[Renal potassium excretion in rats exposed to different carbohydrate metabolism treatments].
After administration of 5 ml/100 g of 1.25% KCl solution into the rat stomach, the excretion of potassium in urine was 529.7 +/- 19.4 mueq/100 g.4 hours. After the same amount of potassium in 1--10% solutions, 2% solution of fructose, or 2% solution of mannitol, the potassium excretion reduced by over 25%. Glucose exerted no effect on the sodium excretion. Injection of 0.4 unit of insulin per 100 g of body weight along with administration of standard amount of potassium led to a decrease in the potassium excretion to 358.8 +/- 16.8 mueq/100 g.4 hours. The data obtained suggest a close relation between the carbohydrate metabolism and the potassium transport in the kidneys.
