   Kokomo Tribune (Newspaper) - May 8, 1994, Kokomo, Indiana                                Science medicine 68 Sunday May Kokomo tribune bo found near South Pole WASHINGTON AP Polar plains ndw scoured by frigid winds and sub zero temperatures were warm enough 200 million years ago to be home to large meateating dinosaurs according to researchers who unearthed fossils of a new species Williaih Hammer of Augustana College in Rock Island reports today in the journal Science that fossils of a previously unknown dinosaur were found on an Antarctica mountainside 400 miles from the South Pole Hammer led an expedition that braved 25 degreebelowzero temperatures to dig out pounds of fossilbearing rock The fossils have now been assembled to reveal a meateating dinosaur with a distinctive bony crest on top of its head We called it Cryolophosaurus ellito or frozen crested Hammer said Thursday Thats because its got a crest on its head and we almost froze to death collecting The animal measured about 25 feet in length and stood about 12 feet high when it walked on its large hind legs It had small forefeet a long tail and powerful jaws armed with rows of sharp teeth said Hammer Its appearance is similar to a group of dinosaur meateaters called allosaurus But the crested reptile was unique because of its location and the age in which it lived This is the first dinosaur find on the mainland of Antarctica and is the high est latitude said Hammer They fossils were only about 400 miles from the South This shows he said that Antarctica then had a climate mild enough to sup port large animal life including herds of planteaters that would be the prey of the crested reptile He said the climate of the area then probably was similar to that of northern California Oregofl and Washington Mixed among the bones of the meat eater said Hammer Were leg and neck bones from a prosauropod a type of planteating dinosaur that has been found on other continents This indicates to us that this thing was probably feeding on a herbivore skeleton when it said the scientist Strokes cost nation a bundle billion per year study says WASHINGTON AP Strokes cost the nation at least billion a year but the bills can range from to a patient and dont always correlate with sur vival a new study says Why the disparity Thats the study author Dr David Matcher of Duke University said Wednesday We are now trying to under stand the relationship between what we do what it costs and what it Strokes are the nations third leading killer after heart disease and cancer They strike some people a year killing and leaving others unable to move or even speak They are caused when a blood clot or fatty deposit blocks an artery or a blood vessel hemor rhages in the brain killing brain cells No approved treatments exist to stop a stroke all doctors can do is help patients recuperate The National Stroke Association said Wednesdays study is the first to put a price tag on strokes and found they cost more than all other illnesses except heart dis ease and The study commissioned by the federal Agency for Health Care Policy and Research and unveiled at a neurosurgery conference here analyzed 1991 Medicare records of stroke victims It concluded that medical care rehabilitation and lost productivi ty cost billion in the first three months the time when prob lems could be positively attribut ed to stroke The average medicaPcost per patient was Bills ranged from to a high of in some severe cases One in 10 patients had bills of more man Nationally 11 percent of patients died during their initial hospitalization After three months 20 percent had died Fortyfive percent left the hospital for a rehabilitation center or nursing home Regionally researchers discov ered Mortality was lowest in New pngland percent and highest in the Mountain region from Montana to Utah at percent But both regions spent an average of per patient Of stroke victims who live 42 percent in the Central Northwest region from North Dakota to Kansas returned home compared to 62 percent in the Central Southeast Kentucky Tennessee Alabama and Here the Central Southeast region spent about more per patient Regionally states spent from an average low of per patient to an average high of Rural areas spent about per patient compared with in cities Differences in stroke severity and overall health cant entirely explain the cost and survival dis parities so scientists now are looking at doctors practices Matchar said Stroke costs are one part of the fiveyear study Doctors now will figure out which treatments offer victims the best chance of recov ery at the best price Theyll also concoct a strategy to prevent strokes determining the effectiveness of stroke education ajjd interventions like aspirin therapy to fight blood clots and spgery to clear fatclogged arter ies At the time the animal lived Antarctica was still attached to other southern conti nents A process called continental drift caused the large land masses to slowly separate from a single body over millions of years Hammer estimates that the site of his dig was at about 65 degrees south latitude 200 million years now is at about 85 degrees Hammer said the fossils may help fill a gap in tracing the evolution of dinosaurs This is early in the Jurassic which is pretty early in the evolution of he said It shows that carnivores got large and evolved Very The age of the animal was determined by geologists who dated rocks found just above the fossils This is a spectacular hew said Paul Sereno of the University of Chicago Its really the first good look weve had at what existed in Antarctica during the Jurassic The find is important not only for understanding dinosaurs he said but also for studying the ancient climate This is a highly significant said Mike Parish of Northern Illinois University It is an animal new to science It opens up a whole new chapter in our under standing of Science which published the study is the journal of the American Association for the Advancement of Science Looking through the glass Jesse Lemke 12 gets a different view of the world as he experiments with a water prism after school at Haskin in Sandwich recently Many of the toys available in his sixthgrade class are related to science AP photo Heart rhythm problerns on the CHICAGO AP Survivors of heartrhythm abnormalities seri ous enough to put them in the hospital shouldnt drive again until at least eight months after ward when their risk of repeat episodes is lower doctors say Such abnormalities called arrhythmias bring sudden death to about Americans each year In episodes of the worst arrhyth mias which strike the hearts main pumping chambers people almost always faint The likelihood of repeat episodes declines with time to about a chance per month after seven months Oregon doctors found That is about the same risk as the actual accident rate among motor vehicle drivers overall in Oregon where the study was done said Dr Greg C Larsen the lead author and a cardiologist at the Portland Veterans Affairs Medical Center The study is published in The Journal of the American Medical Association Its important to recognize that were comparing apples and Larsen said in a tele phone interview Monday We looked at arrhythmia events that could to accidents not at actual But doctors currently have no yardstick at which to base recommendations about when arrhythmia patients should resume driving and state restric tions vary widely he said A 1991 study found that 26 states regulated driving by people who had lost consciousness other than because of seizures and the length of driving restrictions ranged from six weeks to 18 months Only eight states specifically regulated driving by people who had suffered fainting spells caused by arrhythmias me study found The states are all over the lot on said Mike Brqwnlee associate administrator for traffic safety programs at the National Highway Traffic Safety Administration Usually states are guided by their own medical boards he said Monday He did not have an updated overview of state regula tions Jane Roemer executive director for public policy at the National Safety Council said her group has no position on the matter Data on crashes caused by arrhythmias and other medical problems is scant she said Altogether we would find the number of crashes and fatalities due to those kinds of things would be very small compared to the causes we know such as alco hol abuse not wearing a seatbelt she said Monday from Washington Larsens team studied 501 sur vivors of the two potentially lethal types of arrhythmia ventricular tachycardia and ventricular fibril lation who were cared for by the Oregon Health Sciences University Arrhythmia Service between August 1978 and October 1989 Patients were tracked for a year because most arrhythmia sur vivors decide within the first year whether to drive again they said During the followup 17 per cent of the 501 patients experi enced episfades that could impair their driving ability the researchers found The risk was percent in the first month then dropped to about percent per month in the second through seventh months then to about percent in months eight through 12 they said It would make sense to restrict driving for most survivors qf arrhythmia for seven months they said Eat your carrots Forget those beta carotene pills By BARBARA DESKINS Pittsburgh PostGazette Are you confused about beta carotene If so you are not alone Even distinguished members of the nutrition community are puz zled by the findings in a recent study The study in question was pub lished in the April 14issue of the New England Journal of Medicine Sponsored by the National Cancer Institute and the National Public Health Institute in Finland it involved Finnish men 50 and older all of whom were longtime smokers The men were divided into four groups one took vitamin E alone one took beta carotene a third group took both nutrients and the fourth group took a dummy pill or placebo The sub jects consumed these supplements for five to eight years Researchers found no evidence that beta carotene can protect against cancer and heart disease In fact it may have harmful effects as the men in the group taking beta carotene were more likely to die from lung cancer and heart disease The results from ingesting vitamin E were less sig nificant and could be due to chance the investigators The reason the experts are puz zled comes from comparing these findings to other recent studies in which beta carotenerich foods were examined For example Boston researchers studying the diet of more than found that those who ate five or more serv ings of carrots a week were 68 per cent less likely to suffer a stroke than those who ate just one serv ing a month In another study men who con sumed 200 grams of carrots daily about large carrots for three weeks had their serum cholesterol lowered by 11 percent And studies on a group of men in New Jersey showed that the consumption of dark yellow orange vegetables carrots sweet potatoes and winter squash more consistently predicted a reduced risk of lung cancer than eating any other food group In all of these studies it Was suggested that the reason the foods exhibited a protective effect was because Of their high antioxi dant content particularly beta carotene What is beta carotene Beta carotene is the pigment responsi ble for the typical orange color of vegetables and fruits including carrots pumpkin apricots sweet potatoes and winter squash It is also present in dark green vegeta bles such as spinach and broccoli though the orange is covered up by the green color of the chloro phyll Because of its ability to color beta carotene is often used as an additive in foods such as mar garine which has about 4 mil ligrams added per pound so it will look more like butter Until now beta carotene has been considered a harmless sub stance so that taking large quanti ties in supplement form was not thought to be dangerous though it can turn your skin yellow as it did in about a quarter of the Finnish men who were taking 20 milligrams of beta carotene daily The human body can convert about half of the beta carotene ingested into vitamin A a nutrient necessary for healthy skin and mucous membranes that line the inner cavities of the body Vitamin A is also required for proper vision But the current intense interest in beta carotene as well as two other nutrients vitamins C and E focuses on their ability to act as antioxidants Antioxidants are thought to be able to destroy free which some scientists theorize not only accelerate aging but also contribute to the forma tion of cancers and cataracts as well as initiating the buildup of fatty deposits in the arteries Free radicals are chemical com pounds formed during the normal functioning of the body and the antioxidants are believed to be able to mop up these chemical vandals thus reducing their potential for damage to body cells Nutritionists have preached that the best way to obtain vitamins is by consuming them in food but recently a number of them have cautiously begun to suggest that perhaps supplements are all right maybe even beneficial Americans have heard them and are swallowing antioxidant pills in everincreasing numbers Sales of beta carotene for example rose by 31 percent in 1993 alone But the latest Finnish study casts doubt on whether reaching for the supplement bottle to ward off chronic disease and the progres sion of aging is such a good idea Research continues on the role of antioxidants in slowing down aging as well as preventing killer diseases Many clinical trials are in progress and these studies will continue to fill in pieces of the nutrition puzzle in years to come Based on what we know today it makes a lot more sense to reach for the bag of carrots instead of the beta carotene pills 3RD Annual Turn Around Breakfast May 12 Kokomo Country Club 1993 Turnaround Breakfast The Howard County Turnaround Council will recognize Howard County Students at a special awards breakfast who
