In situ coupling of chitosan onto polypropylene foils by an Atmospheric Pressure Air Glow Discharge with a liquid cathode.

Atmospheric air plasma treatment of chitosan solutions leads to degradation of chitosan molecules by OH radicals and is accompanied by a predominant cleavage of glycosidic linkages and by a decrease of the molecular weight. The degradation proceeds via first order kinetics with the rate constant of (5.73±0.

[The content of biogenic amines in the lymphocytes in bronchial asthma].

Serum serotonin and histamine were examined for their effects on lymphocytic dystrophic processes. During an exacerbation, there was an increase in the plasma concentration of biogenic amines (BGA) in patients with atopic and infective-and-allergic bronchial asthma. The elevated levels of BGA affected the activity of lymphocytes that were, on an exacerbation, in the functional stress accompanied by a derangement of adaptive processes that ended in cell dystrophy.
