Biotesting of a burn toxin on mice with reticuloendothelial system block

: Experiments on mice with reticuloendothelial system blockade were made to assay the toxic properties of the preparations obtained from the skin of burn and normal rats. As regards the activity level the preparations can be classified with either highly toxic or little toxic. Analysis of the dose-response dependence indicates that toxicity of the extracts is accounted for by at least two different toxins.
