Ultrasonic extraction of flax polysaccharides

To date, flax is one of the most promising crops that are dynamically developing. The demand for flax and products of its processing in Ukraine and other countries is due to increased interest in its use in medicine, cooking and cosmetology [1]. The main nutrients that determine the biological activity of flaxseed are protein substances, vitamins, enzymes, carbohydrates and fatty oils, which include glycerides of linoleic (35-45%), linoleic (25-35%), oleinic (15-20% ), stearic acid (8-9%). In our time, from flax seeds on an industrial scale only oil is obtained, using one of the traditional mechanical methods. According to the biological value, oil from flaxseed oil occupies the first place among other edible vegetable oils and contains a lot of substances useful for the body (polyunsaturated acids, vitamins F, A, E, K, saturated fatty acids (10% composition). Flaxseed oil is excellent a source of valuable polyunsaturated fatty acids ω-3 and ω-6 (the human body can not independently synthesize these valuable acids). The aim of the work is to study the methods of obtaining and application of flax polysaccharides, as well as the development of energy-efficient technology for their obtaining. The conducted researches have shown, that at application of ultrasonic processing in the process of extraction of flax polysaccharides the extraction time is significantly reduced. The maximum yield of polysaccharides takes place with ultrasound processing of extraction capacity of 70 W / m2 for 20 minutes. The flax polysaccharides obtained in this way can be successfully used as antioxidant, bactericidal, fungicidal and antiviral drugs

Ultrasonic extraction of amaranth oils

The isolation of biologically active substances - extraction, is currently the most difficult and time-consuming task that can be solved only in the conditions of large productions with the help of specialized equipment, and practically impossible at home. As numerous studies show, from the natural raw material of plant and animal origin it is possible to extract practically all known compounds, which are produced by plants [1]. The authors carried out extraction of amaranth in cold pressed olive oil. Since it is close in composition with amaranth oil. The biological activity of the oil is due to the presence of squalene and tocotrienol, and the percentage of their various fractions possessing antioxidant properties

Mechanism of adhesion of glass monomeric cements of Meron and Total-cem to dentin

Recently, researchers note an increase in the prevalence of non-carious lesions of solid dental tissues. The forms of non-carious lesions of teeth are described: erosion and abrasion, wedge-shaped defects and erosion, which were previously practically not met. Increasing the life expectancy and maintaining natural teeth also led to the fact that clinicians often began to meet with patients with increased erosion of teeth. Study of the mechanism of adherence of glass-like cements to dentin is very important. In our case, the adhesion of our cements to dentin and enamelabs of acid protrusion, in our opinion, is provided by two mechanisms. The first of these is based on the fact that carboxylate groups of the macromolecules of polyacrylic acid are capable of forming chelating compounds with calcium, in particular calcium hydroxyapatite dentin and enamel. The second possible mechanism of communication is based on the affinity of polycarboxylic acids to nitrogen of protein molecules, in particular, collagen, which is manifested by the absorption of polyacrylic acid on collagen dentin

Study of adhesion of "MERON" and "TOTAL-CEM" cements to dentine, cyscium chlorine and dioxide alloy

Analysis of literature data shows that glassless cements of Méron and Total-cem are now widely used in dentistry to fix dental tabs [1]. Therefore, the study of the adhesion of these cements to the dentin and to the inserts of the KHS and zirconium dioxide is very relevant. The authors investigated samples that were obtained by removing single-channel teeth. Then the root canals were subjected to endodontic machining with the subsequent calibration of the rows of the corresponding pin diameter. The results of the conducted studies allow us to conclude that for fixing the inserts from the KSS alloy, it is more expedient to use MERON cement, and for carbide total-Cem carbide inserts from zirconium dioxide

Use of modern educational technologies and standardization of control by the department of general dentistry of OMU IHU in order to improve the quality of training of dentists

In the implementation of the strategy of Ukraine's integration into the European Union, one of the directions of the higher educational establishments in general and higher medical educational institutions in particular is the introduction of a system of integrated licensed examinations with a university-independent assessment of knowledge according to state standards. The results of the licensed exam allow you to get an objective picture of the level of theoretical training of graduate students, and the integral exam Krok-2 is a progressive form in the work of a higher medical school. The authors cover aspects of improving the educational process at the Department of General Dentistry. The implemented methods of teaching allowed to combine theoretical training of students for the practical training of their practical skills; made more interesting and clear independent non-auditing work of students; gave teachers the ability to control the quality of this work. It allows to improve the quality of preparation of students-dentists both for final examinations, and for the further professional activity

Clinical substantiation for a new method for prevention and treatment of prosthetic stomatitis with edentulous jaws

In clinical testing method we have 36 people with complete maxillary defects with metal prostheses in the mandible. In most cases, patients have acrylic dentures. Patients were divided into two groups: the first group there were produced traditional dentures, with no prevention for the abovementioned method, the second group comprised patients who were produced a modified prosthesis with prophylactic use of Amaranth Oil for 1 month. We conducted two studies. The first concerned the definition of quality prosthetic method for determining the frequency of corrections and research strength of fixation of prostheses, which were determined through a survey of the patient subjectively and objectively determined and manipulative way of three stages: very good, good, poor. The corrections analysis of prostheses in the first group has shown that at the traditional technology 62.5% of patients needed the third and more corrections. Complete adaptation to the prosthesis without complaints of painful sensations when a correction was observed only in 25.0% of the first group of patients. Due to the original denture with complete prosthesis with using polystyrene grid, with its help the sysem of microchannels for the drugs application, such as Amaranth oil, makes it possible to achieve painless effective treatment of prosthetic stomatitis, provides comfort of use of removable dentures and economic feasibility.Приводится вариант решения проблемы профилактики и лечения протезных стоматитов, возникающих при пользовании полными съемными акриловыми протезами. Авторы предлагают модификацию базиса протеза с целью создания депо лекарственного вещества — амарантового масла с содержанием сквалена 7,5 %. При длительном пользовании данным методом профилактики авторы исследования выявили снижение показателей, свидетельствующих о воспалительном состоянии слизистой оболочки полости рта

Morphological study of changes in tissues of experimental animals with implanting various structural materials

Проведенные морфологические исследования на экспериментальных животных показали, что при вживлении сплавов металла и керамики под кожу крыс наблюдаются дистрофические изменения в эпителии и дерме. Уровень этих изменений различен: при вживлении металлов он значительно выражен, поражены окружающие сосуды, наблюдаются клеточные дегенеративные изменения. При вживлении керамики выраженность процессов незначительна.Morphological studies conducted in experimental animals have shown that during implantation of metal alloys and ceramics under the skin of rats there were observed degenerative changes in the epithelium and the dermis. The level of these changes is different: with implanted metal it is significantly pronounced, surrounding vessels are damaged, there are cellular degenerative changes. When implanting ceramic, the process is less pronounced

Особенности течения протезных стоматитов при использовании различных базисных пластмасс у больных с метаболическим синдромом

Метою цього дослідження є вивчення патогенетичних особливостей розвитку ПС і стану місцевої резистентності при застосуванні різних базисних пластмас у пацієнтів із МС.Features of prosthetic stomatitis progress while using different plastic bases in the patients with metabolic syndrome L. D. Chulak, D. О. Yakimenko The state of local resistance of the mouth in the patients with the prosthetic stomatitis with the metabolic syndrome background and its dependence on the basic plastic, used in the dentures, has been studied. It has been demonstrated that the patients with prosthetic stomatitis with the metabolic syndrome have higher salivation rate and higher pH value of the saliva while using “Pro Base Hot”, as well as higher activity of local resistance, providing for better antimicrobeal protection. “Ftorax” usage caused higher activity of neutrophiles, providing better antifungal protection. Key words: prosthetic stomatitis, metabolic syndrome, local resistanceИзучали состояние местной резистентности ротовой полости у больных протезными стоматитами на фоне метаболического синдрома в зависимости от вида базисной пластмассы, использованной для протезирования. Показано, что у больных протезными стоматитами на фоне метаболического синдрома при использовании базисной пластмассы “Pro Base Hot” наблюдается более высокая скорость саливации и рН слюны, активация звеньев местной резистентности, обеспечивающих противомикробную защиту. При использовании базисной пластмассы «Фторакс» отмечалась более выраженная активация нейтрофилов, обеспечивающих противогрибковую защиту. Ключевые слова: протезные стоматиты, метаболический синдром, местная резистентность
