摘要
试验以华南主要野生蔬菜守宫木为材料,对其毒理学进行了探讨.结果表明:小鼠经口服LD50大于10.00 g.kg-1;守宫木引起小白鼠的精子畸形率增多;守宫木30 d喂养对SD大白鼠的肝、肾、脾、心、肺、睾丸等器官有损伤,且组间差异显著,呈一定的剂量反映关系,试验表明30 d喂养守宫木最大无作用剂量组应小于2.5 g.kg-1.说明守宫木可能具有蓄积毒性,不适宜作为蔬菜长期日常食用.
The toxicity of Sauropus androgynus, a wild vegetable in South China, was investigated in this study. It was shown that the LD50 for mice was higher than 10.00 g · kg^-1 and an increase of sperm abnormality was observed in mice. The 30 d feeding test showed that S. androgynus could damage liver, kidney, spleen, heart, lung and testis of the mice. The damage became severer with the increase of dose. In 30 d feeding with S. androgynus, the maximal inactive dose group was less than 2.5 g · kg^-1, indicating that it is possible that S. androgynus has an accumulative toxicity, and is not suitable for human and animal consumption.
