H2HUBB TAKEAWAY
The researchers found that saturated hydrogen saline treatment efficiently decreased the activation of ERK and JNK, while promoting the activation of p38 (P<0.05 compared with LPS), suggesting the involvement of MAPK cascades in saturated hydrogen saline-mediated liver protection. These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.
What the Findings Mean
H2HUBB reviewed how molecular hydrogen affected the outcomes measured in rats. The researchers found that saturated hydrogen saline treatment efficiently decreased the activation of ERK and JNK, while promoting the activation of p38 (P<0.05 compared with LPS), suggesting the involvement of MAPK cascades in saturated hydrogen saline-mediated liver protection.
What the Researchers Studied
The researchers studied rats. The study used a preclinical animal experiment. The comparison condition was control condition or baseline measurements.
What Effects Did Molecular Hydrogen Have?
Received January 22, 2013 Accepted April 25, 2013 Summary To determine the effect of saturated hydrogen saline on lipopolysaccharide (LPS)-induced acute liver dysfunction, rats were divided into control, LPS, and LPS plus saturated hydrogen saline (LPS+H₂) groups. In the LPS+H₂ group, rats were given 8 ml/kg saturated hydrogen saline by caudal vein injection 20 min prior to LPS treatment, and every 1 h for a continuous 6 h after LPS administration. Twenty rats in the LPS group, and 20 rats in the LPS+H₂ group were maintained for 72 h after the final injection to determine animal survival, while the other rats were anesthetized with an intraperitoneal injection of 20 % urethane (w/v; 3.75 ml/kg body weight) 6 h after the final injection. The researchers found that saturated hydrogen saline treatment efficiently decreased the activation of ERK and JNK, while promoting the activation of p38 (P<0.05 compared with LPS), suggesting the involvement of MAPK cascades in saturated hydrogen saline-mediated liver protection. Mitogen-activated protein kinase (MAPK), NF-kappaB, and Smac may contribute to saturated hydrogen saline-mediated liver protection. Saturated hydrogen saline reduced oxidative stress in livers induced by LPS challenge Since MDA and MPO ar e biomarkers for oxidative stress, the researchers examined MDA and MPO levels in liver tissues in rats after different treatments.
Why These Findings Matter
These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.
How Strong Is This Evidence?
This is preclinical animal evidence from a preclinical animal experiment. It is most informative for the disease model, mechanisms, biomarkers, and outcomes directly measured in the study.
