it is proposed that the prime site of somatostatin action was in the abomasal to caecal region , where somatostatin-secreting d cells are found in greatest concentration , that effects observed in the large intestine and rumen may represent secondary compensatory mechanisms and that the effects observed were due to direct action of somatostatin and were not mediated by other gi hormones .
