Effect of pyridoxine on prostaglandin synthesis in rabbit kidney medulla slices.
Pyridoxine stimulated the generation of prostaglandin E2 in rabbit kidney medulla slices. Moreover, pyridoxine in the presence of aspirin reduced the release of linoleic acid, but enhanced the release of arachidonic acid from the medulla slices as compared with aspirin alone, indicating that the enhancement of prostaglandin E2 formation elicited by pyridoxine may be ascribed to an increased conversion of linoleic acid to arachidonic acid. These results suggest that pyridoxine can be an important modulating factor in prostaglandin synthesis by the kidney.
