To evaluate the effect of endotoxin administration on the glucuronidation of multiple substrates in a rat model. In addition, the effect of endotoxin treatment on selected UGT mRNA levels in the liver and the kidney was also investigated. Male Sprague-Dawley rats (n= 6) received endotoxin (1.6 mg/kg) by intraperitoneal injection. The animals were sacrificed at 6, 12, 24, 48 hr after treatment, and the liver and the kidneys were harvested. Glucuronidation of various substrates (i.e., acetaminophen, estradiol, testosterone, and morphine) was evaluated using prepared tissue microsomes. Real-Time PCR was used to determine mRNA levels of UGT1A1, 1A6, 2B1, and 2B3 in the harvested organs. UGT1A an..
