Abstract
Field stimulation of isolated, spirally-cut cervix from day-22 pregnant rats produced contractions which could be inhibited by tetrodotoxin or hyoscine and potentiated by propranolol. The rat cervix would appear to receive both cholinergic and noradrenergic innervations whose transmitters activate muscarinic cholinoceptors and beta-adrenoceptors respectively.
摘要
对妊娠22天大鼠的离体螺旋形子宫颈进行场刺激，可引起子宫收缩，这种收缩可被河豚毒素或东莨菪碱抑制，被普萘洛尔增强。大鼠子宫颈似乎接受胆碱能和去甲肾上腺素能神经支配，其递质分别激活毒蕈碱型胆碱能受体和β-肾上腺素能受体。
