The typical hepatocyte is cubical with sides of 20-30 μm, (in comparison, a human hair has a diameter of 17 to 180 μm). [1] The typical volume of a hepatocyte is 3.4 x 10 −9 cm 3. [2] Smooth endoplasmic reticulum is abundant in hepatocytes, in contrast to most other cell types. [3]
Hepatocytes constitute about 80% of the cell population of the liver, with the other 20% being occupied by Kupffer cells, hepatic stellate cells, endothelial cells and mesothelial cells, which are not exactly characteristic of the liver, but are present in the liver samples. [2] Histologically speaking, hepatocytes have specific characteristics.
In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue, consisting of portal triads, hepatocytes arranged in linear cords between a capillary network, and a central vein.
Hepatitis D virus is a "satellite" of hepatitis B virus (it can only infect in the presence of hepatitis B), and co-infects nearly 20 million people with hepatitis B, globally. [ 65 ] Hepatic encephalopathy is caused by an accumulation of toxins in the bloodstream that are normally removed by the liver.
Hepatitis B virus DNA remains in the body after infection, and in some people, including those that do not have detectable HBsAg, the disease recurs. [100] [101] Although rare, reactivation is seen most often following alcohol or drug use, [102] or in people with impaired immunity. [103] HBV goes through cycles of replication and non-replication.
GGT is a microsomal enzyme found in hepatocytes, biliary epithelial cells, renal tubules, pancreas, and intestines. It helps in glutathione metabolism by transporting peptides across the cell membrane. Much like ALP, GGT measurements are usually elevated if cholestasis is present. [10]
Six small non-avian dinosaur eggs, no bigger than grapes, were discovered during a field study in Ganzhou, China, in 2021. These eggs now mark the smallest-ever found in the world.
People with hepatitis A are advised to rest, stay hydrated and avoid alcohol. A vaccine is available that will prevent HAV infection for up to 10 years. Hepatitis A can be spread through personal contact, consumption of raw sea food, or drinking contaminated water. This occurs primarily in third world countries. Strict personal hygiene and the ...
