Objective:
To explore the expression of Eotaxin and the effect of histamine in allergic rhinitis model (AR), and aim to explore the pathogenesis of AR.
Method:
The AR models were established by application of ovum albumin in rats. The expression of Eotaxin in nasal mucosa, serum and nasal cavity lavage fluid, were observed before and after treatment of histamine or its antagonist by immunochemistry, RT-PCR and ELISA technique.
Result:
The expression of Eotaxin in nasal lavage fluid and nasal mucosa increased after treatment of histamine (P < 0.05). Contrarily, the expression of Eotaxin in nasal lavage fluid, nasal mucosa and serum decreased after treatment of the antagonist of histamine.
Conclusion:
Both histamine and its receptor can involve in the pathogenesis of AR by affecting the expression of Eotaxin.

Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antibodies consist of four polypeptide chains: two identical heavy...
Allergic Reactions: Anaphylaxis
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
