Decreased citrate synthesis: possible indication of early degenerative changes in testes of vitamin E-deficient rats.

We have shown that intravenously administered glucose disappears from the blood of E-deficient rats at different rates compared to that of the control rats and that this difference could possibly be explained by membrane permeability changes in E-deficiency. We have also shown that the ability of E-deficient rat testis tissue to synthesize citrate is decreased, and that this decrease is probably an early manifestation of testicular degeneration.
