Hydrogen Research as a Therapeutic Medical Gas

Recent basic and clinical research has revealed that hydrogen is an important physiological regulatory factor with antioxi- dant, anti-inflammatory and anti-apoptotic protective effects on cells and organs. Therapeutic hydrogen has been applied by different delivery methods including straightforward inhalation, drinking hydrogen dissolved in water and injection with hydrogen-saturated saline. This review summarizes currently available data regarding the protective role of hydrogen, pro- vides an outline of recent advances in research on the use of hydrogen as a therapeutic medical gas in diverse models of disease and discusses the feasibility of hydrogen as a therapeutic strategy. It is not an overstatement to say that hydrogen’s impact on therapeutic and preventive medicine could be enormous in the future.
