Abstract
This study examined the phagocytic activity of rat peritoneal resident macrophages to determine the movement of macrophages in local inflammation in periodontal disease. We studied phagocytic activity by enzymelinked immunosorbent assay (ELISA) and used the peroxidase-anti-peroxidase soluble complex PAP; soluble immune complex) as a marker in.<BR>We also determined the basic conditions of this examination and studied the effects of bacterial components and the supernatants of sonicated periodontopathic bacterias.<BR>We obtained the number of applied macrophages, the concentration of PAP to use and the incubation time. The phagocytic activity of macrophages was enhanced significantly by the bacterial components lipopolysaccharide (LPS) and muramyldipeptide MDP).<BR>Phagocytic activity was also enhanced by the addition of the supernatant of sonicated Bacteroides gingivalis at 40μg/ml (concentration of protein) and significantly suppressed at 320μg/ml. Moreover, activity was significantly enhanced by the supernatant of sonicated Capnocytophaga suputigena at 40μg/ml and 160μg/ml, and suppressed by the supernatant of Fusobacterium nucleatum at a low concentration of protein (5μg/ml).<BR>These results suggested that LPS of gram-negative bacteria's endotoxicity and MDP on pivotal structure of peptidoglycans, which are bacterial cell surface components, exerted an effect on phagocytic activity. It was further indicated that the phagocytic activity of macrophages varied with the effects of each periodontopathic bacteria.
