Cromolyn inhibited surgery-induced MC degranulation in the hippocampus. a Immunostaining was used to detect mast cell tryptase in area CA1 of the hippocampus. Scale bar 50 μm. b Mast cells were stained with toluidine blue (TB) in area CA1 of the hippocampus. Scale bar 50 μm. c Quantification of Tryptase-positive cells in area CA1 of the hippocampus. d Quantification of mast cells stained with TB. ^* P < 0.05, ^** P < 0.01 vs. control group. ^# P < 0.05, ^## P < 0.01 vs. surgery group. Data are presented as the mean ± SD (n = 6)
