[The correction of the immunohormonal disorders in patients with hyperplastic processes in the endometrium]. / Korrektsiia immunogormonal'nykh narushenii u bol'nykh s giperplasticheskimi protsessami v éndometrii.

Effects were studied of extremely high-frequency electromagnetic radiation (EHF ER) on indices for the immune and endocrine systems in 48 patients with hyperplastic processes in the endometrium. It is ascertain that along with the established normalization of parameters characterizing the above systems there occurs a return of correlations back to normal, which fact permits using EHF ER as an immunocorrective factor.

[The potentials of local and intravascular laser irradiation for eliminating the immunological disorders in patients with chronic pyelonephritis]. / Vozmozhnosti mestnogo i vnutrisosudistogo lazernogo oblucheniia dlia ustraneniia immunologicheskikh narushenii u bol'nykh khronicheskim pielonefritom.

61 patients suffering from chronic pyelonephritis in the stage of active inflammation associated with either urolithiasis (67.4%) or prostatic adenoma (32.6%) were divided into three groups. Group 1 received conventional antibacterial treatment, group 2 conventional treatment + local laser radiation (LLR), group 3 received combined therapy including intravascular laser irradiation of blood (IVLIB). The treatments efficacy was controlled by urine seeding for microflora and its sensitivity to antibiotics, by immunological supervision. The patients were found to have immunological abnormalities in the form of cellular and humoral immunity suppression, neutrophil phagocytic hypoactivity, elevated levels of medium-molecular peptides nonresponsive to standard antibacterial therapy. Adjuvant use of LLR improved humoral immunity and reduced total urine bacterial count. LLR replacement for IVLIB resulted in a complete regression of immunological shifts and more pronounced reduction of urinary bacterial contamination.

Possible application of the laser in immunobiology.

The human immune system acts a defence mechanism against exogenous or indigenous potentially harmful bodies, such as bacteria and viruses. The major histocompatibility complex (MHC class I and class II antigens) form key elements of legitimate body components, and the organization of MHC molecules allows T-lymphocytes to distinguish between legitimate and foreign bodies. On detection of a foreign component, T-cells activate the necessary pathways for destruction of the foreign body. Occasionally however the system breaks down and the result is a disease of an autoimmune nature. Both visible light and infrared low reactive-level laser therapy (LLLT) has been shown to act on immune system cells in a number of ways, activating the irradiated cells to a higher level of activity. Infrared LLLT has been shown to increase both the phagocytic and chemotactic activity of human leukocytes in vitro, for example. This is an example of photobiological activation. Photobiological cell-specific destruction is also possible using doses of low incident laser energy on cells which have been photosensitized for the specific wavelength of the laser, such as in photodynamic therapy (PDT) for superficial cancers. LLLT has also been shown to act directly and selectively on the autoimmune system, restoring immunocompetence to immunocompetence cells. Although much more research needs to be done, there are enough experimental and clinical data to show that the laser, and LLLT in particular, has a possibly exciting role both in immunobiological therapy for diseases of the immune system, and to activate and boost the normal reaction of the immune system components against harmful foreign bodies.
