Monosodium glutamate
(
MSG
) is the most widely used additive in the food industry; however, some adverse effects of this additive, including functional, learning, and behavioral alterations, have been observed in experimental animals and humans. Studies have shown learning and memory impairment in adult animals exposed to
MSG
. However, studies relating exposure to
MSG
to acetylcholinesterase (AChE) and Na
+
, K
+
-ATPase activities and memory damage are still scarce in the literature. The aim of the present study was to assess the possible protective effects of selenofuranoside, an organoselenium compound, against the impairment of long-term memory, Na
+
, K
+
-ATPase and AChE activities, and oxidative stress after
MSG
exposure in rats.
MSG
(2g/kg) and/or selenofuranoside (5mg/kg) were administered orally to 5-week-old male Wistar rats for 10days. On the 10th day, after the administration of last dose of the drug(s), the rats were subjected to behavioral tests: the open-field test and step-down passive avoidance task (SDPA). The blood, liver, kidney, cortex, and hippocampus were removed to determine the oxidative stress parameters, such as the levels of reactive species, lipid peroxidation,
antioxidant enzyme
activities, and endogenous nonenzymatic antioxidant content. Furthermore, the cortex and hippocampus were used to determine the Na
+
, K
+
-ATPase and AChE activities. The results demonstrate that the administration of
MSG
led to long-term memory impairment, as shown in the SDPA task, and also hippocampal and cortical Na
+
, K
+
-ATPase inhibition. There were no alterations in the AChE activity and oxidative stress parameters. Treatment with selenofuranoside attenuated memory impairment associated with
MSG
exposure by improving the hippocampal Na
+
, K
+
-ATPase activity.
