  • In this study, raw ginseng produced by different methods was puffed, and physicochemical properties were analyzed and compared. Raw ginseng included white ginseng lateral root (WGL), red ginseng lateral root (RGL), red ginseng main root (RGM), and red ginseng main root with 15% (w/w) moisture (RGMM). All samples were puffed at a pressure of 7 kg/cm2. Crude saponin content was increased after puffing compared with that of control ginseng. RGM and RGMM showed significant increases in crude saponin content, from 1.67% and 1.41% to 2.84% and 3.09% (all w/w), respectively. However, the ginsenoside content of WGL was decreased after puffing. Rg3, Rh1, and Rh2 values of red ginseng were increased by puffing compared with those of control red ginseng. The total sugar content of ginseng decreased after puffing. The mineral components of puffed ginseng were similar to those of raw ginseng. Levels of total phenolic compounds and antioxidant activities of ginseng were increased after puffing, and electron-donating ability was greatly increased. The acidic polysaccharide content of ginseng increased slightly and the amino acid content decreased due to the high temperature used during puffing.

  • This study was conduced to ferment high quality wine by using Omija fruit. Dry Omija farmed and dried in the Moonkyung area was used in this study. The Omija was soaked in 10~40 folds of distilled water to extract water-soluble components and the fluid was filtered after soaking for 6 hours at $50^{\circ}C$. Strains of alcoholic yeast were isolated respectively from spoiled Omija extract. Isolated alcoholic yeasts, OM-1 and OM-2, showed a round to ellipsoidal shape and formed white or milky white colonies on a solid YM medium. Two yeasts produced 10.33~11.23% alcohol from Omija extract adjusted to $10^{\circ}Brix$ with sugar. Their abilities to ferment alcohol were higher than those of other yeast strains belonging to Saccharomyces cerevisiae such as KCTC 7296 (standard strain of Korean Biological Resources Center), Makgeolli yeast, or beer yeast. The isolates OM-1 and OM-2 showed similar abilities in alcohol fermentation. However, the wine fermented by OM-2 got a better sensory score especially with color. Growth of OM-2 was significantly accelerated by addition of a 0.1% urea and 0.02% mineral mixture. A vitamin mixture was effective for the growth only when urea was added as well.

  • Recently, an interest in functional foods has been increasing. It was recommended placing a short definition. Therefore, we performed research on the chemical functions and antioxidant ability of broccoli. This research is vital for preparing the most favorable conditions and environment for highly-functional broccoli. Broccoli produced after applying sprouting and light sources were used for research. The chemical properties of the broccoli, including composition, free sugar, citric acid, mineral and vitamin (A, C, E) content, were analyzed. In addition, the ability of broccoli compounds to reduce total phenolic compounds, SOD-liked activity, EDA (electron donating ability), and hydroxyl radicals were inspected. Total analysis relied on the SAS (statistical analysis system). Broccoli sprouts produced through plant factory system's photosynthesis, treated under different light sources, had superior amounts of crude protein, crude fat, and crude ash, compared to normal sprouts under fluorescent light. Is it a facility or does it refer to the inner metabolism of the cell? Broccoli sprouts under red light had superior amounts of glucose, fructose, malic acid, and oxalic acid, while broccoli sprouts under turquoise light had superior amounts of citric acid. Broccoli sprouts under white light had superior amounts of various minerals, such as potassium, magnesium, and sodium. In terms of antioxidant activity, data from the plant factory system shows an increase in EDA antioxidants (1.63 mg/mL, 30.82%). Sprouts applied with turquoise light had superior amounts of hydroxyl radical scavenging (65.62%), and sprouts applied with white light had superior amounts of activated SOD-like activity (52.69%). Research on dehydrated broccoli sprouts showed that sprouts dehydrated with cold air had superior amount of malic, citric, oxalic acid compared to sprouts dehydrated with hot air. In terms of vitamin levels, sprouts dehydrated with cold air had five times the normal amount of vitamin A and E, whereas sprouts dehydrated with hot air had higher amounts of vitamin C. Dehydration at low temperature also produced a higher amount of activated antioxidants (1.6 mg/mL of activated antioxidant ability, 63.04% of SOD-like activity, and 67.76% of hydroxyl radical scavenging). Our results show that antioxidant ability can vary by the type of photosynthesis and temperature level in which the sprouts are dehydrated. Therefore, thorough foundational data is required to product the most functional broccoli.

  • This study was carried out to investigate the effect of application of spent mushroom compost(SMC) on soil chemical properties and tomato growth. After the mushroom has been harvested, the SMC contains a lot of organic material, different microorganism and high density of mushroom hypha. SMC of white button mushroom(Agaricus bisporus) contained diverse microorganisms including fluorescent Pseudomonas sp. and actinomycetes. These isolates showed strong antagonistic to bacterial wi1t(Ralstonia solanacearum) and fusarium wi1t(Fusarium oxysporum) of tomato. The growth and sugar content of tomato showed no significant difference with other treatments by stage of maturity. The EC, exchangeable K and Ca contents of the soil during growing stage were increased in comparison to those of farmhouse practice, but available phosphate decreased. Microbial population in the soil in all growing stages showed no significant difference with other treatments, but yield of tomato decreased in some way in comparison to farmhouse practice. As the result of analysis on chemical property of soil and plant growth and yield of tomato, it seems likely that SMC of white button mushroom(Agaricus bisporus) may be used as substitute of practice compost on cultivation of tomato.

  • Pure red cell aplasia is unusual cause of anemia and a selective aplastic disorder that affects the erythroid series of the bone marrow. Fifty percent of all patients with red cell aplasia will have a thymoma. Twenty-five to 30% of those who undergo thymectomy will be cured. A 57-years-old man was admitted to the medical department of Korea University hospital with complaints. Physical examination reveals a sick looking man with a pale lip, anemic conjunctiva and subicteric sclera. On auscultation, coarse breathing sound and moist rale was heard on the right lung field. Neither the liver nor spleen was palpable. A blood count showed the erythrocytes to number 2,640,000/mm3 and hemoglobin to be 7.0gm/dl. A white blood cell count was 5,000/mm3 and a platelet count was 328,000/mm3 Reticulocyte count was 0.7%. Examination of the peripheral blood smear showed the red cell, to be normocytic and normochromic. Urine sugar was three positive and GTT was positive. The anterior-posterior and lateral view of Chest X-ray was suggestive of an anterior mediastinal mass. A bone marrow biopsy reveals absence of red cell precursors and a normal myeloid series and megakaryocytes. At thoracotomy in May 1980 an encapsulated, lobulated, benign thymoma, which measured 5x7x5 cm was removed, microscopic examination showed it was of the spindle cell type. The postoperative course was uneventful, but the patient never had a return of hemoglobin to the blood. The patient was discharged on the postoperative] 3 days. At postoperative 1 month, the patient was readmitted for bone marrow study and had no return of red cells to bone marrow. At now, patient has been treated with steroid and the further follow up study will be needed.

  • Physicochemical and organoleptic characteristics of Campbell Early red wines made by traditional method were investigated. The pH values of all Campbell Early red wines were ranged 3.0~3.3 during fermentation. The acidity value of Campbell Early red wine made by traditional method was 0.4~0.9%. Sucrose and alcohol contents were 6~7 Brix and 13.2~14.4% at the end of fermentation, respectively. Campbell Early red wine had the high sensory scores for color, aroma, taste, sharpness, after taste, and overall balance. Because Campbell Early red grapes are well fermented due to the rich fermentative sugar content, Campbell Early red wines made by adding EC-1118 yeast were shown to be the most appropriate.

  • Soybean curds were made from the mixture of soybean milk and cow's milk (raw milk) at the ratio of 10, 20, 30, 40, 50% (v/v), and then the general composition and mineral content, pH, yield, firmness by sensory evaluation and amino acid composition were investigated. As cow's milk addition increased, total sugar crude fat, crude protein, ash content, firmness, weight and volume of the soybean curd were increased. Whereas moisture content decreased, $Ca^{++}$, $K^{+}$, and Na$^{+}$ were increased, but $Mg^{++}$ and Fe$^{++}$ decreased. In sensory evaluation, color (white), firmness, flavor, and taste were higher than those of control as cow's milk increased. By adding cow's milk at the ratio of 10, 20, 30, 40%, and 50%, sulfur containing amino acid content such as methionine and cystine were enriched 1.31, 1.58, 1.67, 1.85, and 1.95 times, respectively.

  • Background Some diabetic feet heal without complication, but others undergo amputation due to progressive wounds. This study investigates the risk factors for amputation of diabetic feet. Methods A total of 55 patients who visited our institution from 2008 to 2012 were included in the study. The patients with abnormal fasting blood sugar levels, lower leg vascularity, and poor nutrition were excluded from the study group, and the wound states were unified. The patients were categorized into a treatment success group (n=47) and a treatment failure group (n=8), and their hemoglobin A1C (HgA1C), C-reactive protein (CRP), white blood cell count (WBC), and serum creatinine levels were analyzed. Results The initial CRP, WBC, and serum creatinine levels in the treatment failure group were significantly higher than that of the treatment success group, and the initial HgA1C level was significantly higher in the treatment success group. The CRP and WBC levels of both groups changed significantly as time passed, but their serum creatinine levels did not. Conclusions The initial CRP, WBC, and serum creatinine levels were considered to be risk factors for amputation. Among them, the serum creatinine level was found to be the most important predictive risk factor. Because serum creatinine represents the renal function, thorough care is needed for the feet of diabetic patients with renal impairment.

  • The purpose of this study was to investigate the quality characteristics of white bean based Yanggaeng containing various levels of pomegranate powder (0, 2, 4 and 8%, w/w). The pH values of Yanggaeng containing pomegranate powder were found to decrease when increasing the amount of pomegranate powder. However, moisture and sugar contents were increased (p<0.05). For color values, both L and b values were reduced by increasing the amount of pomegranate powder, while a values were increased significantly (p<0.05). In textural properties, the addition of pomegranate powder resulted in the increase of hardness, chewiness and gumminess, while cohesiveness and springiness decreased. Antioxidant activities, evaluated by DPPH radical scavenging capacity, and total phenolic substances content increased when increasing the amount of pomegranate powder. Results of descriptive analysis showed that by increasing the amount of pomegranate powder, some attributes such as the intensity of the flavor, sourness, hardness and chewiness increased (p<0.05), but there was no statistically significant difference in sweetness. In a preference test, Yanggaeng containing 4% pomegranate powder appeared to be the most preferred for all attributes tested including overall acceptability. It was concluded that Yanggaeng containing pomegranate can be prepared with good sensory properties and antioxidant activities, and the addition of 4% pomegranate powder was found to be ideal.
