[The nature of transepithelial potential of the liver].
The method of continuous monitoring of rat liver transepithelial electrical potential in situ (the potential between electrodes inserted into the common bile duct and blood flow) with simultaneous measurement of liver blood filling by photoelectroplethysmography is described. It was suggested that spontaneous oscillations of potential value with the period 20-30 sec found in the experiment were associated with synchronous oscillations of blood vessels and bile ducts cross section square caused by synchronization of pre- and postcapillary sphincters activity.
