title: [The effect of salicylic acid on epidermal cell proliferation kinetics in psoriasis. Autoradiographic in vitro-investigations(author's transl)].
abstract: Salicylic acid in the therapeutic concentrations from 0.5 to 10% does not affect the rate of proliferation of psoriatic epidermal cells. In 18 patients suffering from psoriasis the H3-I (H3-thymidine labelling index) was determined using autoradiographic in vitro labelling techniques. In 12 of these patients double-labelling with C14-and H3-thymidine was used to determine the H3-I, the DNA-synthesis time (ts) and the duration of the cell-cycle (tc). No significant changes were observed following external application of salicyclic acid in white Vaseline in concentrations of 0.5, 2 and 10% for one week.
