Under study were peculiar features of the structure and distribution of interstitial cells of medullary substance (ICMS) in different parts of the rat renal papilla. The amount of lipid granules containing precursors of prostaglandin synthesis in ICMS was counted. The maximum lipid granulation of ICMS was found in the papilla center. The electron-microscopic study has recognized 3 types of ICMS: little differentiated (located in the papilla apex), highly differentiated (prevailing in the center) and cells of the transitional type. The degree of lipid granulation of ICMS showing the intensity of the prostaglandin synthesis and the character of distribution of ICMS seem to correlate with the functional heterogeneity of the medullary substance.
研究了大鼠肾乳头不同部位髓质间质细胞（ICMS）的结构和分布特点。对ICMS中含有前列腺素合成前体的脂质颗粒数量进行了计数。发现ICMS的最大脂质颗粒化出现在乳头中心。电子显微镜研究识别出3种类型的ICMS：低分化型（位于乳头顶端）、高分化型（在中心占主导）和过渡型细胞。显示前列腺素合成强度的ICMS脂质颗粒化程度以及ICMS的分布特征似乎与髓质的功能异质性相关。
