NUTRITIONAL CYTOPENIA IN MONKEYS RECEIVING THE GOLDBERGER DIET.

Experiments are reported upon young rhesus monkeys which were given a diet essentially the same as the Goldberger black tongue-producing diet, supplemented in various ways. Those receiving the unsupplemented diet developed the syndrome characterized by leucopenia, anemia, gingivitis, diarrhea, and death, which has been previously described in monkeys receiving our diet of refined foodstuffs. An animal receiving the Goldberger diet supplemented with ascorbic acid and liver extract exhibited normal growth and development and has maintained a normal blood picture for approximately 2 years.

NUTRITIONAL CYTOPENIA (VITAMIN M DEFICIENCY) IN THE MONKEY.

Young rhesus monkeys (Macaca mulatta) were given a diet containing casein, polished rice, whole wheat, salt mixture, sodium chloride, cod liver oil, and ascorbic acid. They developed a syndrome characterized by anemia, leukopenia, and loss of weight. Ulceration of the gums and diarrhea were common, and death occurred between the 26th and 100th day.
