    The article reveals the results of orthopedic treatment of 57 people with extensive defects of dentition. Through comparative analysis, it was confirmed that the use of one-stage non-separable dental implants with immediate loading of nano-structural titanium in comparison with collapsible titanium screw implants reduces the frequency of periimplantitis after surgery and promotes better survival.В статье раскрыты итоги ортопедического лечения 57 человек с обширными дефектами зубных рядов. Посредством сравнительного анализа удалось установить, что использованиенеразборных дентальных имплантов с немедленной нагрузкой из наноструктурного титана марки в сравнении с разборными винтовыми имплантами снижает частоту периимплантитов после операции и способствует лучшей приживляемости

    During the examination of 105 patients with inflammatory periodontal diseases, a laboratory method was developed to assess the balance between proinflammatory and osteotropic mediators to characterize the severity and course of inflammatory-destructive changes in gingivitis and chronic generalized periodontitis (CGP). Depending on the periodontal lesion, three clinical groups were formed: group 1 (n=40) - patients with catarrhal and ulcerative gingivitis, group 2 (n=32) with mild chronic hepatitis С and group 3 (n=33) with moderate CGP. In patients with gingival fluid or in the contents of periodontal pockets (PC), the concentration of tumor necrosis factor alpha (TNF-a) was determined, osteotropic mediators - ligand of soluble activator of nucleation factor Kappa В (sRANKL) and osteoprotegerin (OPG) by the immunoassay method. In patients with mild to moderate CGP, close links were established (p<0,0001) of the values of periodontal indices characterizing osteodestruction with the content of TNF-a, sRANKL and osteoprotegerin in PC fluids. In patients with formation of CGP, as well as increasing the severity of periodontal lesions in the gingival fluid, the concentration of TNF-a, sRANKL increases and the content of osteoprotegerin decreases. The change in the concentration of osteotropic mediators in the PC fluid occurred before the osteolysis in the periodontium was formed. In patients with mild CGP, a decrease in the concentration of OPG (p<0,05) and an increase in the content of sRANKL (p<0,05) in the gingival fluid relative to the norm requires active x-ray control of osteoresorption.При обследовании 105 больных с воспалительными заболеваниями пародонта разработан лабораторный способ оценки баланса между провоспалительными и остеотропными медиаторами для характеристики тяжести и течения воспалительно-деструктивных изменений при гингивите и хроническом генерализованном пародонтите (ХГП). В зависимости от поражения пародонта формировали три клинические группы: 1 группа (n=40) - пациенты с катаральным и язвенным гингивитом, 2 группа (n=32) - с ХГП легкой и 3 группа (n=33) с ХГП средней степени тяжести. У пациентов в десневой жидкости или в содержимом пародонтальных карманов (ПК) определяли концентрацию фактора некроза опухоли-альфа (ФНО-α), остеотропных медиаторов - лиганда растворимого активатора фактора нуклеации каппа В (sRANKL) и остеопротегерина (ОПГ) иммуноферментным методом. У пациентов с ХГП легкой и средней степени тя­ жести установлены тесные связи (р<0,0001) величин пародонтальных индексов, характеризующих остеодеструкцию, с содержанием в жидкости ПК ФНО-α, sRANKL и остеопротегерина. У больных при формировании ХГП, а также при усилении тяжести поражения пародонта в десневой жидкости повышается концентрация ФНО-α, sRANKL и снижается содержание остеопротегерина. Изменение концентрации остеотропных медиаторов в жидкости ПК наступало раньше, чем формировалась остеодеструкция в пародонте. У пациентов с ХГП легкой степени тяжести снижение концентрации ОПГ (р<0,05) и повышение содержания sRANKL (р<0,05) в десневой жидкости относительно нормы требует активного рентгенологического контроля остеорезорбтивных процессов

    მსოფლიო საზოგადოებისათვის მთავარი ეკოლოგიური გამოწვევა „სუფთა წყალი“ საქართველოსთვისაც ერთობ აქტუალური საკითხია. ჩვენი ქვეყანა რამდენადაც მცირე მდინარეთა სიუხვით გამოირჩევა, იმდენად გამორჩეულია მათი დაბინძურების კერების რაოდენობით. ამ კუთხით არც აჭარის რეგიონია გამონაკლისი, როლის მთელ ტერიტორიაზე მიმდინარეობს წყლის წყაროთა შესწავლა. დღეის მდგომარეობით შესწავლილი 150-ზე მეტი ზედაპირული მდინარე თუ ნაკადული, რომელთაგან თითქმის მესამედში საყოფაცხოვრებო ნარჩენების ნაგავსაყრელის, ხოლო ნახევარზე მეტში ბაქტერიოლოგიური დაბინძურების პოვნა მოხდა. მოცემული თემა სწორედ ამ დაბინძურების კერების აღმოჩენით სამუშაოებს შეეხება."Clean water", the main environmental challenge for the world community, is also an urgent issue for Georgia. As much as our country is distinguished by the abundance of small rivers, it is distinguished by the number of their pollution centers. In this regard, the Adjara region is no exception, water sources are being investigated in the entire territory of the region. To date, more than 150 surface rivers or streams have been studied, in almost a third of which a landfill of household waste was found, and in more than half, bacteriological pollution was found. This topic will concern the work of finding these pollution centers

    Young children's evaluations of the ingroup and of outgroups: A multi-national study

    No full text
    In investigating intergroup attitudes, previous research in developmental psychology has frequently confounded ingroup favouritism and outgroup derogation. The present study, using unconfounded measures, examines the possibility that ingroup favouritism and outgroup derogation are distinct phenomena. Six-year-old children (n=594) from five, culturally diverse nations were asked to make various evaluations of the national ingroup and of four national outgroups. The data indicate that although there is overwhelming evidence that young children favour the ingroup over other groups, outgroup derogation is limited in extent and appears to reproduce attitudes held by adult members of the particular nations investigated
