type III

2 types of disease?

s- acute due to? chronic from?

a- type of reaction? seen in?

serum sickness (reaction to proteins in serum)

Q

type of staining?

help identigy what? stains what?

Q

describe each picture

what makes them look like that?

which is what type of hypersensitivity reaction?

examples?

Q

type shown in picture?

is a pic of kidney

special about this disease

type IV

can you tell grossly?

ex?

hallmark of some type IV?

what is it made up of? (type of cells)

origin from?

caused by?

Q

type IV diseases?

A

Q

type IV the mantoux test

what is it?

how long for reaction to be assessed?

A

Q

reactions apparent based on presentation?

what is apparent?

reactiosn require knowing behind the scenes?

examples?
