...visiting doctor at the A.M.A. meeting had just had a little blood drawn from his arm. He watched while a technician dropped the specimen into the machine. Within a minute, he saw pastel-colored samples of his diluted serum being pumped through a dozen spaghetti-thin plastic tubes. Lights began to flash on and off, and a mechanical pen started to trace a red line on a chart. The doctor noted with equanimity that the thin red line passing through the columns of the chart was reporting normal amounts of calcium, albumin and cholesterol in his blood. Then...
...research physicians and Technicon technologists, the autoanalyzer performs many delicate and highly sophisticated chemical and physical tasks in less time than it takes to describe them. First, the 3-milliliter blood sample (less than a teaspoonful) is centrifuged to get rid of the cells; the analyzer works with the serum that remains. The machine divides the serum into twelve portions and sends them racing through the plastic tubes by power from roller pumps...
Along the way, every sample is appropriately diluted and mixed with a specific reagent for each of the twelve tests. The resulting rivulets are variously colored, according to the reagent used and the interaction between reagent and serum...
...catalogue of drugs that cause severe or fatal breakdowns in the blood-forming mechanism, Dr. Moser reminded his audience that one of the worst drug offenders of all remains one of the most valuable lifesavers available: penicillin. It is known to set off an infinite variety of allergic or "serum sickness" reactions, and causes up to 300 U.S. deaths a year. Even the mildest of drug-induced difficulties, he added, should not be minimized, for the side effects are not limited to one generation. If a woman has certain radiopaque dyes injected for gall-bladder X rays, for example...
...doctors report in Science that this electrical inactivation occurs before myelin destruction, is surprisingly rapid and, most important, is readily reversible-at least in the test tube. Washing with healthy serum or simple salt solution restores the normal electrical activity. This, the doctors suggest, may explain the early, unpredictable phase of multiple sclerosis...
