摘要
本文用Ｌｅｃｔｉｎ染色法、原子吸收光谱法和电化学法研究了γ－氨基丁酸对人类精子顶体反应的诱导作用，以及它对Ｎａ＋、Ｋ＋、Ｃａ２＋、Ｍｇ２＋和Ｃｌ－在顶体反应时的转运情况的影响。结果表明：１．γ－氨基丁酸可明显地诱发人精子顶体反应（Ｐ＜０．０５）。２．γ－氨基丁酸可引起Ｎａ＋、Ｃａ２＋、Ｍｇ２＋内流，Ｋ＋外流和Ｃｌ－先外流再内流。因此，γ－氨基丁酸对人精子具有调控作用。
The human sperm acrosome reaction induced by GABA and some ions in acrosome reaction were studied with the methods for lectin staining,atom absorption spectrum and electric chemistry.The results showed:1.GABA can induce human sperm acrosome reaction(P<0.05);2.in acrosome reaction GABA may cause,Na+,Ca2+ and Mg2+ influx,K+ efflux and Cl- first influx and then efflux.Therefore GABA has regulated human sperm.
