Abstract

|
cis-Dichlorodiammineplatinum (II) (cis-Platin) inhibits the proliferation and growth of the tumor cells by way of inhibiting DNA and protein synthesis of the cancer cells. Although cis-Platin is very effective antitumor drug, it also produces many other side effects. Thus the author has studied the effects of cis-Platin on the proximal epiphyseal plate in the tibia of the rat. The results were as follows: In the chondrocyte of the proliferative zone, sacculated, and fragmented cisternae of rough endoplasmic reticulum, some mitochondria with disorganized mitochondrial cristae and distorted procollagens were observed, and in the matrix some large matrix granules and dispersed collagen fibrils were revealed on the 1st, 3rd day and 1st week group of cis-Platin treated rats. In the chondrocyte of the proliferative zone of cis-Platin treated rats on the 2nd and 3rd week group, parallely arranged rough endoplasmic reticulum and many procollagens were shown, and in the matrix a number of large matrix granules and many small matrical granules as well as collagen fibrils were revealed. Consequently it is suggested that though cis-Platin induces the degenerative changes of the chondrocyte resulting in components of the cartilagenous matrix, these toxic effects are regressed with time.
