Octreotide-induced drinking, vasopressin, and pressure responses: role of central angiotensin and ACh.
The involvement of central angiotensinergic and cholinergic mechanisms in the effects of the intracerebroventricularly injected somatostatin analog octreotide (Oct) on drinking, blood pressure, and vasopressin secretion in the rat was investigated. Intracerebroventricular Oct elicited prompt drinking lasting for 10 min. Water consumption depended on the dose of Oct (0.01, 0.1, and 0. 4 microgra...
متن کاملPreparation, formulation and quality control of one step kit 99mTc- EDDA/HYNIC-Tyr3-Octreotide as a peptide radiopharmaceutical for imaging somatostatin receptor positive tumors [Persian]
The high expression of somatostatin receptors in many tumours, have made receptor scintigraphy with 111In-DTPA-Octreotide a widly used procedure in nuclear medicine. Despite its clinical success, some limitation and drawbacks of radiolabelling with 111In remain, especially those concerned with the cost, availability and physical decay properties of this radionuclide. 99mTc-EDDA/HYNIC-Tyr3...
متن کاملCortistatin radioligand binding in wild-type and somatostatin receptor-deficient mouse brain.
Cortistatin-14 (CST-14) is a recently discovered member of the somatostatin family of neuropeptides. It shares 11 of its 14 amino acids with somatostatin-14 (SRIF-14). In the present study, binding sites for cortistatin-14 in the mouse brain were examined and compared to those for somatostatin using iodinated cortistatin-14 and iodinated somatostatin-14. By in vitro receptor autoradiography, hi...
متن کاملSynthesis, labeling, formulation and quality control of 99mTc-Tricine-HYNIC-Tyr³-Octreotide, a peptide radiopharmaceutical for imaging Somatostatin receptor positive tumors [Persian]
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...
متن کاملCortistatin and pituitary hormone secretion in rat.
Cortistatin (CST), a novel neuropeptide, shows high structural homology and functional resemblance with somatostatin. CST binds with high affinity to all somatostatin receptors, and contrary to somatostatin, is also able to bind with MrgX2 and GH secretagogue receptor of ghrelin (GHS-R1) receptors. The aim of the present investigation was to evaluate in vivo the effect of peripheral administrat...
