Expression of inflammatory-reparative proteins in patients with chronic rhinitis, pharyngitis or sinusitis undergoing thermal water nasal inhalation and controls. Nasal epithelial cells from healthy subjects and from patients at time T0 and T1 were obtained and lysed as described under Methods. Proteins were separated by electrophoresis and expression of CXCR4 was measured by western blot in control subjects (upper panel) and in patients (lower panel). Each patient had two codes, one for time T0 (odd columns, e.g. 61 for the first patient, 112 for the second etc.) and one for T1 (even columns; e.g. 251for the first patient, 325 for the second etc.). β-actin was used as loading control and for densitometric analysis
