The effects of a protein-deficient diet, non-supplemented or supplemented with vitamin B6, on the white blood cell subpopulations in exercised and unexercised rats. The rats were fed the following diets for 90 days: a control diet (20% of energy from protein, groups I and II), low-protein diet (4.5% of energy from protein, groups III and IV), or low-protein diet (4.5% of energy from protein) additionally supplemented with 300% of vitamin B6 (groups V and VI). *– the level of divergence between groups (p < 0.05)
