[Peculiarities of metabolism of UV-irradiated lymphocytes].

The influence of UV-light (240-390 nm) at a dose of 151 and 755 J/m2 on the functional properties of lymphocyte metabolism key enzymes from donors' human blood: lactate dehydrogenase (LDH), cytochrome c oxidase, succinate dehydrogenase (SDH), Ca2(+)-ATPase of plasma membranes has been investigated. It has been revealed that photoinactivation of enzymes immediately after UV-irradiation which leads to the decrease of the ATP content in lymphocytes is replaced by the increased activity of the enzymes under investigation during daily incubation of lymphocytes. As a result, the level of ATP in photo-modified lymphocytes does not differ from that in native cells before incubation.

[Significance of multiple biopsies using the fiber bronchoscope in the morphological diagnosis of central cancer of the lung].

The paper discusses the first experience with fiber bronchoscope--mediated sampling for histologic examination in 183 cases of central carcinoma of the lung. As a result, cancer was histologically identified in 98.9% and cytologically verified in 60.
