Nesidioblastosis is a rare cause of endogenous hyperinsulinemic hypoglycemia in adults. Diagnosis is often challenging and therapeutic options are scarce.In 2009, a 46-year-old female patient presented with recurrent severe hypoglycemia and immediate recovery after glucose ingestion. Although 72-h-fasting test was positive, various imaging technologies (sonography, computed tomography, somatost...

A novel pituitary protein "7B2" was secreted by GH1 cells. The secretion of 7B2 was increased in the presence of human GRF in a dose-responsive manner. In contrast, a somatostatin analog, SMS 201-995, revealed the inhibitory effects on the basal- and GRF-induced secretion of 7B2 at the concentration of 10(-7) M. These findings suggest that 7B2 is a secretory protein of rat GH1 cells under certa...

Somatostatin analoges labeled with different radionuclides are able used for imaging and treatment of somatostatin receptor positive tumors. In this study Tyr³-Octreotide protected at lysine as an analoge of somatostatin was conjugated with bifunctional chelating agent 6-BOC-hydrazinopyridine-3-carboxylic acid (BOC-HYNIC) and after deprotecting of conjugate, purification was performed wit...

The present study examined nociceptive behaviors and the expression of phosphorylated cAMP response element-binding protein (pCREB) in the dorsal horn of the lumbar spinal cord and the dorsal root ganglion (DRG) evoked by bee venom (BV). The effect of intraplantar preapplication of the somatostatin analog octreotide on nociceptive behaviors and pCREB expression was also examined. Subcutaneous i...

As previously shown with adenosine, somatostatin, which is ineffective alone, enhanced the alpha 1-adrenergic-agonist-stimulated production of inositol phosphates in cultured striatal astrocytes. This effect was suppressed in cells pretreated with pertussis toxin. It required external calcium and was selectively antagonized by both mepacrine, an inhibitor of phospholipase A2, and 5,8,11,14-eico...

PURPOSE Androgen ablation-refractory prostate cancer patients (stage D3) develop painful bone metastases and limited responsiveness to conventional therapies, hence the lack of universally accepted "gold standard" treatment for this poor prognosis clinical setting. We tested the safety and efficacy in stage D3 patients of the combination hormonal therapy, which combines administration of somato...
