08 March 2016 Current Affairs: Indian scientist developed herbal medicine for Dengue. For 50 per cent of the global population estimated to be at risk from the disease.The project was undertaken jointly by the Department of Biotechnology (DBT), under the Ministry of Science and Technology, the International Centre for Genetic Engineering and Biotechnology (IGCEB) and Ranbaxy Research Laboratory (now owned by Sun Pharma), and employed Ayurveda in devising the drug."Using the knowledge of traditional Indian medicine -- Ayurveda -- we developed a systematic bioassay-guided screening approach to explore the indigenous herbal bio- resource to identify plants with pan-DENV (dengue virus) inhibitory activity," said Navin Khanna, senior scientist at ICGEB and the group leader of the project.Dengue, a mosquito-borne viral disease, poses a significant global public health risk. In tropical countries such as India, where periodic dengue outbreaks can be correlated to the high prevalence of the mosquito vector circulation of all four dengue viruses (DENVs) and the high population density, a drug for dengue is being increasingly recognised as an unmet public health need.India represents 50 per cent of the global population estimated to be at risk of dengue. Severe dengue, which is potentially fatal, correlates with very high virus load, reduction in platelet counts and haemorrhage.
