[Morphology of the cells in the peritoneal exsudate and phosphatase activity of the peritoneal macrophages experimentally aged rats treated with the intracellular bacterium Brucella abortus 19 (author's transl)].
The authors study the morphology of the cells in the peritoneal exsudate and the phosphatase activity of the peritoneal macrophages, obtained from rats with Selye's Progeria-like syndrome. Judging by their morphologic characteristics the macrophages of the experimentally aged rats, before and after contact with Brucella abortus 19 do not differ from those obtained from the unsubjected to experimental ageing rats. The acid phosphatase activity and the adenosinetriphosphatase activity of the macrophages prior to contact with Brucella abortus 19 are nearly identical for both groups of animals. Following contact the activity of the enzymes increases but this increase is slower by aged rats and reaches its maximum 1--2 days later.
