IZVrf 7 mf OVLR-BOM) \ Benefi )ate* Physiologist looks to find causes, cure for hypertension By Sharon Maberry Reporter The causes of about 90 percent of the high blood pressure cases re ported in the United States are un known, a Texas A&M University re searcher says. Dr. Gerald Meininger, an asso ciate professor of physiology at the Texas A&M College of Medicine, says he is conducting research to de termine the unknown causes of high blood pressure, or hypertension. Hypertension, which affects about 58 million Americans, increases an individual’s risk of heart attack, stroke and kidney disease, Mei ninger says. “I am interested in the role of mi crocirculation in high blood pres sure,” Meininger said. “Microcircu lation involves the small blood vessels in the body.” These small vessels, embedded within the tissues of the body, con trol blood flow and delivery of oxy gen and other nutrient material to the tissues, he says. Meininger says hypertension oc curs when these small vessels be come constricted and resist blood flow. Pressure goes up because of the high resistance to blood flow through the small vessels. An abnor mal amount of constriction of these vessels seems to be a problem in hy pertension, he says. Scientists can determine the causes of only about 10 percent of the high blood pressure pases re ported in the United States, he says. Known causes of hypertension in clude abnormal activity of the ner vous system and of several circula tory hormones, he says. “In addition, there appears to be a group of mechanisms that are intrin sic to the (blood) vessels themselves,” Meininger says. “These mechanisms of autoregulation are important for normal regulation of 1 unction in these vessels.” Meininger says these blood vessels sense specific signals by the body tis sues and react accordingly to permit the correct amount of blood flow. When the vessels constrict, the in crease in pressure seems to stimulate these local mechanisms to constrict even more, he says. This amplifies the initial disturbance into a greater disturbance and blood pressure in creases. Trying to figure out what stimu lates these mechanisms to cause va soconstriction (a reduction in the size of the blood vessels) is what he’s been researching since 1981, he says. “I’ve called attention to these local mechanisms in autoregulation as contributors to the hypertensive dis ease process,” Meininger says. “My goals are to identify precisely what these mechanisms are and if various drugs can be used to manipulate these mechanisms.” Meininger says his research is im portant because when the cause of hypertension is determined, it can be cured surgically. However, when the cause is un known, as in almost all high blood pressure cases in the United States, the problem can be treated but not cured, he says. “Treatments are aimed at keeping the blood pressure down at a normal level,” he says. Such treatments include drugs that increase the size of the con stricted vessels, reduce abnormal ac tivity of the central nervous system and reduce heart action in the body, he says. Other methods aimed at control ling hypertension are weight loss, exercise and elimininating smoking, he says.

It’s been nearly two years since Guynes collapsed during a Martin High School football practice and slipped into a coma when a blood vessel ruptured in his brain. On Monday, he entered classes for the orthope- dically handicapped at Lamar High School, but that didn’t dampen his spirits. “I’m excited,” Guynes said through his mother, Kay. “It’s getting back to a normal life.” He was injured during a “machine gun alley" fooifl drill in which a player must block a string of otherpb ers running at him one after another. Guynes,at fensive back, was in a coma for 10 months, andrecott has been slow and often painful. Guynes said he always knew he would be bad school one day, hut never thought it would take sob to prepare.
