A study was made of changes of the content of hormones (gastrin, insulin, glucagon, triodonthyronine, thyroxine, thyrotrophin, somatotrophin, adrenocorticotrophin and hydrocortisone) under the influence of standard food load in 166 patients with GIT diseases (gastric ulcer, duodenal ulcer, chronic anacid gastritis and chronic enteritis). Forty-three healthy persons entered the control group. Hormones were determined in the peripheral blood by radioimmunoassay. Taking food in healthy persons was shown to cause the stimulation of the secretion of most hormones. To elucidate the mechanisms of hormonal shifts after food load, hormones were also studied after per os intake of solutions with different pH. Disorders of postprandial reactions of the endocrine system which were specific for these nosological forms, were revealed in GIT diseases. The results of the study are of interest in view of new approaches to functional interrelationships of the GIT with endocrine glands.

The present study was conducted to clarify the influence of feeding habits on regional distribution and relative frequency of endocrine cells secreting cholecystokinin (CCK), gastrin (GAS), serotonin (5-HT) and enteroglucagon (GLUC) in the nectarivorous Anoura geoffroyi and Glossophaga soricina and the sanguivorous Desmodus rotundus bats of the Phyllostomidae family, by specific immunohistochemical methods. The regional distribution and frequency of the different types of endocrine cells varied according to their location in the GIT. 5-HT immunoreactive cells (IR), detected throughout the GIT of three bats, were the most predominant gastrointestinal endocrine cells. GAS-IR cells in A. geoffroyi were found at the base of the pyloric gland, while in G. soricina they could also be observed in the middle to basal portions of the gland. GLUC-IR cells were located in the fundic region of A. geoffroyi, G. soricina and D. rotundus. These endocrine cells were more abundant in the sanguivorous bat. In nectarivorous bats were compared to sanguivorous bat, which differ in dietary habits, difference in the distribution and relative frequency of gut endocrine cells would be predicted. The absence of some, and decrease in frequency of other, gastrointestinal endocrine cells may reflect, in part, its interspecies differences or dietary habits.
