Aim: The objective of the present study was to elucidate the character of microcirculatory disorders in the patients presenting with chronic viral hepatitis and to evaluate the possibilities for the correction of the associated disorders with the use of laser irradiation. Material and methods. All the patients were divided into three groups. Group 1 was comprised of 30 patients who were treated by means of traditional medicamental therapy alone; they served as controls. Group 2 consisted of 45 patients treated by intravenous laser irradiation in addition to traditional medicamental therapy. The patients of group 3 (n=45) received a course of laser skin treatment. The state of microcirculation was assessed by the laser Doppler flowmetry (LDF) technique with the help of a LAKK-02 apparatus (<
Results: The study has demonstrated heterogeneity of the types of microcirculation with the statistically significant increase in the frequency of its pathological cases. All the patients treated with the use of low-intensity laser therapy exhibited a significant improvement of the blood flow characteristics regardless of the initial hemodynamic type of microcirculation.
Conclusion: It is concluded that the application of laser irradiation as a component of the combined treatment of the patients presenting with chronic viral hepatitis facilitates correction of microcirculatory disorders.

During development, endothelial cells (ECs) undergo an extraordinary specialization by which generic capillary microcirculatory networks spanning from arteries to veins transform into patterned organotypic zonated blood vessels. These capillary ECs become specialized to support the cellular and metabolic demands of each specific organ, including supplying tissue-specific angiocrine factors that orchestrate organ development, maintenance of organ-specific functions and regeneration of injured adult organs. Here, we illustrate the mechanisms by which microenvironmental signals emanating from non-vascular niche cells induce generic ECs to acquire specific inter-organ and intra-organ functional attributes.

Background: This study aimed to analyze the metabolic risk factors for microcirculation disorders in patients with unstable angina (UA) after percutaneous coronary intervention (PCI), evaluating their predictive value for developing microcirculation disorders.
Methods: A single-center retrospective study design was used, which included 553 patients with UA who underwent PCI. The angiographic microcirculatory resistance (AMR) index was calculated based on coronary angiography data.

The autologous reconstruction of the female breast using a microsurgical DIEP flap is a reliable and safe method. To detect impairments early and preserve the microvascular flap through timely revision, a better understanding of physiologic perfusion dynamics is necessary. This exploratory study examines changes in microcirculation in free DIEP flaps within the first 72 h after vascular anastomosis using laser Doppler flowmetry and white-light spectrophotometry.

Acquired reactive perforating dermatosis (ARPD) is characterized by its onset after the age of 18 years, umbilicated papules or nodules with a central keratotic plug, and the presence of necrotic collagen tissue within an epithelial crater. ARPD is strongly associated with systemic diseases such as diabetes mellitus (DM) and chronic renal failure, which may contribute to ARPD through factors including microcirculatory disturbances and the deposition of metabolic byproducts, including advanced glycation end-products and calcium. Here, we report a case of ARPD that improved following DM treatment and catheter-based interventions for peripheral artery disease (PAD).

Aims: Coronary microvascular dysfunction (CMD) is a heterogeneous condition defined by reduced coronary flow reserve (CFR). The new index 'microvascular resistance reserve' (MRR) has been developed, but its role is unclear. We investigate the relationships between functional indices in ANOCA (angina and non-obstructive coronary arteries) patients and evaluate the hemodynamic features of different CMD subtypes.
