Effect of biliary drainage on inducible nitric oxide synthase, CD14 and TGR5 expression in obstructive jaundice rats

Figure 4 Ethidium bromide-stained agarose gel of inducible nitric oxide synthase reverse transcription polymerase chain reaction products, expression of inducible nitric oxide synthase messenger RNA on Kupffer cell interfered with lipopolysaccharide + ursodeoxycholic acid. A: Lane M, 100 bp molecular marker. The 138 bp-inducible nitric oxide synthase (iNOS) band; B: The 300 bp-β-action products; C: Expression of iNOS messenger RNA (mRNA) interfered with lipopolysaccharide (LPS) as compared with LPS + ursodeoxycholic acid (UDCA). ^aP < 0.05, ^bP < 0.01 vs LPS + UDCA. M: Marker; ID: Internal biliary drainage; SH: Sham operation; ED: External biliary drainage; OJ: Obstructive jaundice.
