London: Applying an ointment to the snakebite site can buy 50 percent more time for victims to seek help, thereby boosting their chances of survival, according to a new study. When a snake bites you, large molecules of toxins get injected into tissues, as they are too big to break into blood vessels. So they get taken up by the lymphatic system, which in turn takes them into the blood vessels. To slow this journey, Dirk van Helden at the University of Newcastle at Callaghan, Australia, and colleagues applied nitric oxide cream - which stops the pumping of the lymphatic system - to mice injected with venom. The cream increased the time it took the venom to reach the blood supply from 65 to 96 minutes. This would buy bite victims around 50 per cent more time to seek treatment, says van Helden. ANI
