Incubation of rat hepatocytes with epinephrine inhibited alanine aminotransferase (ALT) (80%) and aspartate aminotransferase (AST) (53%) activities with no effect on lactate dehydrogenase (LDH) activity. Injection of epinephrine caused a progressive increase with time in hepatic LDH activity, being 52% at 24 h. Preinjection with propranolol eliminated the hormone effect and caused further ...

This report presents a rare case with the synchronous occurrence of advanced neuroendocrine carcinoma (NEC) and tubular adenocarcinoma of the rectum. A 52-year-old Japanese male presented with general fatigue and bloody stool. Endoscopic examination showed an ulcerated lesion of the lower rectum. The pathological diagnosis of biopsy specimens from this lesion indicated moderately differentiated...

Pancreatolithiasis is a risk factor for developing pancreatic cancer. We report here a rare case of sarcomatoid carcinoma of the pancreas in a 55-year old diabetic male associated with pancreatolithiasis. CT scan of abdomen revealed a large operable mass occupying the distal body and tail of the pancreas. Per-operative survey revealed a small metastatic nodule in the surface of hepatic segment ...

Purpose: To assess quantitatively and qualitatively the enhancement effects and the enhancement patterns of hepatic hemangioma and normal liver tissue on contrast-enhanced MR imaging (CE-MRI) obtained with gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA). Methods and Materials: A total of 22 patients with 32 hepatic hemangiomas (high flow type=23, low flow type=9) in no...

Liver tumours are fortunately rare in children. Benign tumours such as haemangiomas and cystic mesenchymal hamartomas are typically seen in infancy, often before 6 months of age. After that age, malignant hepatic tumours increase in frequency. The differentiation of a malignant from benign lesion on imaging can often negate the need for biopsy. Ultrasound is currently the main screening tool fo...

The role of hepatic lipase as a multifunctional protein that modulates lipoprotein metabolism and atherosclerosis has been extensively documented over the last decade. Hepatic lipase functions as a lipolytic enzyme that hydrolyzes triglycerides and phospholipids present in circulating plasma lipoproteins. Hepatic lipase also serves as a ligand that facilitates lipoprotein uptake by cell surface...

OBJECTIVES Our aim was to compare retrospectively hepatic venous and delayed phase images for the detection of tumour washout during multiphasic multidetector row CT (MDCT) of the liver in patients with hepatocellular carcinoma (HCC). METHODS 30 cirrhotic patients underwent multiphasic MDCT in the 90 days before liver transplantation. MDCT was performed before contrast medium administration a...

Reactive lymphoid hyperplasia (RLH) is a rare benign condition that forms a mass-like lesion characterized by proliferation of nonneoplastic lymphocytes forming follicles and germinal centers. RLH is thought to represent a reactive immunological response, and some cases may arise in association with malignancy and hepatitis. Radiologically, RLH of the liver may mimic a primary or metastatic hep...
