1.Research on some effects and acute toxicity of Kim Ngan Hoa
Journal of Medical Research 2002;18(2):40-46
There different extract solutions of Kim Ngan Hoa were used in this study. The experimental results showed that: Kim Ngan Hoa has analgesic effect on two experimental models, hotplate and writing test on mice. Beside of analgesic effect, it has significantly acute antiinflammatory effect on rats. The effects of flavonoid and the alcoholic extract are potent than the effects of the water extract. Three extract solutions from Kim Ngan Hoa have also inhibitory effect in vitro the developing of three bacteria: Staphylococcus aureus, E. coli and Pseudomonas aeruginosa. Three preparations from Kim Ngan Hoa have very low acute toxicity

Background:\r\n', u'There are two virus known as Nam Dinh Virus, and Colti group B be found in Viet Nam. These viruses have appeared in the South, the Middle and the Highland. They haven\u2019t been reported in the Southern provinces and Can Thoas well. \r\n', u'Objectives: \r\n', u'To identify the circulation of Nam Dinh virus strain, and coltivirus group B strain in Can Tho, Southern Viet Nam, and their existence in nature.\r\n', u'Subjects and method: \r\n', u'Thirty-four mosquito samples (7, 453 individual mosquitoes) from Culex quinque faciatus and Culex pseudovishnui were collected in Can Tho provice, southern Vietnam 2005.\r\n', u'Isolatingviruses on Aedes albopictuc clone C6/36, Vero cells, and using PT- PCR and ELISA Sandwich for identification. \r\n', u'Results:\r\n', u'2 Nam Dinh virus strains, 2 coltivirus group B strains and 1 flavivirus strain (insect flavivirus) were isolated from Culex quinque faciatus, and no virus was isolated from Culex pseudovishnui.\r\n', u'Conclusion: \r\n', u'The identification of the transmission of Nam dinh Virus, and coltivirus group B in Can Tho province by isolating virus from Culex quinque faciatus has shown the evidence for natural vertical transmission of these viruses.\r\n', u'
