摘　　要：The membrane-phospholipid (MPL)injury of myocardial cells may play an important role in the development of heart failure.In present study, peripheral lymphocytes were used as a study model in which the protective and reparative effects of Captopril and Cocnzyme 10 (Coo10)on mitochondrial MPL injury were observed. 42 hospitalized patients with dilated cardiomyopathy(DCM),on conventional anti-heart-failure therapy, were divided into three groups at random,and Captopil (Capton),Neuquinone 10 (CoQ10) and placebo were added respectively.The A4PL localization was proceeded by modified Demer's tricomplex flocculation.After mean 75'5 days observation,in Captopril and CoQ10 groups, heart function was improved,with circulatory A1 decreased,the degree of mitochondrial proliferation of lymphocytes decreased and the mitochondrial MPL injury repaired in certain degree.The percentages of the lymphocytes with less than 5 mitochondria per lymphocyte increased [(60.0± 9.4)vs (72.0± 6. 8)% for Captopril;(55.0±8.9) vs (73.1 ± 9. 8)% for CoQ10, P<0. 001];the percentages of mitochondria with intact MPL localization increased [(59. 1 ± 8. 1 ) vs (72. 0± 9. 4)% for Captopril;(56.6±9.3) vs (73.8±9. 4)% for CoQ10 P< 0.001].But no significant changes were found in either the proliferation or MPL injury in the con trols. In conclusion,Captopril and CoQ10 have a beneficial effects on the protection and reparation of mitochondrial injury in patients with DCM.The membrane-phospholipid (MPL)injury of myocardial cells may play an important role in the development of heart failure.In present study, peripheral lymphocytes were used as a study model in which the protective and reparative effects of Captopril and Cocnzyme 10 (Coo10)on mitochondrial MPL injury were observed. 42 hospitalized patients with dilated cardiomyopathy(DCM),on conventional anti-heart-failure therapy, were divided into three groups at random,and Captopil (Capton),Neuquinone 10 (CoQ10) and placebo were added respectively.The A4PL localization was proceeded by modified Demer's tricomplex flocculation.After mean 75'5 days observation,in Captopril and CoQ10 groups, heart function was improved,with circulatory A1 decreased,the degree of mitochondrial proliferation of lymphocytes decreased and the mitochondrial MPL injury repaired in certain degree.The percentages of the lymphocytes with less than 5 mitochondria per lymphocyte increased [(60.0± 9.4)vs (72.0± 6. 8)% for Captopril;(55.0±8.9) vs (73.1 ± 9. 8)% for CoQ10, P<0. 001];the percentages of mitochondria with intact MPL localization increased [(59. 1 ± 8. 1 ) vs (72. 0± 9. 4)% for Captopril;(56.6±9.3) vs (73.8±9. 4)% for CoQ10 P< 0.001].But no significant changes were found in either the proliferation or MPL injury in the con trols.
