The region between the circular brown band generated by cell lipid exosmosis and the band of the wound in the non-transgenic cotton Z35's leaves, is wider than that of the transgenic cotton T-34's leaves, and no micro-HR was found in Z35, the intensity of leaves wilting is much serious, by contrast, micro BR was found around the wound region within the transgenic cotton leaves inoculated with the pathogen, but the micro-HR was not found in the transgenic cotton treated with water and around wound region of non-transgenic cotton Z35 leaves which showed that there was micro-HR defence in transgenic hpa1xoo cotton.

棉花黄萎病菌侵染叶片后，非转基因棉花叶部伤口周围细胞无微过敏性反应，受病原菌侵染的叶片萎蔫程度较重；转hpa1xoo基因棉花叶部伤口周围细胞有微过敏反应，叶部刺伤处仅有较小的坏死斑，且不相连，发病较轻，而清水处理的转基因棉花与非转基因棉花叶片中伤口周围均无微过敏反应，说明病原菌侵染诱导转hpa1xoo基因棉花产生微过敏防御反应，转hpa1xoo基因棉花较非转基因棉花有较强的抗病性。

The first aim of this study is to clarify whether that polymorphisms of the genes that encode these enzymes associates with the TB drugs-induced adverse reactions. Furthermore, since tuberculosis patients are always administrated with multiple TB drugs, it is hard to distinguish which TB drug caused these adverse reactions.

本研究从结核药物过敏病患代谢酵素基因多型性方面探讨与结核药物过敏反应发生的相关性；此外，由於结核病患通常同时接受多种结核药物的治疗，导致难以判断是其中何种药物引起不良反应，本研究另一目标即为建立一T细胞体外培养系统，用於判断何种药物引起不良反应的产生。

ResultsPe Min Kam Wan, Lam Kam Sang Nasalin and Wo Chun Tong clearly inhibited PCA in mice and reduced histamine release from rat mast cells induced by compound 48/80. But,Sinuwell did not affect the PCA. In addition, the ethanol extracts from Senecio scandens, Selaginella tamariscina and Xanthium sibiricum significantly inhibited PCA in mice, but the extracts from Angelica dahurica, Magnolia liliflora and Cassia tora failed to affect it.

结果速效鼻敏感丸、林金生鼻敏清胶囊及和春堂鼻敏清片明显抑制小鼠异种被动皮肤过敏反应，减少compound 48/80诱导的组胺释放，而速效鼻敏素胶囊对被动皮肤过敏反应无明显影响；速效鼻敏感丸及和春堂鼻敏清片主要组成药物九里明、卷柏和苍耳子显著抑制小鼠异种被动皮肤过敏反应，而白芷、辛夷和决明子无明显作用。

It is necessary to strengthen safety education about drug allergy for nurses,including the meaning of drug allergy,recognizing that each drug and each medication route may has allergic reaction and drug allergy test is not the only standard to estimate drug allergy,abiding by nursing technique regulations strictly,guaranteeing the quality of drug allergy test,monitoring drug allergic reactions,recognizing the high incide...

必须对护士加强药物过敏的安全教育；不断学习和认识药物过敏的深刻意义，每一种药物和给药途径均可能发生过敏反应，药物过敏试验不是判断药物过敏的唯一标准，应走出药物过敏的误区；严格遵守护理技术操作规程，把好药物过敏试验质量关；密切观察药物过敏反应，掌握药物高度过敏反应发生的时间，早期发现不典型过敏性休克的症状；熟练掌握过敏性休克的抢救规程，病人对药物过敏的相关内容应有醒目标志。

Methods 55 patients were treated with pelvic cavity fourfold radiography and conventional check before iodic allergic experiment.

方法选择门诊患者55例，均行四重造影检查，检查前常规行碘过敏试验阴性52例，用复方泛影葡胺为造影剂；用非离子型碘造影剂碘海醇为造影剂，观察造影过程中患者过敏反应，分析碘过敏反应的机制。

Allergists and immunologists don't understand why these foods cause a reaction, nor do they know exactly what leads someone to develop a food allergy.

过敏反应学家和免疫学家都不能理解为什么这些食物会引起这种反应，也不知道真正导致一个发生食物过敏反应的是什么东西。

Think of allergies as the body's way of fighting unwanted guests. The trouble starts when allergens, such as pollen, certain foods, or animal dander invade the mucous membranes of the eyes and throat, this triggers the body's antibodies to fight the invaders, causing a release of histamines. The body's reaction to the allergens is often excessive, leading to sneezing, shortness of breath or itching. It's these reactions that wear you down, especially when they keep you from sleeping.

过敏反应其实是机体抵抗外来客的一种反应方式，当过敏原如花粉、某些食物或动物皮屑等通过眼睛和喉咙的粘膜入侵机体时，机体就会产生抗体释放组织胺来抵御入侵者，这种反应常常过度从而导致出现打喷嚏、瘙痒甚至气急等症状的发生，这些反应症状会使你感到疲劳、特别会导致睡眠不好。
