Then hybridization in situ with hypersensitive Bcl 2 RNA probe was used to detect the change of Bcl 2 mRNA. Results The transcription of Bcl 2 gene in spermatogenic cells was obviously inhibited in the vasoligation group compared with that in the control group (P<0.05), and the transcription in the vasostomy group showed no difference from that of the control group. Conclusion Bcl 2 gene has an anti apoptotic effect in rats with vasostomy, and there was a transcriptional regulation of Bcl 2 gene in rat spermatogenic cell during the period of pre vasoligation to post vasoligation and to post vasosotomy.展开更多
