Page 2 - The Michigan Daily - Friday, March 28, 1986 4 New heart attack treatment found By LISA DRESNER A University cardiologist has con- cluded that using a balloon to open restricted arteries for the treatment of heart attacks is more effective than using a drug which has been standard treatment for several years.' Dr. William O'Neill, an assistant professor of internal medicine, says in the March 27 issue of the New England Journal of Medicine that the balloon technique, known as angioplasty, is superior to the stan- dard drug used to treat heart attacks - streptokinase - because the balloon not only removes blood clots blocking the flow of blood to the heart, but also alleviates the underlying cause of the heart attack: the buildup of plaque or cholesterol on the walls of the heart arteries. "THE DRUG is useful for dissolving blood clots that are often the immediate cause of a heart at- tack, but the underlying obstruction in the artery is still there," O'Neill said. Because streptokinase does not remove the build-up of plaque with the clot, blood flow to the heart may still be restricted, leaving the patient at risk for a future heart attack. O'Neill said that when the restriction from plaque is opened by angioplasty, the risk of another heart attack is greatly reduced. Heart attacks usually occur when a blood clot develops where an artery supplying the heart muscle is narrowed by plaque. The blood clot blocks the flow of blood to the heart muscle, and if the blood flow is not quickly restored, permanent damage to the muscle may occur. O'NEILL and his colleagues studied 56 patients who were treated within 12 hours of a heart attack with either angioplasty or streptokinase. The study compared the immediate effec- ts of the drug and balloon therapies with their long-term results, and although both techniques were equally effective in initially opening blocked arteries, their long-term results differed greatly. For the patients successfully treated with streptokinase, the restriction narrowing the artery was still present in 83 percent of the cases. For the patients successfully treated with angioplasty, however, the dangerous restriction remained in only 4 percent of the cases. O'Neill said the most effective treatment for heart attacks is likely to be angioplasty in combination with clot-dissolving drugs. Angioplasty, a technique formerly used by cardiologists as an alter- native to elective bypass surgery, uses a tiny plastic balloon attached to the end of a long thin tube. The tube is inserted into an artery in the leg, and pushed through the artery until it reaches the clot near the heart. A wire in the tube is used to pierce the blockage, and the balloon is then inflated to compress the plaque against the wall of the artery and restore blood flow. The plaque is squeezed out of the way, and the walls of the artery expand to form an adequate opening. The plaque tends to remain compressed against the wall, O'Neill said. In cases where the restriction does recur, another angioplasty treatment usually solves the problem, according to O'Neill. O'Neill, the director of the cardiac study unit at the University's medical center, is now conducting a three-year follow-up study of the long-term benefits of emergency angioplasty. Law puts limits on servants WELLESLY, Mass. - From the quaint shops downtown to the rolling hills of the country club golf course, most residents of this posh Boston suburb seem unfazed by a new bylaw that limits homeowners to two live-in servants. "We haven't received any com- plaints from residents and we don't expect any,"said Jeanne Dickey, a secretary in the building inspector's office. "Nobody has said 'boo."' MS. DICKEY and town officials point out that the new bylaw, ap- proved unanimously by about 200 residents at the annual town meeting Tuesday, was not designed to penalize homeowners with mansions filledwith maids and butlers. On the contrary, it was designed to crack down on those without servants in this suburb 15 miles west of Boston wher th nereantwiest of Bs A fter w ords $18,355, one of the highest in the state. The rationale behind it is that Quality Books at uncommonly low prices groups of unrelated people, many of them students and young people, are *getting together and renting an entire house and they say any number of them are servants.

OPEC unable to reach agreement as price drops (Continued from Page 1) target countries. The embargo resulted in much higher crude oil prices. THROUGHOUT THE 1970s, OPEC successfully manipulated the price of oil. The organization provided such a large percentage of the world's oil that it was able to control the price by changing production levels. Typically, each member nation would be given a production quota, and Saudi Arabia was the "swing producer" that modified its production to make sure OPEC met its overall production quota. As oil prices rose, new producers such as Great Britain entered the market to share the profits. As OPEC's share of the market slipped, some OPEC nations began cheating on their quotas to increase their profits. As a result, Saudi Arabia was forced to cut further and further back on production to maintain OPEC's quota. SAUDI ARABIAN frustration grew until last summer, when the King of Saudi Arabia said that unless other OPEC nations shared in production cutbacks, Saudi Arabia would "turn the spigots on," according to Salant. When the other nations failed to reach an agreement, Saudi Arabia followed through on its threat. The ensuing increase in supply caused the recent fall in prices. But in the same way that the Saudis caused the current glut, "they could turn it around tomorrow if they wanted," Salant said. At the meeting last week, OPEC in- tended to reach an agreement on production cutbacks. The member na- tions, however, could not decide how they should divide the cutbacks among themselves. Salant would not offer any predictions about the direction of the oil market, saying that such a forecast was too difficult to make. He did say that if the low oil prices continue, producers will begin to drop out of the market because it would no longer be profitable for them to pump oil. In such a scenario, Salant said, Saudi Arabia could hold out the longest because it can produce oil more cheaply than any other nation. WEEKEND MAGAZINE Fridays in The Daily 763-0379 IN BRIEF COMPILED FROM ASSOCIATED PRESS AND UNITEb PRESS INTERNATIONAL REPORTS Israeli jets hit South Lebanon; PLO rockets Israeli town NIYEH NIYEH, Lebanon - Israeli warplanes bombed Palestinian bases near the southern Lebanese port of Sidon Thursday, killing 10 people and wounding 30 shortly after a rocket attack on an Israeli school wounded three Israeli pupils and one teacher in the border town of Qiryat Shmona. The Sidon camps are strongholds of Yasser Arafat's Fatah guerrillas, the main fighting group in his Palestine Liberation Organization. They were the first Israeli casualties of rocket fire from south Lebanon since Israel invaded its northern neighbor in 1982 in an effort to drive out Palestinian fighters. The raid was clearly intended to warn the Palestinians, who have been building up forces in the area, to expect similar retaliation if cross-border attacks continue. Many Arafat loyalists have been returning to the Sidon area. A Fatah leader, Badi Abu-Suleiman, claimed responsibility for the rocket attack on Kiryat Shmona, and vowed while inspecting the damaged buildings: "We shall continue in our struggle against the enemy and shall retaliate in a violent way...inside occupied land." Senate passes Contra aid bill WASHINGTON - The Senate yesterday revived President Reagan's plan to send $100 million in aid to Nicaragua's Contra rebels, the legislation now goes back to the House, where it was rejected just days before a Sandinista raid into Honduras. As approved by the Senate, the measure would send the money to the Contras but under the condition that no offensive weapons can be sent for 90 days in order to give peace negotiations a chance. That was the provision agreed to by Reagan last week in a last-minute bid to win House approval. But the House rejected his plan, 220-210, a week ago. Since then, the political situation changed because of what the White House called an incursion by 1,500 Nicaraguan troops into neighboring Honduras. Reagan's plan would give the Contras $70 million in military aid and $30 million in non-lethal help in their effort to oust the Sandinistas. The current U.S. aid package, which expires Monday, contains $27 million.in non-lethal assistance, including uniforms and medicine. The vote was 53-47. Libyans demonstrate against U.S., give support to Khadafy TRIPOLI, Libya - Marching bands led hundreds of Libyans through the streets of the capital last night in support of their leader, Moammar Khadafy. Signs bobbing in the crowd said "To Hell With America." The official news agency JANA said Walid Jumblatt, Lebanon's Druse Moslem militia leader, had offered "suicide squads" to help carry out Khadafy's threat of attacking U.S. "terrorist embassies" and other American targets. State media issued calls for such action Wednesday in revenge for the U.S. Navy's actions earlier this week in the-Gulf of Sidra. In a related development, the Libyan ambassador to Italy, Abdul- Rahman Shalgam, said in Rome that Libya would not retaliate against U.S. military bases in Europe or American citizens in Libya or other Arab countries. Khadafy's aides summoned foreign journalists to a meeting today morning. The capital was rife with rumors that Col. Khadafy would sail out into the gulf as if chasing off the U.S. 6th Fleet. Trade deficit decreases 24% WASHINGTON - The United States trade deficit fell to $12.5 billion last month, a dramatic 24 percent improvement over the January total as the country's oil bill declined sharply, the government said yesterday. Analysts said the turn-around offered hope that the darkest days for U.S. trade are coming to an end, but they cautioned against4eading too much into one month's numbers. At the White House, presidential spokesman Larry Speakes hailed the new report as signaling "the start of a fairly steady decline in the trade deficit." Speakes said the drop in the value of the dollar "is just now showing up in the trade figures and should help the trade picture at least through 1986." The Commerce Department report said the February deficit was down from a record $16.5 billion imbalance in January. Last month, imports fell 9.7 percent to $30.2 billion while exports rose 4.3 percent to $17.7 billion , their highest level since June. Anchorage volcano erupts ANCHORAGE, Alaska - Augustine Volcano began a pulsating erup- tion yesterday, pumping smoke and ash more than nine miles high and spreading it toward Alaska's major population center, scientists said. The Coast Guard, fishing boats and residents of the coastal community of Homer reported the mountain came alive about 2 a.m., said Tom Miller, a USGS vulcanologist. "They're reporting orange fire, smoke and flashes," Miller said. The USGS monitoring stations on the mountain recorded an "intense micro- earthquake swarm" beginning about midnight, he said. State seismologist John Davies described as modest the eruption of the 4,025-foot peak which forms its own uninhabited island in Cook Inlet, about 175 miles southwest of Anchorage. "In layman's terms, it's been erupting since midnight, but what we've observed from seismic records is that the eruption waxes and wanes," he said. "You have a major eruptive event that lasts for an hour or so, and then subsides." , he Mtichigan Bai1 Vol. XCVI - h:90 The Michigan Daily (ISSN 0745-967 X) is published Monday through Friday during the fall and winter terms.
