[Protective effect of hyperbaric hypoxygenation for paraquat poisoning in the rat]. / Effet protecteur de l'hypoxygénation hyperbarique au cours de l'intoxication par le paraquat, chez le rat.

The effect to paraquat in normobaric conditions and hyperbaric conditions with either a normal or low (10%) oxygen percentage was investigated in rats. Results showed that hyperbaric conditions increased the toxic effect of paraquat on the lung. By contrast, in hypoxic-hyperbaric conditions, the toxic effect of paraquat was decreased either clinically or macro-/microscopically, and lung injury was reduced.
