In this study, the effects of GFS on the 5-HT system in the Sprague-Dawley （SD） rats with MI, depression, and MI ＋ depression were evaluated. Methods： A total of eighty SD rats were allocated to four groups： MI, depression, MI ＋ depression, and control groups （n = 20 in each group）. Each group included two subgroups （n = 10 in each subgroup）： Saline treatment subgroup and GFS treatment subgroup. The levels of 5-HT, 5-HT2AR, and serotonin transporter （SERT） were quantified in serum, platelet lysate, and brain tissue through the enzyme-linked immunosorbent assay method, respectively. Results： Compared with those in the saline treatment subgroups, the levels of 5-HT in serum and platelet lysate statistically significantly increased in the GFS treatment subgroups of MI, depression, and MI ＋ depression groups （serum： all P = 0.000; platelet lysate： P = 0.002, 0.000, 0.000, respectively）. However, the 5-HT levels in brain homogenate significantly decreased in the GFS treatment subgroups compared with those in the saline treatment subgroups in MI and depression groups （P = 0.025 and 0.044 respectively）, and no significant difference was observed between saline and GFS treatment subgroups in MI ＋ depression group （P = 0.663）. Compared with that in GFS treatment subgroup of control group, the 5-HT2AR levels in the platelet lysate significantly decreased in GFS treatment subgroups of MI, depression, and MI ＋ depression groups （all P = 0.000）. Compared to those in the saline treatment subgroups, the serum SERT levels significantly decreased in the GFS treatment subgroups in MI, depression, and MI ＋ depression groups （P = 0.009, 0.0展开更多
