Serum cystine-animo-peptidase (CAP) is a valid test for placental function. We found it interesting following up the variations of CAP during induced labour and early puerperium; with this aim in view we determined the values of the enzyme in 33 pregnant nullipares. Six blood samples were taken from each woman. (174 determinations in all): 1) before labour; 2) at 5 cm. dilatation of the uterine neck; 3) immediately after the expulsion of fetus; 4) two hours after delivery; 5) first day of puerperium; 6) in the fourth day of puerperium. Statistical analysis -- Wilcoxon's test and rank bivalent variants analysis of Friedman (X2r) -- show that the variations of values in the first four groups are not statistically significant; values from 1th and 4th day of puerperium show a mean reduction in level of CAP which is remarkable and statistically significant.
血清胱氨酸氨基肽酶（CAP）是一种评估胎盘功能的有效检测方法。我们发现，在引产和产褥早期追踪CAP的变化很有意思；出于这个目的，我们测定了33例初产妇在孕期的该酶值。每位女性采集6份血样（共174次测定）：1）临产前；2）宫颈口扩张5厘米时；3）胎儿娩出后立即采集；4）分娩后两小时；5）产褥期第一天；6）产褥期第四天。统计分析——威尔科克森检验和弗里德曼秩二价变量分析（X2r）——表明，前四组数值的变化无统计学意义；产褥期第一天和第四天的CAP值平均水平出现显著且有统计学意义的降低。
