Effects on NaHS on the expression of Fas and FasL. The black arrows indicate cells positively stained for Fas and FasL. There was no difference between the sham (A) and sham+NaHS (B) groups and HS elevated the expression of Fas (C). Administration of NaHS reduced the expression of Fas (D). Similarly, the expression of FasL also was low in the sham (E) and sham+NaHS (F), and increased in the HS group (G), and NaHS treatment significantly reduced the expression of FasL (H).
