  • Title: [Effect of tetracaine on thrombocyte aggregation and mobilization of the intracellular calcium].
    Author: Borin ML, Azizova OA, Khodorov BI.
    Journal: Ukr Biokhim Zh (1978); 1988; 60(3):56-60. PubMed ID: 3137702.
    Abstract:
    Tetracaine (1 mM), a local anesthetics, lowers a degree of aggregation of human thrombocytes which is induced by thrombin (0.15 u/ml) and suppresses its appearance. Aggregation of thrombocytes induced by phorbol ester, TPA (10-8 M), an activator of protein kinase C, is inhibited completely by the mentioned doses of the anesthetics. In the presence of tetracaine the release of intracellular Ca is lower to some extent, but then it surpasses the control level. It is established that under the action of ionophore A23187 tetracaine exerts no effect on mobilization of intracellular Ca2+.
