A study of peritoneal macrophage activation has been conducted by simultaneous investigation in eleven enzymes in Balb/c Mice stimulated with bacterial extracts, by oral and parenteral route. The results showed important changes in Macrophage number and activity. On the other hand this activation depended upon the route of administration, antigen nature, and time interval between stimulation and peritoneal harvesting.
