保留冠状动脉的猪心螺旋形心室肌带的解剖

Objective Based on the Helical Ventricular Myocardial Band (HVMB) theory proposed by Torrent-Guasp,the ventricular myocardial hand extends from the root of the pulmonary artery to the root of the aorta with two helical coils.This new theory is considered as a revolutionary concept for further understanding the global, three-dimensional and functional architecture of the ven- tricular myocardium. No repot had described techniques for disecting HVMB while keepin～ the integrity of the coronmy artery sys- tern. We explored techniques for dissecting HVMB in swine.Methads 33 fresh swine hearts were randomly divided intoll groups, 3 bearts in each. 160% barium sulfate (type I)suspmmion was injected into the coronary artery system. The coronary arteries were li- gated. The strial tissue was removed following puuing the hearts in boiling water then cooling for several hours. The superficial coro- nary vessels and fat tissue around the atrio-ventricular taxi inter-ventricular sulcus we～'e preserved. Some branches of the left anterior descending artery, distal segment, of posterior descending branch, and middle and distal segment of obtuse marginal branches were mu- tilated appropriately. HVMB dissection was completed with fingers in accordnce with Torrent Guasp' s technique. Results A contin- ued bundle of muscle, originated at the root of pulmonary artery and ended at the root of aorta, was unwrapped along the major dire- tion of the cardiac muscle fiber in all of the 33 hearts with spating of the coronary artery. The swine hearts' ventricular myocandium was cumosed of two loops, with basal loop firm the root of the pulmonart artery to the anterior papillary muscle and apical from the beginning of the anterior papillary muscle to the root tithe aorta. Each loop consisted of two segments: the right segment-coincid- ing with the right ventricular free wall and the left segment-coinciding with the basal d the left ventricular free wall. Posterior papillary muscle, which belongs to the descendant segment, denmrcated the border between the descendent and the ascendant of the HVMB's apical loop. Conclusion Although controversies about the theory of the HVMB remain, we have dissected the HVMB in the swine hearts' ventricular myocardium successfully with sparing of the coronary artery systems. This dissection procedure provides technical information for the studies of associated diseases based on the theory of HVMB.

钾通道开放剂拮抗内皮素-1的缩血管作用

利用离体猪心冠状动脉环，研究了KATP开放剂吡那地尔（PIN）和克卡里木（CRO）对内皮素－1（ET－1）缩血管作用的影响。结果表明，PIN和CRO均使ET－1的量－效曲线右移，并降低最大反应。当ET－1（30nmol／L）达最大效应后，累加剂量的PIN和CRO产生剂量依赖性的抑制作用。结果提示，KATP开放剂对ET－1收缩冠状动脉的拮抗作用，可能是其抗心肌缺血的机制之一。
