Abstract
A marked reduction (80.8%) in the zinc uptake by boar spermatozoa cooled to 4 degrees C occurs when the seminal plasma is pretreated with egg yolk-glucose at this temperature. Crude lecithin is less effective (59.8%). Similar pretreatment of the seminal plasma by the polycationic drug Antrypol, which totally removes the zinc-precipitable basic haemagglutinin, does not result in a significant reduction of the sperm zinc uptake at 4 degrees C.
摘要
当精浆在4℃下用蛋黄 - 葡萄糖预处理时，冷却至4℃的公猪精子对锌的摄取量显著降低（80.8%）。粗卵磷脂的效果较差（59.8%）。用多阳离子药物安曲波进行类似的精浆预处理，该药物可完全去除可沉淀锌的碱性血凝素，但在4℃时不会导致精子锌摄取量显著降低。
