[The effect of interference currents on bronchial patency and bronchial hyperreactivity in children with bronchial asthma]. / Vliianie interferentsionnykh tokov na bronkhial'nuiu prokhodimost' i giperreaktivnost' bronkhov u detei, bol'nykh bronkhial'noi astmoi.

The results are available on introduction of interference therapy in 30 children with bronchial asthma versus control group of 20 untreated patients. Bronchoprovocative histamine and exercise tolerance tests have specified characteristic features of interference current effects on bronchial permeability and hyperreactivity.

[The effect of low-energy laser radiation in the infrared spectrum on bronchial patency in children with bronchial asthma]. / Vliianie nizkoénergeticheskogo lazernogo izlucheniia infrakrasnogo diapazona na sostoianie bronkhial'noi prokhodimosti u dete, bol'nykh bronkhial'noi astmoi.

Pulsed and continuous-wave low-energy infrared laser radiations were compared for effects on bronchial patency in 139 children with bronchial asthma aged 4-15 years. The pulsed regimen improved patency of the main bronchi in atopic asthma attacks and after them, while continuous-wave regimen improved patency of the peripheral bronchi in bacterial asthma in attack-free period.

[The adsorbed-DTP-m vaccination of children with allergically altered reactivity]. / AKDS-m vaktsinatsiia detei s allergicheski izmennoi reaktivnost'iu.

Immunization and booster immunization with adsorbed DPT-m vaccine was carried out, respectively, in 45 and 15 children with different severity of the course of an allergic disease, each child receiving simultaneously individually prescribed complex drug therapy. The postvaccinal period took a relatively favorable course. General and allergic reactions and complications observed after the injection of the preparation did not hinder the continuation of the course of immunization, while the appearance of neurological reactions provoked doubts on the expediency of the repeated injection of this preparation. A decrease in the content of diphtheria and tetanus toxoids in one immunization dose did not lead to the decreased synthesis of specific antibodies. The present investigation showed the possibility of using adsorbed DPT-m vaccine with reduced antigen content in cases of both the remission of an allergic disease and the subacute course of such disease.

[The functional diagnosis of bronchial hyperreactivity and bronchial lability in children with bronchial asthma]. / O funktsional'noi diagnostike bronkhial'noi giperreaktivnosti i bronkhial'noi labil'nosti u detei, bol'nykh bronkhial'noi astmoi.

During a remission, bronchial asthma children were examined for bronchial hyperreactivity and bronchial lability by means of graded physical exercise tests, and pharmacological tests with bronchoconstrictors and bronchodilators. It has been established that normal lung function seen during aa remission does not mean the lack of bronchial hyperreactivity whereas incomplete recovery of bronchial patency during bronchial asthma remission is always attended by bronchial hyperreactivity in almost all the cases. In carrying out functional tests for bronchial hyperreactivity and bronchial lability, the recording of the velocity parameters of forced expiration making it possible to define patency of not only the central but also of the peripheral bronchi appeared very informative.

[Obstructive bronchitis syndrome in acute viral respiratory diseases in young children]. / Bronkhoobstruktivnyi sindrom pri ORVI u detei rannego vozrasta.

External respiratory function was explored in 39 children aged 1.5 months to 2 years presenting with the bronchoobstructive syndrome (BOS) in the presence of acute respiratory virus infection. The development of the BOS was accompanied by disorders of bronchial patency and alveolar ventilation. The maintenance of adequate ventilation is reached at the expense of hurried breathing with the respiratory volume being lowered. During convalescence, bronchial patency rises, hyperinflation drops and the respiratory volume increases. Uniformity of the ventilation-perfusion relations in the lungs declines. The use of total body plethysmography and oxycapnography makes it possible to objectively estimate respiratory function and to control the efficacy of the treatment in infants.

[Evaluation of bronchial resistance in healthy children]. / Otsenka bronkhial'nogo soprotivleniia u zdorovykh detei.

Pneumotachography was used to examine bronchial resistance (BR) in 169 healthy children aged 6 to 16 years. A negative correlation was established between BR and the height, body weight and age. Regression equations were elaborated for computing due magnitudes of BR. The percentile distribution of BR makes it possible to refer children with BR from 130 to 140% of the due magnitude to the risk group and to consider the BR magnitudes exceeding 140% as pathological. The reproducibility of BR was determined. In view of this fact it is suggested that during pharmacological tests, the change of BR by more than 33% of the due magnitude should be regarded as significant.
