OBJECTIVE
We have found that expression of γδT cells is increased in pathological mucosa of chronic rhinosinusitis with nasal polyps (CRSwNP) compared with normal nasal mucosa. This increase is correlated with the infiltration of eosinophils in CRSwNP. Here, we investigated the expression of γδT
BACKGROUND
The aim of this study was to investigate the expression of Aquaporin 1 (AQP1) and AQP4 in polyp tissue.
METHODS
Nasal polyps were obtained from 34 patients with nasal polyposis during endoscopic sinus surgery. Bullous middle turbinates with normal-appearing mucosa of 10 patients were used
OBJECTIVE
To study the effects of intranasal FP on the expression of AQP-2 in nasal polyps.
METHODS
Fourteen cases of type II phase 3 and 12 cases of type III nasal polyps were selected. FP were intranasally used in 7 cases of type II phase 3 and 6 cases of type III nasal polyps for 7 days before
BACKGROUND
Nasal polyps (NP), a subgroup of chronic rhinosinusitis, are characterized by interleukin 5 (IL-5) mediated infiltration of eosinophils in sinus mucosa, leading to pseudostratified ciliated columnar epithelium, thickening of the epithelial basement membrane and tissue edema. Matrix
OBJECTIVE
To detect the expression of AQP5, HIF-1alpha and VEGF in human nasal polyps, and to observe the relationship of AQP5 with HIF-1a and VEGF, and to investigate their role in the pathogenesis of nasal polyps.
METHODS
Using the techniques of Real-time Quantitative Polymerase chain Reaction and
Purpose: Nasal douching is commonly used as a postoperative management strategy for chronic rhinosinusitis with nasal polyps (CRSwNP). Few studies to date have compared the effectiveness of nasal douching in CRSwNP phenotypes after
Inhaled nasal corticosteroid sprays (INS) are often inadequate to treat chronic rhinosinusitis (CRS). The exhalation delivery system with fluticasone (EDS-FLU; XHANCE®) may improve outcomes in CRS by increasing medication delivery to target superior/posterior anatomic sites. This study OBJECTIVE
To study the clinicopathologic significance of microvessel density (MVD) and the expression of CD34 in human nasal polyps.
METHODS
Using Elivision Plus immunohistochemistry method. Thirty cases of normal inferior turbinate, 60 cases of nasal polyps were stain with CD34.
RESULTS
MVD of CD34
OBJECTIVE
To study the expression and significance of vascular permeability factor(VPF) in nasal polyps.
METHODS
Expression of VPF and its receptor flk-1 in nasal polyps from 9 patients and inferior turbinates from 8 patients with chronic rhinitis were prospectively studied with
OBJECTIVE
To study the expression and significance of vascular permeability factor (VPF) in eosinophil, macrophage and plasma cell in nasal polyps.
METHODS
VPF in 12 nasal polyps was studied by immunohistochemistry, double immune-enzymatic staining technique and double MGG staining technique. Each
OBJECTIVE
To confirm the expression and distribution of Aquaporin 1 (AQP1) in the nasal polyps and to investigate the relation between AQP1 and the nasal polyp edema.
METHODS
fourteen cases of normal inferior turbinates and 26 cases of nasal polyps were used. The expression and distribution of AQP1
OBJECTIVE
To estimate the predictable value of histopathologic parameters in chronic rhinosinusitis with nasal polyps (CRSwNP) after endoscopic sinus surgery(ESS).
METHODS
Symptomatology was rated in 53 patients 12 to 24 months after ESS. Specimens taken during the surgical procedure were examined
MMPs (metalloproteinases) and their inhibitor TIMP (tissue inhibitor of metalloproteinases) are important in tissue remodeling and have been implicated in nasal polyp pathophysiology. The objective of the present study was to evaluate gene expression of MMP-1, MMP-2, MMP-9 and TIMP-1 gene expression
OBJECTIVE
To evaluate the expression of epithelial sodium channel in nasal polyps and normal nasal mucosa and to characterize the ENaC-mediated Na(+) absorption and the mechanism of the liquid transport in human upper airway epithelia.
METHODS
The tissue from 12 patients with nasal polyps (NP) and
