OBJECTIVE:
The aim of this study was to explore the changes of the extracellular matrix in nasal mucosa by a guinea pig model of prolonged allergic-induced rhinitis.
METHOD:
Thirty-two male Hartley guinea pigs were randomly divided into four groups: allergen challenged groups (Group 2 w, Group 6 w and Group 12 w) and a control group. Ovalbumin-sensitized guinea pigs were repeatedly challenged with allergen twice a week from 2 weeks to 12 weeks. Matched control groups were challenged with physiological saline. Nasal mucosa were obtained from the animals killed. Hematoxylin-Eosin, Masson's trichrome, and immunohistochemical staining against transforming growth factor-beta1 (TGF-beta1), Collagen III and Collagen I were performed to nasal mucosa.
RESULT:
(1) Pathological examination showed obvious infiltration of eosinophils and the enlarged thickness of epithelial layer of nasal mucosa in the experiment groups. (2) The area ratios of blue stained in the extracellular matrix of nasal mucosa were increased. The area ratios of blue stained were statistically different in Group 6 w and Group 12 w compared with the control group. (3) The increasing absorbance of TGF-beta1 were statistically different in the experiment groups with the control group. The absorbance of Collagen III and Collagen I showed a rising trend along prolonged allergen challenged in the experiment groups.
CONCLUSION
Prolonged allergen challenge and the inflammation of nasal mucosa, can lead to the increasing of the inflammation relevant factors and the deposit of collagen in the extracellular matrix of nasal mucosa.

OBJECTIVE:
To investigate the expression of interleukin (IL)-23 in the nasal mucosa of allergic rhinitis patients and its significance.
METHOD:
mRNA and protein expression of IL-23 in inferior turbinate mucosa from 12 allergic rhinitis patients and 11 control patients was measured by means of real-time RT-PCR and immunohistochemistry, respectively.
RESULT:
IL-23p19 mRNA relative expression level in nasal mucosa was significantly increased in allergic rhinitis patients compared with normal controls (P < 0.01). Immunohistochemical staining demonstrated that IL-23 protein was mainly expressed by infiltrating inflammatory cells in lamina propria and there was increased number of IL-23 positive cells in allergic rhinitis patients in comparison with normal controls. Correlation analysis showed that the mRNA and protein expression level of IL-23 was significantly positively correlated with the number of the inflammatory cells (r = 0.678 and 0.644, respectively; both P < 0.01) and the degree of subepithelial collagen deposition (r = 0.834 and 0.721, respectively; both P < 0.01). IL-23p19 mRNA relative expression level in nasal mucosa was significantly decreased in allergic rhinitis patients who used glucocorticoids compared with controls (P < 0.01).
CONCLUSION
IL-23 may contribute to the chronic inflammation and airway remodelling in allergic rhinitis.

This study was aimed to evaluate the prevalence of soy protein hypersensitivity in cow's milk protein-sensitive children in Korea. A total of 1,363 patients with atopic dermatitis, urticaria, enterocolitis syndrome, bronchial asthma or allergic rhinitis were recruited. First, we estimated the prevalence of sensitization to soy in children sensitized to cow's milk. Specific IgE levels > 0.7 kU/L by CAP assay were considered positive. Next, the prevalence of soy allergy in cow's milk allergy (CMA) patients was investigated. Those children whose parents agreed to participate the open challenge test with soy had a convincing history of allergic reactions elicited by cow's milk and these symptoms were relieved by elimination. All of them had negative soy-specific IgE. Patients with positive soy-specific IgE accounted for 18.3% of 224 children sensitized to cow's milk protein. The prevalence of sensitization to soy decreased with age (36.8% in the first year of life, 16.4% in the second year, and 13.7% in the third year). Of 21 CMA patients, 42.9% (n=9) were determined to have soy allergy (mean age 10.3 months). Our results suggest that soy protein formula should be carefully used as a substitute for cow's milk in CMA patients, especially during infancy.

OBJECTIVE:
To evaluate the function of Th17 cells in allergic rhinitis,through comparing the symptoms, pathology and and the quantity of Th1, Th2 and Th17 cytokine in normal mice, allergic rhinitis mice and allergic rhinitis mice with IL-17 antibody application.
METHOD:
Thirty BALB/c mice were randomly divided into three groups, control group, allergic rhinitis group, and therapy group. The allergic rhinitis model was induced by classical method with ovalbumin. The therapy group was treated with IL-17 antibody. The concentration of IL-17, IL-4 and IFN-gamma in serum was measured by enzyme-linked immunosorbent assay (ELISA). Nasal mucosal inflammation was evaluated by HE staining. The expression of RORgammat mRNA was measured by reverse transcription-polymerase chain reaction (RT-PCR).
RESULTS:
The expression level of IL-17, IL-4 and RORgammat mRNA in allergic rhinitis group were significantly higher than those of control group and IL-17 antibody treated group (P < 0.05). While the expression level of IFN-gamma in allergic rhinitis group were significantly was lower than those of control group and IL-17 antibody treated group (P < 0.05). The inflammation reaction in therapy group abated with nasal mucosal HE staining.
CONCLUSION
The large quantity of Th2, Th17 cells were found in allergic rhinitis. It might be associated with the pathogenesis of allergic rhinitis. The control of Th17 cells expression may be an effective way to treat allergic rhinitis.

Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2008;22(17):780-784
OBJECTIVE:
To investigate the expression of costimulatory molecules CD28/B7 and CD40/CD40L in T and B lymphocytes as well as its relations with total IgE (TIgE), eosinophil cationic protein (ECP) in serum and nasal allergic symptoms in patients with allergic rhinitis (AR). The effect of specific immunotherapy (SIT) on them were also investigated.
METHOD:
Thirty allergic allergic rhinitis patients were chosen as observation group, and 30 healthy patients as control group. Cytofluorometric analysis was used to compare the expression level of CD28/B7-1, B7-2 and CD40/CD40L on T cells and B cells in the two groups. The relationship between the CD28/ B7-1, B7-2 and CD40/CD40L expression level and serum Total IgE, ECP level were analyzed.
RESULT:
The expression level of CD28/B7-2 and CD40/CD40L on T cells and B cells in allergic rhinitis patients were significantly higher than in the healthy, and serum level of TIgE has a positive relationship with the expression level of CD40L on T cells. ECP has a positive relationship with the expression level of B7-2 on B cells. The expression level of B7-1 showed no significant difference between the two groups. After specific immunotherapy for 6 months, the expression level of CD28/B7-2 and CD40/CD40L on T cells and B cells were decreased in allergic rhinitis patients but still higher than in healthy.
CONCLUSIONS
The upregulated level of costimulatory molecules CD28/B7-2 and CD40/ CD40L on T cells and B cells may play an important role in the pathogenesis of allergic rhinitis, specific immunotherapy can downregulate the expression level of CD28/B7-2 and CD40/CD40L, and decrease the serum level of TIgE, it may be a possible mechanism in the treatment of allergic rhinitis.

OBJECTIVES:
To investigate the expression of IL-25,IL-33 and EOS in children with allergic rhinitis (AR).
METHODS:
Ninety-four AR children receiving immunotherapy and 23 healthy people were concluded in the study. The serum levels of IL-25 and IL-33 were detected by Enzyme-linked Immunosorbent Assay (ELISA), and a count of EOS were measured.
RESULTS:
The serum levels of IL-25 and IL-33 in the mild group were higher than control group (<0.05). The count of EOS showed no difference between the mild group and the control group (>0.05). The serum levels of IL-25 and IL-33 in the severe group were higher than those in mild group (<0.05). The serum levels of IL-25 and IL-33 in the severe group were higher than control group (<0.05). The count of EOS in the severe group were higher than those in mild group (<0.05). The count of EOS in the severe group were higher than those in control group (<0.05). Spearman test showed the serum levels of IL-25 in the children with AR patients have positive correlation with the serum levels of IL-33 (<0.05, =0.238).
CONCLUSIONS
Expression of IL-25 levels, IL-33 levels and the count of EOS in patients with AR are enhanced, which shows that IL-25, IL-33 and the count of EOS are involved in the AR. If we can understand the mechanism of them, it will profound implications for treatment.

OBJECTIVE:
To investigate the expression and role of Interleukin-33 (IL-33) and ST2 in the nasal polyps of human Eosinophilic and non-Eosinophilic chronic rhinosinusitis with nasal polyps (ECRS and non-ECRS).
METHOD:
IL-33 and ST2 protein expression in nasal polyps of ECRS and non-ECRS as well as in seemingly normal mucosa of the inferior turbinate tissue was investigated by immunohistochemical staining and messenger RNA (mRNA) expression of IL-33 and ST2 was assessed by realtime polymerase chain reaction (PCR) in 27 subjects with ECRS, 33 subjects with non-ECRS, and 11 control subjects.
RESULT:
(1) The ST2 was found both in nasal polyps of ECRS and non-ECRS,especially in ECRS, yet hardly found in the normal mucosa of the inferior turbinate tissue; (2) The expression of ST2 mRNA in nasal polyps of ECRS was higher than that in non-ECRS and normal inferior turbinate tissue, and the difference was both prominent in statistics (P<0.01); (3) The expression patterns of IL-33 at both mRNA and protein levels were not significantly different among the three groups (P>0.05).
CONCLUSION
The IL-33 and its receptor ST2 were both expressed in human nasal polyps including ECRS and non-ECRS, meanwhile the expression patterns of ST2 at both mRNA and protein levels were significantly higher in nasal polyps of ECRS. The current study suggests that IL-33 and its receptor ST2 may play important roles in the pathogenesis of chronic rhinosinusitis with nasal polyps, especially in ECRS through the increased expression of ST2 in Eosinophils as a hypothesis.
