The percutaneous acute toxicity of Yusheng Xiaoyang Lotion was observed by one time limited dose method, and ap-parent sign changes and death condition of mice after administration of the drug were recorded. After the test, all the animals were weighed and subjected to gross anatomy, and if there were abnormal phenomena, further histopathological examina-tion of should be done. Animals died during the test should be subjected to anato-my. [Result] All the mice survived and exhibited normal behavior,glossy hair and increase of body weight in accordance with growth law.No local and systematic toxicity responses on skin were observed. In visual observation after dissection, no pathologic changes on heart, liver, spleen, lung and kidney were observed. There were no significant differences in body weight between the Yusheng Xiaoyang Lo-tion group and the blank control group before administration,the 7th d after adminis-tration and the 14th after administration （P〉0.05）. [Conclusion] In the transdermaldrug delivery acute toxicity test of Yusheng Xiaoyang Lotion on mice, no obvious toxic responses were observed under the total dose of 89.70 g/kg （equivalent to 120 times of the clinical daily dose for adults）.展开更多
