Fig. 6From: IL-5 and IL-6 are increased in the frontal recess of eosinophilic chronic rhinosinusitis patientsMeasurement of TGF-β, IL-5, IL-6, and iNOS in 20 non-eosinophilic chronic rhinosinusitis (non-ECRS) patients by RT-PCR. In non-ECRS patients, there are no significant difference of any cytokine expression among frontal recess mucosa, ethmoid sinus mucosa and nasal polyp. Data are presented as the mean values and error bars indicate standard deviation. FR = frontal recess; Eth = ethmoid sinus; NP = nasal polyp; N.S. = not significantBack to article page
