Study at a glance
Preclinical
rats, rat, tissue, tissues used to study other neurological conditions.
Full text reports H₂ dissolved in saline. Detected intervention quantities or schedules: 0.25 mL/kg, 24 hours, 60%, 0.6 mM, 30%. · H₂-related quantities reported in the intervention passages: 0.25 mL/kg, 24 hours, 60%, 0.6 mM, 30%. Values are not combined across different experimental arms.
24 hours
Article-reported result excerpt (24 words maximum): “Results at 24 hours, 48 hours, 1 week and 2 weeks after injury showed that hydrogen-rich saline markedly reduced cell death, inflammatory cell infiltration,…” This excerpt is not a complete result summary; consult the linked full text for all positive and null findings.
Preclinical evidence only; findings do not establish a treatment effect in people. Funding or grant information is reported in the full article. No explicit conflict statement was identified in the machine-readable full article; absence is not inferred.

Information not yet classified
Some editorial classification fields are still pending. The source-reported outcomes and result are shown below; Hydrogenology does not infer a positive or negative signal from prose automatically.
Methods
rats, rat, tissue, tissues used to study other neurological conditions.
Preclinical study; group or assay counts reported in the full text include n=25, n=50.
24 hours
Full text reports H₂ dissolved in saline. Detected intervention quantities or schedules: 0.25 mL/kg, 24 hours, 60%, 0.6 mM, 30%.
H₂ dissolved in saline — H₂ only unless the full text explicitly reports oxygen co-delivery.
H₂-related quantities reported in the intervention passages: 0.25 mL/kg, 24 hours, 60%, 0.6 mM, 30%. Values are not combined across different experimental arms.
Control or comparison condition reported in the full article; see the linked methods for arm-specific details.
Outcomes and reported result
survival or mortality, clinical symptoms or functional scores, oxidative-stress and antioxidant markers, apoptosis or cell injury, metabolic laboratory measures, neurological or behavioral measures

The complete machine-readable article was checked for source identity, methods, intervention quantities, results, tables, funding and conflict declarations. This public record is based on the full article.
A reported association, difference or mechanism is not automatically a clinical benefit.
Limitations and applicability
Preclinical evidence only; findings do not establish a treatment effect in people. Funding or grant information is reported in the full article. No explicit conflict statement was identified in the machine-readable full article; absence is not inferred.
Applies to the reported animal, cell or tissue model for other neurological conditions, not directly to patients.
No single-study GRADE certainty rating is assigned. Read how records and evidence assessments are prepared.
