What is radiation sickness?(2)
The degree of illness (acute radiation sickness) depends on the dose and the rate of exposure. Exposure from x-rays or gamma rays is measured in units of roentgens. For example:
1. Total body exposure of 100 roentgens causes radiation sickness.
2. Total body exposure of 400 roentgens causes radiation sickness and death in half the individuals.
3. 100,000 rads causes almost immediate unconsciousness and death within an hour
The severity of symptoms and illness depends on the type and amount of radiation, the duration of the exposure, and the body areas exposed. Symptoms of radiation sickness usually do not occur immediately following exposure.
Because it is difficult to determine the amount of radiation exposure from accidents, the best indications of the severity of the exposure are: the length of time between the exposure and the onset of symptoms, the severity of symptoms, and severity of changes in white blood cells.
Children who receive radiation treatments or who are accidentally exposed to radiation will be treated based on their symptoms and their blood cell counts. Frequent blood studies are necessary and require a small puncture through the skin into a vein to obtain blood samples.
Then the causes include: Accidental exposure to high doses of radiation, such as in certain occupations Exposure to excessive radiation for medical treatments (may include excessively high doses, excessive time of exposure, or excessive body areas exposed)

What is radiation sickness?(1)

Radiation sickness it is also be called  radiation poisoning,   is illness and symptoms resulting from excessive exposure to radiation. Exposure may be accidental or intentional
So far, There are two basic types of radiation: ionizing and nonionizing.
Nonionizing radiation comes in the form of light, radio waves, microwaves and radar. This kind of radiation usually does not cause tissue damage.
Ionizing radiation is radiation that produces immediate chemical effects on human tissue. X-rays, gamma rays, and particle bombardment (neutron beam, electron beam, protons, mesons, and others) give off ionizing radiation. This type of radiation can be used for medical testing and treatment, industrial and manufacturing purposes, weapons and weapons development, and more.
Radiation sickness results when humans (or other animals) are exposed to very large doses of ionizing radiation. Radiation exposure can occur as a single large exposure (acute), or a series of small exposures spread over time (chronic).
Radiation sickness is generally associated with acute exposure and has a characteristic set of symptoms that appear in an orderly fashion. Chronic exposure is usually associated with delayed medical problems such as cancer and premature aging, which may happen over a long period of time.
And we will introduce more knowledge about the degree of this sickness and the cause of it in next article

High Blood Pressure Prevention

            Since there are so many people have high blood pressure, which is a major risk factor for heart and kidney diseases, stroke, and heart failure. High blood pressure is especially dangerous because it often gives no warning signs or symptoms. Fortunately, you can find out if you have high blood pressure by having your blood pressure checked regularly. If it is high, you can take steps to lower it. Just as important, if your blood pressure is normal, you can learn how to keep it from becoming high.
Then you can prevent high blood pressure by:
Maintaining a healthy weight:  Being overweight can make you two to six times more likely to develop high blood pressure than if you are at your desirable weight. Even small amounts of weight loss can make a big difference in helping to prevent and treat high blood pressure.
Getting regular exercise:  People who are physically active have a lower risk of getting high blood pressure -- 20%-50% lower -- than people who are not active. You don't have to be a marathon runner to benefit from physical activity. Even light activities, if done daily, can help lower your risk.
Reducing salt intake: Often, when people with high blood pressure cut back on salt, their blood pressure falls. Cutting back on salt also prevents blood pressure from rising.
Drinking alcohol in moderation, if at all: Drinking too much alcohol can raise your blood pressure. So to help prevent high blood pressure, if you drink alcohol, limit how much you drink to no more than two drinks a day. The "Dietary Guidelines for Americans" recommend that for overall health, women should limit their alcohol to no more than one drink a day.
Reduce Stress: Stress can make blood pressure go up and over time may contribute to the cause of high blood pressure. There are many steps you can take to reduce your stress. The article on easing stress will get you started.
After doing these steps, you will be much more healthy. Then you can take a blood test on hematology analyzer for blood cells , or other blood test device to know if you have high pressure now .Until you have healthy body , then you can get a happy life .

X-Ray Exams of the Digestive Tract(3)

Then we continue to introduce some knowledge that is necessary to know when you have got an exam by x ray machine.
Firstly , you may ask, are there GI test safe?
There is virtually no risk with the upper and lower GI tests, unless they are repeated several times within a few months' time, when radiation exposure can become a risk. Although radiation exposure is minimal, it is greater than for standard still X-rays. Steps will be taken during the test to minimize radiation exposure.
Other risks include: 1.Infection (very low risk with both the upper and lower GI tests). 2. Tearing the intestinal wall during a lower GI test. Should this occur, surgery may be necessary. This is a very rare complication.
      And then who should not receive GI Tests?
      If you have an existing blockage or tear in the intestinal wall, the upper and lower GI tests should not be performed.If you are pregnant or think you might be pregnant, you should not have these tests unless absolutely medically necessary. Talk to your doctor about other tests that can be more safely performed to diagnose your problem during pregnancy.

X-Ray Exams of the Digestive Tract(2)

Today , we will continue to introduce lower GI tests.
Lower GI tests or barium enemas are used to examine the large intestine and the rectum. For this test, barium or an iodine-containing liquid is introduced gradually into the colon through a tube inserted into the rectum. As the barium passes through the lower intestines, it fills the colon, allowing the radiologist to see growths or polyps and areas that are narrowed. The fluoroscope is held over the part of the body being examined and transmits continuous images to the video monitor.
This lower GI testing is used to detect:  Colon polyps ,Tumors ,Diverticular disease ,Gastroenteritis ,Strictures or sites of narrowing and obstruction ,Ulcerative colitis or Crohn's disease and other causes of abdominal pain or blood, mucus, or pus in the stool
With the barium or contrast enema, the colon is filled with a contrast material containing barium or iodine-containing contrast (a liquid that lights up on X-ray) by running it through a tube inserted into the rectum. The barium blocks X-rays; therefore the colon, when filled with the agent, shows up clearly on the X-ray picture.
The air contrast study is slightly different. The colon is first filled with some barium, and then the colon is filled with air. This technique provides a more detailed picture of the lining of the colon, improving the procedure's ability to detect small polyps or inflammation.

Joint x-ray

Joint x-ray is a new name of x ray in medical zone. But is not a new technology for x ray machine (whether from mobile x ray machine or stationary x ray machine)
The definition of this test is an x-ray of a knee, shoulder, hip, wrist, ankle, or other joint.
The test is performed in a hospital radiology department or in the health care provider's office by an x-ray technician. You will position the joint to be x-rayed on the table, pictures are taken, and the joint is repositioned, if necessary, for different views.
Inform the health care provider if you are pregnant. Remove all jewelry. The x-ray is not uncomfortable, except possibly from positioning the area being x-rayed. The x-ray is used to detect fractures, tumors, or degenerative conditions of the joint. The x-ray may reveal arthritis, fractures, bone tumors, degenerative bone conditions, and osteomyelitis (inflammation of the bone caused by an infection).
There is low radiation exposure. X-rays are monitored and regulated to provide the smallest amount of radiation exposure needed to produce the image. Most experts feel that the risk is low compared with the benefits. Pregnant women and children are more sensitive to the risks of the x-ray.

Medical x ray ----Great Discovery in World Medical

One of medicine's most remarkable achievements is the use of X-rays to see inside the body without having a surgeon wield a scalpel. The suitable medical machine are mobile x ray machine , c arm x ray machine , digital x ray machine and so on .
X-rays are used for much more than identifying injuries from accidents. They are used to screen for, diagnose, and treat various medical conditions. X-rays can be used on just about any part of the body—from the head down to the toes—to identify health problems ranging from a broken bone to pneumonia, heart disease, intestinal blockages, and kidney stones. And X-rays cannot only find cancerous tumors, but can often destroy them.
Along with their tremendous value, medical X-rays have a drawback: they expose people to radiation. FDA regulates radiation-emitting products including X-ray machines. But everyone has a critical role in reducing radiation while still getting the maximum benefit from X-ray exams.
X-rays are a form of electromagnetic radiation that can penetrate clothing, body tissue, and internal organs. An X-ray machine sends this radiation through the body. Some of the radiation emerges on the other side of the body, where it exposes film or is absorbed by a digital detector to create an image. And some of it is absorbed in body tissues. It is the radiation absorbed by the body that contributes to the "radiation dose" a patient gets.
    Nowadays, there are more and more medical manufacturer that they spare no effort to improve x ray machine , and reduce x ray dose on patients as much as they can. So don’t worried about the radiation from x ray, it won’t do much harm to our body.

For this test, barium or an iodine-containing liquid is introduced gradually into the colon through a tube inserted into the rectum. As the barium passes through the lower intestines, it fills the colon, allowing the radiologist to see growths or polyps and areas that are narrowed. The fluoroscope is held over the part of the body being examined and transmits continuous images to the video monitor.
This lower GI testing is used to detect:  Colon polyps ,Tumors ,Diverticular disease ,Gastroenteritis ,Strictures or sites of narrowing and obstruction ,Ulcerative colitis or Crohn's disease and other causes of abdominal pain or blood, mucus, or pus in the stool
With the barium or contrast enema, the colon is filled with a contrast material containing barium or iodine-containing contrast (a liquid that lights up on X-ray) by running it through a tube inserted into the rectum. The barium blocks X-rays; therefore the colon, when filled with the agent, shows up clearly on the X-ray picture.
The air contrast study is slightly different. The colon is first filled with some barium, and then the colon is filled with air. This technique provides a more detailed picture of the lining of the colon, improving the procedure's ability to detect small polyps or inflammation.

What is the live blood test analyzer?(1)

Live blood analysis – also known as live blood cell analysis, nutritional microscopy or sometimes darkfield microscopy biological terrain assessment – is fundamentally the analysis of living blood under an extremely powerful microscope connected to a camera. This diagnosis process is operated on the hematology analyzer.
The condition and quality of your red blood cells have a direct impact on your present and future health, with stress and disease appearing in the blood years before they manifest in the body. So what do your blood cells look like?
Live blood testing enables us to see your blood exactly as it behaves inside your body, giving a clear picture of your health at a cellular level. We are not looking for patterns that lead to a ‘diagnosis’ in any shape or form, but are merely looking for imbalances in the pH levels in your blood.
Then what is different form regular test blood test ? That is to say that what advantage do the live blood test have to the regular blood test ? We will introduce the answer in another news .

X-Ray Exams of the Digestive Tract(1)

There are several commonly performed X-ray tests that allow your doctor to examine your digestive tract from the esophagus to the rectum.
These tests utilize barium or an iodine-containing agent that allows visualization of the digestive tract and a form of X-ray machine called fluoroscopy. Fluoroscopy allows part of the body to be studied in motion and recorded on a video monitor.
Fluoroscopic examinations of your GI tract may be performed in a doctor's office, a commercial X-ray machine, or a hospital. These tests are usually called either an "upper GI" or a barium or contrast enema or a "lower GI", depending on the organs to be studied.
Today, we will mainly introduce Upper GI tests.
Upper GI tests use X-rays to examine the esophagus, stomach, and first part of the small intestine (the duodenum). You could see some articles about the digestive system to learn more about these organs.
For these tests, a person is required to drink barium. As the barium passes through the digestive tract, it fills and coats the esophagus, stomach, and first part of the small intestine making them more visible with X-ray. Then a fluoroscope machine is held over the part of the body being examined and transmits continuous images to a video monitor.

What is the live blood test analyzer?(2)


In order to best understand the difference and the benefits of this particular test it is necessary to consider the conventional blood test that is given at the doctor’s surgery or hospital, known as a Complete Blood Count (CBC). Almost every person has experienced this particular test which involves inserting a needle into the patient’s arm and extracting a syringe full of blood, which can be a very painful ordeal for some people. The blood sample is then sent to a laboratory to be examined by a haematologist and it can take up to two weeks to receive the results. 
However, the major problem with this test is that half an hour after the blood cells are extracted from the human body they die so the haematologist is merely counting dead blood cells. The blood is also changed through the addition of stains and dyes in order to facilitate the analysis. The results take the form of a quantitative analysis of the blood, that is to say how many dead red blood cells, how many dead white blood cells, what number is the cholesterol level etc.
Above these , we can know , in some way , live blood test have a big advantage when we do some blood test for sick diagnosis by hematology analyzer or other medical analyzer. The live blood can tell us more information better then regular blood test.

Does x ray machine can diagnose the SARS correctly ?

There occurs SARS in 2003, and there are so many people seek to medical solution. And doctor will check it under x ray in wards by mobile x ray machine. But in fact it is a wrong way to diagnosis by mobile x ray machine  for SARS only .
Common symptoms are flu-like and include fever, chills, muscle aches, coughing and headaches. Your doctor will likely listen to your breathing through a stethoscope. If you have SARS, your doctor will hear abnormal lung sounds, and he or she will subsequently order a chest X-ray to confirm the presence of pneumonia or respiratory distress syndrome.
SARS-infected lungs typically present with small or large patchy shadows in both lungs on a chest X-ray. In fact, one research study found that 31 of 52 clinical SARS cases showed this pattern. Another 18 clinical SARS cases had small or large patchy shadows in one lung or a segment of lung. The researchers concluded that a chest X-ray is a sensitive and specific method for SARS testing and diagnosis. A person infected with SARS should have a chest X-ray every one to three days to monitor progress or decline.
A chest X-ray alone cannot reliably diagnose SARS; your doctor will probably do a thorough medical history, including a review of your symptoms and any other pre-existing medical conditions. Your doctor may order blood tests by hematology analyzer  that assess blood clotting; ALT and CPK levels, which tend to be high in people with SARS; and potassium and sodium levels, which tend to be low. Your doctor will also likely assess your white blood cell count, your lymphocyte count, and your platelet count, all of which tend to be low if you have SARS. Finally, a specific SARS test, called the PCR test, determines if you have SARS antibodies in your system.

Two Side of X Ray: Harmful and Helpful

As we all know , x-rays for what they are: a type of electromagnetic energy. These rays have short wavelengths, allowing them to carry a lot of energy. So when we get the benefit from it , we also must realize the radiation of  mobile x ray , it can do harm for human body.
Then we've learned that medical X-rays give doctors a unique glimpse into the flesh and bone beneath your skin. It gives doctor and patiently a big favor in operation or daily diagnosis.  But how else are they used?
Today x ray is also used in airport or astronomy. In recent years, the U.S. Transportation Security Administration has used x-ray body scanners to detect weapons and other potentially dangerous objects that can't be picked up by metal detectors. This certainly beefs up security for passengers before boarding an airplane, but it also exposes them to x-ray radiation. And in astronomy , Many events in space, ranging from black holes to comets and stars, give off unique radiation signatures. Although we generally clump all X-rays together, the ones coming from space are a bit different. They're created from natural phenomena in the universe that give off immense amounts of energy (and heat).
To measure x-ray radiation, or the energy from particles in space, scientists collect information using satellites outside Earth's atmosphere. Such x-rays give us clues to the origins of the universe and contribute to our perceptions of auroras that routinely line the night sky.
As we'll discuss, X-rays emit a type of radiation that can be harmful to humans if the intensity is too high or the exposure is too frequent. So we must take attention to the x ray ,and protect ourselves from it necessarily .
