The paper presents a brief review on how some concepts on the organism general adaptational reactions developed, including their role in increasing the unspecific resistance in the organism. Demonstrated is periodicity of the patterns of anti-stressor type reactions (training, calm and elevated activation) and stress in a wide range of stimulation values. The concepts on the organism adaptational reactions and reactivity levels have created the theoretical basis for practical applications of the activation therapy aimed at health improvement, prevention and treatment of various diseases, including oncology. Evidence data on the applications of the activation therapy as a promising approach to the organism state control are confirmed by the originators of this scientific discovery, their followers and medical experts.

AimThe aim of this paper is to discover some advantages and benefits of the complex treatment of patients with malignant gliomas of the brain with the use of electromagnetic field therapy. Materials and methodsOur examination focused on patients suffering from malignant gliomas of the brain. One cohort of them (the reference group covering 30 patients) received surgery and chemoradiotherapy (CHRT) without electromagnetic field exposure of the brain, while the other group (the main test group which included 30 individuals) was subjected to the same therapy, but accompa- IntroductionBrain tumors range from 2 to 8 % of all neoplasms in total. It is known that recent international reports represent a picture of a considerable growth of the inci dence rate of the brain tumors in populations through out the world. As to Russia, we can state the incidence rate of the brain tumors is 10 cases per 100 000 popula tion, with a half of the tumors located immediately in side the brain. By estimating the primary tumors of the brain in the adult population in Russia, statistics data show that gliomas of the brain accounts for 40-46 % of the cases, with 55 % of malignant tumors among them. Considering the glial tumors, the largest proportion is made by glioblastomas (16,7 %) as well as by astrocytic tumors (17,9 %), and in this case the malignant types of astrocytomas tend to occur 1,3 times more frequent
