| Research Abstract |
Hydrogen sulfide (H2S), well-known for one of endogenous gas molecules, is reported to possess potency of anti-inflammation, radical scavenging effect,and anti-apoptotic effect, etc. We have investigate the neuroprotective effect of inhaled H2S (80ppm x 5 hrs) against delayed onset paraplegia after spinal cord ischemia in mice. As a result from our experiments, mice treated with inhaled hydrogen sulfide showed significant better neurological outcome at 72 hrs of reperfusion with preserving the number of normal neurons in spinal ventral horn. Additionally, inhaled H2S suppressed the expression of cleaved caspase3 in the spinal ventral horn significantly comparing with control group. According to the present data, it is suggested that inhaled H2S potentially protect spinal ventral neurons after spinal cord ischemia, and this protective effect might be associated with its anti-apoptotic effect.
