目的观察氰胺化钙(荣宝)作用于钉螺引起的组织学改变,探讨其杀螺机理.方法经氰胺化钙浸提液处理,在不同时间取钉螺进行固定并行病理切片,分析杀螺剂对钉螺的组织学影响.结果经氰胺化钙浸提液处理48 h后钉螺外套膜上皮细胞、呼吸系统鳃条的上皮细胞、肝细胞、腹足的肌细胞等都受到严重损伤,直接导致钉螺的死亡.48 h钉螺死亡率96.70%,72 h达100%.结论荣宝对钉螺多个组织均有损害,为一种有效的杀螺剂.

Objective To observe the effects of calcium cyanamide (Rongbao) on the histological and morphological changes of Oncomelania hupensis snails in order to explore its molluscicidal mechanisms.Methods The serial snails' slides were fixed after soaking in a concentration of Rongbao leached liquor at different time.The histological and morphological changes of the snails were compared among these slides.Results After soaking in the Rongbao leached liquor for 48 h,the mantle epithelia,respiratory epithelia of the gill,liver cells,and muscle cells of gastropods were injured seriously,which resulted in the death of the snails directly.The death rates of the snails were 96.70% and 100% after soaking in the Rongbao leached liquor for 48 h and 72 h,respectively.Conclusion Rongbao is an effective molluscicide by damaging the several snail tissues.
