摘要

Platelet activating factor (PAF) plays an important role in mammalian reproduction. The aim of this study was to investigate the effects of PAF on capacitation and acrosome reaction of mouse spermatozoa by chlortetracycline (CTC) fluorescence assayand coomassie blue staining. The percentage of capacitated mouse spermatozoa was increased (P<0.05) by incubation with 50 ng/ml PAF for 20-120 min. The peak response occurred between 80 to 100 min of exposure to PAF. The effects of PAF on acrosome reaction may be not receptor-mediated since the biologically inactive form of PAF, lyso-PAF, had the same effects. Ionophore A23187 stimulated an increase in acrosome-reactions of PAF-treated spermatozoa, but not of lyso-PAF-treated ones. These results suggestthat PAF mainly acts on sperm capacitation.
