Nine cattle among 18 in a native Korean herd died or were euthanized within 3 days. The affected cattle showed cowshed. The pigs and dogs had been fed leftover food originating from nearby restaurants, and the cattle could presumably reach the contaminated food in the pig troughs. Necropsy revealed a few chicken bones and red pepper pieces as well as large amounts of grain and rice straw hay mixed in the rumen. Botulism type D was isolated in the ruminal contents of one of the cattle. We speculated that the outbreak was associated with the cattle incidentally eating presumably contaminated leftover food from the pig trough.

Objectives: The objectives of this study were to evaluate the effect of smoking on utilization of and expenses in ambulatory dental care. Methods: The subjects of this study were 5,751 men aged over 20 years selected from the Korea Health Panel data collected during 2010-2012. Pack-years of smoking were calculated based on the survey data. Dental utilization was defined as dental outpatient clinic use least once in three years. The expenses in ambulatory dental care were summed to determine total dental health care spending for three years. To detect the effect of smoking, we used multiple logistic regression analysis for dental utilization and multiple linear regression for expenses in ambulatory dental care after changing log. Results: The pack-years had a significant effect on dental utilization and expenses in participants aged 40-59 years. After controlling for income level, bedtime brushing, and the presence of chronic disease, dental care utilization rates in the over 10 to less than 25 pack-year and the over 25 pack-year groups were about 1.4 (OR=1.37, (P =0.007)) and 1.6 times (OR=1.59, (P =0.001)) those in the 0 pack-year group. In comparison with the 0 pack-year group, the over 10 to less than 25 pack-year group spent 50,000 won more over dental expenses, while the corresponding number for the over 25 pack-year group was about 100,000 won. Thus, the ambulatory dental care expenses increased with the packyears of smoking. Conclusions: Smoking significantly influenced the utilization and expense in ambulatory dental care in men aged 40-59 years.

Hepatoprotective Effect of Uncaria rhynchophylla on Thioacetamide-Induced Liver Fibrosis Model

Liver fibrosis is a wound-healing response to chronic liver injury, which is caused by the continuous and excess deposition of extracellular matrix (ECM). The aim of this study is to investigate whether Uncaria rhynchophylla water extract (UR) can ameliorate thioacetamide (TAA)-induced liver fibrosis. The liver fibrosis model was induced on C57BL/6 mice by intraperitoneal injection with TAA three times a week for 8 weeks. UR (200 mg/kg) or silymarin (50 mg/kg) was administered orally daily for 8 weeks. Biochemical analyses including AST, ALT, MPO, and Ammonia levels were measured in serum. In the mice liver tissues, western blot and histological staining were analyzed. As a result, UR dramatically reduced the levels in serum AST, ALT, MPO, and Ammonia levels. UR treatment regulated NADPH oxidase factors expression, and antioxidant enzymes except for GPx-1/2 were significantly increased via Nrf2 activation. Furthermore, pro-inflammatory mediators, such as COX-2 and iNOS were markedly suppressed through the inhibition of NF-κB activation. Expressions of ECM-related protein including α-SMA and Collagen I were noticeably decreased. The additional histological evaluation confirmed that hepatocyte damage and collagenous fiber accumulation were attenuated. Taken together, these data suggest that UR possessed hepatoprotective effects in TAA-induced liver fibrosis via the NF-κB inactivation and Nrf2 activation. Therefore, UR may act as a potential therapeutic drug against liver fibrosis.
Change of 2-back Task Performance due to Highly Concentrated Oxygen Administration: ADHD in Children

Objective: This study investigated changes in 2-back task performance of Attention Deficit Hyperactivity Disorder (ADHD) children when the concentration of oxygen administration was varied (21% or 92%). Background: The highly concentrated oxygen induced improvement of cognitive abilities via increasing the percentage of correct answers or reducing response time for nomal young adults. Method: It recruited totally 13 children (12.9±1.3 years) with ADHD. The experiment consisted of 2-back task performed under two conditions (21% and 92%). Each run consisted of three phases: adaptation of oxygen (1 min.), control (2 min.), and 2-bak task (2 min.). Results: There was a significant decrease in reaction time in the presence of 92% oxygen compared with the 21% oxygen condition. Conclusion: This result supports the hypothesis that hyperoxic air increase oxygen saturation level in the blood, lead to more available oxygen to the brain, thus increase the ability of cognitive processing of ADHD children. Application: It expected improvement of life quality for the cognitive impairment persons.
