Human milk contains many different components which interact locally in the gastrointestinal tract and stimulate some systemic functions. Among these substances are prostaglandins. We obtained samples of foremilk and hindmilk in 8 lactating women by manual expression before and after 9 a.m. and 9 p.m. on the 3rd day post partum. The following values were found for prostaglandin E2: foremilk, 162 +/- 135 pg/ml; hindmilk, 198 +/- 148 pg/ml. The values for 6-ketoprostaglandin F1 alpha were: foremilk, 818 +/- 386 pg/ml, and hindmilk, 795 +/- 487 pg/ml. The values for thromboxane B2 were: foremilk, 3,557 +/- 2,770 pg/ml and hindmilk, 4,476 +/- 4,053 pg/ml. The results showed a great variability without statistical differences between paired values of the four groups. This dispersion may be produced by the procedure for extraction and by individual basal levels.
人乳含有许多不同成分，这些成分在胃肠道局部相互作用，并刺激一些全身性功能。前列腺素就是其中的物质之一。我们在产后第3天上午9点和晚上9点前后，通过手工挤奶的方式，从8名哺乳期妇女身上获取了前奶和后奶样本。前列腺素E2的以下数值被测得：前奶，162±135皮克/毫升；后奶，198±148皮克/毫升。6-酮前列腺素F1α的数值为：前奶，818±386皮克/毫升，后奶，795±487皮克/毫升。血栓素B2的数值为：前奶，3557±2770皮克/毫升，后奶，4476±4053皮克/毫升。结果显示，四组配对值之间存在很大变异性，但无统计学差异。这种离散可能是由提取过程和个体基础水平造成的。
