[Angioprotective activity of mexicor in atherosclerosis obliterans of the lower limbs].

The authors have studied mexicor's efficacy in a comprehensive treatment of 25 patients suffering from atherosclerosis obliterans of the lower extremities with grade II-III ischaemia. The state of the vascular bed and the degree of arteries' narrowing were assessed by means of colour duplex scanning of the lower limb arteries using the unit Vivid 7 manufactured by the Company <>. The angiographic examination of the vessels of the lower extremities was carriedout on the angiographic complex manufactured by the Company Siemens Multistar T.O.P. The volume of the filling of the vessels of the lower limbs was evaluated by the parameters of the rheogram registered on the rheograph 4RG-1A. It was determined that the inclusion of mexicor (5-6% ml intravenously dropwise, 300 mg/day) into the standard therapeutic regimen significantly increased the efficacy of the conventional management of atherosclerosis obliterans of the arteries of the lower limbs, accelerating regression of the main clinical symptoms of ischaemia, increasing the distance of pain-free walking, correcting dyslipidaemia, and excreting an antioxidant action.

[Comparative pharmacokinetics of erythromycin target cell-associated transport and intravenous administration in patients with pneumonia].

The method of cell-associated antibiotic therapy consists of extracorporal exposure of the autoblood formed elements to antibiotic solution followed by their reinfusion. Pharmacokinetics of erythromycin after its intravenous and cell-associated administration in patients with community-acquired pneumonia and the clinical efficacy of the method were evaluated. HPLC of the erythromycin pharmacokinetic pattern in 20 patients showed that after the antibiotic target transport the pharmacokinetic model changed from one-compartment to two-compartment one and the antibiotic maximum concentration and elimination rate were lower vs. the intravenous administration. It was also shown that the clinical efficacies of the erythromycin intravenous administration and target transport did not significantly differ, whereas after the cell-associated transport of the antibiotic the therapeutic effect was observed earlier and the side effects were less frequent.

[The catalase activity and lipid peroxidation of donor blood under ultraviolet irradiation]. / Katalaznaia aktivnost' i perekisnoe okislenie lipidov donorskoi krovi pri ul'trafioletovom obluchenii.

Under study were catalase activity and indicators of lipid peroxidation (LP) of donor blood exposed to different doses of UV irradiation. Doses lower than 630 J/m2 were found to activate catalase and to inhibit LP while doses higher than 630 J/m2 inhibited catalase activity and activated LP. The indicators of LP have confirmed that therapeutic doses of UV-irradiated blood were nontoxic. The most optimal therapeutic dose of irradiation (630 J/m2) was determined.

[Ultraviolet irradiation of blood in surgery]. / Ultrafioletovoe obluchenie krovi v khirurgii.

The results of complex treatment of 81 patients with pyoinflammatory diseases with the use of blood ultraviolet irradiation are discussed. A marked clinical effect was noted, the terms of treatment reduced by 5-10 days, the outcomes improved, and the number of complications decreased. Irradiation of autologous blood by ultraviolet rays led to modulation of the indices of antimicrobial protection, increase of the intensity of the histochemical reaction to peroxidase up to 40-50%, and diminution of pH in the neutrophil phagosomes to 5.0. The ultrastructure and ability of thrombocytes to store serotonin were restored, and intensity of their metabolic processes increased, the membrane phospholipid composition changed, and juvenile platelet forms appeared.
