Correlation

Q: Excretion of bile pigments & bile salts into the bile is which function of liver? (Topic: Organ function Tests)

A: Excretory function

Q:  Name the tests based on liver excretory function. (Topic: Organ function Tests)

A: Serum-bilirubin: Total, conjugated and unconjugated

Urine: Bile pigments, bile salts and urobilinogen

Q: Bile pigments are degradation product of? Name the tests for its detection in urine. (Topic: Hemoglobin)

A: Hemoglobin is degraded as bile pigments.

Test for Bilirubin in urine: Van den Bergh’s test, Gmelin’s test, Cole’s test, Fouchet’s test, Ehrlich’s test

Q: Name the vitamin involved in bile pigments degradation. (Topic: Vitamins)

A: Vitamin C is required for degradation of bile pigments.

Q: Precursor for synthesis of bile salts is? Name the tests for its detection in urine. (Topic: Lipids)

A: Bile salts are product of cholesterol.

Tests for bile salts in urine:  Hay’s sulphur powder test, Pettenkoffer’s test, Oliver’s test

Q: Increased urobilinogen in urine, absence of bilirubin in urine and increased stercobilinogen in feces are strongly suggestive of which type of jaundice? (Topic: Organ function Tests)

A: Hemolytic Jaundice.

Q: Mention the normal range of serum total, direct and indirect bilirubin. (Topic: Hemoglobin)

A: Normal range-

Total bilirubin   –              0.2 to 1.0 mg/dl

Direct (conjugated) –        0.2 to 0.4 mg/dl

Indirect (unconjugated) –  0.2 to 0.6 mg/dl

 

Correlation

Q:  Estimation of Total proteins, Serum albumin, globulins, A/G ratio, Prothrombin time is used to assess which function of the liver? (Topic: Organ function Tests)

A: Synthetic function of liver

Q: Albumin, Globulin & plasma proteins are separated by?  (Topic: Amino Acids & Proteins)

A: Electrophoresis

Q:  Mention the functions of plasma protein- albumin. (Topic: Amino Acids & Proteins)

A:  Maintenance of osmotic pressure: Albumin contributes to 75-80 % of total plasma osmotic pressure, Maintains blood volume and body fluid distribution.

Transport functions: Albumin – transport of FFA, Unconjugated bilirubin, Calcium, Copper

Q: Decrease in plasma albumin leads to which clinical condition in one of the Protein-energy malnutrition conditions? (Topic: Nutrition)

A: Bilateral pitting edema with a protruding abdomen in Kwashiorkor as osmotic pressure is not maintained due to albumin deficiency.

Q: Mention the basic cause of Kwashiorkor. (Topic: Nutrition)

A: Protein deficiency in 1–5-year-old children

Q: Name the other type of PEM with severe muscle wasting, no edema, normal serum albumin. (Topic: Nutrition)

A: Marasmus due to calorie restriction in below 1 year infant.

Q: Serum albumin levels are indicator of acute or chronic liver disease? (Topic: Organ function Tests)

A: chronic liver disease- Since albumin has a fairly long half-life of 20 days
