問題一覧

1

denotes a condition in which the immune response results in exaggerated or inappropriate reactions that are harmful to the host.

hypersensitivity

2

It manifests itself in tissue reactions occurring within seconds after the antigen combines with specific IgE antibody.

Type I: Immediate Hypersensitivity (Allergy)

3

It may take place as a systemic anaphylaxis or as a local reaction like atopic allergy.

Type I: Immediate Hypersensitivity (Allergy)

4

causes vasodilation, increased capillary permeability and smooth muscle contraction

histamine

5

causes bronchoconstriction

prostaglandin

6

causes increased permeability of capillaries

leukotriene

7

It involves the binding of IgG antibody to cell surface antigens or extracellular matrix molecules that can activate complement or effector cells to damage the cells.

Type II: Cytotoxic Reactions

8

This results to a complement-mediated lysis that occurs in hemolytic anemias, ABO transfusion reactions and Rh hemolytic disease.

Type II: Cytotoxic Reactions

9

Immune complexes are formed when an antibody binds with specific antigens. Normally they are removed and excreted out of the body but occasionally they persist and are deposited in tissues, resulting in several disorders.

Type III: Immune Complex Hypersensitivity

10

Type III local immune complex

Arthus reaction

11

Type III systemic immune complex

acute streptococcal glomerulonephritis

12

It involves cell-mediated immune responses and is caused mainly by specifically sensitized T-lymphocytes that activate macrophages to cause an inflammatory response.

Type IV: Cell-Mediated (Delayed) Hypersensitivity

13

The response is delayed – it usually starts 2 to 3 days after contact with the antigen and often lasts for days.

Type IV: Cell-Mediated (Delayed) Hypersensitivity

14

It includes contact hypersensitivity and tuberculin-type hypersensitivity.

Type IV: Cell-Mediated (Delayed) Hypersensitivity
