[Cells with phosphatase activity in the walls of subcutaneous capillaries from normal and inflamed rat tissue].

In the wall of rat's capillary blood vessels the adenosine triphosphatase is located on the endothelium, the 5'nucleotidase on the perithelial cells. The perithelial cells activities are strong during the inflammatory state, but at the beginning of the phenomenon the nucleotidasic cells become free into the oedematous tissue by preceding and accompagning the fibroblastic differenciation cells.
