本文旨在研究各种前列腺素(PGs)和肾上腺素受体激动剂和拮抗剂对足月宫颈平滑肌的影响。试验对象为64例孕37~40周决定行剖腹产的孕妇(年龄21~41岁,平均29.9岁)。在常规或硬膜外麻醉下手术,自宫颈前唇中部取活检标本立即投入净Krebs-Binger碳酸氢钠缓冲液中,每一肌条分别安装于有缓冲液的组织槽中。等处理后给予下述药物试验:PGE_2、PGF_(2α)、6-酮-PCF_(1α)、PGI_2、甘碳(5、8、11、14)四炔酸(ETYA)、去甲肾上腺素(NA)、苯氧麻黄硷(phenylephrine)、
This article aims to investigate the effects of various prostaglandins (PGs) and adrenergic receptor agonists and antagonists on term cervical smooth muscle. The subjects were 64 pregnant women who were scheduled for caesarean section at 37-40 weeks (range, 21-41 years, average 29.9 years). Surgery under conventional or epidural anesthesia, biopsy specimens taken from the anterior cervix lip immediately into the net Krebs-Binger sodium bicarbonate buffer, each strip was installed in the buffer tissue tank. After treatment, the following drug tests were given: PGE 2, PGF 2α, 6-keto-PCF 1α, PGI 2, glyceryl 5,8,11,14 tetrahyneoic acid (ETYA), norepinephrine NA), phenylephrine,
