Cytotoxic hypersensitivity. Antibody-mediated destruction of healthy cells.
Ex: Transfusion reaction with incompatible blood donor

Increase in number of cells
Hemolytic disease of the newborn
Give this one a try later!
Antigen-antibody reaction between a mother's antibodies and her
newborn infant's RBCs at the time of birth. Maternal antibodies (IgM) are
usually against A, B, or Rh surface antigens on newborn RBCs.
Infants are treated with sunlight or phototherapy to break down excess
bilirubin.
Interleukins

Proteins (cytokines) that stimulate the growth of B and T lymphocytes

Give this one a try later!
, Inflammatory cytokine secreted by macrophages
Induces fever, loss of appetite, and lethargy

Give this one a try later!
aka meningococcus
A gram-negative bacteria that is a common cause of bacterial meningitis.
Can cause outbreaks in people living in close quarters (ex: prisons, dorms,
etc)
Vaccine is available.
Heparin
Give this one a try later!
Anticoagulant that works by activating antithrombin (AT), the body's natural
clot-dissolving substance
Produced endogenously by mast cells and basophils, or can be
administered intravenously.
Mast cells
Give this one a try later!
, Granulocyte that releases large amounts of histamine
Similar to basophils, but not found in blood
Mycoplasma pneumoniae
Give this one a try later!
"Walking pneumonia"
Gangrene
Give this one a try later!
Condition when prolonged ischemia causes tissue necrosis followed by
bacterial infection
