  • This experiment was conducted to investigate the effects of molasses and $Phellinus$ $linteus$ meal supplementation on the quality of Korean herbal medicine silage. Herbal medicine meal silages were produced by the addition of 0, 15, and 30% of $Phellinus$ $linteus$ meal and 0, 1, and 2% of molasses ($3{\times}3$ factorial design) and stored for 40 days at room temperature. There were three replicates per treatment. Its quality such as chemical composition, pH, organic acids, the number of microorganisms and $in$ $vitro$ dry matter disappearance were determined. As the $Phellinus$ $linteus$ meal level increased, crude protein and crude fat contents increased significantly, but the acid detergent fiber (ADF) content decreased significantly. As the addition of $Phellinus$ $linteus$ meal decreased, and molasses increased, pH tended to decrease, but the lactic acid content trended to increase. The acetic acid content was lower in a higher level (30%) of $Phellinus$ $linteus$ meal, and higher in a higher level (2%) of molasses. As the $Phellinus$ $linteus$ meal level increased, the butyric acid content decreased, and butyric acid of molasses treatment was higher than that of non-supplemented control. Molasses increased the number of Lactobacillus, but decreased the number of fungi in silage. A lower level of $Phellinus$ $linteus$ meal increased the number of Lactobacillus, but decreased the number of fungi. $in$ $vitro$ dry matter disappearance tended to increase by the addition of $Phellinus$ $linteus$ meal and molasses. It is concluded that the addition of molasses and $Phellinus$ $linteus$ to herbal medicine meal silage could enhance its nutritional quality. It is considered that proper levels of molasses and $Phellinus$ $linteus$ meal in herbal medicine meal silage were 2 % and 15% respectively.

  • In our previous study, it was reported that an herbal mixture, SH21B, inhibits fat accumulation and adipogenesis both in vitro and in vivo models of obesity. SH21B is a mixture composed of seven herbs: Scutellaria baicalensis Georgi, Prunus armeniaca Maxim, Ephedra sinica Stapf, Acorus gramineus Soland, Typha orientalis Presl, Polygala tenuifolia Willd, and Nelumbo nucifera Gaertner (Ratio 3:3:3:3:3:2:2). The aim of this study was to investigate the detailed molecular mechanisms of the effects of SH21B on various regulators of the adipogenesis pathway. During the adipogenesis of 3T3-L1 cells, SH21B significantly decreased the expression levels of central transcription factors of adipogenesis, such as peroxisome proliferator-activated receptor (PPAR)$\gamma$ and CCAAT/enhancer binding protein (C/EBP)$\alpha$. To elucidate the detailed molecular mechanism of the anti-adipogenic effects of SH21B, we examined the expression levels of the various pro-adipogenic or anti-adipogenic regulators of adipogenesis upstream of $PPAR{\gamma}$ and C/$EBP{\alpha}$. The mRNA levels of Krox20 and Kruppel-like factor (KLF) 15, which are pro-adipogenic regulators, were significantly down-regulated by SH21B treatment, whereas the mRNA levels of C/$EBP{\gamma}$ and KLF5 were not changed. KLF2 and C/EBP homologous protein (CHOP), which are anti-adipogenic regulators, were significantly up-regulated by SH21B treatment. These results suggest that the molecular mechanism of the anti-adipogenic effect of SH21B involves both the down-regulations of pro-adipogenic regulators, such as Krox20 and KLF15, and the up-regulations of anti-adipogenic regulators, such as KLF2 and CHOP, which results in the suppression of central transcription factors of adipogenesis including $PPAR{\gamma}$ and C/$EBP{\alpha}$.

  • Green tea, a leaf of the plant Camellia sinensis, is one of the most consumed traditional oriental beverages. Green tea has been considered a medicine and a healthful beverage since ancient times, but recently it has received a great deal of attention because of its antioxidants like polyphenols. Moreover, green tea contains amino acids, carbohydrates, proteins, chlorophyll, volatile compounds, minerals, and phytochemical components that are essential or helpful to human health. Depending on the manufacturing process, green teas are classified into several types. Among these, powdered green tea can be effective in the absorption of ingredients compare with other types of green tea since we take the beverage with powder itself. In this paper, the contents of general ingredients (moisture, proteins, fat, carbohydrates, and ash), minerals (Fe, Mg, Ca, Na, K, and P), hunter color values, and alcohol insoluble substance were determined in total of six powdered green teas commercialized in Korea and Japan.

  • This study was carried out to determine the proximate composition, amino acids and fatty acids contents and changes of physicochemical characteristics of each oil extracted from Spanish and Virginia type peanuts grown in Korea roasted at 110, 120, 130 and 14$0^{\circ}C$ for 2 minutes. 1. The moisture contents of raw Spanish and Virginia type peanuts were 6.5~6.8% respectively. The crude ash and reduced sugar contents of raw Spanish and Virginia type peanuts were 2.3% and 16.5% and the crude protein content was 27.0% in Spanish type peanuts and was aproximately 1% higher than in Virginia type peanut. The protein content was 25.7%~26.7% in Virginia type peanut roasted at 110, 120, 130 and 14$0^{\circ}C$. The crude fat content of Virginia type peanut was 46.0% which was aproximately 1% higher than that of Spanish type. But four kinds of oils content were 51.3%~51.8% in Spanish type peanut roasted at 110, 120, 130 and 14$0^{\circ}C$, which was about 2% higher than those of Virginia type. 2. Amino acids existed in peanut were glutamie acid, arginine, aspartic acid, leucine, glycine, phenylalanine, proline-lysine, tyrosine, valine and isoleucine, etc mainly. But methionine and threonine contents were very low. The content of glutamic acid was the highest in 71.6-81.7mg among amino acids. Glutamic acid content of Virginia type peanut was about 12% higher than that of Spanish type peanut. Total amino acid content was 441.8mg/g in Virginia type peanut and that was 16% higher than that of Spanish type peanut. The lysine content of Spanish and Virginia type peanuts roasted at 14$0^{\circ}C$ were 24% and 13%, these were lower than those of peanuts roasted at 11$0^{\circ}C$. 3. Main fatty acids of raw Spanish and Virginia type peanut oils were oleic(40.99-46.58%), linoleic(33.21-38.82%) and palmitic acid(9.72-11.58). Linoleic acid content of raw Virginia type peanuts was 5.6% higher than that of raw Spanish type peanut. And the oleic acid content of Spanish and Virginia type peanuts roasted at 11$0^{\circ}C$, 12$0^{\circ}C$, 13$0^{\circ}C$ and 14$0^{\circ}C$ was 50-53% and 41-43% respectively. Linoleic acid content of Spanish and Virginia type peanuts roasted at same temperatures as the former was about 28-31% and 37-38% respectively. That linoleic acid content of roasted peanuts was lower than that of raw peanuts. Linoleic acid content of raw and roasted Virginia type peanut, were higher than that of Spanish type peanuts. 4. Acid value and peroxide value of oils extracted from roasted Spanish and Virginia type peanuts were much higher than those of oils extracted from raw peanuts. The maximum AVs of oils extracted from Spanish and Virginia type roasted peanuts were samples roasted at 12$0^{\circ}C$and those AVs were 0.50 and 0.63 respectively. And the maximum POVs of oils extracted from Spanish and Virginia type roasted peanuts were samples roasted at 12$0^{\circ}C$ also and those POVs were 26.8 and 32.8 meq/kg. oil respectively. Acid value and peroxide value of oils extracted from roasted peanuts were increased with increasing the roasting temperatures from 11$0^{\circ}C$ to 12$0^{\circ}C$, then decreased, while TBA values were increased continuously with increasing the roasting temperatures.

  • The aim of the present study was to determine the effects of a low-energy finisher diet on feed and growth efficiencies and carcass traits of ‘high’-market weight (MW) finishing pigs and thereby to extrapolate optimal dietary energy level for the high-MW swine. A total of 160 (Yorkshire × Landrace) × Duroc-crossbred finishing gilts and barrows weighing approximately 90 kg were fed a low-energy (3,200 kcal DE/kg) diet (LE) or control (3,400 kcal) diet (CON) ad libitum in 16 pens up to 135- and 125-kg live weights, respectively, at which the animals were slaughtered and their carcasses were analyzed [2 (sex) × 2 (diet) factorial experimental design]. Average daily gain, average daily feed intake and feed efficiency did not differ between the two sex or diet groups. Backfat thickness was less (P<0.05) in LE (22.4 mm) than in CON group (24.3 mm) in gilts, but not in barrows (24.4 ± 0.4 mm). The percentage of C- & D-grade carcasses was over 90% because of the ‘over-weight’ problem in gilts, whereas in barrows, percentages of A plus B grades and C plus D grades were 79% and 21%, respectively. The yield percentage of each trimmed primal cut per total trimmed cuts (w/w) did not differ between the two sex or diet groups. Physicochemical characteristics of longissimus muscle including color (lightness and redness), pH, drip loss and chemical composition, which overally were within the range of normal carcass, also did not differ between the two sex or diet groups. In conclusion, both LE and CON are judged to be adequate for the high-MW swine during the latter finishing period. If fat deposition of a given herd of high-MW pigs needs to be suppressed by a dietary treatment, the energy content of the diet will have to be reduced to a level lower than 3,200 kcal DE/kg.

  • This experiment was performed to investigate the effect of the frequency of meals on the metatolism and the body composition of rats when equal amount of purified diet was ingested. Thirty approximately days old rats weighing 290 g and thirty-two about 40 days old rats weighing 180 g were employed for the period of 34 days. Rats fed ad libitum (10 to 15 meals per day) and two-meal per day were pair-fed and equal amount of diet was fed to each rat in pair. The experimental results obtained are summarized as follows: 1. Frequency of meal did not exert any effect on the body weight gain. However, rats fed two-meal per· day gained significantly (p <0.005) more fat and energy than ad libitum group. The rate of gain of protein in ad libitum group was higher than that of two-meal group. No difference was observed for the mineral deposition of rat body. 2. From the preperation of rat liver it was found that the activity of glucose-6-phosphate dehydrogenase was much higher for the rats fed two-meals per day than those fed ad libitum. Therefore, it is suggested that the metabolic pathway of carbohydrate for two-meal group has been shifted from glycolysis to Hexose Monophosphate Shunt and produced more NADPH which would be the essential cofactor of fatty acids synthesis. 3. The rate of excretion of urinary nitrogen for two-meal group was significantly (p<0.005) higher than that of ad libitum group. It is apparent that considerable amount of over-loaded amino acids by feeding two-big-meal daily· could not be used for the protein biosynthesis all at once and excreted following deamination through urine. The residual carbon chain could be served as a precursor of fatty acids synthesis. 4. The heat production rate of rats fed two-meal group was significantly (p<0.005) lower than that of ad libitum group. It seems possible that the activity of thyroid gland (and consequently BMR) can be depressed by the frequency of meal.

  • Purpose: Renal stones are common and typically arise within the collecting system. The renal sinus are contains the collection system, the renal vessels, lymphatcs, fat, and fibrous tissue. Because of the compression of all the large echoes in signal processing, the echo from the renal stone generally cannot be distinguished from large echoes emanating from normal structures of the renal sinus. Use of ultrasonography has been difficult for detecting small renal stone without posterior shadowing and chemical composition of stone. The aim of study was measuring for posterior acoustic shadowing to a stone for various scan parameter and it examines a help in renal stone diagnosis. Material & Methods: The stone was place on sponge examined in a water bath with a 3.5MHz or 7.5MHz transducer(LOGIQ 400, USA). First, tested a variety of gain. Second, tested a variety of dynamic range. Third, tested a variety of focal zone. Fourth, measuring of the echo level for low and high frequency for depth. Results: 1) Average echo level was 98 for low total gain(10 dB) and was 142 for high total gain(40 dB). Posterior acoustic shadowing of renal stone was clear for low gain. 2) Average echo level was 129 for low dynamic range(42 dB) and was 101 for high dynamic range(72 dB). Posterior acoustic shadowing of renal stone was clear for high dynamic range. 3) When stone is in focal zone of transducer, definite posterior acoustic shadow is identified. 4) Stone was clear appeared for high frequency(7.5 MHz) than low frequency(3.5 MHz) and it is not distorted. Conclusion: The demonstration of an posterior acoustic shadow of renal stone dependents on several technical factors such as gain, dynamic range, focus, and frequency. This various factors are a help in renal stone diagnosis.

  • Aiming at the total 200 pregnant women including 150 ones registered with the Health Center of Chung Ku District and 50 ones registered with the Health Center of Mapo District, we have conducted a research study of the socio-medical characteristics, maternal child health, and the status of nutritional intake which has utilized the application of convenient method for the study of nutritional status, during the period of April 20 to May 25, 1983. And we have obtained the following conclusions: 1. Regarding age distribution, the pregnant women aged from 26 to 30 were most numerous, which was 54.0%. The percentage of women who experienced the first pregnancy was 12.0% and the percentage of those who experienced the second pregnancy was 37.0%, which was the highest. Regarding the weeks of pregnancy of the pregnant women, the first trimesterr was 11.5%, the second trimester 30.0%, and the third trimester 58.6%. 2. Regarding academic achievements, the pregnant women who graduated from middle schools reached 43.5%, which was the highest percentage. Regarding economic status, the pregnant women who owned their own houses were only 21.0%. And the pregnant women whose monthly income was from 300,000 won to 400,000 won were 40%, which was the most numerous. 5. The women above 15 years old who experienced the first menstruation were 84.0%. And those who experienced abortion were totally 54.4%. and 35.5% among those women experienced artificial abortion. 4. 70.5% of the pregnant women said that their health condition was excellent, 24.5% felt subjective complaints, and 5.0% specially received medical consultation for their diseases. 5. 82.0% received prenatal care, but 60.5% regularly received prenatal care. 68.0% received the education for nutrition and only 19.5% regularly received the education for nutrition. 6. Regarding the family composition, the families consisting of two generations were 47.0%, which was the most numerous. 97.5% of the preparation for meals was conducted by housewives. They said that they did not lack time for meal preparation. 7. 94.9% of the pregnant women said that they had eaten as in ordinary times during their pregnancy. 25.5% said that there were tabooed foods. Tabooed foods are chiefly pork, chicken, milk, and eggs. 68.0% don't drink milk during pregnancy, 32.5% take the intake of vitamins, and 20.5% take iron supplement. 8. The average amounts of the intake of protein, fat, and carbohydrate of a pregnant women are 49.3gm, 29.4gm, and 205.1gm respectively, which showed the phenomenon in which the amount of the intake of nutrition increased as the weeks of pregnancy increased. The average amount of the intake of salt was 14.2gm. 9. Regarding the hemoglobin value of all pregnant women, those whose hemoglobin value was less than 11.0gm were 66.5%, those whose hemoglobin value was 11 to 12 gm were 16.5%. and those whose hemoglobin value was above 12gm were 17.0%. The pregnant women whose hemoglobin value was less than 11.0gm in the first trimester of pregnancy, in the second trimester, and in the trimester were 81.8%, 62.8%, and 64.9% respectively. This shows that the phenomenon of anemia increased as the weeks of pregnancy increased 10. Regarding physical development of a pregnant woman during prenatal period, the height and weight were $156.7cm{\pm}14.1$ and $51.1kg{\pm}58$ respectively. When the standard increase of a prenatal weigt gain is set as 100%, the women over the range of 100% were 28.0% and the women under the range of 80% were 37.0%.

  • Food irradiation has recently become one of the most successful techniques to preserve food with increased shelf life. This study aims to analyze hydrocarbons in almonds (Prunus amygosalus L.) and peanuts (Arachis hypogaea) induced by electron beam irradiation. The samples were irradiated at 0, 1, 3, 5 and 10 kGy by e-beam and using florisil column chromatography fat, and content was extracted. The induced hydrocarbons were identified using gas chromatography-mass spectrometry (GC/MS). The major hydrocarbons in both irradiated samples were 1,7-hexadecadiene ($C_{16:2}$) and 8-heptadecene ($C_{17:1}$) from oleic acid, 1,7,10-hexadecatriene ($C_{16:3}$) and 6,9-heptadecadiene ($C_{17:2}$) from linoleic acid and 1-tetradecene ($C_{14:1}$) and pentadecane ($C_{15:0}$) from palmitic acid. Concentrations of the hydrocarbons produced by e-beam were found to be depended upon the composition of fatty acid in both almonds and peanuts. The $C_{n-2}$ compound was found to be higher than $C_{n-1}$ compound in oleic acid and palmitic acid, while in case of linoleic acid, $C_{n-1}$compound was higher than $C_{n-2}$ compound. The radiation induced hydrocarbons were detected only in irradiated samples, with 1 kGy or above, and not in the non-irradiated ones. The production of 1,7-hexadecadiene ($C_{16:2}$), 8-heptadecene ($C_{17:1}$), 1,7,10-hexadecatriene ($C_{16:3}$) and 6,9-heptadecadiene ($C_{17:2}$), in high concentration gave enough information to suggest that these may be the possible marker compounds of electron beam irradiation in almonds and peanuts.

  • This study investigated the effect of mulberry fruit extract(MFE) on antioxidant and anti-inflammatory activities of middle aged women with rheumatoid factor (RF). Thirty two middle-aged subjects were divided into two groups which were normal middle-aged group (NMG) and abnormal middle-aged group whose serum RF level were > 10 u/mL (AMG). All groups had consumed MFE (100 mL/day) for 4 weeks. Anthropometric measurements, serum inflammatory factors, serum oxidative stress markers analyses were performed at baseline and then at 4 weeks following the study. There were no significant differences in anthropometric measurements, including BMI, WHR and body fat composition between two groups. But after 4 weeks MFE consumption, serum levels of C-reactive protein (CRP), ferric-reducing ability of plasma (FRAP), serum TNF-${\alpha}$, IL-2, IL-4 had significantly decreased (p<0.05) in AMG. These findings suggested that the MFE consumption as food may be protective against oxidation and inflammation like RA.
