Methods The staining status was compared of MMP 2, MMP 9, TIMP 2 and TIMP 1 in cryostat sections of tumor tissue in 35 NB patients by immunohistochemistry.

应用免疫组化SABC法检测 35例神经母细胞瘤标本中MMP 2、MMP 9及TIMP 2、TIMP 1的表达情况，并比较其在无转移、局部转移及远处转移患者肿瘤组织中的表达程度。

We previously showed that lymphoblastoid cells grown in the presence of an indirect methyltransferase inhibitor, adenosine dialdehyde, accumulated high level of hypomethylated protein substrates.

我们先前的资料显示将淋巴母细胞养在含AdOx (一种间接的甲基转移抑制剂)的培养基中，可获得大量低甲基化的受质。

Objective: To investigate the efficiency of vitrification of immature oocytes to expand the field of gamete cryopreservation.

目的：探讨玻璃化冷冻未成熟卵母细胞的有效性。

Methods Twenty-three cases of neuroblastoma with bone marrow metastasis were reviewed and studied by light microscopy and immunohistochemical staining.

对23例神经母细胞瘤骨髓转移的临床病理资料进行分析，并做光镜观察及免疫组化染色。

Objective To explore the feasibility of vitrification of mouse maturation oocytes, using a close-carrier.

目的 探讨封闭式玻璃化冷冻载体冻存小鼠卵母细胞的可行性。

CCSK is a rare type of renal neoplasm in childhood and its diagnosis relies mainly on histopathology and immunohistochemistry. It is important to be familiar with the morphological variants of CCSK to avoid confusion with other similar lesions, such as Wilm's tumor, congenital mesoblastic nephroma, malignant rhabdoid tumor of kidney, primitive neuroectodermal tumor.

CCSK是一种罕见的儿童期恶性肾肿瘤，诊断主要依靠组织病理学和免疫组化，熟悉其形态学变异有利于与其它类似病变如肾母细胞瘤、先天性中胚叶肾瘤、肾恶性横纹肌样瘤、原始神经外胚叶肿瘤等鉴别。

Results There were three morphological types of BM metastasis of NB, microinvasive, moderately invasive and diffusely invasive pattern. CgA/NSE immunohistochemical staining was needed fur confirming the metastatic neuroblastic cells in microinvasion.

结果 神经母细胞瘤骨髓转移表现为微小浸润、中度浸润和弥漫浸润三种形式，主要根据骨髓造血组织与肿瘤成分的比例和分布而定，其中微小浸润常需行CgA/NSE免疫组化染色辅助诊断。

All results above indicated that:The expression of ERβand p-ERβin mouse ovary at oestrous cycle and in early gestational period changed regularly, it showed that ERβand p-ERβhad important effects to ovaries development, ovarian follicles groth, oocyte maturation and form corepus luteum in female mouse ovary during oestrous cycle and in early gestational period.

以上结果表明：ERβ及其磷酸化形式——p-ERβ在小鼠发情周期以及妊娠早期卵巢中表达有规律性的变化，揭示ERβ与p-ERβ在雌性小鼠发情周期及妊娠早期，对卵巢发育、卵泡生长、卵母细胞成熟和黄体形成有重要的作用。

These abnormal cells became dramatically vacuolated and hereafter disintegrated completely at later stage.

这类异常的小孢子母细胞在随后的发育中逐渐液泡化并最终解体。

Hytivus. Although chromosome number of all materials studied was counted to be 2n = 38, the difference in meiotic behaviors between individuals of first selfed progenies were observed, which indicated the difference in the degree of diploidization.

虽然染色体记数的结果表明所有单株的染色体数目都为38条，但是花粉母细胞的减数分裂行为在单株间的细小差异也被观察到了，这表明各单株间存在较小的二倍化程度的差异。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
