Experimental Study on the Safety of Nostoc commune Vauch Cream

目的评价地木耳乳膏皮肤用药的安全性。方法采用家兔完整皮肤和破损皮肤分组涂抹地木耳乳膏(1.0g/只)和空白基质(1.0g/只)进行皮肤刺激性实验;健康豚鼠分组涂抹地木耳乳膏(0.2g/只)、空白基质(0.2g/只)、1%2,4-二硝基氯苯溶液(0.2mL/只)进行致敏性实验,均以红斑和水肿情况为评价标准;对大鼠分组涂抹地木耳乳膏(1g/只)、空白基质(1g/只)和1%2,4-二硝基氯苯溶液(1mL/只)进行皮肤急性毒性实验,观察各组大鼠体质量变化、死亡及中毒反应等。结果地木耳乳膏对家兔完整皮肤无刺激性,对破损皮肤有轻度刺激性,给药48h后刺激性消失;对豚鼠无过敏反应和急性毒性反应。结论地木耳乳膏是一种安全性较好的外用制剂。
