intercalated disk

Cx43 positive granules distributed irregularly in cell side surface and cytoplasm as well as intercalated disk in adult atrium .

2成人Cx43表达在心房肌非均质分布于细胞侧面连接处和端闰盘处；

Conclusion The expression of Cx43 is transferred from cytoplasm and surface of the cardiocyte to intercalated disk .

结论随着年龄的增长Cx43从细胞侧表面向端-端闰盘处转移。

Conclusion : The Cx43 rearrangements were confined to the intercalated disk following the heart development of mice , with gradually decreased density .

结论：小鼠心肌细胞Cx43分布随心脏发育逐渐向闰盘处重排，其密度逐渐下降。

In ventricular bands Purkinje cells could be seen in groups under TEM , among Purkinje cells typical intercalated disk structure was formed in some parts .

电镜下可见Purkinje细胞群，细胞之间存在着特化连接，有些部位形成典型的闰盘结构。

At the level of the Z lines between adjacent cardiac muscle cells , the intercalated disk composed of3 main junctional specializations complexes .

在Z线处，可见心肌细胞之间含有3种连接方式的特有连接结构&润盘。

Conclusion The present paper demonstrated that the N-cadherin expression exists progressively with ages and the changing pattern of N-cadherin is closely related with development of the intercalated disk in rat myocardium .

结论在大鼠心肌发育过程中，Ncadherin的表达存在增龄变化；以Ncadherin介导的细胞黏合连接与闰盘的发育有着密切的联系；

Results Compared with adult group , aging group : ( 1 ) The nuclei were indented , myofibril were arranged irregularly , intercalated disk were separated , mitochondria and sarcoplasmic reticulum were swelled , lipofuscin and residual body were increased .

结果与成年组比较，老龄组大鼠心肌改变：（1）核有切痕、肌原纤维不规整、闰盘离解、线粒体和肌浆网肿胀、脂褐素和残余体增多。

Treated with Shenmai injection , it could alleviate cardiomyocyte degeneration in infarcted region ; myofibril and intercalated disk were more regularly than the model group . Mitochondria swelled , crista lightly ruptured even vacuolization , but it was more alleviated than model group in corresponding time .

参麦注射液治疗后，梗死区心肌细胞变性程度减轻，肌原纤维排列较模型组规则，闰盘较整齐，线粒体虽仍有肿胀、轻度峭断裂甚至空泡化，但较相应时间点模型组明显减轻。
