Due to the deficiency of cyclin B1 and 〓, spermatogonia and pachytene/diplotene primary spermatocytes in contralateral cryptorchid testis were unable to form MPF, and therefore, they could not accomplish their nuclear division, and became arrested at the transition stage from mitosis to meiosis (G2/M phase). We also found that testosterone could regulate the cyclin B1 expression in spermatogenic cells.

由于cyclin B1和〓的缺失，粗线期/双线期初级精母细胞中的MPF无望形成，从而导致生精细胞分裂停滞在由有丝分裂向减数分裂过渡的G2/M相；（5）睾酮可在翻译水平上调控阴囊内睾丸生精细胞cyclin B1蛋白的表达。

So it is important to research the activity disciplinarian of Ca~(2+) inside and outside cellular.

荧光显微技术由于具有响应时间短、对细胞无毒害作用等特点，而成为测量活细胞内游离钙浓度的主要方法。

Results The optimum combination was 10μmol/L β-asarone +3μmol/L eugenol, which can decrease the concentration of intracellular Ca(superscript 2+), inhibit the production of NO and increase the survival rate of PC12 cells.

结果β-细辛醚10μmol/L+丁香酚3μmol/L组合能有效减少细胞内Ca(上标 2+)浓度，抑制NO的产生，提高细胞存活率。

Mycorrhizal fungi enter the velamen and exodermis through root hair, invade the cortical tissue by the exodermal passage cells and then form pelotons.

独花兰具有典型的兰科植物菌根构造，在光学显微镜下可以观察到菌根真菌从根毛进入根被和外皮层，通过通道细胞侵入到皮层薄壁组织，在皮层薄壁细胞内形成菌丝团。

Intracellular pH and membrane potentialof glomus cells of both the groups were simultaneously measured with pH-sensitive and conventional microelectrodes.

球细胞的细胞内pHpH_(i和膜电位分别用H~选择性微电级和常规微电极同时测量。

Rats were killed after different weeks(0,1,2,4,8,12,15,17,19,20 and 24 respectively). Their organs were taken to observe the kinetic change of selenium concentration, the activities of intracellular glutathione peroxidase,extracellular glutathione peroxidase, and phospholipid hydroperoxide glutathione peroxidase in different organs.

于0、1、2、4、6、8、12、15、17、19、20和24周时处死大鼠取其组织，分别对各种组织中的硒、细胞内谷胱甘肽过氧化物酶、细胞外谷胱甘肽过氧化物酶、磷脂氢谷胱甘肽过氧化物酶、Ⅰ型脱碘酶和Ⅱ型脱碘酶活性进行动态观察。

The results of RT-PCR indicated that the HGV genes can be transcripted in blood monocytes and hepatocytes.The conventional pathological observation suggested that the transgenic mice had the cloudy swelling,steatosis,hydropic change and inflammatory cellular infiltration.However,serum ATL level showed no significant difference between transgenic and normal mice.

RT-PCR的结果显示，外源基因可在founder小鼠及F1代小鼠的血液有核细胞及肝细胞内转录；组织病理学检查显示，某些转基因小鼠的肝细胞出现了水样变、脂肪变性及轻微炎性反应等病理学改变，但与同一品系的正常小鼠相比，转基因小鼠血清转氨酶无明显升高。

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）。
