[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)

[Ontogeny of behavioral patterns in relation to the concurrent development of central nervous system function, focusing on REM sleep, NREM sleep and waking states in the human fetus].
Behavior is considered a one to one match between the manifestation of a particular individual motor activity (movement) and its correlated brain function. Each motor activity can be seen to run on its own developmental course with advance in gestation, while various movements also develop in concurrence with one another during intrauterine life, gradually integrating into complex and accommodated movements. I emphasized the present study, under real-time ultrasound observation, for investigating whether or not three states: REM (rapid eye movement) sleep, NREM (non-rapid eye movement) sleep and the waking state actually exist in utero, and if so, when the development of these states begins. 1. ⋯ To evaluate whether the waking state is present, 10 fetuses at 36 weeks or more of gestation were examined for a concurrence between miosis/mydriasis and the REM/NREM periods. Using pupil diameter as a parameter, miosis and mydriasis were distinguished from each other, statistically, by means of "least median of squares regression". Accordingly, the NREM period was occupied only by miosis (41.0% of total observation period), while the REM period was divided into two conditions: 52.6% with miosis and 6.4% with mydriasis.(ABSTRACT TRUNCATED AT 400 WORDS)
