[Changes in the morphofunctional status of the liver in rats with acute tetrachloromethane poisoning and their correction with antihypoxants, antioxidants and actoprotectors]. / Izmeneniia morfofunktsional'nogo sostoianiia pecheni krys pri ostroi intoksikatsii tetrakhlormetanom i ikh korrektsiia antigipoksantami, antioksidantami i aktoprotektorami.

The acute tetrachlormethane intoxication leads to structural and metabolic alterations in the rat liver. Morphological changes include centrolobular necroses and blood stasis in dilated sinusoidal capillaries. Metabolic changes are manifested by an increase in the water content and time of the spin-lattice (T1) and spin-spin (T2) relaxation (this indicates a lesser degree of water structuralization and its enhanced lability), and distortion of the correlation between T1 and T2. The prophylactic administration of one of the antihypoxants, antioxidants or actoprotectors normalizes the morphofunctional condition of the liver. According to the degree of the therapeutic efficacy, the examined preparations form the following series: dibunol > gamma-sodium hydroxybutyrate > tomerzol.
