Résumé :

Nucleate Amoeba fragments are less injured by U.V. irradiation than anucleate ones. Both nucleate and anucleate Amoeba fragments starved for ten days exhibit a greater U.V. sensitivity than amoebae starved only for one or three days. Photoreversal of the U.V. injury has been demonstrated in anucleate as well as in nucleate fragments. As demonstrated cytochemically, U.V. irradiation results in a decrease of nuclear and cytoplasmic basophilia in nucleate amoebae and of cytoplasmic basophilia in anucleate ones; the rate of glycogen utilization by nucleate and anucleate amoebae was decreased by U.V. irradiation. © 1957.
