Abstract:
:To study the pathophysiology of olivopontocerebellar atrophy (OPCA), we destroyed inferior olive nuclei of male Wistar rats using 3-acetyl pyridine (3-AP) + harmaline + niacinamide. These rats showed a sluggish and ataxic gait. To elucidate the relationship between thyrotropin releasing hormone (TRH) in the Purkinje cell of cerebellum and the inferior olive nucleus, we investigated the concentrations of TRH in the cerebellar cortex, nuclei, and medulla oblongata including the inferior olive nuclei using radioimmunoassay method as well as TRH receptor in the Purkinje cells of cerebellum using immunohistochemical method. All statistical comparisons were done using non-parametric tests (Mann-Whitney U-test). We found that two weeks after the treatment, TRH concentrations in the cerebellar cortex as well as nuclei were significantly lower than in the controls but no significant difference in the medulla oblongata was observed between 3-AP treated rats and controls. Moreover, four weeks after the treatment, TRH-receptor positive Purkinje cell counts were significantly fewer than in the controls. These results suggest that TRH in the Purkinje cell of cerebellum may play a role in the ataxic gait observed in the rats whose inferior olive were destroyed.
