Angesichts des Ausbruchs der Corona-Pandemie erfährt Foucaults Konzept der Biopolitik eine verstärkte Aufmerksamkeit innerhalb der politisch- philosophischen Debatten. So lässt sich in Rückgriff auf Foucaults Analyse einer sich seit dem 17. Jh. durchsetzenden „Lebensmacht“ nicht nur zeigen, inwiefern Maßnahmen zum Schutz der Bevölkerung vor einem neuartigen Virus Leben erhalten. Foucaults Beschreibung des Rassismus liefert auch einen ersten Analyseansatz, um die differenzielle Bestimmung von schützenswertem Leben zu problematisieren. Gilt es darüber hinausgehend zu verstehen, durch und innerhalb welcher je spezifischen Rahmendispositive biopolitische Logiken operieren und wie es möglich wird, rassistischen Kalkülen zu widerstehen, stellen Judith Butlers und Donna Haraways Reflexionen über Körperlichkeit, Immunität und Vulnerabilität eine entscheidende Erweiterung dar. Der Beitrag geht der Frage nach, welche Implikationen biopolitische Strategien angesichts einer globalen Gesundheitskrise haben, und versucht davon ausgehend, eine andere Form der Politik zu denken, die auf eine wechselseitige Verbundenheit bzw. Interdependenz und die daraus resultierende Vulnerabilität als geteilte Bedingung allen (menschlichen) Lebens reflektiert. Eine solche Politik bezieht sich nicht auf „das Leben selbst“, sondern auf die ökologischen und sozialen Beziehungen, die ein lebbares Leben erst ermöglichen. Facing the outbreak of the corona pandemic, Foucaults concept of biopolitics is attracting increased attention within the political-philosophical debates. Foucaults concept on biopolitics provides a starting point to analyze power mechanisms that work within politics currently in place, which protect the population from the corona virus. Judith Butlers and Donna Haraways reflections on corporality, vulnerability and immunity offer a further and deeper understanding on how racist logics within biopolitical fields define certain lives worthy of protection and others not, as well as how politics opposing such hierarchies can look like. This paper focuses on the implications of biopolitical strategies, especially in times of a global health crisis. Furthermore, it focuses on the possibility of a politics that reflects on interdependency and vulnerability as a shared condition of all (human) life. Such a politics does not focus on “life itself” but on the ecological and social relations, which enable life. (VLID)5810440

The defence mechanisms of the human body against harmful influences from the environment are manifold. The aggressions on the integrity of the organism are physical, chemical, or biological in nature. In this paper the interactions of the commonly used cytotoxic drugs with various defence mechanisms are discussed. Impairment of these defence mechanisms by cytotoxic drugs results in a whole variety of clinical pictures, such as delayed wound healing, secondary malignant neoplasms or many different infectious diseases. These cytotoxic drug-induced diseases are summarized under the term IDDSS (Induced or Iatrogenic Defence Deficiency SyndromeS).

Provided that immunoreactivity exists against cancer cells, there are a number of biologically and medically relevant phases and processes such as old age, genetic defects, postradiologic and postchemotherapeutic metabolism, which can be accompanied or followed by short-term and persistent, partial or subtotal immune deficiency states, respectively. It will depend on several factors, which are difficult to elucidate heretofore, whether the tumour will bypass the concequences of immunogenecity, i.e. the stimulation of tumour immunity. Some of these factors are being studied in experimental and immunoclinical test systems. The critical representation of this paper ought to reinforce investigations into the essential parameters as well as the perpetuation of well planned randomized prospective studies on the basis of immunoclinical methods.

Since at least 350 million children on our earth suffer from severe caloric and especially protein deficiency it is of utmost importance to know its relation to host defense. In the first part of this paper the already known facts about nutrition and immune response are summarized. Especially the negative effects on the humoral and cellular immune mechanism are critically reviewed. Another chapter deals with the trophogenic immunity; especially the significance of secretory IgA of lactoferrin and lactoperoxydase is pointed out. Recent scientific work disclosed some anti-bacterial, anti-viral, and anti-mycotic properties of certain fatty acids.
