A 51-year-old woman had been administered 5 mg/day of prednisolone due to systemic lupus erythematosus (SLE). She developed hypertension, hypokalemia and a pathologic pubic fracture during two years before admission. Although iatrogenic Cushing's syndrome was initially suspected, we diagnosed her as concomitant Cushing's syndrome due to a left adrenal tumor.

She had been followed-up for chronic pericardial effusion detected by echocardiography 10 years previously. Initial echocardiography showed that the left ventricular diastolic diameter (LVDd) was 39 mm and percent fractional shortening (%FS) was 33.

Caerulein at a concentration of 0.1 ng/ml which is a submaximal concentration for an effect on exocrine pancreatic secretion potentiated insulin responses to glucose concentrations less than 200 mg/dl, but produced no further increase when added to a glucose stimulus over a 200 mg/dl.

The tumor-bearing pancreas secreted significant amounts of insulin even at 2.8 mM glucose stimulation.
View Article and Find Full Text PDFPancreatic exocrine and endocrine secretory dynamics were studied in the isolated perfused pancreata of rats fed a normal diet or a diet supplemented with the alpha-glucosidase inhibitor, acarbose (150 mg/100 g food). After 10 days, the body weight of acarbose-treated rats was slightly lower than that of the control rats despite a larger food intake. Pancreatic amylase levels were significantly decreased, trypsinogen levels were significantly increased, and lipase levels were unaltered in the treated group compared with the controls.

Although recent studies by column chromatography and electrophoresis showed that elevated amylase activity in the body fluids and tumor extracts in patients with primary lung cancer was mainly in the salivary-type isoamylase, neither mechanism nor mature of elevation of amylase have been clarified yet. This study was undertaken in order to make clear the nature of amylase elevated in the body fluids and tumor extracts of patients with primary lung cancer. In addition, amylase contained in the extracts of normal lungs and diseased lungs of patients who had died of various diseases was also studied.

The mode of inhibition of a new complex oligosaccharide that inhibits the alpha-glucoside hydrolase activity of pancreatic and salivary alpha-amylase was studied. Kinetic analysis revealed a non-competitive type of inhibition with a Ki of 1.47 +/- 0.
View Article and Find Full Text PDFThe effects of both synthetic and pure natural porcine secretin on immunoreactive insulin (IRI) and immunoreactive glucagon (IRG) release and on pancreatic exocrine secretion were studied in the isolated perfused rat pancreas. Synthetic porcine secretin stimulated a significant increase in pancreatic juice flow and amylase output at concentrations as low as 0.01 and 0.
View Article and Find Full Text PDFPortal plasma immunoreactive secretin (IRS) concentrations, pancreatic juice flow, and amylase output were simultaneously measured in response to intraduodenal infusion of 1-phenyl-1-hydroxy-n-pentane (PHP), as well as infusion of hydrochloric acid (HCl). These data were compared with those obtained from intravenous bolus injections of synthetic porcine secretin in anesthetized rats. The intraduodenal infusion of PHP or HCl at a rate of 2 ml/min for 2 min produced a dose-related increase in portal plasma secretin concentrations, pancreatic juice flow, and amylase output.
View Article and Find Full Text PDFPancreatic juice flow and amylase output, and the concentrations of immunoreactive secretin in portal and peripheral blood were simultaneously determined in anesthetized rats in response to intraduodenal instillation of 1-phenyl-1-hydroxy-n-pentane (PHP), a phenyl carbinol derivative induced from one of the constituents of Curcuma. PHP stimulated both pancreatic juice flow and amylase output and increased portal and jugular plasma secretin levels in a dose-related fashion. During intraduodenal instillation of PHP the pH in the second portion of the duodenum remained consistently above 6.
