  • The chemical components of barley (Jinmichapssal, Seodunchal, and Dusan No.8) and wheat (Alchanmil, Tapdongmil, and Olgeurumil) varieties were determined in terms of proximate compositions, minerals, fatty acids, amino acids and vitamin. There are significant differences in protein and lipid (p<0.00l, respectively), fiber (p<0.05) of barleys. There are significant differences in lipid contents (p<0.00l) of wheats. The major minerals of barley were Ca 24∼31 mg%, P 117∼129 mg%, Fe 1.7∼2.9 mg%, Na 13∼18 mg%, K 227∼73 mg%, Zn 1.1∼1.2 mg%, and Mg 38∼45 mg%. The content of Ca in Jinmichapssal was significantly higher than those in the other varieties (p<0.00l). The mineral contents of wheat were Ca 39∼67 mg%, P 172∼270 mg%, Fe 3.7∼5.6 mg%, Na 15∼17 mg%, K 537∼558 mg%, Zn 2.1∼2.3 mg% and Mg 106∼127 mg%. There are significant differences in Ca, P, Fe and Mg of 3 kinds of wheat. The barleys contain vitamin B$_1$ 0.27∼0.36 mg%, vitamin B$_2$ 0.07∼0.11 mg% and niacin 1.21∼1.44 mg%. The content of vitamin B$_1$ in Jinmichapssal and Seodunchal was significantly higher than that in Dusan No.8 (p<0.0l). The content of vitamin B$_2$ in Seodunchal (0.11 mg%) was significantly higher than those in the other varieties (p<0.0l). The content of niacin in barleys was no significant differences. The wheats contain vitamin B$_1$ 0.41∼0.52 mg%, vitamin B$_2$ 0.29∼0.39 mg% and niacin 1.86∼2.81 mg%. The contents of vitamin B$_2$ in Olgeurumil (0.39 mg%) and niacin in Tapdongmil (2.81 mg%) were considerably higher than those in the other varieties. The contents of vitamin B$_1$, B$_2$, niacin in wheats were higher than those of barleys. Major fatty acids in barley and wheat varieties were linoleic acid, palmitic acid and oleic acid, which comprised of about 90%∼92% of total fatty acid. The contents of lysine, valine, and tryptophan in Dusan No.8 were significantly higher than those in the other varieties. The contents of lysine, isoleucine in Tapdongmil were significantly lower than those in the other varieties. The content of amino acid in wheat was higher than those of barleys.

  • The quality characteristics of Goami by-product under the mixed enzyme treatment condition of $\alpha$-amylase and cellulase have been compared, and found the highest amount of soluble solids and reducing sugars at the $\alpha$-amylase treated group (A), and the contents revealed to show gradual decrease with the increase of cellulase content. The amounts of total dietary fiber and total sugars did not show large difference by both of enzyme concentration. The result of sugar analysis revealed the presence of all $G{\sim}G5$ in all treatment groups, and the content of malto-oligosaccharide recorded the highest content of 2,200 mg% at the $\alpha$-amylase treatment group (A). When the quality characteristic of the hydrolyzed powders manufactured by the optimum hydrolysis condition was compared, no significant color difference was found between samples. Among the contents of dietary fibers, insoluble dietary fiber was found to present in the lowest content of 6.95% at the Goami flour (GF) and the Goami by-product powder (GBPP) and Goami by-product hydrolysate powder (GBPHP) resulted the similar content around 14% and the highest soluble dietary fibers content was found in Goami by-product hydrolysate powder (GBPHP), which was followed by in the order of Goami by-product powder (GBPP) and Goami flour (GF), but the content variation was not large. The free amino acid was found to be highest in Goami by-product hydrolysate powder (GBPHP) followed by in the order of Goami by-product powder (GBPP) and Goami flour (GF). In the sugar analysis, the Goami by-product hydrolysate powder (GBPHP) was found with all $G{\sim}G5$ sugars by showing the highest amount of 1,800 mg% At the Goami by-product powder (GBPP), $G{\sim}G2$ sugars were detected with about 66 mg% and malto-oligosaccharides were not detected at the Goami flour (GF). Based upon the results, the functionality of Goami by-product hydrolysate powder (GBPHP) was found to be enforced compared to Goami flour (GF) and Goami by-product powder (GBPP), which allow us to expect it to be used as the various rice processing food source.

  • Background : Transforming growth factor-$\beta$(TGF-$\beta$) may play a role in a variety of fibroproliferative disorders including pulmonary fibrosis via the induction of extracellular matrix accumulation. TGF-$\beta$ not only stimulates extracellular matrix production, but also decreases matrix degradation. Interstial lung diseases have demonstrated marked expression of TGF-$\beta$. Methods : To evaluate the possible role of TGF-$\beta$ in human pulmonary fibrosis, by using neutralizing antibody of TGF-$\beta$ we investigated immunohistochemically the expression of TGF-$\beta$ in the formalin-fixed, paraffin-embedded tissue sections of the 5 normal cases for the control, and a couple of pieces of tissues taken out of 3 cases with idiopathic pulmonary fibrosis, 3 cases with ILD from bleomycin toxicity, 3 cases with ILD from sarcoidosis, and 3 cases with ILD from eosinophilic granuloma. Results : In the 5 normal cases for the control, the TGF-$\beta$ was expressed in bronchial and alveolar epithelial cells. Up-regulation of the TGF-$\beta$ expression was showed in the interstitial fibroblast cells of alveolar septa in 5 pieces and proliferated alveolar pneumocytes in 1 piece among 6 pieces tissues taken out of 3 cases with idiopathic pulmonary fibrosis. Also up-regulation of the TGF-$\beta$ expression was showed in alveolar lining pneumocytes, intra-alveolar mononuclear cells, and epithelioid cells in most of cases of ILD from bleomycin toxicity, sarcoidosis and eosinophilic granuloma. Conclusion : These findings suggest that up-regulation of the TGF-$\beta$are involved in pathogenesis of interstitial lung fibrosis from variety of causes.

  • The purpose of study was to introduce menus consisting of traditional local foods consumed in Busan, Korea. Five different types of formal meal menus with three side dishes and five different types of informal meal menus of which the main dish was not cooked rice were developed. Scores for the menu evaluations of formal and informal meals were higher than 7.9 (mean score of 6 category) on a 9.0 scale, suggesting that the menus were well constituted in terms of 'repeated use of ingredients and cooking methods', 'balance between main and side dishes', 'frequency of usage of local products', 'nutritional balance', 'variety of dishes', and 'popularization'. Nutritional values of menus were compared with those of the KDRI for men aged 30~49 years old. All ten menus reflected a low calorie, high protein, and high fiber diet. Mineral contents (Ca, Fe, Zn, K, and Na) of the above 10 menus were higher than those of the KDRI. On the other hand, vitamin contents slightly differed according to meal type due to limited fresh vegetable usage in the winter season. Vitamin A, B ($B_1$, $B_2$, niacin, $B_6$), C, folic acid, and E contents in the five informal menus were found to be proper or greater than those of the KDRI. However, for the formal meal menus, all vitamin contents except that of vitamin A in menu type I was lower than that of the KDRI. Content of vitamin C in menu type V was approximately 50% of that of the KDRI. The most preferred formal menu was consisted of Ogokbap, Boreumjijimi, Dongchimi, Namul (nine varieties), Gaksaeksanjeok (Shark/Daegu/Gunso), and Gimgui. And that for informal menu was consisted of Honghapjuk, Baechu kimchi, Dongchimi, Miyeokseolchi, Kodari jorim, and Neulgeun hobakjeon. Suggestions for providing more fresh vegetables or fruits for certain types of meals (formal meal type V) were offered. Additionally, pre-preparation of sea products were required to reduce Na contents.

  • 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.

  • Objective of research is obtain fundamental data of carbonized wood wastes for soil condition, de-ordorization, absorption of water, carrier for microbial activity, and purifying agent for water quality of river. The carbonization technique and the properties of carbonized wood wastes(wood-based materials) were analyzed. Proximate analysis showed the wood-based materials contains 0.37~2.27% ash, 70~74% volatile matter, and 17~20% fixed carbon. As carbonization temperature was increased, the charcoal yield was decreased. However, no difference in charcoal yield was found due to time increase. The specific gravity after the carbonization decreased about 30~40% comparing to green wood. The charcoal had 1.08~4.18% ash, 5.88~13.79% volatile matter, and 80.15~90.94% fixed carbon. The pH of plywood and particleboard(pH 9 at $400^{\circ}C$, pH 10 at $600^{\circ}C$ and $800^{\circ}C$) made charcoals was higher than that of fiberboard. The water-retention capacity was not affected by the carbonization temperature and time. The water-retention capacity within 24h was about 2~2.5 times of sample weight, and the Equilibrium moisture content(EMC) became 2~10% after 24h. EMC of charcoal from the thinned trees were 9.40~11.82%($20^{\circ}C$, RH 90%), 6.87~7.61%($20^{\circ}C$, RH 65%), and 1.69~2.81%($20^{\circ}C$, RH 25%). EMC of charcoal from the wood-based materials under $20^{\circ}C$, relative humidity(RH) 90% was similar to EMC of charcoal from the thinned trees(9~11 %). However, under $20^{\circ}C$, RH 25.65%, EMC of charcoal from the wood-based materials were higher(2~3%) than EMC of charcoal from the thinned trees. Every charcoal from the wood-based materials fulfilled the criteria in JWWA K 113-1947.

  • Background: Current vascular prostheses are still inadequate for reconstruction of small-diameter vessels. Autologous pericardium can be a good alternative for this purpose as it already possesses good blood compatibility and shows a mechanical behavior similar to that of natural arteries. However, the clinical use of autologous pericardial tissue as a small-diameter vascular graft has limitations due to mixed outcomes from uncertain biological behavior and difficulty to gain reliable patency results in animal experiments. To study this issue, we implanted fresh and glutaraldehyde-treated autologous pericardium as small-diameter arterial grafts in dogs, and compared their time-related changes histologically. Material and Method: As a form of 5mm-diameter arterial graft, one pair of autologous pericardial tissue was used for comparison between the glutaraldehyde-treated and the glutaraldehyde-untreated grafts in the bilateral carotid arteries in the same dog. The patency of the grafts were evaluated at regular intervals with Doppler ultrasonography. After the predetermined periods of 3 days, 2 weeks, 1 month, 3 months and 6 months, the grafts in each animal were explanted. The retrieved grafts were processed for light and electron microscopic analyses following gross observation. Result: Of 7 animals, 2 were excluded from the study because one died postoperatively due to bleeding and the other was documented as one side of the grafts being obstructed. All 10 grafts in the remaining 5 dogs were patent. Grossly, a variable degree of thromboses were observed in the luminal surfaces of the grafts at 3 days and 2 weeks, despite good patency. Pseudointimal smooth blood-contacting surfaces were developed in the grafts at f month and later. By light microscopy, mesothelial cell layers of the pericardial tissue were absent in all explanted grafts. Newly formed endothelial cell layers on the blood-contacting surface were observed in both the glutaraldehyde-treated and fresh grafts at 3 months and later. The collagen fibers became degraded by fragmentation in the fresh graft at 1 month and In the glutaraldehyde-treated graft at 3 months. At 6 months, the collagen layers were no longer visible in either the glutaraldehyde-treated or fresh grafts. By electron microscopy, a greater amount of coarse fibrin fibers were observed in the fresh grafts than in the glutaraldehyde-treated grafts and, more compact and well-arrayed layers were observed in the glutaraldehyde-treated grafts than in the fresh grafts. Conclusion: The glutaraldehyde-treated small-diameter pericardial arterial grafts showed a better endothelialization of the blood-contacting surface and a slower fragmentation of the collagen layers than the fresh grafts, although it has yet to be proven whether these differences are so significant as to affect the patency results between the groups.

  • Purpose : Menkes disease is an X-linked recessively inherited disorder caused by the mutation of the ATP7A gene encoding copper-transporting P-type AT Pase. The phenotypic features are progressive neurological degeneration, mental retardation, loose skin, and vascular complications. Early diagnosis and treatment are very important for the prognosis of Menkes disease. Here, we describe nov el mutations of the ATP7A gene and prenatal diagnosis by mutation analysis. Methods : Five unrelated Korean Menkes patients were included in this study. They presented with depigmented wool-like hair, progressive neurologic deterioration, and hypotonia in infancy. Serum copper and ceruloplasmin levels w ere decreased. Brain magnetic resonance imaging revealed tortuous intracranial vessels. Mutation analysis has been carried out using cDNA from cultured skin fibroblasts or genomic DNA from peripheral leukocytes. Prenatal diagnosis was performed in two cases using chorionic villi samples or amniocytes. Results : Four novel mutations have been identified from four different families; c.3511+1G>A (p.E1099_N1171delinsMfsX 18), c.4005+5 G>A (p.V1268_R1335del), c.1870_2172del (p.S624_Q724del), and c.3352 G>A (p.G1118S). T he remaining one was previously reported (c.1933 C>T (p.V 1268_R1335del)). On prenatal DNA analysis, one w as diagnosed as normal, while the other turned out to be a female heterozygote with p.S624_Q724del mutation of the ATP7A gene. Conclusion : We identified 4 novel mutations of the ATP7A gene. Prenatal diagnosis in families at risk is critical in order to choose preventiv e options including an early treatment with copper-histidine therapy or therapeutic termination. Most mutations of the ATP7A gene were frame-shift mutations and prenatal diagnosis has been successfully carried out.

  • In approximate composition, crude protein, lipid, ash, crude fiber, and N-free extract constituted 14.70%, 3.10%, 6.90%, 18.20%, and 57.10%, respectively, in Korean safflower flowers, compared to 12.60%, 2.70%, 5.80%, 16.40% and 62.50%, respectively, in Chinese safflower flowers. This indicated that Korean safflower flowers surpassed their Chinese counterparts except in terms of N-free extract. Free sugars such as fructose, glucose, and sucrose were proven to be dominant in both domestic and Chinese safflower flowers, while little xylose was contained. For content of polyphenolic compound, Korean safflower flowers contained 13.85% water soluble extract and 9.70% MeOH extract, compared to 9.39% and 7.04%, respectively, for the Chinese variety, confirming the higher levels in the Korean variety. For fatty acids, (Ed- the following results are not presented in ratio form) saturated fatty acids and unsaturated fatty acids comprised 6.80% and 93.20% in Korean safflower flowers and 16.0% and 84.0% in Chinese safflower flowers, respectively. Linoleic, oleic, and palmitoleic acids comprised 75.30%, 11.60%, and 3.40% in Korean safflower flowers, and 66.70%, 11.20%, and 6.10% in the Chinese variety, respectively. Of amino acids, essential amino acids comprised 46.67% in Korean safflower flowers and 36.79% in the Chinese variety. Moreover, total essential amino acids in Korean safflower flowers were higher than those of their counterparts. Non-essential amino acid comprised 65.17% in the Korean variety and 54.49% in the Chinese. In terms of mineral content, Korean safflower flowers contained more Ca, Cu, Fe and Mn than those of China, while Chinese safflower flowers contained more A1, Ba, Mg, K, Na, Zn, Sr and P.

  • The goal of this study was to investigate the effects of dietary mugwort on the proximate composition, volatile basic nitrogen (VBN), thiobarbituric acid reactive substance (TBARS) and fatty acid in chicken meats. One hundred sixty broiler chicks (1 d old) were assigned to one or four dietary groups: Control; commercial feed supplemented with 1% mugwort (T1); commercial feed with 3% mugwort (T2) and commercial feed with 5% mugwort (T3). After 42 d, broilers from each group were slaughtered and meat samples were vacuum packaged and stored at $4{\pm}1^{\circ}C$ over a period of 0, 1,2,3, and 4 wk. Chicken breast was not influenced by all treatments in moisture, crude protein and crude fiber, while crude fat was lowered (p<0.05) in chickens fed with the T2 and T3 diets compared to the control and T1 diets. All treatments with mugwort diets tended to have decreased VBN values for chicken breast and thigh compared to control. As storage time increased, VBN was increased for all chickens (p<0.05). No significant differences in TBARS were observed among all treatments at 0 wk. TBARS values were reduced with the T2 and T3 diets and initially increased from 0 through 3 wk, then abruptly decreased at 4 wk. Dietary mugwort supplementation resulted in increased stearic acid (excepted T2) and oleic acid and decreased linoleic acid. Stearic acid in thigh meat was decreased in the T1, T2 and T3, however linoleic acid levels tended to increase with mugwort powder supplementation. It is concluded that dietary mugwort has a positive effect on increasing unsaturated fatty acid contents and decreasing saturated fatty acids.
