answered to pass
1. Creatinine
enzyme found mainly in the heart, brain and skeletal
phos-
muscle. CPK has 2 basic chains M (muscle) B
phokinase
(brain)
(CPK)
CPK-BB
2. Brain-CPK
almost entirely
BB
CPK-MB
3. Cardiac-CPK is
60% MM and 40% Rises only when heart muscle damaged, appears 1st 6-24 hrs. gone
in 72 hrs.-3
MB days
4. Skeletal muscle is CPK-MM
90% MM and 10% appears 4-12 hrs. peaks 24 hrs. returns to normal 3-4 days
MB
5. Total CPK 5-35
Normal Male
6. Total CPK 5-25
Normal Female
7. CPK-BB 0% of total CK
8. CPK-MB 0-7% of total CK
9. CPK-MM 5-70% of total CK
