To clarify the mechanisms by which Triton WR-1339 causes an elevation in the plasma fibrinogen level, we studied the time courses of hepatic mRNA expression for beta-chain fibrinogen, interleukin-6 (IL-6) and IL-6 receptor (R) by RT-PCR. After intravenous injection of Triton WR-1339 (150, 300 and 500 mg/kg) in Sprague-Dawley rats, the plasma level of fibrinogen and MCP-1 significantly and dose-...
