National Academy of Agricultural Science and eight province Agricultural Research & Extension Services investigated the occurring area of herbicide resistant weeds in paddy field of Korea. In order to estimate the occurring areas of herbicide resistant weeds, we collected paddy soils randomly from 3,200 sites in 2011 and 2012, and treated 30 kg ha-1 of pyrazosulfuron-ethyl+pyriminobac-methyl GR to the paddy soil. 176,870 ha, approximately 22.1% of cultivated area excluding organic and eco-friendly cultivated area, was estimated to be infested by SUherbicide resistant paddy field weeds. Several species of resistant weeds were occurred at Jeonranam-do with 44.3%, followed by 30.5% at Chungchungnam-do, 27.8% at Chungchungbuk-do, and 24.5% at Jeonrabuk-do, respectively. Monochoria vaginalis showed the highest distribution with 57,018 ha, 32.2% followed by Scirpus juncoides, and Lindernia procumbens, respectively.
The purpose of this study was to systematically review the measurement tools that are used to assess the pain of intensive care unit (ICU) patients. Method : In this systematic review, the studies published between 2009 and 2018 were selected based on the PRISMA flow chart. Data sources included MEDLINE, EMBASE, CINAHL, and Cochran. We assessed the quality of pain assessment tools reported in individual studies using Terwee et al.'s the Quality Criteria for Measurement Properties. Results : We reviewed 67 studies and 12 pain assessment tools that included two self-reported, seven observational, and three multifaced tools with observations and physiological indicators. The most frequently used tool was the Critical Care Pain Observation Tool. The Multidimensional Observational Pain Assessment Tool was rated the highest quality. Nine of the ten tools that included observations reported content validity, four reported construct validity and nine reported correlation coefficient. Conclusion : It was found that observational tools are appropriate for assessing pain in ICU patients with limited communication skills. To increase the validity and reliability of pain assessment in ICU patients, further research on the physiological indicators of pain is needed.
Purpose: Ulcerative colitis is a common inflammatory bowel disease. Prolonged colitis can be a risk factor for the development of colorectal cancer. Mulberry twig (MT, Sangzhi), a dry branch of Morus alba L., which is widely distributed throughout East Asia, has been shown to have anti-inflammatory activities in the cells. However, the effects of MT extracts on colitis in in vivo are limited. Therefore, in this study, we investigated the anti-inflammatory effects of MT extracts in the dextran sulfate sodium (DSS)-induced mouse colitis model. Methods: Six week-old, male ICR mice were divided into 3 groups: Control (n = 5), DSS (n = 7), and DSS+MT (n = 7) groups. Mice in the DSS and DSS+MT groups were administrated 3% DSS in drinking water for 5 days to induce colitis. At the same time, water extracts of MT (5 g/kg body weight/day) were orally administered to mice in the DSS+MT groups for 5 days. Results: The MT extracts significantly reduced the clinical and pathological characteristics of colitis. Disease activity index, mucosal thickness, and colonocyte proliferation were significantly reduced in the DSS+MT group compared with the DSS group. Furthermore, MT administration reduced the levels of plasma TNF-α, IL-6, and the colonic myeloperoxidase activity as well as mRNA expression of TNF-α, IL-6, Cox-2, and iNOS. Conclusion: Taken together, these results suggest that MT water extracts have potent anti-colitis activities in the mouse colitis model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
