  • Look Inside

The effect of S-adenosyl-L-methionine sulfate tosylate (FO-1561) on survival time in various brain damage models (cerebral anoxia or ischemia) was studied.

1) In KCN-induced or normobaric anoxia of ddY mice, FO-1561 (30-100 mg/kg as amount of S-adenosyl-L-methionine) administered intravenous-ly 15-30 min prior to the treatment showed significant increase of survival time dose-de-pendently.

2) In asphyxic anoxia of Wistar rats, FO-1561 (100 mg/kg) administered intravenously 15 min prior to the treatment (cessation of artificial re-spiration) delayed the time until the disappearance of electrocorticogram.

3) In cerebral ischemia of Mongolian gerbils, FO-1561 (50 mg/kg) injected five times at 1 hr interval intraperitoneally 3 hr after the unilateral ligation of common carotid arteries showed significant increase of survival time.

These results suggested that FO-1561 may be effective in ameliorating cerebral anoxic or ischemic damage, without observing any side effects like sedation and motor depression which pentobar-bital showed with the effective doses in these damage models.
