Objective:To study the effects of Haierful Oral Liquid on the prevention of liver and kidney in mice with lead poisoned.Methods:To make the animal model of the lead mice,and then treated them with Haierful Oral Liquid,determined the biochemical criterions of lead mice and tissue-aliced mice liver and kidney,then observed their pathologic change under the light microscope.Results:The damage was much serious to the liver and kidney of lead mice than those were treated by Haierfu Oral Liquid.Conclusions:Haierful Oral Liquid had significant effects on the accelerating lead excretion,improved the Hb of blood and its antioxidant function,thus lightening the substance damage of the liver and kidney of lead mice.
