Abstract
Spermatozoa obtained from rabbit ejaculate were analyzed for the presence of platelet-activating factor [PAF; 1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine (AGEPC)] by using standard HPLC and TLC procedures. Fractions corresponding to synthetic PAF (AGEPC) revealed PAF-like activity amounting to 0.35 +/- 0.06 pmol/10(8) cells (mean +/- SE) as determined by bioassays based on the release of [3H]serotonin from washed rabbit platelets. This activity was lost upon base-catalyzed methanolysis, but was restored to the original level after reacetylation. Analysis of the phosphatidylcholine (PC) fraction by GC-MS subsequent to base-catalyzed methanolysis showed that 1-O-alkyl-2-acylphosphocholine comprises about 12% of the PC fraction with alkyl chain lengths of 16:0 (88%) and 18:0 (12%).Entities:
