PRELIMINARY STUDY ON NK ACTIVITY INHIBITION BY HUMAN SEMINAL PLASMA AND MICE SPLEEN / 中国免疫学杂志

ABSTRACT

In this paper,immunosuppression ofNK activity induced by(1)Human se-minal Plasma(HSP)and its Fraction-1 on sephadex G-100 in vitro;(2)in-travenous injection of HSP,Fraction-1 or mice sperm and(3)uptake of HSP,Fraction-1 or,mice sperm via rectalroute were studied.It has been pro-ved by our experiment that HSP,Fraction-1 and mice sperm possesspotent immunosuppressive effect interm of NK activity inhibition.Ascompared with intravenous injection,the immunosuppression induced byrectal exposure of HSP,Fraction-1or mice sperm is much stronger
