Cards

Term
Functional Enzymes
Definition
plasma, functions in plasma, lipoprotein, pseudocholine,
Term
non-functional enzymes
Definition
min concentrations, no known function in plasma,
Term
altered enzyme activity differe effects
Definition
myocardial infaraction
increased cell turn over- hyerparathyroidism
cell proliferation - cancer
enzyme induction - alcohol
Term
three factors effecting diagnosis
Definition
levels, ratio to isoenzymes, timining
Term
criteria for enzymes in diagonosis
Definition
cheapy and easy, specific, levels should be proportional to severity of disease, early the better,
Term
isoenzyme
Definition
distinct forms of the same enzymes,
Term
True isoenzymes
Definition
formed from different genes cytosolic, MDH
Term
Hybrid isoenzymes
Definition
made up of different subunits, LDH
Term
allozymes
Definition
same locus has different alleles, different forms in different individuals
Term
isoforms
Definition
isoforms, individuals: sialic acid content ALP isoforms.
Term
separation of isoenzymes
Definition
electrophoresis
Term
LDH and myocardial infaraction
Definition
endothelial cells will rupture, serum levels for LDH 1 and 2 increase, NOrmal is 100-200
Term
LDH and myocardial infarction in terms of LD1 and LD2 enzymes
Definition
Muscles:LD1,LD2
Blood:LD2, LD1 Shifts in MI
Term
CK Isoenzymes and tissues of origin
Definition
MM(Ck3) Muscle
MB(Ck2) Heart
3-6 hours 15-100 u/l and 10-80
BB(Ck1) Brain
Term
What CK is used to detect MI
Definition
Heart(mB), because muscle is too large in quantity.
Term
Adv over LDH
Definition
CK is not increased in hemolyrcis or congestive cardiac failrue
Term
Cardiac muscle disease
Definition
muscular dystrophy increases it, total CK is used in this case
Term
Duration of enzymes for Acute MI
Definition
Ck-mb 3-10 12-24 1.5-3
Ck 5-12 18-30
AST 6-12 20-30
LD 8-16 30-48 5-14
Term
Muscular disorder diagnosis enzymes and purpose
Definition
CK- specific
AST: increase in different types but not specific
Aldolase: converts fructose-1, 6-bisphosphate to DHAP and Glycealdehyde
Term
AST main functions
Definition
significant increase in MI
Elevated in liver diseases
2 iso-enzymes- cytoplasmic and mitochondrial
Term
ALT vs AST normal levels
Definition
AST 8-20
ALT- 10-40
increase in liver diseases but ALT more except alcohol
Term
GGT( Gamma Glutamyl transferase
Definition
GGT elevated in alcohol and jaundice, management of hepatitis
Term
Hepatic Disease enzymes
Definition
ALT, NTP,ALP, GGT
Term
Bone Disease
Definition
ALP
Term
Prostate Cancer
Definition
PSA, ACP
Term
Streptokinase and Urokinase
Definition
used in MI
Term
pepsin and trypsin
Definition
indigestion
Term
asparaginase
Definition
anticancer
