1) initiation
2) Elongation
3) Termination
Question>> 1
What is a vaccination?
Answer>>
Injection of antigens;
Antigens from dead microorganisms
Question>> 2
Treatments for allergies?
Answer>>
Immunotherapy
Prescription medication in the form of pills or liquid, nasal sprays, or eye
drops Avoiding allergins
Question>> 3
What is immunotherapy?
Answer>>
desensitization or hypo-sensitization, is a medical treatment for
environmental allergies, such as insect bites, and asthma. Immunotherapy
involves exposing people to larger and larger amounts of allergen in an
attempt to change the immune system's response
Question>> 4
,Oral immunotherapy
Answer>>
Making sure that you do this at hospital not home because you might
need medicial attention
Question>> 5 Identifying allergies Answer>>
Skin test: a drop of a suspected allergen is pricked on the surface of the
skin. The test is
performed on the back or forearm. Many suspected allergens are tested
at the same time. If you are allergic to one of the tests, you will have
redness and swelling at the test spot.
Question>> 6
Advtanges of Passive Immunization
Answer>>
Immediate protection
Question>> 7
Disadvantages of Passive Immunization
Answer>>
- no long term proection
- Risk of infection with unknown pathogens (e.g. 80's - hepatitis B/C
and AIDS
- Serum sickness - Ex. receiving antibodies from a horse serum, could
develop (one day) negative immune response and cause "Serum Sickness"
Question>> 8
Functions of Agglutination
Answer>>
To bind to a certain antigen/pathogen and to counter its effect
Question>> 9 Neutralization Answer>>
Ab "neutralizes" toxins, binds to attachment molecules
,Question>> 10 Agglutination Answer>>
is the clumping of particles. The process that occurs if an antigen is mixed
with corresponding antibody called isoagglutinin. This term is commonly
used in blood grouping .
Question>> 11 Precipitation Answer>>
cannot see with naked eye - not large enough to see the proteins
Question>> 12 Opsonization Answer>>
by antibiotic (Ab) - Fc receptors - triggers phagocytosis
"neutrophil/microphage" = phagocytosis
Question>> 13
Lytic attack pathway
Answer>>
assembly of the lytic complex - a way to kill bacterial cells through
compliment activation
Question>> 14
How to protect a baby from hepatits B transmission from mother
Answer>>
- baby shots for hepatits B (CDC recommendations)
- birth (if mom HBV +)
- H-BIG: Hepatits B immune globulin. Passively delivered antibody that
provides "instant" protection against HBV + Hepatitis B Vaccine
- 1-2 months old: Hepatitis B vaccine + 6 months: Hepatitis B vaccine
- 19 out of 20 babies who get the shots will be protected for life
Question>> 15
Antigen
Answer>>
are substances that induce a specific immune response
Question>> 16
, Antibodies
Answer>>
protein molecules that bind specifically to an antigen
Question>> 17
Prevention and Therapy of Infections
Answer>>
Most of the damage to cells during infections occurs very early, often
before the clinical symptoms of disease appear: this makes drugs
treatment of infection irrelevant in many cases, prevention of infection is
better and cheaper
Question>> 18
What is a vaccine?
Answer>>
- They are harmless agents, perceived as enemies
- They trigger active immunity, stimulating the body to defend itself
- It is about separating pathogenicity vs protection
- They provide protective immunity against a potential pathogen
Question>> 19
vaccination and passive immunization
Answer>>
Antigens(Ag)
- substance that induce specific immune response
- when were are injecting vaccine we are injecting antigen
passive immunization taking product of immune system antibody and
injecting it to people
