چکیده
INTRODUCTION This case report demonstrates that the differential immunohistochemical reactivities of Siemens' Double Antibody Glucagon compared to DakoCytomation's Polyclonal Rabbit Anti-Human Glucagon allow for pathologic distinction of enteral versus pancreatic glucagonoma. CASE PRESENTATION A 64-year-old Caucasian man was diagnosed with a duodenal enteroglucagonoma following presentation with obstructive jaundice. He had a low serum glucagon level using Siemens' Double Antibody Glucagon, a clinical syndrome consistent with glucagon hypersecretion. A periampullary mass biopsy proved to be a neuroendocrine tumor, with positive immunohistochemical reactivity to DakoCytomation's Polyclonal Rabbit Anti-Human Glucagon. CONCLUSIONS Differential comparison of the immunohistochemical reactivities of Siemens' Double Antibody Glucagon and DakoCytomation's Polyclonal Rabbit Anti-Human Glucagon discerns enteroglucagon from pancreatic glucagon.

THE EFFECTS OF GLUCAGON, INSULIN AND S TEROID HORMONES ON PHOSPHATIDATE PHOSPHOHYDROLASE ACTIVITY IN RAT LIVERS
The effects of steroid hormones, glucagon and insulin on rat liver phosphatidate phosphohydrolase (PAP) activity were studied both in vitro and in vivo. Incubation of rat hepatocytes with each hormone showed that dehydroepiandrosterone (DHEA), progesterone and testosterone increase PAP activity by 44.6, 37 and 36.9%, respectively. Estradiol, however, decreased enzyme activity by 13.6% under...
متن کاملDiscovery of Novel Glucagon Receptor Antagonists Using Combined Pharmacophore Modeling and Docking
Glucagon and the glucagon receptor are most important molecules control over blood glucose concentrations. These two molecules are very important to studies of type 2 diabetic patients. In literature, several classes of small molecule antagonists of the human glucagon receptor have been reported. Glucagon receptor antagonist could decrease hepatic glucose output and improve glucose control in d...
