- Thirty male rats were divided into 3 equal groups and fed regular pellets for 3 weeks. One group was ingesting tap water, another was given a solution of ammonium chloride (200 mmol/L in the drinking water), and the third group ingested a solution of sodium bicarbonate (200 mmol/L in the drinking water). aMean ± SEM, n = 10. bp <0.01 vs. water; cp < 0.05 vs. NH4Cl; dp < 0.001 vs. the other groups (ANOVA, with Tukey’s correction for multiple comparisons). Note that the food and fluid intake, for practical reasons, were recorded for 18 hours.
