Objective To investigate the genetic toxicity effect of tributyltin chloride on mouse embryonic limb bud cells.

目的 了解环境污染物氯化三丁基锡对小鼠胚胎肢芽细胞的遗传毒性。

DMBQ, ferulic acid and resorcin were effective chemical signal substances in the process of seed germination and haustorium formation of Cistanche deserticola. 4.The embryo is consist of 12 cells, the endosperm cell degraded so as to provide nutrition for the embryo development .As a result, germ tube differentiated from the embryo and came out through micropylar end, the small cell at the tip of the germ tube held the capacity of cleavage and the other cells grew big ,so the germ tube elongated .The anterior extremity of germ tube swelled to form haustorium under chemical substances treatment, the haustorium cell stained ,especially its portrait because of the lignification of the cells.

肉苁蓉种子的胚是由12个细胞紧密排列形成的圆球状胚，球形原胚分裂增殖的同时，胚乳细胞分解，为胚细胞的增殖提供营养，最终胚上分化出的芽管由珠孔端冒出，芽管前端细胞较小，具有旺盛的分裂能力，后部细胞体积增大，芽管逐渐伸长，在化学物质的诱导下，芽管由中部至前端细胞膨大分化出初生吸器，初生吸器呈帽子状，而这些细胞比其周围的细胞着色深，吸器纵向局部区域的番红染色加深，细胞高度木质化。

On admission the hemogram revealed 67% blast cells in the peripheral blood.

在住院时其周边血液分析发现67%之芽细胞。

Herein, we report a case of priapism in a 24-year-old male caused by CML with presentation of very high leukocytes count of 387800/mm^3 and 29% blast cells.

在此，我们报告一例二十四岁男性因慢性骨髓性白血病引起的阴茎异常勃起症，用非常高数目的白血球达387800/立方公厘并29%的胚芽细胞来表现。

We will try to find out the relationship of the enzyme activity in eyes with retinoblastoma in the future with this basis.

进一步的研究将以网膜芽细胞瘤病人为对象，研究乳酸脱氢酶在房水中的意义。

Four malignant GCTs (1 seminoma, 1 choriocarcinoma, and 2 yolk-sac tumors) have been treated in our hospital.

共有包括一位精细胞瘤、一位绒毛膜癌及两位卵黄囊瘤在内的四位恶性生殖芽细胞肿瘤的病人於本院治疗。

We observed the crystals under H-500 scanning electron microscope.Results The producing ways of tunica vasculosa microangiogenesis of rat's crystal:(1)single-directional germination;(2)bi-directional germination;(3)collagen and pericyte mediated germination;(4)angioblast inducted germination;(5)germ germinated.

结果 大鼠晶体血管膜血管发生方式：（1）单向芽生方式；（2）双向芽生方式；（3）胶原及周皮细胞介导的芽生方式；（4）血管母细胞诱导的芽生方式；（5）芽生芽的方式。

Wing bud differentiation initiated at the early 5th nymphal instar, during which the front wing bud cells in the macropterous proliferated much more rapidly than those in the brachypterous. The hinder wing buds of the brachypterous degeneratd at middle 5th instar and finally turned out to be very little wings.

在5龄初始时才发生翅芽发育的分化，之后，短翅型若虫的前翅芽细胞增殖速度明显慢于长翅型，到五龄末期，细胞数量积累明显少于长翅型，短翅型的后翅芽在5龄中期开始退化变短，羽化后变成一个退化的小翅。

For tumors which have been well sampled and exhibit (1) a microcystic pattern and regions with lobulated cellular masses with intervening, sometimes hyalinized fibrous stroma,(2) an absence of morphologic features enabling any other specific diagnosis in the sex cord-stromal category,(3) an absence of epithelial elements, and (4) an absence of teratomatous or other germ cell elements, we propose the designation microcystic stromal tumor.

我们很好地抽样调查了4例肿瘤，显示：（1）微囊样式和有时插入玻璃样变的纤维间质中的分叶状细胞团区，（2）能造成在性索间质这个大类中其他具体诊断的形态特征缺失，（3）上皮成分缺失，（4）畸胎或其他胚芽细胞成分缺失，我们提议定其名为微囊性间质瘤。

Compared with the nine cases of benign teratomas, the four malignant GCTs showed overwhelming male dominance, advanced symptoms at presentation, and poor outcome.

和其他九位成熟畸胎瘤病人比较，恶性生殖芽细胞肿瘤的病人有显著的男性病患倾向，明显的症状及较差的预后。

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％。
