The adaptive response to acidosis was selected as one of useful criteria for judging nutritional adequacy to vital force. Acidosis was made by giving 1.5% NH₄Cl solution as a drinking water.
　Four-five weeks-old male Wistar rats were fed 15% casein diet, 5% casein diet, protein-free diet, mineral-deficient diet, vitamin-deficient diet and energy-deficient diet with 1.5% ammonium chloride solution for 9 days. Urinary ammonium ion excretion, renal glutaminase and phosphoenolpyruvate carboxykinase activities were determined. The ratio of urinary ammonium ion excretion to renal glutaminase activity was reduced in protein-, vitamin-, and mineral-deficiencies, but not affected in energy-deficiency.
