[Long-term results of chronic occlusion recanalization in patients with coronary heart disease].

The study was undertaken to assess the long-term results of recanalization of chronically occluded coronary arteries, by applying drug-eluting stents to patients with coronary heart disease. The study enrolled 585 patients with one-vessel occlusive lesion of one of three great coronary arteries (TIMI 0; occlusion duration, > or = 3 months): 321 patients who underwent successful recanalization of chronic occlusion and further implantation of drug-eluting stents and 264 patients who received drug therapy (a control group). The short- and long-term results of recanalization were investigated.

[Risk-group patients due to the administration of iodine and gadolinium preparations for diagnostic clinical study].

The paper discusses the concept of risk-group patients who have an increased probability of immediate systemic adverse reactions to contrast agents used clinically in various radiodiagnostic techniques. It analyzes the pathogenesis of allergoid reactions to X-ray and magnetic resonance, contrast media. On this basis, the authors describe the abnormalities and nosological entities the patients had in their medical history before diagnostic studies will be indicative of the increased risk of these complications to the administration of a contrast agent.

[Effects of anion channel blockers NPPB and DIDS on tobacco pollen tube growth and its mitochondria state].

Influence of anion channel blockers NPPB and DIDS on pollen tube growth and its mitochondria functioning was studied by means of fluorescence microscopy and flow cytometry. NPPB (40 microM) blocked pollen tube growth completely, but did not change its diameter. DIDS (20-80 microM) caused pollen tube swelling and bursting, suggesting that DIDS-sensitive channels take part in the regulation of pollen tube osmotic balance.

[Methodology of studying health based on population register].

Morbidity among the Moscow population receiving medical care at clinical hospital No. 85 and among workers, particularly those occupationally exposed to harmful factors, has been studied using an original system of automated processing of medical statistical information. The structure and incidence of the major groups of diseases has been studied in comparison with the mean data for Moscow.
