OBJECTIVE The purpose of this study was to determine the efficacy of real-time sonography for the detection and estimation of the volume of pneumothorax using receiver operating characteristic (ROC) analysis in 27 patients evaluated by five radiologists using previously described sonographic findings. MATERIALS AND METHODS Bilateral chest sonograms were(More)
Modulation of CA1 field potential amplitudes by normal and stress concentrations of corticosterone (CT) was observed in hippocampal slice preparations from adrenalectomized rats. Slices exposed to CT levels characteristic of a morning (4 nM) or evening (7 nM) resting state showed increased population spike amplitudes in the CA1 pyramidal cell field within(More)
The objective of this work is to evaluate the significance of finding reversal of flow in the inferior epigastric artery during noninvasive assessment of the lower extremity circulation using Doppler ultrasonography. This phenomenon is easy to demonstrate when present and predicts aortic or iliac artery stenosis or occlusion at subsequent arteriography. We(More)
Three cases of fatality related to the use of low-osmolality contrast material (LOCM) are presented. LOCM definitely reduces unpleasant side effects and serious reactions, but data are currently insufficient to determine whether the death rate is any different from that associated with high-osmolality contrast agents. If the present trend toward universal(More)
The present study was designated to determine the origin of commissural axons in the hippocampus. One hippocampus of 94 rats was pressure injected with 40% horseradish peroxidase (Sigma VI), or with 2-4% wheat germ agglutinin HRP (E-Y Labs). Injections (0.001 to 0.1 microliter) were made through glass micropipettes with fitted plungers. Pipettes were(More)
