Physical development and renal function in adolescents consuming drinking water with high content of vital cations
The article presents the data concerning the influence of drinking water with high content of vital cations on the physical development and renal function in adolescents of 10-12 years old. It has been found marked physical health and development decrease and changes in osmo- and ionuretic renal functions, reflected in the increasing of diuretic and ionuretic response in conditions of spontaneous urination, and after water loading. Evaluation of the sodium-potassium ratio in saliva demonstrated the rigidity of hormonal mechanisms of sodium-potassium homeostasis regulation following the consumption of hard drinking water, which was manifested in the absence of changes the parameter after the water load, whereas in the control group, this ratio decreased, reflecting the activation of corticosteroid mechanisms.
