СРАВНИТЕЛЬНАЯ ХАРАКТЕРИСТИКА РАЗЛИЧНЫХ МЕТОДОВ ОПЕРАТИВНОГО ЛЕЧЕНИЯ СПАЕЧНОЙ КИШЕЧНОЙ НЕПРОХОДИМОСТИ У ДЕТЕЙ

The authors analyzed the results of treatment of 122 children with acute adhesive intestinal obstruction. By type of surgical treatment were identified: the first group - 85 patients who were previously operated with laparotomy access; the second group - 37 patients who were previously operated with laparoscopy. It was found that the use of laparotomy in children is traumatic, lead to inflammation and worsening of adhesions in the abdominal cavity, extend rehabilitation period, the flow of endogenous intoxication and increase percentage of complications (35.71%). Application of laparoscopy reduces complication rate in 3 times, reduces the time spent in the hospital in 1.6 times, reduces the number of relapses in 6.5 times.Авторы проанализировали результаты лечения 122 детей с острой спаечной кишечной непроходимостью. По виду оперативного лечения были выделены 1-я группа - 85 больных, которые ранее были оперированы лапаротомным доступом, и 2-я группа - 37 больных, которые ранее были оперированы лапароскопически. Выявлено, что использование лапаротомного доступа у детей травматично, усугубляет воспалительный и спаечный процессы в брюшной полости, способствует более длительному реабилитационному периоду, течению эндогенной интоксикации и большей доле осложнений (35,71%). Применение видеоэндолапароскопии позволяет снизить процент осложнений в 3 раза, уменьшить время, проведенное в стационаре, в 1,6 раз, а количество рецидивов - в 6,5 раз

The effect of Bacillus subtilis GM2 and GM5 probiotics on the growth and fodder digestibility of broiler chickens

The probiotic properties of the Bacillus subtilis GM2 and GM5 strains were studied on 90 Cobb 500 broiler chickens aged one day that were randomly divided into three groups: the control group with the standard diet and two experimental groups (30 chickens per group) with the diet supplemented with B. subtilis GM2 (group 1) and GM5 (group 2) spores. The addition of B. subtilis GM2 and GM5 spores at a concentration of 1·107 CFU/g to the ration of broiler chickens improved their growth rate, as well as increased the digestibility of nutrients and modulated the intestinal microflora in them. The use of probiotics stimulated an increase in the live weight of chickens by 6.30% and 13.78% (p = 0.05) as compared with the control group. The average daily weight gain in experimental groups 1 and 2 amounted to 52.82 ± 0.36 g and 56.54 ± 0.47 g per chicken, which is more than in the control group (49.69 ± 0.40 g) – by 6.30% and 13.79% (p = 0.05), respectively. The administration of probiotics by feeding favored an increase in the population of lactic acid bacteria in the small and large (to a lesser extent) intestine – bacteria belonging to the Enterobacteriaceae, Lactobacillaceae, and Clostridiaceae families were isolated from the intestinal contents and identified. The veterinary-sanitary examination found that the meat of broiler chickens from the experimental groups meets all the GOST requirements for organoleptic, physico-chemical, and bacterioscopic characteristics. Thus, probiotics based on the B. subtilis GM2 and GM5 strains have a positive effect on the growth and fodder digestibility of broiler chickens

Overview of the geometries of shape spaces and diffeomorphism groups

© Springer Science+Business Media New York 2014. This article provides an overview of various notions of shape spaces, including the space of parametrized and unparametrized curves, the space of immersions, the diffeomorphism group and the space of Riemannian metrics. We discuss the Riemannian metrics that can be defined thereon, and what is known about the properties of these metrics.We put particular emphasis on the induced geodesic distance, the geodesic equation and its well-posedness, geodesic and metric completeness and properties of the curvature
