Enterosorbents Polysorb MP and Polyfepan were tried in patients with chronic bronchitis in the stage of aggravation and with late gestosis. The trends in clinical and laboratory indices, in external respiration, cellular and humoral immunity, in the content of middle-weight molecules in relevant patients undergoing enterosorption with the above sorbents against the controls were more favourable. This supports validity of enterosorption in patients with chronic bronchitis and late gestosis.
