ABSTRACT
BACKGROUND:
Diabetes Mellitus (DM), a metabolic disease characterized by the increased blood glucose level, insulin deficiency or ineffectiveness, may cause structural and functional disorders in the brain. l-Theanine (LTN) has the relaxing, psychoactive, antidepressant, anti-inflammatory and antinecrotic properties, and regulates the functions of hippocampus (HP) in brain. In the present study, the aim was to identify the effects LTN on the levels of BDNF, insulin and adipocytokines (TNF-α, leptin, adiponectin and resistin) in both HP and serum of diabetic rats.METHODS:
32 male Wistar rats were divided into four groups (n = 8/group) Control, LTN, DM and DM + LTN. Diabetes was induced by by nicotinamide/streptozotocin. 200 mg/kg/day LTN treatment was applied for 28 days. The serum and hippocampal levels of the parameters were determined by using commercial ELISA kits. Additionally, HP tissues examined histopathologically.RESULTS:
LTN treatment significantly decreased leptin and adiponectin levels in HP tissues in diabetic rats (p < 0.05). Although it decreased the insulin level in both serum and HP, this was not statistically significant. No significant effect on other parameters was observed (p > 0.05). In histopathological analysis, although the damage was reduced by LTN in all sections of HP, this change was significant mainly in CA3 region (p < 0.05).CONCLUSION:
It was concluded that LTN has the ability to reduce hippocampal degeneration and modulates adipocytokines in diabetic rats.Palabras clave
