Aryl hydrocarbon hydroxylase activity in cultured lymphocytes of psoriatic patients. 1982

N T Kärki, and J Karvonen, and O Pelkonen

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.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules.

D011565 Psoriasis A common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches. The lesions have a predilection for nails, scalp, genitalia, extensor surfaces, and the lumbosacral region. Accelerated epidermopoiesis is considered to be the fundamental pathologic feature in psoriasis.

D001189 Aryl Hydrocarbon Hydroxylases A large group of cytochrome P-450 (heme-thiolate) monooxygenases that complex with NAD(P)H-FLAVIN OXIDOREDUCTASE in numerous mixed-function oxidations of aromatic compounds. They catalyze hydroxylation of a broad spectrum of substrates and are important in the metabolism of steroids, drugs, and toxins such as PHENOBARBITAL, carcinogens, and insecticides.
