The aim of the study was to compare the cephalometric and somatometric parameters of boys and girls aged 18-20 to reveal features of the anthropometry of the youth population of the Omsk city.Material and methods. There was performed an anthropometric examination of 140 people aged 18 to 20 years (70 boys and 70 girls), Slavic ethnic group. Height, transverse chest diameter, chest circumference, body weight, longitudinal and transverse dimensions of the head, full face height, and zygomatic diameter were measured. To obtain generalized data indices of Rees-Eysenck, Rohrer, Quetelet II, Pignet, the head index and the facial index according to Garson were calculated. The data obtained were statistically processed.Results. According to our data, the average height of boys was 180,49±0,73 cm, body weight – 77,28±1,65 kg, average height of girls – 165,79±0,79 cm, body weight – 59,25±1,15 kg. Normosthenic type (44%) prevailed in boys, and asthenic (53%) somatotype prevailed in girls (according to the Rees–Eysenck index). Individuals of both sexes were more likely to have harmonious (57 and 72%, respectively) physical development (according to the Rohrer index). According to the M.V. Chernorutsky index, hypersthenic (44%) somatotype prevailed in boys, and normosthenic (66%) somatotype prevailed in girls. Cephalometry demonstrated that mesocephalic head shape (54%) was more commonly determined in boys, and brachycephalic (50%) head shape - in girls, while euryprosopia was typical for people of both sexes (50% of cases in boys and 63% in girls).Conclusion. The study determined and evaluated typical features of anthropometric data (head shape, face, somatotype) of boys and girls aged 18 – 20 years of the Omsk city.
Омский государственный медицинский университет, Омск, РоссияАннотация. Цель исследования -выявить особенности взаимосвязи между параметрами кефало-и соматометрии и показателями телерентгенограмм головы (в боковой проекции) для оценки их влияния на форму лица.Материал и методы. Проведено антропометрическое исследование головы и тела у 70 юношей и 70 девушек. Для получения телерентгенограмм головы в боковой проекции 39 юношей и 39 девушек (из числа обследованных и на основе их информированного согласия) прошли рентгенологическое обследование на компьютерном томографе Planmeca ProMax 3D (Финляндия). Кефалометрический анализ полученных снимков осуществляли при помощи онлайн-сервиса Mave Cloud. Количественные данные подвергали статистической обработке в программе Statistica 6.0.Результаты. Установлены половые различия значений (p<0,05) для следующих параметров: длины переднего основания черепа по Bjork, передней высота лица, длины тела нижней челюсти по Jarabac, высоты ветви нижней челюсти, длины заднего основания черепа, задней высоты лица, длины переднего основания черепа по Schwarz, длины нижней челюсти, длины верхней челюсти, толщины мягких тканей в области подбородка на отрезках Me-me, Gn-gn, Pog-pg. Выявлена прямая умеренная связь между значениями межчелюстного угла и скулового диаметра, с одной стороны, и формой лица -с другой стороны (p<0,05).Заключение. Ряд линейных параметров боковых телерентгенограмм имеют половые и региональные особенности. Кроме того, показатели телерентгенограмм и соматотип оказывают влияние на форму лица, что необходимо учитывать при коррекции окклюзии и эстетики лица в практике врача-стоматолога.Ключевые слова: телерентгенография, антропометрия, юноши и девушки ОмскаКонфликт интересов: авторы заявляют об отсутствии конфликта интересов.
PURPOSE: to evaluate experimentally the features of structural and functional changes in lymphoid organs under the conditions of oral administration of high doses of sodium selenite and after its termination. MATERIAL AND METHODS. The study was conducted on 30 sexually mature male Wistar rats, weighing 200-220 g. The morphometric research of the thymus, group lymphoid nodules, mesenteric lymph nodes, spleen, and laboratory investigation of blood were performed. The animals were divided into 3 groups depending on the nature of the study. The first (control) group consisted of intact rats. Animals of groups 2 and 3 were orally administered sodium selenite, at a rate of 5 mg/kg of mass for 5 days. Morphofunctional studies of lymphoid organs in group 2 were performed on day 6, in group 3 – on day 14. RESULTS. The degree of severity and directional effect of structural and changes are determined by the functional specialization of the studied organs. CONCLUSION. Signs of endotoxicosis indicate evident structural and functional changes in the lymphoid organs after five times administration of sodium selenite. Canceling the administration helps to improve the organism's reserve capacity and adapt to altered metabolic processes.
