Treating adults with eating disorders by using an inpatient approach.

Although eating disorders like anorexia nervosa and bulimia have received wide attention in the media, specific treatments for specific populations have received less notice. Treating adult patients in the hospital can be a successful approach to dealing with these complex and multifaceted conditions, as the program outlined here illustrates.

Effect of fibronectin on adherence of neutrophils from newborn infants.

Neutrophils (polymorphonuclear leukocytes [PMNs]) from infants and adults increased in adherence over a 20-min incubation as measured in a morphological assay. At each time point, PMNs from healthy infants had significantly diminished adherence when compared with those of adults; PMNs from sick newborn infants showed intermediate adherence values. Moreover, PMNs from healthy infants had significantly diminished membrane fluorescence for fibronectin when compared with those of adults.

The growth of technology and corporate profit-making in the clinical laboratories.

This article examines private industry's involvement in the area of clinical laboratory testing, as an example of the relationship between the increased cost of medical care and increased involvement of private industry in the health care sector. After tracing the history of corporate and technological development in the clinical laboratory field, and particularly in the area of blood chemistry analysis, the article suggests some implications for public policy of the current state of affairs.

The deafferentation syndrome in monkeys: dysesthesias of spinal origin.

Chronic thoracic spinal lesions were surgically placed in 35 monkeys of 6 different species. In a very large percent of the cases, a bizarre behavioral pattern was released, which persisted for many months of observation. This syndrome was one in which the monkey severely attacked an hypoalgesic area of the body, namely, the leg.

Aspirin absorption from a feeding jejunostomy.

In a 67-year-old man who had a feeding jejunostomy because of dysphagia paralytica, the absorption of aspirin was measured in terms of serum salicylate concentration. A 975-mg dose of aspirin was given as a slurry in water directly into the feeding tube. Peak serum levels of salicylate were well correlated with those in previous studies of aspirin absorption by the oral route in a geriatric population.

Materials for luminescent greenhouse solar collectors.

Luminescent greenhouse solar collectors are potentially useful for concentrating sunlight onto photovoltaic power cells. Measurements of the performance of small-scale collectors made of two commercially available materials (Owens-Illinois ED2 neodymium-doped laser glass and rhodamine 6G-doped plastic) are presented. The results are encouraging, but they indicate a need for further spectral sensitization and for reduced matrix loss coefficient.

Freezing Injury in Onion Bulb Cells: II. Post-thawing Injury or Recovery.

Onion (Allium cepa L.) bulbs were subjected for 12 days to either a moderate freeze (-4 C) or a severe freeze (-11 C). They were then thawed slowly over ice.

Freezing injury in onion bulb cells: I. Evaluation of the conductivity method and analysis of ion and sugar efflux from injured cells.

Onion (Allium cepa L.) bulbs were frozen to -4 and -11 C and kept frozen for up to 12 days. After slow thawing, a 2.

Mechanical vibrations: mapping their phase with hologram interferometry.

Generally, both the phase and amplitude of vibration of an object's surface vary from point to point. This paper details two methods for extracting vibrational phase information from the higher order fringes of holographic interferograms recorded by phase modulating either the object or reference illumination. Both methods require the superposition of only a few transparencies of interferograms in order to generate useful vibration-phase contour maps.

Methodology for intraventricular and subarachnoid continuous recording of intracranial pressure in clinical practice.

The methodology for continuous monitoring intracranial pressure (ICP) being presently employed in the Neurosurgery Service of the University of Pennsylvania is presented. The methods are intraventricular recording of ICP (IVP) and subarachnoid recording of ICP (SaP). The indications for employing either method are briefly presented.

The biochemical basis of anesthetic toxicity.

The inhalational anesthetics reversibly inhibit mitochondrial electron transport from NADH-linded substrates at the level of the enzyme NADH-dehydrogenase. The effect of this inhibition on ATP production is probably not the basis of the anesthetic state, as the level of high-energy phosphate in the brain does not decrease during anesthesia. Anesthetics, therefore, interfere with brain energy untilization, in addition to brain energy production.

The effects of halothane and enflurane on rat brain synaptosomal sodium-potassium-activated adenosine triphosphatase.

Synaptosomes, or nerve-ending particles, were isolated from the cerebral cortices of young rats by homogenization, differential centrifugation, and density-gradient centrifugation. The sodium-potassium-activated adenosine triphosphatase enzyme system [(Na+ plus K+)-ATPase] of these particles is believed to represent in vitro the sodium-potassium pump of the nerve terminal. Suspensions of synpatosomes were equilibrated with air containing various concentrations of halothane and enflurane, as determined by gas chromatography.
