摘　　要：生物节律特别是昼夜节律起搏系统的细胞与分子生物学基础，是目前时间生物学研究中的重要课题。一般认为生物体内的昼夜起搏系统由起搏器及其传入通路和传出通路三部分组成。近来的研究，揭示了海兔和枣螺视网膜中的昼夜起搏细胞及其电生理学特性与传入通路的分子基础；在酵母菌、红色链孢霉等上的研究，则指出Ｃａ＾２＋、ｃＡＭＰ、ｃＧＭＰ在生物昼夜起搏系统的上述三部分具有重要作用。The cellular and molercular biology bases of chronobiology was present study importent subject.A biological circadian pacemaker system can be regarded as having three general components:pacemaker with its input pathway and output pathway.The present stuies proved circadian pacemaker cell and its electrophysiology characters of the Aplysia and Bulla retiral.Most recently results have been observed in yeast saccharomyces cerevisiaea and neurospora crassa et al.which showed the important effct of the Ca2+.cAMP.cGMP et al.on the biological circadian pacemaker and input pathway.output pathway.
