Abstract:
Thirty-six aborted embryos ranging from 64 days to 8 months were collected and epiphysial cartilage of the finger and long bones of limbs were studied histologically. The results are as follows: 1.Degeneration of cartilage cells of different degrees were seen in the cartilaginous tissues examined. 2.Some of the cartilage cells necrosis were alone and others formed a mass of 3 to 5 or from 5 to 10 cells. 3.The elder the age of embryo was, the higher the rate of cell necrosis would be. 4.There were noncellular regions and giant cells in the normal cartilaginous tissue. The authors consider these changes are rather physiological in nature and would be a necessary process in the development of the cartilage.
