Summary
Chronic hypertrophic rhinitis affects nasal conchae structures but spares regenerative potential. Local immune defenses, including IgA synthesis and immune cells, remain functional, suggesting caution during surgery.
Area of Science:
- Immunology
- Rhinology
- Histopathology
Background:
- Chronic hypertrophic rhinitis is characterized by nasal mucosa inflammation.
- Understanding the regenerative capacity and immune status is crucial for treatment.
Purpose of the Study:
- To investigate the histological and immunological status of nasal mucosa in chronic hypertrophic rhinitis.
- To assess the regenerative potential and local immune mechanisms.
Main Methods:
- Histological and immunohistochemical analysis of inferior nasal conchae mucosal tissue.
- Evaluation of epithelial structures, vascular endothelium, glands, and immune cell populations (CD45 RO(+), CD20(+), CD68(+)).
Main Results:
- Pathological changes observed in epithelium, lamina propria, and cavernous sinuses.
- Preserved epithelial proliferative activity, normal vascular endothelium and basement membranes.
- Persistent IgA synthesis and retained functional activity of T-lymphocytes, B-lymphocytes, and macrophages.
Conclusions:
- Nasal mucosa exhibits significant regenerative potential in chronic hypertrophic rhinitis.
- Local protective mechanisms, including cellular and humoral immunity, remain largely intact.
- Surgical interventions require careful consideration due to preserved mucosal integrity and immune function.

01:24Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
01:23Chronic Pharyngitis
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

01:28Asthma I: Introduction
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

01:26Asthma-II: Pathophysiology and Classification
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
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:
