Abstract:
Objective(s) Since diabetes mellitus is accompanied by cognitive impairment in diabetic patient and animal models and since lipids play important roles in neuronal membrane composition, structure and function; we intended to evaluate the effect of dietary butter oil on passive avoidance memory of streptoztosin (STZ)-induced diabetic rats in this study. Materials and Methods Thirty six adult male rats were randomly allocated to four equal groups: normal (N) and diabetic control (D) groups[R۱] with free access to regular rat diet; but the diet of normal butter oil (NB) and diabetic butter oil (DB) groups was supplemented with ۱۰% butter oil. Diabetes in D and DB groups was induced by intravenous (i.v.) injection of ۵۰ mg/kg.bw of STZ. Passive avoidance memory and cholesterol of brain and hippocampal tissues has been measured six weeks after diabetes confirmation. Results Diabetes, especially in diabetic butter oil group decreased the abilities of learning and memory. The level of cholesterol in hippocampus was higher in NB (P< ۰.۰۵) and DB (P< ۰.۰۱) groups. Conclusion We suggest consumption of butter oil may worsen cognitive impairment of diabetic animal. This may be related to the higher elevation of cholesterol in the hippocampus of diabetic animals.
