Experiments with guinea pigs are described which show that under special experimental conditions the intraperitoneal injection of conjugates made with homologous erythrocyte stromata leads to typical skin sensitization of the contact type towards the respective simple chemicals, namely picryl chloride or 2,4-dinitrofluorobenzene. Therefore such sensitivity can be brought about not only by low molecular chemical compounds but by a material which must be regarded as a typical antigen.

A method has been described by which sensitization to a simple chemical, picryl chloride (2:4:6 trinitrochlorobenzene), can be satisfactorily attained by means of intraperitoneal injection of the compound when killed tubercle bacilli suspended in paraffin oil were used as adjuvant. Sensitivity of the contact dermatitis type results therefrom. It follows that although skin sensitization of this type is most easily obtained by dermal application this route of administration is no necessary condition for such sensitivity.

Guinea pigs fed picryl chloride to induce specific immunologic unresponsiveness cleared small amounts of venously infused antipicryl antibody at a rate equal to that of normal guinea pigs. Catabolism of passively administered picryl-specific antibody did not alter the unresponsive state of picryl chloride-fed guinea pigs or the responsive state of normal guinea pigs. Lymphoid cells of picryl chloride immunized guinea pigs produced equal amounts of picryl-specific antibody in picryl chloride-fed and normal animals. Allergen-fed guinea pigs remained unresponsive to attempted sensitization with the allergen in excess of 10 months after the final feeding, though some became feebly sensitive between 9 and 11 months. Second attempts to make unresponsive animals hypersensitive were unsuccessful. White blood cells of guinea pigs unresponsive to picryl chloride were unable to transfer delayed-type hypersensitivity for picryl chloride to normal recipients yet readily transferred tuberculin hypersensitivity.

It has been shown that by the cutaneous administration of simple chemical compounds in small quantities—2:4:6 trinitrochlorobenzene (picryl chloride) and 2:4 dinitrochlorobenzene, the latter a typical incitant of contact dermatitis in man—it is possible to induce true anaphylactic sensitization in guinea pigs, demonstrable by the intravenous injection of protein conjugates and by the Dale technique, using isolated uterine horns. This furnishes strong evidence for the formation of antigenic conjugates following application of substances of simple chemical constitution. Since the anaphylactic state is induced by the same method of administration that gives rise to cutaneous sensitivity, the assumption would appear justified, when one takes into account the chemical properties of the inciting substances, that the formation of conjugated antigens offers an explanation for the skin effects also. In the experiments with picryl chloride, anaphylactic antibodies, and occasionally precipitins, have been demonstrated. The differences between the cutaneous and anaphylactic types of sensitivity are discussed.

It has proved possible to set up lines of guinea pigs of significantly different susceptibilities towards a compound of simple structure, namely 2:4 dinitrochlorobenzene. This provides direct evidence that the type of sensitization under discussion is influenced by heredity.

Experiments on the sensitization of guinea pigs with simple chemical compounds are described. Positive effects were obtained by the administration of small quantities, namely fractions of milligrams, with 1:2:4 chlorodinitrobenzene, p-nitrosodimethylaniline, 1:2:4 trinitrobenzene, picryl chloride, four dichlorodinitrobenzenes, and a number of other aromatic compounds. Several substances chemically similar to those enumerated gave negative results. The first named compound is known to produce hypersensitiveness in human beings, a large number of cases having been observed in factory workers. The mechanism of these effects is discussed.

Evidence is presented to show that guinea pigs actively sensitized to simple chemical compounds form serum antibodies capable of sensitizing the skin of normal guinea pigs. Skin sites prepared as for the Prausnitz-Küstner test develop immediate-type ("evanescent") reactions with erythema and edema, upon subsequent injection of the corresponding simple compounds or protein conjugates thereof, and give effects resembling transferred reaginic reactions as seen in human beings. The antibodies were obtainable after sensitization by acyl chlorides, acid anhydrides, and also substances of lesser reactivity, picryl chloride and 2:4 dinitrochlorobenzene, which are human allergens. Observations are reported on the specificity of the antibodies and on various details of the reaction. Like effects result when antiprotein immune sera and their corresponding antigens are employed for the test, making it highly probable that the antibodies secured after sensitization to drugs result from immunization by conjugates formed in vivo. The sera obtained after sensitization with simple chemical compounds readily confer passive anaphylaxis, and their capacity for sensitizing the skin declines gradually with progressive heating. It was observed that following a reaction of substantial degree in guinea pig skin the area involved does not fully recover for some days its capacity to react, the effect being a manifestation, it would seem, of what has been termed "non-specific antianaphylaxis."

Experiments are described which show that with a given treatment guinea pigs can be sensitized to arsphenamine, so that a considerable percentage die in anaphylactic shock on intravenous administration of the substance.

With the view of making new types of chemicals accessible for investigations on drug hypersensitiveness, methods have been devised for sensitizing animals with diazomethane and mustard oil, two non-aromatic compounds. Guinea pigs have been sensitized to diazomethane, a substance of high reactivity and known to cause severe allergic effects in man. With the second substance, allylisothiocyanate, likewise capable of forming conjugates with substances in the animal body, sensitization effects have been obtained in man and in hogs. Sensitization in human beings was successful with one out of six individuals treated. The observations indicate species and individual differences as regards the ability to become sensitized to various chemical compounds.
