心痛定是一种钙通道阻滞剂,对平滑肌有普遍的松弛作用,推测其对胆囊收缩也有抑制作用。因此,作者采用双盲和安慰剂对照法,研究口服心痛定对人类胆囊容积和进餐引起胆囊排空的作用。材料与方法:用实时超声对12名健康志愿者作胆囊容积和胆囊收缩功能测定,每次测量均应在相同的呼吸相和探头置于同一位置进行。受试者禁食一夜后于次晨先测量首次空腹胆囊容积。然后8名受试者 Heartache is a calcium channel blocker, a general relaxation of the smooth muscle, presumably on the gallbladder contraction also inhibited. Therefore, the authors used double-blind and placebo-controlled studies to determine the effect of oral heartburn on human gallbladder volume and meal-induced gallbladder emptying. Materials and Methods: Using real-time ultrasound, we measured the volume of the gallbladder and the function of the gallbladder in 12 healthy volunteers. Each measurement should be performed in the same position with the same respiratory phase and the probe. After overnight fasting, subjects measured the first fasting gallbladder volume the next morning. Then eight subjects
