| 1 | 卵白蛋白经鼻致敏建立变应性鼻炎动物模型显示文摘目的 建立豚鼠变应性鼻炎动物模型,并对其速发和迟发症状、病理学和免疫学指标进行观察。方法 实验豚鼠分为模型组、治疗组和阴性对照组,每组 12只。阴性对照组未予致敏和激发,模型组和地氯雷他定治疗组由卵白蛋白经鼻反复致敏和激发后,对其喷嚏、抓鼻、鼻腔分泌物及鼻塞做动态症状学观察;通过被动皮肤过敏实验,测定血清IgG1和IgE水平;计量鼻腔灌洗液中白细胞总数、嗜酸粒细胞数及组胺水平;并且观察鼻腔组织的病理改变。结果 经抗原激发后,模型组出现典型的喷嚏、抓鼻、鼻塞和分泌物增多的表现;鼻腔灌洗液中炎性细胞和嗜酸粒细胞增多、组胺水平升高、血清IgG1和IgE滴度升高。上述表现与阴性对照组比较差异有统计学意义 (P<0.05或<0.01),也比治疗组明显增高(P<0.05或<0.01)。模型组的鼻腔黏膜嗜酸粒细胞浸润明显,小血管扩张,杯状细胞扩大。此外,模型组还可观察到迟发相鼻塞。结论 此模型能良好地反映变应性鼻炎的各项表现,方法简易,建模时间短,亦能观察迟发性鼻塞,且对组胺H1受体拮抗剂的治疗反应明确,是研究变应性鼻炎的良好工具。 | 赵宇 C.Andrew vanHasselt 吴港生 黄约爱 梁传余 梁秉中 | 2005 | 中华耳鼻咽喉头颈外科杂志2005，40，3： | 51 |
| 2 | 人肥大细胞系白细胞介素4的产生及药物对其的影响显示文摘目的了解人肥大细胞系(humanmastcellline,HMC1)在佛波醇酯(phorbol12myristate13acetate,PMA)+钙离子通道(A23187)激发下能否产生白介素(Interleukin,IL)4,并且观察布地奈得、地氯雷他定和地塞米松等药物对IL4的产生和表达的影响。方法HMC1在10-6~10-10mol/L浓度的药物中孵育1h后,以25ng/mlPMA+25×10-7mol/LA23187激发细胞因子生成,再分别孵育6、12或24h,提取上清液,采用酶联免疫吸附法(enzymelinkedimmunosorbentassays,ELISA)测定IL4水平,并采用半定量逆转录聚合酶链反应(reversetranscriptionpolymerasechainreaction,RTPCR)观察药物对IL4mRNA表达水平的影响。结果HMC1在激发后可产生IL4,IL4mRNA的表达也很明显。布地奈得、地氯雷他定和地塞米松在各时间点和浓度下,均对HMC1IL4的产生有明显的抑制作用(同未加药物的对照组比较,P值均<005),抑制率在(361±40)%到(679±38)%之间。布地奈得和地塞米松对IL4mRNA的表达无抑制作用,而地氯雷他定则能明显抑制IL4mRNA的表达水平。结论HMC1经激发可表达和产生IL4,布地奈得、地氯雷他定和地塞米松能显著抑制IL4的产生,地氯雷他定还能抑制IL4mRNA的表达。 | 赵宇 C.Andrew van Hasselt 吴港生 黄约爱 梁传余 梁秉中 | 2005 | 中华耳鼻咽喉头颈外科杂志2005，40，2： | 3 |

| 4 | Inaccuracies in the history of a well-known introduction:a case study of the Australian House Sparrow(Passer domesticus)显示文摘Background:Modern ecosystems contain many invasive species as a result of the activity of acclimatisation societies that operated in the second half of the nineteenth century,and these species provide good opportunities for studying invasion biology.However,to gain insight into the ecological and genetic mechanisms that determine the rate of colonization and adaptation to new environments,we need a good understanding of the history of the introduced species,and a knowledge of the source population,timing,and number of individuals introduced is particularly important.However,any inaccuracies in the history of an introduction will affect subsequent assumptions and conclusions.Methods:Focusing on a single well-known species,the House Sparrow(Passer domesticus),we have documented the introduction into Australia using primary sources(e.g.acclimatisation records and newspaper articles).Results:Our revised history differs in a number of significant ways from previous accounts.Our evidence indicates that the House Sparrow was not solely introduced from source populations in England but also from Germany and most strikingly also from India—with the latter birds belonging to a different race.We also clarify the distinction between the number released and the number of founders,due to pre-release captive breeding programs,as well as identifying inaccuracies in a couple of well-cited sources with respect to the range expansion of the introduced populations.Conclusions:Our work suggests that caution is required for those studying introductions using the key sources of historical information and ideally should review original sources of information to verify the accuracy of published accounts. | Samuel C.Andrew Simon C.Griffith | 2016 | Chinese Birds2016，，2： | 0 |
