[Seasonal fluctuations of the indicators of cellular and humoral immunity in persons with prenosological and nosological manifestations of chronic bronchitis].
A study was made of the tissue and humoral immunity in 276 persons with prenosological and nosological signs of chronic bronchitis among the indigenous population as well as in newcomers living under the conditions of ultracontinental climate. Seasonal fluctuations of indices of the cellular and humoral immunity were more noticeable in the former than in the latter. Persons with prenosological signs of bronchitis were characterized by less pronounced tension of the cellular immunity in autumn than healthy people whereas considerable inhibition of the cellular immunity and change in the rhythm of its seasonal fluctuations were noted in patients with chronic bronchitis.
