[Organization of monitoring of electromagnetic radiation in the urban environment].

The authors describe new current approaches to monitoring the environment, including the sources of electromagnetic radiation and noise. Electronic maps of the area under study are shown to be made, by constructing the isolines or distributing the actual levels of controlled factors. These current approaches to electromagnetic and acoustic monitoring make it possible to automate a process of measurements, to analyze the established situation, and to simplify the risk controlling methodology.

[A system of liver microsomal oxidation in hypoxia and hyperoxia].

Content and catalytic activity of cytochrome P-450 were studied using amidopyrine as a substrate of the I type and aniline as a substrate of the II type. In hypoxia content of cytochrome P-450 and metabolism of amidopyrine were increased, while the enzyme content and the substrate metabolism were decreased in hyperoxia.
