Immunoregulative Action of Ethyl Alcohol Fraction of Cervus nippon
The Korean Journal of Food And Nutrition, volume 14, issue 2, 2001, Pages 99~105
Immunoregulative action of 70% ethyl alcohol fraction of Cervus nippon was investigated in vitro. The fraction enhanced the proliferation of thymocytes and the population of CD4
-/ single-positive cells in thymocytes. CN-E enhanced [Ca
i/, the production of TNF-
, and phagocytosis in peritoneal macrophages. The fraction did not induce the proliferation of splenocytes and DNA fragmentation in thymocytes. These results indicate that 70% ethyl alcohol fraction of Cervus nippon regulates immunological action by stimulating murine thymocytes and macrophages.
The Effect of Regular Exercise on Nutritional Intakes and Energy Balance of College Women
The Korean Journal of Food And Nutrition, volume 14, issue 2, 2001, Pages 106~112
The purpose of this study was to investigate to the effect of regular exercise on nutrients intakes and energy balance related to food habit and nutrient knowledge of college women. This study was conducted from May to June in 2000. One hundred and forty female students made their three day dietary records by 24-hr recall method and one day activity record. The questionaires were designed to fine out food habit and nutrition knowledge status. The height. weight and blood pressure were measured and also body fat mass and lean body mass measurements were performed. The results obtained are summerized as follows. Average height and weight of E(exercise) group were found to be increased than those of NE(non-exercise) group. The percent of body fat and body fat mass(kg) in E group were slightly lower than those of NE group. Calorie intake of NE group was 1,664kca1 per day. This was composed of carbohydrate 60%kcal. protein 14%local and fat 24%local. Calorie, calcium, iron, vitamin A, vitamin B
and niacin intakes of NE group were lower than those of RDA and calorie intake of E group was 2.313kca1 per day. This was composed of carbohydrate 54%, protein 13% and fat 31%. Other nutrients such as iron, vitamin A, niacin and vitamin C were lower than those of RDA. Daily energy expenditure and physical activity of E group were 2,397.6
36.5kcal, respectively and it was higher than those of NE group.
The Effect of Regular Exercise on Body Fat Contents and Blood Lipid Compositon of College Women
The Korean Journal of Food And Nutrition, volume 14, issue 2, 2001, Pages 113~119
The purpose of this study was to compare to the effects of regular exercise on body fat contents and plasma lipid composition of college women. This study was conducted from May to August in 2000. The subjects selected for the experiment were composed sixty three female college students. The basal anthropometric measurements were performed. The levels of total cholesterol, HDL-cholesterol, triglyceride and fatty acid composition of plasma were determined. And plasma glucose concentrations was also assayed. The results obtained are summerized as follows : Average height and weight of E(exercise) group were found to be slightly higher than NE(non exercise) group. The percent of body fat and body fat mass (kg) in E group was slightly lowered than that of NE group. There was decreased on the levels of plasma total cholesterol, triglyceride by regular exercise. HDL-cholesterol level was not significantly different between two groups, but LDL-cholesterol level in E group was significantly lowered than that of NE group. Therefore, plasma total cholesterol and LDL cholesterol levels was significantly decreased by regular exercise.
Inhibitory Effects of the Solvent Fractions from Persimmon Leaves on Xanthine Oxidise Activity
The Korean Journal of Food And Nutrition, volume 14, issue 2, 2001, Pages 120~125
The inhibitory effects of xanthine oxidase by the methanol extract and the solvent fractions obtained from persimmon leaves were investigated. The inhibition ratio of xanthine oxidase was 78% by addition of 2.0mg/ml of the methanol extract. Among the solvent fractions, the ethylacetate fraction showed the strongest inhibitory effect against the xanthine oxidase, followed by the hexane fraction. The effect increased with addition of the ethylacetate fraction. At a concentration of 2.0mg/ml of the ethylacetate fraction, 65% of the enzyme activity decreased within 1.0 min of incubation with xanthine oxidase. But the activity of xanthine oxidise did not decrease significantly by the length of the incubation time.
Microbiological, PH and Sensory Evaluations of Refrigerated Pork Loins Treated with Lactococcus lactis ATCC l1454
The Korean Journal of Food And Nutrition, volume 14, issue 2, 2001, Pages 126~131
Microbiological, pH and sensory evaluations of pork loins treated with lactic acid cultures (Lactococcus lactis subsp. lactis ATCC 11454 grown in 10% milk solids) during storage at 4
were assessed. Pork loins were immersed in solutions containing 3.96 log units, 4.10 log units, or 4.23 log units of individual lactic acid cultures for 2 min. Pork loins treated with lactic acid cultures had a inhibitory effect (P<0.05) on the growth of aerobic palate counts during storage of 3 days at 4
. Pork loins treated with lactic acid cultures during storage of 3 days at 4
significantly (P<0.05) decreased pH values compared to those of controls. Sensory evaluations for odor and appearance of pork loins treated with lactic acid cultures during storage of 9 days at 4
were a "liked less" to "typical" category compared to those of controls.
A Study on Contents of Trace Metal of the Agricultural Products around Mines Located in Chollanam-Do
The Korean Journal of Food And Nutrition, volume 14, issue 2, 2001, Pages 132~137
To know a degree of pollution in agricultural products cultivated around 4 unworked mines located in Chollanam-Do, we investigated a concentration of trace metal to provide the basic data for its residual limits. 28 samples of seven kinds of agricultural products (lettuce, onion. potato, radish, pepper. pumpkin, bean) collected from 4 unworked mines located in Chollanam-Do in 1999 were analyzed by Mercury Analyzer for mercury and Atomic Absorption spectrophotometer for Pb, As, Cd. Cu, Mn, and Zn. Hg contents were detected N.D. ∼trace level (0.01 ppm and less) and As contents were detected N.D. ∼ 0.038 ppm but most of samples were not detected. Cd contents were detected N.D∼0.101 ppm. The results of Hg, As, Pb and Cd content showed that for all the 7 species of agricultural products studied, none have accumulated levels dangerous enough to pose health problems. The average contents of Cu were 4.356∼10.624 rpm in bean. the Mn were 4.332∼24.385 ppm in lettuce and the Zn were 4.072 ∼ 20.715 ppm in bean, respectively.
Effect of Fed Chlorella on the Change of Lipid Components and Enzyme Activity in Serum of Rat by Lead Exposure
The Korean Journal of Food And Nutrition, volume 14, issue 2, 2001, Pages 138~144
This study was performed to investigate the influence of Chlorella which effected the change of Pb contents, enzyme activity and lipid compounds on the rats fed the beverage involved Pb and the different contented Chlorella added-diets for 18weeks. The rat's weight of 200ppm Pb group was decreased 6.04% and the cause of that was Pb intake. But the rat's weight of Chlorella added-diets +200ppm Pb group was increased 4.02% (p<0.01). When feeding the different(0%, 2%, 5%, 10% ) Chlorella added-diets with the Pb contented beverage to the rats, we could know that the Pb contents accumulated on tissue were decreased to 20.70(0%), 12.88(2%), 14.83 (5%) and 19.56(10%), compared with the quantity of Pb taken in. Total-cholesterol, triglyceride, glucose content and AST, ALT, ALP, LDH enzyme activity in serum were the highest on 200ppm Pb group and those were decreased by the order of different(2%∼5% >10%) Chlorella contents + 200ppmPb group. A significance was recognized on the level of 1%. Therefore, when rats were exposed to Pb, it was thought that the amount of Chlorella intake was adequate on content 2∼5% for reducing the lead toxicity.
Dongchimi Fermentation for Nangmyeon - Changes of Chemical Property during Fermentation -
The Korean Journal of Food And Nutrition, volume 14, issue 2, 2001, Pages 145~149
One percent starch-added Dongchimi, and Dongchimi which 1% starch was not added. each using, 70% radish cut in 2cm size were fermented at 4
for 30 days. HPLC and TLC analyses showed that the no starch-added Dongchimi had glucose, fructose, sucrose. The starch-added Dongchimi produced, mal-tose. maitotriose and maltotetraose by the hydrolysis reaction of amalyse. And the sugar contents were reduced in the process of fermentation. No starch-added Dongchimi showed 361
g/ml of reducing sugar, 0.012 unit /ml of amylase activity, 3.82 of pH, 3.0 of acidity. The 1% starch-added Dongchimi showed 329
g/ml of reducing sugar, 0.04 unit/ml of amylase acidity, 3.8 of pH. 3.15 of acidity.
Effect of Improve Obesity with Sprout Raw Grains and Vegetables
The Korean Journal of Food And Nutrition, volume 14, issue 2, 2001, Pages 150~160
This study was carried out to investigate the effect of weight loss and the change of serum lipids composition for normal and obese women after sprout raw grains and vegetables diet intake. Diet were given to the subjects which were composed of 11 normal women and 7 obese women for 4 weeks. After diet intake, 4.6% in normal group and 3.5% in obese group were shown weight loss. And the both groups of normal and obese women showed a significant reduction in the thickness of subcutaneous fat and the body girth. Particularly, the waist measure was shown to be remarkably reduced in the normal group (p< 0.0001) and to be reduced in the obese group (p<0.017) significantly. After diet intake. the levels of total cholesterol and triglycerides were reduced in both groups significantly. And in the obese women, HDL-cholesterol level increased 5.7%. As those results, it could be seen that weight and the thickness of subcutaneous fat were reduced and the component of blood serum were improved after diet intake for 4 weeks. Specially, abdomen, waist measures and hip girth were reduced remarkably, so it is considered that the diet is more effective in the diet therapy of obese women with upper obese status.
Studies on the Processing of Yeast Extract by Waste Brewery Yeast
The Korean Journal of Food And Nutrition, volume 14, issue 2, 2001, Pages 161~166
The optimum condition for production of yeast extract by autolysis and enzymatic method were studied with waste brewers\` yeast. The major components of brewer\`s yeast in proximate compositions were carbohydrate(46.0%) and protein(41.7%). There was a little appreciable difference in the promaximate composition of waste brewers\` and bakery yeast. The major minerals were identified as K, P, Mg and Ca, and their contents were about 1,659.7%, 1,197.4mg%, 210.4mg% and 105.6mg%, respectively. The major vitamins were identified as vitamin C and vitamin B group, and their contents were about 7.9IU/100g and 4.2IU/100g, respectively. The optimum yeast concentration in the reaction suspension was 10% (w/v) waste brewer\`s yeast slurry. The protein content in brewer\`s yeast extract was increased with addition of NaCl as plasmolyzers. However, the plasmolyzer effect of ethanol a little showed as the concentration increasd from 3% ∼7%. The 5\`-nucleotides(5\`-GMP and 5\`-IMP) content in brewer\`s yeast extract was increased with addition of glucanase. The total content of 5\`-nucleotides (5\`-GMP and 5\`-IMP) increased by 160% than those by the autolysis of waste brewer\`s and bakery yeast.
The Components of the Fermented Soy Sauce from Gorosoe and Bamboos SaP
The Korean Journal of Food And Nutrition, volume 14, issue 2, 2001, Pages 167~174
Soy sauce was prepared with the addition of Gorosoe and bamboos sap instead of tap water to make ordinary soy sauce, respectively. The changes of such compounds during fermentation as minerals, free sugars, organic acids and free amino acids were analyzed. Total mineral contents in the 90 days fermented soy sauce from Gorosoe and bamboos sap were increased by 2.0 and 4.4 times as compared with those of control samples, respectively. Especially the increase of calcium, potassium and magnesium in soy sauce of sapes were derived from those of saps. The sugars were found to be only glucose and galactose in control samples, but they were detected not only above sugar but also fructose and sucrose in soy sauce of saps. Butyric acid in detected organic acid were dominant in all stray sauce samples. In the free amino acid composition of control samples, leucine, phenylalanine, isoleucine, lysine and glutamic acid were abundant amino acids. Amino acid such as isoleucine, leucine and phenylalanine were decreased, the rest 11 kinds of amino acids containing phosphoserine were increased during the fermentation of control samples. Increasing and decreasing patterns of free amino acids during fermentation of sap soy sauce were similar to control samples. Total nitrogen, amino acid nitrogen and ammonia nitrogen were increased during their fermentation.
