Ⅳ—3结晶系由细叶小叶(Berberis P-oiretii Schn)中提出的一种生物碱。据我室研究证明,Ⅳ—3结晶对小白鼠有明显的耐缺氧和增加心肌对86铷和131铯的摄取作用。本文研究其对离体豚鼠心房收缩力的影响,并初步探讨其对心房影响的作用机理。
The IV-3 crystal is an alkaloid proposed by Berberis P-oireti Schn. According to our laboratory studies, IV-3 crystals have a significant tolerance to hypoxia and increased myocardial uptake of 86- and 131-phr. This study was to investigate the effect of atrial contractile force on guinea pigs in vitro and to explore its mechanism of action on the atria.
