Results in normal mice, perforin was negative and connexin 43 was located in the intercalated disks of cardiac muscle.

结果：正常小鼠心肌中未见穿孔素阳性表达，连接蛋白43在心肌闰盘中呈阳性表达。

The cells in the HB were larger than the transitional cells, with abundant chromatin in the nuclei, more myofibers and myofibrils and branches. The intercalated disks were well developed.

房室束细胞比移行细胞大、核染色质多、肌丝和肌原纤维及其分支也多、闰盘发达完整。

Results In normal mice, connexin 43 and desmin are located in the intercalated disks of cardiac muscle, and the latter also revealed a positive immunoreactivity in the cross striations of sarcomeres.

结果连接蛋白43和结蛋白在正常小鼠心肌闰盘中定位分布，均匀存在，后者还在肌节横纹中显示阳性；
