Effect of Intranasal Administration of Anti-Glutamate Antibodies after Stress Exposure on the Stress Response

We studied the dose-dependent effect of antibodies to glutamate on the stress response in C57Bl/6 mice. The antibodies were administered immediately after stress exposure. Intranasal administration of antibodies to glutamate in doses of 150 and 250 μg/kg immediately after stress exposure was shown to reduce the stress response under conditions of combined restraint stress. This effect was most pronounced after treatment with antibodies in a dose of 250 μg/kg: we revealed a decrease in the number and severity of erosive and ulcerative lesions in the gastric mucosa, i.e. anti-glutamate antibodies have a protective effect.
