Abstract:Little is known of the normal renal handling of potential uremic toxins in the middle molecular weight (MMW) range (300–2,000 daltons). In this study the isolated rat kidney has been used as a model to investigate renal clearance and possible renal metabolic effects on uremic MMW species. Isolated rat kidneys were perfused with hemofiltrate from chronic renal failure patients containing 5% bovine albumin. Middle molecules (MM) were isolated from perfusates and urines by high-speed gel filtration (peak 7) and f… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
