Hydrogen Gas Inhalation (4%) could Reduce Lung Inflammation and Blood Pressure in Rats with Monocrotaline-Induced Pulmonary Hypertension | Chapter 9 | Medicine and Medical Research: New Perspectives Vol. 2

 

The aim of this study was to investigate the effects of inhaling atmospheric air containing 4% hydrogen on the symptoms and progression of PH in male Wistar rats using the MCT-induced model. Interstitial lung diseases (IPD), associated with inflammatory processes and the appearance of fibrosis, lead to impaired ventilation-perfusion ratio and hypoxia. Recently, strategies and drug approaches for the treatment of IPD-associated pulmonary hypertension have been widely discussed. Hydrogen has been shown to exhibit selective antioxidant properties against hydroxyl radicals and exert antioxidant and anti-inflammatory effects. Because monocrotaline causes oxidative stress, the monocrotaline-induced model of pulmonary hypertension is appropriate for researching compounds having antioxidant properties. On day 1, male Wistar rats were subcutaneously injected with either a water-alcohol solution of monocrotaline or control solution consisting solely of water and alcohol. One group of monocrotaline-injected animals was placed in a plastic box continuously ventilated with atmospheric air containing 4% molecular hydrogen, while the two other groups (one injected with monocrotaline and the other with vehicle) were placed in boxes ventilated with atmospheric air. After 21 days, hemodynamic parameters were measured under urethane narcosis. The results showed that, although hydrogen inhalation had no effect on the main markers of pulmonary hypertension induced by monocrotaline injection, there was a reduction in systemic blood pressure due to its systolic component, and a decrease in TGF- β expression, as well as a reduction in tryptase-containing mast cells. The results in combination with previous published results indicate that molecular hydrogen may be a useful therapeutic agent to combat pulmonary hypertension. Further research with larger sample sizes and exploring different routes of administration, concentrations and durations is needed to determine the optimal therapeutic approach. Overall, these findings suggest that molecular hydrogen may hold promise as a therapeutic agent in the treatment of pulmonary hypertension, in patients but further investigation is warranted.

An In-silico Analysis and Narrative Synopsis Confirming the Invalidity of ORP Use in Estimating Aqueous H2 Concentration | Chapter 4 | Recent Developments in Chemistry and Biochemistry Research Vol. 6

The aim of the study is to conduct an In-Silico Analysis and provide a Narrative Synopsis Confirming the Invalidity of ORP Use in Estimating Aqueous H2 Concentration. Oxidation-Reduction Potential (ORP) is often used to characterize functional beverages, specifically alkaline ionized water and hydrogen water. Numerous health benefits including antioxidant effects have been attributed to a negative ORP value. However, a greater negative ORP value is often incorrectly interpreted to mean a greater degree of health benefits and/or a high concentration of H2. However, ORP is not specific to H2 gas but any redox-active molecules. Recent fatalities have occurred due to conflating a negative ORP with health benefits due to the use of toxic chemicals to induce a negative ORP. Additionally, when ORP meters are used to estimate H2 gas, the readings can be highly unreliable. For example, hydrogen meters use the Nernst equation to calculate the concentration of H2 based on the measured ORP value. Unfortunately, due to the fundamental limitations of the ORP meter, the calculated H2 value may be very inaccurate. Using the Nernst equation, we performed an in-silico analysis of the ORP as a function of pH, temperature, and H2 concentration. Our analysis shows that a one-unit increase in pH (e.g., 7-8) influences the ORP by as much as increasing the H2 concentration by 100 times (e.g., 1 to 100 mg/L). Similarly, at a saturated H2 concentration (1.57 mg/L) and pH 7, every ΔT of 20°C changes the ORP by ≈ 30 mV. This is comparable to changing the H2 concentration by a factor of 10 (0.1 mg/L to 1 mg/L).  Moreover, to measure H2 within 0.1 mg/L, ORP meters need to have an accuracy of about 0.8 mV. However, ORP meters have an error range of at least ±10 mV, which corresponds to a potential error in measured H2 concentration of nearly 2 mg/L (≈125% error). This analysis shows that pH, temperature, and intrinsic ORP errors can individually influence the ORP greater than the entire contribution of dissolved H2 within normally used ranges. Consequently, this can easily result in a water sample with a greater negative ORP than another despite having significantly less H2. Thus, it becomes impossible to consistently determine if one water sample has more H2 than another water sample. However, the analyses and calculations were performed only with the variables included in the equations, which can be considered a limitation of this study. Finally, we can only conclude, based on a negative ORP reading, that, excluding the possibility of other reductive redox couples, some level of dissolved H2 is present in the water. Accordingly, ORP and ORP-based H2 meters are not reliable for testing or comparing the concentration of H2 in water. Inherent fluctuations in the ORP meter, combined with the significant influence that even small deviations in pH and temperature have on the ORP, will always dominate the ORP measurement.

Beneficial Effects of Hydrogen Water on Subjects with NAFLD | Chapter 8 | Research Developments in Medicine and Medical Science Vol. 4

 Non-alcoholic greasy liver disease (NAFLD) is a liver disorder that influences approximately a quarter of the all-encompassing population. It is caused by an exuberance of oxidative stress, inflammation, and irregular cellular indicating, which can influence liver dysfunction and eventually, carcinoma. Molecular hydrogen has existed identified for allure specific antioxidant characteristics and ability to decrease inflammation and regulate natural activity. In a randomized, double-blind, fake pill-controlled trial unending eight weeks, hydrogen-rich water (HRW) was given to 30 matters with NAFLD. We noticed approving trends (p > 0.05) in abated weight (about 1 kg) and party mass index in the HRW group. HRW was well-indulged, with no significant changes in liver enzymes and an slant towards improved lipid sketch and lower lactate dehydrogenase levels. HRW went to decrease nuclear determinant kappa B, heat shock protein 70, and matrix metalloproteinase-9 levels non-significantly. Curiously, skilled was a slight but non-significant increase in the levels of 8-hydroxy-2’-deoxyguanosine and malondialdehyde in the HRW group. This gentle increase may desire hormetic effects of microscopic hydrogen. Further, longer-term studies focused on barring, maintaining, or discussing NAFLD and early stages of NASH are necessary.
