Effect of liraglutide on microcirculation in rat model with absolute insulin deficiency.

Introduction: The investigations of angiotropic effects of liraglutide are an issue of significant scientific and practical interest. The successful application of liraglutide has been shown in glycemic control in patients with the type 2 diabetes mellitus (DM), but the effect of liraglutide in patients with type 1 DM has not been completely studied yet in clinical practice. Therefore, the present study is aimed to investigate the effect of liraglutide which is agonist of glucagon-like peptide-1 receptors, on microcirculation in white outbred rats with the alloxan-induced diabetes.

Influence of the new formulation based on silver alginate microcapsules loaded with tannic acid on the microcirculation of the experimental periodontitis in rats.

The microvascular changes caused by disorders of host immune response to oral microorganisms resulting in long-lasting inflammation of gums play a critical role in the periodontal lesion in the pathogenesis of chronic periodontitis. Current strategies of non-surgical periodontal therapy are aimed at the attainment of anti-inflammatory effects. We hypothesized that the usage of the microencapsulated form of anti-inflammatory substances with vasoactive effects could enhance the efficiency of the therapy by the prolonged release of active components.

TNF-alpha and gamma-irradiation induced activation of the Salmonella typhimurium reproduction in the organs of infected animals.

The goal of the current work is to determine the role of the TNF-alpha on the activation of the bacterial growth in an in vivo system. In order to reach this goal we studied the dynamics of the reproduction of vegetative forms of Salmonella and the recultivation of non-cultivating forms of Salmonella in infected animals. Experiments have been conducted both on animals that had been injected with exogenous TNF together with bacterial suspension and on animals that had been exposed to gamma-radiation before infection, since it is known that irradiation increases the secretion of TNF.
