[Prophylactic effect of vitamin A, neutralizing the development of experimental insulin-dependent diabetes in animals].

Vitamin A deficiency contributed to higher incidence of abnormalities in experimental animals with insulin-dependent diabetes induced by alloxan. However, the similar doses of alloxan did not cause diabetes in the animals maintained on a diet containing adequate amounts of vitamin A used for prophylactic purposes for a long time. The natural diabetogenic factor specific to insulin-dependent diabetes was not found in the blood serum of these animals.
