[Platelet activity in the chronic schizophrenic patients during attacks outcome and remission development]

The purpose of this work was to evaluate the degree of activation of platelets chronically schizophrenic patients with paroxysmal course of the disease during outcome from the attack of disease or in process of forming of the remission. Platelets in platelet-rich-plasma (PRP) and after PRP gel-filtration through the column with Sepharose CL-2B taken from the ulnar vein of males with chronic schizophrenia during outcome from the attack of disease or in process of forming of the remission were measured. Patients were investigated on the peak of the disease attack (visit 1), at the stage of significant improvement of clinical state (visit 2), and at the stage of stable drug-induced remission (visit 3). Platelet quantities in PRP prepared by centrifugation are equal in patients in visits 1, 2 or 3. These platelets quantities are much less than similar platelet quantities in healthy individuals matched in age. The additional decreases of platelet quantities were found after the elution of PRP platelets from the column with Sepharose CL-2B. These additional platelet quantity losses are increased from visit 1 to visit 3. Such losses of cells indicate decrease in their resistance to various influences, their activation in spite of remission development in this group of patients.
