The results showed that the volume density of mitochondriumand mitochondrial intermembrane crack increased according to ischemic time extension;The volume density ofmitochondrial crista decreased according to ischemic time extension;prominent defference occured after 45 min-utes of ischemia,The practice demonstrates that image analysis instrument has marked pre...

结果显示：线粒体和线粒体外室的体密度随缺血时间延长而加大，线粒体嵴的体密度随缺血时间的延长而减少，缺血45min以后即和正常对照有显著性差别。实践证明，图像分析仪在定量超微结构的变化上，具有高度的精确性，故可早期发现病变。

METHODS By using immunohistochemical method,the expressions of PKCβⅠ and PKCγwere examined in ginea pig macula utriculus,macula sacculus and crista ampullaris.Theγ-32 P was used as a tracer to measure the activity of PKC in vestibular terminal organs.

采用免疫细胞化学法观察椭圆囊斑、球囊斑和壶腹嵴PKCβⅠ，Ⅱ，γ亚型的表达；应用γ-32 P示踪检测前庭终器PKC活性的变化。

Objective To further understand the intracellular calcium mobilization features of the isolated ampullate crista vestibular hair cells and ATP effects on intracellular free calcium concentration(［Ca2+］i) in VHCs of the guinea pig.

目的 探讨离体前庭毛细胞（vestibular hair cells，VHC）去极化时细胞内钙离子活动特征及内耳活性物质ATP对离体VHC内钙离子浓度的影响及其机制。

Results: In all 13 patients, non-contact mapping showed AFLs confined to the RA with the cycle length (230 ±20 ms). 6 patients presented single-loop re-entry circulating around the central obstacle in the anterolateral wall through the channel between the CO and the crista terminalis .Seven patients presented "8" re-entry, and the gap of upper and lower loop located in CT in 4 cases, another 3 cases with upper loop and free-wall single-loop re-entry. RF of CT gap and/or the free-wall channel was effective in eliminating these AFLs in 13 patients.

结果 经 NMS标测证实13例患者折返均在右房内，激动在右房内的折返平均时间为230±20ms.6例房扑患者为单折返环，围绕右房中心障碍区折返，激动在心房的前壁穿过中心障碍区与界瘠之间的狭窄通道。7例患者证实为2个折返环，其中4例表现为上下折返环形成"8"字形折返，共同的传导通道在界瘠；另外3例表现为折返环1个在心房上部，1个在前游离壁。13例消融界瘠或前游离壁后房扑终止。

The length, width, axial gradient for the crowns,the heigh of gingival line,the width of anterior dentition and the ratio of crista marginalis of their teeth were measured and analysed in their photographs and dental casts after orthodontic treatment.

测量关于正畸治疗后上颌第一前磨牙和对侧尖牙的龈缘线高度和牙齿形态的6项指标：龈缘线高度、临床冠长度、宽度、单侧前牙列宽度、轴倾度和近远中边缘嵴比，进行两均数配对t检验，观察分析两组的差异。

Sertoli cells can provide a material basis and a favorable microenvironment for sperm. After X radiation, spermatogenic cells and mitochondrion dramatically swelling and lysis with a decrease of mitochondrial cristae, with the prolonging of time, the mitochondria damage get even worse, mitochondrial crista is disappeared.

Sertoli细胞在精子发生过程中可为精子发生提供物质基础和能力，为精子发生提供有利的微环境，对精子的生成有复杂的作用。X射线照射后即出现生精细胞和支持细胞线粒体明显肿胀，线粒体嵴减少，且随着时间延长，线粒体形态的损害进一步加重，线粒体数量减少，线粒体嵴消失。

There was BMP4 expression at E10 in epithelium of otic capsule. Later, BMP4 expressions were affluent in condensed mesenchyme, vestibular cartilage capsule and sense epithelium. 3. The expression pattern of Smad4 in vestibule is different from BMP4. It was not conspicuous until E15 that Smad4 expressed in macula and crista ampullaris and until E16 in periotic cartilage capsule.

BMP4从E10开始，在间充质浓聚前就有表达；间充质一开始浓聚，BMP4在其中就有较丰富的表达；早期主要表达在前庭囊及前庭囊周围的间充质，在胚胎发育的后期，其在软骨囊及前庭上皮里有广泛阳性表达。3。

Atrophied microvilli and broken mitochondrial crista were observed in TPN group,higher microvilli and less damaged mitochondrial crist a were seen in SCFA group.

对照组则出现明显线粒体肿胀，嵴短小紊乱和微绒毛萎缩。

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).
