Book excerpt: Excerpt from The Journal of Immunology, Vol. 4 Many attempts have been made to devise a simple and accurate laboratory method for determining the presence of toxic and antitoxic substances in the blood of persons suffering from acute infections of various kinds and in the blood of normal individuals. Several methods adapted for the study of certain toxins have resulted. Many of these in the hands of most workers have been difficult to manipulate. Others have failed to give the qualitative and quantitative data necessary. It has been evident since the beginning of the study of toxins and antitoxins that their presence or absence must be determined by testing their effect upon animal tissues. Other and more accurate methods will probably not be devised until the chemical and physical properties of these substances are better understood. For a long time it has seemed apparent that the tissue culture method might aid very materially in making such determinations. Stimulated by the urgent need of a more careful study of many of the cases of diphtheria and other infections as they have been seen in the hospital and as they are reported from army camps we undertook recently to apply the method in this direction. As is well known the tissue cells of many animals grow readily not only in their own plasma but also in drops of plasma of many other animals.
