition in all the rabbits. However,the mild skin irritation was observed in 2 rabbits of the middle dose group and 4 rabbits of the high?dose group. The decreases of body weight and food consumption were noted in the high dose group. No changes were detected of hema?tology,blood biochemistry or viscera pathological at all dose levels. Conclusion The dose of non?toxic response of fangyouling is 50 mg/kg at this study condition.
