[Effects of normobaric oxygen on rat hepatocytes].
Exposure of adult rats to oxygen (100%) during 55 hrs decreases their sleeping time induced by pentobarbital and doesn't modify their paralysis time provoked by zoxazolamine. At 48 and 55 hrs, the hepatic cytochrome P-450 decreases significantly. Morphological study showed tissular changes suggestive of hepatic hemodynamic perturbations, which are probably responsible for the functional modifications.
