  • Title: Somatostatin-induced inhibition of insulin secretion by isolated pancreatic rat islets prepared by micro-dissection or collagenase digestion.
    Author: Hahn HJ, Gottschling HD.
    Journal: Diabete Metab; 1976 Sep; 2(3):107-11. PubMed ID: 188697.
    Abstract:
    The effect of somatostatin on insulin secretion in response to a variety of stimuli was investigated in micro-dissected as well as collagenase isolated pancreatic rat islets. Somatostatin inhibited insulin secretion in both islet preparations in the presence of different initiators, but failed to affect the hormone output induced by theophylline, 1-methyl-3-isobutylxanthin (IBMX) or p-chloromercuriphenylsulfonic acid (CMBS). The inhibitory action was associated with decreased glucose metabolism by islets (measured as conversion of U-14C-glucose to 14CO2).
