The Ellipin, derived from bovine liver, is a newly developed agent containing several important fattyacids and may have anticancer effects on cancer cell in vitro culture. This Ellipin preparation containmany PUFAs and those are important molecules for membrane order and function; they can modifyinflammation-inducible cytokines production, eicosanoid production, plasma triacylglycerol synthesisand gene expression. Recent studies suggest that anti-proliferation effect on in vitro cancerous cell linese.g. J62, Raji, Hela, K582, and in vivo it minimized and decreased the growth of U14 cervical cancer inmice and suppressed the growth of its S37 sarcoma cells, increased the area of dead cancer cells, anddecreased the angiogenesis. Also it can be cancer chemopreventive and auxiliary agents for cancertherapy. The Ellipin could alter cancer growth influencing cell replication, cell cycle, and cell death.However, the effects of the Ellipin function on tumor growth in vivo have not been studied completlyand the mechanisms remain unclear. The question that remains to be answered is how, which pathwayEllipin can affect so many molecular ways inside cancer cell. We hypothesize that Ellipin’s mixture ofunsatured fatty acids effect inductor molecules in cancer gene which inhibits a repressor protein bindingto promotor and synthesis signaling molecules (caspase protein, TNF- ¹) in liver cancer cell. Also italter membrane stability and modifing cellular signalling.

IntroductionSea buckthorn is known to be one of the vitamin-rich berries in the plant kingdom and has beencredentialed as highly valued for healthy living, improving well-being, enhancing lifestyle, and preventingthe disease. Widely recognized in Northern regions of Europe and Asia, Hippophae rhamnodes hasbeen used medicinally for thousands of years. Both of seed and pulp oil have tocopherols, carotinoids,as well as ω-3 and ω-6 fatty acid families. The seed oil is highly unsaturated, with proportions of linoleic(C 18:2n-6) and α-linolenic (C18:3n-3) acids between 30-40% and 20-35%, respectively, whereas thepulp oil is more saturated containing high amounts of palmitoleic (C16:1n-7, 16-54%) and palmitic acids(16:0,17-47%). Many researchers including Laagan B., Avdai Ch., Tsendeekhuu Ts., Vernik S. R.,Jamyansan Y., Badamkhand D., Odonmajig P have determined content of berry, fatty acid compositionof sea buckthorn pulp and seed oil since 1970 in Mongolia. However, total fat and fatty acids compositionof Hippophae rhamnodes general is known, limited reports exist dealing with comparative differencesin fatty acid composition of Hippophae rhamnodes grown in Mongolia. Therefore, we analyzed thecomposition of fatty acids pulp oil and seed oil in sea buckthorn grown in Mongolia.Materials and MethodsPulp and seed oil were produced in Monos Food Co Ltd., and fatty acid methyl ester were analyzedusing Agilent Packard Gas Chromatograph (GC) (Model HP-6890 Agilent Packard) with mass-spectrumdetector (Model HP MSD 5973N).ResultThe results indicated that unsaturated fatty acids in the seed oil (85.4%) and in pulp oil (62.5%) arehigher than saturated fatty acids of seed oil (14.6%) and pulp oil (37.1%) respectively. The mostimportant factor defining the nutritional value of oil is ratio of unsaturated fatty acids present in oil. Theseed oil contains palmitic acid (10.8%), oleic acid (20.3%), limoleic acid (42.9%), α-linolenic acid (5.6%),Eicosadienoic acid (14.7%). Pulp oil of Hippophae rhamnodes has palmitic acid (35.4%), palmitoleicacid (38.5%), oleic acid (including Vaccenic acid) (6.6%) and linoleic acid (10.4%). The palmitic acid andpalmitoleic acid ratio in pulp oil was more than in seed oil. While oleic acid, linoleic acid and α-linolenicacid in seed oil have a higher ratio than that of pulp oil. It shows that unsaturated fatty acids in seed oilare much higher than pulp oil.ConclusionUnsaturated fatty acids in the pulp oil contain 62.5%, including essential fatty acid ω-3, 6, 9 (18.2%);it is content of 29.12% in unsaturated fatty acids. While, unsaturated fatty acids of seed oil contains85.4% in total fatty acid and essential fatty acid contains 96.72% in unsaturated fatty acid. It can thus beconcluded that seed oil is better than pulp oil because the former contains essential fatty acid.

Background In the present work, a reverse – phase high –performance liquid chromatographic procedure has been developed for the determination of vitamin E in cereals. The sample treatment was done by Sohhlet extraction procedure with a water bath. Afterwards, vitamin E was analyzed by HPLC on a Discovery C 18 (250 x 4.6 mm, 5 mm) analytical column, using a solution of methanol: water (95:5, v/v) as mobile phase. The UV-Vis detection of vitamin was made at 210 nm for all samples and fl ow rate was adjusted at 0.8 ml.min-1. Among grain-cereal products, average content of vitamin E were determined in kamut, špaldove kernotto and špalda loupana, namely 1.19, 1.19 and 1.30 mg.100g-1. Keywords: vitamin E, HPLC, cereal INTRODUCTION Vitamin E is a fat soluble vitamin, being well presented in vegetables, fruits, seeds, nuts (Bramley et al., 2000). Cereals are one of the important sources of lipids as well as a good source of vitamin E. Several studies have been investigated that presences of numerous antioxidant compounds in two specifi c food groups, the carotenoids and the vitamin E contributes signifi cantly in disease prevention ( Palozza & Krinsky, 1992, Halliwell et al.,1995, Andlauer & Fürst, 1998 ). Biological activities of vitamin E vitamers generally believed to its antioxidant action by tocopherols. Specially, α-tocopherol has been labeled as most effi cient antioxidant for lipid peroxidation in biological membranes (Traber & Atkinson, 2007). Vitamin E is not synthesized within a human body, and must be supplied in the diet. More data on vitamin E contents in cereals and other foodstuffs are needed, however, since they have been investigated with modern, reliable analytical methods in a few studies (Panfi li, 2003, Sundl et al., 2007). Due to the reason many researche have been performed to develop a simple and sensitive determination method for vitamin E and other fat soluble vitamins in foods. Several HPLC methods for determination of vitamin E are described in the literature, as well as methods its vitamers simultaneous determination (Lang et al., 1992, Luque-Garcia, 2001, Escriva´ et al., 2002). The aim of this study was to develop a normal phase HPLC method for a fast and reliable determination of vitamin E of cereals. Therefore, it was to investigate the precision of calculatedvitamin E content of cereals. MATERIAL AND METHODS Chemicals. D, L-α-tocoferol and - were from Fluka (Sigma-Aldrich Co, Germany). Methanol (purity: 99.8%) was obtained from Sigma-Aldrich (Germany). All other reagents were analytical grade and were purchased from Petr Lukes (Uhersky Brod, Czech Republic). Samples. For this analysis were chosen following cereals grown in organic farming: Kamut, Špaldove kernotto, Grünkern and Špalda loupaná. Individual samples were delivered directly by the manufacturer PRO-BIO, Ltd., (Staré Město Sněžníkem, Czech Republic). Cereals products stored in the original container in a dark place at room temperature and not more than 4 months after packing.

IntroductionA hangover is the experience of various unpleasant physiological and psychological effects followingconsumption of alcohol beverages, which can last for more than 24 hours. Common symptoms ofhangover are headache, gastrointestinal complaints, sweating, hyper-excitability, dry mouth, anorexia,diarrhea, dizziness, fatigue and vertigo. Alcohol or ethanol gets metabolized to an intermediate product,acetaldehyde, by the enzyme alcohol dehydrogenase (ADH), and then acetaldehyde is converted toacetate by a second enzyme aldehyde dehydrogenase (ALDH). Acetaldehyde causes toxic effects,such as high pulse, rate, sweating and vomiting. In most people, ALDH metabolizes acetaldehydequickly and effi ciently, so that this intermediate metabolite does not accumulate in high concentrations.Many treatments are described to prevent hangover, shorten its duration, and reduce the severity of itssymptoms, including innumerable folk remedies and recommendations.GoalThis study was conducted to investigate whether anti-hangover preparation has a protective effectagainst acute alcohol induced hangover in Wistar rats.Materials and MethodsMale and female Wistar line rats, weighing 180-210g were used for hangover model or ethanolmetabolism experiment. Rats were administered orally ethanol as 38% aqueous solution with feedingneedle, 1 ml/200g body weight. The anti-hangover preparation was administered 1 hour before ethanolconsumption. Blood was collected from the tail vein for the measurement of serum acetate andacetaldehyde at just before and 8, 16, 24 hour after ethanol administration.Statistical analysis: All value expressed as mean S.E obtained from n number of experiments.ResultFrom this study results summarize that the anti-hangover preparations decreased blood serum acetateand acetaldehyde levels as compared to control. Anti-hangover preparations enhanced acetaldehydeand acetate metabolism.Conclusion: These fi ndings indicate that anti-hangover preparations may exert benefi cial role inthe treatment of alcohol hangover without any toxicity. Therefore, the content of acetaldehyde wasdecreasing and increasing through repeating 8 hours within 24 hours.

Introduction. Monos Group, Drug Research Institute is starting to investigate of Ellipin preparationfrom the mid-1990s, Ellipin has anti cancer activity in liver and several studies were investigated withscientists from Japan and China. Especially Hayashi K., Khurelbaatar L and Ambaga M were determinedanti-cancer action of the preparation and they were explained of mechanism of action, which apoptosisis seduced by influence of unsaturated fatty acids in tumor cells. However, changes of fatty acidscomposition at production stage were did not study yet. Therefore, we studied that composition of fattyacids in different term of production stage and compared of Ellipin dense substance.Materials and Methods. Samples of study were collected from production stage of “Ellipin” series130304, which was tacked in 48th hour, 120th hour of production. Each sample was dried at freezedryer “Labconco freezone12L” in Drug Research Institute. Total lipids of sample were extracted withchloroform: methanol (2: 1 v/v) according to Folch et al. Fatty acid methyl esters were analyzed usingAgilent Packard Gas Chromatograph (GC) (Model HP-6890 Agilent Packard) with mass-spectrumdetector (Model HP MSD 5973N) of Buryat State University, in Ulan-Ude.Results. Ellipin preparation is derived from bovine liver, and which is based on homogenization of bovineliver for isotonic. In this process, unsaturated fatty acids were extracted in organic solution. We studiedchanges which saturated and unsaturated fatty acids of bovine liver in process of homogenization andconsist of each fatty acid contents of end product. Results have shown that unsaturated fatty acidswere decreased by 0.4-44% till 120th hour of homogenization process. While, there were decreasedby 4-12% in the end product, although, ω-6 fatty acids were increased by 13.1-38.4%. Moreover, 25saturated fatty acids and 12 unsaturated fatty acids were detected in the Ellipin dense substance (endproduct). Hence, 67.5% of total fatty acid was saturated fatty acids, 32.5% was unsaturated fatty acidsin the Ellipin dense substance. Resent results and results of previous studies indicated that Ellipindense substance may contains saturated fatty acids on in average 50.34%, unsaturated fatty acids onin average 49,32%, respectively.Conclusion. Proportion of saturated and unsaturated fatty acids in Ellipin production was about 2:1.Saturated fatty acids and unsaturated fatty acids were found 25 and 12, respectively. Saturated fattyacids were gradually decreased and unsaturated fatty acids were slowly increased in production period,which from 48th hour of production-conveyer till end product. Moreover, content of ω-3-6-9 fatty acidswas consist 83,9-87,5% of total unsaturated fatty acid.

BACKGROUND. UNIFACE 4.0 program has started implementing of UNIFACE 4.0 program for training since 2004 at MNUMS.
In 2008, registration and information of the six branch schools, MNUMS had been transformed into electronic forms. Since 2010, the electronic form and an integrated information environment has been reached all schools equally.
The business Plan of MNUMS is to become “Open School” under the strategic goal, and UNIMIS is being introduced and implementing by the Presidential ordinance A/55, on May 06, 2015.
OBJECTIVE. To analyze the implementation of the university management information system and determine future trends and approaches
RESULTS. In the survey, 7.89% of the subjects were the first group (teachers) responded that it was not appropriate to continue using UNIMIS for training, were below the average, 39.47% of the teachers responded that it was appropriate in some ways and 52.68% said that they would be better useful than average. 15.76% of the subjects were the second group (students) surveyed were moderately unsuitable, 43.15% responded that they were some appropriately, and 41.08% said that they were moderate or higher useful for them. To fulfill consistently the development of UNIMIS in the near future is required to enhance the training specific characteristics and the period, which is the foundation for further application of this program. Over 90% of the teachers who in the study answered that they only used the grades putting into the UNIMIS, the remaining percentages were asked for using students’ self-study and taking a survey. There are many modules in the UNIMIS program, but they are mostly used for students’ grades in it. For teachers, it may be due to a lack knowledge of about UNIMIS.The foundation for further application of this program is required to fulfill and develop UNIMIS permanently with the training specific characteristics and the period.
CONCLUSION. In UNIMIS, there are many issues; inadequate for registration and information (data), incomplete of system usage and applications, not well educated, unsuffiency and a lack of technical and technological safety.

BackgroundPreliminary clinical studies indicate that liver extract may be helpful in treating hepatic dysfunction. In addition, liver extract seems to work synergistically with interferon in treating hepatitis C and other viral infections. Laboratory studies indicate that liver extract may have some effects that could be useful in treating certain forms of cancer, such as ability to direct migration of metastasizing cells and inhibition of DNA, RNA and protein formation. More research is needed in these areas to determine liver hydrolysate’s properties.Materials and MethodsSeveral biochemical methods were used for determination of chemical compounds in liver extracts: Total protein and nitrogen content was determined by Kjeldahl method; mineral contents – atomic absorption spectrophotometer; Heme iron content – spectrophotometer; Water soluble vitamins - HPLC method. The pharmacological activities of bovine liver were tested by several pharmacological methods: Acute toxicity – LD50 /Prozorovskii 1978/; Acute hepatitis – Carbon tetrachloride (CCl4) induced liver damage in rats /Skakun et al, 1984/; Biochemical parameters in blood serum – Automatic biochemical analyzer.ResultThe values obtained in determination of the biochemical analysis show that 100 g consumption of studied liver hydrolysate can provide 4.3, 2.1 and 0.3 mg vitamin B1, B3 and B9 respectively. Therefore, present data reveal that liver hydrolysate is a good source of most of the analyzed minerals. The liver hydrolysate contains 56.4% total protein and 4.33% amino nutrient.Conclusions:1. From the results of pharmacological study that involves CCl4 induced acute toxic hepatitis, liver hydrolysate has hepatoprotective effect by protecting the liver cells from injury, improving the regeneration process and by correcting metabolic functions of the liver.2. When tested, hydrolysate’s pharmacological parameters can be analyzed reliably with several liver damage experimental designs, further improvements or the use of new designs such as anemia is needed in further pharmacological study.
