Abstract
The iso-electric point of cancer cell was examined according to Pischinger's method, in 37 cases of uterine cancer subjected to operation. Iso-electric point proved to he greatly affected not only by the maturity of the parenchyma, but also by the state of the stroma of tumor. As for the type of parenchyma, basal-cell carcinoma were studied. As lizima reported, bigger cells gave higher value of iso-electric point and the smaller the cell was the smaller the value of iso-electric point. In the anaplastically proliferated areas, the lowest value was observed. In the more fibrous area, higher value was checked. At the advancing margin of the tumor with exudative or granulomatous stromaI reactions, cells of low value of iso-electric point were seen. Therefore, it may be presumed that the growth of cancer is more or less affected by resistive reaction. As in the case of gastric cancer, our results will support Imai's idea that in order to understand histologically the development of cancer, a great emphasis should be given upon the analysis of the interrelationship between parenchyma and stroma of tumor.
