Besides Purkinje Cells (PC) in cat cerebellum, experiments on Microwave-Living System interaction have been performed on some antioxidant enzymes — Super oxide dismutase (SOD), Catalase (C) and Glutathione peroxidase (GP) in the eye structures (pigment epithelium and neuronal structure — retina) in frogs, and on Glucose-6—Phosphatedehydrogenase (GPD) and Pyruvate-kinase (PK) in different organs — cerebellum, hypothalamus, liver and erythrocytes — of wistar albino rats. Exposure parameters of Microwaves of decimetre range (DRM) — total exposure, λ=65 cm, duration of exposition 10–20 minutes. According to the data obtained it may be concluded that, PC increasing their impulse activity irregularity, may react to the energetic (thermal) component of DRM action, whereas the result of informative (subtle) interaction between DRM and PC leads to the increase of regularity in electrophysiological activity of the latter. In the case of enzymes, in identification of the character of interactions, the type of the enzymes, the structure where an enzyme activity is studied and the physiological conditions related to such a factor as hunger, for example, take places. In this paper the effects of DRM on PC, G6PD and PK have been presented. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]
