Ambient temperature and survival on a protein-deficient diet

Exposure to cold has been found to prevent liver necrosis in rats fed on a proteinpoor, sucrose-rich diet deficient in vitamin E (Naftalin, 195 I ) , to inhibit accumulation of fat in the liver in choline deficiency (Sellers & You, 1949,1952; Treadwell, Flick & Vahouny, 1957), and to accelerate liver regeneration after removal of the left and median lobes (Moss & Weiss, 1955).In the study of Treadwell et al. (1957) growth rate and efficiency of protein utilization of rats fed on a diet with 5 or 10 % protein were found to be better in the cold ( I " ) than at 25', the reverse obtaining with diets
