The pathology of rhinitis is what

Everyone wants to have a healthy nasal cavity to breathe fresh air, but the presence of various nasal diseases so that people's dreams are blocked, rhinitis is such a nasal disease, suffering from rhinitis friends breathing no longer smooth, serious Interfere with the normal life, then how is the rhinitis caused by the following let us look at the etiology of rhinitis it
Pathological etiology of rhinitis:
1. virus infection

Virus infection is the primary cause, or in the virus infection based on secondary bacterial infection. Known to have more than 100 kinds of viruses can cause the disease, the most common is the rhinovirus, followed by influenza and parainfluenza virus, adenovirus, coronavirus, coxsackievirus and mucus and paraneoplastic virus. Virus transmission is mainly through the respiratory inhalation, followed by contaminated body or food into the body.
2. Genetic factors
There is a family history of allergic disease susceptible to the disease. Patient family members have more history of asthma, urticaria or drug allergy. In the past, this patient is an atopic individual, and its ability to produce IgE antibodies in vivo is higher than normal. But in recent years it was found that the incidence of twin and the general population was no significant difference.
3. nasal mucosal susceptibility
The susceptibility is due to the frequent stimulation of antigenic substances, but the degree of susceptibility is the number of mast cells, basophils, and the ability to release chemical mediators in nasal mucosa. It has been confirmed that the number of cells in the nasal mucosa of patients with allergic rhinitis is not only higher than normal, but also has a strong ability to release chemical mediators.
4. Antigenic substances
The antigenic substances that stimulate the body to produce IgE antibodies are called allergens. The allergen material once again into the nasal mucosa, with the corresponding IgE and cause allergic reactions. Cause the disease of the allergen according to its way into the human body is divided into two categories of inhalation and food.
(1) Inhalation allergen ① pollen is not all plant pollen can cause disease, only those pollen large, wide vegetation area, allergenic, and by the wind to spread the pollen is most likely to become allergens The Due to the differences in vegetation varieties, pollen with allergenicity in different areas is also different. ② fungi are widely distributed in nature, mainly in the soil and corrupt organic matter. The hyphae and spores are allergenic, but with strong spores. ③ house dust mite arthropod door spider gang. Adult size is generally 300 ~ 500μm. Mainly parasitic in every corner of the room, which mattresses, pillows, sofa mats and other dust in the most. Mite excrement, eggs, scaling and its broken body, can become allergens. ④ animal dander animal dander is one of the strongest allergens. For susceptible individuals, if long-term contact with the animals concerned, can be sensitized. Even after a small amount of deodorization, but also to stimulate the nose symptoms. ⑤ indoor dust is caused by perennial rhinitis one of the common allergens.
(2) ingestion allergen refers to the digestive tract into the human body caused by nasal symptoms of allergen substances. Its role in the nasal mucosa is very complex, it is still not clear. Milk, eggs, fish and shrimp, meat, fruit, and even some vegetables can become allergens.
The above is listed on the pathological cause of rhinitis, hoping to bring help to all of you friends. We understand the pathophysiology of rhinitis, we should pay attention to the daily life to avoid the emergence of these factors, so that they have a healthy nasal cavity, breathe fresh air, so that our lives better.
