[Mechanism of hypothalamic influences on bile formation].
Acute experiments were conducted on male rats; it was revealed that electrical stimulation of the nuclei of the anterior hypothalamus led to reduction of choleresis and to a fall of the potassium content in the bile, increase of permeability of the connective tissue stroma of the liver and of cell membranes of hepatocytes. Stimulation of the posterior hypothalamic nuclei induced an increase in choleresis, of the concentration of potassium ions and cholates in the liver, and also of the cholinesterase activity in the serum and homogenates of the liver. Permeability of connective tissue structures of the liver and of the intercellular spaces of hepatocytes proved to fall. The influences of the hypothalamus on bile formation included a change in the functional activity of hepatocytes and of the production of a fluid fraction of the bile.
