[Effect of maternal postural change on maternal hemodynamics in late pregnancy--supine hypertension].
The purpose of this investigation was to ascertain the effect of postural change in late pregnant women from the left lateral recumbent position to the supine position on their blood circulation. Patients in whom the blood pressure at the right upper limb in the supine position increased by at least 20mmHg or more (diastolic and/or systolic pressure) were classified as the supine hypertensive group. Patients in whom the blood pressure of the right upper limb decreased by at least 20mmHg or more were classified as the supine hypotensive group. ⋯ CVP (central venous pressure) and PCWP (pulmonary capillary wedge pressure) shows different pattern of change in the supine hypertensive group and the no blood pressure change group. In the former group, CVP was decreased by 45 +/- 16% and PCWP was increased by 21 +/- 9% in the supine position compared with in the left lateral recumbent position. However, in the latter group, CVP decreased by 87 +/- 69% and PCWP decreased by 53 +/- 46% as the result of the same postural change.(ABSTRACT TRUNCATED AT 250 WORDS)

[Developmental sequence of fetal behavior and the functional development of the fetal central nervous system].
The development of central nervous system (CNS) is the latest among the various fetal organs and is on the way to mature even at birth. Because behavior is the phenotype of the CNS function, the behavioral pattern significantly changes with the developmental stage of CNS throughout the whole fetal period. The purpose of this study is to clarify the developmental sequence of fetal behavior and to discuss the functional development of the fetal CNS. ⋯ The other movements showed the respective patterns of the changes in the incidence. Secondly, animal experiments were performed to obtain the basic data on fetal behavior which could not be given by the ultrasonographic observation of human fetuses. Fetal goats were incubated under the physiological condition in artificial amniotic fluid by using extracorporeal membrane oxygenation (ECMO) system.(ABSTRACT TRUNCATED AT 250 WORDS)
