title: Radiation-induced alterations in prostaglandin excretion in the rat.
abstract: Dose-related alterations in the levels of prostaglandins (PGF2 alpha and PGE) and thromboxane B2 (TxB2) were observed in the urine of unanesthetized rats following whole-body gamma radiation. Exposure doses of 100 and 900 rads resulted in significant changes in urinary levels of these cyclooxygenase products. These findings suggest the potential use of radioimmunoassay measurement of urinary prostaglandins and thromboxane as a noninvasive indicator of radiation exposure.
