The linear interrelation between Systemic Arterial Blood Pressure and local Cerebral Blood Flow has been shown in experiments on rats with induced experimental hepatic encephalopathy. This is evidence of complete malfunctioning of the mechanism of Cerebral Blood Flow Autoregulation. Quantitative comparison of local Cerebral Blood Flow intensity in control and experimental (Hepatic Encephalopathy) animals has shown significant increase of the basic level of cerebral blood flow in rats with induced Hepatic Encephalopathy (p<0,05). On the basis of own and literature data the chain of developments in experimental hepatic encephalopathy was drawn: excess of Nitric Oxide because of hepatic failure can cause the cerebral vasodilatation with inadequate increase of cerebral blood flow intensity, resulting in malfunction of the cerebral blood flow autoregulation, increase of Blood Brain Barrier permeability, and penetration of toxic substances in nervous tissue. As a result of these--cognitive deficiency is developed (at the best) and hepatic coma (at the worst).

UI MeSH Term Description Entries
D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon

D006501 Hepatic Encephalopathy A syndrome characterized by central nervous system dysfunction in association with LIVER FAILURE, including portal-systemic shunts. Clinical features include lethargy and CONFUSION (frequently progressing to COMA); ASTERIXIS; NYSTAGMUS, PATHOLOGIC; brisk oculovestibular reflexes; decorticate and decerebrate posturing; MUSCLE SPASTICITY; and bilateral extensor plantar reflexes (see REFLEX, BABINSKI). ELECTROENCEPHALOGRAPHY may demonstrate triphasic waves.
