CYCLO GFNFRATORI DEL EPITHELIO ORAL IN MUSES DE 400 DIES DE ETATE.-Cinquanta-quatro muses C57 de 400 dies de etate esseva subjicite al injection de thymidina a tritium, e autoradiogrammas esseva preparate ab le lingua, le palato, e le mucosa buccal. Le distribution del frequentia de marcate figuras mitotic esseva determinate a base de specimens obtenite a intervallos de duo horas durante 100 horas post le administration de thymidina a tritium. Le stadios del cyclo generatori esseva: synthese de acido deoxyribonucleic-8 horas, G 2—20 minutas, tempore mitotic—40 minutas, e interphase—approximativemente 80 horas.
