Somatrem (Protropin)
derivative of GH, used to treat GH deficiency
what 4 types of cells does the islets of lanagerhans contain?
islets of langerhans contain several types of cells:
alpha: secrete glucagon, stimulates production of glucose
in the liver
beta: secrete insulin, number of actions including uptake
of glucose by various tissues
delta: secrete somatostatin, reduce absorption of food
gamma: peptide with unknown function
