Neuroprotective effect of vitamin D3 toward apoptosis induced by ethanol in CA1 pyramidal cells of rat hippocampus

---

As an antioxidant. Vitamin D3 can protect neurons from damage caused by oxidative stress. Ethanol is known to have neurotoxic effects by inducing an increase in oxidative stress. One of the brain regions that is most sensitive to neurotoxic effects induced by ethanol is hippocampus, especially its CA1 region. This study was aimed to determine the neuroprotective effects of vitamin D3 in preventing the apoptosis in CA1 hippocampal pyramidal cells induced by ethanol. Fifteen male Wistar rats (Rattus norveqicusi) were randomly divided into three groups. The control group was given daily normal saline solution intraperitoneally. The ethanol group was given 20% ethanol solution at a dose of 3 g/kg BW/day intraperitoneally. The vitamin D3 group was given vitamin D3 1µg/kg BW/day in 20% ethanol solution at a dose of 3 g/kg BW/day intraperitoneally. After 30 days, the rats were sacrificed, their brains were perfused with PBS followed by fixative and the hippocampus was dissected for histological preparations. Immunohistochemical staining for caspase was performed. Percentage of apoptotic CA 1 hippocampal pyramidal cells was calculated. The results showed there was no significant difference (p> 0.05) on the total number of pyramidal cells between the control group (20.52 ± 1.31), the ethanol group (19.02 ± 1.60), and the vitamin D3 group (21. 06 ± 0.70) per field of view. However there was a significant increase (p < 0.05) in the percentage of apoptotic CA1 hippocampal pyramidal cells in in the ethanol group (16.09 ± 0.67%) compared to the control group (10.60 ± 0.95%). Vitamin D3 significantly (p
