[Capacity and exchange functions of the kidney blood vessels at various leveles of venous outflow]. / Emkostnaia i obmennaia funktsii krovenosnykh sosudov pri raznykh urovniakh davleniia venoznogo ottoka.

In perfusion of the cat hemodynamically isolated kidney with a constant blood flow volume, responses of venous vessels to noradrenaline did not depend on the venous outflow pressure level and only involved a diminishing of the blood filling which distinguishes kidneys from other organs. The renal veins' capacity decreased in response to noradrenaline practically completely disappears in high values of the venous outflow pressure. The renal capillary filtration coefficient was shown to equal 0.21 +/- 0.11, whereas the effect of changes in renal vein's pressure on implementation of the microvessels' exchange function in determined by the shifts of capillary hydrostatic pressure.

The action of prostatilen on contractile activity of smooth muscles of isolated line slices of urine bladder of Wistar rats (myography) and arterial vessels of cat kidneys (resistography) was studied. On the basis of clinical cases effectiveness of prostatilen was analysed as a treatment restorting urine bladder function in acute reflex urinary retention after operations in the area of rectal sphincter, as well as in treatment of patients with chronic prostatitis. It is shown, that prostatilen produces contractile action on smooth muscles of renal blood vessels in cats and urine bladder walls in rats and it raises contractile activity of smooth muscles of human urine bladder. The results of experimental and clinical investigations make it possible to recommend the application of this bioregulating preparation for treatment and prophylaxis of disturbances in urination.

Prostatilene enhanced the functional activity of the bladder and blood vessels' smooth muscle cells. A possibility of activation of the smooth muscle cells contractility with prostatilene by a pharmaco-mechanical association, is discussed.
