Study Notes
-
Viruses cause cell death through multiplication inside cells or by inhibiting their function, leading to cell death or cell rupture.
-
Bacteria produce specific toxins that can cause a hypersensitivity reaction, an inappropriate immune response that damages tissues.
-
Physical or chemical agents, such as irritants or corrosive chemicals, can cause tissue damage and inflammation through direct contact or radiation.
-
Tissue necrosis, or cell death due to lack of oxygen or nutrients, leads to an acute inflammatory response.
-
Inflammation can have both local and systemic effects, including fever, malaise, and leukocytosis (an increase in circulating white blood cells).
-
Fever is a common response to inflammation, and its function is to improve the efficiency of leukocyte killing and impair the replication of some invading organisms.
-
Inflammation can occur as a result of various causes, including viral and bacterial infections, physical trauma, and chemical or radiation exposure.
-
Tissue damage from inflammation can lead to further complications, such as chronic inflammation, scarring, and tissue fibrosis.
-
Inflammation can also have a systemic impact on the body, leading to symptoms such as fever, malaise, and fatigue, as well as potential long-term health consequences.
-
Acute inflammation is characterized by vascular changes, including vasodilation and increased vascular permeability, leading to edema and white blood cell recruitment.
-
The stimuli for acute inflammation include infections, tissue damage, immune reactions, and chemical mediators.
-
Infections, such as bacterial, viral, fungal, parasitic, and microbial toxins, can cause tissue necrosis and inflammation.
-
Immune reactions, including hypersensitivity reactions, can also trigger acute inflammation.
-
Chemical mediators, such as histamine and cytokines, can cause vascular leakage and further contribute to inflammation.
-
Physical agents, like ischemia, trauma, and thermal injury, can cause tissue damage and vascular leakage.
-
Foreign bodies, like splinters, dirt, and sutures, can also trigger an inflammatory response.
-
In chronic inflammation, the inflammatory response persists for a long duration and results in tissue destruction, repair, and fibrosis.
-
Chronic inflammation can be caused by persistent injury or infection, prolonged exposure to toxins, and autoimmune diseases.
-
Chronic inflammation is a common component in many diseases, including ulcers, tuberculosis, pulmonary silicosis, and autoimmune diseases like rheumatoid arthritis, lupus erythematosus, and multiple sclerosis.
-
Chronic inflammation tends to occur under certain conditions, including persistent organisms, repeated bouts of acute inflammation, and prolonged exposure to toxins.
