Evaluation of IEM103 in rabbit animal model.The evaluation was based on the control-challenge study (IEM101 as control). Rabbits were laparotomized, injecteded 10〓 cfu directly into proximal small bowel, and 28 days later, challenged with 0.25--2ug CT and 10〓-10〓 cfu 4 wild toxic strains with different biotypes and serotypes. Experimental group developed antitoxic and significant vibriocidal immune responses to vaccination, and could protect no less than 2ug CT and 10〓-10〓 cfu all wild strains challenge.

IEM103的免疫原性评价：经兔肠段结扎免疫〓cfu IEM103，7天后在外周血中可检测到外周淋巴细胞分泌性抗CT IgG，血清中可检测到抗CT抗体、杀弧菌抗体，P／N均≥2，且可持续至28天。28天后用0.25-2ug CT毒素，四种毒株滨-43，吴江-2，395，1119〓cfu菌量攻毒，实验组可保护至少2ug CT攻毒，而对照组可保护1ug以下CT攻毒，两组均可保护〓cfu四种毒株攻毒（以肠积液量≥1.0ml／cm为不保护判断标准）。

Small intestinal biopsies showed subepithelial collagen deposition with varying degrees of villous atrophy and varying numbers of intraepithelial lymphocytes. Four patients had previous biopsies showing enteropathic changes without collagen deposition. Seven cases were associated with collagenous colitis and 1 also had features of lymphocytic colitis. Three patients also had collagen deposition in gastric biopsies. One case was associated with lymphocytic gastritis. Celiac disease (CD, gluten-sensitive enteropathy) was documented in 4 patients. Five patients made a clinical improvement with combinations of a gluten-free diet and immunosuppressive therapy. Two patients died of complications of malnutrition and 1 of another illness. Clonal T-cell populations were identified in 5 of 6 cases tested. Four of these patients improved clinically after treatment but 1 has died. Collagenous sprue evolved on a background of CD in 4 cases. There was no history of CD in others and these cases may be the result of a biologic insult other than gluten sensitivity.

小肠活检表现为上皮下胶原沉积，绒毛萎缩程度不一，上皮内淋巴细胞浸润数量不等。4例患者以往曾做过活检，表现为其他肠病改变，并没有胶原沉积。7例患者合并胶原性结肠炎，且1例还有淋巴细胞性结肠炎的特征。3例患者胃活检也发现有胶原沉积。1例患者合并淋巴细胞性胃炎。4例患者有乳糜泻（CD，谷蛋白敏感性肠病）病史。5例患者经无麸质饮食和免疫抑制治疗后，临床症状有所改善。2例患者因营养不良合并另一种疾病而死亡。6例患者做了T细胞受体基因重排，其中5例发现有克隆性T细胞群，这5例中有4例治疗后临床症状加重，且1例死亡。4例患者在CD的基础上病发胶原性口炎性腹泻；其余患者无CD病史，他们的发病也许是生物源性损害，而非谷蛋白敏感。

Gastric glands distributed in fundic regions at 5-8 DAH. At this stage, supranuclear vacuoles occurred in the anterior intestine and eosinophilic granules occurred in the posterior intestine. The volume of the liver increased. Zymogen granules were seen in the exocrine pancreas and the langerhans was obvious. From 21 DAH to 33 DAH, the digestive system developed to be perfect.

孵出后5-8 d的仔鱼，胃基底部的粘膜上皮下出现胃腺，前肠粘膜层中出现核上空泡，后肠粘膜层中出现嗜曙红颗粒，肝脏体积增大，在胰脏的腺泡中出现大量的嗜酸性酶原颗粒，胰岛明显。

Methods From Feb 2006 to Jun 2006,188 hospitalized children in Shenzhen children s hospital, were collected deep tracheal aspirate at the time of hospitalization. The respiratory tract secretions were immediately sent for bacterial culture with 3 kinds of medium:ordinary medium, Hemophilus influenzae selective medium, Streptococcus penumoniae selective medium. Then we extracted the total nucleic acids from secretions, and detected Mycoplasma pneumoniae by single fluorescent quantitation PCR. Simultaneously, 14 respiratory tract pathogenic bacterium and Mycoplasma pneumoniae were detected by Target Enriched multiplex PCR. Amplification products were identified by the Luminex100 suspension array.

确诊为社区获得性肺炎的患儿188例，在入院当天采集深部呼吸道吸引物，用普通培养基和肺炎链球菌、流感嗜血杆菌选择性培养基进行细菌培养，然后提取深部呼吸道吸引物中病原体的DNA，采用荧光定量单PCR的方法检测肺炎支原体，并对同一标本采用靶序列富集多重PCR技术同时扩增肺炎链球菌、流感嗜血杆菌、金黄色葡萄球菌、肺炎克雷伯菌、大肠杆菌、嗜肺军团菌、铜绿假单胞菌、鲍曼氏不动杆菌、脑膜炎奈瑟氏菌、阴沟肠杆菌、奇异变形杆菌、化脓链球菌、粪肠球菌及屎肠球菌14种呼吸道病原菌和肺炎支原体的靶基因，扩增产物用Luminex100多功能悬浮点阵仪检测。

The specific PCR products of approximately 112bp in length was amplified from the other 10 strains of E.faecalis from lamb naturally infected with E.faecalis,lamb and mouse experimentally infected with E.faecalis by the PCR assay,but no any bands were amplified from Streptococcus equi subsp.equi,Streptococcus G,Streptococcus A,Staphylococcus aureus,Listeria monocytogenes from sheep,Mycoplasma ovipneumoniae and Brucella ovis.

在相同的时间下，粘虫中肠消化液蛋白酶活性比棉铃虫中肠消化液要高；在37℃条件下，棉铃虫中肠消化液经过30和60min将130kD的Bt CrylAc原毒素酶解为60kD的毒素，而粘虫中肠消化液经过30和60min对Bt CrylAc原毒素酶解作用，除得到60kD的毒素外还得到了40kD和分子量更小的蛋白。
