The influence of bile-duct obstruction upon basal plasma glucagon levels and the relationship between glucagon-like substance in bile and postobstructive plasma glucagon were examined in the rabbit. Immunoreactive glucagon (IRG) was measured with antiserum 30 K (Unger). Bile-duct obstruction was followed by a prompt rise within 60 minutes in plasma IRG which was four times the basal value, but ...

Acute and chronic pancreatitis may lead to local complications as a result of ductal injury. In the setting of acute pancreatitis the main pancreatic duct or its side branches may be disrupted. These ductal injuries can be minimal and associated with leakage of only fluid, or severe with necrosis of a large amount of pancreatic parenchyma along with the duct lying in the same area.1,2 The seque...

OBJECTIVES Many factors influence the outcome of endoscopic dacryocystorhinostomy (DCR). One of the most important prognostic factors is the level of obstruction in the lacrimal drainage system. The main objective of this report is to evaluate both the frequency of obstruction by anatomical region of the lacrimal drainage system on dacryocystography (DCG) and the surgical outcome of endoscopic ...

Background & objective Regarding the importance of histologic examination of testicular biopsy for clinical planning of infertility, the current study was conducted to compare 2 separate histologic examination of testicular biopsy. Also, some cases with known fertility outcome were followed and their histological patterns were also compared with those of the outcome. Methods The current study...

. PURPOSE Dacryocystorhinostomy (DCR) is the standard surgical treatment for adult nasolacrimal duct obstruction. There have been relatively few studies of closed nasolacrimal duct intubation in adults. The aim of this study was to determine rates of anatomic patency following this procedure. METHODS The authors carried out a survey of all patients undergoing closed nasolacrimal duct intuba...

Gallstone pancreatitis was first recognized as an entity by Opie in 1901 (1), and since then has generated volumes of literature which have attempted to explain its pathophysiology. Multiple animal experiments and human clinical studies in the past thirty years have led to a better understanding of both macro- and microscopic events which lead to pancreatic inflammation in the setting of a pass...
