The systolic time intervals and hemodynamics were measured in 10 cases of acute anemia and 28 cases of chronic anemia. The measurment was done by non invasive technique, i.e., simultaneous recording of ECG, PCG and carotid and femoral pulse tracing with paper speed 100mm/sec. Compared with healthy persons chronic anemia showed significant reduction of the systolic time intervals except QS1, but the systolic time intervals were unaltered when they were corrected by pulse rate, diastolic pressure and stroke volume. Acute anemia showed decreased of the systolic time intervals except QS1 also the decrease of isovolumic contraction time(ICT) and QS2 when corrected as above. The preejection period(PEP)/left ventricular ejection time(LVET) ratio were not altered. ICT, PEP and PEP/LVET ratio decreased in proportion to the levels of hemoglobin. The heart rate, stroke volume and cardiac output showed significant increase in chronic anemia but mild incease in acute one. The decrease of diastolic pressures and peripheral resistances were more pronounced in chronic anemia than in acute one.

OBJECTIVE: To evaluate the degree of streptococcal colonization in Korean pregnant women. METHODS: The study comprised of 153 singleton pregnant women who visited Severance Hospital for delivery, and their neonates. Specimens for GBS culture were collected by a sterile cotton swab from lower vagina and cervix of pregnant women, and from ear canal and throat of neonates. They were first cultured for 48 hours in Todd-Hewitt broth and then subcultured onto Tryptose blood agar plates(Difco). Group B streptococci were confirmed by the presence of beta-hemolysis and a positive reaction with Phadebact group B Streptococci reagent(Karo Biodiagnostics AB, Huddinge, Sweden). RESULTS: The prevalence of positive cultures in pregnant women and neonates were 2.61%(4/153) and 0%(0/4), respectively. In the study population there was a case of suspicious group B streptococcual sepsis in an infant whose mother was colonized. CONCLUSIONS: In our study the GBS colonization rate in Korean pregnant women was significantly lower than that of other countries. The reason for this difference may be associated with a racial differences, or social factors such as socio-economic status or a life style.
