Effect of molecular hydrogen on uterine inflammation during preterm labour

Year Published: 2018

Intrauterine inflammation causes preterm birth and is associated with complications in preterm neonates. Thus, strategies aimed at suppressing inflammation are expected to be effective for reducing the risk of preterm birth and associated complications. Our previous studies demonstrated that molecular hydrogen (H2), an anti-inflammatory agent, prevented inflammation-induced impairment in foetal ...

Hydrogen inhibits cytotrophoblast cells apoptosis in hypertensive disorders complicating pregnancy

Year Published: 2016

Hypertensive disorders complicating pregnancy (HDCP) is one of the most serious medical disorders during pregnancy. Hydrogen is a therapeutic antioxidant and used to treat HDCP effectively. However, the molecular mechanism about the effect of hydrogen on HDCP still remains unclear. In this study, we found ROS content in HDCP group was significantly higher than that in the control and was reduced ...

Neuroprotective potential of molecular hydrogen against perinatal brain injury via suppression of ...

Year Published: 2016

Exposure to inflammation in utero is related to perinatal brain injury, which is itself associated with high rates of long-term morbidity and mortality in children. Novel therapeutic interventions during the perinatal period are required to prevent inflammation, but its pathogenesis is incompletely understood. Activated microglia are known to play a central role in brain injury by producing a ...

Effects of vitamin C, vitamin E, and molecular hydrogen on the placental function in trophoblast ...

Year Published: 2015

Aim: This study aimed to investigate the effects of three different antioxidants, namely vitamin C, vitamin E, and molecular hydrogen, on cytotrophoblasts in vitro. Methods: Two trophoblast cell lines, JAR and JEG-3, were exposed to different concentrations of vitamin C (0, 25, 50, 100, 500, 1,000, 5,000 μmol/L), vitamin E (0, 25, 50, 100, 500, 1,000, 5,000 μmol/L), and molecular hydrogen (0, ...

Maternal inflammation is associated with spontaneous preterm birth and respiratory impairment among premature infants. Recently, molecular hydrogen (H2) has been reported to have a suppressive effect on oxidative stress and inflammation. The aim of this study was to evaluate the effects of H2 on fetal lung injury caused by maternal inflammation. Cell viability and the production of interleukin-6 ...
