[Modification of the saccharide structures of orosomucoid in rats stimulated by treatment with phenobarbital].

The administration of phenobarbital (80 mg/kg body weight for 3 days) increased the plasma orosomucoid level with dramatic alterations in the relative proportions of heteroglycans. A crossed immunoaffinoelectrophoresis with Con A revealed an increase of strongly reactive fractions with a concomitant decrease of non and weakly reactive fractions.
