本文就产科老药新用作一综述。 1 心痛啶(NF)抑制早产和治疗痛经子宫肌细胞浆内游离钙浓度主要受细胞外钙池和细胞和细胞内钙库的调节。NF能阻滞经膜转运的Ca~(2+)流动,既可阻止钙从细胞外钙池进入胞浆,又可阻止细胞内钙库的钙释放。国内报道,NF治疗16例先兆早产孕妇,延长分娩时间达29.4±10.5天,延长妊娠3周以上者87.5％。NF还能有效地 This article is a new review of obstetrics and gynecology. 1 Cardiac pain (NF) inhibition of preterm labor and treatment of dysmenorrhea intramyocardial plasma intracellular free calcium concentration mainly by the extracellular and intracellular calcium cells and the regulation of cells. NF can block the transport of Ca ~ (2+) through the membrane, which can prevent calcium from entering the extracellular matrix into the cytoplasm, but also to prevent calcium release from the intracellular calcium store. Domestic reports, NF treatment of 16 cases of threatened premature delivery of pregnant women, prolonged delivery time of 29.4 ± 10.5 days, prolonged pregnancy more than 3 weeks 87.5%. NF can also be effective
