Abstract
Background: Animal models of stress are a good for studying the stress induced disorders. The present study investigated the effect of immobilization and surgery stress on plasma ghrelin concentration, food intake and body weight.
Materials and Methods: This was an experimental study. 40 adult female rats were divided into 4 groups. Control group: no stress. In sham Group anesthetic and antibiotic drugs were administered. Surgery group rats were subjected surgery stress. Immobilization group rats were subjected to immobilization stress for 7 days. On the seventh day, blood samples were obtained directly from the animal’s heart. Serum Ghrelin concentrations were measured by ELISA. The changes in body weight during 7 days were recorded. Food intake was measured daily.
Results: Surgical stress had no significant effect on serum ghrelin concentrations but immobilization stress caused a significant increase in blood levels of ghrelin. Surgery and immobilization stress had no significant effect on body weight. Immobilization stress caused a significant increase in food intake.
Conclusion: The effect of Stress on serum ghrelin level and food intake depends on the kind of stress.
