A 57-year-old man with generalized, subcutaneous fat necrosis was found at autopsy to have islet cell carcinoma of the pancreas. The histologic diagnosis of islet cell carcinoma was confirmed by the finding by electron microscopy of characteristic intracytoplasmic granules within pancreatic
Multiple subcutaneous plaques and nodules appeared on the back and the dorsal proximal area of the extremities of a 9-day-old male infant after a complicated prenatal period necessitating cesarean section. The clinical and histological features were diagnostic of subcutaneous fat necrosis of the
BACKGROUND
Obesity is a prognostic factor for severity in acute pancreatitis in humans. Our aim was to assess the role of oxidative stress and abdominal fat in the increased severity of acute pancreatitis in obese rats.
METHODS
Taurocholate-induced acute pancreatitis was performed in lean and obese
Calciphylaxis (calcific uremic arteriolopathy) is a poorly understood and highly morbid syndrome of both vascular calcification and skin necrosis. The main histopathological finding is calcium deposits within arteriolar and small vessel walls, showing endovascular fibrosis associated with fat
Pathological alterations of chronic Achilles paratenonitis were studied histologically and histochemically in tissue samples obtained operatively from 16 athletes with this complaint and from 3 control patients. The activities of 11 different enzymes--lactate, succinate, malate, glucose-6-phosphate
Experiments on rats have demonstrated that changes in the serotonin level in the body intensifies pancreatic function. The pancreas shows the increased contents of trypsinogen and proelastase and those of lysosomal enzymes (cathepsins and acid phosphatase). Administration of serotonin leads to the
The activity of lysosomal enzymes of the pancreas and the liver has been studied during induction and onset of acute hemorrhagic pancreatic necrosis with fat necrosis (AHPN) in mice. We induced AHPN by feeding the animals a choline-deficient (CD) diet containing 0.5% DL-ethionine (CDE). Control
Pancreatic hyperstimulation with simultaneous duct obstruction does not cause the typical features of acute pancreatitis, therefore the role of an additional challenge, such as either ethanol intoxication or short-term ischemia, was studied. Alcoholic pancreatitis was induced in 28 rats by acute
In a model developed to study acute pancreatitis in the dog, the disease process was comparable with the spontaneously occurring disease. Infusion of oleic acid into the accessory pancreatic duct induced, grossly and microscopically, acute hemorrhagic pancreatitis with pancreatic atrophy, fibrosis,
Alcohol can induce adipogenesis by bone marrow stromal cells and may cause osteonecrosis of the femoral head. Currently, there are no medications available to prevent alcohol-induced osteonecrosis. We hypothesized puerarin, a Chinese herbal medicine with antioxidative and antithrombotic effects, can
