有囊的

Flowers unisexual. Male inflorescence precocious, elongate, pendulous, with numerous overlapping bracts; each bract usually subtending a small dichasium with 1-3 male flowers; stamens as many as and opposite sepals or, if sepals obsolete, then stamens of inflorescence to 20; filaments very short, connate or nearly so; anthers 2-loculed, thecae connate or separate, opening by longitudinal slits.

雄花序先有花，拉长，下垂，具多数重叠苞片；通常的每苞片对着一小的二歧聚伞花序具1-3雄花；同数的雄蕊和与萼片对生或，如果萼片废退，然后对20的花序的雄蕊；花丝非常短，合生或近合生； 2室的花药，合生的或分开的囊，以纵裂缝开阔的。

Cymes loosely many flowered, often conspicuously pedunculate, rarely in a dense verticillaster; corolla tube subequal or saccate, never short spurred on upper side near base; fruiting calyx with 5 subequal teeth or 2-lipped.

松弛多花的，经常显著有花序梗的聚伞花序，在一浓的轮状聚伞花序的很少；花冠筒近等长的或囊状，从未短的激励的上面边近基部；果期花萼具5近等长的齿或二唇形。

Some of these spores in the sporangium After the mitotic generated, such as clothes swimming algae spores, Rhizopus spores of the cyst, chlorella-like pro-spores, etc.; some spores in the sporangia produced in the future through meiosis, such as Ulva lactuca , kelp, to money, gourd moss, fern and so on.

其中有的孢子是在孢子囊中经过有丝分裂所产生的，如衣藻的游动孢子、根霉的孢囊孢子、小球藻的似亲孢子等；有的孢子是在孢子囊中经过减数分裂以后产生的，如石莼、海带、地钱、葫芦藓、蕨等。

Autosomal dominant polycystic kidney disease , one of the most common monogenetic human disorders, is characterized by the formation and progressive expansion of multiple cystic lesions, which compromise the function of normal renal parenchyma and lead to nearly 10％ of cases of end-stage renal failure in adults.

There are a few reports of features of internal hernia on CT. The largest series was a retrospective review of 17 patients by Blachar et al. They put forth the following CT findings in internal hernia:(1) evidence of small-bowel obstruction,(2) a cluster of small-bowel loops,(3) a saclike mass of small bowel,(4) crowding of mesenteric vessels, and (5) displacement of the mesenteric trunk.

有几篇关于腹内疝CT表现的报道，其中最大的研究是由Blachar等人对17例病例所作的回顾性分析，他们提出以下的腹内疝CT表现：（1）小肠梗阻的证据；（2）小肠肠管堆积；（3）小肠的囊性团块；（4）肠系膜血管拥挤；（5）肠系膜蒂的移位。

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有&盾状心皮&的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出&囊状心皮&的特点。

Materials and Methods The triphasic dynamic enhanced CT findings of 52 patients with renal cell carcinoma were reviewed.

资料与方法回顾性分析52例肾癌患者的三期动态CT扫描资料，对经手术病理证实的透明细胞癌、乳头状癌、嫌色细胞癌3种肾癌亚型图像进行双盲法对比分析，比较肿瘤的大小、强化程度与模式（均匀、不均匀及主要周边强化）、有无钙化、出血、坏死与囊变、肿瘤扩散及淋巴结转移等情况，同时结合患者的性别和年龄，分析3种亚型肾癌之间的影像学差异。

Here, we show that DEG5 and DEG8 form a hexamer in the thylakoid lumen and that recombinant DEG8 is proteolytically active toward both a model substrate and photodamaged D1 protein of photosystem II , producing 16-kD N-terminal and 18-kD C-terminal fragments.

我们研究发现在类囊体膜腔侧的DEG5和DEG8形成6聚体，重组的DEG8对于模式底物和光破坏了的光系统Ⅱ中的D1蛋白质都有蛋白酶解活性，可以将D1蛋白质剪切成N-末端16kD和C-末端18kD的片段。

In fact, BDNF potentiates intracellular Ca~(2+) release presynaptically and BDNF-induced TrkB activation also results in phosphorylation of synapsin I via mitoen activated protein kinase, which increases the number of synaptic vesicles available for release.

事实上，BDNF能促进突触前细胞内Ca~(2+)的释放，TrkB的激活也能通过有丝分裂活化蛋白激酶，引起突触素I的磷酸化，进而增加可释放的突触囊泡的数量。

objective to evaluate early signs of avascular necrosis of femoral head in adult by ct and to guide clinical treatment.methods the cases with suspicious diagnose of anfh were scaned in the both hip joints by x ray and ct to find the early signs of anfh with ct.results early signs of anfh using ct showed that, in 38 femoral heads 31 cases, there were radiate star shape of high density osteosclerosis of the trabeculae in 13 femoral head.twenty five femoral heads showed osteosclerosis and trabeculae structure disappearing and vague,incoordinately low ostedensity area and cyst change.there were fracture under the cartilage and light subsid in 5 cases.the cases in stage ⅰwere given decompression, while the pationtsresul in stageⅱand stageⅲ were given decompression and ostetransplant.conclusion ct results show that the sign of the high osteodensity and low osteodensity and cyst change can disply early anfh.

摘 要］目的：探讨成人股骨头缺血性坏死的早期ct征象并指导临床治疗。方法：对临床疑诊anfh的全部病例均行x线平片及ct检查，分析anfh的早期ct征象。结果：早期anfh的ct表现：31例38个股骨头，其中13个股骨头骨小梁呈放射状高密度的&星状征&，骨小梁境界清楚、锐利，属ⅰ期；25个股骨头表现为骨硬化，骨小梁结构消失、模糊不清，骨密度减低及囊性改变，属ⅱ期；并有5个股骨头在ⅱ期影像学改变基础上出现软骨下骨折及轻微塌陷，属ⅲ期。治疗结果：ⅰ期行钻孔髓内减压术，ⅱ、ⅲ期行钻孔减压植骨术。

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）。
