BACKGROUND
H2S can also protect nerve cells. The objective of the study is to investigate the effects of hydrogen sulfide (H2S) on the expressions of brain-derived neurotrophic factor (BDNF) and its receptors, tyrosine protein kinase B (TrkB) and p75 neurotrophin receptor (p75NTR), in brain tissues of rats with cardiac arrest and cardiopulmonary resuscitation (CA/CPR) following the restoration of spontaneous circulation (ROSC).RESULTS
Survival rate of the three groups had significant difference (χ2 = 28.376, p = 0.000). The Intervention group had the highest survival rate (82.5%), while the Inhibition group had the lowest survival rate (62.5%). The mRNA and protein levels of BDNF and TrkB in the Intervention group were significantly higher compared to the Control group (p < 0.05); while the mRNA and protein levels of BDNF and TrkB in the Inhibition group was significantly lower than the Control group (p < 0.05) on days 1, 3, and 7. However, the mRNA and protein levels of p75NTR in the Intervention group were significantly lower than the Control group (p < 0.05); while the mRNA and protein levels of p75NTR in the Inhibition group were significantly higher than the Control group (p < 0.05) on days 1, 3, and 7.
