title: Histological examination of the liver after experimental administration of MK-801 and dexamethasone.
abstract: The aim of the research was histological assessment of the influence of MK-801 (NMDA receptor antagonist) and dexamethasone on the liver. The experiment was carried out on adult Albino-Swiss mouse males. MK-801 was administered in the dose of 0.3 mg/kg/24 h for 8 days, dexamethasone--in the toxic dose of 120 mg/kg/24 h. Liver slices stained with hematoxylin and eosin were examined with light microscope. The performed experiments revealed that MK-801 can cause morphological changes of the liver in the shape of increased transparence of hepatocyte cytoplasm and narrowing of the liver sinusoids. MK-801 intensifies liver damage induced by toxic doses of dexamethasone leading to focal necrosis of hepatocytes.
