The kinetic changes of serum myoglobin ( Mb ) ,lactatc dehydrogenase(LDH1) isoenzyme and aspartate aminotransferase (AST) were observed in 70 cases of epidemic hemorrhagic fever (EHF) . It was found that myoglobin was significantly elevated, 117.7±100.3 ng/ml, in early stage as compared with the concentration, 36.4± 17.22 ng/ml, in 84 normal subjects. The highest value was in hypotensive stage, and the value gradually 'returned to normal in polyuric and convalescent phases. The elevation range was correlative...

The kinetic changes of serum myoglobin ( Mb ) ,lactatc dehydrogenase(LDH1) isoenzyme and aspartate aminotransferase (AST) were observed in 70 cases of epidemic hemorrhagic fever (EHF) . It was found that myoglobin was significantly elevated, 117.7±100.3 ng/ml, in early stage as compared with the concentration, 36.4± 17.22 ng/ml, in 84 normal subjects. The highest value was in hypotensive stage, and the value gradually 'returned to normal in polyuric and convalescent phases. The elevation range was correlative with the severity of the disease, and also reflected the degree of myocardial damage. Owing to the early elevation of serum Mb, LDH1 and AST concentrations,it is considered that the determination of Mb, LDH1 and AST may be used as an index of early diagnosis for the EHF with myocardial damage.

测定了70例流行性出血热患者血清中Mb、LDH同功酶、LDH_1/LDH_2比值及AST与心肌有关的生化成分变化,用以推断患者可能发生的心肌损害。该病患者于发热期即见其血清中Mb升高,低血压期达高峰,少尿期开始下降;LDH_1/LDH_2比值及AST的上升基本同上规律。提示,此Mb系来自心肌受损。且其上升程度与病情轻重相关。故认为该检验有助于观察该病患者心肌损害的辅助诊断。

The regional ejection fraction (EF2-EF6) and radial shortening (RS1-RS5) ofthe left ventricle might reflet the regional systolic functicn and regional wall motion. 30 cases withmyocardial infarction (ML), 20 cases with essential hypertension (EH) and 15 normal subjectswere observed using gated cardiac blood pool imaging method (MGBP). The results showed thatthe alteration of regional EF and RS in MI group was in accordance with the location of MI (40/46.85 %). Comparing with nomal controls, there was significant difference between (EF1-EF5)and (RS1-RS5) (P<0.05-0.001) in MI group. ALL EF, RS in EH group except EF4 and RS4had no significant difference in comparison with those in normal controls (P<0. 05). There were positive relationships between (EF1-EF1) and (RS1-RS5) (P<0.05-0.001) in all of these patients. These results indicated that examination of regional EF and RS on the left ventricle usingMGBP was available for the diagnosis of the location of myocardial damage and observation of the change of cardiovascular diseases.

本研究运用门控平衡法心血池显像(MGBP)观察了心肌梗塞组(MI)30例,原发性高血压病组(EH)20例及对照组(N)15例三组的左室局部射血分数(EF_1—EF_5)及局部轴缩短率(RS_1—RS_5)的变化,发现 MI 组的局部 EF 及 RS的变化与梗塞部位相符(40/46、85%),与 N 组比较各部位EF与RS均有显著性差异(P<0.05—0.001).EH组与N组比较除EF_4、RS_4的差异有显著性意义(P<0.05)以外,其余EF、RS两组的差异无显著性意义(P>0.05),提示左室局部EF及RS改变对于判断MI及EH的病变部位和病情变化有确定的应用价值.三组各部位EF与RS均呈正相关关系(P<0.05—0.001).

Purpose: To test the feasibility of isonitrile tomography indemonstrating the size of myocardial damage and the approach for detecting viable myocardium with 99mTc-MIBI SPECT by nitroglycerin (NTG) administration before the tracer injection. Materiais and Methods: 7 mongrel dogs with acute myocardial infarctions by ligating coronary arteries underwent resting SPECT imaging and post-NTG imaging on the first and seventh day. The sizes of tracer uptake defect were quantified from circumferential profiles in 6 short-axis slices. Results: The final scintigraphic perfusion defect sizes correlated well with the pathologic sizes(r=0. 86 and r=0. 87by resting and post-NTG resting imaging, respectively). From initial to final imaging, the mean defect areas were significantly decreased(P<0. 05 ). After NTG, the mean defect sizes were significantly decreased(P<0. 01) and the mean counts of the defect region were significantly increased(P<0.05 ) in both the initial and final imagings. Conclusion: 99mTc-MIBI SPECT is auseful method to demonstrate the size of myocardial damage and the administration of NTG before resting MIBI injection may improve the detection of residual viability in hypoperfused regions.

目的:评价99m锝一甲氧基异丁基异腈(99mTc-MIBI)SPECT显像对心肌梗塞范围的估测及硝酸甘油介入后对存活心肌检测的价值。材料和方法:7条杂种犬通过结扎冠状动脉造成心肌梗塞模型,分别在实验第一天及实验第七天行99mTc-MIBISPECT静息显像及硝酸甘油介入99mTc-MIBI心肌显像。用圆周剖面法定量分析短轴6个断面心肌缺损面积大小。结果:末次显像缺损面积与病理梗塞面积有良好相关性(r=0.86和r=0.87分别为硝酸甘油介入前后心肌缺损面积与病理梗塞面积的相关系数),末次显像与首次显像相比缺损面积明显缩小(P<0.05),硝酸甘油介入后心肌显像的平均缺损面积在首次和末次显像均明显减小(P<0.01),且缺损区的平均计数在硝酸甘油介入后均明显增高(P<0.05)。结论:99mTc-MIBI心肌断层显像是了解急性心肌梗塞范围的较好手段及硝酸甘油介入99mTc-MIBISPECT显像可以提高检测低灌注区残存的存活心肌。
