objective(s): as heat, pain is one of the most common clinical symptoms. generally, calcitonin (ct) is prescribed as an analgesic agent for the treatment of pain, especially for the pain caused by osteoporosis or primary and metastatic bone tumor. however, the detailed mechanism remains unknown.materials and methods: in this study, chronic constriction injury (cci) rat model was created, and ho...
Background: Amylin and Salmon Calcitonin belong to the calcitonin family of peptides and have high affinity binding sites in the rat spinal cord. The aim of this study was to characterize receptors for Amylin and Salmon Calcitonin functionally in the spinal cord of rats. We assessed the expression of c-Fos in response to intraplantar formalin in the lumbar regions of the spinal cord in consciou...
Background: Thyroid carcinoma is the most common endocrine malignancy and approximately accounts 2% of all cancer cases. Medullary thyroid cancer (MTC) is an endocrine tumor with differentiation of Parafollicular or C-cells and is categorized into hereditary or sporadic types. Medullary thyroid carcinoma approximately accounts for 5-10% of all thyroid carcinoma. Germ-line and somatic mutations ...
background: amylin and salmon calcitonin belong to the calcitonin family of peptides and have high affinity binding sites in the rat spinal cord. the aim of this study was to characterize receptors for amylin and salmon calcitonin functionally in the spinal cord of rats. we assessed the expression of c-fos in response to intraplantar formalin in the lumbar regions of the spinal cord in consciou...
Background and purpose: Osteoporosis is a general skeletal disease characterized by decreased bone mass over the years, bone fractures, decreased bone strength, and consequently increased bone fragility and fracture susceptibility. There is paucity of information about the effect of calcitonin on osteoporosis in Iran. The current study aimed at investigating the relationship between serum calci...
introduction : osteon® is an alloplastic material containing 70% hydroxyapatite and 30% β-tcp. calcitonin, a hormone produced by the thyroid gland, not only prevents bone resorption by reducing both the number and the activity of osteoclasts, but also stimulates bone formation. considering the favorable effects of calcitonin on bone formation, we hypothesized that the addition of calcitonin to ...
Calcitonin-secreting neuroendocrine neoplasms of the lung are rare, with few cases reported in literature. Differentiating between medullary thyroid carcinoma and an ectopic source calcitonin secretion can represent a complex diagnostic conundrum for managing physicians, unnecessary thyroidectomy This manuscript reports case hypercalcitonaemia from metastatic neoplasm concurrent pathology summa...
Background: Various therapeutic options such as calcitonin have been suggested for patients with low bone density, despite uncertain efficacy in most patients. C-telopeptide of type I collagen (CTX) is a new bone marker used for the assessment of bone resorption. The aim of this study was to evaluate the therapeutic effects of nasal spray calcitonin in women with osteopenia via serum CTX and ot...
Medullary thyroid cancer is a rare neuroendocrine tumor with aggressive behavior and an uncertain prognosis. Calcitonin the associated marker; however, tumors of lung or intestine can also present high values. We report case 53-year-old patient presenting dry cough for 3 years. Computed tomography (CT) showed 58-mm expansive lesion in right anterior mediastinum cervical ultrasound informed 9-mm...
Calcitonin gene-related peptide, a product of the calcitonin gene, is a potent vasodilator neuropeptide. We have demonstrated that dietary calcium deficiency decreased the neuronal (laminae I/II of the dorsal horn of the spinal cord) content of immunoreactive calcitonin gene-related peptide in the normal rat. Neuronal calcitonin gene-related peptide levels are also reduced in the spontaneously ...
