title: Aryl hydrocarbon hydroxylase activity in cultured lymphocytes of psoriatic patients.
abstract: To evaluate further the metabolic capacity of psoriatics, the activities and inducibility of aryl hydrocarbon hydroxylase (AHH) were measured in cultured mitogen-stimulated lymphocytes from the peripheral blood of 68 psoriatic and 39 control patients. There was no significant difference in the mean basal and induced AHH activities between the psoriatics and the controls, although the former showed a slight tendency towards a higher inducibility ratio. In both, the basal and induced AHH values decreased significantly with increasing age. The cigarette smokers in both groups had significantly higher AHH activities than the nonsmokers. Antipsoriatic treatment (Anthralin, PUVA) did not seem to influence the lymphocyte AHH activities. No association was demonstrable between the AHH activities and the duration of the disease.
