Abstract
Total osmotic pressure does not differ significantly in suction blister fluid or in serum of healthy persons from blister fluid, suction blister fluid or serum of patients with dermatitis herpetiformis, bullous contact dermatitis and pemphigus vulgaris. The average values reach about 293 mOsmol/kg. This results from direct measurement of total osmolality with an electronic semimicroosmometer based on the principle of freezing point reduction. In opposite to colloid osmotic pressure the total osmotic pressure does not take part in blister formation of human skin in spite of the different concentrations of the single electrolytes in the fluids of various blisters.
