Figure 1From: Berberine chloride can ameliorate the spatial memory impairment and increase the expression of interleukin-1beta and inducible nitric oxide synthase in the rat model of Alzheimer's diseaseEffect of berberine chloride on the impairment of spatial memory induced by Aβ(1–40) injection. (A) Escape latencies per group of four trials tested in a morris water maze over 7 days. (B) The number of crossings over a position where a platform had been was measured for 120 s at seventh days after the last acquisition test. Values represent the means ± SD of 6 rats. * P < 0.01 when compared with the normal group. # P < 0.01 when compared with the Aβ(1–40) injection group.Back to article page
