Demonstration of a phospholipase A2 inhibitor in human plasma and in plasma from the European hedgehog (Erinaceus europaeus).
1. Endogenous phospholipase A2 (PLA2) inhibitors in human plasma and in plasma from the hedgehog (Erinaceus europaeus) were demonstrated. 2. The PLA2 activity increased 45-fold in human plasma when a PLA2 binding factor was removed. Furthermore, two peaks of PLA2 inhibitory activity were found after DEAE-chromatography. 3. High levels of PLA2 inhibitory activity was found in plasma from the European hedgehog, E. europaeus. 4. The molecular weight was estimated to 140,000. 5. On DEAE-chromatography two peaks were found which were chromatographically similar to the PLA2 inhibitors in human plasma.
