[Ultrastructural study of the remyelinating process following local ethidium bromide injection in the brainstem of dexamethasone-immunosuppressed rats].

Lymphocytes are present within ethidium-bromide (EB)-demyelinated lesions in the central nervous system (CNS) and the possibility of its participation in accidental immune-mediated responses to the detached myelin sheaths can not be ruled out. This study aimed to investigate the consequences of immunosuppression with dexamethasone in CNS repair after local EB injection. Adult Wistar rats received 10 microlitres of 0.
