[Evaluation of the level of cancerogenic waste in energetics and calculation of its effect on air pollution].

Investigations showed that heat plants pollute atmospheric air in towns of Khabarovsk district. Concentrations of benzo(a)pyrene in air of Khabarovsk, Komsomolsk-on-Amur, and Amursk are 4-14 times higher than its maximum allowable concentration.

[Ion conductance channels of bilayer from sarcoma-45 phospholipids].

Properties of black bilayer membranes formed from sarcoma-45 phospholipids differed from those of normal cell phospholipids bilayers. Two types of Ca2+-channels were discovered: those multiple to 35 pA and those multiple to 90 pA. The study of bilayers from phospholipids of nuclei, mitochondria, microsomal fractions showed that Ca2+-channels were localized in the microsomal fraction of transformed cells.

[Ultrasonic tomography in assessing the efficacy of the combined treatment of fibrosarcoma].

Ultrasonic tomography was used in 40 patients with locally-advanced fibrosarcoma of soft tissues who had undergone polychemotherapy or radiation in combination with short-term (5-10 minutes) ultrasound or microwave treatment of physical therapy intensity (1-2 W/cm2) given as a modifier. These procedures were used prior to surgery in 24 cases and as the only treatment--in 16. Ultrasonic tomography was performed before start, in the middle and right after termination of therapy, and before surgery.

[Functional state of body systems in local hyperthermia].

The bioelectrical activity of the cerebral cortex, cardiovascular system status, cell-mediated immunity and peripheral blood parameters were studied in 208 cases of head and neck cancer who received local pneumo- and ultra-high frequency hyperthermia in combination with chemoradiation treatment. Local hyperthermia was found to produce no untoward side-effects.
