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

Chapter 5. Neoplasia
Tumors is common diseases. Bad news: Malignant tumor (cancer) is the
second leading cause of death in some countries. (The first leading cause is cardiovascular diseases.) According to American Cancer Society estimates, in 2003, about 23% of all deaths in the United States (1500 cancer deaths per day).
• A more scientific difinition: “Neoplasia is genetic disease, in which the growth of tumors is loss of responsiveness to normal growth control, and shows an excessive hyperplasia with abnormal differentiation.”
• Oncology is the study of tumors or neoplasms.
• Cancer is the common term for all malignant tumors.
2020/5/14
Neoplasia
• In 1953, The eminent British oncologist Willis had given neoplasia a famous definition: “A neoplasm is an abnormal mass of tissue, the growth of which exceeds and is uncoordinated with that of the normal tissues and persists in the same excessive manner after cessation of the stimuli which evoked the change.”
Tumor (neoplasm):
under the stimulation of tumorgenic agents a single cell of local tissue loss the controlling to its growth at the gene level excessive proliferation to form
