动物实验和临床试用表明,棉酚是一种有效的男用节育药,但有一定的毒副作用,故目前尚不能广泛应用于临床。近年来,有人指出棉酚-PVP共沉物具有高效的抑精作用。为研究不同棉酚剂型的体外抑精效果,故进行本工作。材料和方法一、所用棉酚剂型1.棉酚生理盐水混悬液。将醋酸棉酚碾成细粉后,以生理盐水配制成二种浓度的混悬液。2.棉酚CMC混悬液。将醋酸棉酚碾成细粉后,加1%CMC充分混和,配制成二种浓度的混悬液。
Animal experiments and clinical trials show that gossypol is an effective male birth control drug, but it has certain toxic and side effects, it is not yet widely used in clinical practice. In recent years, it has been pointed out that gossypol-PVP co-precipitate has an effective anti-sperm effect. In order to study different gossypol dosage inhibitory effect in vitro, so this work. Materials and methods First, the gossypol type used 1. Gossypol physiological saline suspension. The gossypol acetate crushed into fine powder, formulated with saline into two concentrations of the suspension. Gossypol CMC suspension. Gossypol acetate grind into fine powder, add 1% CMC fully mixed to prepare two concentrations of the suspension.
