Introduction: Speleotherapy is the method of treatment in conditions of mines and karst caves microclimate. At 40-50-th this method have begun to develop in Germany, Austria and Italy. Later at the 60-th years speleotherapy was put in to practice in East Europe (Poland, Hungary, Slovakia, Romania). The high efficiency of this method of treatment at bronchial asthma (BA) patients is proved. However, there are technical reasons and medical contraindications, which do not give opportunities to some patients to be put down in underground department. Therefore, the apparatus, which enables to create an highdispersed aerosol of rock salt (haloaerosol) on the surface of the ground was worked out. The method of haloaerosoltherapy with the use of highdispersed aerosol of rock salt is successfully applied in Ukraine about 20 years. More than 10 years one regimen of treatment was applied in all patients. The course of treatment lasted 24 days and included 21-22 seanses of haloaerosoltherapy during 60minutes everyone. However, new economic conditions dictate necessity of improvement and reconsideration of some well-known methods of treatment on the basis of new data about bronchoobstruction mechanisms and new technical decisions. The way to increase the effectiveness of patients treatment in conditions of rock salt aerosol medium is the development of technologies, which allow to receive an aerosol of the given concentration and dispersion with the purpose of needed influence on various levels of the respiratory tract. The laser-optical system allowing to define a dispersion and concentration of rock salt aerosol was worked out. It has enabled to dosage an aerosol and to reduce the medical course. Aim: The main aim of our work was the approbation of different haloaerosoltherapy regimens in dependence of current diseases peculiarities and functional condition of the broncho-pulmonary system. The effectiveness of usual 24-day's treatment course, which included a daily 60-th minutes seanses of haloaeorosoltherapy (control group) with the reduced courses (research group) was compared. Materials and methods: There are 116 patients with mild and moderate persistent bronchial asthma (BA) were investigated. The patients were from 18 till 56 years old. The average period of illness was about 7,4 ± 2,5 years. All patients passed usual clinical, laboratory and functional examinations. The functional investigations of bronchopulmonary system included the definition of bronchoobstruction level and its primary mechanism on the basis of pharmacological tests. All patients were divided into 3 groups depending on ventilation's disturbances: patients with normal pulmonary functional tests (PFT); asthma patients with moderate disturbances of lungs ventilation; asthma patients with severe disturbances of PFT. All patients were treated according to 3 medical complexes (MC) (table 1):
