[Chemicals as fire damaging factor].

The article provides an overview of published scientific data about toxic chemical compounds formed during thermal degradation of various materials. In case of fire the complex of physical and chemical factors affect the human, along with injuries, thermal burns of the skin and respiratory tract there is a lack of oxygen in the inspired air and the impact of thermal degradation products. The greatest number of deaths in.

[Cell-molecular mechanisms of nitrogen dioxide-induced damaging effect on bronchial epithelium].

Nitrogen dioxide and reactive nitrogen species play a key role in the development environment related diseases by initiation of cell death and damage of bronchoalveolar epithelium. This review examines the possible cell-molecular mechanisms of nitrogen dioxide-induced damaging effect on bronchial epithelium.

[Enterococci as a cause of infectious complications after surgery].

Self-obtained data about study of enterococci as etiologic agents of infectious complications after cardiovascular and transplantation surgery are presented in the article. 465 strains of enterococci were isolated from different biosubstrates. Isolation rate of different species of enterococci in blood, urine, fromwounds, trachea, cardiacvalves, as well as in the environment and on wear of healthcare workers were determined.

[Differential diagnosis of carcinogenesis stages in the uterine cervix according to the ploidometric studies].

Computer microscopy with nuclei ploidy visualization of tumour cells provides additional objective signs of malignant transformation of uterine cervix multilayer epithelium. Nuclear ploidometry is a differential diagnostic procedure which allows more precisely than routine methods to establish benign stages of neoplastic processes: intraepithelial neoplasia I (2.5-3.
