通过不同程度的细胞稀释，测定了紫球海胆和海胆精子的3‘，5’-单磷酸腺苷(CAMP)水平和呼吸速率。稀释黑线姬松茸精子可使精子cAMP水平和呼吸频率显著增加。与白花蛇舌草精子相比，紫花蛇舌草精子的稀释度仅使cAMP水平和呼吸频率略有升高。这些结果为海胆精子内源性cAMP水平和呼吸频率之间的正相关提供了证据。
The adenosine 3'',5''-monophosphate (cyclic[c]AMP) levels and respiration rates of Strongylocentrotus purpuratus and Lytechinus pictus sea urchin sperm were estimated after various degrees of cell dilution. Dilution of L. pictus sperm caused substantial increases in both sperm cAMP levels and respiratory rates. In contrast to L. pictus sperm, cAMP levels and respiratory rates were elevated only slightly by dilution of S. purpuratus sperm. These results provide evidence for a positive relationship between endogenous cAMP levels and respiratory rates in a urchin spermatozoa.
