[Low-intensity laser radiation in therapy of bronchial asthma].

Efficacy of low-intensity laser radiation (LR) was studied by changes in a histamine level in peripheral blood and external respiration function (ERF). A total of 228 patients with exogenic bronchial asthma (EBA) were divided into two groups: 167 patients with nonhormone dependent asthma (group 1) and 61 patients with hormone-dependent bronchial asthma (group 2). Low-intensity LR lowered a histamine level and improved ERF in both group 1 and 2. A definite negative correlation was found between histamine content and ERF parameters. Laser therapy alone is effective in mild EBA. For moderate and severe EBA and hormone-dependent bronchial asthma a combination of conventional drug therapy with low-intensity LR is recommended.
