Abstract

Six particulate preparations isolated from rat liver under different experimental conditions were analyzed biochemically and examined in the electron microscope. The results confirm the lysosomal nature of the pericanalicular dense bodies and demonstrate that the microbodies are the bearers of urate oxidase, catalase, and D-amino acid oxidase. Catalase, representing a major component of the particles, and D-amino acid oxidase appear to be associated with the structureless "sap" of the particles, urate oxidase with their crystalloid core or with their outer membrane.

摘要

对在不同实验条件下从大鼠肝脏中分离出的六种颗粒制剂进行了生化分析,并在电子显微镜下进行了检查。结果证实了胆小管周围致密小体的溶酶体性质,并表明微体是尿酸氧化酶、过氧化氢酶和D-氨基酸氧化酶的载体。过氧化氢酶作为颗粒的主要成分,与D-氨基酸氧化酶似乎与颗粒无结构的“液汁”相关,尿酸氧化酶则与它们的晶体核心或外膜相关。
