摘要: 目的: 用生物学短期测试方法评价香烟烟雾的致畸性。方法:分别从香烟烟雾中提取水溶性和脂溶性物质,观察它们对水螅成体的毒性和对胃区体再生的抑制作用,用Wilby 评分方法计算出对成体的中效毒性浓度(T50) 和对胃区体再生抑制的中效浓度( I50) ,根据T50/ I50比值判断香烟烟雾水溶性和脂溶性提取物的致畸性。结果:香烟烟雾水溶性和脂溶性提取物的T50分别为159. 1 mg/ L 和29. 8 mg/ L ,I50分别为14. 5 mg/ L 和3. 8 mg/ L ,T50/ I50比值分别为10197 和7. 84。香烟烟雾的水溶性与脂溶性提取物均有明显的致畸作用。

Abstract: Purpose : The teratogenic potential of cigarette smoke was evaluated by using the short term biological assay. Methods : The adults and regenerators of Hydra were exposed respectively to water-soluble and fat-soluble extracts of cigarette smoke. According to Wilby’s score method , median toxic concentration (T50) in adults and median inhibition concentration ( I50) in regenerators of the extracts were calculated. On the basis of T50 to I50 ratios , the teratogenicity was judged. Results : T50 and I50 of the water-soluble and fat-soluble extracts 159. 1 mg/ L , 29. 8 mg/ L and 14. 5 mg/ L , 3.8 mg/ L , and T50 to I50 ratios were 10. 97 and 7. 84 , respectively. Conclusion : The water-soluble and fat-soluble extracts of cigarette smoke showed teratogenesis in the Hydra regeneration assay.
