Abstract:
The relationship between the inhibitory effect of tetrandrine ( Tet ) on neutrophil ( Nen ) lysomal enzyme ( ?-glu-curonidasc , P-G ) release & calcium ion were studied. It was found that calcium ion added to the medium increased p-G release from Neu During incubation. After intracellular calcium was depleted by EGTA, P-G release was signifcantly decreased. While calcium was added, increase in P-G release reappeared. It indicated that both intracellular & extracellular calcium may be involved in P-G release. Tet & v erapamil ( Ver ) not only inhibited ?-G release induced either by calcium or serum opsonized zymOsan, but also inhibited potential operated channel of Neu. It was concludted that the inhibitory effect of Tet on Neu lysomal enzyme release was concerned with its calcium antagonism.
