| 1 | Effect of Punica granatum peel extract on learning and memory in rats显示文摘Objective:To evaluate potential memory enhancing effect of Punica granatum peel extract on rats.Methods:Healthy adult male albino rats of Wistar strain were used.Each group of 6 rats were administered either distilled water or 50 mg/kg of extract or 100 mg/kg of extract for 15 days and subjected to passive avoidance test or T-maze test.In the next phase rats were administered distilled water or 100 mg/kg of extract for 15 days and the rats were given injection diazepam before subjecting them to the tests.Results:The overall performance was better in test groups compared to control groups.Among the test groups,100 mg/kg rats performed better than 50 mg/kg.The effect on spatial learning parameters like mean number of alternations and mean percentage bias was more marked compared to retention testing parameters like latency. 100 mg/kg Punica extract treated group also improved performance of diazepam treated rats. Conclusions:There is a definite trend of memory improvement by Punica granatum peel with effects being more marked on spatial learning tendency and long term memory than on retention capacity. | Shalini Adiga Prabhav Trivedi Ravichandra V Debashree Deb Forum Mehta | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，9： | 3 |
| 2 | Knowledge,attitude and anxiety pertaining to basic life support and medical emergencies among dental interns in Mangalore City,India显示文摘BACKGROUND: This cross-sectional study aimed to assess the knowledge, attitude and anxiety pertaining to basic life support(BLS) and medical emergencies among interns in dental colleges of Mangalore city, Karnataka, India.METHODS: The study subjects comprised of interns who volunteered from the four dental colleges. The knowledge and attitude of interns were assessed using a 30-item questionnaire prepared based on the Basic Life Support Manual from American Heart Association and the anxiety of interns pertaining to BLS and medical emergencies were assessed using a State-Trait Anxiety Inventory(STAI) Questionnaire. Chi-square test was performed on SPSS 21.0(IBM Statistics, 2012) to determine statistically signifi cant differences(P<0.05) between assessed knowledge and anxiety.RESULTS: Out of 183 interns, 39.89% had below average knowledge. A total of 123(67.21%) reported unavailability of professional training. The majority(180, 98.36%) felt the urgent need of training in basic life support procedures. Assessment of stress showed a total of 27.1% participants to be above highstress level. Comparison of assessed knowledge and stress was found to be insignifi cant(P=0.983).CONCLUSION: There was an evident lack of knowledge pertaining to the management of medical emergencies among the interns. As oral health care providers moving out to the society, a focus should be placed on the training of dental interns with respect to Basic Life Support procedures. | Vinej Somaraj Rekha P Shenoy Ganesh Shenoy Panchmal Praveen S Jodalli Laxminarayan Sonde Ravichandra Karkal | 2017 | World Journal of Emergency Medicine2017，8，2： | 2 |
