In 29 normotensive nonpregnant women, the circadian rhythm of the colloid-osmotic (oncotic) pressure (COP) was estimated. On average the COP was 25.3 mmHg (3.34 kPa). Around this value (= 100%) the daily oscillation was 13.5% with an interindividual variation of between 28.1 and 4.3%. A stable sinusoidal daily rhythm occurred with the lowest values in the night and the highest values in the afternoon. Changes in arterial blood pressure and of the permeability of capillaries depending on the time of day are discussed as the main reason for this circadian rhythm. For COP estimations in clinical routine proofs should be taken at about 8.00 a.m. since these values correspond most closely to the daily average.
在29名血压正常的非妊娠女性中，对胶体渗透压（COP）的昼夜节律进行了评估。平均COP为25.3 mmHg（3.34 kPa）。以该值（= 100%）为基准，每日波动为13.5%，个体间差异在28.1%至4.3%之间。出现了稳定的正弦形昼夜节律，夜间值最低，下午值最高。讨论了动脉血压和毛细血管通透性随一天中时间的变化，认为这是这种昼夜节律的主要原因。在临床常规中进行COP评估时，应在上午8点左右进行检测，因为这些值与每日平均值最为接近。
