چکیده
BackgroundMolecular hydrogen (H2) has protective effects against ischemia-reperfusion injury in various organs. Because they are easier to transport and safer use than inhaled H2, H2-rich solutions suitable for organ preservation. In this study, we examined the of an solution lung preservation a canine left transplantation (LTx) model.MethodsTen beagles underwent orthotopic LTx after 23 hours cold ischemia followed by reperfusion 4 hours. Forty-five minutes reperfusion, right main pulmonary artery was clamped evaluate function implanted graft. The were divided into two groups: control group (n = 5), H2 5). group, donor lungs flushed immersed during at 4°C using ET-Kyoto solution, these solution. Physiologic assessments performed reperfusion. After wet-to-dry ratios determined, histology examinations performed.ResultsSignificantly higher partial pressure arterial oxygen significantly lower carbon dioxide observed (P .045 P < .001, respectively). ratio .032). Moreover, examination, less fewer apoptotic cells .001 respectively).ConclusionsOur results demonstrated that attenuated model. Molecular Ten performed. Significantly Our

Protective Effects of Proline–Rich Peptide in a Rat Model of Alzheimer Disease: An Electrophysiological Study
Introduction: Alzheimer disease (AD) is the most common form of dementia in the elderly that slowly destroys memory and cognitive functions. The disease has no cure and leads to significant structural and functional brain abnormalities. To facilitate the treatment of this disease, we aimed to investigate proline-rich peptide (PRP-1) action of hypothalamus on hippocampal (HP) neurons and dynamic...
متن کاملProtective effects of hydrogen-rich saline on monocrotaline-induced pulmonary hypertension in a rat model
BACKGROUND Hydrogen-rich saline has been reported to have antioxidant and anti-inflammatory effects and effectively protect against organ damage. Oxidative stress and inflammation contribute to the pathogenesis and/or development of pulmonary hypertension. In this study, we investigated the effects of hydrogen-rich saline on the prevention of pulmonary hypertension induced by monocrotaline in a...
متن کاملProtective effects of hydrogen-rich saline in uncontrolled hemorrhagic shock
Hydrogen is considered to be a novel antioxidant as it inhibits inflammation, removes oxygen-derived free radicals and reduces oxidative damage. This study investigated the effects of hydrogen-rich saline on plasma interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), superoxide dismutase (SOD) and malondialdehyde (MDA) in rats with uncontrolled hemorrhagic shock (UHS). The UHS model was induc...
