Histochemical Distribution of Acid Phosphatase in Healing Wounds

F. A. Carranza Jr. 1 and R. L. Cabrini 1

1 Laboratorio de Anatomía Patológica, Hospital Ramos Mejía, Buenos Aires, Argentina

When wounds are inflicted in the palate, tongue and skin of Wistar rats and guinea pigs, acid phospatase activity in proliferating epithelium of these wounds is markedly decreased from that in normal epithelium; the enzyme reappears as soon as keratinization is evident. In connective tissue the enzyme is found especially in foreign body giant cells and in histiocytes in macrophagic function.
