[Changing parameters of microcirculation, coagulogram and morphometry of the nucleolar organizers zone in the epidermis of patients with psoriasis].

Findings of morphology, coagulogram and microcirculation in the derma, i.e. pathogenetically significant parameters in the onset and progression of prosiasis, were analyzed for 100 patients with psoriasis. Essential changes were detected, which apparently bring about lesions in the histophysiology of tissue homeostasis.

[Study of proliferative activity and nucleolar organizers in the epidermis of patients with psoriasis]. / Issledovanie proliferativnoi aktivnosti i iadryshkovykh organizatorov v épidermise u bol'nykh psoriazom.

Time course of proliferative activity of the epidermis was studied in patients with psoriasis by analysis of histoautoradiography data and evaluation of the activity of the ribosome nucleolar organizers. The findings indicate that the proliferative activity is increased in psoriasis. The activity of the ribosome nucleolar organizers increases during the progressive stage of psoriasis and notably decreases during the stationary stage, while during regressive stage this activity is the same as in apparently normal (after resolution of eruptions) skin of psoriasis patients. The results indicate that evaluation of the activity of nucleolar organizers in psoriatic elements can serve as an important additional test in laboratory diagnosis of psoriasis stages.
