Evaluates the neurobehavioral effects were resulted from dosing of sodium nitrate in mice. Mice were divided into 5 equal groups, the first group; control group was fed from concentrated feed (Barley, Wheat, Soybeans, Corn and Bran), the second group was added 0.2% sodium nitrate and the third group was added 0.2% sodium nitrate with 0.4% ascorbic acid, fourth group was added sodium nitrate 0.4% alone and the fifth group was added 0.4% sodium nitrate with 0.8% of ascorbic acid for five weeks. Sodium nitrate did not produce clear signs of toxicity, but a significant decrease in motor activity and standing on the hind legs (rearing) was observed in the open-field activity test, where the lowest level was reached in the fourth week of treatment, and these declines returned gradually to reach the control group level values at the end of the study period. Sodium nitrate was significantly delayed at the time of the negative geotaxis test at a 45 ° while returning to the control level in the fifth week, also showed that there was a significant increase in body weight compared to pre-treatment value. In this study 0.8% of ascorbic acid with 0.4% sodium nitrate in group 5 showed differed significantly with 0.4% sodium nitrate only in group 4, that means the ascorbic acid give a beneficial result when used for remedy of nitrate toxicity.
