The studied of effects of vitamin C administration on the leukcocyte counts and testing of exercise of male rats.

Rats were divided into 4 groups ; the first group contain the control and the other group contain the administration with different doses of ascorbic acid (35mg, 75 mg, and 120 mg / day ; respectively.
