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.접 수 일：2009. 3. 4. 채 택 일：2009. 5. 27. 교신저자：김윤하 E-mail：kimyh@chonnam.ac.kr
Results:<.b> 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.
