核分裂

Holmes' outburst could be due to a sudden exposure of fresh cometary ice or even the breakup of the comet nucleus.

Holmes彗星爆发的原因可能是彗冰的突然暴露，甚至可能是彗核分裂。

The enteropathy shown here has loss of crypts, increased mitotic activity, loss of brush border, and infiltration with lymphocytes and plasma cells (B-cells sensitized to gliaden ).

肠下垂显示肠壁变薄，核分裂像增多，刷状缘减少，淋巴细胞和浆细胞浸润增多（ B 细胞对麸质较为敏感）。

Methods:33 cases were classified asⅠ,Ⅱ,Ⅲ according to heteromorphic degree of interstitial cells,nuclear fission and special interstitial ingredient.

对 33 例经病理证实的乳腺叶状囊肉瘤，根据间质细胞异形程度和核分裂数、是否浸润、是否含有特殊间质成分进行分级。

Innocuousness tumor group have no manifest bleeding and necrosis. Cells have no heteromorphism and less caryocinesia.

良性组肿瘤无明显出血、坏死，细胞无异型性，核分裂少见。

Malignancy tumor group are abundance of cellulars and haemorrhage 、necrosis 、heteromorphism、caryocinesia are manifest.

恶性组肿瘤组可见出血坏死，细胞丰富，明显异型性，核分裂多见。

All other LMSs had ≥35 mitoses/50 HPFs.

其他15例的核分裂像≥35/50个HPFs。

One of these tumors, a 16 cm diverticular tumor, had mitotic activity of only 1/50 HPFs, and this tumor recurred 4 times.

其中1例呈憩室性，16cm大小，其核分裂像只有1/50个HPFs，但这例却复发了4次。

Methods Immunohistochemical SP method was used to detected c-erbB-2 expression,lymph node metastasis and karyokinesis of cancer cells in breast infiltrating ductal carcinoma.

结果c-erbB-2阳性表达主要分布在肿瘤细胞的胞膜上；随着c-erbB-2表达强度的降低，肿瘤淋巴结转移率呈减少的趋势；肿瘤组织中细胞的核分裂数目随着c-erbB-2的表达强度增加而增多。

Results Differentiation,invasion degree of lymph cell,tumor thickness,the number of capillary and pathological karyokinesis were not related with cervical lymph node spreading.

结果 分化程度、淋巴细胞浸润程度、浸润厚度、微血管数、病理核分裂数与区域淋巴结转移无关；肿瘤大小与区域淋巴结转移有关。

In contract, the tumor tissue of control group kept morphology, tumor nodules composed of undifferentiated carcinoma, and some karyokinesis could be seen, some spotty necrosis were found occasionally in where the structure among tumor cells were loose associated very slight inflammatory response; At the 21 days after injected AdCMVIL-12, the tumor boundary of AdCMVIL-12-Ⅰ group were clear and felt hard by touch, section showed grey.

同期的对照组绝大多数肿瘤细胞形态完好，排列紧密，由大量未分化的肿瘤细胞组成并可见多个核分裂像，偶尔可见散在的点状坏死灶，瘤细胞之间结构松散，炎症反应很轻；AdCMVIL-12注射后第21天时，AdCMVIL-12-Ⅰ组的肿瘤组织经手摸感觉瘤体境界清楚、发硬，切面呈灰白色。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
