European Stars and Stripes (Newspaper) - November 14, 1993, Darmstadt, Hesse                                Sunday november 14. 1993 . The stars and stapes Page 11 ultraviolet rays on Rise study says Washington a scientists in Canada have detected an increase in ultraviolet radiation that in part May be caused by the Man made thinning of atmospheric Ozone. But a searchers said the added solar rays Are unlike by to pose a health danger. . Kerr head of an Ozone monitoring group for the Canadian government said instruments in Toronto have detected seasonal increases of up to 35 percent in ultraviolet radiation. Kerr said the finding reported Friday in the journal science was important because it links for the first time in North America an increase of us a radiation and the thinning of Ozone. There should be concern about seeing a change that we Haven t seen before Kerr said but he added that the change is so slight it is not an immediate  forget going cold Turkey smokers told Atlanta a tapering off May top going cold Turkey when it comes to quitting cigarettes addiction researcher reported saturday. Those who can delay the Day s first cig Arette or give up smoking for seven Days have a Good Chance of eventually drop Ping the habit for Good according to a new study. " maybe put goal should t be to get them to auit said study author John p. Pierce of the University of California san Diego. Maybe our goal should be to get the to quit for at least a week or to get them under it cigarettes a Day he said at meeting of the american society of addiction  study provides a new View of quit Ting in which smokers Are encouraged to make Progress by smoking less and quit Ting intermittently rather than making the difficult Choice to Stop immediately. A no smoking program designed forthe state of California was based on Pierce s findings and has enabled 26.7percent of smokers to quit roughly twice the rate of those quitting without the pro Gram said Shu Hong Zhu another a cd researcher who helped develop the  key feature of the program was repeated follow up Calls from Counselor without such follow up doctors advices useless Pierce said. Pierce also found that restriction of smoking at Home and in the workplace was a Factor contributing to successful quitting when combined with assist Ance like that in the California no smok ing program. David Abrams of drown University i Providence r.i., is a authority on smok ing cessation and praised Pierce s  said it confirms an emerging View that quitting is often a gradual pro Cess. He also said that the measurement period of four years is too Short to prove there is a trend toward in creasing us a radiation and that the increase May have been caused partially by a 1991 volcanic eruption. Ozone is a Gas composed of molecules that have three atoms of oxygen. The Gas acts As a shield against us radiation from the Sun. Atmospheric studies have reported Over the last few years a slow erosion of the Ozone layer. This in part has been blamed on Industrial chemicals particularly chlorofluorocarbons that break Down the Ozone molecule and that persist in the atmosphere for decades. Us a radiation is made up of the solar rays that can bum the skin. Lifetime doses of us a also Are thought to play a Rote in developing skin cancer. The radiation also is known to have other biological effects such As killing or retarding the growth of some microscopic organisms. Because of the effect on natural Ozone production of chlorofluorocarbons or rfcs will be stopped in most Industrial nations in 1996 under an International agreement called the Montreal protocol. Kerr said that the increase in us a detected by the Toronto instruments is so slight that it s unlikely to have any biological  John Frederick an atmospheric scientist at the University of Chicago agreed. Frederick said the Canadian study is important because it is the most careful ground level measurement yet of us a radiation in North America. He said it also gives new evidence supporting the theory that a thinning Ozone layer can cause an in crease in ultraviolet radiation. Although he said the us a increase was a change in the wrong direction Frederick described it As a Small effect.

Bal xxi deflated artery a balloon Catheter is placed inside partially blocked artery wires effective the balloon Catheter is expanded. The plaque is pushed against the arterial wait after the balloon Catheter has been removed the artery remains fully open restoring the blood flow. The blockage is gone for years or possibly forever. Coronary artery bypass blocked coronary arteries which carry blood to the heart from the Aorta Are bypassed by using a graft of a vein from the patient s leg. Sources r Aorta blocked coronary vessel a we j. Castilo Tom Holma m near surgery to open arteries Atlanta a tiny wire coils that prop open arteries can reduce significantly one of the most  expensive problems of hear treatment the frequent failure of balloon angioplasty two major studies show. More than 300,000 americans undergo angioplasty annually to open clogged heart arte Ries and relieve Chest pain. About 40 percent of the time however the arteries squeeze shut again within a few weeks. When this happens doctors must repeat the angioplasty which typically costs $10,000 to $20,000 per patient or perform even More expensive coronary bypass surgery. Finding a Way to reduce this complication what doctors Call re stenosis has been a major focus of research. At the annual scientific meeting of the american heart association . And euro Pean doctors on thursday presented the re sults of comparison studies showing that stems or the coils which resemble the Spring sin ballpoint pens can reduce the re stenosis rate by about one third. These Are fantastic numbers. It seems quite convincing commented or. John Simpson of Sequoia Hospital in Redwood City Calif., who moderated the session where the data were presented. As with Ordinary angioplasty Doc tors first Force open the clogged artery by blow ing up a balloon and then deflating it. In the new approach they leave behind the Stem keeping the artery from closing up. In the two studies doctors tested a stent thatis made by Johnson & Johnson which partially financed the work. However he and others cautioned that stent still carry one major drawback that will limit their use unwanted bleeding. The stents at tract blood clots so doctors must give patients High doses of blood thinners for a few Days. This caused bleeding complications in about 10 per cent of patients in both studies.
