In order to conduct research on oil originated in Mongolia for further application of petroleum not only as fuel but also as raw material for organic synthesis, we need to study the physical, chemical characteristics and individual, group hydrocarbon's compositions of main petroleum fractions. A number of studies and surveys on the physical and chemical characteristics, group hydrocarbon's composition of petroleum deposits in Zuun-Bayan, Sukhaibulag, Tsagaan Elst, Tamsagbulag have been carried out earlier through n-g-M, aniline point and dispersimetric methods successfully. Yet a detailed chromatographical and NMR spectroscopic study for the individual hydrocarbon's composition of Tamsagbulag oil main fractions has not been conducted. In the present study the results of GC analyses of gasoline fractions of wells 19-3, 19-13 and 19-10, Tamsagbulag (Eastern Mongolia) were presence. The gasoline fractions of given wells were characterized by the high concentration of paraffins and presence of trace amount of olefins. There were identified 69 paraffins, 45 naphthenes, 41 aromatics and 3 olefins in total 158 individual hydrocarbons from each samples of gasoline fraction. The first attempts to classify Tamsagbulag oil under the individual hydrocarbon's composition data were successfully conducted and the supposition of a genetic classification of given oil as "sapropelic" type was made.

The effects of sardine oil(high in eicosapentaenoic acid : EPA) and tuna oil(high in docosahexaenoic acid : DHA, also high in EPA) on fatty acid composition of brain and learning ability were evaluated in male weanling Sprague-Dawley rats and compared with the effects of corn oil and beef tallow. Animals assigned by randomized block design to one of the four experimental diet groups containing dietary lipid at 15%(w/w) level were given ad libitum for 7 weeks. Food intake and body weight gain of the fish oil groups were significantly lower than those of the corn oil and beef tallow groups. However, brain weights of the groups were not significantly different. In the brain fatty acid composition, the corn oil group showed high concentrations of n-6 fatty acids, the fish oil groups of n-3 fatty acids, and the beef tallow group of saturated fatty acids. Brain EPA and DHA contents of the fish oil groups showed significantly higher than the other groups while the brain ratio of saturated/monounsaturated/polyunsaturated fatty acid was controlled in a narrow range. In a maze test, the fish oil groups appeared to arrive at the goal faster than the corn oil and beef tallow groups. It explained that EPA in diets might efficiently convert to DHA resulting in DHA accumulation in brain tissue and might increase the learning performance as DHA did.

Objective: The community has implemented a variety of exercise programs for the elderly population. However, studies comparing changes in the cardiovascular system through body composition and blood analysis after applying aqua aerobic exercise are insufficient. The purpose of this study was to investigate the effect of a 12 weeks aqua exercise on body composition and cardiovascular index in elderly women. Design: Non-equivalence pre-post design. Methods: Thirty elderly women were assigned to aquarobic group(n=15) and control group(n=15). The aquarobic exercise was 60 minutes per every session, 2times per week, for 12weeks. Weight, skeletal muscle mass, body fat percentage, total cholesterol, triglyceride, HDL cholesterol, and LDL cholesterol were measured before and after the exercise program. Paired and independent t-tests were performed using SPSS program. Results: The result showed was weight(p<0.05), body fat percentage(p<0.05), total cholesterol(p<0.05), triglyceride(p<0.05), HDL cholesterol(p<0.05), and LDL cholesterol(p<0.05) were significantly decreased and skeletal muscle mass(p>0.05) was not significantly increased after aquatic exercise program. Conclusions: According to the study result, aqua exercise program made a positive effect in the improvement of obesity and cardiovascular function in elderly women. Therefore, we suggest that you actively consider implementing the Aquarobic exercise program when operating the community health promotion program in the future. In addition, in future studies, comparative studies according to various ages and genders and studies on the effects of aqua aerobic exercise as a community exercise program for chronically illness patients are needed.

This study is to find out the antioxidative effect and serum and liver lipid composition of wild grape juice in vivo. Forty 6-week-old white Sprague Dawley rats were divided into 4 groups such as normal lipid group, normal lipid group with wild grape juice, oxidized lipid (basic diet plus 10% of oxidative lipid) group and oxidized lipid group with wild grape juice, and 2ml juice was provided everyday. After 4 weeks of feeding with experimental diet each groups were examined for the antioxidant enzyme activity in blood and liver microsome and their serum and liver lipid composition. Glutanthione peroxidase activity in blood was significantly higher in oxidized lipid group with wild grape juice than in oxidized lipid group. Glutanthione peroxidase activity showed no difference depending on wild grape juice supplementation. Glutanthione peroxidase activity in liver was significantly higher in the groups with wild grape juice than in the groups supplemented only with oxidized lipid. Glutanthione reductase activity showed no difference depending on the supplementation of wild grape juice. Serum triglyceride level in the group supplemented with oxidized lipid diet and wild grape juice showed similar value to the normal lipid group and the normal lipid group with wild grape juiceoxidized fa6. Liver total lipid in the group supplemented with oxidized lipid and wild grape juice showed similar value to the normal lipid group and the group supplemented with normal lipid and wild grape juice. And it was lower than that of oxidative lipid group without juice. The liver triglyceride level in the group supplemented with normal lipid and wild grape juice was lower than that in the oxidative lipid group, but it was as low as in the group supplemented only with normal lipid.

This study was conducted to investigate the supplementary effects of vitamin C and E to moist pellet on growth and body composition in juvenile olive flounder (Paralichthys olivaceus). Four groups of diet made : moist pellet (MP) diet group was used as the control group where the ratio of raw feed and commercial compound meal is 5:5 $(CP\;30\%,\;CL\;17\%),$ vitamin C added group (VC), vitamin I added group (VE) and vitamin C and I added group (VCE). The supplementary amount of vitamin C and E corresponded to 1000 mg/kg (dry wt.) and 220mg/kg (dry wt.), respectively. Vitamin C was destroyed $50\%$ and vitamin E was destroyed $20\%$ for manufacturing process. After 8 weeks feeding trial, weight gain was $121.9\%$ in MP group, while it ranged from 180.5 to $184.9\%$ in the VC, VE and VCE group. Feed efficiency was $71.\6%$ in MP group, whereas it ranged from 78.7 to $80.6\%$ in the VC, VE and VCE group, weight gain and feed efficiency of fish fed vitamin supplemented diets were significantly higher than control group and no significant difference among the vitamin added groups was observed (p>0.05). There were no significant differences in moisture, crude protein, crude lipid, crude ash, condition factor (CF), hepatosomatic index (HSI), and visceraweight index (VWI) of body composition. Hemoglobin (Hb) was $3.79\%$ in MP group, whereas $4.99\%$ in VC group, $4.55\%$ in VE group and $5.07\%$ in VCE group; Hb was significantly higher in the vitamin added groups than the control group (p<0.05). Vitamin C retention in liver was 18.1, 20.7, 46.6, 54.0 mg/kg in MP, VE, VC and VCE groups, respectively. Vitamin E retention in liver was 25.9, 53.8, 88.2, 124.5 mg/kg in MP, VC, VE and VCE groups, respectively. These results indicate that supplementation of vitamin C and E to moist pellet diet significantly improved growth and feed efficiency of olive flounder, and the mixed addition of vitamin C (1,000 mg/kg dry wt.) and vitamin E (220 mg/kg dry wt.) did not lead to the synergy effect.

This experiment was performed to investigate the effect of different dietary lipids on the risk factors of coronary vascular disease(CVD) in ovariectomized rats. female rats of Sprague-Dawley stram were divided into sham-operated(sham) and ovariectomized(ovx) groups and then each group was divided into a beef fallow group, a soy bean oil group and a fish oil group. After 16 weeks of feeding on experimental diets, animals were sacrificed and blood, liver, kidney and perirenal fat pad were obtained. Food intake and weight gain of fish oil group were significantly lower than other dietary lipid groups. food intake and weight gain tended to be higher in ovx groups than in sham groups. The weight Index(g/100g body weight) of liver and kidney was higher in the fish oil group than the other groups and weight index was lower in ovx groups compared to sham groups. The weight of the perirenal fat pad was the highest in the beef tallow group and the lowest in the fish oil group. The fish oil group showed the lowest total cholesterol(TC) and triglyceride (TG) levels in serum. Serum TG levels were lower in all ovx groups than in sham groups, but serum TC levels were not influenced by ovariectomy. fatty acid composition of serum reflects the recent dietary Intake of fat. Linoleic acid content was tile highest in soy bean oil group and eicosapentaenoic acid(EPA) and docosahexaenoic acid(DHA) contents were the highest in fish oil group. fatty acid composition of adipose tissue, especially EPA and DHA contents in perirenal fat pad, was highest in the fish oil group. Saturated fatty acid(SFA) and monounsaturated fatty acid(MUFA) in serum and adipose tissue did not reflect fatty acid intake. The activities of glucose-6-phosphate dehydrogenase, a lipogenic enzyme, in the blood of the beef tallow and soybean oil groups showed the tendency to be high and that of the fish oil group to be low in ovx. Carnitine acetyltransferase, a lipolytic enzyme, showed the highest activity in the liver of the fish oil group and was least active in the soy bean oil group.
