[Efficacy of treatment of lower-limb critical ischaemia by methods of indirect revascularization].

Aim: The study was aimed at comparing the efficacy of implantation of autologous bone marrow cells with that of revascularizing osteotrephination in treatment of lower limb chronic critical ischaemia in patients with a poor distal vascular bed.

Patients And Method: We analysed the results of comprehensive examination and treatment of a total of 60 patients presenting with lower limb chronic critical ischaemia due to atherosclerotic lesions of the femoropopliteal-tibial segment. According to the technology of treatment, the patients were divided into two statistically homogenous groups of 30 people each.

[Effect of actovegin and solcoseryl on microcirculation in experimental critical lower limb ischaemia].

The authors examined the effect of actovegin and solcoseryl on microcirculation parameters in treatment of experimental critical lower limb ischaemia. The study included a total of 130 male Wistar albino rats divided into four groups: intact, control, first and second study groups. The intact group consisted of 10 animals used for assessment of the normal indices of microcirculation, with the remaining three groups comprising 40 rats each.

[Experimental study of cardioprotective and endothelioprotective action of macrolides and azalides].

The cardioprotective and endothelioprotective effects of the macrolide antibiotics roxithromycin, azythromycin, and midecamycin have been studied on laboratory animals with models of the coronaro-occlusional myocardial infarction and endothelial dysfunction. The drugs led to a dose-dependent decrease in lethality, reduced the zone of necrosis of the left ventricle after coronary occlusion, and produced a positive effect on the functioning of endothelium.

[Pharmacological correction of experimental chronic limb ischemia].

In tests on a group of 250 rats, we studied (i) the level of microcirculation in the muscles of a healthy limb in the norm and (ii) the dynamics of microcirculation for 6 h after treatment with pentoxifylline in a dose of 60 mg/kg dose and L-arginine in a dose of 30 and 200 mg/kg. The chronic ischemia was modeled by excision of basic femoral artery. There was no significant difference in pentoxyfilline-treated animals in comparison to the control.

[Endothelioprotective properties of L-arginine in a nitric oxide deficiency model].

In laboratory animals with endothelial dysfunction (nitric oxide deficiency) modeled by the introduction of NO-synthase inhibitor L-NAME, the activation of endothelioprotective effects of enalapril, lozartan, amlodipine, indapamide and nebivolol is revealed for their introduction in combination with L-arginine. This result was confirmed by the behavior of a generalizing parameter, the coefficient of endothelial dysfunction (CED) calculated using the results of tests on endothelium-dependent and -independent vasodilation.
