Two general questions stood at the beginning of this PhD-thesis, namely: - What are the mechanisms which lead to the emergence and establishment of new technologies? - How can this process of technological change be influenced politically? In this sense, conceptual and theoretical interests were the early driving forces of the research work. This is also reflected in the considerable attention paid to the nature of technological change and political control. The result is an holistic per- spective which builds on inputs from different disciplines and aims at dynamic interpretation. This,...

The clinical and experimental effects of cytokines have been realized for a long time. The clinical effects of tumor necrosis factor were noted almost 100 years ago. The basic biological effects of interferons and the hemopoietic growth factors have been known for more than 20 years. Given the basis of modern molecular biotechniques, information concern- ing the mediators of cellular interactions is expanding almost exponentially. New principles in the regulation of cell growth, microenvironment, immune response, and malignancy are being discoverd right now. New therapeutic options are...
