GB decreased the [Ca2+]i of cultured neurons under hypoxic conditions. (A) Representative images showing fura-4 fluorescence (green; used as a measure of [Ca2+]i) in cultured primary hippocampal neurons from each of the four experimental groups. Scale bar: 10 μm. (B) Quantification of the fluorescence intensity in the control, GB, hypoxia and hypoxia+GB groups. Data are expressed as the mean ± SEM (n = 8). **P < 0.01 vs. control group; #P < 0.05 vs. hypoxia group (Student's t-test).
