The fact that long-term use of proton pump inhibitors (PPIs) aggravates corpus atrophic gastritis in patients with Helicobacter pylori infection has been proven clinically and experimentally. Corpus atrophic gastritis is a known risk factor for gastric cancer. Therefore, gastric neoplasia might be associated with the long-term use of PPIs. One of the causes of worsening corpus atrophic gastritis, leading to the development of adenocarcinoma, might be bacterial overgrowth under conditions of hypochlorhydria. The production of potentially carcinogenic N-nitrosocompounds by nitrosating organisms under conditions of hypochlorhydria might be associated with carcinogenesis. Interactions between bile acids, pH, and H. pylori might also contribute to carcinogenicity, especially in patients with gastro-esophageal reflux disease (GERD). The concentration of soluble bile acids, which have bactericidal or chemorepellent properties toward H. pylori, in gastric contents is considerably higher in patients undergoing continuous PPI therapy than in healthy individuals with normal acid production. Under these circumstances, H. pylori might colonize the stomach body rather than the pyloric antrum. Hypergastrinemia induced by PPI administration might promote the development of gastric cancer. Because the main cause of corpus atrophic gastritis is H. pylori infection, and not PPI administration, H. pylori infection should be eradicated before starting long-term PPI therapy.

Purpose: In Oriental medicine, menstruation is a significant index of women's health. Especially high school girls often have various menstrual problems. We think that students who have menstrual problem have some symptoms in relation to an etiological cause. So we had carried out this study to investigate association of DSOM scores and an abnormality of menstruation in oriental medicine. Methods: First we have 2137 high school girls answer to menstrual questionnaire that we made and DSOM, next investigated the pathogenic factor of DSOM which effect dysmenorrhea and menorrhagia using regression model. Logistic regression analysis indicate as follows. Results: 1. In comparison with dysmenorrhea, Qi depression(氣滯), blood stasis(血瘀), dampness (濕), phlegm(痰) is associated positively and liver(肝) negatively. The sensitivity is 64.3%, and the specificity is 75.1%. 2. In comparison with menorrhagia, Blood deficiency(血虛), Qi depression(氣滯), blood stasis(血瘀) is associated positively and liver(肝) negatively. The sensitivity is 53.9%, and the specificity is 76.1%. Conclusion: In this study, that has been carried out to organize the diagnosis of dysmenorrhea and menorrhagia in Oriental medicine, we can see that the disease factors of them were correlated with our Medical theory.

전 세계적으로 위선암은 두 번째로 많은 암 사망의 원인을 차지하며 지역에 따라 유병률의 차이를 보인다. 한편 위장관 간질종양은 다양한 악성도를 갖는 드문 질환이다. 지금까지의 연구결과에 따르면 이 두 종양은 서로 상이한 발병기전을 가지고 있는 것으로 생각되며, 두 종양이 한 환자에서 동시성으로 발병하는 경우는 매우 드물다. 환자는 64세 남자로, 우연히 발견된 위의 종괴 및 궤양 병변으로 본원에 의뢰되었다. 수술 전 검사를 시행한 뒤 위전절제술을 시행하였고, 9 cm 크기의 위장관 간질종양 및 유문부의 조기위암이 동시에 존재하고 있는 것으로 확인되었다. 이러한 현상은 드물지만 위선암의 유병률이 높은 지역에서는 일어날 수 있는 일일 것으로 생각되며, 지금까지 보고된 문헌들에 대한 고찰과 함께 보고하는 바이다.

Canine juvenile cellulitis (CJC) is a well-recognized lymphocutaneous disease that is seen in young dogs. CJC seemed to be immunologic disorder and may have a hereditary aspect. Exact pathogenesis and cytokine regulation on the immune system of CJC are not clear. CJC was diagnosed in two puppies hospitalized in Veterinary Teaching Hospital of Chungbuk National University. To investigate the cytokine regulation on CJC, RT-PCR was performed with CJC affected dogs. RT-PCR 1 was performed with whole blood sample (CJC-B) and fine needle aspirates of the inguinal lymph node (CJC-LN) from case 1-dog, which included $TNF-\alpha,$ $IL-1\beta,$ $IFN-\gamma,$ IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12 and $\beta-actin.$ Blood sample from a normal dog (N-B) served for a negative control of RT-PCR 1 (case 1). $IFN-\gamma,$ IL-2, IL-4, IL-5, IL-8, IL-10 and IL-12 transcripts were not expressed in all sample. $TNF-\alpha$ and $IL-1\beta,$ were not transcripted from CJC-B but from CJC-LN. On RT-PCR 2 (case 2), submandibular lymph node aspirates were used and $TNF-\alpha,$ IL-10, $IFN-\gamma$ and $IL-1\beta$ were expressed. $TNF-\alpha,$ 1L-10 and $IFN-\gamma$ were secreted from activated macrophages enhance the inflammation in tissue. These results imply that abnormally increased macrophages secret $TNF-\alpha$ and $IL-1\beta$ in the affected lymph nodes, which attract neutrophils and cause inflammation in CJC.

The cause and pathogenesis of inflammatory bowel disease remain unknown and no definitetherapy exists until now. The present study was conducted to investigate the anti-inflammatory effectsof a herbal preparation (HemoHIM) in colitis induced by 30 mg of trinitrobenzene sulfonic acid (TNBS)in rats. Sprague-Dawley rats were divided into 5 groups. Each group was treated with 1 mg ofHemoHIM/ml of drinking water, 4 mg of HemoHIM/ml of drinking water, 50 mg of HemoHIM/kgof body weight (i.p. once every other day) or 10 mg/kg of HemoHIMof body weight (i.p. onceevery other day) from the next day. After 2 weeks, rats were sacrificed and morphologic featuresof colons were examined. Ulceration, adhesion, thickening and dilatation were noticed in the colonicmucosa after TNBS instillation. Intraperitoneal injection of HemoHIM (50 and 100 mg/kg of bodyweight) showed the anti-inflammatory effect on adhesion, thickening, dilatation, ulceration, and theinhibition effect on damage score by 72.7% and 90.9%, respectively. Histologically, the colon of TNBS-treated rat showed inflammatory cell infiltration by polymorphonuclear cells, multiple erosive lesionsignificant improvement in these symptoms. The results obtained suggest marked anti-inflamatoryactivity of the HemoHIM at the dose levels examined.

Osteoporosis is one of the diseases caused by accumulation of effects from complex interactions between genetic and environmental factors. Aging is the major cause for osteoporosis, which normally increases skeletal fragility and bone fracture especially among the elder. "Omics" refers to a specialized research field dealing with high-throughput biological data, such as genomics, transcriptomics, proteomics or metabolomics. Integration of data from multi-omics has been approved to be a powerful strategy to colligate biological phenomenon with multiple aspects. Actually, integrative analyses of "omics" datasets were used to present pathogenesis of specific diseases or casual biomarkers including susceptible genes. In this study, we evaluated the proposed relationship of novel susceptible genes (TREML2, HTR1E, and GLO1) with osteoporosis, which genes were obtained using multi-omics integration analyses. To this end, SNPs of the susceptible genes in the Korean female cohort were analyzed. As a result, one SNP of HTR1E and five SNPs of TREML2 were identified to associate with osteoporosis. The highest significant SNP was $rs6938076^*$ of TREML2 (OR=0.63, CI: 0.45~0.89, recessive P=0.009). Consequently, the susceptible genes identified through the multi-omics analyses were confirmed to have association with osteoporosis. Therefore, multi-omics analysis might be a powerful tool to find new genes associated with a disease. We further identified that TREML2 has more associated with osteoporosis in females than did HTR1E.

The pathogenetic mechanisms of anemia in patients with chronic liver disease were observed. Seventeen patients with moderate to advanced hepatic diseass were studied by various methods. Only patients without previous blood loss were included: 14 had cirrhosis, 2 had active chronic hepatitis, and one had inferior vena cava obstruction with associated liver cirrhosis. The followings were the results: 1. The anemia based on red blood cell count, Hb., and Ht. was found in 76.5-78.6% of the patients. 2. Red cell indices indicated that normo-macrocytic and normochromic anemia was present is the majority of the patients. 3. No evidence of megaloblastic anemia was found on the basis of the morphological examinations. 4. Serum iron, TIBC, % saturation and iron content in the bone marrow indicated that iron deficiency anemia was present in about half of the patients. 5. In the view of the erythrocyte dynamics, primary increase in the red cell destruction was ascribed to the cause of the anemia. 6. Decrease in the red cell survival time was not correlated with MCV, % saturation and S.L. ratio. Also, hemoglobin level was not correlated with MCV, % saturation and $T_{50}Cr$. Therefore, multiple causes may be involved in the pathogenesis of the anemia. 7. Anemia as determined by the red cell volume was found in only 60% of the patients. It may be possible that hemodilutional anemia is present.
