obtain their surface in square centimeters. This simple method provides a means by objective measurements to make evident ehanges in the surfaee of wounds that are not apparent to the naked eye. Figure 1 shows. the observations recorded with this method :in a man of 42 years of age with hemiplegia and a decubital ulcer over the right buttock. The clini cians who had observed this wound daily had not noticed any remarkable change; however, it is quite obvious that the wound grew larger each time the treatment was changed, and that the use of an anti bi6tic was followed by a particularly striking enlarge ment of the lesion. In this instance the procedure of projection and gravimetric planimetry was repeated by different operators and a variation of ±5% was found (indicated by a cross-hatched area on Fig. 1). Figure 2 shows the same type of observation in a woman with hemiplegia and a dcenbital ulcer. This patient died from septicemia, and the decubital ulcer worsened with the general condition -of the patient. A method of gravimetric planimetry by standard photographs offers a means to study the course of surface wounds more accurately than by clinical ob servation or by the pictorial record alone. Refenn_

IN 1953, ASERINSKY AND KLEITMAN DISCOVERED HUMAN RAPID EYE MOVEMENT (REM) SLEEP AND DOCUMENTED THAT DREAM REPORTS WERE OBTAINED MOST FREQUENTLY WHEN SUBJECTS WERE AWAKENED FROM REM SLEEP.1 Thereafter, many scientists conducted studies on dream and REM sleep and found a robust association between electrophysiologic phenomena and subjective experiences during REM sleep.2–7 This well-documented as...
متن کاملBaroreflex buffering of sympathetic activation during sleep: evidence from autonomic assessment of sleep macroarchitecture and microarchitecture.
We examined the effects of sleep microstructure, ie, the cyclic alternating pattern (CAP), on heart rate (HR)- and blood pressure (BP)-regulating mechanisms and on baroreflex control of HR in healthy humans and tested the hypothesis that sympathetic activation occurring in CAP epochs during non-rapid eye movement (non-REM) sleep periods is buffered by the arterial baroreflex. Ten healthy males ...
متن کاملDisfacilitation and active inhibition in the neocortex during the natural sleep-wake cycle: an intracellular study.
Earlier extracellular recordings during natural sleep have shown that, during slow-wave sleep (SWS), neocortical neurons display long-lasting periods of silence, whereas they are tonically active and discharge at higher rates during waking and sleep with rapid eye movements (REMs). We analyzed the nature of long-lasting periods of neuronal silence in SWS and the changes in firing rates related ...
