Abstract

The effect of the commercial lectin (Con A, PHA, SRA, WGA and UEA) as well as of the prepared by us extract from roots of Arum maculatum (Am and AM 80 degrees C) was studied on migration of human spermatozoa in bovine estrous cervical mucus, using the capillary sperm penetration test of Kremmer. It was established that Con A, PHA and AM inhibited the migration of spermatozoa in a concentration, in which they agglutinated human spermatozoa in vitro. Nonagglutinating human spermatozoa SBA and AM 80 degrees C inhibited also the migration of spermatozoa in the mucus.

[毛细管精子渗透试验中凝集素对人精子的影响]。
采用Kremmer毛细管精子渗透试验,研究了商业凝集素(Con A、PHA、SRA、WGA和UEA)和我们所制备的Arum maculatum根提取物(Am和Am 80℃)对人精子在牛发情宫颈粘液中迁移的影响。证实了Con A、PHA和AM在一定浓度下对精子的迁移有抑制作用,在一定浓度下能凝集体外的人精子。不凝集的人精子SBA和am80℃也能抑制精子在黏液中的迁移。
