Abstract:
We studied the effect of high-cholesterol diet and factors inhibiting 3-hydroxy-3-methylglutaryl coenzyme A reductase on the development of liver fibrosis in C57Bl/6 mice with CCl4- or zymosan-induced hepatitis. Feeding a high-cholesterol diet led to a sharp increase in collagen content in the liver tissue of animals with CCl4-induced or zymosan-induced hepatitis. Atorvastatin and calcitriol produced less pronounced fibrogenic effects. Mevalonate partially prevented the development of cholesterol-induced fibrogenesis. High-cholesterol diet led to accumulation of oxysterols, cholesterol esters, and triglycerides and increased the expression of transforming growth factor-beta1 mRNA in liver tissue. Cholesterol-induced potentiation of the fibrogenic response is probably associated with transforming growth factor-beta1 induction due to accumulation of lipids and oxysterols in the liver.

Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
