An interview guide entitled,"Maternal Perception of the Onset of Lactation" was also used to obtain milk secretion data. The analytical results revealed a mean onset of lactation of 75.7±16.8 hours (range=40 to 117). The prevalence of delayed lactation onset was 50.5%(n=58); 64.3%(n=42) were primiparous, and 41.9%(n=74) were multiparous. Parity, hours of withholding oral intake post-operation, and use of formula were significant predictors of perceived lactation onset. These factors explained 22.5% of perceived lactation onset in postpartum women who planned cesarean section.
研究结果发现:(1)泌乳起始时间的平均值为757±168小时(范围40至117小时);(2)产妇自觉延迟泌乳的发生机率为500%(n=58),其中延迟泌乳的初产妇有27位,占所有初产妇(n=42)的64.3%,延迟泌乳的经产妇有31位,占所有经产妇(n=74)的41.9%,经产妇发生延迟泌乳的机率较低;(3)产次、术后禁食时间以及配方乳使用,是泌乳起始时间的重要预测因子,共可解释计画剖腹产妇泌乳起始时间总变异数的22.5%。

An interview guide, entitled "Maternal Perception of the Onset of Lactation", was also used to obtain milk secretion data. Results found a mean onset of lactation of 78.2±18.7 hours (range=42 to 121 hours). The prevalence of delayed lactation onset was 43.6%(n=58). Slighly over half of participants (56.9%, n=33) were primiparous. Parity, total second stage of labor duration, duration of second labor stage beyond one hour, and perinea wound pain were the most significant predictors of delayed lactation onset.

We have synthesized 4,4'-dinitro-3 4''-dimethyl triphenylamine,(1), in 84% yield in an one-step condensation process between 3,4-dimethyl aniline and 4-fluoro-nitrobenzene. After the auto-oxidation of (1) and the subsequent hydrogenation of the nitro-groups, an AB2 type triphenylamine polyimide intermediate bearing two amine groups and one acid-anhydride group each on individual phenyl ring,{AB2 PI Intermediate}, was prepared successfully. The yields of the autoxidation and the hydrogenation steps are 81% and 90% respectively.
