98 and July 2001, 37 had blood glucose (sugar) levels greater than 8 millimoles per liter (mmol/L) at admission (group A) and 76 had glucose levels lower than 8mmol/L (group B). Researchers measured improvement on the National Institutes of Health Stroke Scale (NIHSS) at 24 hours and three months, and three-month mortality. Eighteen patients in group A and 42 patients in group B improved their NIHSS scores by more than four points at 24 hours. At three months, the rate of greater-than-four-point improvement was higher in group B (79 percent compared to 54 percent). At three months, 36 percent of group A patients and 8 percent of group B patients had died. Researchers conclude that individuals who have hyperglycemia before receiving tPA have a greater risk of death, and those who survive recover less compared to patients with normal glucose.

5:30 p.m. #P197 Viagra has potent effect on stroke recovery in rats. Researchers induced ischemic stroke in rats, then investigated the effects of sildenafil citrate commonly known as Viagra on the production of new brain cells and on functional recovery. Viagra was administered orally to rats for six days after stroke. At 28 days, the number of new brain cells was significantly higher in rats treated with Viagra. Rats that received two milligrams (mg) of Viagra showed 237.27 millimeters squared (mm2 ) of new cells; those treated with five mg of Viagra had 541.02 mm2 of new cells, while untreated rats had only 177.94 mm2. To measure the severity of brain impairment, the rats performance on sensory, motor and agility tests were measured at two and 28 days after stroke. The animals speed at removing adhesive from their feet was tested as well as their adeptness at walking on a grated pathway. Viagra-treated rats showed significantl
