Disease Arthritis

Wednesday, March 25th, 2009

The term “arthritis” is used to describe a medical condition in which the bones and joints are inflamed. Inflammation of the joints that causes pain is commonly known as arthritis. Arthritis can be of different types. The most common types are rheumatoid arthritis and osteoarthritis. The symptoms of rheumatoid arthritis are severe. If a person is affected by this disease first destroys the body’s immune system and this in turn causes severe pain in joints. If not treat carefully, can lead to a complicated situation. A patient can deal with extreme difficulty, while moving from one place to another. Osteoarthritis is the most common type of arthritis. However, symptoms of this disease are less severe than rheumatoid arthritis. This type of arthritis can be treated for arthritis pharmaceuticals available in the market.

The causes of arthritis

Although the exact cause of arthritis has not been noted, however, some doctors say that arthritis can be caused by metabolic disorders, infections, hereditary factors, etc. Sometimes the injuries, an overactive immune system can also cause this disease. In fact, the cause of arthritis varies greatly from person to person.

The symptoms of arthritis

The symptoms of different types of arthritis are more or less similar. Common symptoms of arthritis are pain in the joint, swelling, redness, warmth, stiffness in the joint etc. Some people still suffer from tenderness. Apart from these patients may have to deal with some other symptoms such as fatigue, weight loss, swollen glands, fever, etc. In some cases, might face a very difficult patient to walk.

Both men and women equally affected by this disease. Although this disease is common in adults, in some cases, young people are also affected by it. A statistical report shows that people with this disease are women.

Role of Microbes in The Gastrointestinal Tract

Friday, March 20th, 2009

The microbes present in the gastrointestinal tract have the potential to act as a positive, negative or neutral. Due to unfavorable conditions, microbes are not very frequent in the stomach or upper small intestine. However, towards the lower small intestine, they begin to achieve higher populations.

In view of the high number of microbes in the intestinal area, what are its effects?

It is known that microbes in the large intestine complete the digestion process in any component of the food is not digested in the small intestine, as in people with lactose intolerance to lactose or fiber resistant to enzymes that are found in the small intestine. There is evidence of non-digestive microbial activities as well. Certain intestinal microbes are known produce vitamins. Also, in studies with laboratory animals free of specific microbes, the evidence is strong that without normal microbial populations, the immune system malfunctions, and resistance to pathogenic bacteria is reduced greatly. Other evidence suggests that intestinal microbes might act (capable of inducing genetic mutation) composite pre-carcinogens or mutagens. Depending on the specific microbe, mutagenic or carcinogenic activity may be increased or decreased.

Clearly there are advantages to skew the balance toward the beneficial bacteria. Lactobacilli and bifidobacteria are normal inhabitants of the gut healthy. While not the dominant genre in the small intestine or large adults (bifidobacteria is usually the dominant flora of children raised to the chest) are not pathogenic and their presence correlates with a healthy intestinal flora. The metabolic end products of their growth are organic acids (lactic and acetic acids) which tend to lower the pH of intestinal contents, creating conditions less desirable for harmful bacteria.

The gastrointestinal tract also serves as a bridge between “the body” and “outside the body.” Through this interface, microbes and foreign antigens pass through the gastrointestinal area and interact with the major components of the immune system. This interaction serves to stimulate or develop the immune system for optimal functioning. The normal microbial inhabitants of the gastrointestinal tract also reinforce the barrier function of the intestinal lining, decreasing the passage of bacteria or antigens from the intestine into the blood. This function has been suggested that decreases infections and possibly allergic reactions to food antigens.
