Abstract
The effect of bunaphtine (BNA, 5 X 10(-5)M) on La3+ -resistant 45Ca content and 45Ca efflux was studied on rat aortic smooth muscle. BNA decreased both control and norepinephrine-stimulated La3+-resistant 45Ca content and increased the 45Ca efflux. These effects could explain the inhibition of the contractile responses induced by BNA.
摘要
研究了布那唑嗪（BNA，5×10⁻⁵M）对大鼠主动脉平滑肌中镧离子抗性⁴⁵Ca含量和⁴⁵Ca外流的影响。BNA降低了对照和去甲肾上腺素刺激下的镧离子抗性⁴⁵Ca含量，并增加了⁴⁵Ca外流。这些作用可以解释BNA对收缩反应的抑制作用。
