After the lackluster Montreal performance, many countries may be tempted to bypass GATT and negotiate more bilateral or regional pacts with only a few trading partners. Still, no one is quite ready to abandon GATT. Says Bill Martin, chief economist of Phillips & Drew, a leading London brokerage firm: "There's not great hope that GATT can achieve much in the way of further trade liberalization. But GATT is a very important bulwark against galloping protectionism." An important bulwark, but an increasingly leaky...
...therapy. A 55-year-old former printing-plant foreman, Michael and his brother Daniel, 58, a retired barber in Canonsburg, Pa., have a genetic disorder that results in very high levels of LDL and low levels of HDL. Daniel has suffered a heart attack, and both brothers have had bypass surgery. Now the Brunos are on low-saturated-fat diets and are taking lovastatin. In addition, Michael is taking gemfibrozil. Since the brothers started their programs, Michael's total cholesterol has fallen from 224 to 184, and Daniel's from 325 to 201. Both brothers' HDL levels have gone...
...artery walls, can high levels of HDL reverse the buildup of plaque? There are indications that this may be the case. Last year Dr. David Blankenhorn, director of atherosclerosis research at the University of Southern California, reported on a study in which 162 nonsmoking men who had undergone coronary- bypass surgery were put on a low-fat diet; 80 of them were also treated with niacin and colestipol. Among the drug-treated group, HDL levels increased 37%, while LDL decreased 43% and triglycerides went down 22%. Blankenhorn found evidence that arterial disease had been halted in 61% of the drug...
...study showed that obstructed arteries benefited most from decreased LDL. Lower levels of triglycerides, he found, may also play an important role, a possibility that has emerged from other studies as well. At Baylor College of Medicine in Houston, Dr. Antonio Gotto Jr. discovered that his heart-bypass patients "almost without exception" have lower levels of HDL and slightly higher levels of triglycerides than people without heart disease. One theory is that excess triglycerides somehow mark HDL particles for elimination by the liver. When this occurs, says Gotto, "there is this Pac-man in the liver chewing...
...When arteries to the penis have become constricted, surgery can sometimes restore blood flow. In one operation, called an endarterectomy, the blood vessel is opened and scraped clean. Doctors also bypass blockages by grafting sections of an abdominal artery around narrowed branches of the iliac artery that lead to the penis. This operation is similar to the one done on clogged coronary arteries, but does not have as high a success rate. Vascular surgeon Ralph DePalma of Washington thinks that vessels to the penis are more fragile because they are subjected to sudden surges in blood pressure...
