变应性鼻炎动物模型建立及白细胞介素6、10因子检测的初步报告栾兆磊;王雨农;王洪田【摘要】Objective To establish guinea pig model for allergic Rhinitis (AR) and detect interleukin 6 (IL-6) and interleukin 10(IL-10) in it. Methods Twenty Hartley guinea pigs were selected and randomly divided into experimental group and control group with each group of 10 animals. Ovalbumin (OVA) was used as allergen and aluminum hydroxide as adjuvant. The experiment included two stages, which were systemic sensitization and nose provocation, the experimental group was induced by intraperitoneal injection with OVA suspension 1 ml, once every two days for 7 times, and the control group was induced by intraperitoneal injection with normal saline 1 ml once every two days for 7 times. Three days after systemic sensitization, OVA solution was dropped into nose with 0.05 ml for each nasal cavity, once a day for 7 days. The behaviors such as nasal itching, sneezing, nasal discharge, asthma were carefully investigated. The behaviors were scaled from 1 to 3 scores and more than 5 scores in total were considered as a successful model. The eosinophils was counted under high magnification microscope (×400), and IL-6 and IL-10 were detected by ELISA Kits. Results The guinea pigs in experimental group after sensitizing and provocation developed frequent nasal itching, sneezing and rhinorrhea. The success rate of animal model in the experimental group was 60%. Compared with control group, eosinophil infiltration inexperimental group increased significantly (P < 0.05). The dead guinea pig in experimental group showed significant eosinophil infiltration in lung and bronchial mucosa compared to the control group seemingly like asthmatic inflammation. The experimental group had higher IL-6 level (185.41±9.57) ng/L, IL-10 level (99.97±12.71) ng/L than those in control group [IL-6 level (4.35±0.30) ng/L, IL-10 (4.45±0.31) ng/L] (P < 0.05, respectively). Conclusion The guinea pig model for AR is successfully established and lays the foundation for the following studies.%目的建立变应性鼻炎(allergic rhinitis,AR)豚鼠模型并检测白细胞介素6(interleukin 6,IL-6)和白细胞介素10(interleukin 10,IL-10).方法选用20只Hartley豚鼠,实验组和对照组各10只,随机分配.卵清蛋白(ovalbumin,OVA)作为致敏原,氢氧化铝作为佐剂.分两个阶段进行实验,第一阶段全身致敏,第二阶段鼻部激发.实验组OVA混悬液1 ml 腹腔注射,隔日1次,共7次;对照组0.9%氯化钠注射液1 ml腹腔注射.全身致敏后隔3 d用OVA溶液滴鼻,每侧鼻腔0.05 ml,1次/d,连续7 d;对照组用0.9%氯化钠注射液滴鼻.观察鼻痒(挠鼻)、喷嚏、清涕、哮喘等行为,用1~3分对四项行为评分,总分5分以上判定造模成功.高倍病理显微镜下计数嗜酸性粒细胞,用试剂盒检测黏膜组织中IL-6和IL-10.结果实验组豚鼠被致敏和激发后,频繁出现鼻痒(挠鼻)、喷嚏、清涕等行为,实验组造模成功率60%,实验组较对照组鼻黏膜嗜酸性粒细胞浸润明显增多(P<0.05).实验组死亡1只,其肺组织以及支气管黏膜较对照组嗜酸性粒细胞浸润明显.实验组豚鼠鼻黏膜组织IL-6水平为(185.41±9.57)ng/L,IL-10水平为(99.97±12.71)ng/L,较对照组IL-6水平(4.35±0.30)ng/L、IL-10水平(4.45±0.31)ng/L明显增高(P均<0.05).结论 AR豚鼠模型成功建立,为后续研究奠定了基础.【期刊名称】《解放军医学院学报》【年(卷),期】2017(038)004【总页数】4页(P333-336)【关键词】变应性鼻炎;动物模型;豚鼠;白细胞介素6;白细胞介素10【作者】栾兆磊;王雨农;王洪田【作者单位】解放军总医院耳鼻咽喉头颈外科,耳鼻咽喉研究所,北京 100853;解放军总医院耳鼻咽喉头颈外科,耳鼻咽喉研究所,北京 100853;解放军总医院耳鼻咽喉头颈外科,耳鼻咽喉研究所,北京 100853【正文语种】中文【中图分类】R765.21变应性鼻炎(allergic rhinitis,AR)是特异性个体接触变应原后主要由IgE介导的鼻黏膜的过敏性炎性反应疾病,常见症状是鼻痒、喷嚏、清涕、鼻塞[1]。
变应性鼻炎肾阳虚复合豚鼠模型筛选与评价潘利叶;马重阳;刘敏;李姝玉;于雪;范盎然;王旭;王淑艳;闫凯【摘要】目的:在卵清蛋白致敏变应性鼻炎豚鼠模型基础上,采用糖皮质激素、羟基脲、腺嘌呤3种不同阳虚诱导剂诱发,建立变应性鼻炎肾阳虚复合模型,以筛选建立理想而稳定的变应性鼻炎(Allergic Rhinitis,AR)病证结合动物模型。
方法:采用卵清蛋白(Ovalbumin,OVA)诱导建立变应性鼻炎豚鼠模型,同时给予糖皮质激素、羟基脲或腺嘌呤建立肾阳虚复合模型,观察动物宏观体征及死亡情况、局部过敏症状,酶联免疫吸附法(Enzyme-linked Immunosorbent Assay,ELISA)法测血清中 sIgE 和组胺含量,苏木精-伊红(Hematoxylin-eosin,HE)染色观察肾和睾丸组织形态学改变。
结果:糖皮质激素、羟基脲和腺嘌呤3种致肾阳虚药物均可使动物表现出肾阳虚症状及体征、体重下降并具有一定的致死率。
与空白组相比,糖皮质激素对肾脏和睾丸组织形态影响较小,羟基脲和腺嘌呤对肾脏和睾丸等形态结构影响较大。
结论:对比3个肾阳虚复合模型,羟基脲复合组模型比激素复合组和腺嘌呤复合组模型更稳定,且死亡率较低,较为理想。
不过变应性鼻炎病证结合动物模型的指标评价标准尚待进一步研究。
%Objective:To establish complex models with allergic rhinitis of kidney-yang-deficiency by three different kidney-Yang-deficiency inducers,glucocorticoid,hydroxyurea and adenine,based on guinea pig models of allergic rhinitis sensitized by ovalbu-min,for screening a reliable and ideal model of allergic rhinitis of kidney yang deficiencypattern.Methods:Guinea pig models of Allergic Rhinitis sensitized by ovalbumin were set and glucocorticoid,hydroxyurea or adenine was used to build the complex mod-els of allergic rhinitis with kidney-yangdeficiency.The macro signs,death and partial allergy symptoms of animals were observed, the serum sIgE and histamine were tested by ELISA (enzyme-linked immunosorbent assay)and the morphology change of kidney and testis tissue were observed by HE (hematoxylin-eosin)staining.Results:Three different Yang deficiency inducers,glucocor-ticoid,hydroxyurea and adenine,could lead to kidney-yang-deficiency symptoms and signs,weight loss,and cause certain death. Compared with the control group,it is found the affection on morphology of glucocorticoid to kidney and testis tissue was little, while which of hydroxyurea and adenine were great.Conclusion:By comparison of three different complex models with allergic rhinitis of kidney-yang deficiency,the model induced by hydroxyurea was more stable and suitable with lower death rate.More re-searches should be conducted for the evaluation criteria of the allergic rhinitis animal model.【期刊名称】《世界中医药》【年(卷),期】2016(011)012【总页数】6页(P2741-2746)【关键词】变应性鼻炎;肾阳虚;糖皮质激素;羟基脲;腺嘌呤【作者】潘利叶;马重阳;刘敏;李姝玉;于雪;范盎然;王旭;王淑艳;闫凯【作者单位】北京中医药大学基础医学院,100029,北京;北京中医药大学基础医学院,100029,北京;北京中医药大学基础医学院,100029,北京;北京中医药大学基础医学院,100029,北京;北京中医药大学基础医学院,100029,北京;北京中医药大学基础医学院,100029,北京;北京中医药大学基础医学院,100029,北京;北京中医药大学基础医学院,100029,北京;北京中医药大学附属东方医院,100078,北京【正文语种】中文【中图分类】R285.5目前最常见的变应性鼻炎动物模型是通过OVA致敏再诱发诱导致敏豚鼠血清IgE效价升高,从而出现相应鼻部过敏症状。
试验用Hartley豚鼠的饲养及滴鼻剂变应性鼻炎建模肖安菊;喻昕;尹美珍;卢彦秀【摘要】为探索试验用Hartley豚鼠的饲养及建立滴鼻剂变应性鼻炎(AR)模型的有效方法,本试验采用单因素试验,考察了试验动物种类、饲养方式、卵清蛋白(OVA)致敏剂量、时间对滴鼻剂AR建模的影响,观察空白组与模型组Hartley豚鼠过敏反应症状和鼻黏膜病理切片.结果显示,就滴鼻剂的AR试验而言,Hartley豚鼠是较好的试验动物;饲料为普通小鼠饲料+莴苣叶或油麦菜;OVA为致敏剂,基础致敏浓度为0.1~0.3mg/mL OVA,隔天腹腔注射1次,共7次;激发致敏浓度为2%,两侧鼻腔各10~30 μL,每天1次,6~9 d后与空白组相比,模型组Hartley豚鼠有明显的过敏反应症状和鼻黏膜病变.该建模方法简单经济,重现性好,可作为滴鼻剂AR建模的最佳方法.【期刊名称】《中国畜牧兽医》【年(卷),期】2015(042)005【总页数】5页(P1193-1197)【关键词】Hartley豚鼠;饲养;滴鼻剂;变应性鼻炎(AR);建模方法【作者】肖安菊;喻昕;尹美珍;卢彦秀【作者单位】湖北理工学院医学院,黄石435003;湖北理工学院医学院,黄石435003;湖北理工学院医学院,黄石435003;湖北理工学院医学院,黄石435003【正文语种】中文【中图分类】S858.91变应性鼻炎(allergic rhinitis,AR)以频繁发作的喷嚏、过量的鼻分泌物和显著鼻塞等症状为临床特征[1],是临床上常见的多发病,可发生在任何年龄段。
近年来,AR 的发病率在全球范围内呈明显上升趋势,它不仅可以导致患者一系列的呼吸道并发症,也严重影响着患者的生活质量、学习和工作效率等。
目前,临床仍以药物消除症状为主要治疗方法,AR 模型的建立对于治疗AR 的药物研究具有十分重要的意义。
冯纬纭等[2]综述了2000 年以来AR建模的相关文献,虽然很详尽,但试验动物、致敏剂浓度、使用剂量各不相同,后续试验者在建立滴鼻剂AR 模型仍感到无所适从。

变应性鼻炎大鼠模型建造刘建国1,杨 政2,刘月辉1(1.南昌大学第二附属医院耳鼻喉科,南昌330006; 2.宜丰县人民医院五官科,江西宜丰330600)摘要:目的 建立稳定的实验性变应性鼻炎(AR)SD 大鼠模型。
方法 将SD 大鼠雌雄各60只,随机分为实验组(n =60)和对照组(n =60)。
实验组经腹腔隔日1次注射卵清蛋白(O VA )变应原7次后,鼻腔滴入OV A 鼻内激发;对照组以生理盐水替代O VA 。
结果 实验组SD 大鼠均出现鼻痒、喷嚏、流清涕等变应性鼻炎的临床特征(评分>5分),鼻黏膜见大量的嗜酸性粒细胞、淋巴细胞浸润,粘膜水肿增厚、腺体增生、分泌旺盛,鼻黏膜表面纤毛破坏等组织形态学变化。
对照组SD 大鼠仅轻度抓鼻,且喷嚏少(评分<5分),鼻黏膜组织形态学均无实验组上述变化。
结论 本实验成功建立O VA 变应原致敏的变应性鼻炎鼠类模型,具有操作简单、重复性好的优点,为今后变应性鼻炎的病变研究提供了有效的方法及组织形态学依据。
