Effect of venoruton on hypoxic stress-induced neurotoxicity in mice and oxygen free radical generation by human neutrophils.

Venoruton offers a protection against hypoxic stress-induced neurotoxicity (convulsions and death) in mice. It also inhibits free radical generation, since it produces a concentration-dependent (5-160 micrograms/10(6) cells/ml) decrease of chemiluminescence response from human neutrophils. The maximum inhibition was observed at 140 micrograms/10(6) cells/ml. The in vivo protective effect against hypoxic stress-induced neurotoxicity has been correlated to the inhibitory action of venoruton on oxygen free radical generation.
