London: The saliva of vampire bats, which feed on blood, can save lives of stroke victims, new research shows.The saliva has a compound that can thin blood and dissolve clots in the brain.Currently, most types of strokes need clot-busting shots within four hours of the attack for effective treatment.But a drug derived from proteins in bats` saliva can have the same effect for up to nine hours.Researchers who carried out a previous smaller study said the drug was "the biggest breakthrough" in stroke treatment in two decades.The difference implies that drug Desmoteplase could be administered to stroke victims while asleep, the Telegraph reports.
