In connection with global climatic changes, which are accompanied by sharp temperature fluctuations, it is important to study the heat resistance of relict plants in order to improve the understanding of the mechanisms of adaptation and survival of organisms in these conditions. Identification of rare and useful plant species more resistant to high temperatures will make it possible to recommend them for use in landscaping, agriculture, medicine, and the like. The work was carried out on magnolias and ginkgo, since these plants are not only important for landscape design all over the world, but are also valued for the content of biologically active substances that are used in medicine and agriculture. Plants of Ginkgo biloba L., Magnolia obovata Thunb., Magnolia kobus DC. and Magnolia denudata Desr. warmed up for three hours at + 40 ° C, the control group was at + 26 ° C. The stress response was analyzed for the level of lipid peroxidation, superoxide dismutase and peroxidase activity, as well as the content of flavonoids and photosynthetic pigments in the studied plants. The photosynthesizing system of all studied species did not undergo any damaging effects due to the action of hyperthermia. Ginkgo biloba plants have shown very high resistance to high temperatures and stability of the antioxidant and pigment systems. Representatives of all the species of magnolia that we have considered can be positioned in the direction of decreasing resistance to sudden increases in temperature: Magnolia kobus → Magnolia obovata → Magnolia denudata. A higher resistance to hyperthermia was found in plants native to Japan. M. denudata was the least resistant species, possibly due to insufficient activity of antioxidant enzymes.

The work considers the causes of the coronary X syndrome development in women by assessing the experimental group and the control group with typical angina pectoris with angiographically altered vessels. Each group included 30 patients. When studingy medical records of the patients in the study group, we found out that in the reproductive period all of them had hyperestrogenemia, confirmed by the laboratory data, with the corresponding consequences in the form of various gynecological diseases, while the patients of the control group had unburdened gynaecological history. In terms of the lipid spectrum, the results turned out to be opposite. In the experimental group, the rates were within the normal range, and the control level of LDL-C significantly exceeded the required values. Despite the fact that estrogens increase the concentration of high density lipoprotein (HDL) in the blood and lower the content of low density lipoprotein (LDL) that are atherogenic, their surplus has a less negative effect than their lack, as the risk of developing atherosclerosis increases with decreasing concentration, and with an increase there is a risk of developing endothelial dysfunction, which provokes the development of coronary syndrome X. These date confirm the development of endothelial dysfunction in the patients of the experimental group with hyperestrogenemia in the history resulted from the impairment of the process of proliferation of endothelial cells with subsequent imbalance of secretion of biologically active substances. Among them, there is nitric oxide, which causes the relaxation of smooth myocytes, thus resulting in vasodilatation, and endothelins, providing the opposite, vasodilating effect. Prostacyclines and thrombomodulins secreted by the vascular endothelium in physiological conditions, counteract platelet aggregation. In the case of damage to the vascular wall, the production of prostacyclin and thrombomodulin is suppressed, but the release of thromboplastin, platelet activation factor and von Willerband factor activates that promote platelet aggregation and blood clotting. Under the participation of other physiologically active substances, selectins, endothelial cells promote adhesion to their surface and further penetration into the site of inflammation of neutrophils, blood acidophils. Selectin is accumulated in the cytoplasm of the endothelial cells in the form of specific electron-cellular inclusions, the so-called bodies of Weibel-Palade. Normally, vascular endothelium is impervious to blood components. However, being affected by a number of factors, and in particular histamine, endothelial cells lose contact with each other and decrease in number. This leads to the release of water and plasma proteins into the intercellular medium causing oedema. Due to the ability of the inner layer of vessels to produce a large number of biologically active substances, such changes can hardly be corrected by therapy.

Жизненно важными микроэлементами для жвачных животных являются медь, цинк, марганец, железо, кобальт, йод, селен. Микроэлементы, в которых атом металла соединён и защищён белковыми молекулами, улучшают воспроизводительные качества самок за счёт повышения оплодотворяемости, уменьшения эмбриональной смертности, улучшения состояния мочеполовой системы или повышения интенсивности функционирования яичников. Поэтому в настоящее время актуальными являются разработка и внедрение в технологию кормления сельскохозяйственных животных наиболее эффективных препаратов с необходимыми биологически активными веществами. На основании проведённого исследования дано практическое обоснование использования в технологии кормления тёлок отечественной кормовой биодобавки на основе гидролизата соевого белка, витаминов и микроэлементов. Установлено её положительное действие на некоторые функции органов и систем животных. Экспериментально доказана эффективность её применения для оптимизации обменных процессов и повышения воспроизводительных функций тёлок. Так, биохимическим исследованием образцов крови подопытных животных установлено, что количество кальция и фосфора в крови у тёлок опытной группы по сравнению с контролем было достоверно выше на 2,35 и 2,9% соответственно. Эритропоэтическая фракция была более выражена у молодняка опытной группы. У тёлок опытной группы время от начала скармливания препарата до первой выраженной охоты и осеменения, по сравнению с контрольными животными, сократилось на 16%, а период от начала скармливания препарата до плодотворного осеменения – на 25,7%. Количество тёлок, пришедших в охоту и осеменённых в первый месяц, в опытной группе по сравнению с контрольной было на 43% больше. Оплодотворяемость тёлок опытной группы за учётный период составила 95%, что на 20% больше, чем у животных контрольной группы. Включение в рацион тёлок биодобавки в дозе 100 мл/гол. позволило получить дополнительно на 8,5% больше валового прироста живой массы по отношению к их аналогам. The vital trace nutrients for ruminants are copper, zinc, manganese, iron, cobalt, iodine, selenium. Microelements in which a metal atom is jointed and protected by protein molecules improve the reproductive qualities of females by increasing fertility, reducing embryonic mortality, improving the state of the genito-urinary system or increasing the intensity of ovarian functioning. Therefore the development and implementation of the most effective preparations with the necessary biologically active substances in the technology of feeding farm animals is currently relevant. On the ground of conducted research a practical substantiation of the use of domestic food supplement based on the hydrolyzate of soy protein, vitamins and trace nutrients in the feeding technology of heifers is given. Its positive effect on some functions of animal organs and systems has been established. The effectiveness of its application to optimize metabolic processes and increase the reproductive functions of heifers has been experimentally proven. Thus a biochemical blood samples analysis of experimental animals found that the amount of calcium and phosphorus in the blood of the heifers of the experimental group compared with the control was significantly higher by 2.35 and 2.9% respectively. The erythropoietic fraction was more defined in the young experimental group. In heifers of the experimental group the time from the beginning of feeding the drug to the first defined heat and insemination compared with control animals decreased by 16% and the period from the beginning of feeding the drug to prolific insemination – by 25.7%. The number of heifers that came to the heat and inseminated in the first month in the experimental group was 43% higher than the control group. The impregnation capacity of the heifers of the experimental group during the record period was 95% which is 20% more than in animals of the control group. Inclusion in the diet of heifers bioadditive at a dose of 100 ml / goal allowed obtaining additionally 8.5% more the gross body weight gain relative to their analogs.

When balancing ration it is necessary to remember that the active factors of feeding are not the feed itself, but the content of nutrients and biologically active substances in them. It has been developed and physiologically justified feeding rations of cows during increasing the milk yield period, which are based on succulent feed, hay, grain and rapeseed presscake and a source of minerals and vitamins PVMA have been used. The experimental part of the work has been carried out in the winterstall period in the educational and experimental farm in the State Agrarian University of the Northern Trans-Urals. It has been found that from cows of the experimental group during the increasing the milk yield period 1503 kg of milk containing 3,98 % fat and 2,87 % protein has been obtained. Animals of the experimental group exceeded cows of the control group in milk yield by 90 kg (P > 0,95), in terms of fat and protein content in milk their superiority was 0,37 abs.% (P > 0,999) and 0,21 abs.% (P> 0,999). Input into the rations of lactating cows rapeseed presscake in the amount of 2 kg/ head/day and PVMA in the amount of 100 g during 3 months of lactation gives an increase in productivity for the entire lactation in the experimental group by 572 kg of milk with additional products by 2745,2 Rubles can be obtained more. The positive effect of the input of rapeseed presscake in the rations of lactating cows in the amount of 2 kg/head has been established/day and PVMA in the amount of 100 g in the period of following on the subsequent productivity of animals.

In the case of radicular syndrome in patients with dorsopathy, degenerative dystrophic changes, which contribute to the creation of additional mechanisms of pain impulse and chronization of the pathological process, are diagnosed in the deep muscles. The study included 40 patients with dorsopathy of the lumbosacral spine and radicular syndrome, with the average age of 45,3±1,5years, who were divided into 2 groups comparable in age and clinical and functional characteristics: the main group of 20 patients who were treated with laser phoresis of biologically active substances and the control group of 20 patients who received standard pharmacotherapy. As a result of the study, a significantly more pronounced improvement in the state of microcirculation in the paravertebral muscles when using phytoextracts laser phoresis was proved, which was confirmed by radiothermometry and transcutaneous oximetry. The analysis of radiothermometry and oximetry parameters obtained 3 months after the end of the course showed the stability of the therapeutic effect in 96% of patients in the main group, while in the control group, 50% of patients showed a regression of the effect obtained as a result of treatment. In longer terms, the therapeutic effect in 90% of patients of the main group was maintained for 9–12 months of follow-up, while in the control group — no more than 3–4 months.

Для интенсификации производства животноводческой продукции и повышения ее качества необходимо обогащать рацион сельскохозяйственных животных и птицы кормовыми добавками, содержащими комплекс биологически активных веществ. Исследованы образцы комплексной кормовой добавки, содержащей масляную композицию БАВ в-каротина, витаминов Е и С, жидкого рапсового лецитина и селена, и пробиотическую добавку (ПД) Целлобактерин в соотношениях соответственно от 1 : 1 до 1 : 5. Установлено, что при соотношении масляная композиция БАВ : ПД Целлобактерин 1 : 3 количество пробиотической культуры Enterococcus faecium 1-35, содержащейся в ПД Целлобактерин, в опытном образце достигает максимального значения 6,4 Ч 105 КОЕ/г. При этом обеспечивается равномерное распределение масляной композиции БАВ на поверхности ПД. В опытах in vivo определена эффективность применения комплексной добавки с установленным соотношением компонентов для нормализации обменных процессов в организме животных. Доказано, что введение в рацион лабораторных крыс опытной группы многокомпонентной кормовой добавки в количестве 3 к основному рациону (ОР), контаминированному микотоксинами, позволяет достичь опережения прироста массы тела на 15-е и 45-е сутки эксперимента на 6,45 и 33,05 соответственно снижения содержания мочевины в сыворотке крови на 58,43 по сравнению с аналогичными показателями у животных контрольной группы, получавших только ОР. Степень снижения аланинаминотрасферазы и аспартатаминотрансферазы по отношению к аналогичным показателям контрольной группы составила 18,53 и 29,89 соответственно. Следовательно, комплексная кормовая добавка при соотношении масляная композиция БАВ : ПД Целлобактерин 1 : 3 обладает ярко выраженными гепатопротекторными и антитоксическими свойствами. Enriching the diet of farm animals and poultry by feed additives containing a complex of biologically active substances is necessary to intensify the production of livestock products and improve their quality. Samples of a complex feed additive containing an oil composition of BAS в-carotene, vitamins E and C, liquid rapeseed lecithin and selenium, and a probiotic additive (PA) Cellobacterin in ratios from 1 : 1 to 1 : 5 respectively were studied. It was found that the ratio of the oil composition of BAS : PA Cellobacterin 1 : 3 respectively the amount of probiotic culture Enterococcus faecium 1-35 contained in PA Cellobacterin in the experimental sample reaches a maximum value 6,4 Ч 105 CFU/g. In this case, the distribution of BAS oil composition on the PA surface is uniform. The effectiveness of using a complex additive with a set ratio of components to normalize metabolic processes in animals was determined in in vivo experiments. It is established that introduction in a diet of laboratory rats of the experimental group multicomponent feed additive in an amount of 3 to the basic ration (BR), contaminated with mycotoxins, can achieve compared to the same indicators in animals of the control group who received only the BR, the timing of weight gain on 15-th and 45-th day of the experiment by 6,45 and 33,05 respectively reduction of urea content in blood serum at 58,43. The degree of reduction of alanine aminotransferase and aspartate aminotransferase in relation to similar indicators of the control group was 18,53 and 29,89 respectively. Therefore, a complex feed additive with the ratio of oil composition of BAS : PA Cellobacterin 1 : 3 has pronounced hepatoprotective and antitoxic properties.

In order to save the cost of expensive compound feed, a number of biologically active substances (vitamins and amino acids) and improve the digestibility of nutrients for the first time in poultry meat using laser technology there is a real possibility of “transferring” the studied amino acids (methionine, glycine) and all water-soluble vitamins using a laser beam through the skin in the breast area of broiler chickens. The research has been carried out in Belgrankorm-Veliky Novgorod LLC in the Krestetsky district in the Novgorod region with a large-cage housing method of broiler chickens of the cross Hubbard. The duration of broilers rearing was 39 days, 4 recipes of compound feed based on wheat grain, corn, soybeen meal with the inclusion of fish flour, sunflower oil, corn gluten, sunflower meal, meat and bone meal and mineral additives (monocalcium phosphate, lime flour) have been used. For better assimilation of nutrients and biologically active substances by the body amino acids (methionine, glycine) and water-soluble vitamins Undevit, both individually and in combination with them in a ratio of 1:1 (by weight), in the form of powders passed through an infra-red laser beam in a spatial modulator, which were attached to two emitters (simultaneously) of the “Uzor-2K-Super” laser in the chest area have been used. Broilers of the experimental groups ate feed more often and faster than the herdmates of the control group. Air ozonation in the poultry house and broilers has been carried out in a mobile way using the Rios ozonator of the Decont series (mode 3, with a capacity of 20 g/m3 ). Innovative methods of influencing on the body caused the increase in the intensity of metabolic processes, growth and development, fattening and meat traits, and feed conversion in broilers.

This paper presents the results of experimental studies the influence of biologically active substances of propolis on micromorphometric parameters of the ileum in young pigs. The results of the experiment make it possible to ascertain a change in the functional activity of the studied organ after the use of the drug from propolis. Since the most active process of absorption of monomeric hydrolysis products, especially amino acids and carboxylic acids, occurs in the ileum. Hydrolysis of intermediate products to monomers and preparation of the transition to absorption is carried out by enzymes fixed on the intestinal cell membranes. And the level of bioconversion of feed and retention of nutrients depends on their shape and structure, which ultimately affects the payment for feed with products. Therefore, the study of the histology of the small intestine and especially the ileum is of great importance. So, as a result of the study, it was found that the most characteristic histological changes in the structural components of the intestinal wall are observed in young animals of the experimental groups. The thickness of the main lamina of the mucous membrane of the ileum in piglets in the control group is 308.28 ± 2.81 µm, in piglets in the experimental group – 255.49 ± 0.75 µm. The height of the villi of the ileum, in the animals of the control group, is significantly lower and amounts to 193.89 ± 2.66 µm versus 280.97 ± 3.37 µm in the experimental group. Similar changes are observed in young animals of the older age group. The height of intestinal villi in pigs of the experimental group significantly exceeds the indicator of the control group and is 256.89 ± 1.62 µm and 163.96 ± 0.61 µm, respectively. The muscle plate of the intestinal mucosa of the pigs in the experimental group is significantly thicker than the control and is 17.8 ± 0.2 μm and 8.89 ± 0.08 μm, respectively. The obtained experimental material substantially supplements the information on the biological properties of propolis preparations. In practical veterinary medicine, research results can be taken into account when prescribing propolis for medicinal and prophylactic purposes. Since histological analysis of intestinal sections did not reveal destructive or pathological changes in any of the compared groups. In feeding, using the obtained practical material, we can specify the stimulating effect of the propolis preparation to intensify the growth of animals depending on the age of the pigs.

Effective Source

Numerous studies have shown that sapropel is an effective source of macro-and microelements, as well as biologically active substances. There are about 3 million lakes on the territory of Russia, where sapropel reserves are estimated at 250 billion tons. There are 497 lakes on the territory of the Tyumen region, the estimated reserves of sapropel in them are 1398,7 million tons. The Tyumen region is a biogeochemical province for all normalized trace elements. Biologically active compounds obtained from natural raw materials, including normalized trace elements in organic form are the most promising and safe. Under the inviroments of the Tyumen region, such natural raw materials can be sapropels. The study of the effectiveness of the use of sapropels and their influence on the metabolism and milk productivity of cattle is an urgent topic. The purpose of the research was to study the influence of sapropel lake Nepryak on milk productivity indicators and the biochemical composition of the blood of cows. For the experiment 3 groups of cows have been formed (a control group and two experimental ones) based on the principle of pairs of analogs. Cows of the 1st experimental group have been got in the ration of 300 g of sapropel per head/day, 2nd experimental – 500 g/head/day. Cows of the control group did not receive sapropel in the ration. It has been found as the result of research that the use of sapropel lake Nepryak in feeding of cows in doses of 300 and 500 g/head/day had the positive influence on their milk productivity. At the same time, it is most effective to feed sapropel at the dose of 300 g/ head/day.
