[Effects of neutral oil of Ligusticum sinense Oliv. on anoxia]

The neutral oil at 2.5 and 5.0g/kg P.O. can significantly decrease the oxygen consumption and prolong survival time for mice, increase the ability of tissues to tolerate anoxia and extend survival time under cerebral ischemic anoxia in mice. It can also inhibit the pituitrin-induced depression of S point in rats.
