목적: 만삭 전 조기양막파열 임부에게 항생제를 투여한 후 정맥혈장 내 지질과산화도와 단백산화도를 비교분석하여 이들이 어떤 영향을 미치는 가에 대하여 규명하고자 한다. 연구 방법: 임신 25주 이상 32주 미만의 만삭 전 조기양막파열 임부 36명 중 1군 18명은 amoxacillin계와 erythromycin계 항생제를 7일간 병합 투여하고, 2군 18명은 3세대 cephalosporin계 (cefodizime, cefditoren)와 erythromycin계 항생제를 7일간 병합 투여하였다. 각 군에서 투여 전, 3일째, 7일째 팔오금 중간정맥혈을 채취하고 원심분리 후 혈장을 얻었다. Thiobarbituric acid 반응을 이용하여 지질과산화물 농도를 측정하였고, 2,4-dinitrophenylhydrazine 방법을 이용하여 단백질의 carbonyl기 함량을 측정하였다. 대조군으로 임신 25주 이상 32주 미만 정상임부 18명의 정맥혈장을 얻어 시험관 내 방법으로 지질과산화물 농도와 단백질의 carbonyl기 함량을 측정하였다. Interleukin (IL)-6은 enzyme-linked immunosorbent assay kit를 이용하여 측정하였다. 결과: 1. 만삭 전 조기양막파열 임부군 (18명)의 정맥혈장 내 지질과산화물 농도와 단백질의 carbonyl기 함량은 4.77±0.36, 7.11±0.41 nmol/mg protein으로, 정상임부군 (18명) 3.55±0.22, 5.69±0.30 nmol/mg protein보다 모두 유의하게 높았다 (P<0.01). 2. 만삭 전 조기양막파열 임부군 (18명)의 정맥혈장에서 시험관 내 방법으로 amoxacillin계, 3세대 cephalosporin계 및 erythromycin계 항생제를 처치한 전과 후에 측정한 지질과산화물 농도와 단백질의 carbonyl기 함량의 차이는 의의가 없었다. 3. 1군의 투여 전, 투여 3일째, 7일째 정맥혈장 내 지질과산화물 농도는 4.51±0.41, 4.33±0.28, 4.55±0.35 nmol/mg protein이며, 2군의 투여 전, 투여 3일째, 7일째 정맥혈장 내 지질과산화물 농도는 4.89±0.22, 4.62±0.21, 4.50±0.26 nmol/mg protein으로 유의한 차이는 없었다. 4. 1군의 투여 전, 투여 3일째, 7일째 정맥혈장 내 단백질의 carbonyl기 함량은 7.21±0.38, 7.53±0.41, 7.70±0.54 nmol/mg protein으로 유의한 차이는 없었다. 그러나 2군의 투여 전, 투여 3일째, 7일째 정맥혈장 내 단백질의 carbonyl기 함량은 7.04±0.51, 6.04±0.44, 5.53±0.37 nmol/mg protein으로 투여 전보다 투여 7일째가 유의하게 감소하였다 (P<0.05). 5. 1군의 투여 전과 7일째 정맥혈장 내 IL-6 농도는 6.82±0.38, 8.21±0.54 pg/mL으로 유의한 차이는 없었다. 2군의 투여 전과 7일째 정맥혈장 내 IL-6농도는 7.50±0.35, 3.13±0.37 pg/mL으로 유의하게 감소하였다 (P<0.05). 결론: 만삭 전 조기양막파열 시 정맥혈장에서 지질과산화와 단백질의 산화적 변화가 증가되어 있었으며, 3세대 cephalosporin계와 erythromycin계 병합치료에 의해 단백질의 산화도와 IL-6 생성이 감소되는 경향을 보였다. 이는 3세대 cephalosporin계와 erythromycin계 병합요법이 염증성 반응으로 발생되는 활성 산소를 억제시키는 효과를 나타낸 것으로 사료된다.

Abstract

Objective: To investigate and compare the amount of the lipid peroxidation and the protein carbonyls formation in maternal venous plasma of preterm premature rupture of membranes (PPROM) during antibiotics administration. Methods: PPROM were selected between 25 and 32 weeks of gestation. Eighteen patients (group 1) were treated with amoxicillin and erythromycin for 7 day period, 18 patients (group 2) were treated with 3rd generation cephalosporin (cefodizime, cefditoren) and erythromycin for the same period. Maternal blood were obtained from the two groups before and after the antibiotics administration, day 3 and day 7. Lipid peroxidation levels and protein carbonyl contents were measured by thiobarbituric acid reaction and 2,4-dinitrophenyl hydrazine method. Other 18 women with normal pregnancy between 25 and 32 weeks of gestation of venous blood were checked same things in vitro. Interleukin (IL) -6 was measured by enzyme-linked immunosorbent assay. Results: 1. The lipid peroxidation levels and protein carbonyls formation in the maternal venous plasma of PPROM was significantly higher than that of normal pregnancy (lipid peroxidation levels; 4.77±0.36 vs 7.11±0.41 nmol/mg protein, P<0.01, protein carbonyls formation; 3.55±0.22 vs 5.69±0.30 nmol/mg protein, P<0.01). 2. There were no significant differences in the lipid peroxidation levels and protein carbonyls formation of the maternal venous plasma with PPROM mixed and incubated by amoxicillin, cefodizime, cefditoren, and erythromycin (in vitro). 3. There were no significant differences in the lipid peroxidation levels and protein carbonyls formation of the venous plasma of group 1 between before and after antibiotics administration, day 3 and day 7. 4. There were no significant differences in the lipid peroxide levels of the venous plasma of group 2 between before and after antibiotics administration, day 3 and day 7. 5. The protein carbonyls formation in the venous plasma of group 2 was significantly decreased at day 3 and day 7 after antibiotics administration than that of before (6.04±0.44 and 5.53±0.37 vs. 7.04±0.51 nmol/mg protein, P<0.05). 6. The levels of IL-6 in the venous plasma of group 2 was significantly decreased at day 7 after antibiotics administration than that of before (7.50±0.35 vs. 3.13±0.37 pg/mL, P<0.05). Conclusion: In the maternal venous plasma of PPROM, the lipid peroxidation levels and protein carbonyls formation were increased. The formation of protein carbonyls and IL-6 in the maternal blood of PPROM was decreased by combined treatment of 3rd generation cephalosporin and erythromycin. The results suggest that reactive oxygen species formation by inflammatory reaction is suppressed by the 3rd generation cephalosporins and erythromycin combined treatment.
