The purpose of this study was to investigate food sanitation status in elderly welfare facilities and assess the performance of food sanitation practices. Twenty elderly welfare facilities out of 85 located in Seoul with a capacity of fewer than 50 persons participated. The food sanitation status of worktable, kitchen utensils (knives, cutting boards, ladles, spoons), and tableware and bowls were examined by ATP bioluminescence. The results found that the ATP value of knife was the highest. Those of ladles appeared relatively higher than others. Meanwhile, the tableware and bowls, although washed everyday after meals, had the lowest ATP value. This study also conducted a survey on the food sanitation practices of 32 cooking employees in the 20 facilities. Fifty-six percent were in their 40s, and 53% had graduated from high school. More than half (66%) of them had no certification of cooking. Half of the respondents had worked for at least 5 years in food service facilities, and had received food sanitation training. Among them, 31% said they applied food sanitation training while working, and 47% responded the training was very helpful. The foodservice employees demonstrated good food sanitation practices. The results show that food sanitation performance of the workers significantly differed according to their age, education level, total work experience in food service facilities, chef certification, and prior food sanitation experience.

OBJECTIVES: Organizational culture has been important in field of organizational behavior research for the past decade. Although there has been a growing interest in the organizational culture and organizational effectiveness, there is few research in health care field. This study was carried out to investigate the relationship of organizational culture and organizational effectiveness at general hospital. METHODS: Data was collected by self-administrated questionares. Organizational cultures were measured by using Likert scale. A general hospital in Kyunggi-Do was selected and survey was conducted to 675 workers. Data was analyzed with computer package, PC- SPSS. RESULTS: There were four types of organizational culture in this hospital : consensual culture, developmental culture, hierarchical culture, rational culture. Many workers recognized their culture as rational culture and developmental culture. This finding showed that the hospital had both human related and task related climate. There were some differences in recognition of sub-organizational culture by occupational group, but perceived organizational culture was in accordance with sub-organizational culture in general. Multiple regression analysis and multiple logistic regression analysis were conducted to find the relationship of organizational culture and organizational effectiveness. As a result, developmental culture showed a strong relationship with organizational commitment and job-satisfaction. CONCLUSIONS: These results showed that types of organizational culture were significantly related to organizational effectiveness and understanding the existing culture is essential to develope their organizational effectiveness.

BACKGROUND: It has been recently noticed that type 2 diabetes (T2D), one of the most common metabolic diseases, causes a chronic low-grade inflammation and activation of the innate immune system that are closely involved in the pathogenesis of T2D. Cordyceps militaris, a traditional medicinal mushroom, produces a component compound, cordycepin (3'-deoxyadenosine). Cordycepin has been known to have many pharmacological activities including immunological stimulating, anti-cancer, and anti-infection activities. The molecular mechanisms of cordycepin in T2D are not clear. In the present study, we tested the role of cordycepin on the anti-diabetic effect and anti-inflammatory cascades in LPS-stimulated RAW 264.7 cells. METHODS: We confirmed the levels of diabetes regulating genes mRNA and protein of cytokines through RT-PCR and western blot analysis and followed by FACS analysis for the surface molecules. RESULTS: Cordycepin inhibited the production of NO and pro-inflammatory cytokines such as IL-1beta, IL-6, and TNF-alpha in LPS-activated macrophages via suppressing protein expression of pro-inflammatory mediators. T2D regulating genes such as 11beta-HSD1 and PPARgamma were decreased as well as expression of co-stimulatory molecules such as ICAM-1 and B7-1/-2 were also decreased with the increment of its concentration. In accordance with suppressed pro-inflammatory cytokine production lead to inhibition of diabetic regulating genes in activated macrophages. Cordycepin suppressed NF-kappaB activation in LPS-activated macrophages. CONCLUSION: Based on these observations, cordycepin suppressed T2D regulating genes through the inactivation of NF-kappaB dependent inflammatory responses and suggesting that cordycepin will provide potential use as an immunomodulatory agent for treating immunological diseases.

PURPOSE: Oral mucositis is a common toxicity of radiation or chemotherapy, which is used a treatment for head and neck cancer. We investigated effects of recombinant human epidermal growth factor (rhEGF) on radiation-induced oral mucositis in rat model. MATERIALS AND METHODS: Spraque-Dawley rats (7 per group) exposed to a single dose of 25 Gy (day 0) on their head, except for one group, were randomly divided into un-treated, vehicle-treated, and two rhEGF- treated groups. Rats were topically applied with rhEGF (15 or 30 microgram/oral cavity/day) or vehicle to their oral mucosa. Survival rate of rats, weight changes, and food intakes were examined from day 0 to 18 after radiation. Histology study was performed from oral mucosa of rats at day 7 and 18 after radiation. RESULTS: rhEGF-treated groups (15 or 30 microgram/day) showed all survival rate 33%, whereas un-treated and vehicle-treated groups showed all survival rate 0% at the end of experiment. rhEGF-treated groups statistically had less weight loss compared to vehicle-treated group from day 2 to 7 after radiation. Food intake of rats with rhEGF treatment turned to increase at day 14 after radiation. At 7 day after radiation, un-treated and vehicle-treated groups showed severe pseudomembraneous or ulcerative oral mucositis. On the other hand, rhEGF-treated groups had no more than cellular swelling and degeneration of epidermal cells in oral mucosa of rats. CONCLUSION: These results suggest that rhEGF has significantly positive effects on radiation-induced oral mucositis in rats. rhEGF display a therapeutic potential on a clinical level.

BACKGROUND: Salvia miltiorrhiza (SM) has been used to treat inflammatory diseases including edema and arthritis; however, the anti-inflammatory mechanism of SM action remains unresolved. METHODS: The effects of an ethanol extract of SM (ESM) on pro-inflammatory cytokines such as TNF-alpha, IL-1beta, IL-6, and NO, on anti-inflammatory cytokines including IL-4, IL-10, TGF-beta, and IL-1Ra have been studied in an attempt to elucidate the anti-inflammatory mechanism in murine macrophages. RESULTS: ESM inhibited the production of pro-inflammatory cytokines via down-regulation of gene and protein expression whereas it increased the anti-inflammatory cytokines. Furthermore, ESM inhibited the expression of the chemokines, RANTES and CX3CL1, as well as of inflammatory mediators such as TLR-4 and 11beta-HSD1. CONCLUSION: These results indicated that the regulatory effects of ESM may be mediated though the suppression of pro-inflammatory cytokines as well as the induction of anti-inflammatory cytokines. Consequently, we speculate that ESM has therapeutic potential for inflammation-associated disorders.

BACKGROUND: Chronic low grade inflammation is closely linked to type II diabetes, obesity, and atherosclerosis. Macrophages play a key role in the regulation of pro- or anti-inflammatory actions at the lesion sites of disease. Components of cordyceps militaris, cordycepin and adenosine, have been used for the modulation of inflammatory diseases. The effects of cordycepin in the modulation of macrophages have yet to be elucidated. We investigated the effects of cordycepin and adenosine on the morphological changes of macrophages under the inflammatory condition of LPS and an anti-inflammatory condition involving high concentrations of adenosine. METHODS: We confirmed the mRNA levels of the M1/M2 cytokine genes through RT-PCR and morphological change. RESULTS: LPS-activated macrophages returned to their inactivated original shape, i.e., they looked like naive macrophages, through the treatment with high concentrations of cordycepin (40 microgram/ml). LPS and adenosine activated macrophages also returned to their original inactivated shapes after cordycepin treatment; however, at relatively higher levels of cordycepin than adenosine. This change did not occur with relatively low concentrations of cordycepin. Adenosine down-regulated the gene expression of M1 cytokines (IL-1beta, TNF-alpha) and chemokines (CX3CR1, RANTES), as well as cordycepin. Additionally, M2 cytokines (IL-10, IL-1ra, TGF-beta) were up-regulated by both cordycepin and adenosine. CONCLUSION: Based on these observations, both cordycepin and adenosine regulated the phenotypic switch on macrophages and suggested that cordycepin and adenosine may potentially be used as immunomodulatory agents in the treatment of inflammatory disease.

Porcine epidemic diarrhea virus (PEDV) strains responsible for recent outbreaks in the United States have been occurring in Mainland Korea since late 2013. Over the past 10 years, PEDV outbreaks have not been reported on Jeju Island. However, in late March of 2014, PEDV re-emerged on Jeju Island and was found to be genetically identical to PEDV strains currently circulating in Mainland Korea. The present study was conducted to provide a better understanding of the epidemiology of PEDV and more effective preventive measures against PED.

Primary extranodal B cell lymphoma of mucosa- associated lymphoid tissue (MALT) can develop in diverse anatomic locations such as the stomach, salivary gland, thyroid, lung, and breast. Its distribution in the GI tract is as follows: 50~60% in the stomach, 20~30% in the small intestine and ileocecal area and 10% in the colorectal area. Although autoimmune and infectious diseases are known as the main etiologies, H. pylori infection has been clearly shown to play a causative role in lymphomagenesis, especially in the stomach. H. pylori eradication therapy only can induce disease remission nearly in 80% of the cases of gastric MALT lymphoma. However, there is lack of evidence for the extragastric area. In this case, a 71-year-old woman with low abdominal pain was diagnosed as having a rectal MALT lymphoma that was noted as a solitary rectal mass in a colonoscopic examination. Remission induction was commenced by H. pylori eradication and radiation therapy.
