[ROLE α2-ADRENERGIC RECEPTORS IN REGULATION PLATELET REACTIVITY IN THE ELDERLY AT CHRONIC OBSTRUCTIVE PYELONEPHRITIS].

Objective of the research was to determine involvement of platelets and the role of adrenaline in chronic inflammation maintaining and the initiation of acute inflammatory response in elderly patients with chronic obstructive pyelonephritis against this background. The study includes 60 patients with chronic obstructive pyelonephritis (COPN), which are distributed into two groups: basic - 22 elderly patients (age 73±1,5 years) and the comparison group - 38 middle-aged patients (52,5±2,4 years). The study excluded patients who took antiplatelet drugs and non-selective blockers of α adrenergic receptors at least 1 week before the study.
