Flashcards in Allergies/ Anaphylaxis Deck (28):
1

Diapadesis

"oozing through"

2

Phagocytes

"phago" = eating

3

Macrophages

big eaters, white blood cells

4

Natural killer cells

binds to foreign cell and secrets enzyme

5

Antigen

Antibody generator

6

Antibody's

Tag bad cells for phagocytes
-Purpose is to counteract effects of an antigen by binding and removing
-Body must have been previously exposed

7

B cells

Bone marrow produced

8

T cells

Thymus produced

9

Helper T's

Call the shots

10

Memory T cells

Future immunity

11

Worst means of aquiring an allergic reaction is...

Injection (bee sting, penecilin injection)

12

Deaths from anaphylaxis per year

400-800 people die per year

13

Allergen

Substance that induces hypersensitivity

14

Allergy

exaggerated immune response

15

Autoimmunity

immune response against own cells

16

Isoimmunity

Immune response directed against beneficial foreign tissues (ex: Lupus Disease)

17

Immunoglobulin

Molecule produced to challenge a immunogen

18

Immunoglobulin seen in allergic reaction

IgE

19

Process of allergic reaction

slide 14

20

Mast cells

release histamines when the allergen is encountered

21

Types of reactions

Local
Systemic
Anaphylaxis (systemic, cutaneous- tissue, skin... everything swells)

22

First drug to be administered for anaphylaxis

Oxygen

23

order for epi IV/IO allergic reaction

.1mg IV/IO 1:10,000 BHO

24

What drugs cause extapyramidal reactions

Phenothiazines

25

Phenothiazines

Haldol - Psych
Mellaril - Maintenance
Navane
Stelazine
Compazine – Psych, N/V
Thorazine
Tigan –
Inapsine
Reglan - GI
Torecan
Emetecon
Prolixin

26

Immunogen

Substance capable of immune response or producing immunity

27

Allergy

Antibody-antigen response

Altered body reaction to an antigen

28

Body's defense system

-Skin is acidic, inhospitable to most bacteria
-If foreign substance enters body, the body tries to rid it through…cough, sloughing, vomiting, urinated
-Next step in inflammatory response
-Last line is immune response
