Hydrogen in lung transplantation

In Animal studies, Lung by CHESS

Molecular hydrogen (H2) has protective effects against ischemia-reperfusion injury in various organs. Because they are easier to transport and safer to use than inhaled H2, H2-rich solutions are suitable for organ preservation. In this study, we examined the protective effects of an H2-rich solution for lung preservation in a canine left lung transplantation (LTx) model. Ten beagles underwent orthotopic left …

Hydrogen-rich solution attenuates coagulation disorders and inflammation

In Animal studies, Inflammation by CHESS

Intestinal ischemia/reperfusion (I/R) injury often causes inflammatory responses and coagulation disorders, which is further promoting the deterioration of the disease. Hydrogen has anti-inflammatory, antioxidative, and antiapoptotic properties against various diseases. However, the effect of hydrogen on coagulation dysfunction after intestinal I/R and the underlying mechanism remains unclear. The purpose of this study was to explore whether hydrogen-rich solution (HRS) could …

Clinical application of molecular hydrogen in hemodialysis

In Review papers by CHESS

Increased oxidative stress and pro-inflammatory conditions, commonly present in chronic dialysis patients, are thought to be enhanced during hemodialysis (HD) and to be associated with the excess morbidity and mortality seen in these patients. The hydrogen molecule (H2) has a unique biological capacity to act as an antioxidative and anti-inflammatory substance. In light of accumulating evidence from animal studies showing …

Injection of hydrogen-rich solution attenuates intestinal ischemia-reperfusion injury

In Animal studies, Gut by CHESS

Luminal preservation of the intestine is an attractive method to locally mitigate preservation injury and ischemic-reperfusion injury in small bowel transplantation (SBT) because this method has a potential to maintain the intestinal graft integrity. Hydrogen is noted as an antioxidant material by reducing hydroxyl radicals. Authors hypothesized that hydrogen-containing solution can be an optimum material for luminal preservation method in …

Hydrogen solution protects against intestinal injury

In Animal studies, Gut by CHESS

Intestinal tissue got largely decreased blood supply in uncontrolled hemorrhagic shock, because of limited blood mainly supporting brain, heart, kidney etc. This makes intestine as the primary injury target after uncontrolled hemorrhagic shock. However, limited studies focus on how to protect intestine against hemorrhagic shock. Ringer’s solution, pentoxifylline and hypertonic saline are widely used to resuscitate in haemorrhagic shock and …

Effects of three hydrogen-rich liquids on lung injury-induced hemorrhagic shock

In Animal studies, Lung by CHESS

Hydrogen-rich saline provides a high concentration of hydrogen, which selectively reduces levels of hydroxyl radicals and alleviates acute oxidative stress in many models. Authors investigated the protective effects and mechanisms of three different hydrogen-rich liquid resuscitation preparations on lung injury-induced uncontrolled-hemorrhagic shock (UHS) in rats. A UHS rat model was prepared using the method of Capone et al. of arterial bleeding …

Transperitoneal administration of hydrogen suppress peritoneal and systemic oxidative stress

In Human studies, Kidney by CHESS

Oxidative stress (OS) related to glucose degradation products such as methylglyoxal is reportedly associated with peritoneal deterioration in patients treated with peritoneal dialysis (PD). However, the use of general antioxidant agents is limited due to their harmful effects. This study aimed to clarify the influence of the novel antioxidant molecular hydrogen (H2) on peritoneal OS using albumin redox state as …

Hydrogen as a new class of radioprotective agent

In Review papers by CHESS

It is well known that most of the ionizing radiation-induced damage is caused by hydroxyl radicals (·OH) follows radiolysis of H2O. Molecular hydrogen (H2) has antioxidant activities by selectively reducing ·OH and peroxynitrite(ONOO-). Authors firstly hypothesized and demonstrated the radioprotective effect of H2 in vitro and in vivo, which was also repeated on different experimental animal models by different departments. …

Hydrogen exerts metabolic effects similar to those of insulin in type 2 diabetic mice

In Animal studies, Metabolism by CHESS

Hydrogen (H(2)) acts as a therapeutic antioxidant. However, there are few reports on H(2) function in other capacities in diabetes mellitus (DM). Therefore, in this study, authors investigated the role of H(2) in glucose transport by studying cultured mouse C2C12 cells and human hepatoma Hep-G2 cells in vitro, in addition to three types of diabetic mice [Streptozotocin (STZ)-induced type 1 …

Aerosol inhalation of hydrogen-rich solution for prevention of radiation pneumonitis

In Animal studies, Lung by CHESS

Radiotherapy is an important modality of cancer treatment. Radiation pneumonitis is a major obstacle to increasing the radiation dose in radiotherapy, and it is important to prevent this radiation-induced complication. Recent studies show that hydrogen has a potential as an effective and safe radioprotective agent by selectively reducing hydroxyl and peroxynitrite radicals. Since most of the ionizing radiation-induced cellular damage …
