  • Title: Effect of 3-methylindole on the plasma and lung concentrations of prostaglandins and thromboxane B2 in goats.
    Author: Acton KS, Bray TM, Boermans HJ.
    Journal: Comp Biochem Physiol A Comp Physiol; 1989; 94(4):677-81. PubMed ID: 2575955.
    Abstract:
    1. The role of prostanoids in 3-methylindole (3MI)-induced lung disease was investigated. Goats were infused with 3MI in propylene glycol at a dose of 35 mg 3MI/kg body weight. Control goats were infused with propylene glycol alone. 2. Blood was collected at regular intervals starting 24 hr before and ending 72 hr following 3MI infusion. In a second experiment, 3MI-treated goats were killed at 2, 6, 12, 24, 48 and 72 hr post-infusion. The concentrations of PGF2 alpha, PGE, 6-keto PGF1 alpha and TXB2 in plasma and lung of 3MI-infused and control goats were determined by radioimmunoassay. 3. Comparison of individual prostanoid concentrations showed that 3MI-infused and control goats exhibited similar plasma profiles for all four prostanoids measured. 4. In addition, prostanoid concentrations in lungs did not seem to be affected by 3MI infusion. 5. Thus, plasma and lung prostaglandin and TXB2 concentrations do not appear to be altered in 3MI-induced lung disease.
