Galesbur ster- Golesbur Wednesda By LAWRENCE LAMB, M.D. Dear Dr. Lamb — Is a woman protected from high cholesterol levels by estrogen? I mean a woman of 39 with a high cholesterol level of 380. How many sex hormones does a man and woman have? Dear Reader — Ordinarily during the childbearing years a woman will have a lower cholesterol and lower bloodfat lev- male hormone. With the de crease in the amount of female hormones and sometimes the associated increase in the amount of male hormones pr< duced, these changes can occur. Dear Dr. Lamb — It has occurred to me that I have never heard of a case of heart cancer, although you hear of it striking almost every other part of th body. Could it be that if someone does have cancer of the el, and she gets some protection against the development of fatty deposits in the arteries which) heart is somewhat immune to lead to heart attacks and other heart it is labeled under heart disease? If it is true that the problems. This isn't always true. If the woman has liver disease, gall bladder disease, kidney disease, diabetes or certain , inherited metabolism diseases, she may have a high cholesterol level anyway, and such high levels from any cause may contribute to the development of fatty deposits in the arteries, with an increased tendency towards heart attacks and other problems. If the blood fat and cholesterol levels are too high in a woman during childbearing years, the cause needs to be looked for, and it needs attention just as much as it does in a man., Women have two main fexale sex hormones, estrogen and pro gesterone. They also produce the male hormone, testosterone. It is the ratio of these that determine her femaleness. The same can be said for men. The main sex hormone for men is testosterone, but even the testicles produce estrogen and related hormones. The maleness of the individual is dependent on the ratio of male to female hormone. This is part of the reasor why women, after the menopause, begin to develop facial hair and changes which are more commonly attributed to cancer, could this immunity somehow be used in finding a cancer cure? Dear Reader — Thank you for your thought. Unfortunately, cancer of the heart does occur. It is rare. Although it does occur, cancer of the muscles in general is relatively rare compared to cancer of the skin, digestive tract, lungs, reproductive organs and breasts. The heart really is a specialized muscle. With the exception of the reproductive system (prostate, cervix, uterus and breasts), the most common sites for cancer are those which are exposed to environmental factors. The gestive tract to the foods eat, the lungs to the air and its contents that we breathe, the skin to sun, wind and air. This should say something about the importance of environmental factors in cancer. It also suggests preventive measures may be important. A classic example smoking. Less than 10 per cent of lung cancers occur in non smokers. If everyone quits smoking cigarettes tomorrow, the incidence of lung cancer would be sharply decreased. In other words, preventive measures would significantly decrease lung cahceh (Newspaper Enterprise Assn.) • * 4 Pacemaker Is Rechargeable WASHINGTON (UPI) - A rechargeable artificial pacemaker for heart patients has been developed by Johns Hopkins University scientists. The pacemaker is a muscle which regulates heartbeat. About 150,000 people in the world how use artificial pacemaker to regulate their heartbeats. One drawback has been that the patients need surgery and hospitalization about every two years to have the devices replaced when the batteries wear down. With the new device, the patient is given a portable charging device. He plugs it in and places a ' 'charging head" against his chest over the place where the pacemaker is implanted. It charges through his skin. A weekly charge of 90 minutes is recommended, but the pacer will operate without recharge for about eight weeks, officials said. It is also smaller and lighter than present models, using a power cell adapted from NASA space programs. Medical Ethics Instruction Urged by Panel of Doctors WASHINGTON (UPI) A human panel of physicians disturbed by recent reports of experimentation and sterilization without informed consent has called for mandatory instruction on medical ethics for all students of the health sciences. "What we need is a massive educational program in all institutions that have to do with the health sciences/' said Dr. Paul H. Andreini, an internal medicine consultant at the Mayo Clinic, Rochester, Minn. "I have been very disturbed over the past five or six years in the apparent lack of interest by many physicians in the area of ethics and by the lack of interest by attorneys in this area," he said at a news seminar on the subject sponsored by the Joseph P. Kennedy Jr. Foundation.. Andreini was one of three awarded anatomy from the University of Colorado in 1956 and an M.D. from Yale in June, said most medical students are not taught about ethical principles or the value of human life. ethics "\T. is in a sense being taught bad ethics because then it's left up to the ore ailin in a physicians recently $18,000 fellowships foundation to study ethics.

"It seems to me that the prevailing idea in a society or in a community is simply a cost benefit type of approach. If it's economically beneficial, then it's good. If it's not economically beneficial, then it's bad." Seminar Proposed Dr. David Allen, now chief resident of the Harvard Psychiatric Service at Boston City Hospital and another winner of a Kennedy fellowship, said he was trained in the United Kingdom, in Scandinavia and worked in the West Indies and in Boston and never received any formal discussion of medical ethics or controversial problems. "I think it should be mandatory that every medical student either yearly or at least some time during his training abuses of medical patients have dramatically underlined the i well organized and contempo- need for more intensive train-:rary seminar or discussion in ing of physicians in ethics and these crucial issues involving morality."
