The comparison of lysosomal enzymes activities in alveolar and peritoneal macrophages of rat.
Studies were carried out on macrophages isolated from control and thioglycollate injected rats. Intraperitoneal injection of thioglycollate had no effect on the number of harvested alveolar macrophages but caused a marked increase in the number of peritoneal macrophages. The specific activities of all the investigated enzymes were significantly lower in peritoneal macrophages from control rats in comparison to alveolar macrophages. Thioglycollate stimulation of peritoneal macrophages caused increase in activities of all lysosomal hydrolases studied. Cathepsin B, N-acetylglucosaminidase and esterase showed the highest level of stimulation.
