Glandular stomach hemorrhage induced by high dose saccharin in young rodents.
In studies primarily designed to evaluate the effects of saccharin and silicate on the urinary bladders of rodents, hemorrhage of the glandular stomach was observed in high incidence. It occurred in young rats with high doses of saccharin (7.5% sodium saccharin; 6.3% acid saccharin), with no difference between male and female F344 rats fed during ages 5 to 15 weeks. no difference between sodium saccharin and acid saccharin, and was reversible, even with continued saccharin administration. Sodium silicate (0.38, 1.13, 2.26% of the diet) had no influence on gastric hemorrhage. Iron deficiency anemia has been observed in young rats fed high dietary levels of saccharin, and the present results suggest that gastric hemorrhage contributes to its etiology.
