The placenta obtained from women 6--10 weeks' pregnant were cultured in suspension, and consecutive phase microscope observations of the newly developed cells were compared with histochemical findings. The modes of development, which reached a maximum in 24--48 hr after start of the culture, were divided into: branched form, piled form, ard membranous form. The tissue cultured for 2 days was irradiated with 2000 and 4000 r and changes of the trophoblast were examined. The changes due to 2000 r of x irradiation became prominent in 2--3 hr after irradiation, and a gradual return to normal from the histechemical and phase- microscopic standpoint occurred in 12 hr. After 4000 r x irradiation, however, an irreversible change was shown, and degenerative and necrotic lesions became dominant. A reactive stimulating state induced by x irradiation was not noted by morphological observations. (Abstr. Japan Med., 1: No. 10, 1961)
