Abstract
|
|
|
We made an attempt to investigate the plasmacytogenesis in the lymph nodes of rats shortly after the whole body X-irradiation. Albino rats were used, and their lymph nodes were examined 12, 36. 48 and 72 hours after whole body X-irradiation (400 R). The cells in a portion of area of proliferation of pyroninophilic cells observed by light microscopy, were observed by electron microscopy a series of transformed cells from the original cell to mature plasma cell.
The results were as follows:
In the area of proliferation of pyroninophilic cells by light microscopy in the lymph nodes, mature reticular cells, intermediated forms between reticular cell and transitional cell, transitional cells, proplasmacyte and mature plamacytes were observed in electron microscopic examination.
