IL6 and endometritis: Thus, this study aimed to determine gene transcription of NF‐κB subunits (RelA; NF‐κB1; NF‐κB2), proinflammatory molecules (MCP‐1; IL‐6) and hyaluronan synthases (HAS 1; HAS 2; HAS 3) in endometritis and compare them with the intensity and type of inflammatory cell infiltration.
