receptor scintigraphy due to an accessory spleen.
analogues (octreotide and lanreotide) target somatostatin
receptors commonly expressed in pancreatic NET and can lead to decreased hormone production, although they often have limited tumor regression effects (18).
receptors are present in 70% to 90% of NETs.
receptor (SSTR) scintigraphy is a whole-body imaging technique used for diagnosis, staging and restaging of NETs.
The use of radiolabeled somatostatin
analog scintigraphy in the staging of small cell lung cancer patients.
68Ga-DOTA-Tyr3-octreotide PET in neuroendocrine tumors: comparison with somatostatin
receptor scintigraphy and CT.
Glandular duodenal carcinoid--a somatostatin
rich tumour with neuroendocrine associations.
Nicolato evaluated the prognostic role of somatostatin
receptor scintigraphy with the indium-111-labeled somatostatin
analogue octreotide in 12 patients with skull base meningiomas who had undergone gamma knife radiosurgery.
During aging there are several changes which contribute to the decline in GH/IGF-I including changes in signal to the somatotrophs from growth hormone releasing hormone, somatostatin
and other factors such as body composition, exercise, diet and sleep.
Occasional instances of sarcomatous transformation of fibrous dysplastic bones have been reported with radiation therapy (10,11), but radiotherapy may be an option for treatment of acromegaly in patients who have MAS when surgery is impossible and somatostatin
analog therapy is ineffective (12).
alpha]-Cells secrete glucagon in response to low blood glucose, glucagon stimulates liver to release glucose through glycogenolys is and gluconeogenesis and it also stimulates adipose tissue to release fatty acids through lipolysis; [beta]-cells produce insulin that stimulate muscle, liver and adipose cells to store glucose for later use by synthesizing glycogen, protein and fats (Figure 1), [delta]-cells secrete somatostatin
that inhibits insulin and glucagon release from their islet cells [10, 11].
The EO significantly increased the levels of motilin (MTL) and gastrin (GAS) and decreased the levels of somatostatin
(SS) and CRF.
