Somatostatin is a potent inhibitor of gastrin secretion and gene expression. Menin is a 67-kDa protein product of the multiple endocrine neoplasia type 1 (MEN1) gene that when mutated leads to duodenal gastrinomas, a tumor that overproduces the hormone gastrin. These observations suggest that menin might normally inhibit gastrin gene expression in its role as a tumor suppressor. Since somatosta...

1. It has been reported that ortreotide partially corrects the hyperdynamic state in patients and animals with portal hypertension. The aim of the present study was to investigate whether chronic administration of octreotide can increase vascular responsiveness in rats with portal hypertension. 2. Portal hypertension was induced by partial portal vein ligation. Octreotide was given for 9 days s...

BACKGROUND Studies of treatment with octreotide of patients with hepatocellular carcinoma (HCC) gave conflicting results. We analyzed retrospectively the survival of our patients treated with octreotide monotherapy and compared it to stage-matched patients who received either TACE, multimodal therapy or palliative care. METHODS 95 patients seen at the department of Gastroenterology and Hepato...

1. To determine whether treatment with octreotide, a somatostatin analogue, may diminish or prevent long-term diabetic renal hypertrophy and nephropathy, uninephrectomized streptozotocin-diabetic rats maintained under moderate glycaemic control (approximately 300 mg/dl) were treated with either placebo (n = 10 rat/group) or octreotide for 14 weeks. Uninephrectomized non-diabetic rats given eith...

Jonassen, Thomas E. N., Sten Christensen, Niels Marcussen, and Jørgen Søberg Petersen. Intrarenal octreotide treatment prevents sodium retention in liver cirrhotic rats: evidence for direct effects within the thick ascending limb of Henle’s loop. Am J Physiol Renal Physiol 291: F537–F545, 2006. First published January 17, 2006; doi:10.1152/ajprenal.00226.2005.—We have previously shown that syst...

BACKGROUND/AIMS Amelioration of intestinal dysmotility and stasis during the early period of acute necrotizing pancreatitis (ANP) appears to be important to reduce the risks of secondary pancreatic infection. We aimed to characterize the association between the neuropathy of the enteric nervous system and gut dysfunction and to examine the effect of octreotide on motor innervation in the early ...

OBJECTIVE To evaluate expression of somatostatin receptor subtypes 2 and 5 (SSTR 2 and 5) by RT/PCR and immunohistochemistry (IHC) in GH-secreting adenomas, seeking correlations with response to octreotide. METHODS SSTR2 and 5 expression was tested by IHC (n=37), RT/PCR (n=36) or both (n=13) in GH-secreting adenomas from 60 patients with acromegaly who had undergone pituitary surgery; 36 had ...

Ocular diseases such as proliferative diabetic retinopathy are the major cause of blindness in industrialized countries. The main pathologic features of these diseases are hypoxia and overproduction of growth factors resulting in pathologic proliferation of endothelial cells and new vessel formation. Particularly, hypoxia and growth factors, such as VEGF, IGF-1, bFGF and TGF beta(2), show a com...

OBJECTIVE To study the effectiveness of octreotide in managing chyle fistula neck and its effect on duration of hospitalization. STUDY DESIGN Prospective study. METHODS A total of 19 patients with chyle fistula following neck dissection over a period of 10 years were included in the study. All the patients first underwent conservative management of the chyle leak, including suction drainage...
