ABSTRACT

Objective: To identify the minimal dose of the somatostatin analogue SMS 201 995 with effect on intestinal secretion and absorption and on glycemia.
Setting: School of Medicine.
Design: Experimental study in laboratory animals, prospective, with control group.
Statistical analysis: The mean, variance, and standard deviation of each variable were obtained. Student’s t test was used.
Material and methods: A modified Tryri Vela loop was used in five mongrel dogs, the 6-hour intestinal liquid was collected every 24 hours during 10 days. Three study groups were formed. I. Basal. II. Subcutaneous administration of 1 µg/kg of the analogue, and III. Subcutaneous administration of 5 µg/kg of the analogue. The volume, protein and electrolyte contents were measured in the collected intestinal liquid; from the 150 samples, 44 were discarded for the animal had partially ripped the ileostomy sac and collection was incomplete. Glycemia was determined before and 30 min after analogue administration.
Results: The loss of volume and protein content decreased more than 50% in groups II and III (p ‹ 0.01), without difference between these two groups (p › 0.05). Decrease in electrolyte loss was smaller; the difference between group I and groups II and III was significant (p ‹ 0.05), but not between the two latter groups (p › 0.05). Glycemia increased more than 25% in groups II and III (p ‹ 0.05); no difference was observed between groups II and III (p › 0.05).
Conclusion: The SMS 201 995 analogue reduced the intestinal loss of water, proteins, and electrolytes, besides producing hyperglycemia. There was no difference between the 1 and 5 µg/kg dose of the analogue.


Key words: Somatostatin, analogues, intestinal secretion and absorption, glucose.
