Abstract

Diabetes mellitus is accompanied with disturbances in learning, memory, and cognitive skills in the humans and experimental animals. Due to the anti-diabetic and antioxidant activity of PELARGONIDIN (PG), this research study was conducted to evaluate the efficacy of chronic oral PG on alleviating LEARNING AND MEMORY disturbance in streptozotocin-diabetic rats. Male Wistar rats were divided into control, diabetic, PG-treated control and PG (single-and/or multipledose) - treated diabetic groups. PG was administered p.o. once at a dose of 10 mg/kg and/or multiple doses on alternate days for 8 weeks. For induction of diabetes, streptozotocin (STZ) was injected IP in a single dose of 60 mg/kg. For the evaluation of LEARNING AND MEMORY, initial latency (IL) and step-through latency (STL) were determined at the end of study using a passive avoidance test. Meanwhile, SPATIAL MEMORY was assessed in a Y-maze task. It was found that the alternation score of the DIABETIC RATs was lower than the control (p<0.05) and that single dose PG-treated DIABETIC RATs (p<0.05) showed a higher alternation score in comparison with the diabetic group. Regarding initial latency, there was no significant difference among the groups. In addition, diabetic and single-dose PG-treated DIABETIC RATs developed a significant impairment in retention and recall in the passive avoidance test (p<0.01), as was evident by a lower STL. Furthermore, the retention and recall of multiple-dose PG-treated DIABETIC RATs was significantly higher in comparison with DIABETIC RATs (p<0.05). Therefore, it can be concluded that single-dose oral PG may attenuate SPATIAL MEMORY in the Y maze paradigm and multipledose chronic PG could improve retention and recall capability in the passive avoidance test in STZ-diabetic rats.
