Abstract

Bretylium reduced the content of endogenous and newly-synthesized noradrenaline (NA) and also reduced the specific activity of NA in the microsomal fraction of rat heart. Bretylium also decreased the endogenous NA content of the microsomal subfraction which equilibrated in the 0.7 M sucrose region of a density gradient; it was without effect on the NA content of other subfractions.

摘要

溴苄铵降低了内源性和新合成的去甲肾上腺素(NA)的含量,同时也降低了大鼠心脏微粒体部分中NA的比活性。溴苄铵还降低了在密度梯度的0.7M蔗糖区域达到平衡的微粒体亚组分的内源性NA含量;它对其他亚组分的NA含量没有影响。
