Problem of cross-infection and infection in dental practice has become a matter of public concern. Changing public expectations for cross-infection control could improve safety precautions of dental care. Goal of the study was to determine the level of Knowledge, Attitude and Perception (KAP) of Georgian patients attending dental clinics regarding cross-infections and infection control measures in dentistry. A cross-sectional study was conducted among 570 participants from all 10 regions of Georgia and Tbilisi (the capital city) during 2019. A standardized, confidential, self-administered, close-ended questionnaire was used to assess respondents' knowledge, attitudes, self-reported practices, perception and behaviors toward cross-infection control measures in dental clinics. 71.4% (n 407) of participants were females and 28.6% (n 163) were males. 72.6%, 63.2%, and 62.5% of respondents agreed that they can catch during dental treatment HCV, HBV and AIDS/HIV respectively, while 50.5% and 55.8% mentioned about TB and respiratory infectious (RI) diseases respectively. 80% of participants are concerned about the risk to be infected during the dental treatment. 62.5% of participants responded that they would not receive treatment in dental clinic where HIV and HBV/HCV patients are being treated. Overall, the study suggests that participants' knowledge, attitude and perception regarding cross-infection control in dentistry need some improvements. This study will assist in planning more effective interventions to enhance public awareness about infection control in dentistry in Georgia.The article is interdisciplinary in nature and covers a wide range of issues in the history of medicine, morality and bioethics. Biographies of the Norwegian microbiologist G. Hansen and the German doctor, biologist, syphilologist A. Neisser are presented. The main attention is focused on the scientific achievements of these researchers in terms of infectious diseases and leprosy in particular. The authors focused not only on the significance of scientific discoveries, but also tried to show that any scientist, even an outstanding one, remains a person with his/her unique character, personal life and friendships, authority in the scientific community and mistakes, desire to gain fame and recognition. The main focus is on the scientific achievements of these researchers in the study of infectious diseases and leprosy in particular. The conflict over the priority for discovery of the leprosy pathogen has been highlighted. Attention is given to the conflict regarding the priority in discovery of the causative agrit of this high-profile scientific scandal, was simultaneously studied. It is shown that a series of A. Neisser's experimental studies on another threatening disease - syphilis, by inoculation also led to a scandal, ironically, similar to that one around the name of Hansen. However, neither his reputation, nor his medical license, or his further scientific career suffered a significant impact, although it has become a precedent for obtaining informed consent from persons taking part in clinical trials. The findings revealed that, despite the desire to serve science and humanity, compliance with the rules of bioethics, as well as human morality, should remain an integral component in the work of any medical scientist.Digital tomosynthesis (TS) are modern methods of low-dose x-ray diagnostics, which allows to obtain a significant number of layered images with the possibility of volumetric image reconstruction. The technology makes it possible to analyze a vast anatomical zone in one pass of the x-ray tube, to diagnose difficult-to-distinguish pathological changes that are not visible in digital radiography without losing the quality of the images, which is especially important in pediatric practice. The present literature data is devoted to the possibilities of using TS in the diagnosis of a wide range of diseases in children, as well as the prospects for further development of the methods to solve specific problems associated with the examination of children's patients.Aim - comparison of biological hermeticity, mechanical strength and differences in morphological characteristics of one-row and two-row colon anastomoses. 20 animals were used in the experiment. Rabbits of both sexes aged from 8 months to 1.5 years and weighing from 1.5 to 2.6 kg were used as experimental animals. The animals were divided into experimental and control groups. In the experimental group we used the developed technique of one-row colon anastomosis (CA) formation, in the control group - the traditional two-row CA. Assessment of mechanical strength was performed by using the original method of pneumopression of colon segment with the anastomosis. The biological hermeticity was assessed by culturing flushing water from the anastomosis line to growth medium. The morphological picture was evaluated by microscopy of histological samples from the anastomosis line. The mechanical strength of the one-row anastomosis, compared with the traditional two-row, was higher at each stage of the study, on the first day by 66.3%, the third - 87.6%, the fifth - 76.1%, the seventh - 85.4%. The formation of a one-row CA allowed to achieve biological hermeticity of the anastomosis area in all periods of the early postoperative period, and when using a double-row suture, the anastomosis area became sterile only from 5 day. Morphologically, the picture was characterized by inflammatory processes in the anastomosis area when using the original technique, which were stopped in 3-5 days, and in the control group they persisted for up to 7 days, accompanied by vascular paresis of the intestinal wall, blood stasis and blood clots, with zones of mucosal necrosis at 3 and 5 day of observation.The goal of this investigation was to study the effect of the electric-magnetic stimulation (EMS) on the activity of the HPA axis, which can change behavior activity. The experiments were conducted on mongrel, albino male rats, weighing 150- 200 g (n=14). Smad inhibitor Proceeding from the goals set, the experimental group (dexamethasone-treated-1mg/ per animal for 10 days) and the control group of rats were involved in the experiments. Each group was divided into subgroups. Some rats from the subgroup were given EMS. The Control group of rats received the same amount of saline. Electro-Magnetic stimulation parameters 10000 -15000 Hz frequency, 1,5 m/Tesla, for 15 min, during 10 consecutive days. The Forced Swimming, the Open Field, and the Active Wheel Tests were choosing for monitoring of behavior indicators. The obtained results were processed using an adequate statistical program. 1. In FST on the background of dexamethasone injection, the time of immobilization (p less then 0.01) was increased, the active swimming time (p less then 0.
