The absorption rate of ethanol is typically modeled as a first-order kinetic process depending on the concentration gradient and specific membrane. The rate of absorption is fastest in the duodenum and jejunum, owing to the larger absorption surface area provided by the villi and microvilli of the small intestines.
[1] [2] The effect is most associated with orally administered medications, but some drugs still undergo first-pass metabolism even when delivered via an alternate route (e.g., IV, IM, etc.). [3] During this metabolism, drug is lost during the process of absorption which is generally related to the liver and gut wall. The liver is the major ...
Folate level is reduced in alcoholic patients due to decreased intestinal absorption, increased bone marrow requirement for folate in the presence of alcohol, and increased urinary loss. The magnitude of leukocytopenia ( white blood cell depletion) reflects severity of liver injury.
Cell membranes are highly permeable to alcohol, so once alcohol is in the bloodstream it can diffuse into nearly every cell in the body. The concentration of alcohol in blood is measured via blood alcohol content (BAC). The amount and circumstances of consumption play a large part in determining the extent of intoxication; for example, eating a ...
A growing body of evidence has shown links between cancer and drinking alcohol. In a warning Friday, U.S. Surgeon General Vivek Murthy said cancer risk increases with the number of drinks, but ...
Murthy said alcohol use is the third leading cause of preventable cancer in the US, after smoking and obesity, and that alcohol products should carry warning labels similar to cigarettes.
Bone resorption is resorption of bone tissue, that is, the process by which osteoclasts break down the tissue in bones [1] and release the minerals, resulting in a transfer of calcium from bone tissue to the blood. [2] The osteoclasts are multi-nucleated cells that contain numerous mitochondria and lysosomes. These are the cells responsible for ...
If approved, Senate Bill 5067 would make Washington the second state to lower its per se blood alcohol concentration, or BAC.) limit for driving, from .08% to .05%.
