[Determination of the optimal proportions as regards toxicity of AET, ATP and serotonin used in combination].

In experiments on mice, a study was made of the quantitative dependence of toxicity of AET, ATP and serotonin applied in combinations. The toxicity decreased when ATP was combined with AET and increased when ATP of AET were combined with serotonin. The toxicity of a combination of all three substances was reduced by introducing high doses of ATP.
