Obesity may cause metabolic syndrome and adult diseases. This study was undertaken to investigate the ameliorative or useful effects of beanleaves on inflammation and liver damage in obese rat models. Rats were divided into three groups: a control group (normal diet, n=6), a fat diet group (45%?fat diet, n=7), and a bean leaf group (45%?fat+Korean bean leaves diet, n=7). Body weights in the bean leaf group were lower than those of the fat group (P<0.05). Serum tumor necrosis factor?α (TNF?α) and prostaglandin E₂ (PGE₂) concentrations were lower in both the control and bean leaf groups than in the fat group (P<0.001). TNF?α concentrations in the bean leaf group were slightly higher than in the control group but statistically significant (P<0.05). The bean leaf group histologically exhibited lower fatty degeneration, spotty necrosis, and leukocyte infiltrations in hepatic tissues than those of the fat group. In the homogenized liver tissues, the cyclooxygenase?2 (COX?2) gene was only expressed in the fat group. The gene expression levels of hepatic TNF?α, inducible nitric?oxide synthase, peroxiome proliferator?activated receptor?α (PPAR?α), poly (ADP?ribose) polymerase (PARP), and transforming growth factor?β1 (TGF?β1) were weaker in the bean leaf group than in the fat group. These results suggest that adding bean?leaves to the diet may ameliorate obesity?induced systemic inflammation and liver damage and that bean leaves may be a useful food for preventing obesity and thereby metabolic syndrome and adult diseases

Ulcerative colitis (UC) is a chronic inflammatory disorder of the gastrointestinal tract that affects the large bowel, Its etiology remains controversial. However, an infectious or immunologic origin is considered the primary cause. The onset of UC is typically slow and insidious, but some patients may present acutely with symptoms mimicking infectious colitis. We report a case of ulcerative colitis mimicking acute hemorrhagic colitis at initial presentation. A 60-year-old man was referred to Yeungnam University Hospital for bloody diarrhea and abdominal pain. Sigmoidoscopy revealed mildly edematous mucosa in the rectum and hyperemic mucosa with petechiae in the sigmoid colon. The patient was treated with antibiotics for several days, and his symptoms improved. However, after one month, his bloody diarrhea relapsed. Follow-up sigmoidoscopy revealed mucosal friability in the rectum and sigmoid colon. He was diagnosed with ulcerative colitis, and his symptoms were improved with mesalazine and a steroid enema.

KIOM-MA128 is a novel oriental herbal medicine which is for atopic dermatitis and asthma. The purpose of this study was to develop on analytical method of arctiin in rat plasma after oral administration of KIOM-MA128. Analyte was separated on a Atlantis dC18 reverse phase column, using gradient mobile phase (A:B = acetonitrile: 0.1% formic acid in water) at a flow rate of 0.3 mL/min. Detection was performed by electrospray positive ionization mass spectrometry using multiple reaction monitoring of the transitions of arctiin at m/z 552.4 → 372.8 and internal standard (carbamazepine) at m/z 237.0 → 194.5. The limit of quantification was 1 ng/mL for arctiin. The precisions were lower than 15% and the accuracy was between – 12.21 and 3.2%. The maximum concentration found in plasma samples was 4.1 ng/mL. The present method was successfully developed for detecting arctiin in plasma and this results would be utilized to the further study.

The study has been carried to examine a new disease of carnation caused by Alternaria isolate, which was found in Gim Hae, Gyoungnam province and the suburbs of Busan City, recently. 1. The pathogen was identified as Alternaria dianthi Stevens & Hall which has not been described in Korea. The common name of the disease was given as IB Ma Reum Byung(carnation blight). 2. Morphological studies of the fungus have shown a wide variation in shape, size and septation of conidia. The size of conidia formed on carnation leaf lesions in field is 22.8-101.2μ(av. 60.4μ)×10.1-27.8μ(av. 18.6μ), which was larger than those on potato dextrose agar in vitro. 3. Of 13 carnation varieties tested, Boston, Linda and Red Alaska were highly susceptible, and Angel, Flamingo Sim, William Sim and Yo Soo were moderately susceptible whereas Brauns Yollw Sim, Colquate, Imp Sisney Little Field, Cardinal Sim, La Reve Salmon Sim and Safari were slightly susceptible to the fungus under the condition of artificial infection.

This paper proposes an SSSC based on 3-level half-bridge inverters. The dynamic characteristic of the proposed SSSC was analyzed by EMTP simulation, assuming that the SSSC is inserted in the transmission line of the one-machine-infinite-bus power system. The proposed SSSC has six 3-level half-bridge inverters per phase, which poperates in PWM mode. The proposed SSSC generates a quasi-sinusoidal output voltage by 90 degree phase shift to the line current. The proposed SSSC does not require the coupling transformer for voltage injection, and has a flexibility in operation voltage by increasing the number of series connection.

This study of research are to identify causalities among reliability, repeat, women's customer satisfaction and women's customer loyalty in travel products and to identify the factors by which reliability and repeat are influenced. However, this research is different from the previous ones in the sense that both reliability and repeat are considered in the study of the relationship between women's customer satisfaction/loyalty and reliability/repeat in travel products. Conclusively, customer satisfaction and loyalty are positively related not with the reliability but with the repeat. Besides, women's customer loyalty is significantly influenced by the reliability, repeat and the customer satisfaction. This indicates that companies in the tour agents have to develop a segmentation strategy for the reliability which is more socially and ethically allowable than the repeat.

백서에서 신 허혈성 손상에 미치는 칼슘 길항제의 효과

Renal ischemia is one of the most common causes of acute renal failure. Four factors related to the pathogenesis of acute renal failure are vasoconstriction, decreased glomerular filtration rate, tubular back leak of filtrate, and intratubular obstruction. The cellular response to renal ischemic insults include decreased content of adenosine trihosphate, lipid peroxidation induced membrane degradation, alteration in cellular pH, and calcium or phospholipase induced mitochondrial dysfunction. Much attention has been given to the role of increased cellular calcium as a pathogenetic contributor to cell injury during ischemia. Author studied the protective effects of calcium antagonists on cellular injury during renal ischemia in rat. To investigate the protective role of these agents, author measured the amount of malondialdehyde(MDA) and the enzyme activities of free radical scarvengers-superoxide dismutase(SOD), catalase and glutathione peroxidase from non-pretreated group and calcium antagonists pretreated groups in control, ischemia and reflow subgroups. The results were summerized as follows: 1) The amount of MDA in non-pretreated group was higher in the reflow compared with the control(<p<0.01). But, in all pretreated groups, there was no statistically difference in the amount of MDA. 2) The SOD activity in non-pretreated group was lower in both the ischemia and the reflow compared with the control (P<0.05). But, in both verapamil and trifluoperazine-pretreated groups, there was no statistically difference in the SOD activity. 3) Both catalase and glutathione peroxidase activities in non-pretreated group were lower in both the ischemia and the reflow compared with the control (P<0.05). But in all pretreated groups, there was no statically difference in both catalase and glutathione peroxidase activities. These results suggest that free radical mediated ischemic injury by renal artery clamp in rat can be protected by intraperitoneal pretreatment with calcium antagonists. As trifluoperazine has a protective effect in renal ischemia, the calcium activated calmodulin dependent enzyme may play a role in renal ischemic injury.
