对曾接受输卵管硅橡胶塞绝育术的家兔输卵管组织，在堵塞期和取塞后的恢复期应用活体组织解剖、组织学、组织化学（Ｐ．Ａ．Ｓ反应）等方法进行观察．结果发现，堵塞期输卵管组织的粘膜层的萎缩性退变是显著的，平滑肌层受累较轻；而在取塞后的恢复期，输卵管组织基本上恢复正常．本实验证明了可复性输卵管硅橡胶塞绝育术是安全的，可复的． The tubal tissues of rabbits, who had received tubal silicone rubber plug sterilization, were observed by living tissue dissection, histology and histochemistry (P.A.S reaction) during the recovery and post-occlusion period. The results showed that the atrophic degeneration of the mucosal layer of the tubal tissue during occlusion was significant and the involvement of the smooth muscle layer was mild. In the convalescent period after retrieval, the tubal tissues returned to normal. This experiment proved that the silicone tube can be repaired tubal sterilization is safe and can be complex.
