This study was performed to produce WBM (wheat and barley mixture) bread containing molokhia powder with quality characteristics and antioxidant activities. Analysis of the chromaticity of WBM prepared with molokhia powder showed that; the lightness and redness were decreased, but yellowness was increased. In mechanical properties, hardness, gumminess, and chewiness were significantly increased as the amount of molokhia powder was increased. However, cohesiveness was significantly decreased. In sensory evaluation, WBM bread containing 1.5% of molokhia powder (MB1.5) showed an overall high preference level. The total polyphenol content of molokhia powder EtOH extract and MB1.5 were 29.19 and 58.18 mg TAE/g, respectively. The total flavonoid contents of molokhia powder EtOH extract and MB1.5 were 20.62 mg and 33.25 mg RE/g, respectively. The radical scavenging ability ($IC_{50}$) of DPPH ($IC_{50}$) for molokhia powder EtOH extract and MB1.5 was 31.04 and $58.18{\mu}g/mL$, respectively while that of ABTS was 33.25 and $54.15{\mu}g/mL$, respectively. The ${\alpha}-glucosidase$ inhibitory effects of molokhia powder EtOH extract and MB1.5 were 494.88 and $814.88{\mu}g/mL$, respectively. MB bread containing 1.5% molokhia powder showed antioxidative effects and ${\alpha}-glucosidase$ inhibitory activity, meaning that not only molokhia but also MB1.5 bread has the potential to prevent chronic degenerative diseases such as diabetes.

In order to investigate a pathogenesis of liver damage induced by skin burn, thermal injury was induced by scald burn on entirely dorsal surface in rats (total body surface area 30%) except for inhalated injury. At 5 and 24 h after scald bum, biochemical assay and morphological changes in skin tissue, serum and liver tissue were examined. The effects of bum injury on the levels of glutathione, lipid peroxide and on the activities of oxygen free radical generating and scavenging enzymes have been determined in association with observing of histologic and ultrastructural changes, measuring the protein concentration in plasma, and counting the number of intravascular polymorphonuclear leukocytes. The activity of xanthine oxidase, an enzyme of oxygen free radical generating system. was elevated (p<0.01) in serum, but not in skin and in liver tissue. Futhermore, thermal injury decreased not only the protein concentration in plasma but also the number of leukocytes, that indicates induction of edema formation with protein exudation and inflammation by neutrophil infiltration into the internal organs. These data suggest that acute dermal scald burn injury leads to liver damage, that is related to elevation of xanthine oxidase activity in serum. Xanthine oxidase may be a key role in the pathogenesis of liver damage induced by skin burn.

목적: 위식도접합부선암의 임상병리학적 특성은 서구와 아시아 간의 많은 차이를 보인다고 알려져 있다. 그러나, 한국의 경우 위식도접합부선암의 유병율이 매우 낮고 이에 대한 연구 또한 부족하다. 따라서 저자들은 우식도접합부선암의 Siewert 분류에 따른 임상병리학적 특성을 조사하여 서구와 다른 국내 위식도접합부선암의 특성을 연구하고자 하였다. 대상 및 방법: 2004년 5월부터 2008년 2월까지 본원에서 위암으로 수술을 시행 받은 환자들을 대상으로 수술소견 및 병리 사진을 토대로 Siewert 분류법에 따라 위식도접합부선암을 분류하고, 의무기록을 바탕으로 환자들의 임상병리학적 특성들을 조사하였다. 결과: 위식도접합부선암은 전체 1,778예 중 70예(3.9%)였다. Siewert 1형은 3예(4.3%)로 매우 드물었으며, 2형과 3형이 각각 30예(42.8%) 37예(52.8%)였다. 2형이 3형에 비하여 평균연령이 높았으나(64세 vs 59세, P=0.049), 남녀비에는 차이가 없었다. 2형과 3형간에 Barrett 식도의 발현 정도나 Lauren 분류의 차이는 없었으나, 저분화암의 빈도는 3형에서 유의하게 높았다(P=0.045). 68예(97.1%)에서 근치적 절제가 시행되었으며, 각 아형간에 TNM 병기의 차이는 없었다. 결론: 국내의 위식도접합부선암은 매우 드물며 특히 1형의 유병율이 매우 낮다. 본 연구에서 서구의 보고와 부분적으로 일치하지 않는 병리학적 특성을 보였다. 향후 보다 많은 환자들을 대상으로 한국인의 위식도접합부선암의 특성을 연구할 필요가 있다. Purpose: Siewert's classification of adenocarcinoma of the esophagogastric junction (AEG) has been widely adopted, but there is a wide discrepancy of the clinicopathological features of AEG of the Asian patients as compared to that of the Western patients. The aim of this study was to investigate the clinicopathological characteristics of AEG according to the Siewert classification. Materials and Methods: Among the patients who underwent surgery for gastric carcinoma in our institution between May 2004 and February 2008, the AEG patients were selected based on their operation records and the photographs according to Siewert's classification. Results: There were 70 AEG patients (3.9%) among the total of 1,778 patients. There were 3 patients (4.3%) with type I, 30 patients (42.8%) with type II and 37 patients (52.8%) with type III. Curative resection (R0) was achieved in 68 cases (97.1%). No significant differences in gender, stage, Barrett's esophagus and the proximal margin were found between the patients with type II and type III AEG. The patients with type III were younger than the patients with type II (59 vs 64 years, respectively, P=0.049). Well differentiated histology (P=0.045) and the intestinal type (P=0.055) were significantly more frequent in the patients with type II as compared with that in the patients with type III. Conclusion: There was a striking difference of the Asian patients from the Western patients for the incidence of AEG (and especially type I). Some of the differences between type II and type III patients were similar to those of the previous Western studies. A large study is needed to investigate whether these features are typical in the Korean population.
Streptozotocin 유도 당뇨성 흰쥐의 혈당, 전해질 및 지질대사에 삼백초 추출액이 미치는 영향
김한수,Kim, Han-Soo 한국생명과학회 2006 생명과학회지 Vol.16 No.6
Streptozotocin(STZ 55 mg/kg BW., I.P. injection)으로 유발된 당뇨성 Sprague Dawley계 수컷 흰쥐에 있어서, 삼백초 생리활성물질 추출액(3.5 g% extract)의 섭취에 의한 혈당, 전해질, 혈청 지질개선효과 및 당질대사 이상 등에 관여하는 효소의 활성 변동을 생리생화학적 측면에서 검토하기 위하여 본 실험을 수행하였다. 기본식이만을 급여한 대조군인 Normal군을 비롯한 STZ 당뇨 유발군(NSW군), 당뇨 유발에 삼백초 잎 추출액을 섭취시킨 군(NSSL군) 및 당뇨 유발에 삼백초 뿌리 추출액을 섭취시킨 군(NSSR군)을 5주간 실험 사육하였다. 혈당 농도는 당뇨 유발군에 삼백초 추출액을 급여하므로서 유의적으로 저하됨을 관찰할 수가 있었다. 또한 혈청 총 콜레스테롤, 동맥경화지수, LDL, LDL- 콜레스테롤, 유리 콜레스테롤, 콜레스테롤 에스테르 비, 중성지방 및 인지질 농도 등은 삼백초 추출액을 섭취시킨 군(NSSL군, NSSR군)에서 농도가 유의성 있게 감소되는 것으로 나타났다. 한편, HDL-콜레스테롤 및 총 콜레스테롤에 대한 HDL-콜레스테롤 비 등은 삼백초 추출액 섭취(NSSL군, NSSR군)에 의해서 유의성 있게 증가 되는 것으로 나타났다. 혈청 중의 전해질(Na, K, Cl) 및 creatinine 농도는 STZ으로 당뇨 유발군에 삼백초 추출액을 섭취시킴으로서 유의성 있는 농도 저하 효과를 보였다. 또한, 혈청 중 aminotransferase(AST, ALT), creatine phosphokinase(CPK), lactate dehydrogenase(LDH) 및 alkaline phosphatase(ALP)의 활성은 STZ으로 당뇨 유발 시킨 후 삼백초 추출액을 섭취시킴으로서 저하되는 것으로 나타났다. 한편, 삼백초 잎(NSSL군)과 뿌리(NSSR군) 추출액 섭취에 따른 혈당, 각 종 지질 성분 및 효소 활성치의 두 군 간의 비교는 삼백초 잎이 뿌리 추출액에 비하여 다소 효과적인 차이를 보였으나 유의성 있는 변화는 보이지 않았다. 이상과 같은 결과들을 미루어 볼 때, 삼백초 중의 생리활성물질이 STZ으로 유발된 당뇨성 흰쥐의 혈당 조절 기능이상 및 혈청 지질대사 이상 등에서 오는 각종 질환의 예방 및 개선 작용에 효과가 있을 것으로 생각된다. The purpose of this study was to observe the effects of the feeding physiological activity substance in Saururus chinensis Baill extract on the improvement of the blood glucose, electrolyte (Na, K, CI) concentration and lipid metabolism in the serum of streptozotocin (STZ, 55 mg/kg B.W., I.P. injection)-induced hyperglycemic rats fed the experimental diets for 5 weeks. Concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, triglyceride (TG) and phospholipid (PL) in serum were significantly higher in the hyperglycemic group (group NSW), STZ (I.P.)+Saururus chinensis Baill leaf 3.5 g% extract group (group NSSL) and STZ (I.P.)+Saururus chinensis Baill root 3.5 g% extract group (group NSSR) than those in the control group (group Normal, basal diet+water). But the concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, TG and PL in serum were remarkably lower in the groups NSSL and NSSR than those in the NSW, whereas the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration in the groups NSSL and NSSR were significantly higher than in the group NSW. Electrolyte and creatinine concentrations in serum were significantly lower in the groups NSSL and NSSR than those in the group NSW. The activities of aminotransferase (AST, ALT), creatine phosphokinase (CPK), lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) in serum were remarkably lower in the groups NSSL and NSSR than in the hyperglycemic group NSW. However, no significance was found in the comperative effect of the groups NSSL and NSSR. From the above results, it was suggested that Saururus chinensis Baill was effective in the improvement of the blood glucose, electrolyte, glucide and lipid metabolism in serum of STZ-induced hyperglycemic rats.

In this paper, the blast resisting performance of the CFT columns was compared with that of the typical reinforced concrete columns and the reinforced concrete columns strengthened with steel jacket. AUTODYN which is a specialized hydrocode for the analysis of explosion and impact was used to simulate the structural behavior of the columns under the blast loading. The interaction between concrete and surrounding steel plates was modeled with two modeling methods, friction option and join option. The results from the frictional experiment were adopted to determine the friction coefficient in friction option. The CFT columns which have a similar P-M diagram with a reinforced concrete column were also investigated to compare the blast resisting performance and the static load resisting performance. According to the analysis results, the CFT column and the column with steel jacket showed much better blast resisting performance than the normal reinforced concrete column.

Laryngopharyngeal reflux disease (LPRD) is the result of retrograde flow of gastric contents to the laryngopharynx. Laryngoscopic findings and special questionnaires are first step of diagnosis of LPRD. Empiric trials of Proton pump inhibitor' test (PPI test) is recommended as treatment and diagnosis. However confirmation of reflux is then recommended primarily in patients with persistent symptoms despite acid-suppressive therapy. The 24 hour ambulatory double pH monitoring has been a gold standard method in diagnosis of LPRD even though it has some limitation. The combined multichannel intraluminal impedance and pH monitoring is a new-rising test tool. It can detect acid/non-acid, liquid/gaseous reflux and clearance of refluxate. The water siphon test is also used for diagnosis of LPRD.

Background and Objectives : The most important two factors of the voice production are the respiratory function which is the power source of voice and the glottic closure that transform the air flow into sound signals. The purpose of this study was to investigate the differences between trained singers and untrained controls under varying intensity at a constant vocal pitch by simulataneous using the airway interruption method and electroglottography(EGG). Materials and Methods : Under two different intensity condition at a constant vocal pitch(/G/), 20(Male 10, Female 10) trained singers were studied. Mean flow rate(MFR), subglottic pressure(Psub) and intensity were measured with aerodynamic test using the Phonatory function analyzer. Closed quotients(CQ), jitter and shimmer were also investigated by electroglottography using Lx speech studio. These data were compared with that of normal controls. Results : MFR and Psub were increased on high intensity condition in all subject groups but there was no statistically significance. Statistically significant increasing of CQ. were observed in male trained singers on high intensity condition (untrained male : 51.31${\pm}$3.70%, trained male :55.52${\pm}$6.07%, p=.039). Shimmer percent, one of the phonatory stability parameters, was also decreased statistically in all subject groups(p<.001). Conclusion : The trained singers' phonation was more efficient than untrained singers. The result means that the trained singers can increase the loudness with little changing of mean flow rate, subglottic pressure but more increasing of glottic closed quotients.

This study aimed to investigate the improvement effect of 5% (w/w) mung bean (Phaseolus aureus L.) on lipid composition and protein concentration in hyperlipidemic rats. Seven-week-old male (Sprague-Dawley) rats were divided into four groups (n=6, each), and fed experimental diets containing mung bean meal [basal diet+5% (w/w) mung bean (BM), basal-hyperlipidemic diet+5% (w/w) mung bean (BHM)], basal-hyperlipidemic diet (BH), and control (basal diet, BD). Lipid composition in the mung bean diet groups (BM and BHM) evidenced significant reductions in serum total cholesterol, low-density lipoprotein cholesterol, atherosclerotic index, cardiac risk factor, triglyceride, phospholipid, free cholesterol, cholesteryl ester, blood glucose, nonesterified fatty acid, and an elevation in high-density lipoprotein cholesterol. The serum albumin/globulin ratio was increased in mung bean diet-supplemented rats compared to that in hyperlipidemic rats (p < 0.05). Total calcium, phosphorus and potassium concentrations in sera were higher in the BM, BHM and BD groups than in the BH group. Concentrations of sodium and chlorine in sera were lower in the mung bean diet-supplemented groups than in the hyperlipidemic group. The in vivo experiments showed that ingestion of mung bean was effective in improving lipid composition, protein concentration, and blood glucose.
