Observations were made on histological changes in the liver and spleen of the Vitamin B_6 deficient rats which were injected subcutaneously with 15 mg of L-cysteic acid per kg. of body weight on alternate days. Swelling of the spleen and enlargement of its follicles were recognized. These results suggest that vitamin B_6 prevents the injury of liver and spleen due to L-cysteic acid.
