FIGURE 2.
Effect of vitamin D3 on memory impairment of mice according to the Morris water maze test (MWM) (n = 8). (a) Spatial learning in the MWM on day1 to 5. Average escape latency (s) was shown for the four training sessions in the maze. (b) Representative swimming path of mice in 120 s on day 6. (c) Times in the target quadrant (s) during probe testing on day 6. (d) The proportion of distance in the target quadrant (s) during probe testing. (e) The number of platform crossings. Data were means ± SE. * p < .05, ** p < .01 versus normal control rats. # p < .05, versus DM control rats. HVD, high‐dose vitamin D3 group; LVD, low‐dose vitamin D3 group; MVD, medium‐dose vitamin D3 group
