Abstract
The role of subtypes of vasopressin receptors in modulation of renal sodium reabsorption was studied in in vivo experiments on Wistar rats. Selective V1a receptor agonist reduced sodium reabsorption in the kidneys and expression of these receptors increased by practically 100 times. This effect was similar to the effect of furosemide. Selective V2 receptor agonist enhanced sodium reabsorption in the kidney and simultaneously increased reabsorption of solute-free water. Stimulation of V1b receptors did not affect sodium transport. Our findings attest to the key role of V1a receptors in the regulation of renal excretion of sodium ions.
