Using pulsed Doppler ultrasound velocimetry, we set out to examine (a) the significance of velocimetry as a monitor of fetal management (including fetal therapy), and (b) the correlation between the occurrence of abnormal blood flow values and perinatal morbidity. We compared the incidence of abnormal values between a control group of normal pregnant women(More)
We have developed a real-time terahertz time-domain polarization analyzer by using 80-MHz repetition-rate femtosecond laser pulses. Our technique is based on the spinning electro-optic sensor method, which we recently proposed and demonstrated by using a regenerative amplifier laser system; here we improve the detection scheme in order to be able to use it(More)
A case of a patient with premature ovarian failure (POF) is discussed. Ovulation failed to occur for 5 years by gonadotropin-releasing hormone agonist (GnRHa) and human menopausal gonadotropin (hMG) treatment following estrogen-progesterone replacement therapy. After laparoscopic ovarian biopsy, ovulation was successfully induced by hMG, although(More)
The combined antibiotics, sulbactam/cefoperazone (SBT/CPZ), was administrated intravenously to 10 patients with various kinds of gynecological infectious diseases and the efficiency of the drug was investigated clinically or bacteriologically. The results obtained were as follows. The clinical and bacteriological efficiency rate of SBT/CPZ on gynecological(More)
The left ventricular systolic time intervals (STI) and impedance cardiogram were studied in 295 newborn infants. The wave pattern of the carotid was mainly anacrotic, similar to the wave pattern of hypertensive adult patients. In the neonatal period Q-I and Q-II intervals were gradually shortened and the prolongation of the preejection period (PEP),(More)
