[Interrelation of delta-aminolevulinic acid and brain myelin proteins as affected by benzene and lead].
An experimental model of subacute lead and benzene intoxication was induced in rabbits. It increased significantly delta-aminolevulinic acid (14C-ALA) incorporation into CNS myelin. ALA stably fixes on myelin proteins, especially Wolfgram proteins. In spite of this about one half of ALA incorporated into myelin linked with its basic proteins. Lead and benzene intoxication cause changes in the proportion of the basic fractions of myelin proteins. The amount of basic proteins increases, while the amount of proteolipid and Wolfgram proteins decreases. Lead and especially benzene intoxication decreases exogenous ALA insertion into basic proteins and proteolipid proteins, with ALA fixation on Wolfgram proteins remaining unchanged.
