title: [Effect of stimulation and depression of macrophages on development of paracetamol-induced acute toxic hepatitis in rats].
abstract: The role of macrophage (Kupffer cell) stimulation and suppression in the development of a toxic liver damage was studied in rats with acute hepatitis induced by paracetamol (acetaminophen, 1000 mg/kg). Pretreatment with carboxymethylated (1-->3)-beta-D-glucan (25 mg/kg, i.p., 48 h before paracetamol) for the macrophage stimulation or with gadolinium chloride (GdCl3, 7.5 mg/kg, i.v., 24 h before paracetamol) for the macrophage suppression has a protective effect manifested by normalization of the liver function test parameters and by a decrease in the degree of morphological changes in the liver cells. A relation between these positive effects and the TNF-alpha secretion by macrophages is discussed.
