TL;DR
Breathing in hydrogen gas can reduce kidney damage caused by temporary loss and restoration of blood flow in rats.
Key Finding
Inhaling 2.5% hydrogen gas reduced kidney damage markers and improved tissue health in rats experiencing ischemia/reperfusion injury (temporary loss and restoration of blood flow).
Summary
Researchers tested whether inhaling hydrogen gas could protect rat kidneys from damage caused by temporarily cutting off blood flow and then restoring it. Rats that breathed 2.5% hydrogen gas showed less kidney damage, lower levels of harmful molecules (oxidative stress markers), and better tissue appearance compared to rats that didn't receive hydrogen treatment.
Practical Takeaway
This rat study suggests hydrogen inhalation may help protect kidneys from ischemia/reperfusion injury, but these results are preliminary and from animal models only. Human clinical trials would be needed to determine if hydrogen therapy could be effective for kidney protection in people.
Abstract
To investigate the protective effects of hydrogen on renal ischemic/reperfusion injury and its mechanism in rats. Eighteen adult male Sprague-Dawley rats were used and allocated into sham-operated group (Sham group), ischemic reperfusion group (I/R group) and hydrogen treated group (H2 group) randomly. Ischemic/reperfusion of the left renal pedicles following a right nephrectomy was investigated in I/R group. In the Sham group, the rats were subjected to identical surgical procedure without occlusion of left renal pedicles. In the H2 group, inhalation of the 2.5% hydrogen was initiated 10 min before reperfusion and last for 130 min till the end of the 120-min reperfusion. Plasma level of usea nitrogen (BUN), creatinine (Cr), maiondiaidehyde (MDA), the score of histopathological examination of left kidney were evaluated 24 h after operation in all subjects. Ischemia-reperfusion injury rat model was established successfully. Inhalation of hydrogen (2.5%) markedly reduced the level of serum BUN, CREA and MDA (P < 0.05). The histopathological outcome in the H2 group was significantly improved, compared to the I/R group (P < 0.05). Inhalation of hydrogen could attenuate renal ischemic/reperfusion injury in rats by decreasing the content of MDA.
