Positive Effect

In patients with chronic posttraumatic octeomyelitis of crus bones the influence of intravenous quantum photohemotherapy of ultraviolet diapason on microcirculation was studied. Efficacy of ultraviolet blood irradiation was assessed by laser Doppler flowmetry with optic tissue oxymetry canal. It was shown that treatment had positive effect on the main indices of microcirculftory bed, promoted activation of blood regulation in microvessels and certain increase of oxygen consumption by tissues. Increase of inflammatory activity was noted in no one out of 19 treated patients.

Walking in water (Aquatic Physiotherapy) is a simple, reproducible and affordable method. Warm pool water reduces peripheral vascular resistance. Purpose of the study was to assess the effect of dosed physical activity in a fresh water on the microcirculation of patients with arterial hypertension (AH) when applied externally. Materials and methods. The study included 14 subjects (7 men, 7 women) aged 18 to 70, with AH stage I. The patients were administered aqua training course in the form of walking in a fresh water for the 30 minutes duration, the course of treatment included 10 procedures, the water temperature in the pool was 30–32C. Before and after the end of the intervention, several parameters were monitored, including the assessment of microcirculation using laser Doppler flowmetry. Results: In patients receiving aqua training in a fresh water, there was a significant decrease of arterio-venular bypass grafting by 25.0%from the initial (Wilcoxon T-test = 310.0; p = 0.004) and an increase in the muscle component of microcirculation regulation (Wilcoxon T-test = 399.0; p <0.05), which indicates an improvement in microcirculation under the influence of aqua training. The optimal duration of training in fresh water was found to be equal to five days, after which the indicators characterizing microcirculation remain at the plateau level, without significantly changing. Significantly more often, the positive effect of aqua training was achieved in the group of patients with microcirculation disorders of the type of venous stasis (χ2 = 10.6; p <0.001). Conclusion. Laser Doppler flowmetry screening may be useful method to select patients with AH in a greatest need of aquatic training.

Background: Prostanoids are used in the treatment of Raynaud’s phenomenon and acral perfusion disorders secondary to collagenosis. In subjective terms, intravenous administration of these agents produces success in more than 50% of patients. The therapeutic outcome of clinical administration of alprostadil or iloprost may vary from individual to individual. Patients and methods: The following variables were analysed in a cross-over study in 27 patients with collagenosis and Raynaud’s phenomenon: plasma viscosity and erythrocyte aggregation (rheological variables), partial pressure of oxygen and laser Doppler flowmetry in the finger region, and lymphocyte phenotyping and interleukin (IL) determinations (immunological variables). Results: Laser Doppler flowmetry revealed significant differences between patients with secondary Raynaud’s phenomenon and a control group of 25 healthy subjects. Laser Doppler readings did not change significantly as a result of the treatments. Therapy with iloprost produced a reduction in IL-1beta, L-selectin (CD 62 L) and IL-6. Conclusion: The change in immunological variables due to iloprost may explain the long-term effects of prostaglandins in the treatment of Raynaud’s phenomenon. From our results it is not possible to infer any preference for iloprost or alprostadil.

Relevance. Morpho-functional changes in peripheral circulation established in type 1 diabetes mellitus correlate with changes in central hemodynamics, allowing the use of microcirculation indicators as diagnostic and prognostic criteria for assessing the degree of functional vascular disorders. Identifcation of microcirculation features of the blood by the method of laser Doppler flowmetry in children with different experience of type 1 diabetes in key age categories.Materials and methods. The study included 67 children with type 1 diabetes mellitus aged 12-15 years with an experience of the disease from six months to ten years. The comparison group consisted of 38 healthy children. The state of the microvasculature was assessed by laser Doppler flowmetry using a laser analyzer for capillary blood flow LAKK-OP.Results. In children with an experience of type 1 diabetes of less than two years, microcirculation disorders in periodontal tissues correspond to the hyperemic form, accompanied by increased perfusion, a decrease in the amplitude of low-frequency oscillations, increased heart rate, high blood flling, and blood flow bypass. For children with an endocrinopathy experience of more than three years, microcirculation disorders correspond to a stagnant form, combined with a decrease in perfusion due to stagnation of blood in the venular link, endothelial domination with suppression of neurogenic and cardiac fluctuations, low efciency and redistribution of blood flow in favor of the nutritive link.Conclusions. With the increase in experience, the degree of compensation of type 1 diabetes, the progression of diabetic microangiopathy, it is advisable to designate two stages of development of microcirculatory disorders. Early – compensatory with active adaptation, including neurogenic and endothelial regulation mechanisms. Late – decompensation with passive adaptation, supporting the effectiveness of microcirculation due to myogenic control of regulation, shunting and increasing the rate of blood outflow.
