Objective: Ghrelin is an orexigenic hormone mainly released from the stomachs of rats and takes a significant part in the
development of newborn rats. Ghrelin has been shown to possess antioxidant, anti-apoptotic, and anti-inflammatory
properties. In this study, we aimed to examine microscopical and biochemical parameters in the kidney of newborn nontreated diabetic and ghrelin-treated diabetic rats.
Materials and Methods: Wistar-type newborn rats were divided into four groups. First group: control rats given physiological
saline for four weeks; second group: control animals given ghrelin from the third day to the fourth week; third group: diabetic
rats given streptozotocin (STZ) on the second day after birth as a single dose; fourth group: diabetic rats given ghrelin from
the third day to the fourth week.
Results: There was no microscopic difference between the kidney tissues of non-treated diabetic and ghrelin-treated diabetic
rats. Lipid peroxidation levels decreased, while superoxide dismutase, catalase activities, and glutathione levels increased in
the diabetic group given ghrelin. Serum urea, uric acid, creatinine levels, myeloperoxidase, and xanthine oxidase activities
decreased in diabetic rats treated with ghrelin.
Conclusion: It can be said that the ghrelin given exogenously has a protective effect in some degree on renal complications
in newborn diabetic rats.
