your invisible enemy

One of the most mysterious diseases, which certainly fit the word "allergic" is hay fever.

"Hay fever or pollen allergy, also known as hay fever (pollen - pollen) - Allergic disease which is caused by an inadequate immune response to pollen of various plants. Pollen from the surrounding air settles on the mucous membranes of the nose, eyes and mouth, enters the bronchial tubes, in contact with the skin, and sensitive to her people, symptoms of allergies.

Of the several thousand common on the globe plant species only about 50 produce pollen that can cause allergic disease.

Those who suffer allergy to pollen, may look worst enemy in the face, so these plants, which do not allow you to live peacefully. Swiss scientist Martin Oeggerli used scanning electron microscope to take photographs of pollen grains in his basement.

Few theory of immunoglobulins and histamine

For some people, often starting from early childhood, spring and summer flowering periods of Plants turn into torturous days, weeks or even months. It happens to those who have in the body, there were changes of immunity, which, at penetration pollen particles in the mucous membranes of the eyes, nose, bronchial tubes, creating an opportunity to respond to the intake in the pollen swelling of mucous membranes, their redness, increased local temperature, that is, phenomena that are known to all as inflammation.

Such events occur due to the fact that an organism such people in more than all the others, produced a special protein - immunoglobulin E, which are attached to so-called fat cells, mostly located precisely in the mucous membranes of various organs (conjunctiva, nasal mucosa, bronchi). And in pollen are Other - vegetable proteins, which can combine with immunoglobulin E, and when it occurs on the surface of mast cells triggers a signal that that mast cells have to throw them stored in a substance called histamine. This is the histamine effect on smooth muscles of internal organs and the walls of blood vessels and causes it to decline or, as doctors say - spasm. Because of this, blood vessels are not such as in healthy people. They become more "weak" are beginning to pass into the surrounding tissue fluid from the blood, resulting in increased discharge from the nose and bronchi mucus and tears from his eyes, there is a swelling of surrounding tissues. In these places and then going to a special protective cells available to all people and are able to move in the damaged tissue. This process is called inflammation. Only this allergic inflammation, but it can become infectious if the focus of an allergic inflammation activated by any bacteria or viruses, many of which are almost always present in the organism and the environment.
