[Evaluation of revascularization efficiency using near-infrared oximetry in patients with diabetic foot syndrome].

Objective: To evaluate prognostic significance of tissue oximetry in healing of trophic defects in patients with diabetic foot syndrome (DFS) after endovascular revascularization.

Material And Methods: In 42 patients with DFS, tissue oximetry was performed in angiosome projection with the FORE-SIGHT MC-2000 (CASMED) device before and the next day after revascularization of lower limb arteries. The 1st group included 30 patients with wound healing throughout 3 months, the 2nd group included 12 patients with amputation or no healing of trophic defects.

[Mönkeberg's sclerosis: role of calcification in arterial lesions in patients with diabetes mellitus].

The number of patients with diabetes mellitus has steadily been increasing. This disease is associated with the risk for the development of micro- and macroangiopathies. One of the variants of macroangiopathy is Mönkeberg's sclerosis characterized by the presence of calcification of the media of the arterial wall.

[Computer simulation of fibroblast effect on electrical activity in sinoatrial node cells].

Computer simulation of the electrical activity in sinoatrial node cells interacting via gap junctions with fibroblasts revealed that interaction with fibroblasts results in greater oscillation frequency of sinoatrial node cells. We have found out that fibroblasts also decrease the oscillation amplitude of the intrinsic central cells or completely suppress their spontaneous activity, while weakly affect the oscillation amplitude of peripheral cells.
