  • 3rd side (hint)
non-specific body defense occuring in response to injury or antigen
chemical released by mast cells in response to antigen

- dilation of blood vessels
- smooth muscle constriction
- tissue swelling
- itching
causes effects similar to histamine

stored & released by mast cells
vasodilator that causes pain

effects similar to those of histamine
series of proteins combined together in cascade fashion to neutralize or destroy and antigen
- increased capillary permiability
- WBC attraction to inflammation site
- pain

stored & released by mast cells
mast cells
located in tissue spaces under epithelial membranes
(skin, bronchial tree, digestive tract, & along blood vessels)

detect foreign agents or injury & respond by releasing histamine
increase in blood supply to tissue causing redness, pain, and swelling
acute allergic response to antigen resulting in severe hypotension

may cause death if untreated
- itching
- pain
- edema
- vasodilation
- bronchoconstriction

located in smooth muscle of vascular system
causes secretion of large amounts of hydrochloric acid in stomach (where they're located)
foreign substances that elicit a specific immune response
primary cell of immune system that interacts w/antigens
humoral immunity
body defense mechanism involving production & release of antibodies

initiated when antigen encounters a B cell (type of lymphocyte)
B cell
essential lymphocyte for humoral immune response

makes plasma cell 'clones' of itself
plasma cells
cell derived from B cells that produces antibodies

protein produced by body in response to antigen
immunoglobulins (Ig)
AKA antibodies

proteins produced by the body in response to an antigen
memory B cells
remember previous antigen interaction
helper T cells
lymphocyte responsible for activating most other immune cells (includes B cells)

coordinates humoral & cell-mediated immune responses

target of human immunodeficiency virus
cytotoxic T Cells
lymphocyte that directly attacks & destroys antigens
produced by WBCs (interleukins - leukotrienes - interferon - tumornecrosis factor) that guide immune response
memory T cells
T-lymphocyte that remembers previous exposure to antigen
allergic rhinitis
AKA hay fever

sneezing, itchy throat, watery eyes, & nasal congestion resulting from exposure to antigens
H1-receptor antagonists
AKA antihistamines

blocks effects of histamine in smooth muscle in bronchial tree
poisoning due to aspirin & aspirin-like drugs

S/S: tinnitus - dizziness - headache - sweating
ringing in the ears
alternate-day therapy
drug taken every other day to minimize side effects
Cushing's syndrome
too much corticosteroids in blood
transplant rejection
immune system recognizes a transplanted tissue as foreign & attacks it
drugs given to dampen immune response
biological products that prevent disease
AKA immunization

receivinig a vaccine or toxoid to prevent disease
substance chemically modified to remove harmful nature but is still able to elicit immune response from body
additional dose of vaccine given months/years after initial dose to increase effectiveness of vaccine
measurement of amount of antibody produced by body after vaccine has been administered
AKA: Benadryl
CLASS: H1-receptor antagonist
ACTION: 1st gen. antihistamine - reduces inflammation - blocks H1 receptors w/i smooth muscle cells of resp tract & endothelial cells lining blood vessels in skin
A/E: signifcant drowsiness - CNS stimulation - dry mouth - tachycardia - mild hypotension
H1-receptor antagonist
AKA: Allegra
CLASS: H1-receptor antagonist
ACTION: 2nd gen. antihistamine - blocks effects of histamine at H1 receptor
A/E: drowsiness - upset stomach
H1-receptor antagonist
AKA: Flonase
CLASS: intranasal glucocorticoid
ACTION: decreases local inflammation in nasal passage
A/E: nasal irritation & bleeding
intranasal glucocorticoid
AKA: Beconase - Vancenase
CLASS: intranasal glucocorticoid
ACTION: decreases local inflammation in nasal passage
A/E: nasal irritation & bleeding
intranasal glucocorticoid
AKA: Afrin - NeoSynephrine
CLASS: sympathomimetic
ACTION: stimulates alpha-adrenergic receptor of sympathetic nervous system - causes small arterioles in nasal passages to constrict - produces drying of mucous membranes
A/E: rebound congestion - minor stinging - nasal dryness
pseudoephedrine hydrochloride
AKA: Sudafed
CLASS: sympathomimetic
ACTION: stimulates alpha-adrenergic receptor of sympathetic nervous system - causes small arterioles in nasal passages to constrict - produces drying of mucous membranes
A/E: rebound congestion
AKA: Naprosyn - Aleve
CLASS: nonsteroidal anti-inflammatory drug (NSAID)
ACTION: inhibits prostaglandin synthesis through non-selective inhibition of COX-1 and COX-2 enzymes
A/E: GI upset - dizziness - drowsiness - prolonged bleeding time
nonsteroidal anti-inflammatory drug (NSAID)
AKA: Meticorten - Prelone
CLASS: glucocorticoid
ACTION: suppresshistamine & prostaglandins - inhibit immunity by suppressing functions of phagocytes & lymphocytes - combined effects reduce inflammation
A/E: Chusing's syndrome - elevated glucose - gastriculcers - weakness - bruising
AKA: Neoral - Sandimmune
CLASS: immunosuppressant
ACTION: inhibits helper T cells
A/E: reduction of urine flow - tremor - htn - ^ hepatic enzyme values
Long-term therapy with glucocorticoids may result in Chushing's syndrome.
