Increase in enzyme activities of prostaglandin biosynthesis and catabolism by acute ureteral ligation in rat kidney.

Acute ureteral obstruction increased cyclooxygenase, thromboxane and prostacyclin synthases and NAD+-linked 15-hydroxyprostaglandin dehydrogenase activities in rat kidney. Significant increase in prostaglandin biosynthetic and catabolic activities may mediate some pathological consequences found in obstructive nephropathy.
