Plural growth factors in the supernatant of embryos and adult muscles of chickens

An attempt was made to isolate the cell proliferation stimulation factors in the supernatant of embryo carcases and adult muscles of chickens. Evidence was obtained for the presence of at least two or more stimulating factors in both the embryonic and adult muscular supernatants. These factors did not require a supplement of sera or other supporting agents. Furthermore, the use of the salting-out method with ammonium sulfate revealed two or more growth stimulants in the supernatant of chick cells.</p

A Case of Cold Urticaria associated with Cryofibrinogenemia

A case of cold urticaria in a 38-year-old woman was reported. The urticaria was demonstrated to have the following features: (i) The urticaria was associated with cryofibrinogenemia (ii) The passive transfer test was negative both with the patient\u27s serum and with cryofibrinogen. (iii) Whereas orally administered Tavegyl was not effective, Periactin proved to be effective in the treatment of the condition

Preparation of UO_2 Fine Particle by Hydrolysis of Uranium(IV) Alkoxide

Fine particles of uranium(IV) dioxides were obtained by hydrolysis of uranium(IV) ethoxide which was synthesized by reacting uranium tetrachloride with sodium ethoxide. The monodispersed submicrometer particles were confirmed by SEM observation
