Two virulence factors of Helicobacter pylori, cagA and vacA, have been known to play a role in the development of severe gastric symptoms. However, they are not always associated with peptic ulcer or gastric cancer. To predict the disease outcome more accurately, it is necessary to understand the risk of severe symptoms linked to other virulence factors. Several other virulence factors of H. pylori have also been reported to be associated with disease outcomes, although there are many controversial descriptions. H. pylori isolates from Koreans may be useful in evaluating the relevance of other virulence factors to clinical symptoms of gastric diseases because the majority of Koreans are infected by toxigenic strains of H. pylori bearing cagA and vacA. In this study, a total of 116 H. pylori strains from Korean patients with chronic gastritis, peptic ulcers, and gastric cancers were genotyped. The presence of virulence factors vacAs1c, alpA, babA2, hopZ, and the extremely strong vacuolating toxin was found to contribute significantly to the development of severe gastric symptoms. The genotype combination vacAs1c/alpA/babA2 was the most predictable determinant for the development of severe symptoms, and the presence of babA2 was found to be the most critical factor. This study provides important information on the virulence factors that contribute to the development of severe gastric symptoms and will assist in predicting clinical disease outcomes due to H. pylori infection.

본 실험에서 흰쥐에 실험적으로 급성위염, 위궤양 및 십이지장궤양을 유발하고 지유 에틸아세테이트분획을 투여하여 항위염 및 항궤양에 미치는 영향을 검토하였던 바 다음과 같은 결과를 얻었다. 지유 에탄올 추출물을 n-헥산, 클로르포룸, 에틸아세테이트 및 n-부타놀과 물로 계통분획하여 농축하고 in vitro에서 항산화력을 측정한 결과 에틸아세테이트분획이 가장 우수하였다. 지유 에틸아세테이트분획 (SOL & SOH)의 HCI-EtOH급성위염에 대한 억제율은 각각 $27.7\%$, $31.7\%$로 대조약물로 사용된 cimetidine(CMT, $47.2\%$)의 억제효과에는 미치지 못했으나 CON에 비해 우수하였다. Indomethacin유발 위궤양에서, SOL & SOH의 위궤양억제율은 각각 $48.28\%$, $51.08\%$로 대조약물로 사용된 CMT($58.26\%$)의 억제효과에는 미치지 못했으나 CON에 비하며 유의 성있는 억제효과를 나타냈다. Shay 위궤양에서, 지유 에틸아세테이트분획을 십이지장에서 위내로 투여하였을 때 궤양 억제율은 SOL이 $42.86\%$로 CON에 비하여 억제되었으나 유의성 있는 효과는 아니었으며, 용량을 증량하여 투여한 SOH는 $47.71\%$로 대조약물인 omeprazol(OMP)의 저해효과($62.00\%$)에 미치지는 못했으나 CON에 비해 유의적민 효과를 나타내었다. 위액량 및 총위산분비량에서, 지유 에틸아세데이트분획 투여로 CON에 비하여 $32.11\%$와 $47.69\%$, $24.28\%$와 $34.69\%$의 감소로 유의성 있는 효과를 나타냈으며 OMP($55.69\%$, $41.62\%$)에 근접하게 감소되었다. pepsin 활성은 지유 에틸아세테이트분획 투여로 CON에 비해 각각 $19.55\%$, $\%21.45$가 저하되었으나 유의성있는 변화는 아니었다. 수침 $\cdot$ 구속 스트레스에 의해 유발된 궤양의 경우, SOL는 궤양억제율이 $9.23\%$ 로 CON와 유사하게 출혈을 동반한 깊은 궤양이 관찰되었으나 용량을 증량하여 투여한 SOH는 $48.45\%$로 CON에 비해 궤양의 깊이도 얕아졌고 출혈을 동반한 궤양도 감소되어 유의적인 억제율을 나타내었다. Cysteamine 유발 십이지장궤양에서, CMT는 유발된 십이지장 궤양을 CON에 비해 $54\%$ 정도 억제하여 우수한 항궤양효과를 나타냈고 시료투여군인 SOL 및 SOH는 CMT보다 우수하지는 않았으나 약 $35\∼42\%$ 정도의 궤양억제율을 나타냈다. 이상의 실험결과에서 지유의 항위염 및 항궤양효과는 항산화물질에 의한 결과로 판단되어지며, 앞으로 위염 및 위궤양 개선을 위한 건강 기능성 식품으로 개발이 기대된다

This study was designed to construct a structural model for health promoting behavior of patients with chronic disease. The hypothetical model was developed based on the literature review and Pender's health promotion model. Method: Data was collected by questionnaires from 1748 patients with chronic disease in General Hospital from December 1999 to July 2000 in Seoul. The disease of subject were cardiac disease included hypertension peptic ulcer, pulmonary disease included COPD and asthma, DM, and chronic kidney disease. Data analysis was done with SAS 6.12 for descriptive statistics and PC-LISREL 8.13 Program for Covariance structural analysis. Results: 1. The fit of the hypothetical model to the data was moderate, it was modified by excluding 4 path and including free parameters to it. The modified model with path showed a good fitness to the empirical data (χ2=591.83, p<.0001, GFI=0.97, AGFI= 0.94, NNFI=0.95, RMSR=0.01, RMSEA=0.05). 2. The perceived benefits, perceived barriers, self-efficacy, self- esteem, and the plan for action were found to have significant direct effect on health promoting behavior of chronic disease. 3. The health concept, health perception, emotional state, social support were found to have indirect effects on health promoting behavior of chronic disease. Conclusion: The derived model in this study is considered appropriate in explaining and predicting health promoting behavior of patients with chronic disease. Therefore, it can effectively be used as a reference model for further studies and suggested implication in nursing practice.

Helocobacter phylori is the major cause of gastritis, peptic ulcer, and a principal risk factor for gastric cancer. As the firs step towards a vaccine against H. pylori infection, Hy.pylori urease was expressed and purified as a recombinant apoenzyme (rUrease) in E. coli. In order to develop an effective immunization protocol using rUrease, the host immune responses were evaluated after the oral immunization of mice with rUrease preparations plus cholera toxin relative to various conditions, such as the physical nature of the antigen, the frequency of the booster immunization, the dose of the antigen, and the route of administration. The protective efficacy was assessed using a quantitative culture following an H. pylori SS1 challenge. It was demonstrated that rUrease, due to its particulated nature, was more superior than the UreB subunit as a vaccine antigen. The oral immunization of rUrease elicited significant systemic and secretory antibody responses, and activated predominantly Th2-type cellular responses. The bacterial colonization was significantly reduced (~100-fold) in those mice immunized with three or four weekly oran doses of rUrease plus cholera toxin (p<0.05), when compared to the non-immunized/challenged controls. The protection correlated well with the elicited secretory IgA level against rUrease, and these secretory antibody responses were highly dependent on the frequency of the booster immunization, yet unaffected by the dose of the antigen (25-200$\mu\textrm{g}$). These results demonstrate the remarkable potential of rUrease as a vaccine antigen, thereby strengthening the possibility of developing an H. pylori vaccine for humans.

Galla Rhois is a nest of parasitic bug, Mellaphis chinensis Bell, in Rhus chinensis Mill. Galla Rhois has been used for the therapy of diarrhea, peptic ulcer, hemauria, etc., that showed various antiinflammatory activity, and other biological properties. We studied the effect of Galla Rhois water extract(GRWE). The cytotoxic activity of GRWE in HL-60 cells was increased in a concentration-dependent manner. GRWE was cytotoxic to HL-60 cells, with $IC_50$ of $100{\mu}g/m{\ell}$. Treatment of GRWE to HL-60 cells showed the fragmentation of DNA in a concentration manner, suggesting that these cells underwent apoptosis. In addition, the flow cytometric analysis revealed GRWE concentration-dependently increased apoptotic cells with hypodiploid DNA content and arrested G1 phase of cell cycle. These results indicate that GRWE may have a possibility of potential anticancer activities. Treatment of HL-60 cells with GRWE was induced activation of caspase-3, caspase-8 and proteolytic cleavage of poly(ADP-ribose) polymerase. Also, caspase-3 was directly activated via caspase-8 activation. GRWE also caused the release of cytochrome c from mitochondria into the cytosol. GRWE-induced cytochrome c release was mediated by caspase-8-dependent cleavage of Bid and Bax translocation. These results suggest that caspase-8 mediates caspase-3 activation and cytochrome c release during GRWE-induced apoptosis in HL-60 cells.

Purpose: Herpes zoster is a common dermatologic disease characterized by unilateral pain and vesicular lesions over the unilateral sensory dermatomes being caused by the reactivation of Varicella zoster virus and its incidence seems to be increasing recently. In case of involving the ganglion of the fifth cranial nerve(trigeminal nerve), it can descend down the affected nerve into skin, then producing an eruption in the dermatome. Among the patients, about 40 - 50% had associated conditions such as diabetes mellitus, hypertension, pulmonary tuberculosis, liver diseases, peptic ulcer, hypothyroidism, pharyngitis but rare facial trauma. Methods: Retrospective study was done for 3 cases of Herpes zoster from May 2000 to May 2007, which had been treated with acyclovir and steroid. Results: The clinical course was uneventful. Follow-up length was about 3 months. After treatment, the patients became stable and there was no complications. Conclusion: Herpes zoster was commonly associated with systemic disorders and the treatment duration was prolonged in associated diseases. But herpes zoster occurring specifically at the site of previously traumatized facial skin has not yet been reported. We experienced the treatment of herpes zoster developing within recent operative facial scar and three cases are presented with the review of literatures. Finally, facial trauma might be a risk factor for herpes zoster in traumatized patients.

Purpose: With previous methods based on only age and location, there are many difficulties in identifying the etiology of acute abdominal pain in children. We sought to develop a new systematic classification of acute abdominal pain and to give some helps to physicians encountering difficulties in diagnoses. Methods: From March 2005 to May 2010, clinical data were collected retrospectively from 442 children hospitalized due to acute abdominal pain with no apparent underlying disease. According to the final diagnoses, diseases that caused acute abdominal pain were classified into nine groups. Results: The nine groups were group I "catastrophic surgical abdomen" (7 patients, 1.6%), group II "acute appendicitis and mesenteric lymphadenitis" (56 patients, 12.7%), group III "intestinal obstruction" (57 patients, 12.9%), group IV "viral and bacterial acute gastroenteritis" (90 patients, 20.4%), group V "peptic ulcer and gastroduodenitis" (66 patients, 14.9%), group VI "hepatobiliary and pancreatic disease" (14 patients, 3.2%), group VII "febrile viral illness and extraintestinal infection" (69 patients, 15.6%), group VIII "functional gastrointestinal disorder (acute manifestation)" (20 patients, 4.5%), and group IX "unclassified acute abdominal pain" (63 patients, 14.3%). Four patients were enrolled in two disease groups each. Conclusion: Patients were distributed unevenly across the nine groups of acute abdominal pain. In particular, the "unclassified abdominal pain" only group was not uncommon. Considering a systemic classification for acute abdominal pain may be helpful in the diagnostic approach in children.
