Vitamin E Deficiency in the Monkey . Iv .

NEMIA regularly develops in the rhesus monkey (Macaca mulatta) when it is deprived of vitamin E.1 The anemia is accompanied by granulocytosis,’ an increased concentration of bone marrow deoxyribonucleic acid,2 a reduction in the maximal Cr5’ survival time of the erythrocytes,3 a slightly elevated reticulocyte count1 and a prompt reticulocytosis following vitamin E administration. This combinati...

Vitamin E Deficiency in the Monkey

Eight young rhesus monkeys were fed a purified diet devoid of vitamin E. After from 6 to 13 months of feeding, all the animals developed signs of vitamin E deficiency. The signs of vitamin E deficiency in the monkey include muscular dystrophy, elevated excretion of creatine, allantoin, and free amino acids and decreased excretion of creatinine. The vitamin E-deficient monkeys all developed anem...
