本文观察了42例健康老年人25小时禁水试验前后尿液渗透压变化。结果发现,禁水时间与尿液渗透压呈正相关15例,负相关6例,无相关21例;≥60岁、≥70岁及男性禁水时间与尿液渗透压无相关关系,而女性则呈正相关;不同性别、年龄或类型之间最高尿液渗透压差别无显著性。本文对上述现象的机理及意义进行了初步探讨。
In this paper, the changes of urine osmotic pressure before and after the 25-hour water-free test in 42 healthy elderly were observed. The results showed that there was a positive correlation between water forbidden time and urine osmotic pressure in 15 cases, negative correlation in 6 cases and no correlation in 21 cases. The age≥60 years, ≥70 years and male water-time were not correlated with urine osmotic pressure. There was no significant difference in the highest urine osmotic pressure among different sexes, ages or types. This article has carried on the preliminary discussion to the mechanism and the significance of the above phenomenon.
