Abstract

The first hybrid mice ('shiverer*mld' mice) produced by intercrossing the homozygotes of the shiverer (BALB/c strain) and mld (MDB/Dt strain) were used for investigating the fine structure of the myelin lamellae, immunoreactive pattern for myelin basic proteins (MBP) and Golgi impregnated images of oligodendrocytes, with special reference to the influence of aging. All of the hybrid mice had an intermediate coat color between the white of the shiverer and black-brown of the mld, and revealed the same neurological symptoms, intention tremor, ataxic behavior, etc., as those of the shiverer and mld. The central myelin lamellae of the 'shiverer*mld' mouse exhibited the similar characteristics to the shiverer type rather than the mld type from the standpoint of the infrequent occurrence of major dense lines, although they did display a tendency to increase major dense lines with aging like the mld. Observation of the immunohistochemical preparations for MBP showed that immunopositive myelin sheaths were present in the white matter, although they were far more infrequent than those of the mld mutant, probably reflecting the amount of major dense lines. Thus, in the CNS of the 'shiverer*mld' mouse, the MBP-synthesis was possibly much more disturbed than in the mld mutant, or at least, revealed an intermediate pattern between the mld and shiverer.
