HEMORRHAGIC SYNDROME IN RATS FED IRRADIATED BEEF. Progress Report No. 6, July 15, 1961-September 1, 1962

Technical Report ·
OSTI ID:4754613
Progress is reported in studies on the hemorrhagic syn" drome observed in rats fed irradiated beef. Various fractions of fresh and irradiated beef and other dietary components were assayed for their content of vitamin K. The chick assay method used for the determination of vitamin K is described. Data are included on the vitamin K content of lipid extract from fresh frozen beef. Amino acids were shown to alleviate vitamin K deficiency, the extracted protein from fresh beef was found to be more hemorrhagenic than that of irradiated beef, and the lipid extract from fresh frozen beef was found to have more vitamin K activity than that from irradiated beef. Squalene, vitamin A, and vitamin A acid were shown to produce effects in the chick similar to those in the rat. Results of preliminary studies in rats indicate that the mechanism of anticoagulant action of squalene may be in the bowel. (C.H.)
