Serum oxytocic and oxytocinase activities were examined in 50 females with normal pregnancy and 50 with threatened abortion by using biological (oxytocin) and biochemical (oxytocinase) methods. The findings suggest that there is no regular changes in serum oxytocic activity in the course of pregnancy, whereas its oxytocinase activity significantly increases with pregnancy development. The females with threatened abortion showed the same values of serum oxytocic activity as those with normal pregnancy, but much lower oxytocinase activity. The assay of serum oxytocinase activity may be of diagnostic value when threatened abortion is suspected.
采用生物学（催产素）和生物化学（催产素酶）方法，对50例正常妊娠女性和50例先兆流产女性的血清催产活性和催产素酶活性进行了检测。研究结果表明，在妊娠过程中血清催产活性无规律变化，而其催产素酶活性随妊娠进展显著增加。先兆流产女性的血清催产活性与正常妊娠女性相同，但催产素酶活性低得多。当怀疑为先兆流产时，血清催产素酶活性检测可能具有诊断价值。
