  1. which enzyme is best used for identifying hepatobiliary disease?
    alkalkine phosphatase (ALP)
  2. in which cell does conjugation of bilirubin take place?
    hepatocytes
  3. which fraction of bilirubin is water soluble and reacts with a diazo reagent without addition of accelerator?
    conjugated bilirubin
  4. which enzyme is most useful in establishing the hepatic origin of an elevated serum alkaline phosphatase
    5'-nucleotidase
  5. The reagent p-dimethylaminobenzaldehyde is used to measure what
    urobilinogen
  6. what is the correct expression for creatinine clearance?
    U/P x V x 1.73/A
  7. what happens to arterial blood when exposed to air?
    • PO2 incrs
    • PCO2 decrs
    • PH incrs
  8. what are the variables when O2 dissociation curve shifts left?
    • decrs H+
    • decrs pCO2
    • decrs 2,3 BPG
    • decrs temp
    • left shift means lower affinity
  9. what are the variables when O2 dissociation curve shifts right?
    • incrs H+
    • incrs pCO2
    • incrs 2,3 BPG
    • incrs temp
    • right shift means lower affinity
  10. what condition causes the curve to increase affinity hemoglobin for O2
    alkalosis
  11. what causes increased unconjugated bilirubin in serum
    enterohepatic failure
  12. what increases conjugated bilirubin
    hemolysis
  13. what is the method of measuring bilirubin
    Conjugated Bilirubin + diazotized sulfanilic acid → azobilirubin (purple colored)

    • Total Bilirubin + diazotized sulfanilic acid+ methanol→ purple colored compound
    • Unconjugated bilirubin = Total Bilirubin – conjugated bilirubin
  14. what makes bilirubin soluble
    caff-benzoate
  15. what is the primary function for kidney/renal function
    most prominent functions are removal of unwanted substances from plasma, homeostasis of body's water, electrolyte, acid and base status and hormonal regulation
  16. what is the function of proximal tubule
    • returns bulk of each valuable substance back to the blood
    • 60% water, sodium, and chloride
    • 100% glucose
    • almost all amino acids, vitamins, proteins
    • varying amounts of urea, uric acid, ions
  17. what is the function of the collecting tubule
    • final site for concentrating or diluting urine
    • ADH and aldosterone control, reabsorption of water and sodium
    • chloride and urea are reabsorbed
  18. what occurs in nephrotic syndrom
    protein will increase
  19. what is the test for renal homeostasis for pH
    bicarbonate, serum pH
  20. what is myoglobin and its function
    • myoglobin clearance has been proposed as an effective early indicator of myoglobin induced acute renal failure. Associated with acute skeletal and cardiac muscle injury
    • functions to bind and transport oxygen from the plasma membrane to the mitochondria muscle cells.
    • rhabdomyolsis delivers oxygen
  21. is it true that rhabdomyolysis delivers oxygen?
    true
  22. what parameter is most useful in indicating excess carbon monoxide in blood
    total O2 saturation
  23. what happens to arterial blood in air
    • pCO2 incrs
    • PO2 decrs
  24. what are the two hormones that control exocrine
    secretin and CCK
