OBJECTIVE:
To investigate the influence of aluminum hydroxide adjuvant on a murine model of allergic rhinitis (AR) and to confirm an appropriate method of establishing a mouse model of AR.
METHOD:
Establishing two types of BALB/c mice models of AR, one was identified as Local group which was characterized through intranasal sensitization and challenge using ovalbumin (OVA), and the other Systemic group which was made by intraperitoneal sensitization with OVA plus aluminum hydroxide and intranasal challenge through OVA. Then the numbers of sneezing and nasal rubbing were counted after the last challenge and the eosinophils in the nasal mucosa of mice models were observed and counted though Luna stain. Furthermore, morphological hyperplasia was examined in intraepithelial goblet cells and submucosal glands with HE stain. In addition, interlukin (IL) -4, IL-5, OVA specific IgE (sIgE) and interferon (IFN)-gamma in nasal lavage fluid (NLF) and serum of mice were examined u sing enzyme linked immunosorbent assay (ELISA).
RESULT:
The counts of sneezing and nasal rubbing in local group were more than those in systemic group and eosinophilia in the nasal mucosa of former group was greater than that in the latter one. Morphological hyperplasia was stronger in intraepithelial goblet cells and submucosal glands in local group compared with that in systemic group. Furthermore, the contents of IL-4, IL-5 and sIgE increased in the NLF and serum of mice of local group compared to those of systemic one. However, the production of IFN-gamma of mice in local group decreased when compared with that in Systemic group.
CONCLUSION
OVA plus aluminum hydroxide adjuvant may promote Th1 type immune response as well as Th2 response. OVA intranasal sensitization and challenge locally is an appropriate way in the establishment of AR mice models.

OBJECTIVETo investigate the influence of normal saline nasal irrigation with different temperature on allergic rhinitis (AR) and to confirm the appropriate temperature of nasal irrigation.
METHODSSixty patients with AR were randomly divided into 3 groups (according to random number table) and received 15 °C, 25 °C or 40 °C normal saline nasal irrigation respectively, and 20 healthy controls received no treatment. Visual analogue scale ( VAS) was used to assess the symptoms among the control group and the various intervention groups and the enzyme linked immunosorbent assay (ELISA) was applied to detect the contents of histamine, leukotriene C4 (LTC4), house dust mite D1 specific IGE (sIGE) and eosinophil cationic protein (ECP) among the control group and the various intervention groups. GraphPad Prism 5 software was used to analyze the data.
RESULTSThere was no statistical difference between 15 °C normal saline nasal irrigation group and 25 °C normal saline nasal irrigation group. Pre-intervention and post intervention whether is VAS scores of rhinorrhea, sneezing, nasal obstruction and nasal pruritis or in contents of histamine, LTC4, sIgE and ECP showed no difference (all P > 0.05). However, the symptoms of (sneezing VAS score: 3.765 ± 0.291; nasal obstruction VAS score: 3.529 ± 0.365). The difference was significant (t = 4.678, P < 0.001; t = 3.901, P < 0.01). The contents of histamine [ (21.78 ± 0.62) ng/ml] and LTC4 (17.43 ± 0.67 ng/ml) were also decreased after intervention of 40 °C normal saline nasal irrigation [ histamine content: (18.82 ± 0.52) ng/ml; LTC4 content: (13.14 ± 0.59) ng/ml ]. The difference was significant (t = 3.632, P < 0.01; t = 4.79, P < 0.001). Nonetheless, there were no statistical differences in VAS scores of rhinorrhea (t = 2.02, P = 0.051) and nasal pruritis (t = 1.984, P =0.056) and in contents of sIgE (t = 1.891, P = 0.066) and ECP (t = 2.021, P = 0.05). There were statistical differences between the 40 °C group and the 25 °C group normal saline nasal irrigation group in symptoms of sneezing (t = 2.060, P = 0.048) and nasal obstruction (t = 2.1053, P = 0.048). and inflammatory factors of histamine (t = 2.078, P = 0.045) and LTC4 (t = 2.149, P = 0.038). In symptoms of rhinorrhea and nasal pruritis and local production of sIgE and ECP, there was no statistical difference (all P > 0.05).
CONCLUSION40 °C normal saline nasal irrigation can improve the symptoms of sneezing and nasal obstruction and can alleviate the local levels of inflammatory factors like histamine and LTC4 in AR patients, and is the appropriate irrigation temperature.

Objective To investigate the effects of adrenocorticotropic hormone (ACTH)combined with Huaiqihuang on hypothalamic pituitary adrenal (HPA) in rats. Methods Fifty rats were randomly divided into five groups according to the random number table method:normal control group (group A), prednisone group (group B), Huaiqihuang group (group C), ACTH group (group D) and combined treatment group (group E) with 10 rats in each group. Rats in group B, C, D and E were gavaged by acetic acid prednisone water solution 12.5 mg/(kg · d) for 4 weeks to establish HPA axis suppression model. Group A was given distilled water 10 mL/(kg·d) as control. Rats in group C and E were gavaged with Huaiqihuang 5 g/(kg·d) 30 minutes after intragastric administration of prednisone acetate. At the third week of the experiment, group D and E were subcutaneous injected with ACTH 200 μg/(kg·d). The serum cortisol levels were measured respectively at the start of the ex?periment, 2 weeks and 4 weeks of experiment. Animals were sacrificed at the end of the experiment, and then weights of the pituitary, adrenal glands and the viscera index were calculated. The pathological changes of the pituitary and adrenal glands were observed by HE stainning. Results After 2 weeks, the serum cortisol levels were significantly lower in group B, C, D and E than those of group A (P<0.05), suggesting that the model was successful. After 4 weeks, the serum cortisol levels were significantly higher in group C, D and E than those of group B (P<0.05), and between the treatment group the value was group E>group D>group C (P<0.05). At the same time, the weights of pituitary and adrenal gland and the viscera in?dex were higher in the three groups than those of B group (P<0.05). The HE staining showed that there were no significant changes in the distal part of the pituitary gland in five groups. The adrenal cortex zona was thinning and the structure was dis?ordered in group B. There were different degrees of hyperplasia in group C, group D, and group E, which was the most obvi?ous in group E. Conclusion ACTH combined with Huaiqihuang can promote adrenal cortex zona hyperplasia and cortisol secretion, which reduces the glucocorticoid induced inhibition of HPA axis in rats.
