  • Abortion Pill - 1,391 words
    Abortion Pill 1. Problem Statement Approval of the abortion pill RU-486, also recognized as mifepristone, has put abortion back into the spotlight. This has stirred up controversial issues of reproductive rights in America, and a growing concern for the potential impact of RU-486 on the well being of our society's morals and values. 2. Facts and Analysis A Brief History Mifepristone, formerly known as RU-486, provides women with a medical alternative to surgical abortion. Mifepristone is an antiprogesterone drug that blocks receptors of progesterone, a key hormone in the establishment and maintenance of human pregnancy. Mifepristone induces spontaneous abortion when administered in early pre ...

As to banking one's own blood, or autologous donations, the Red Cross permits a few "medically suitable" people, referred by their physician, to store their blood if they are likely to need blood transfusion in upcoming elective surgery. They can bank up to four units of blood, taken in the five weeks before surgery. Finally - it can be categorically stated - IT IS ABSOLU ...

  • Birth Control - 1,146 words
    Birth Control The history of the Pill is a history interwoven with capitalism, exploitation, racism and classism. In that this is a historical look at oral contraception, this section will proceed in chronological order through the development, testing and present day situation of "the Pill." This historical look will also discuss the effects of capitalism, exploitation, racism and classism, with a careful look at how the effects of oral contraception were felt in vastly different ways by white women and black women. Development of the Pill was partly facilitated by Katherine McCormic, multi-million dollar widow and friend of Margaret Sanger, who contributed over three million dollars for sc ...

  • Cancer - 1,605 words
    Cancer Final Draft T. J. Cox The problem is cancer. Cancer is the second leading cause of death in the world and my interest in the subject is simple. My mother is the most resilient person I have ever met. Any time I need any kind of inspiration, I need only to think of her. When she was eighteen she was diagnosed with Hodgkins disease. The doctors gave her a less than thirty percent chance of living. Since then she has had cancer three other times. Breast cancer twice in 85 and 90, and most recently, colon cancer two summers ago. She has had many different treatments including chemo and radiation therapy as well as surgery to remove lumps in both breasts and her colon. What is cancer? Ther ...

  • Chinese Medicine - 1,489 words
    Chinese Medicine Acupuncture, Qigong, and Chinese Medicine Stephen Barrett, M.D. Chinese medicine, often called Oriental medicine or traditional Chinese medicine (TCM), encompasses a vast array of folk medical practices based on mysticism. It holds that the body's vital energy (chi or qi) circulates through 14 channels, called meridians, that have branches connected to bodily organs and functions. Illness is attributed to imbalance or interruption of chi.. Ancient practices such as acupuncture and Qigong are claimed to restore balance. Traditional acupuncture, as now practiced, involves the insertion of stainless steel needles into various body areas. A low-frequency current may be applied t ...

    Creatine If, about 5 years ago, you were to tell an athlete there was a supplement (which was not an anabolic steroid or other bodybuilding drug) that would help bodybuilders and athletes pack on as much as 10 rock-hard pounds of muscular bodyweight (which could lead to better performance for athletes) in less then 2 weeks; increase their bench press by 25 lbs. (which also would help in enhancing performance) in a mere 10 days; "get a pump like you were loaded on Dianabol"(Phillips 48) (a pump that last for hours and hours which helps in muscle development); and, all the while, help you run faster, jump higher, recover from exercise more quickly, they would probably tell you to get lost.

    ... Gibson,1980). A more recent study published in the Lancet compared the effects of a homeopathic preparation of mixed grass pollen with placebo in 144 patients with active hay fever. Patients treated with homeopathic remedies showed a significant reduction in both patient and doctor assessed symptom scores. There was no evidence that placebo effect could fully explain the reduction in symptoms. ( Reilly,1986). As mentioned previously, a review of 107 clinical trials of homeopathic medications published in the British Medical Journal, showed positive results of homeopathy in 81 trials. (Kleijnen,1991) Although there has been research to validate the methodology and the effectiveness of hom ...

  • Legalization Of Marijuana - 612 words
    Legalization Of Marijuana Legalization of Marijuana Legalization of Marijuana has quickly become a controversial issue in America. In the United States, legalization of marijuana for medicinal purposes is spreading to the state level. For example, in November 1996, the people of California and Arizona voted to legalize marijuana for medicinal reasons. As a result of Proposition 215 in California, patients now smoke marijuana provided their physician recommends its usage. A prescription is not required, and marijuana continues to be illegal to prescribe. The Clinton administration responded that it would not recognize these decisions, and would prosecute physicians who recommend or provide ma ...

  • Lung Cancer - 1,671 words
    ... . There are three subtypes within this group. Some types grow more quickly than others. Ask your doctor to explain which of these you have. There are a few other rare types of lung cancer not covered in this document. Staging is the process of finding out how far the cancer has spread. This is very important because your treatment and the outlook for your recovery depend on the stage of your cancer. There are different staging systems for small cell and non-small cell lung cancer. Small cell lung cancer staging For small cell lung cancer a two-stage system is most often used. These are limited stage and extensive stage. Limited stage usually means that the cancer is only in one lung and ...

    ... is trying to modify polypyrrole so that it will dissolve into the body and disappear as the nerve regenerates, like biodegradable sutures used in surgery. D. A recent study performed at Cornell University Medical College has demonstrated that exposure to magnetic fields can result in growth and regeneration of nerves. Dr. Saxena, who was in charge of the research used low-level magnetic fields to trigger growth and regeneration of nerve sections in a culture medium (basically a petri dish). The study also found that those nerves that were not exposed to the magnetic fields experienced nerve degeneration. 1. Dr. Saxena said "At the end of the year, we found that included in the new growth ...

  • Ovarian Cancer - 2,095 words
    ... of segments of chromosomes (particularly 3p and 6q) in some tumors is consistent with a role for loss of tumor suppressor genes. Recently, a genetic linkage study of familial breast/ovary cancer suggested linkage of disease susceptibility with the RH blood group locus on chromosome 1p. Allele loss involving chromosomes 3p and 6q as well as chromosomes 11p, 13q, and 17 have been frequently observed in ovarian cancers. Besides allele loss, point mutations have been identified in the tumor suppressor gene p53 located on chromosome17p13. Deletions of chromosome 17q have been reported in sporadic ovarian tumors suggesting a general involvement of this region in ovarian tumor biology. Allelic ...

  • Parasitic Wasps - 2,778 words
    Parasitic Wasps Malaria is one of the most prevalent and dangerous diseases known to man. It has existed for centuries and affects a myriad of people in the tropical region. Even today, with our newly discovered treatments for many of the tropical diseases, over 10% of the people that are infected with malaria each year and do not receive proper treatment die. In Africa alone, over 1 million children die each year because of malaria and new cases are reported frequently. Malaria is very dangerous and harmful to man. However, the protozoan that causes malaria has existed since man came into being. Fossils of mosquitoes that are 30 million years old contain the vector for malaria. After writte ...

Sidney Wolfe, director of the Public Citizen Health Research Group, a Washington based consumer advocacy organization, compares Prozac to Valium, the popular tranquilizer that was on the market for more than 10 years before doctors discovered its highly addictive properties during the mid-1970s. ⌠Prozac has become the Valium of the 1990s,■ declares Wolfe (Nichols, 4) Finally, one of the weaker arguments against Prozac is t ...

  • Sensitive Chromosome Probes Recently Discovered By A University Of Toronto Geneticist Will Make It Easier To Detect Certain T - 714 words
    Sensitive chromosome probes recently discovered by a University of Toronto geneticist will make it easier to detect certain types of genetic and prenatal diseases, as well as being used to determine paternity and provide forensic evidence in criminal cases. Probes are short pieces of DNA which bind to, and actually pinpoint, particular sites on a chromosome. Because these new probes are actually repeated hundreds or thousands of time at a particular site, they are much more sensitive than previously available ones. Of the 23 pairs of human chromosomes, Dr. F.H. Willard has discovered repeated probes or markers for six plus the gender determining X and Y chromosomes. "What we're trying to dec ...

  • Skin Cancer - 1,649 words
    "Skin Cancer" ------------------ Gone are the days when people sent children outside to play to get a little color in their cheeks. They know too much about the dangers of unprotected sun exposure and the threat of skin cancer. Or do they? Despite the fact that 58% of parents remembered hearing about the importance of protecting their children from the sun, children are still playing in the sun without sunscreen or protective clothing (3., p 1). Sunburn is the most preventable risk factor of skin cancer. Skin type and family history cannot be changed. Protection from the sun and education of the potential hazards of the sun need serious attention. The American Cancer Society estimates that o ...

  • Vaccine Could Protect Against Stroke And Epilepsy - 1,277 words
    Vaccine Could Protect Against Stroke And Epilepsy Vaccine Could Protect Against Stroke And Epilepsy Damage February 25, 2000 A new oral vaccine has offered new hope because of its effectiveness in protecting laboratory rats against brain damage from epilepsy and stroke, and might one day be used to help humans with the same conditions. The vaccine blocks a protein in the brain called NMDA, but does so only when epilepsy or stroke occur. The vaccine is released in the brain as needed and is protected from any side effects. During and colleagues immunized another group of rats and after five months induced stroke in them by blocking an artery in the brain. The rats still experienced strokes, b ...

  • Why I Got Into Medicine - 625 words
    Why I Got Into Medicine I grew up in a research and development campus where my father is a scientist. Research and curiosity were constantly encouraged and this prompted me to take up medicine as a career, a field that offers tremendous prospects for research and discoveries. Throughout medical school I tried to be involved in research and attempts at trying out new ideas, be it in the lab or working with human subjects. I carried this through my residency and now my fellowship. The idea of studying a topic or issue that has so far not been treaded upon seems to be extremely exciting and challenging. I have always wanted to be a scientist and contribute something to the human cause and what ...
