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。

The thylakoid of chloroplast was lost, the chloroplast was shrinked and composed into several discontinuous parts, which suggest that the function of chloroplast was destroyed;(2) the cell wall was thickened clearly, plasmolysis was found in most of Platymanas subcordiformis cells;(3) the number of mitochondria increased, some cristae of mitochondria were dissolved;(4) the number of vacuolar increased and the size of vacuolar was not uniform, the shape was deformed;(5) the nucleus was deformed and part of the nucleus membrane was dissolved;(6) Golgi dicytosomes accompanied with a loose arrangement of cisternae and the peripheral tips of the dictyosome cisternae are not especially swollen.

叶绿体内的类囊体缺失，叶绿体皱缩，叶绿体被分离成几个不连续的部分，说明叶绿体功能被破坏；(2)细胞壁明显增厚，细胞壁与细胞膜存在质壁分离现象；(3)线粒体数目增多，部分内嵴遭破坏；(4)液泡数目增多，大小不等，形状不规则；(5)细胞核变形，核膜部分解体；(6)UV-B处理的高尔基体有一个排列松弛的潴泡，潴泡的外围顶端并没有特别膨大。

Desmopressin can produce ELH and make the expression of AQP2 stronger in inner ears of guinea pigs. The result indicates that ELH may correlate to upregulation of AQP2, but the mechanism is not clear. There are two hypothesis which maybe explain the phenomena: the structural changes of AQP2 in ELS which inhibit the absorption of endolymph; or the relative deficiency of absorption of endolymph caused by the less increase of AQP2 in ELS than that of stria vascularis.

豚鼠腹腔注射去氨加压素能产生膜迷路积水，并使内耳中AQP2的表达增强，说明膜迷路积水可能与AQP2表达上调有关，其详细机理不清，目前有两种推测：内淋巴囊AQP2虽然表达增加，但构型改变，功能降低，减少了内淋巴的吸收；或者内淋巴囊中AQP2的增加少于血管纹AQP2的增加，内淋巴的吸收相对不足。

A very specialized feeding adaptation in zooplankton is that of the tadpolelike appendicularian who lives in a walnut -sizedballoon of mucus equipped with filters that capture and concentrate phytoplankton.

Whole-cellpatch-clamp technology demonstrated that VDPG (1g/L) had notsignificant effects on the delayed-rectified K~+ current, TTX-sensitive Na~+ current and high-voltage-activated Ca~(2+) current of rat dorsalroot ganglion cells. The fast transiet K~+ current of cottonbollworm dorsal DUM cells, the fast transiet K~+ current, Na~+ current andhigh-voltage-activated Ca~(2+) current of Periplaneta Americana dorsalunpaired median cells were also not significantly affected byVDPG at the same concentration. However, VDPG had significant effecton the fast transiet K~+ current of Pieris rapae. The VES had not significanteffects on the high-voltage-activated and low-voltage-activated Ca~(2+)current of rat DRG cells.

膜片钳电生理实验显示1g／L毒囊粗毒对蜚蠊DUM神经元的快瞬时钾电流、钠电流、高电压激活的钙电流，对棉铃虫快瞬时钾电流和大鼠DRG细胞延迟整流钾电流、TTX-S型钠电流、高电压激活的钙电流均无明显作用，却对菜青虫快瞬时钾电流有明显作用；电刺激粗毒对大鼠DRG细胞低电压和高电压激活的钙通道无明显作用。

But our study suggested that the innervation of knee joint had two layer groups : the superficial layer group and the profunda layer group.

浅层为皮神经，部分干较粗，容易形成皮神经瘤；深层可以分为伸膝肌支膝关节支组成的髌上区组，隐神经分支组成的内侧及髌下区组，腓总神经关节支组成的后外侧区组，月国丛神经组成的月国区组4组。4组神经在关节囊外分布有重叠交叉，但区域明确。
