妊娠晚期阴道分泌物和胎盘的细菌、支原体及病理研究

Studies on Bacteria Mycoplasma and Pathoiogical Changes of Vaginal Secr- etion and Placenta in the Third Trimester of Pregnancy.

125例妊娠晚期阴道分泌物和胎盘的细菌、支原体及病理的研究。其中、胎膜早破组的阴道分泌物需氧菌和厌氧菌的阳性率明显高于对照组。且胎膜早破组中厌氧菌感染阳性率、比需氧菌感染阳性率明显增高;胎膜早破组中胎盘组织学检查有不同炎症程度的绒毛膜炎、羊膜炎比对照组明显增高;

Bacteria, mycoplasma and pathological changes of vaginal secretion and placenta in 125 cases of the third trimester pregnancies were studied from December, 1990 to November, 1991 in our hospital. In the series 57 were of premature rupture of membranes(PRM), and 68 of non-premature rupture of membranes(NPRM) which served as control. The results showed that: (1) The positive rate of aerobic and anaerobic bacteria of vaginal secretion in the PRM group were obviously higher than that in NPRM group(P<0.05, P<0.001), the infective rate was 64.91％ and 29.82％ respectively, (2) The positive rate of anaerobic bacteria in placentas of PRM group was notably higher than that of NPRM group(P<0.001), (3) Pathologically, the inflammation degree of chorioamnionitis in the PRM group have increased markedly in contrast to that in NPRM group(P<0.05), (4) There was no significant difference of mycoplasma infection between the two groups(P>0.05).
