title: [The methods and clinico-diagnostic importance of a study of the periodic secretory activity of the gastroduodenal area].
abstract: The paper presents the results of examination of 73 subjects (51 males and 22 females) aged 20-45 on a diagnostic unit able to collect discrete portions of duodenal and gastric contents along with registration of antroduodenal motor activity. The dynamics of intradigestive secretion and motility gave evidence for identification of reference points and documentation of phases and stages of periodic secretory cycle. The secretory indices were studied with allowances for secretory periodicity. The signs were defined indicative of certain types of secretory disorders in disease.
