[Retracted] Effect of Erdosteine on Middle Ear Effusion in Rats by Mediating TLR4 Signaling Pathway

Table 3

Levels of TNF-β, MPO, and MMP.

Group	TNF-β (fmol/mL)	MPO (ng/mL)	MMP (ng/mL)
Normal group
Model group	^a	^a	^a
Treatment group		^b	^b

The levels of TNF-β, MPO, and MMP are elevated remarkably in the model group (), while they are reduced in the treatment group, which are close to those in the normal group. ^a vs. the normal group and ^b vs. the model group.
