Peculiarities of functional neutrophil activity in rats having periodontitis in thesetting of toxic hepatitis

Abstract

Experimental toxic hepatitis was induced by single administration of Acetaminophen ( paracetamol) in a dose of 1000 mg per 1 kg of body mass in Wistar rats. Inflammation pathology was modeled by wounding the upper maxilla gingiva in toxic hepatitis rats on the 6-th day. Intact rats were controls. On the 1-st and 7-th day, ratio of neutrophil-macrophag was determined in smears of the upper maxillas gingival, oxygen-dependent functional activity of neutrophils was assessed based upon HST-test, functional activity reserves were assessed by the stimulation index. On the 7-th and 13-th day, alaninaminotransferase and aspartataminotransferase activity, level of general and indirect bilirubin, general blood protein were assessed in blood serum of these rats. Toxic hepatitis was established to be accomplished by increased biocidity of phagocytes, decreased functional reserves of neutrophils and their migration into the parodontium. In experimental inflammation, suppurative processes in parodontium tissues are revealed in toxic hepatitis rats by 1.5 times less than in controls due to lower biocide activity of phagocyte cells and increased migration of macrophages.
