개심수술후 혈장 단백 및 보체 ($C_{3}$ , $C_{4}$ )의 변화상 추적
The changes of the plasma protein and the complements ($C_{3}$ , $C_{4}$ ) after open heart surgery
초록
The extracorporeal circulation has been much improved recently, but has yet much complex problems such as the protein denaturation and the activation of the complement system by the exposure of the blood to the foreign surface, which may result in such as the postperfusion syndrome. We studied the changes of the plasma protein fractions by the electrophoresis and the complement consumption [C3, C4] by the immunodiffusion method in the patients undergoing cardiac operation from Mar. 1, 1986 to Aug. 31, 1986. The results were summarized as follows: 1. y-globulin fraction was decreased [p<0.02 by paired t-test, N=25], but a,-globulin was increased [p<0.001 by paired t test, N=25] after operation. 2. C3,C4 were significantly reduced [p<0.001 by paired t-test, N=14] postoperatively and normalized from 24 hours after operation. 3. The consumption of C3,C4 had significant linear correlation [correlation coefficient r=0.97] and C, was more markedly reduced comparing with C3, which probably means the complement activation by classical pathway in our bubble oxygenator group.
