ABSTRACT
To determine if the induction of immune-mediated glomerular injury influences the formation of glomerular cyclooxygenase products, we measured thromboxane B2 (TXB2), 6-keto-prostaglandin F1 alpha (6-keto-PGF1 alpha) and prostaglandin E2 (PGE2) production by isolated glomeruli of rabbits induced with acute serum sickness nephritis by the administration of bovine serum ablumin (BSA). Animals were randomly assigned to one of three experimental groups animals injected with BSA (BSA group; n = 11); animals injected with normal saline (control group; n = 11); and animals injected with BSA which were treated with the thromboxane synthetase inhibitor, OKY-046 (BSA + OKY-046; n = 6). Animals in the BSA and BSA + OKY groups developed severe proteinuria and glomerular histologic lesions of nephritis. No differences in proteinuria, serum creatinine and severity of histologic nephritis were observed between the two groups. Examination of glomerular eicosanoid production at the end of the experiment showed a marked reduction of glomerular PGE2 and 6-keto-PGF1 alpha production with a smaller reduction of glomerular TXB2 production in the BSA group. In the BSA + OKY-046 group, the production of TXB2 was significantly less than that in the BSA group; despite this, no effect on proteinuria could be discerned.
