Study Notes
Chronic Inflammation
- Defined as a prolonged inflammatory response characterized by simultaneous tissue destruction and healing.
- Can lead to various diseases and conditions if unresolved.
Types of Chronic Inflammation
- Infective Chronic Inflammation: Resulting from persistent infections, such as those caused by bacteria or viruses.
- Non-Infective Chronic Inflammation: Triggered by factors like autoimmune diseases or chronic irritants.
Granulomas
- Caseating Granuloma: Activated macrophages are the primary reactive cells, often seen in infections like tuberculosis.
- Infective Granuloma Example: Tuberculosis is a classic example related to caseating granulomas.
Patterns of Chronic Inflammation
- Distinct pattern includes granulomatous inflammation, where small granules fuse into a tumor-like mass, termed a granuloma.
Non-Infective Granuloma Example
- Sarcoidosis serves as a prominent example of non-infective granulomas, characterized by the collection of immune cells.
Wound Healing
- Secondary Intention Healing: Occurs when wound edges cannot be apposed, usually resulting in more extensive scarring.
- Replacement of damaged tissue by granulation tissue evolving into fibrous tissue is termed organization.
- Factors like infection or poor nutrition can delay wound healing and increase granulation tissue formation.
Regeneration and Cell Division
- Best example of healing by regeneration in humans is liver regeneration after partial hepatectomy.
- Stem cells are responsible for continuous cell division, replacing damaged cells throughout life.
Types of Inflammation and Repair
- Organization: Healing process in inflammation characterized by the formation of granulation tissue during chronic inflammation.
- Tissue Repair: Involves replacement of injured cells by the same type, known as regeneration.
