TL;DR
Washing the pancreas with a special acidic water can prevent bacterial contamination without harming the pancreas, but it can slightly damage the cells if they're washed directly after being isolated.
Key Finding
Acidic oxidative potential water effectively prevented bacterial contamination on harvested pancreatic tissue, but direct application to isolated islet cells reduced their viability and function.
Summary
Researchers tested a special acidic water (created through electrolysis) to prevent bacterial contamination during the preparation of pancreatic islets (insulin-producing cells) harvested from pigs for potential transplantation. The water was highly effective at killing bacteria on the pancreas surface, but when applied directly to the isolated islet cells themselves, it slightly reduced their viability and function.
Practical Takeaway
This study was conducted in pigs and focused on preventing bacterial contamination during a specialized medical procedure (islet transplantation), not on hydrogen water as a health supplement. The findings do not apply to drinking hydrogen water or other consumer health applications. The study suggests that the timing and method of applying antimicrobial solutions matters—preventing contamination without damaging the cells being preserved is a key challenge in transplant medicine.
Abstract (excerpt)
At a number of points in the current procedures of islet isolation and islet culture after the harvesting of donor pancreata, microorganisms could potentially infect the islet preparation. Furthermore, the use of islets from multiple donors can compound the risks of contamination of individual…
