[The efficacy of membrane-stabilizing therapy in patients with chronic obstructive bronchitis].

A membrane stabilizing effect of endobronchial laser therapy and antioxidative drugs piracetam and solcoseril was studied in 83 patients with chronic bronchitis. Malonic dialdehyde was measured to evaluate effects of this treatment on cellular and humoral immunity, blood coagulation and lipid peroxidation. It was found that the addition of membrane stabilizers to standard therapy of chronic bronchitis lowered malonic dialdehyde concentrations while the addition of the stabilizers and endobronchial laser therapy relieved clinical symptoms earlier, improved parameters of immunity, hemostasis and lipid peroxidation.
