Lethbridge Herald (Newspaper) - January 7, 1971, Lethbridge, Alberta Your horoscope By Jeane Dixon FRIDAY, JAN. 8 Your birthday today: This is to be a year of experiments, new ideas, changing conditions. Your hatf.ts loosen up into more informral behavior, with less waste of motion. Emotional ties are apt to become more intense or, in some few instances, shunned altogether. Declutter your home and daily living of all that has outlived its usefulness, as quickly as you can. Today's natives experience special exposures to strife and limitations, may be very moody' ARIES (March Zl-April 19): An unorthodox approach pays off well Take the initiative, gather lively minds about you, get new projects started. Repair and maintenance can be accomplished quickly. TAURUS (April 20-May 20): An extra search will show you a line of action that pays better. An original idea brings you* more r e s p o n sibilities and, hopefully, increased earnings. Wait for nothing and nobody. GEMINI (May 21  June 20): Fresh information comes to you, requiring serious attention. Take the time to do it justice. There are many petty irritations to ignore or take in stride. Andy sends a complete 20-volume set of the World Book Encyclopedia to Janet Simmons, age 13, of Winnipeg, Manitoba, Canada, for her question: Exactly how dangerous are telephone wires? If you really like young children, you understand that at times they need an older friend to state a firm "Beware" -with no ifs, ands or maybes. Detailed explanations may confuse young minds and ruin the point of a safety warning. Last October, Andy explained to nine-year-old Kathy that electric wires are risky. This is true. Janet is 13 and ready to understand some of the ifs, ands and buts. *  * Many people call those rows of stately black posts telephone poles, and assume that all their wires are telephone lines. But very often, they are owned jointly by several utility companies. So let's call them utility poles. Their actual telephone lines carry fairly weak currents ranging between 24 and 60 volts. But the same poles may carry another utility line with a voltage of 1,200 volts. This tiger usually is placed about six feet above the milder telephone lines. But even an expert ponders the picture before risking a decision as to which is which. It took the best brains of many generations to tame the mighty power of electricity. Only a trained expert knows how to control it and also the many factors that can give it an excuse to strike back. Naturally you expect a bigger shock from a stronger current. But if you touch the bare wire carrying even a comparatively mild current you get a slight shock. It makes your muscles jerk. The spasm may make you lose your balance. If this happenedto a repairman perched high on a utility pole, he could fall and hurt himself very badly or even be killed. But this expert wears gloves -to avoid splinters and also sneaky electrical tricks. True, the telephone lines have rubbery coats to insulate the small current in the copper wires. But electricity teams up with moisture to boost its shock power. On rainy days, the expert wears special rubber gloves and may stand on an insulated mat. If somebody in the know takes such precautions, surely ordinary mortals should be doubly careful. When given a suitable excuse, electricity can leap from line to line with enough power to melt the wires. It needs only a contact such as a tangled kite string. Moist air can boost the shock down the string to the ground. If ever you see your kite string about to tangle with any utility line, DROP the string and don't touch it again. Let the experts repair any damage, which may cost the electric company - and so your parents - as much as $6,-000 or more. The important thing is to remember that utility poles and utility lines should be left to experts and no one e 18 e, for they are dangerous. Kite flying in this territory is risky, especially on damp days.    More and more telephone and other utility lines are being buried safely underground. In the meantime, the utility people take every precaution to protect the sensible people from overhead lines. But nobody can help certain smarties. For example, after a trained telephone expert has installed a phone in the home, they add extra outlets and extensions of their own. Nobody can estimate the risk of such a do-it-yourself project that may be used, say, In a shower or some other moist and splashy place.

(Copyright Chronicle Publishing Co. 1971) Find key element to fight disease LA JOLLA, Calif. (AP) -Scripps Clinic researchers say they have uncovered a key element in the body's mechanism for fighting diseases and the discovery may help control such illnesses as rheumatic fever. Dr. William O. Weigle, Dr. Jacques M. Chiller and Dr. Gail S. Habicht said here that their findings explain why in certain diseases the body's natural defensive forces destroy the very tissues they are meant to protect. The researchers said they have discovered and demonstrated how two types of white cells-called lymphocytes-interact to trigger the body's system against itself, causing what are known as "auto-immune diseases." Among the diseases are rheumatic fever, rheumatoid arthritis and several dozen others. "This self-destruction process and why and how the body can suddenly recognize itself as a foreign invader has long puzzled scientists," Weigle said in an interview. Among the various kinds of white cells, he said, the lymphocytes play the most vital role in spotting viruses and germs. "Defence reactions are triggered by antigens, that os, by molecules in or on substances ranging from pollens to transplanted organs which our defence systems can recognize as foreign." DISCOVER TWO TYPES Weigle said he and his colleagues have discovered that two types of lymphocytes react in different ways. One, known as T-Lympnocyte, is supersensitive to foreign substance. The other, B-Lympho-cyte, reacts slowly. Weigle said the supersensitive T-Lymphocytes can build up a great tolerance to antigens. Some of the T-Lymphocytes, however, can lose this tolerance. Weigle said he has discovered that "very small and subtle changes in an antigen can cause" an intolerant T-Lympho-cyte to substitute for a tolerant one. When the B-Lymphocyte accepts the intolerant substitute for a partner, an auto-immune disease may occur, he said. "The evidence points strongly to this process as the mechanism which produces several dozen auto-immune diseases, among them diseases involving the brain, eyes, thyroid gland, kidneys and male reproductive organs." The new findings, he said, open the possibility of controlling some of those illnesses by injecting appropriate antigens "in sufficient amounts to restore self-tolerance to lymphocytes which have lost it." Newsman jailed BELGRADE (Reuter) -Hans Peter Rullmann, correspondent in Yugoslavia of the West German magazine Dei-Spiegel, was sentenced to six years' imprisonment by a military tribunal here Wednesday for espionage and dissemination of confidential Information. Two persons on trial with him, both Yugoslavs, received sentences of 5% years each on similar charges. CANCER (June 21  July 22): Ideas, new schedules are in the planning stage. Wait for Tuesday or Wednesday before initiating serious changes. A pleasant, sociable frame of mind gets you through till then. LEO (July 23  Aug. 22): State your position clearly; ask no immediate response. Consolidate your home arrangements, find new owners for things which no longer serve your purposes. VIRGO (Aug. 23 - Sept- 22): Intuition brings you a new path to follow Little time is available for exploration, as the day is full of details. Don't be upset if your family is at some phase of development other than yours. LIBRA (Sept. 23  Oct. 22): Some ideas arise for your own use next week, some are for experiment by others. If you speak out freely over the weekend you have a better chance to see things in perspective. SCORPIO (Oct. 23  Nov. 21): Mechanical things put into ser- vice today should wear well, particularly if they relieve you of routine chores. Begin organizing new plans; remember they need thinking through. SAGITTARIUS (Nov. 22-Dec. 21): Close out the workweek neatly. Settle everything you can. Changes are coming in a few days- Travel is favored this weekend. CAPRICORN (Dec 22 - Jan. 19): Experiment with new ideas and methods. Careful notes will help you figure things out over the weekend. Travel a bit, loosen up, try being a bit less formal. AQUARIUS (Jan. 20 - Feb. 18): Get an early start to round up more resources, better f i n a n cial arrangements. Gather friends about you for exchange of lively conversation. PISCES (Feb. 19-March 20): Bring your notebook, sketch as well as scribble. Organize your ideas for future application. It's a stimulating day. with everything near you, if you look. 1970, Newsday, Inc. LAWRENCE E. LAMB, M. D. Blood clots in arteries, veins vary in effects Dear Dr. Lamb - Could you tell me what causes blood clots? If the blood clot should lodge in the brain and there is surgery, is there a danger of recurrence? Could you mention a few preventives if there is a danger of this recurrence? Dear Reader - Blood clots form in the body from slowed circulation (stasis) - which can occur in the legs after an operation or from an inflammation or an area of injury. They can form in the heart from a heart attack, adjacent to the damaged inner muscle surface of the heart chamber. They can also develop around an artifical valve that has been put in the heart or as a result of heart surgery. Most blood clots form in the veins and the legs are a favorite place for them. The clot is sometimes released and passes through the veins to the right side of the heart. The clot moves with the circulation through the right heart and lodges in the lungs. We call this' a "pulmonary embolus." This causes chest pain somewhat like a heart attack and can cause breathlessness and sudden death. Powerful reflex mechanisms can cause the heart to beat abnormally. The patient may go into shock. Sometimes we have trouble telling the difference between a pulmonary embolus and a heart attack. Clots that form in the veins almost never go to the brain. The simple reason is they can't get through the lungs and back to the left heart to be pumped out in the arteries. There are a few very rare exceptions. Most clots in the brain come directly from the left, side of the heart and are pumped through the arteries to the brain. This means the patient has to have a disease involving the left heart, like a heart attack or heart surgery. A clot may form locally in an artery in the brain and can cause a stroke. Sometimes dots formed in the arteries in the neck, leading to the brain, are removed surgically. Actual surgery within the skull to remove clots is rarely done and only in select- Whether one clot in the brain will be followed by others depends on what caused the first one. If the individual has a lot of disease of the arteries in the brain, it is possible that other clots will develop. There are medicines that help prevent clot formations. We call them anticoagulants-substances to keep the blood from coagulating. These are also used in heart attacks to prevent the formation of clots in the heart and hopefully to prevent formation of a new clot in the arteries to the heart muscle. They are also used in patients after heart operations and in patients who develop clots in their legs from any cause. There is some disagreement on how useful these medicines are. Most heart specialists do use them at least during the early phase of the heart attack and until the patient is up and about. *   Dear Dr. Lamb - I am 42. My baby is six and we badly want another child. We have tried for a year. The doctor says there is no reason why I can't have another baby. Is there any medicine I could take? Dear Reader - Yes, there are new medicines that increase a woman's fertility. Some of the multiple births reported in recent years are the result of such medicine. Even so, it's not that simple. It takes two to tango. The best advice I can give you is that both you and your husband have a fertility study. rhundoy, January 7, 1971 - THB ICTHBRIDGE HERALD - 21 I'l \ \ 1 IS GOREN ON BRIDGE BY CHARLES H.
