摘要
为观察14周龄雄性昆明种小白鼠施行颌小腺摘除后1~6周附睾内成熟精子数量的变化,取小鼠48只,随机分成12组,其中6组行颌下腺摘除手术,其余为对照。结果表明,颌下腺摘除后第4周开始,附睾内精子数量呈显著减少趋势,第5和第6周的精子数分别为0.56±0.26×107和0.50±0.13×107,与对照相比分别有显著差异(P<0.05)和非常显著差异(P<0.01)。摘除颌下腺手术后5周内小鼠的体重与对照相比无显著变化,但第6周的体重下降有明显的统计学差异(P<0.01)。
Sialoadenectomy was employed to study the effects of the submaxillary glands on the sperm numbers of the epididymis in mice.48 male Kunming albino mice(14 week old) were randomly divided into 12 groups.The removal of the submaxillary glands was conducted among six groups(4 mice per group).The control that was age and weight matched six groups(4 mice each group) male mice had received sham operation.The epididymis sperms were counted each week after the operation.By 5 and 6 weeks after the sialoadenectomy, numbers of mature sperm in the epididymis were 0 56±0 26×10 7 and 0 50±0 13×10 7,respectively,and decreased 50 percent( P <0 01).The body weight in sialoadenectomized mice was also somewhat less than that of control.Results showed that the submaxillary glands might be related with spermatogenesis in mice.
