The authors have studied the total lipids, triglycerides and cholesterol in the milk of 30 mothers over a lactation period of 4 days to 10 months. The total lipids showed diurnal oscillations with a minimal level in the morning and maximal level (P less than 0.001) at 1 p.m. and a slight decrease in the evening, without reaching the levels found in the morning. The lipid concentration in the milk decreases after 4 months of lactation. The oscillations of the lipids take place on the expense of the triglyceride content (r = 0.99). Cholesterol represented on the average 1.54% of the lipid content, showed a maximum level at a month and decreased after 6 months of lactation. The dynamics of lipid composition of the human milk suggests a physiologic significance in the development of the infant.
作者研究了30位母亲在4天至10个月哺乳期内乳汁中的总脂质、甘油三酯和胆固醇。总脂质呈现昼夜波动，早晨水平最低，下午1点达到最高水平（P小于0.001），晚上略有下降，但未降至早晨的水平。哺乳期4个月后乳汁中的脂质浓度降低。脂质的波动是以甘油三酯含量为代价发生的（r = 0.99）。胆固醇平均占脂质含量的1.54%，在1个月时达到最高水平，哺乳期6个月后下降。人乳脂质组成的动态变化表明其在婴儿发育中具有生理意义。
