Children are routinely immunised against Hib, but before the vaccination was introduced in the UK, epiglottitis was most common among children aged between two and seven Its very rare for adults to get epiglottitis, but you are more likely to get it if your immune system doesnt work properly, for example if you have had chemotherapy or if you have HIV.

儿童是例行免疫针对Hib的，但前接种疫苗介绍了在英国，会厌炎是最常见的儿童年龄介乎二和七it s非常罕见的成人获得会厌炎，但你越有可能得到它如果您的免疫系统doesn 吨正常工作，例如，如果您有化疗或如果您有艾滋病毒。

Methods 1. The mice were divided into control and 3 Ganodermalucidum spores oil groups (at low, moderate and high doses), orally given forconsecutive 30 days. The body, spleen, thymus weight were observed, study on theeffect of the drug on the cellular immune function by proliferation and transformationof spleen lymphocytes test; study on the effect of the drug on the humoral immunefunction of mice by serum erythrocytolysin test; study on the effect of the drug on themononuclear macrophage function by carbon clearance and neutral red test.

实验方法 1设玉米油对照组和低、中、高三个灵芝孢子油剂量组，连续灌胃30天后观察小鼠体重、胸腺、脾脏重量指数；采用吞噬中性红和碳廓清实验测定对小鼠单核-巨噬细胞功能的影响；血清溶血素实验测定对小鼠体液免疫功能的影响；ConA诱导脾淋巴细胞转化实验测定对小鼠细胞免疫功能的影响；MTT法测定对小鼠NK细胞杀伤活性、脾细胞产生TNF-α和IL-2含量的影响。

The results of study show:1. White pulp and red pulp in parenchyma of spleen of embryo can be obviously discerned after 18 days. Periarterial lymphoid sheath and ellipsoid periarterial lymphoid sheath also can be obviously discerned in spleen of 4 days chicken. T, B lymphocytes in appendix basement of embryo emerge after 20 days. It is the initial shape of cecal tonsil. Crypt structure of conjunction of esophago and stomachus glandularis form obviously at 4 days. It is the initial shape of esophago tonsil. The germinal center firstly emerges in these three organs at 14 days. With the increase of day age, the characteristic structure peripheral immune organs gradually develop mature. Spleen achieve mature at 21 days and cecal tonsil at 35 days.2. IgM~+ and IgA~+ cells in spleen of embryo emerge at 15 days. IgG~+ cell, CD3~+ and CD8~+T lymphocytes of embryo emerge at 20 days. CD3~+, CD8~+ and IgM~+ cells in cecal tonsil of embryo emerge at 20 days. However CD4~+, IgG~+ and IgA~+ cells all emerge in 1 day age chicken out of crust. CD3~+, CD4~+, CD8~+, IgM~+ and IgG~+ cells in esophago tonsil of embryo all emerge at 20 days. However IgA~+ cells emerge in 1 day age chicken out of crust.3. The amount of T, B lymphocytes in peripheral immune organs increase follow with the increase of day age, and hold an upgrade tendency. The amount of T, B lymphocytes in spleen achieved stabilization at 21 days, and in tonsil of esophago and appendix at 35 days.

研究结果表明：1、在组织结构方面，脾脏实质内的白髓与红髓在胚胎18日龄后明显可辨，4日龄雏鸡脾脏中形成明显可辨的动脉周围淋巴鞘和椭球周围淋巴鞘；盲肠基部T、B淋巴细胞在胚胎20日龄时开始出现，即初步形成盲肠扁桃体；食管与腺胃结合处在4日龄时形成明显的隐窝结构，即食管扁桃体初步形成；14日龄时，三种器官中首次出现生发中心；随着日龄的增长，外周免疫器官特征结构不断发育成熟，脾脏在21日龄时达到成熟水平，盲肠扁桃体和食管扁桃体在35日龄时达到成熟水平。2、在T、B淋巴细胞出现时间方面，脾脏中IgM~+和IgA~+细胞在胚胎15日龄时开始出现，IgG~+细胞、CD3~+和CD8~+T淋巴细胞在胚胎18日龄时出现，CD4~+细胞在胚胎20日龄时出现；盲肠扁桃体中CD3~+、CD8~+和IgM~+细胞在胚胎20日龄时开始出现，而CD4~+、IgG~+和IgA~+细胞均在雏鸡出壳后1日龄时出现；食管扁桃体中CD3~+、CD4~+、CD8~+、IgM~+和IgG~+细胞均在胚胎20日龄时开始出现，而IgA~+细胞则在雏鸡出壳后1日龄时出现。3、在T、B淋巴细胞数量变化方面，外周免疫器官中T、B淋巴细胞的数量随日龄增长，整体均呈上升趋势。

Each group was further divided into 4 sub-groups according to the different stage of the estrous cycle.

The immune system identifies in the process of exertive immunity function is an important premise.

免疫系统在发挥免疫功能的过程中，识别是个重要的前提。

Exogenic transplanted MSCs were not immune rejected,and did not initiate specific immune response during the second transplant.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
