Firstly , the V4 stock was purified three times by plaque formation. It's difficult to see clear plaques in CEF cells due to the avirulent characteristic , so we treated the V4 stock with trypsin and then allantoic Fluid and Mg2+ were added in the layer gel. In this case, we could see small plaques occasionally, but not stably.

本实验首先对实验室保存的V4株进行了三轮的蚀斑纯化，由于V4株属无毒株，其在CEF细胞中很难形成可见的蚀斑，因此我们采用了用胰酶处理V4病毒，并在上层胶中添加尿囊液及Mg2+，这样可以偶尔产生可见的蚀斑，但实验结果重复性很差。

Diagnostic characterisitics of adult were described. A mature nest is alveolate,and form big mound with (26.00±7.42) cm high,and (82.00±41.04) cm diameter on average of thirty random samples. which size far excess of other ants'.

蚁巢中可见蚁后、工蚁和兵蚁，生殖季节可见雌雄婚飞蚁；成熟蚁巢为蜂窝状，并突出地面形成高大蚁丘，随机测量30个，平均高(26.00±7.42)cm，平均直径(82.00±41.04)cm。

Grew on the normal temperature, it was shown that the deposits of calcium antimonate being the indicator for Ca(superscript 2+) localization mainly concentrated within the vacuoles and intercellular spaces and there was also some Ca(superscript 2+) deposits in cell walls. But when Garyota urens L. was treated by the temperature of 2℃ for 48 h, the level of Ca(superscript 2+) increased in cytoplasm and plasma membrane, but decreased in vacuoles and intercellular spaces considerably. At the same time, the ultrastructure of chloroplasts suffered from chilling: the membrane of chloroplasts had been damaged, the layer of thylakoids was exiguous and unclear, the photosynthetic rate decreased evidently. And when Garyota urens L. was treated by the temperature of 2℃ for 120 h, the deposits of Ca(superscript 2+) mainly concentrated within the cytoplasm, nucleus and plasma membrane and there was also some Ca(superscript 2+) deposits in vacuoles, and the ultrastructure of some cells was simultaneously damaged severely: Chloroplasts structure, vacuole membrane and nuclear membrane had been damaged fully, the structure within the cell had become unclear, and the cell only have respiration.

研究结果表明，未经低温处理的董棕幼苗叶肉细胞，焦锑酸钙沉淀颗粒大量出现在液泡和细胞间隙中，细胞壁中也可见少量沉淀，而细胞基质中则看不到焦锑酸钙沉淀；经2℃ 48 h低温处理后，细胞基质和细胞膜上焦锑酸钙沉淀增加，而液泡和细胞间隙中的焦锑酸钙沉淀则显著减少，并且超微结构已初步显示出寒害的特徵，叶绿体外膜部分破损，类囊体片层稀疏且排列不规则，光合速率明显下降等；经2℃ 120 h低温处理后，细胞间隙内的焦锑酸钙沉淀极少，有的也紧贴在细胞外壁上，而细胞基质和细胞膜上则分布有非常多的焦锑酸钙沉淀，在核基质和液泡中也可见到少量的焦锑酸钙沉淀，并且超微结构遭到了显著破坏，叶绿体结构完全被破坏，核膜与液泡膜严重破损，内部结构模糊，细胞只表现为呼吸作用，不进行光合作用。

Results The inpatients characterized with typical facial features, cutaneous basal cell naevus were obviously seen on the skin, palmar or plantar pits were viewed, bilamellar calcification of falx cerebri, bifid, fused or markedly splayed ribs were found, and histologically confirmed odontogenic keratocysts of jaw could be detected in most cases of BCNS.

The length of stenosis was 02~10cm and the Grade 1 stenosis was one renal artery,Grade 2 six renal arteries,and grade 3 three renal arteries.MSCTA showed 6 kidneys dwindled with average length 71cm,which was 15cm less than normal kidneys.One case was accompanied by wallthickening and cavitary stenosis of abdominal aorta.The locations and extent of stenosis in 6 cases by XRA and by MSCTA were identical.We found renal arterial stenosis only in 5 of 8 cases and 6 dwindled kidneys by DUS.

MSCTA尚可见6例肾缩小，平均长径为71cm，低于健肾15cm以上；1例伴有腹主动脉壁增厚，管腔狭窄，直径约10cm；6例行腹主动脉或选择性肾动脉造影者与MSCTA显示肾动脉狭窄部位和程度完全一致。8例行彩色多普勒超声检查者，亦可见6例肾缩小，但仅5例显示肾动脉狭窄，左侧2条，右侧3条。

The fundamental imaging features of osteosarcoma were showed bone destruction, periosteal reaction, neoplastic bone and soft-tissue mass. Among 49 cases examined by radiography, osteoblastic pattern sarcoma was found in 19 cases, osteolytic pattern sarcoma was found in 13 cases and mixed pattern sarcoma was found in 17 cases. The detection rates of bone destruction, periosteal reaction, soft-tissue mass, neoplastic bone and Codman triangle by radiography were respectively 61.2%, 95.9%, 71.4%, 73.5%and 27.7%. All 10 cases with CT scan were showed bone destruction, soft - tissue mass and neoplastic bone. The detection rates of periosteal reaction,憇ieve sign挶 and Codman triangle with CT scan were respectively 90%, 90% and 11%. The tiny neoplastic bone and"sieve sign"were showed sensitively by CT, but Codman triangle was showed by radiography superior to CT.32 cases with MRI scan presented the normal marrow was replaced by the tumor, which was showed low to intermediate signal intensity on T1-weighted images and promiscuity signal intensity on T2-weighted images. 7 cases presented hemorrhage and 24 cases presented necrosis.

骨肉瘤基本影像表现为骨质破坏、骨膜反应、瘤骨和软组织肿块。49例X线表现为成骨型19例，溶骨型13例，混合型17例；X线对骨质破坏、骨膜反应、软组织肿块、瘤骨和Codman三角的检出率分别为61.2%、95.9%、71.4%、73.5%和27.7%；10例CT表现均可见骨质破坏、软组织肿块及瘤骨，CT对骨膜反应、筛孔征和Codman三角的检出率为90%、90%和11%；CT对显示细小肿瘤骨和筛孔征最敏感，但对Codman三角的显示不如X线平片；32例MRI表现为骨髓腔内正常的骨髓高信号被肿瘤信号所取代，T1WI呈低～等信号，T2WI呈混杂信号，7例合并出血，24例中央坏死囊变，32例增强扫描均呈不均匀强化及瘤周可见水肿区。

Of the other 16 patients with ALS whose upper motor neurone signs were not so manifest (cases 6-21), high signal was seen in the corticospinal tract on T2-weighted images was seen in 11 (cases 6-12, 16-18 and 21); five (cases 6, 7, 11, 12 and 16) of these also showed high signal on the PD-weighted images.
