Survival of mice treated with 5% dextran sodium sulfate (DSS) on control and deficient diets. Mice were given a control (n = 15) or vitamin B₆-B₁₂-deficient (n = 16) diet for 2 wk followed by 4 days of 5% DSS administered in the drinking water. Survival was measured until day 6 when all remaining animals were euthanized. A significantly greater proportion of the deficient-diet animals (62.5%) survived until day 6 compared with those given the control diet (13.3%) (P < 0.05).
