    Description / Table of Contents: Zusammenfassung Wir haben an 160 Meerschweinchen epicutane Sensibilisierungsversuche mit parasubstituierten Benzolderivaten in 4 Konzentrationsstufen durchgeführt und die Beurteilung der Testreaktionen nach makroskopischen und histologischen Kriterien vorgenommen. Den mit jeder Substanz an 32 Tieren gewonnenen Ergebnissen ist zu entnehmen, daß Sensibilisierungen eingetreten sind mit p-Aminodiphenylamin in etwa 50%, mit p-Toluylendiamin in etwa 25%, mit p-Phenyldiamin in 62% (bei 1- und 2%iger Konzentration), mit p-Aminoazotoluol in 37% (mit 5%iger Konzentration), mit p-Aminobenzoesäure in keinem Fall. Aus dem Vergleich der Sensibilisierungsquoten ist zu schließen, daß p-Aminodiphenylamin und p-Phenylendiamin als starke Sensibilisatoren anzusehen sind, p-Aminoazotoluol und p-Toluylendiamin einen geringeren Effekt aufwiesen und p-Aminobenzoesäure unwirksam blieb.
    Notes: Summary Skin tests with derivates of para-substituted benzene were carried out at 4 different concentrations on a total of 160 guinea pigs. Results were evaluated macroscopically and histologically. Each substance was tested on 32 animals. Sensitization was obtained with p-aminodiphenylamine in about 50%, with p-toluylenediamine in about 25%, with 1% and 2% p-phenylenediamine in 62%, with 5% p-aminoazotoluene in 37%, whereas no sensitization was observed with p-aminobenzoic acid. Thus, p-aminodiphenylamine, p-toluylenediamine and p-phenylenediamine must be regarded as highly sensitizing agents, whereas p-aminoazotoluene and p-aminobenzoic acid seem to be less effective respectively non sensitizing.

    Notes: Abstract Sepsis, the systemic response (specific and non-specific) of the body to an infection, is an increasing clinical problem. During the last 30 years, nearly 50 clinical trials involving more than 10,000 patients have failed to demonstrate improvement of patients' outcome with different “anti-mediator” strategies. The wrong conceptional approaches to interact with the complex mediator network and flaws in study design and conduct are the main reasons for this disappointing situation. We learned, however, that the systemic host response is more than persistent uncontrolled inflammation; it is also a stimulation of the counter regulatory network. Although it is important to analyse the complex picture, we have now reached a point where more sophisticated strategies for describing complexity and novel attempts for synthesis are needed. Along this line, improved study designs (decrease of “signal-to-noise ratio”) are mandatory. In addition, secondary preventive strategies are emphasised.
