title: [Acute gastric lesions induced by drinking water, in rats].
abstract: The ability of certain beverages and drinking waters to induce acute gastric lesions was studied and the measurement of their pH was performed. 1) Saline; 2) tap water; 3) well-water; 4) well water plus puritabs; 5) saline plus 2 Cl drips; 6) saline plus 4 Cl drops; 7) saline plus 8 Cl drops; 8) boiled water after 30 min; 9) apartment deposit water; 10) WC bowl water; 11) ice water; 12) Paraná river water (Northern Rosario); 13) Paraná river water (Southern Rosario); 14) rain water (Rosario); 15) rain water) countryside); 16) carbonated mineral water; 17) non-carbonated mineral water; 18) soda; 19) flavored electrolytic water I; 20) flavored electrolytic water II; and 21) cola drink. We can conclude that: 1) a remarkable variance in saline and tap water pH is observed. 2) Rain water and Paraná river water were slightly acid, in contrast electrolytic carbonated beverages and cola drink were strongly acid (pH 2.5). 3) Saline, pH 6.68; saline plus 2 Cl drops; and non-carbonated mineral water were the only beverages that did not induce acute gastric lesions in rats.
