棘

Macrorckis with special reference to the cuticular spines and the reproductive system.

体棘的形状有多种多样的，但以宽阔形、凿形及尖刀形为最常见。

The cuticular spines vary in shape, but those with broad, chisel and lanceolate shape are among the commonest.

棘的最突出特点在于常呈纵裂状态，但很多又不完全分裂，特别是在口吸盘与腹吸盘间的。

The results showed that the ultrasonic extraction is a rather ideal method of extracting red P. tha fortuneana pigment. Cyanidin3glucoside can be hydrolysised to aglycon cyanidin under the conditions of 90℃, 9％HCl and 11min.Silica gel thinlayer chromatography with developping agent benzene∶ethyl acetate∶formic acid = 2∶2∶1 is better to separate cyanidin. Cyanidin is stable to heat and light, unstable to Zn2+ and Fe3+ and Cu2+, insensitive to Co2+ and Bi3+, befitting to acidic condition.

结果表明，超声提取法是提取火棘红色素的较理想方法；矢车菊素3葡萄糖苷在90℃和9％盐酸中水解11 min，可以顺利得到其苷元矢车菊素；以苯、乙酸乙酯、甲酸(2∶2∶1)为展开剂的硅胶薄层层析法分离矢车菊素的效果较好；矢车菊素对热和光较稳定，在酸性条件下稳定，对Co2+和Bi3+不敏感，对Zn2+、Fe3+、Cu2+不稳定。

Secondary glaucoma developed in 6 of 9 eyes subsequent to iris atrophy (4 eyes) or a cyclitic membrane (2 eyes), and 3 eyes underwent trabeculectomy.

在棘阿米巴角膜炎治疗过程中可发生白内障，同时可伴有前节炎症、虹膜萎缩和继发性青光眼。

They usually have daggerlike head spines and a flattened oval body with pointed fringe scales along the sides.

通常有匕首样的头棘，身体扁平呈卵形，两侧有尖形衬边鳞片。

They usually have daggerlike head spines and a flatten ed oval body with pointed fringe scales along the sides.

通常有匕首样的头棘，身体扁平呈卵形，两侧有尖形衬边鳞片。

Long-term modulation of spine density, but not number of primary dendrites, by BDNF was gated by cAMP.

研究表明，BDNF 对突触后树突棘密度的长时程作用也受cAMP 的门控调节，但是BDNF 对神经元一级树突数目的调节并不受cAMP 的调控。

A steroid alkaloid derived from skin secretions of the Phyllobates and Dendrobates genera of South American arrow-poison frogs.

蟾毒素从南美箭毒蛙属的phyllobates和树棘蛙的蛙皮中分泌的一种类固醇生物碱。

Results There were 52 cases (63%) of LA and 30 cases (37%) of MA, among which 49 cases (60%) presented with pyknotic nucleus of the basal keratinocytes above the amyloid in the upper dermis and 18 cases (22%) presented with pagetoid dyskeratosis cells among their prickle cells. More amyloid in LA and more severe incontinent of pigment in MA.

结果 82例患者中，52例(63%)为LA，30例(37%)为MA；有49例(60%)在淀粉样蛋白沉积上方基底细胞内出现核固缩现象；18例(22%)棘细胞层出现帕杰样角化不良细胞。

Focal acantholytic dyskeratosis with corps rounds and grains were the usual histopathological findings.

局限性棘层松解性角化不良及其产生的圆体和谷粒是最常见的组织病理学改变。

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％。
