[Interrelations of macro- and microhemodynamics and lymph outflow in the cat liver during stimulation of the hepatic nerves].
Sympathetic electric stimulation of the liver nerves increased hydrostatic pressure in sinusoids by 8-10% in cats. The sinusoidal filtration coefficient decreased, particularly at the stimulation frequency 10-20 Hz. No significant increase in the lymph outflow from the liver was revealed which suggested an absence of the fluid transfer from the sinusoids to extravascular space. The above changes occurred against the background of the constriction of arterial, portal and venous vessels, as well as a reduction of the liver capacity. Comparison of these shifts with analogous values in small intestine revealed that the microcirculation in excitation of sympathetic-adrenal system is more stable in liver than in small intestine.
