Özet

Objective: Despite the fact that the negative effects of sulphite on learning and memory have been reported in the literature, the information on molecular mechanisms is insufficient. In our study, the effects of different doses of sulfite, which is known to have neurotoxic effects, on learning and memory were evaluated by behavioral experiments. The role of ACh in the effects of sulfite on learning and memory, and its possible mediating mechanisms were investigated.

Method: 3 months old male albino Wistar rats were divided into three groups. Distilled water was given to control group, sodium metabisulphite at dose of 100 mg/kg and 260 mg/kg was given to the sulphite groups for 35 days by gavage. Behavioral changes were evaluated using the Morris Water Maze, Open Field and New Object Recognition test. After behavioral experiments were taken, hippocampi were removed under anesthetized. ACh levels, AChE and ChAT enzyme activities were measured in hippocampus tissues.

Results: It has been observed that the total distance and average velocity performed in the Open Field test and Morris Water Maze prop trial were increased, the discrimination index in the New Object Recognition test decreased in the sulphite applied groups. The amount of plasma S-sulfonate and ACh in the sulphite applied groups were found to be increased. While AChE activity decreased significantly in the sulphite applied groups, ChAT activity increased significantly.

Conclusion: In conclusion, it has been shown that sulphite intake in adults impairs learning and spatial memory, and this impairment may be mediated by the cholinergic signal pathway.
