Calcitonin is a polypeptide hormone secreted by the parafollicular cells (C cells) of the thyroid gland in mammals and by the ultimobranchial body in non - mammalian vertebrates. The product with the CAS number 9007 - 12 - 9 is of high quality and available at the best price. This calcitonin is typically a white or off - white lyophilized powder. It is soluble in water and has a molecular weight that varies depending on its specific source and structure. The purity of our calcitonin product is carefully controlled to meet high - end research and medical requirements. The specific activity of the product is well - defined, ensuring its effectiveness in various applications.
Calcitonin has several important uses in both medical and research fields. In medicine, it is mainly used for the treatment of osteoporosis. By inhibiting osteoclast activity, calcitonin helps to reduce bone resorption, thereby increasing bone density and reducing the risk of fractures. It is also used in the treatment of Paget's disease, a disorder that causes abnormal bone remodeling. Calcitonin can relieve pain associated with Paget's disease and slow down the progression of the disease. Additionally, it can be used to treat hypercalcemia, which is a condition characterized by abnormally high levels of calcium in the blood. In research, calcitonin is used to study bone metabolism, the regulation of calcium homeostasis, and the function of the endocrine system.
For medical use, calcitonin is usually administered by injection or nasal spray. When using the injectable form, it should be reconstituted with the appropriate diluent according to the instructions. The injection site should be clean and rotated regularly to avoid local irritation. The dosage is determined by the patient's condition, age, and other factors, and it is usually prescribed by a doctor. For the nasal spray, patients should follow the instructions on how to use the device properly to ensure the correct dosage is delivered. In research settings, the usage of calcitonin may vary depending on the specific experimental design. It can be added to cell cultures at a specific concentration to study its effects on cell behavior, or it can be administered to experimental animals to observe its physiological effects.
Case 1: Osteoporosis Treatment
A 65 - year - old female patient was diagnosed with osteoporosis. Her bone mineral density was significantly lower than the normal range for her age. The doctor prescribed calcitonin injections. After six months of treatment, the patient's bone pain was significantly reduced. A follow - up bone density test showed a slight increase in bone density. Over the next year of continuous treatment, the risk of fractures was significantly decreased, and the patient's quality of life improved.
Case 2: Paget's Disease
A 52 - year - old male patient with Paget's disease suffered from severe bone pain in his spine and legs. Calcitonin nasal spray was prescribed. Within a few weeks of starting the treatment, the patient reported a significant reduction in pain. After three months of treatment, the abnormal bone remodeling in the affected areas showed signs of improvement, as indicated by imaging studies.
Case 3: Research on Bone Cells
In a laboratory study, researchers added calcitonin to a culture of osteoclasts. They found that the activity of osteoclasts was inhibited, and the formation of resorption pits on the bone - like substrate was reduced. This study provided further evidence for the mechanism of action of calcitonin in bone metabolism.
