Figures & data

Figure 1. Effect of SQGD and/or 5-FU treatment on G-CSF expression in serum. Mice were treated with SQGD and/or 5-FU and blood samples were collected at different timepoints for subsequent analysis. C, Control; S, SQGD-treated mice; 5-FU, 5-FU only-treated mice; S + 5FU, Mice pre-treated with SQGD 2 h before 5-FU treatment. All values shown are mean ± SD (n = 6 mice/treatment group for each timepoint). Values significantly different: $p < 0.05, SQGD versus control;*p < 0.05, 5-FU only versus control; **p < 0.05, SQGD + 5-FU versus 5-FU only.
