Effect of sub-chronic ferrous sulfate treatment on motor skills, hematological and biochemical parameters in rats.

This study investigated the effects of ferrous sulfate (FeSO4) on motor skills, hematological and biochemical parameters in rats. Adult rats were treated with dose of iron (280 mg/L, ) for 15 consecutive days in drinking water. No significant difference was noticed for the motor skills in the stationary beam ( = 0.23) and suspended string tests ( = 0.48) between control and iron-treated rats. However, iron-treated rats showed a significant increase in white blood cells count ( = 0.01), mean corpuscular volume values ( = 0.02) and decrease in frequency of peristaltic contractions of the fragment of the intestine (in vitro) compared to control rats ( = 0.01). No significant difference in plasma iron level ( = 0.89) and transferrin amount were observed after iron treatment ( = 0.65). The findings indicate that iron treatment at 280 mg/L, for 15 consecutive days in adult rats induced increase of hematological parameters (sign of a potential inflammation), but not motor skills deficit.
