Effect of exogenous hydrogen sulfide in the nucleus tractus solitarius on gastric motility in rats

Figure 1 Co-expression of cystathionine beta-synthase (green) and c-Fos (red) neurons in the nucleus tractus solitarius at different times of restraint water-immersion stress. A: Expression of cystathionine beta-synthase (CBS) and c-Fos in restraint water-immersion stress (RWIS) at 0 h; B: Expressions of CBS and c-Fos in RWIS at 1 h; C: Expression of CBS and c-Fos in RWIS at 3 h; D: Quantification of neurons co-expressing CBS and c-Fos in the nucleus tractus solitarius (n = 6). ^aP < 0.01 vs RWIS 0 h group. NTS: Nucleus tractus solitarius; RWIS: Restraint water-immersion stress; CBS: Cystathionine beta-synthase.
