Component
Renal prostaglandin and prostacyclin synthesis measured by urinary excretion
Renal prostaglandin and prostacyclin synthesis measured by urinary excretion. Species, exposure and limitations are retained in each linked claim.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
Where it participates (unsigned role)
Single doses of 6 to 100 milligrams of aspirin produced a linear inhibition of platelet thromboxane B2 production ranging from 12 to 95% after 24 hours, and a daily dose of 0.45 milligrams per kilogram for 7 days produced cumulative and virtually complete inhibition without significantly reducing urinary excretion of prostaglandin E2, prostaglandin F2-alpha or 6-keto-prostaglandin F1-alpha in both men and women, an effect maintained unaltered through one month of therapy with no cumulative inhibition of renal prostaglandin synthesis, while furosemide-induced renal prostacyclin synthesis and renin release were unaffected.

- experimental_model
- Radioimmunoassay of serum thromboxane B2 and urinary prostaglandin excretion in 46 healthy subjects given single or repeated oral aspirin
- exposure
- Single doses of 6 to 100 milligrams, and 0.45 milligrams per kilogram daily for 7 days and up to one month
- limitations
- The dose-ranging design across 46 subjects is what makes the selectivity claim testable. Urinary prostaglandin excretion is an indirect measure of renal synthesis.
