Abstract:
Hydrogen is considered to be a novel antioxidant as it inhibits inflammation, removes oxygen-derived free radicals and reduces oxidative damage. This study investigated the effects of hydrogen-rich saline on plasma interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), superoxide dismutase (SOD) and malondialdehyde (MDA) in rats with uncontrolled hemorrhagic shock (UHS). The UHS model was induced by arterial bleeding and tail amputation. The rats were randomly divided into: Group A (sham-operated group), Group B [shock + intravenously (IV) injected saline], Group C (shock + IV-injected hydrogen-rich saline), Group D [shock + intraperitoneally (IP) injected saline] and Group E (shock + IP-injected hydrogen-rich saline). The survival rate 24 h after successful resuscitation was calculated. The mean arterial pressure and heart rate were recorded at 0, 30, 90 and 210 min. The plasma levels of IL-6, TNF-α, SOD and MDA were measured at 0, 90 and 210 min. The survival rate of each group was 100% and the hemodynamics among the experimental groups were not significantly different. At 90 and 210 min, the levels of IL-6, TNF-α and MDA in Groups C and E were lower than those of Groups B and D, while the SOD levels were higher than those of Groups B and D (P<0.01). At 90 min, the levels of IL-6, TNF-α and MDA in Groups B and C were lower than those of Groups D and E, respectively (P<0.01). Hydrogen-rich saline has anti-inflammatory and anti-oxidative effects in UHS. In conclusion, the results showed that itravenous injection of hydrogen-rich saline is more effective than intraperitonal injection.

Purpose Hydrogen gas (H2) inhalation improved the survival rate of hemorrhagic shock. However, its mechanisms are unknown. We hypothesized that H2 protected the endothelial glycocalyx during hemorrhagic shock and prolonged survival time. Methods 83 Sprague–Dawley rats were anesthetized with isoflurane….
Background: Hydrogen gas (H2) inhalation during hemorrhage stabilizes post-resuscitation hemodynamics, improving short-term survival in a rat hemorrhagic shock and resuscitation (HS/R) model. However, the underlying molecular mechanism of H2 in HS/R is unclear. Endothelial glycocalyx (EG) damage causes hemodynamic failure…
