The clinico-pathological studies on the placentitis were based on 32 cases of the premature ruprure of membranes which were selected on dept. of obstetrical service, St, Mary`s Hospital, Catholic Medical College, from Aug. to November 1968. 1. The prevalence of neutroptilic infiltration, especially in the decidua of the membranes, in placentas of women who were delivered on our service, is described. 2. Of the placentas examined by the 4 section method, 75 per cent had neutrophilic infiltration in the cases of premature rupture of membranes. 3. Moderate or severe placentitis (GradeII,III) could be correlated with premature rupture of mombranes. 4. No significant differences between normal and infected placental were noted in the matermal ages, parities, and dutation of labor. 5. The distal and proximal portion of the umbilical cord were found to be useful areas for determining whether or not severe placentitis is present, in as much as the presence of a definite neutrophilic infiltration in microscopic sections from both of these cord areas almost invaria- bly meant the presence of a severe placentitis. 6. Maternal blood leukocytes were likely seemed to be proportionate to degree of placentitis. 7. Of the amniotic fluid cultivated, 53.1 per cent had microorganisms in the placentitis due to premature rupture of membranes. Staphyloclccus and Escherichia coli were more prevalent pathogens in the premature rupture of membranes. 8. Furadantion and kantrex were useful antibiotics in the management of the placentitis.
