Cancer risks in the Kaluga oblast of the Russian Federation 10 years after the Chernobyl accident.

Cancer morbidity and mortality were studied in areas of the Kaluga oblast contaminated with radionuclides. The main objective of the study was to assess the influence of radiation exposure on existing levels of cancer morbidity and mortality. Time trends and relative population risks were analysed.

[Oncoepidemiologic situation in the Kaluga region of the Russian Federation ten years after the Chernobyl accident].

Cancer morbidity and mortality in radionuclide-contaminated areas of Kaluga Region have been investigated. The study was mainly concerned with the extent of radiation pollution influence on the present-day cancer morbidity and mortality rates. The correlations between the latter factors, on the one hand, and relevant population risks, on the other, have been analysed.

[Clinico-pathochemical substantiation of the exacerbation phenomenon in patients with ischemic heart disease during treatment with the helium-neon laser].

Some pathochemical mechanisms of coronary disease aggravation in the course of laser therapy were assessed by means of the measurement of erythrocyte membrane lipids and phospholipids as well as plasma alpha-tocopherol and diene conjugate levels. The aggravation was associated with an activation of metabolic processes aiming to produce regeneration of membrane structures. The regeneration takes place in the presence of chronic deficiency of total phospholipids and inadequate antioxidant protection of biomembranes, therefore complete stabilization and normalization of their composition and activity is impossible.

[Clinico-biochemical parallels against a background of traditional treatment and laser therapy of patients with ischemic heart disease].

The paper is devoted to analysis of clinico-biochemical indices and a quest for additional pathologico-chemical criteria at the cell membrane level of the efficacy of helium-neon laser therapy in coronary heart disease (CHD). Another task was to decipher a number of metabolic signs of the phenomenon of CHD "exacerbation" in laser therapy (during 4-6 sessions). Positive clinical results were obtained in 98% of the patients.
