ACUTE TOXICITY STUDIES ON ETHANOL, PROPANOL, AND BUTANOL

Abstract
Three series of 10 dogs each were used to study the effects of intravenously administered ethanol, propanol-1, and butanol-1. In normothermic dogs, with supported respiration and nitrous oxide anaesthesia (after induction), the mean lethal doses for ethanol, propanol-1, and butanol-1 were 4.90, 2.42, and 1.26 gAg respectively. At a constant infusin rate, the blood alcohol levels increased almost linearly with time. Relationships between ethanol, propanol-1, and butanol-1 blood levels and blood pressure, pulse, and electrocardiogram were established. Two minutes cardiac standstill occurred at the following blood levels: ehtanol, 1499 mg/100 ml; propanol-1, 713 mg/100 ml; butanol-1, 279 mg/100 ml.
