...highly concentrated, and the machine dilutes it with as much as 35 times its own volume of water to get the right mixture for each patient. Patients still have personalized equipment at their bedsides: pumps to deliver the right amount of fluid from the monster, and the sandwich-like filter...
...potential causes of cancer. Most early tests were on the backs of mice be cause the skin there is of the same cellular class as the inside of a man's lung. More recently, to study an approximation of what happens when smoke rushes past the tiny, hairlike filter system (cilia) of the human respiratory tree, the researchers have taken to using parts of the gills of hard-shell clams...
...first big gain, Drs. Wynder and Hoffmann find, comes from filters. "The smoker of filter cigarettes of 1964 is on the average exposed to approximately 50% less tar*and nicotine than he was while smoking cigarettes without filter tips ten years ago," they reported. Contrary to gloomy prophecies that smokers would cancel out the benefits of filters by puffing more of the newer cigarettes, the researchers found that in general this has not happened...
...components of smoke that paralyze the cilia, and are therefore important in bronchitis and related diseases, are largely carbolic and other acids. A proportion of these (up to 90% in the case of phenol) can be removed by cellulose acetate filters. Other cilia-damaging components, such as acetaldehyde and acrolein, are cut down by an activated charcoal filter, especially if the charcoal is compressed. A still better way, said Wynder and Hoffmann, is to filter the smoke through water and then through compressed charcoal, but so far this is not practicable -except, conceivably, in homes with filter-tipped hookahs...
...Stark, with an exhausted expression, says that "she'll drive you bats with too much analysis. It's not arrogance, but doubt. She is like a barracuda. She devours every piece of intelligence to the bone." One of her actor friends says that "she is like a filter that filters out everything except what relates to herself. If I said, 'There's been an earthquake in Brazil,' she would answer, 'Well, there aren't any Brazilians in the audience tonight, so it doesn't matter...
