Abstract
To investigate the effects of aluminum (Al) exposure on peritoneal macrophages of Wistar rats, four groups of ten rats each were orally exposed to 0, 13, 26, and 52mgkg(-1) Al(3+) in form of aluminum trichloride (AlCl(3)) in drinking water for 120days. At the end of the experimental period, the Al concentration in serum, the adherence, chemotaxis, and phagocytosis capacity of peritoneal macrophages were determined. The results showed that the Al concentration in serum significantly increased in a dose-dependent manner; the adherence, chemotaxis, and phagocytosis capacity of peritoneal macrophages decreased with the increase of Al dose, and present a dose-effective relationship. Further, they were significantly lower in the high-dose groups (P < 0.01) compared with the control group. It indicates that Al was toxic to peritoneal macrophages of rats, and the adherence, chemotaxis, and phagocytosis capacity of peritoneal macrophages in rats were significantly suppressed by exposure to 52mgkg(-1)day Al(3+).
