Influence of Combined Laser and EHF-Irradiation on Correction of Microcirculator Disorders in Inflammatory Diseases of Parodont

Aim - to prove the necessity of including the methods, which normalize the vascular and intravascular component of the hemostasis system, in the combined therapy of inflammatory periodontal diseases, as the microcirculation disorders play the most important role in the pathogenesis of inflammatory periodontal diseases and correlates with severity level. Materials and methods. In order to study the possibility to correct the malformation of the adhesive and aggregation activity of the blood platelets in patients with inflammatory periodontal diseases, we carried out a study of the adhesion and aggregation of platelets after a course of combined therapy, which included combined effects of laser and EHF radiation. The most important link in restoration of microcirculation is the vasoregulative effect of laser irradiation. Results. There is a partial or complete restoration of aggregation and adhesive activity of the blood platelets. Conclusion. The use of combined laser and EHF radiation of the “Matrix” equipment allows stopping the inflammation of the tissues quickly. Correction of these disorders by non-drug methods, in comparison with a medication-assisted treatment, has no side effects, and can be recommended as a component of combined therapy in patients with inflammatory periodontal diseases.

Effect of acoustic pulses and EHF radiation on multipotent marrow stromal cells in tissue engineering constructs

In this paper, we studied the effects of physical factors, such as, acoustic pulses of laser-induced hydrodynamics (ALIH) and extremely-high frequencies (EHF) radiation, on the formation of heterotopic bone marrow organs. A suspension of precipitated bone marrow cells from CBA mice were exposed to ALIH pulses and EHF radiation separately and in their combination tissue engineering constructs, presenting gelatin sponges 2 by 2 by 2[Formula: see text]mm in size containing 107 nucleated bone marrow cells, were exposed to physical factors and were implanted under the renal capsules of syngeneic mice. The newly formed hematopoietic organs were examined in three and five months later after treatment. The five months old transplants were bigger in size than the three months old transplants. The number of hematopoietic cells in the rest of the groups increased during this period by a factor from 3 to 10, the increase being as high as 20-fold in the ALIH[Formula: see text]EHF group. Maximal concentration of multipotent stromal cells (MSCs) was in the EHF[Formula: see text]ALIH, and minimal concentration was in the ALIH[Formula: see text]EHF. The accumulation rate of bone capsule weight was highest for the transplants of EHF[Formula: see text]ALIH and ALIH-sponge groups during the first three months. These data showed that the combined impact of the EHF[Formula: see text]ALIH on MSCs is the most effective for the formation of bone marrow transplantation.

This article describes a study of spontaneous and induced EHF-radiation temperature fluctuations in water solutions of glucose. There is shown a linear dependence of the relative magnitudes of repetition periods of the autocorrelation function and the relative frequencies of the Fourier transformation coefficients of the glucose concentration.
