In volume I (Subtitled: Biochemical, methodological and functional aspects), the purification and structure/function relationships of VIII and vWf are extensively reviewed with the relevance of advances in these areas to improved methodology and biotechnology. Emphasis is on the importance of improved interactions with plasmatic and cellular components. The issues of plasma procurement and advances in the production of therapeutic products illustrate application. An update of progress in the clinical aspects of VIII and vWf deficiency states is presented in Volume II (Subtitled: Clinical aspects of deficiency states; 6829-4). The critical issues of scientific advancement and achievement are shown to result in improved patient diagnosis and care. Annotation copyrighted by Book News, Inc., Portland, OR
