Interdependence of processes of lipid peroxidation and antioxidant protection in animals of different age in case of polytraumaThe experiment model of polytrauma of animals 3, 6, 24-month old was conducted according to the method of A.A. Hudyma. The research was conducted after 1, 3, 24 hours and for 14 days after modulation of polytrauma. The activity of processes of lipid peroxidation was judged by the content of TBK-active products. Activity of superoxide dismutase, catalase and the content of ceruloplasmin was determined by biochemical methods. Statistic processing of material was carried out by parametric methods. The analysis of the relation-ship between the two features in the presence of a normal distribution was estimated by the results of the corre-lation analysis by Pearson. We have established the relationship between lipid peroxidation and AOS in three-month young rats in the early stages after the polytraumatic modeling. At 1, 3 and 24 hours after the polytrau-matic modeling, lipid peroxidation indexes increased and enzymes of AOS were activated. In late terms after the modeling of polytrauma (14 days) in animals of 3 months old AOS protection was absent by the established direct strong correlation between the activity of SOD of the liver and blood CP (r= 0,73, р0,05). In 6 and 24-month old rats, after 1, 3, and 24 hours after polytraumaticsmodeling, there were found inverse statistically significant correlation connections between MDA level and AOS indicators. In the late stages of the modeling of polytrauma of animals of 6 and 24 months old there was a depletion of enzymatic link of AOS on the back-ground of high content of MDA. The increase of intensification of lipid peroxidation processes leads to a de-crease in the adaptation resources of AOS in animals of different age groups with polytrauma and vice versa, increase in exhaustion of the AOS potential leads to activation of lipid peroxidation which induces peroxidation processes in polytrauma. It predicts the progressing of misbalance in antioxidant system in injured animals in different terms of polytrauma.

Водные брюхоногие моллюски Узбекистана как промежуточные хозяева гельминтов человека и животныхИзучение водных моллюсков Узбекистана как промежуточных хозяев гель-минтов человека и животных. Материал и методы исследования. Изу-чены брюхоногие водные моллюски из семейств Lymnaeidae, Planorbidae, Horatidae, Mela-noididae, собранные из различных типов водоёмов Узбекистана. Зараженность моллюсков партенитами трематод определяли путем специальных систематических, малокологи-ческих и гельминтологических исследований, проведенных за 1986 – 2009 годы. Всего собрано и обработано 3 тысяч моллюсков из различных территорий Узбекистана.

Improvement of the method for isolating cholesterol from animal brain tissueCholesterol and its derivatives are used in the production of liquid crystals, in pharmacology as a component of dosage forms and diagnostic tools, as a precursor to steroid drugs. Cholesterol in the composition of the cell plasma membrane plays the role of a bilayer modifier, giving it a certain stiffness due to an increase in the density of the "packing" of phospholipid molecules. In this work, an improvement is made in the technology for producing cholesterol from biological material

Theoretical background of the endemic icteroghemoglobinuria of the karakul sheepIt is known that in Uzbekistan there are widespread violations of the copper metabolism of Karakul sheep associated with both a deficiency and an excess of this element in their body. Both of these types of impaired copper metabolism are accompanied by serious pathological deviations, leading to a decrease in the productivity of Karakul sheep and often to their death. In Southwestern Kyzilkum, Karakul sheep constantly has a disease with signs of jaundice and blood urine

В патогенезе сосудистых изменений не всегда учитываются нарушения венозного кровообращения. При нарушении кровообращения по магистральным венам, развивается, с одной стороны, затрудненный венозный отток, с другой - усиленный приток, что со временем приводит к формированию венозной гипертензии -
Морфология клеток диффузной эндокринной системы тонкой кишки животных с сенильным остеопорозомЦель исследования. Изучение морфологических и морфометрических показателей клеток диффузной эндокринной системы тонкой кишки и степени минерализации бедренной кости у кроликов и морских свинок старческого возраста. Материал и методы исследования. Изучена тонкая кишка у 5 крольчих 6-7-летнего возраста и у 6 морских свинок-самок 5-6-летнего возраста. Криостатные срезы из нефиксированного материала обработаны раствором глиоксиловой кислоты, парафиновые срезы окрашены гематоксилином и эозином, по методу Ван- Гизона и импрегнированы азотнокислым серебром по Гримелиусу. Степень минерализации бедренной кости определяли сравнением веса золы после сжигания ее к первоначальному весу костей в процентах. Плотность распределения эндокринных клеток определяли точечным методом на стандартной площади. Результаты. Установлено достоверное уменьшение числа (плотность распределения) эндокринных клеток слизистой оболочки и снижение степени минерализации бедренной кости у старых крольчих и морских свинок - самок. Обнаружены дегенеративные изменения некоторых эндокринных клеток в виде вакуолизации их цитоплазмы и снижения степени флюоресценции эндокринных клеток открытого типа старых лабораторных животных. Заключение. В стенке тонкой кишки старых крольчих и морских свинок - самок происходит уменьшение плотности распределения, снижение степени флюоресценции эндокриноцитов и степени минерализации бедренной кости. Отмечается параллелизм между изменением числа эндокринных клеток стенки тонкой кишки и минерализацией бедренной кости.

Морфология эндокриноцитов тощей кишки крольчат в период раннего постнатального онтогенеза при различных способах гистологической обработки материала в норме и в эксперименте
Doctor's HeraldОдним из продуцентов биогенных аминов, которые играет важную роль при регуляции функций внутренних органов, является эндокриноциты (апудоциты, клетки дисперсной эндокринной системы). Располагаясь одиночно в составе эпителия этих органов, они вырабатывают биогенные амины и пептидные гормоны, которые участвуют в паракринной и эндокринной регуляции функций (7,8), а также в межорганных взаимодействиях различных отделов пищеварительного тракта, как в норме, так и при экспериментальных воздействиях (1,2,3,6)

Enriched feed: non-traditional use of raw materials for poultry
Green chemistry and sustainable developmentIt is known that up to 70% of feed costs in the poultry industry are accounted for by cereal crops, including wheat, barley and corn. These cereals are essential in the sphere of feeding the population and occupy the main position among food crops. The search for new types of grain fodder to partially replace traditional and use them to maintain and increase the productivity of poultry is urgent.
