Yellow Eyes
- hepatobiliary system
- The (hepato) part
- The (Biliary) part
- Gallstone impacted in the neck or Hartmann's Pouch
- Mirizzi syndrome
- Mirizzi syndrome
- Gallstone impacted in the neck or Hartmann's Pouch
- Having to do with the liver plus the gallbladder, bile ducts, or bile.
- The (hepato) part
- Hemoglobin metabolism
- Hemoglobin Degradation
- Porphyrin ring is opened by oxidation reaction that is
catalysed by the microsomal haem oxygenase, which requires
NADPH and O2.
- The result of this reaction is linear biliverdin, Carbon
monoxide (CO) and release of Fe 3+.
- Biliverdin (green) is reduced forming a red-orange bilirubin
- Bilirubin is relatively insoluble this is why it binds
non covalently to albumin* to be transported to
the liver.
- At the hepatocytes
- Bilirubin dissociates from albumin and binds to an intracellular protein ligandin.
Microsomal bilirubin UDP-glucuronosyltransferase (bilirubin UGT)* conjugate bilirubin
to two molecules of glucuronic acid♠.

- Jaundice
- Prehepatic
- Causes
- Physiologic
Jaundice
- hemolytic anemia
- Gilbert syndrome
- is a relatively mild condition characterized by periods of elevated levels
of a toxic substance called bilirubin in the blood (hyperbilirubinemia)

- Criggler Naggar
- Crigler–Najjar syndrome or CNS is a rare inherited disorder affecting the
metabolism of bilirubin, a chemical formed from the breakdown of the
heme in red blood cells.

- Causes
- Hepatitis
- Hepatitis B signs and symptoms

- profound malaise
- painful hepatomegaly
- serum sickness prodrome
- vasculitis
- high levels of unconjugated bilirubin
- dark urine due to high levels of Conjugated bilirubin
- Stool color is normal
- Liver enzymes are increased due to damage to the liver
- Liver enzymes are increased due to damage to the liver
- Stool color is normal
- +Conjugated Bilirubin (20-50%)
- dark urine due to high levels of Conjugated bilirubin

- dark urine due to high conjugated bilirubin
- Primary biliary cirrhosis
- Causes
- a yellow discoloration of the skin, mucous membranes, and the whites of
the eyes caused by increased amounts of bilirubin in the blood.
