Vitamin D3 can act as an antioxidant that protects neurons against damage caused by oxidative stress. Neurotoxic effects that are mediated by increased oxidative stress can be induced by the ethanol. Cerebellum is one of the brain regions most sensitive to neurotoxic effects induced by the ethanol. The purpose of this study was to determine the neuroprotective effects of vitamin D3 to prevent the decrease in the number of cerebellar Purkinje cells to the neurotoxic effects induced by ethanol. Fifteen male Wistar rats (Rattus norvegicus) were randomly divided into three groups. The control group was given normal saline solution; the ethanol group was given 20% ethanol solution at a dose of 3 g/kg BW/ day; and the vitamin D3 group was given vitamin D3 1 ?g/kg BW/day in 20% ethanol solution at a dose of 3 g/kg BW/day, intraperitoneally. After 30 day treatment, the rats were perfused and the cerebellum was dissected for histological preparations. Histological staining with cresyl violet was performed to assess the number of cerebellar Purkinje cells by the method of fractionator. The results showed the number of cerebellar Purkinje cells in the ethanol group (744.552 ± 208.172,22) was less than the control group (957.240 ± 160.353,03) and vitamin D3 (983.448 ± 152.387,49), but statistically not significant difference (p>0.05) on the number of cerebellar Purkinje cells among the three groups. It can be concluded that vitamin D3 had not been proven for its neuroprotective effect to prevent the decrease in the number of cerebellar Purkinje cells caused by ethanol administration for 30 days.
