华裔女子涉用放射性金属毒杀丈夫被控

你的医学或物理化学常识都有误！又让人笑了！ “铊”恐怕不属于放射性物质，以讹传讹就不好了！

回复 *火眼金睛*：你不但医学知识贫乏有误，而且对一般的文字识别理解也有问题。更重要的是为了达到你自己不可告人的目的，善于断章取义。 你回的那一帖明明写的是：据香港《星岛日报》报道。你为什么要删除？目的何在？道德何在？ 第八帖才真正是我的：铊中毒是机体摄入含铊化合物后产生的中毒反应。铊对哺乳动物的毒性高于铅、汞等金属元素，与砷相当，其对成人的最小致死剂量为12mg/kg体重，对儿童为8.8～15mg/kg体重。中毒后表现症状为下肢麻木或疼痛、腰痛、脱发、头痛、精神不安、肌肉痛、手足颤动、走路不稳等。 请看清楚了再发言，要有针对性，不要断章取义，更不要再“出洋相”了。

回复 *火眼金睛*：你一个自称具有医学硕士学位，并在美国开业的人，居然弄出如此之大的洋相。你已经不是第一次出医学之丑了。使人不得不怀疑你的情况的真实性。 None of the thallium ordinarily found in nature is radioactive. Like all elements, there are synthetic radioactive isotopes of thallium. Thallium Stress Test ( basic knowledge for medical professionals) This is a type of nuclear scanning test or myocardial perfusion imaging test. It shows how well blood flows to the heart muscle. It's usually done along with an exercise stress test on a treadmill or bicycle.The thallium stress test is useful to determine:Extent of a coronary artery blockagePrognosis of patients who've suffered a heart attackEffectiveness of cardiac procedures done to improve circulation in coronary arteriesCause(s) of chest painLevel of exercise that a patient can safely performWhen the patient reaches his or her maximum level of exercise, a small amount of a radioactive substance called thallium is injected into the bloodstream. Then the patient lies down on a special table under a camera ("gamma camera") that can see the thallium and make pictures. The thallium mixes with the blood in the bloodstream and heart's arteries and enters heart muscle cells. If a part of the heart muscle doesn't receive a normal blood supply, less than a normal amount of thallium will be in those heart muscle cells.The first pictures are made shortly after the exercise test and show blood flow to the heart during exercise. The heart is "stressed" during the exercise test — thus the name "stress test." The patient then lies quietly for 2-3 hours and another series of pictures is made. These show blood flow to the heart muscle during rest.What does the thallium stress test show?If the test is normal during both exercise and rest, then blood flow through the coronary arteries is normal. The coronary arteries supply blood to the heart muscle. If the test shows that perfusion (blood flow) is normal during rest but not during exercise (a perfusion defect), then the heart isn't getting enough blood when it must work harder than normal. This may be due to a blockage in one or more coronary arteries. If the test is abnormal during both exercise and rest, there's limited blood flow to that part of the heart at all times. If no thallium is seen in some part of the heart muscle, the cells in this part of the heart are dead from a prior heart attack. (They have become scar tissue.)
