Summary
Hemoglobin transforms into bile pigment within body cavities, excluding the liver. This demonstrates significant extrahepatic bile pigment formation, proving bile pigments can form without direct liver involvement.
Area of Science:
- Physiology
- Biochemistry
Background:
- Hemoglobin degradation is a key process in the body.
- Bile pigment formation has traditionally been linked to liver function.
Purpose of the Study:
- To investigate the possibility of bile pigment formation outside the liver.
- To determine if hemoglobin can be converted to bile pigment in isolated body cavities.
Main Methods:
- Experiments were conducted involving circulation confined to the head, neck, and thorax.
- Hemoglobin transformation to bile pigment was assessed within pleural and peritoneal cavities.
Main Results:
- Hemoglobin was successfully converted to bile pigment within the pleural and peritoneal cavities.
- Transformation was detectable after eight hours and quantifiable after twenty-four hours.
Conclusions:
- Bile pigment formation can occur independently of direct liver activity.
- Extrahepatic bile pigment formation plays a significant role in physiological processes.

Jaundice
Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...
Pleural Effusion I: Introduction
Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.
There are two main types of pleural effusion: transudative and exudative. They are differentiated using Light's criteria,...

Ascites
DefinitionAscites is the buildup of fluid inside the peritoneal cavity. It occurs when fluid moves out of the vascular system faster than the peritoneal lymphatics can remove it. This fluid shift is most commonly seen in liver cirrhosis but can also appear in several other systemic disorders.EtiologyCirrhosis remains the leading cause of ascites. Other conditions that can contribute include:Heart failureConstrictive pericarditisAbdominal cancersNephrotic syndromeSevere protein–calorie...
Lifecycle of Erythrocytes
Erythrocytes, also known as red blood cells, constantly move through blood capillaries. As a result, they damage their plasma membrane due to the continuous friction. Typically, after 100 to 120 days, erythrocytes become rigid and fragile as they wear out. As they pass through small vessels in the spleen and liver, they can get trapped and break apart into fragments.
The resident phagocytic macrophages deal with these damaged cells by engulfing them and separating their globin and heme groups.

Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Hemoglobin
Hemoglobin is a globular protein made up of four subunits. Two of these subunits are alpha chains, and the other two are beta chains. Each subunit contains a molecule of heme, which has an iron atom and can bind to oxygen. When an oxygen molecule binds to one heme group, it changes the shape of hemoglobin, making it easier for the other heme groups to bind oxygen as well.
When all four heme groups are bound to oxygen, the resulting molecule is called oxyhemoglobin. As a result, arterial blood...
