Activation of sea urchin eggs by sperm or melittin, a main component of bee venom, causes a burst of respiration in the eggs. In order to know the mechanism of the respiratory burst which was insensitive to cyanide, the effect of indomethacin and aspirin, inhibitors of fatty acid cyclooxygenase, was examined on the respiration of eggs of Hemicentrotus pulcherrimus. Indomethacin (330 μM) inhibited the respiration of the egg activated by melittin or by fertilization. Aspirin inhibited the melittin-activated respiration. Phenidone which inhibits cyclo-oxigenase and lipoxygenase, seemed to inhibit the melittin-activated respiration, although oxygen uptake due to autooxidation of the compound in sea water made the quantitative evaluation difficult. Since common property of these anti-inflammatory compounds is the inhibition of fatty acid cyclo-oxygenase, the present results indicate the participation of metabolism of poly-unsaturated fatty acids, such as arachidonic acid, in the respiratory burst caused by fertilization or by melittin.
