Visualization of the arteries, veins, and nerves of the orbit by sector computed tomography

Altering the scintillation crystal configuration of a fixed-detector CT scanner increased the spatial resolution from 6.25 to 10 line pairs per centimeter. Sector scans of th orbit with this modified scanner showed the ophthalmic artery and superior ophthalmic vein and their branches and the intraorbital branches of the third, fifth, and sixth nerves, apparently seen with CT for the first time.     

An ISDN for the UK

With the advent of new digital technology into public telecommunications networks and given the fact that voice and data are carried in essentially the same way across a digital network, it is realized that the integration of voice and data services is possible and cost effective, and may bring additional benefits. The paper sets out some of the current developments in this area, with an emphasis on British Telecom's pilot Integrated Services Digital Network.     

Lipid-protein interactions with native and modified myelin basic protein

The basic protein of central nervous system myelin has been shown to form complexes with acidic lipids in vitro. We measured the interaction of myelin basic protein with several charged and neutral lipids in a biphasic chloroform/methanol/water system and investigated the effect of decreasing the electrical charge of the basic amino groups of the myelin basic protein by acetylation. The modified myelin basic protein, which has an average of eight acetyl residues incorporated, was characterised by gel electrophoresis and circular dichroism. Complexes formed between the acetylated myelin basic protein and acidic lipids exhibited a reduction in the amount of lipids bound, a value that could be correlated with the number of modified amino groups. The significance of these experiments with reference to protein-lipid interaction in the myelin membrane is discussed.     

Role conflict and ambiguity scales: Reality or artifacts?

Discusses 2 arguments against the role conflict and ambiguity scales developed by J. R. Rizzo et al (see record 1971-01407-001). The arguments focus on the positive and negative wording of the scale items and the self- and other-attributions found in the wording of the scale items. These arguments, if substantiated, would suggest modification of the Rizzo et al scales. The present study, with 272 adults, provided evidence that such arguments may not be able to be substantiated and that modification of the scales based on these arguments may not be necessary.

Initial experience of clinical pharmacology and clinical pharmacy interactions in a clinical pharmacokinetics consultation service

International statistics indicate that there is a close correlation between the consumption of saturated fats (dairy fats and meat fats) and the mortality from coronary heart disease (CHD), and this conception has been confirmed by many epidemiological studies. Such studies alone, however, cannot prove the existence of a cause-and-effect relationship between these two variables; dietary intervention trials are needed. The Finnish Mental Hospital Study was such a trial, conducted in two hospitals near Helsinki in 1959--1971. Practically total replacement of dairy fats by vegetable oils in the diets of these hospitals was followed by a substantial reduction in the mortality of men from CHD. Total mortality also appeared to be reduced. As to the causes of death other than CHD, none was significantly influenced by dietary change. This was also true for malignant neoplasms. To alleviate the burden of CHD on public health, many investigators have recommended important changes in the quantity and quality of dietary fats.
