Changes in the intracellular concentrations of cyclic nucleotides during the initiation of starfish sperm motility were examined. The intracellular concentration of cGMP decreased just after dilution of sperm with sea water, whereas that of cAMP increased concomitant with initiation of sperm motility. In acidic sea water, the intracellular concentration of cGMP decreased but no increase in that of cAMP was observed and sperm remained immotile. The presence of a phosphodiesterase inhibitor enhanced the rate of increase in the intracellular concentration of cAMP and the sperm motility.
These results indicate that cAMP is involved in the initiation of sperm motility in starfish. 相似文献

Effect of Prostaglandin E<Subscript>2</Subscript> and Aspirin on the Secondary Aggregation of Human Platelets 总被引:8,自引:0,他引:8
THE lack of cellular specificity1 of the prostaglandins creates potential hazards in their use as therapeutic agents: we describe one associated with PGE2 and the reversal of the effect with aspirin. 相似文献
