急性心肌梗死(AMI)时患者病情危急,生命体症不稳定,随时都有生命危险,而在情况允许可行非体外循环下冠脉旁路移植术(OPCAB)可以避免体外循环对患者生理机能的影响,使患者术后较快恢复.我院2004-12～2005-10对5例AMI患者行OPCAB,效果满意,现将麻醉处理总结如下.

Objective To investigate the pathways of the lymphocytes homing in the hemolymph node,through the morphologic study of the high endothelial venules(HEVs) and lymphatic labyrinths in the hemolymph node.Methods We observed the structure of the rat hemolymph node by light microscopy,transmission electron microscopy and scanning electron microscopy.Results There were plenty of the HEVs in the hemolymph nodes.The endothelial cells were thick and process to the lumen.The organelles in the high endothelial cells were plentiful.The lymphocytes were found to adhere or penetrate the endothelial cells and the junction septum of the endothelial cells.In the paracortex of the hemolymph nodes,the tubular or pocket lymphatic labyrinths which were densely filled with small lymphocytes were found.Conclusion The hemolymph nodes are one of the important situations of the lymphocytes homing.
