although peak and integrated serum gastrin concentrations were significantly greater in patients ( 450 +/- se 109 pg/ml ; 113 +/- 2.9x10 ( -3 ) pg/ml/min ) compared with control subjects ( 174 +/- 98 pg/ml ; 6.1 +/- 2.0x10 ( -3 ) pg/ml/min p less than 0.05 ) , no concomitant increase in acid secretion was shown either during intragastric titration or in response to pentagastrin .
