Cholestasis (disturbance of the liver bile outflow into the duodenum) is a frequent complication of cholelithiasis and other pathologies of the hepatobiliary system. In this case, all metabolism types are disturbances and all body organs and systems, including the nervous system, are affected. The objective of the study was to establish changes in the c-fos immunoreactivity in the cerebellum neurons of rats at different time after modeling subhepatic cholestasis. In this work, we used a material of 60 white male rats 200–250 g in weight. In experimental animals, the ligation of the common bile duct was carried out, in control animals – a false operation while maintaining a physiological bile flow in the duodenum throughout the experiment. Subhepatic cholestasis in rats is accompanied by an increase in the cortex cerebellum on the 2–20th days after the ligation of the common bile duct of the number of neurons with the increased c-fos-immunoreactivity, with the maximum one on the 10th day of the experiment. In surviving animals, after the removal of cholestasis in the long term (45–90 days), the number of neurons with the increased c-fos immunoreactivity, as well as the expression of this protein in neurons is normalized.
