病理绪论(英文版)课件

病理绪论(英文版)课件
Oxygen deprivation ( hypoxia, ischemia) Nutritional imbalances Physical agents Chemical agents and drugs Infectious agents Immunologic reactions Genetic derangements
1. Etiology
1. Etiology
Knowledge of etiology remains the backbone:
Disease diagnoses Understanding the nature of diseases Treatment of diseases.
While much still needs to be uncovered to link abnormal genes and the expression of disease, gone are the time when the mechanisms of most diseases were unknown? or obscure? or mysterious?
Depleted glycogen. Reduced intracellular pH: Lactic acid and
inorganic phosphate. Mitochondrial damage Clumping of nuclear chromatin.
Four biochemical themes
in cell and tissues. FUNCTIONAL CONSEQUENCES:
Functional consequences of the morphologic changes, as observed clinically (clinico-pathological correlation, CPC ).

病理学英文课件：Acute and Chronic inflammation

病理学英文课件：Acute and Chronic inflammation
Acute inflammation is the immediate and early response to injury designed to deliver fluid and leukocytes to sites of injury Phases of acute inflammation Initiation Amplification Termination Core events in acute inflammation Vascular reaction Fluid and cellular exudation
Overview of Inflammation
Inflammation is divided into acute and chronic patterns
Acute inflammation is rapid in onset (seconds or minutes) and is of relatively short duration, lasting for minutes, several hours, or a few days; its main characteristics are the exudation of fluid and plasma proteins (edema) and the emigration of leukocytes, predominantly neutrophils
-- pain, edema, cell injury
Erysipelas of the face Spreading acute inflammation of the dermis and subcutis due to infection by streptococcus pyogenes

pathological changes
• Acute pulmonary congestion
– Alveolar capillaries filled with blood – Maybe associated septal edema / intra-alveolar
hemorrhage
Acute pulmonary congestion
Congestion and edema are commonly occur together.
Local increased volume of blood in a particular tissue
HYPEREMIA
CONGESTION
1 Due to arteriolar dilatation Due to impaired outflow
• e.g. skeletal muscle during exercise, in stomach replete with food, and inflammation.
Pathological changes
• Gross: The affected tissue are redder, warm,
Hyperemia
• Hyperemia is an active process resulting from augmented tissue inflow due to arteriolar dilation .
• It’s always a physiological state or is good for body.
Major organs affected
• Subcutaneous tissues • Organs
