...good housekeeping is scarcely older than her column. "I didn't know you had to clean a John until six months after I got married," says she. Once, before guests arrived for a garden party, she dressed up brown spots on 'her lawn with green vegetable dye. But her homely hints are usually followed to the letter: when she recommended putting a cup of water inside a turkey to keep it juicy while roasting, some readers obediently stuffed their birds with both cup and water...
...that week had gone hundreds of thousands of man-hours. For more than a month before, workers on double shift had labored at constructing the stands in front of the Capitol. No detail was overlooked. The National Park Service, seeking to achieve a touch of spring, sprayed fresh green dye on the lawns surrounding the Lincoln Memorial. Trees along the inaugural route got a light coating of Roost-No-More, a compound guaranteed to put Washington's pesky starlings to flight. Secret Service agents battened down manhole covers on the right of way to forestall any bomb-planting saboteur...
Arteriograms (Xray still photos of arteries that have been flooded with radiopaque dye) help, but they are not always reliable: the "flooding" technique often fails to fill the arteries with enough dye, and still pictures do not clearly separate small vessels that are superimposed on each other. One of the major breakthroughs at last week's AHA meeting came when the Cleveland Clinic's Drs. Earl Shirey and F. Mason Sones Jr. demonstrated a diagnostic technique that seems likely to improve on the arteriogram-a method of coordinating the ray, a specially designed catheter and a movie camera...
Monitoring the operation through an image intensifier-a refined fluoroscope that produces an X-ray image 1,500 times Drighter than the old-style fluoroscopic screen-Drs. Sones and Shirey then release a tiny amount of radiopaque dye through the catheter into the aorta in order to locate the spot at which right and left coronary arteries join the circulation's main stem. "The rest," says Sones, 'requires only a little bit of simple dexterity." The catheter is successively slipped into both coronary arteries, and small injections of dye (2 cc. to 5 cc.) are sufficient to silhouette...
...Bertram Selverstone has devised a daring and ingenious technique. First, Dr. Selverstone opens the way to the Circle of Willis by taking out a big flap of bone from the skull. (An arteriogram-an X ray of the brain's blood vessels involving the injection of radio-opaque dye into the patient-will have already spotted the site of the aneurysm.) Then, using an artist's airbrush, Selverstone sprays the aneurysm with a mixture of plastics that combine to form a coating similar to Saran Wrap. This is tough, but too thin to give full protection against further...
