Lecture 4 - Chronic Inflammation Flashcards
Clinical presentations of acute inflammation (local effects)?
redness, swelling, heat, pain, loss of function
Clinical presentations of inflammation (systemic effects)?
fever, leukocytosis, acute phase proteins from liver, increased glucocorticoid steroid hormones
Inappropriate inflammatory responses?
Rheumoid artheritis, atherosclerosis, hypersensitivity to toxins, hyper-immune reactions
Macrophage characteristics?
Monocytes that enter the injured tissue, greater phagocytic potential than neutrophils, interface closely w lymphocytes
Granuloma?
specific pattern of chronic inflammation seen in diseases just such as tuberculosis
Granuloma formation?
core of necrosis, aggregations of macrophages turn into epithelium-like cells (epithelioid macrophages), collar of lymphocytes surround, macrophages fuse together to make giant cells
Directions of injured tissue after inflammation?
resolution (tissue to normal); repaor (organisation into granulation tissue -> non-functional fibrous scar); regeneration (tissue structure and function rebuilt to some previous function)
