Jennifer Matthews: Living the simple life isn't so simple for June Macho. June Macho: I'm the type that has to be doing something all the time. I'm a Gemini, and Gemini's are like that, you know. Jennifer Matthews: For most of her life, this Gemini worked two jobs. But a stroke forced her to take it easy. She doesn't like it, but she's happy about one thing. June Macho: I'm glad to be alive. That's the one thing you know. Jennifer Matthews: June has good reason to feel lucky. Doctors were able to treat her. Dr. Anthony Furlan: 95 percent of stroke patients receive no specific treatment. Jennifer Matthews: Doctor Furlan says the only approved treatment must be given within three hours of when a stroke happens. Now, he's studying an experimental drug -- called Desmoteplase -- that could widen that window to nine hours. Dr. Anthony Furlan: We could potentially triple the number of patients we're treating because of that. Jennifer Matthews: Desmoteplase comes from a protein found in the saliva of vampire bats. It may sound a little spooky, but that protein prevents blood from clotting. Dr. Anthony Furlan: This could change the whole treatment paradigm for stroke. We might go from treating 5 percent of patients to 25, even a third of stroke patients. That's a huge jump. Jennifer Matthews: Patients who were injected with the drug were three-times more likely to have their arteries re-open, and about 60 percent improved after 90 days. June's car sits in the garage ... unused. She's not going anywhere soon, but she's glad she can at least get up and walk. She thanks Desmoteplase for that. June Macho: If I didn't get it, I wouldn't be here. That's the way I feel, you know. Jennifer Matthews: June plans on being here for a long time, and even wants to go back to work ... one day. This is Jennifer Matthews reporting.
