Abstract

1) The influence of acids and bases on the development of the early wound reactions in the intact and the mechanically injured skin of guinea pigs was investigated. The cellular and the enzymohistochemical reactions showed to be different: the tissue leucocytosis after mechanical trauma is less restrained by chemical effects than the reactive increase of enzymic activity in the border of wounds, which proved to be affected by acids more than by bases. Changes in activity of structure bound enzymes could not be demonstrated in the skin after mere action of acids and bases, but only after mechanical trauma. The cellular reaction is in the border of the base necrosis more compact, in case of the acid necrosis broader and more diffuse. Characteristic changes in the nucleus were preferentially found after basic reaction. 2) In the mechanically unhurt skin a significant excess of histamine was found after the action of acids, while the liberation of serotonin was distinctly decreased. After incision and addition of acid the histamine level was decreased and the serotonin concentration significantly increased. After exposition of guinea pig skin to chemicals, the concentrations of the so-called tissue hormones showed a contrary course. 3) After postmortal incision and following cauterization a distinct increase of histamine was found in the wound area. Generally the excess of free histamine in comparison to the unhurt skin is considered to be a vital reaction. But because degranulation of mast cells and liberation of histamine can also be caused by chemical influence in the postmortal period, a critical interpretation in cases of skin exposition to acids or bases is necessary.
