Work For Community Improvement
Does your community provide every opportunity for its citizens to stay healthy? Are there lots of good facilities for medical care, exercise, and healthy food shopping? Are the air and water as clean as they can be? Is the neighborhood safe? Are there opportunities for uninsured people to receive decent care?
If you feel that your community could be a healthier place, get involved! Find other people in your neighborhood or in your faith community who feel the same way, or look for organizations that are working to make the kind of improvements you would like to see. Volunteer your time, or get people together to work for change. Like your own health, your community’s health will improve much faster if you take an active role in shaping it.
Volunteer For Research
If you want to help advance your own health, the health of your children and grandchildren, and the health of the entire world, one way to help is to volunteer for medical research. Hospitals, universities, and research labs are always looking for people to participate in basic medical research and clinical trials. Today, they have a particular interest in studying women and ethnic minorities, because older studies often focused mainly on white men. Usually, each study will be looking for people of a particular age, gender, ethnic background, or medical history. Studies often advertise for volunteers in newspapers,on buses and in subways,or on community bulletin boards.The hospital or medical school in your area may have an office that provides information about volunteer opportunities.
Volunteering for research has many benefits. You can know that you are contributing to the world’s medical knowledge. You will usually receive free medical care as part of the study, and you might be paid for your time. You might find out more about your own health because you participated in the study. If you have a chronic medical condition, you might even discover a new treatment that works for you.
If you do volunteer for a study,you should take the informed consent agreement very seriously. Make sure that you carefully read any documents you have to sign and that you fully understand the time commitment and possible consequences of participating in the study. Some studies involve nothing more than answering a questionnaire or having a few simple tests done. Others involve repeated visits to a research center, spanning months or even years, and complicated medical procedures that may not have all the bugs worked out. Always go into a study with your eyes open to its potential risks and benefits.
Develop An Informed Sense Of Risk
In life, we sometimes take chances that are unnecessary and dangerous. Other times, we worry about things that are really not very likely at all. This is especially true of choices that affect our health and safety. For example, some people are afraid to get a flu shot because they’ve heard that some people have bad side effects. However, the chances of getting the flu if you don’t get a shot are much higher than having any serious reaction to the shot itself.
Other people might be excessively worried about everyday germs— for example, they may use tissues to open doorknobs—but don’t adequately protect themselves against sexually transmitted diseases (STDs) such as HIV, syphilis, and herpes. Still others might be afraid to fly on an airplane, but refuse to wear a seat belt in the car. (You’re much more likely to die in a car crash.) In making choices about your health, it’s important to separate how you feel about the risk from what the risk actually is. Your doctor can help you weigh the risks.
New Books Talk about Diseases And Health
Publishing items: Oxford; New York: Oxford University Press, 2008
Version of: 2nd ed
Collection: medical chart
Description:In this second edition of a text for advanced undergraduates and graduate students, the editors integrate a completely new set of contributions from leading researchers in the field to describe the latest research in evolutionary medicine. The book continues to adopt a broad approach to the subject, drawing on medically relevant research from evolutionary genetics, human behavioral ecology, evolutionary microbiology (especially experimental evolution of virulence and resistance), and the evolution of aging and degenerative disease. The book is intended for a broad audience that includes medical students, graduate students in biological sciences, medical and biological educators, medical and biological researchers, and medical practitioners. It will also interest general readers, and an effort has been made to reduce jargon and introduce technical terms as much as possible. Koella is affiliated with the Department of Biological Sciences at Imperial College London. Stearns is affiliated with the Department of Ecology and Evolutionary Biology at Yale University.
Diagnostic chancre
(A) indispensable pour le diagnostic chancre
De manière générale, le diagnostic chancre montrer particulièrement prudents, parce que cette maladie n’est pas courante, mais si ils ont rencontré les conditions suivantes peuvent faire le diagnostic.
(1) avant le début d’une sale histoire de rapports sexuels.
(2) hommes et des organes génitaux féminins et l’émergence d’un écoulement urétral ulcérations buccales ou plus, le sous-sol mou, la douleur et de tendresse.
(3) unilatérale inguinale Wang Xuan, douleur, ulcères Painong.
(4) la tombée de la nuit d’inspection par vision négative la syphilis.
(5) frottis pour Giemsa tache Cha Budao organes Donovan (trouvé par les Japonais MIYAKAWA un résultat de maladies sexuellement transmissibles de l’lymphatique granulome agents pathogènes).
(6) la syphilis sérum test négatif.
(7) Gram tache, peut être révélé négatif streptocoque, mais peut produire des faux positifs et les conditions sont disponibles pour la culture bactérienne.
(B) le laboratoire de diagnostic chancre
Parce que la maladie est maintenant moins du maladies sexuellement transmissibles, le chancre diagnostic devrait être particulièrement prudent. Le diagnostic de laboratoire nécessaires est la clé de chancre. La méthode la plus simple est la tache Gram frottis. Il ya lieu de subordonner la culture bactérienne et l’examen anatomopathologique.
1, frottis
Matériau de l’ulcère pour le frottis, parce que les bactéries dans les sécrétions Nongxing facile de confondre les résultats, il convient tout d’abord nettoyer les ulcères, frottis disponible Gram tache ou Giemsa tache. Duke Lei du test de Papanicolaou pour les courts (2 μ m) de la ligne parallèle avec le statut de teinture, la tache Gram négatif. S’il ya des symptômes typiques, mais aussi Duke Lei laboratoire bactéries, la maladie peut être diagnostiquée.
2, de la culture
Le moyen est communément utilisé gonocoques sérum fœtal bovin agar-agar, chocolat sang-agar-agar, sera échantillons de la surface du callus ulcères de la peau et les débris enlevés, en utilisant tampons stériles prises sécrétions et des ulcères au bas du matériau de base. Des échantillons vont être inoculées dans la planche, la ligne de séparation. Ajouter à l’assiette cinq pour cent à 10 pour cent de dioxyde de carbone et de l’humidité dans un environnement saturé, 33 ℃ ~ 35 ℃ au moins 48 heures de formation à voir des résultats. Lei duc des petites colonies, telles que des taille, lisse, avec hémisphérique. Mais colonie Changcheng différentes formes, avec une translucide, gris clair et jaune peau, et ainsi de suite. Colony est caractérisée par une étroite, comme contraire à la vaccination en anneau, la quasi-totalité de la colonie à moyen glissement.
La formation à la disposition de la colonie d’essai oxydase, réduction de nitrate d’essai, le coenzyme Ⅰ et hémine, et d’autres tests, selon les besoins à être identifiés; peut également être utilisé catalase, l’indométhacine, l’uréase, l’utilisation de sucre, comme les essais Pour être identifiés. — Identification des bactéries est nécessaire pour le diagnostic de chancre. Certains n’ont pas les conditions de laboratoire, une croissance des bactéries qu’on retrouve que le diagnostic de la maladie, est non scientifique.
3, l’examen anatomopathologique
Chancre patients à réaliser les examens pathologiques contribuer au diagnostic de la maladie. Pathologie montré que trois fourchettes pour le pont supérieur au bas des ulcères, une étroite, visibles leucocytes polynucléaires neutrophiles, de fibrine, les tissus nécrosés et Gram-négatives bacilles, avec une moyenne de large, avec la majorité de l’angiogenèse, les cellules endothéliales vasculaires prolifération, cavité vasculaire atrésie Et la thrombose; plus faible dans le derme profond pour la densité des cellules plasmatiques et l’infiltration de lymphocytes.
