OBJECTIVE: This study's aim was to develop and standardize a Korean version (SCoRS-K) of the Schizophrenia Cognition Rating Scale (SCoRS), which is used to evaluate the degree of cognitive dysfunction affecting the everyday functioning of people with schizophrenia. METHODS: Eighty-four schizophrenia patients with stable symptoms who were receiving outpatient treatment and rehabilitation therapy, and 29 demographically matched non-patient controls, participated in the study. Demographic data were collected, and clinical symptoms, cognitive function, and social function were evaluated to verify SCoRS-K's reliability and validity. Clinical symptoms were evaluated using the Positive and Negative Syndrome Scale and the Clinical Global Impression-Schizophrenia Scale. Cognitive function was evaluated using a short form of the Korean Wechsler Adult Intelligence Scale and the Wisconsin Card Sorting Test (WCST). Social function was evaluated using the Social and Occupational Functioning Assessment Scale, the Schizophrenia Quality of Life Scale, and the Social Functioning Scale. RESULTS: Data analysis demonstrated SCoRS-K's statistically significant reliability and validity. SCoRS-K has high internal consistency (Cronbach's alpha; patient 0.941, informant 0.905, interviewer 0.964); test-retest reliability [patient 0.428 (p=0.003), informant 0.502 (p<0.001), interviewer 0.602 (p<0.001); and global rating 0.642 (p<0.001)]. The mean scores of subjects were significantly higher than those of the controls (p<0.001), demonstrating SCoRS-K's discriminant validity. Significant correlations between the total scores and global rating score of SCoRS-K and those of the scales and tests listed above (except WCST) support SCoRS-K's concurrent validity. CONCLUSION: SCoRS-K is a useful instrument for evaluating the degree of cognitive dysfunction in Korean schizophrenia patients.

OBJECTIVE: The study’s aim was to develop and standardize a Korean version of the University of California San Diego Performance-based Skills Assessment (K-UPSA), which is used to evaluate the daily living function of patients with schizophrenia. METHODS: Study participants were 78 patients with schizophrenia and 27 demographically matched healthy controls. We evaluated the clinical states and cognitive functions to verify K-UPSA’s reliability and validity. For clinical states, the Positive and Negative Syndrome Scale, Clinical Global Impression-Schizophrenia scale, and Social and Occupational Functioning Assessment Scale and Schizophrenia Quality of Life Scale-fourth revision were used. The Schizophrenia Cognition Rating Scale, Short-form of Korean-Wechsler Adult Intelligence Scale, and Wisconsin Card Sorting Test were used to assess cognitive function. RESULTS: The K-UPSA had statistically significant reliability and validity. The K-UPSA has high internal consistency (Cronbach’s alpha, 0.837) and test-retest reliability (intra-class correlation coefficient, 0.381–0.792; p<0.001). The K-UPSA had significant discriminant validity (p<0.001). Significant correlations between the K-UPSA’s scores and most of the scales and tests listed above demonstrated K-UPSA’s concurrent validity (p<0.001). CONCLUSION: The K-UPSA is useful to evaluate the daily living function in Korean patients with schizophrenia.

Antiviral activity against Influenza virus of 14 Lactobacillus species isolated from food was monitored. Lactobacillus species were isolated from traditional Korean fermented food. Each live Lactobacillus was administered into the nasal cavity of SPF 6-week-old BALB/c mice. After the Lactobacillus treatment, Influenza virus (A/NWS/33/H1N1) was inoculated to each mouse. Clinical signs and mortality was monitored for 21 days. Each Lactobacillus strain showed various level of antiviral activity against Influenza virus. As a result of this study, this mouse experiment model, including intranasal treatment of live Lactobacillus species, could be effective model in evaluating immunomodulatory response of probiotics against respiratory viruses.

OBJECTIVE: To investigate the relationship between severity of peripheral polyneuropathy (PPN) and degree of depression and quality of life in chronic renal failure (CRF) patients on hemodialysis (HD). METHOD: Forty seven chronic renal failure patients on hemodialysis were recruited (22 male, 25 female, mean age of 63.17+/-12.52) and etiology, disease duration, hemodialysis duration, creatinine and hemoglobin were recorded. Motor and sensory nerve conduction studies were carried out on bilateral median, ulnar, tibial and peroneal nerves for diagnosis of polyneuropathy according to our laboratory criteria. The Korean version of Beck depression inventory (BDI) questionnaire translated into Korean for diagnosis of depression, and Korean version of Short Form 36 health survey (SF-36) questionnaire for measurement of general health level were measured in those diagnosed with uremic PPN. RESULTS: Out of 52 patients, 47 were diagnosed with polyneuropathy and mean score for BDI was 18.49+/-9.18. Mean scores for each of Mental Component Summary (MCS) and Physical Component Summary (PCS) of SF-36 were 50.84+/-15.42 and 47.41+/-18.68. The correlation between the scores and polyneuropathy were analyzed by Pearson coefficient. The MCS score was the significant (p<0.05) correlation parameter with depression (R=-0.635) and the PCS score was the only parameter with a significant (p<0.05) correlation with polyneuropathy (R=-0.340). CONCLUSION: Uremic polyneuropathy is commonly observed in chronic renal failure patients on hemodialysis. Depression in CRF with uremic PPN is affected by psychological factors other than the PPN itself.

BACKGROUND: Diamond Blackfan anemia (DBA), characterized by impaired red cell production, is a rare condition that is usually symptomatic in early infancy. The purpose of this study was to assess nationwide experiences of DBA encountered over a period of 20 years. METHODS: The medical records of 56 patients diagnosed with DBA were retrospectively reviewed from November 1984 to July 2010. Fifteen institutions, including 13 university hospitals, participated in this study. RESULTS: The male-to-female ratio of patients with DBA was 1.67:1. The median age of diagnosis was 4 months, and 74.1% were diagnosed before 1 year of age. From 2000 to 2009, annual incidence was 6.6 cases per million. Excluding growth retardation, 38.2% showed congenital defects: thumb deformities, ptosis, coarctation of aorta, ventricular septal defect, strabismus, etc. The mean hemoglobin concentration was 5.1+/-1.9 g/dL, mean corpuscular volume was 93.4+/-11.6 fL, and mean number of reticulocytes was 19,700/mm3. The mean cellularity of bone marrow was 75%, with myeloid:erythroid ratio of 20.4:1. After remission, 48.9% of patients did not need further steroids. Five patients with DBA who received hematopoietic transplantation have survived. Cancer developed in 2 cases (3.6%). CONCLUSION: The incidence of DBA is similar to data already published, but our study had a male predilection. Although all patients responded to initial treatment with steroids, about half needed further steroids after remission. It is necessary to collect further data, including information regarding management pathways, from nationwide DBA registries, along with data on molecular analyses.

PURPOSE: Recent studies have indicated that the p53 tumor suppressor gene and vascular endothelial growth factor (VEGF) play an important role in the angiogenic process of tumors. In this study, the correlation of the expressions of p53 and VEGF and the clinical features in gastric cancer were investigated. METHODS: The expressions of p53 and VEGF in gastric cancer were determined using immunohistochemistry on 98 randomly selected gastric cancer patients that had received curative resection. RESULTS: The expression of p53 and VEGF were observed in 51% and 50% of tumors, respectively. A significant correlation was found between p53 expression and the tumor histological type (P=0.045). The higher the TNM stage, the higher the observed level of p53 expression. The p53 and VEGF expression stati coincided in 70.4% of tumors, with a significant correlation found between the p53 and VEGF stati. Significantly worse survival rates were found in p53-positive and VEGF-positive patients than in those that were p53-negative and VEGF-negative. CONCLUSION: The present results indicated that p53 and VEGF expressions are useful in predicting the prognosis of patients with gastric cancer.

PURPOSE: Current diagnostic modalities frequently carry false negative evaluations, especially in micro-metastasis. Some metastases are identified incidentally during the operation for primary colorectal cancer. Our study was performed to assess the clinicopathological characteristics of intraoperatively diagnosed liver metastases, to analyze the survival and the prognosis, to compare the results with those for preoperatively diagnosed liver metastases. METHODS: Between July 1989 and December 2001, the cases of 78 patients who underwent treatment for intraoperatively diagnosed liver metastasis at our hospital were analyzed retrospectively. There were 375 patients who were diagnosed with liver metastasis preoperatively during the same period. Metachronous liver metastases were excluded. RESULTS: Intraoperatively diagnosed liver metastases mostly showed clinicopathological characteristics of primary colorectal cancer similar to those for preoperatively diagnosed liver metastases. On the other hand, the preoperative serum CEA level was significantly lower in the intraoperatively diagnosed group than it was in the preoperatively diagnosed group (P<0.001). For the metastatic lesion, the size of the metastasis was smaller in the intraoperatively diagnosed group than it was in the preoperatively diagnosed group (P=0.03). The two-year survival rate of the intraoperatively diagnosed group was significantly better than that of the preoperatively diagnosed group (71.6% vs. 58.4%; P=0.031). Prognostic factors of the intraoperatively diagnosed group were the number of liver metastases, a curative operation for the primary cancer, and an operation for the metastatic lesion. CONCLUSIONS: Intraoperatively diagnosed liver metastases had biologic features similar to those of preoperatively diagnosed liver metastases. The survival rate of the intraoperatively diagnosed group was better than that of the preoperatively diagnosed group, possibly due to the curative resection for the hepatic metastases. Therefore, aggressive treatment for primary and metastatic lesions is the therapeutic choice to improve patient's survival for intraoperatively diagnosed synchronous liver metastases.

Posttransplant lymphoproliferative disorder (PTLD) is one of the most serious complication occuring after solid organ transplantation. In general, mucosa-associated lymphoid tissue (MALT) lymphoma of stomach has not been considered to be part of this spectrum, because most of the MALT lymphoma are associated with not EBV but H.pylori. Until now, there have been only a few cases of MALT lymphoma after transplantation. We report case of gastric MALT lymphoma following renal transplantation and review the reported cases in the literatures.

Ginseng root, as a folk medicine, has been used in for eastern countries for thousands of years. Ginseng extract has been shown to have a variety of effects on the activity of the central nervous system, promoting simulation as well as inhibition of the cortical activity. A survey of the relevant literatures has indicated that the putative anxiolytic activity of red ginseng has not been scientifically investigated. Therefore, the present study was designed to assess anxiolytic effect of ginseng total saponinis(GTS). The putative anxiolytic effects of several fractions of GTS were investigated in mice using an elevated plus maze paradigm. Single dose administration of TS Fr.- I showed anxiolytic action in mice. Anxiolytic effect induced by TS Fr.-I was similar to that induced by diazepam. TS Fr.-II, TS Fr.-III and TS Fr.-IV did not show the anxiolytic action compared with that of TS Fr.-I. It was suggested that regulation of GABAergic neurotransmission may be important in the action of GTS. The Interaction of GTS fractions with benzodiazepine receptor was performed using rat cortical membranes. GTS inhibited the binding of [3H] Rp 15-1788 on the benzodiazepine receptor. Among from TS fractions, the binding activity of GTS in the TS Fr.-IV was highest, which did not show the anxiolytic activity. From these results, we conclude that GTS has anxiolytic action, and the is not related to benzodiazepine receptor binding activity.

It has been thought for many years that gastric adenocarcinoma almost never crosses the pylorus. Although this theory was generally accepted, several studies have refuted it. We report three cases of gastric adenocarcinoma direct spreading into the duodenum that was diagnosed by endoscopic duodenal biopsy and review the literature.
