本文叙述了一种简易的肾组织比重测定方法。用本方法测定了正常肾组织及左肾动脉注射油酸后肾皮质和髓质的比重,结果表明,正常肾髓质的比重明显低于皮质,较低剂量油酸可引起皮质比重降低,油酸剂量加大,肾髓质的比重也降低。本方法简单可靠,可用于大小动物的实验研究。 This article describes a simple method for the determination of the proportion of kidney tissue. The method was used to determine the proportion of renal cortex and medulla in normal renal tissue and left renal artery after injection of oleic acid. The results showed that the proportion of normal renal medulla was significantly lower than that of cortex, and the lower dose of oleic acid could cause the decrease of cortical weight. Acid dose increased, the proportion of renal medulla also decreased. The method is simple and reliable and can be used for experimental research on large and small animals.
