In order to find out the status of health care of the old aged people (age of 65 and over) in a rural area, a study was carried out, through analyzing the data of health care clinic for 207 old aged people with geriatric diseases, and of questionnired survey for 84 old aged people with geriatric diseases in a rural community. Su Dong-Myun. Nam Yang Zu-Gun, Kyung Gi-Do, Korea, during the year of 1989. The following results were obtained. 1) The composition rate of population of age of 65 and over was 9.8% in total, and sex-specific composition rate was 9.3% in male and 10.4% in female. 2) Utilization rate of health care clinic for old aged people with geriatric diseases was the highest rate with 37.9%, through individual letters at the first time, and showed gradually decreasing tendency afterward. 3) In the means of utilization advices to health care clinic for the old aged people. the individual letters(37.9%) at the first time were more effective than public information of the old aged hall or/and Myun office(18.4%). 4) In opinion on utilization of health subcenter-health care clinic for the old aged people "will utilize"(59.5%) was the highest and "do not know"(26.2%) "be difficult to utilize" (9.5%) and "will not utilize"(4.8%) were in the next order. 5) Out of 84 respondents, the old aged people With geriatric diseases, 73.8%(about three-fourths) of them answered "their diseases to the aggravated" (29.8%) "not to be changed"(25.0%) and "to be unknown"(19.0%), and the others(26.2% of them) "to be changed for the better". 6) Out of 62 respondents(the old aged people), answered their geriatric diseases not to be changed for the better, "no curative effect" was the highest with 43.5% of them. "could not know" (33.9%), "would not treat"(19.4%) and "could not be treated"(4.8%) were in decreasing order. 7) The old aged people, responded their diseases to be changed for the better, answered that they(patients) should make themselves(68.2%) responsible for basic effort of health care. However the old aged people responded their diseases not to be changed for the better answered that they should impute the responsibility of basic effort for health care to medical facilities or other conditions(63.0%). 8) In the reason of failure that the old aged people responded their geriatric diseases not to have curative effect, mis-control of regular habits of daily life was the highest(57.1%), and failure of taking selected medicine steadily(28.6%), and abuse of medicines(14.3%) were in decreasing order. 9) The reason order of being changed for the better that the old aged people responded their diseases to have curative effect, was keeping and control of regular habits of daily life (46.7%), taking selected medicines steadily(33.3%) and others (20.2%) respectively. 10) The courses of geriatric diseases itself are so chronic, duplicate and uncertain, and the old aged people activities for disease control are so slow, various and uncertain that continuous health education in home or/and community unit must be essential factors for effective geriatric health care.

Purpose: The H. pylori cagA gene, vacA gene and iceA gene are considered to be important virurence factors that have been implicated in the development of gastric adenocarcinoma. It was reported that the presence of IS605 elements may be responsible for rearrangements and lead to partial or total deletions of the cag pathogenicity island (PAI) and the virulence of cag PAI may be changed. However, different results regarding the association between these virulence factors and clinical disease have been reported from different geographic regions. This study evaluated the relationship between H. pylori virulence factors such as cagA, vacA, iceA, IS605 and gastric adenocarcinoma. Materials and Methods: H. pylori isolates were obtained from 54 infected patients (24 cases of gastric adenocarcinoma, 30 cases of control). H. pylori isolates were identified by PCR with ureC gene and 16S rRNA. PCR was performed to examine cagA, vacA, iceA and IS605 genotypes. Results: Significant difference was found in the negative rates of cagA between gastric adenocarcinoma group and control ($62.5\%\;vs.\;33.3\%$ P=0.033). No significant difference was found in the prevalence of iceA, vacA between gastric adenocar cinoma and control. The genotype of cagA+ vacA s1-m1 iceA1 was predominant in H. pylori isolates irrespective of the clinical outcome. IS605 in PAI was not found in gastric adenocarcinoma gruop and control. The positive rates of IS605 in genome were $33.3\%$ in gastric adenocarcinoma group and $36.7\%$ in control (P>0.05). In gastric carcinoma, the positive rate of $cagA^{+}/IS605$ was lower than in control ($12.5\%\;vs\;40.0\%$, P=0.025) and the positive rate of cagA-/IS605 was higher than in control ($54.2\%\;vs\;23.3\%$, P=0.02). Conclusion: H. pylori virulence factors had not related significantly with gastric adenocarcinoma. Further study is needed to examine the specificity of H. pylori strains.

Purpose: Vascular endothelial growth factor (VEGF) is one of the most important growth factors for metastatic tumors. To clarify the role of VEGF-A and C in patients with peptic ulcer disease (PUD) or gastric cancer (GC), we evaluated the expression levels of these two molecules. We also analyzed the effect of Helicobacter pylori infection on VEGF-A and C expression levels. Materials and Methods: Patients with dyspepsia who needed diagnostic endoscopy were selected and divided into three groups: nonulcer dyspepsia (NUD), PUD, and GC, according to their endoscopic and histopathological results. Fifty-two patients with NUD, 50 with PUD, and 38 with GC were enrolled in this study. H. pylori infection was diagnosed by the rapid urease test. After RNA extraction and synthesis of cDNA, the expression levels of VEGF-A and C were determined by quantitative reverse transcriptase polymerase chain reaction. Results: The VEGF-C expression level in the PUD and GC groups was significantly higher than that in the NUD group. Moreover, the VEGF-A expression level in the PUD and GC groups was higher than in the NUD group, although the differences were not statistically significant. Significant positive correlations were also observed between the expression levels of these two molecules in the PUD and GC groups. In addition, the expression levels of these two molecules were higher in H. pylori positive patients with PUD or GC than in H. pylori negative patients of the same groups; however, these differences did not reach statistical significance. Conclusions: Up-regulation of VEGF-C expression during gastric mucosal inflammation may play a role in the development of peptic ulcers or GC.

Multiple myeloma (MM) is a malignant disease caused by an abnormal proliferation of plasma cells, of which the prognostic factors include chromosomal abnormality, ${\beta}$-2 microglobulin, and albumin. Recently, the term chromothripsis has emerged, which is the massive but highly localized chromosomal rearrangement in response to a one-step catastrophic event. Many studies have shown an association of chromothripsis with the prognosis in several cancers; however, few studies have investigated it in MM. Here, we studied the association between chromothripsis-like patterns and treatment resistance or prognosis. First, we analyzed nine MM cell lines (U266, MM.1S, RPMI8226, KMS-11, KMS-12-BM, KMS-12-PE, KMS-28-BM, KMS-28-PE, and NCI-H929) and bone marrow samples of four patients who were diagnosed with MM by next-generation sequencing-based copy number variation analysis. The frequency of the chromothripsis-like pattern was observed in seven cell lines. We analyzed the treatment-induced chromothripsis-like patterns in KMS-12-BM and KMS-12-PE cells. As a result, breakpoints and chromothripsis-like patterns were increased after drug treatment in the relatively resistant KMS-12-BM. We further analyzed the patients' results according to the therapeutic response, which was divided into sensitive and resistant, as suggested by the International Myeloma Working Group. The chromothripsis-like pattern was more frequently observed in the resistant group. In the sensitive group, the frequency of the chromothripsis-like pattern decreased after treatment, whereas the resistant group showed increased chromothripsis-like patterns after the treatment. These results suggest that the chromothripsis-like pattern is associated with treatment response in MM.

Background: The aim of this study was to examine the influence of body mass index (BMI) on the development of acute kidney injury (AKI) in critically ill patients in intensive care unit (ICU). Methods: Data of patients admitted to medical ICU from December 2011 to May 2014 were retrospectively analyzed. Patients were classified into three groups according to their BMI: underweight (< $18.5kg/m^2$), normal ($18.5-24.9kg/m^2$), and overweight (${\geq}25kg/m^2$). The incidence of AKI was compared among these groups and factors associated with the development of AKI were analyzed. AKI was defined according to the Risk, Injury, Failure, Loss of kidney function, and End-stage (RIFLE) kidney disease criteria. Results: A total of 468 patients were analyzed. Their mean BMI was $21.5{\pm}3.9kg/m^2$, including 102 (21.8%) underweight, 286 (61.1%) normal-weight, and 80 (17.1%) overweight patients. Overall, AKI occurred in 82 (17.5%) patients. The overweight group had significantly (p<0.001) higher incidence of AKI (36.3%) than the underweight (9.8%) or normal group (15.0%). In addition, BMI was significantly higher in patients with AKI than that in those without AKI ($23.4{\pm}4.2$ vs. $21.1{\pm}3.7$, p<0.001). Multivariate analysis showed that BMI was significantly associated with the development of AKI (odds ratio, 1.893; 95% confidence interval, 1.224-2.927). Conclusion: BMI may be associated with the development of AKI in critically ill patients.

Background : Interstitial cystitis is a disorder of the bladder characterized by urgency and frequency of urination, and pelvic pain. The cause of interstitial cystitis is not clear. Modern medical treatments include behavioral therapy, medication, intravesical infusion therapy, and surgical treatment, but the goal of treatment is based on symptom relief rather than a cure. According to a recent report, in an animal model, oriental medicine treatment, Yukmijihwang-tang improved the symptoms of interstitial cystitis. However, clinical studies and experimental research are lacking. Objectives : In this study, We investigated Chuknyojetong-tang, acupuncture, moxibustion and bee venom effect on interstitial cystitis. Methods : We targeted 25 patients diagnosed with interstitial cystitis at the university hospital and treated them for more than one month. We used acupuncture, Chuknyojetong-tang, and bee venom. The effects were evaluated using ICSI and ICPI at the begin of treatment and at the end of treatment. Results : All of the 25 patients were female, average age was $53.3{\pm}13.5$ years, and the average month of disease-duration was $69.0{\pm}59.8$. The duration of treatment was $8.0{\pm}5.4$ months, and 60% of patients were improved. After treatment, we used correlation coefficient method, multiple regression analysis. ICSI difference increased as treatment period increased. ICPI difference increased as age decreased. Total difference also increased as treatment period increased. These results imply that treatment effect was improved. Conclusions : These findings suggest that oriental medicine therapy using Chuknyojetong-tang, acupuncture, moxibustion, and bee venom would be very effective on interstitial cystitis.

Type I interferons (IFNs) are critical mediators of the innate immune system to defend viral infection. Interferon regulatory factor (IRF) and signal transducer and activator of transcription (STAT) play critical roles in type I IFN production in response to viral infection. Luteolin is natural polyphenolic compounds that have anti-inflammatory, cytoprotective and anti-carcinogenic effects. However, the mechanism of action and impact of luteolin on innate immunity is still unknown. In this study, we examined the effects of luteolin on the lipopolysacchride (LPS)-induced inflammatory responses. Luteolin inhibited Type I IFNs expression of mRNA and increased interleukin(IL)-10 expression of mRNA. Next, we examined the protective effects of IL-10 using IL-10 neutralizing antibody (IL-10NA). Blockade of IL-10 action didn't cause a significant reduction of Type I IFNs than LPS-induced luteolin pretreatment. Pretreatment of luteolin inhibited the level of IRF-1, and IRF-7 mRNA and the nuclear translocation of IRF-3. Also, luteolin reduced the activation of STAT - 1, 3. Theses results suggest that luteolin inhibits LPS-induced the production of Type I IFNS by both IRFs and STATs not IL-10 and may be a beneficial drug for the treatment of inflammatory disease.

An isolate of Ampelomyces quisqualis 94013(AQ94013) was selected as an effective agent for biological control against cucumber powdery mildew. In order to develop mass production technique, six cereal media made with barley, rice, mille and brown rice, sorghumand rice seed were tested. Among them, barley medium was the best for the growth and conidial production of AQ94013. Optimum temperature for the mass production of AQ94013 was $25^{\circ}C$ and followed by $20^{\circ}C$ and $30^{\circ}C$. Light radiation inhibited conidial production of AQ94013 since number of conidia formed on barely medium under continuous light or 12 hrs alternative light were much less than cultured in darkness. Tthe conidia produced on the medium at $30^{\circ}C$ maintained the parasitic ability to Sphaerotheca fusca for 30 days. A culture method of AQ94013 in barley liquid medium with adding barely power(40 g/l) in darkness for five days at $25^{\circ}C$using a 30 l-fermenter was very effective for mass production of conidia.
