Oxygen free radicals in acute pancreatitis of the rat.
This study aimed to assess the role of oxygen free radicals in acute pancreatitis. Acute pancreatitis was induced in rats by infusion of the CCK-analogue cerulein (5 micrograms/kg per hour) for 30 minutes, 3.5 hours, and 12 hours. After the infusion, serum enzymes and conjugated tissue dienes and malondialdehyde were measured and tissue samples were subjected to electron and light microscopy. E...
متن کاملThe Role of Leucoyte-Derived Free Oxygen Radicals in the Pathogenesis of Experimental Acute Pancreatitis
The role of free oxygen radicals in experimental acute pancreatitis induced by common bile duct ligation was investigated by measuring malondialdehyde levels in the rat pancreas. Also, the potential role of leucocytes as the source of free oxygen radicals was tested by inducing leukopenia with methotrexate. The malondialdehyde levels in the control, pancreatitis and pancreatitis + methotrexate ...
متن کاملRole of oxygen and nitrogen free radicals in diabetes-induced atherosclerosis and effects of exercise on it
Free radical can be defined as a molecule or molecular fragments containing unpaired electron in the outer orbital, which react with nearby molecules to get stability. There are two types of them in the body: oxygen free radicals and nitrogen free radicals. Our body has an antioxidant defense system which prevents accumulation of these radicals. There is a balance between free radical produc...
متن کاملOxygen in Biology and Biochemistry: Role of Free Radicals
A free radical is defined as any atom or molecule that contains unpaired electrons and has independent existence (hence, the term free). A dot is used to represent a free radical species. The abstraction or gain of one electron by a nonradical molecule may (or may not) convert it to a radical species. Free radicals can have positive, negative, or neutral charges [reactions (12.1.1) and (12.1.2)].
