After treating with 1% pancreatin,lecithinase C and 10% aether,the allantoic fluid of this virus could agglutinate the erythrocytes of chicken,sheep,human being,mouse and rabbit,while the allantoic fluid of this virus without this treatment had no this agglutinative activity.

经浓度1%胰酶、卵磷脂酶C和10%乙醚处理后，该病毒尿囊液可以凝集鸡、绵羊、人、小鼠和兔的红细胞，而未处理的病毒尿囊液则无此凝集活性。

Finally, the guideline for efficiently preparing core-shell structured capsule carrier was tentatively proposed.The cationic, neutral and anionic polysaccharides were separately acted as the liquid core of biomimetic capsule by mimicking the component and function of cell sap. It was found that the electrostatic repulsion interaction between the polysaccharide core and the enzyme enhanced the enzyme activity and stability.

首先，模仿细胞液的成分和功能选用三种具有不同电性的多糖(羧甲基纤维素钠、甲基纤维素和羧甲基壳聚糖钠)作为仿生微囊的液核，经比较可知，与酶分子具有静电排斥作用的多糖更有利于酶构象、活力的维持和酶稳定性的提高；然后，模仿细胞膜的结构和功能构建仿生微囊的壳膜。

Lysis solutions from imported and domestic genomic DNA purification kits,and 2% Trition X-100 and 5%guanidinium isothiocyanate were added into the oocysts,followed by different combining forms of freeze-thawing,proteinase K and sonication.Real-time PCR was used to determine the copies of Cryptosporidium oocyst wall protein gene.HCT-8 cells were infected by C.andersoni oocysts.Real-time PCR was used to determine the enhancement effect of fetal calf serum,glucose,ascorbic acid,folic acid,calcium pantothenate and insulin while added into RPMI-1640 medium.

Results: MR demonstrated capsule wall and papillary solid lesions in one case with cystic and solid lesions of hepatobiliary cystadenoma. Poly cystic form tan if different sine in sew case, capsule wall and septation was thick, part of capsule wall was obviously thickened and nodes form, intrahepatic bile duct was dilated, large poly-antrum cystic keen form structure in one case, capsule wall and septation were smooth, part of capsule wall was uniformly thicken, capsule wall, septation, mural nodus form and solid lesions in three cases wee all slightly hyperintense on T2WI and slightly hypointense on T1WI. Part of cyst fluid was hypointense on T2WI the diameter if tumor ranged from 3.4cm to 13.5cm. Part of capsule wall, septation, solid lesions and mural nodus west obviously enhanced in arterial phase in three cases, the extent of enhancement showed a little degrade in port vein phase, balance phase and delay phase, but dense to liver parenchyma at synchronization.

结果：3例肝内胆管囊腺瘤中1例呈囊实性结构，可见囊壁及乳头状实性肿块；1例为多个大小不等的多房囊状结构，囊壁及分隔光滑，囊壁局部明显增厚，有壁结节，周围见轻度的肝内胆管扩张；1例为巨大的多房囊状结构，囊壁及分隔光滑，局部均匀增厚；3例中的囊壁、分隔、壁结节及实性部分均呈T2WI稍高信号、T1WI稍低信号，囊内液性部分均呈T2WI高信号、T1WI低信号；肿瘤瘤体大小径线范围3.4~13.5cm.3例肝内胆管囊腺瘤中囊壁、分隔、实性肿块和壁结节动脉期均明显强化，门脉期、平衡期及延迟期强化程度略减低，强化程度均高于同期肝实质。

In ACC, NGF,TrkA and p75 mainly existed in cells of duct-like, cribriform and mass-like structures.According to the optical density scanning of immunohistochemistric stain of NGF and TrkA in salivary gland and tumor tissues and quantification analysis, it was shown that the average optical density of NGF and TrkA increased in order of salivary gland tissues around neoplasm, mucoepidermiod carcinoma, and adenoid cystic carcinoma.

2叫 吉林大学硕士学位论文通过对NGF和TrkA在涎腺组织和涎腺肿瘤中的免疫组织化学染色结果进行光密度扫描，对所测平均光密度定量分析，结果显示：NGF和TrkA平均光密度值按照肿瘤周围涎腺组织、豁液表皮样癌和腺样囊性癌依次升高，统计学分析在各组间均有极显著差异(P.01)，表明NGF和TrkA通过自分泌机制调控涎腺腺样囊性癌和豁液表皮样癌的生长与增殖，通过旁分泌机制参与涎腺腺样囊性癌向神经周围的浸润。

Department of Neurosurgery, Shenzhen Second People's Hospital, Shenzhen Guangdong 518035, ChinaAbstract: Objective: To study the curative effect of stereotactic intracystic irradiation of treatment of cystic and cystsolid craniopharyngioma guided by CT or MRI. Methods: After cystic liquid was absorbed, colloid chromic phosphate was injected in the cystic part of the patients with cystic or cystsolid craniopharyngioma under CT or MRI.

Results: 22 cases of inflammatory pseudotumor, and all the dissociated edges being sharp, including 9 cases involving tear gland, 7 cases surrounding the eyeball, 2 cases showing the optic nerve and extraocular muscles thicken, and 4 cases showing several extraocular muscles diffuse thicken. 4 cases were granulomatous inflammation filling up the orbit with soft tissue. One case was the chronic inflammation of the lacrimal sac showing a cystoid lump in the area of the lacrimal sac. One case was the chronic inflammation around the lacrimal sac showing a small lump with a low denstiy in its center in the area of the lacrimal sac. One case was orbital cellulitis showing the density of the right part in the orbit outside the eyeball becoming higher, and having not a edge.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
