Abstract:Tissue distribution, elimination, and metabolism of 3H-labelled leukotriene (LT) C4 were studied in ureter-catheterized conscious marine toads, Bufo marinus. Six and 24 h after injection, organs containing the highest percent of injected radioactivity were small intestine, liver, and kidney. Radioactivity declined in these organs at 24 h by approximately threefold. Peak elimination time for radioactivity in the urine was between 2 and 4 h after the injection. During the 24-h collection period, 55.2 +/- 0.2% of… 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.
