SCANNING AND TRANSMISSION ELECTRON MICROSCOPIC OBSERVATION OF ENDOTHELIAL CELLS IN THE NORMAL CONDITION AND IN INITIAL STAGES OF ATHEROSCLEROSIS

Takio Shimamoto; Yoshiyuki Yamashita; Fujio Numano; Toshiaki Sunaga

The fine structures of vascular endothelial surface with linear endothelial folds, were clearly shown by scanning and transmission electron microscopes in large arteries and veins of man and other mammals and the nuclear parts of endothelial cells were shown in the gullies in scanning electron microscopical observation.

An autopsy case of malignant pheochromocytoma arising in the organ of Zuckerkandl is reported, of which distant metastases were found in the liver and lymph nodes. The biochemical and electron microscopic findings from the tumor tissue showed nor adrenaline‐ secreting type. It was revealed that sex ratio in malignant pheochromocytoma was more prominent in the female, and the frequency of extra‐adrenal origin was higher in malignant pheo chromocytoma than hi benign one from comparative study of reported cases of malignant pheochromocytoma.
