pubmed-article:2422441 | pubmed:abstractText | We investigated the impact of chronically administered synthetic cyclic somatostatin-14 on the nude mouse. Four groups of seven animals each received intraperitoneal injections twice daily for 14 days with diluent or 5, 50, or 500 mcg/kg somatostatin in hydrolyzed gelatin. Overall health and body weight were unaffected by this treatment. Among the seven organs examined at necropsy, kidney alone showed a dose-related gain in weight with increasing somatostatin dose. Renal RNA content also increased in response to somatostatin treatment, but liver DNA content and small bowel DNA content and protein content decreased. This work indicates that somatostatin affects metabolism of gastrointestinal tissues and provides evidence that renal growth can be regulated by somatostatin. Whether similar effects occur at a physiological somatostatin level is unknown, but the current findings suggest new therapeutic possibilities for this hormone. | lld:pubmed |
