[Effect of naomaitong on basilar artery rings and portal vein strips].
Both Naomaitong and single salvia miltiorrhiza inhibit the contraction of rabbit basilar artery rings evoked by CaCl2 and KC1 and have nonspecific antagonism against the quantity effect curve of CaCl2. Naomaitong and single salvia miltiorrhiza also inhibit the contraction of rabbit basilar artery rings evoked by KC1. Clearly the inhibitory function of the former is greater than that of the latter. But on the myogenic activity of portal vein strips in rats Naomaitong has light inhibitive effect while salvia miltiorrhiza has not.
