1982 · Murakami — Contact electrode method in hydrogen gas clearance technique: a new method for determination of regional gastric mucosal blood flow in animals and humans.
Super-Abstract
A new contact electrode method for hydrogen gas clearance was developed to measure regional gastric mucosal blood flow non-destructively, tested in both animal models and human subjects. The abstract of this publication is not available in the source database.

Commentary
This paper describes a technical innovation in the hydrogen gas clearance method — specifically the use of a contact electrode applied endoscopically to measure regional gastric mucosal blood flow without tissue removal. Hydrogen gas clearance was a widely-used physiological measurement technique in this era: patients or animals inhale a small amount of H₂, and an electrode measures how quickly it disappears from the local tissue, which reflects perfusion rate. This is a methodological paper; hydrogen gas is used purely as a diagnostic tracer, not as a therapeutic agent. No abstract text is available to quote from directly.

Our assessment
This is a methodological study introducing a technical improvement to hydrogen gas clearance blood flow measurement. H₂ is a diagnostic tracer, not a therapeutic molecule. Note: the abstract is not available in the source database; the above summary is based solely on the title and bibliographic context. No therapeutic conclusions can be drawn, and readers are referred to the original publication for details.
Study design
- Type: animal + human methodological study · H₂ role: inert gas tracer for blood flow measurement via contact electrode clearance (not therapeutic)
- Result: abstract unavailable — see original publication in Gastroenterology, 1982 for full data
