The Molecular Basis of Portal Hypertension
1Charleston, South Carolina.
Abstract:
Cirrhosis leads to portal hypertension and vascular abnormalities in multiple vascular beds. There is intense vasoconstriction in the liver and the kidneys, but also vasodilation in the other vascular beds, including the periphery, lungs, brain, and mesentery. The derangement in each of these beds leads to specific clinical disease. The vasoconstrictive phenotype in the liver ultimately leads to clinical portal hypertension, and is caused by an imbalance of vasoconstrictive and vasorelaxing molecules, which will be the focus of this review.

Hepatic Portal System
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
