摘要:

No more arbitrary than the conventions long accepted in connection with mapmaking, color display of nuclear images offers many advantages: separating activity levels by assignment of different colors adds spatial resolution to scans; simultaneous use of different tracers can provide composite views of functional and structural interrelationships. Nor need color coding be complex; a system of only four colors is sufficient.

摘要:

Hypertensive subjects respond to given pressor stimuli with greater pressure rises than the normotensive. Does this exaggerated reactivity reflect a lower threshold of excitability or a difference in the force-generating contractile response of the vascular smooth muscle? Extensive animal experiments have not yet provided definitive answers but an intrinsic change in excitability is strongly supported.

摘要:

The view that the widespread systemic derangements seen in chronic renal failure result from retention of“toxins”is probably oversimplified. Rather, the uremic syndrome appears to reflect adaptations that, at a physiologic“price,”enable surviving nephrons to step up excretion and sustain kidney function. Understood this way, the syndrome may become subject to manipulations that can compensate for the deficits it entails.

摘要:

While there is a trade-off of medical sophistication for quantity of care, caused by both a desire to avoid“elitism”and a shortage of resources, China has blended traditional and modern medicine into a system that provides basic care for all. With its emphasis on prevention and on use of paramedical personnel, the Chinese model may well hold important lessons for other developing nations at a similar stage in their history.
