Objective: Investigate Vitamin D-3 (VD3) effect on the Acetylcholinesterase (AChE), oxidative damage and behavioral tests in animals subjected to Intracerebroventicular injection of Streptozotocin (ICV-STZ) simulating a Sporadic Dementia of Alzheimer's Type (SDAT) and treated with VD3 (21 days). Methods: Animals were divided into eight groups: Vehicle, VD12.5 mu g/kg, VD42 mu g/kg, VD125 mu g/kg, STZ, STZ+VD12.5 mu g/kg, STZ+VD42 mu g/kg, STZ+VD125 mu g/kg. Results: VD3 prevented the increase in AChE in groups of VD42 mu g/kg and VD125 mu g/kg; in AChE of synaptossomes and TBARS levels prevented the increase in group VD125 mu g/kg; in ROS levels there was not a significant difference; for the Carbonyl Content all doses prevented the increase. Total Thiols prevent the decrease in VD42 mu g/kg and VD125 mu g/kg, and Reduced Glutathione prevented the decrease in VD125 mu g/kg, Oxidized Glutathione prevented the increase in VD125 mu g/kg. In relation to behavioral tests, the VD3 prevented the increase in time to find (days 2 and 3), in the time to find the platform (day 3) and in time spent in the quadrant (day 2). However, in relation to crossings there was not difference in groups. These results indicated the therapeutic effect of the VD3 in model of STZ in rats.
