    摘要: The complete coding sequences and amino acid sequences for both canine and human 32K alveolar surfactant proteins (ASP) are disclosed; clones encoding variants of the SP-18 and SP-5 forms of human protein are disclosed. Methods and vectors for obtaining these proteins in recombinant form are also described. An improved method for purification of the 32K protein takes advantage of its carbohydrate affinity. Pharmaceutical compositions in the treatment of respiratory deficiency syndrome use the 10K proteins with or without the 32K form. Synthetic peptides based on the human SP-5 protein are provided as well, which peptides show significant ASP activity.

    摘要: A method and apparatus for draw forming a metal sheet over a male form to produce a three-dimensional shape. A sheet of metal is clamped between upper and lower draw plates positioned above the male form. The upper plate has an edge conforming to the male form shape. The plates and sheet are moved downwardly over the form with the edge of the upper plate firmly pressing the sheet against the form. The clamping pressure between the draw plates allows suitable slippage as drawing proceeds to produce a drawn shape of intended thickness. The drawn shape has a configuration conforming to the outer surface of the male form and has an outer surface of improved uniformity and appearance due to the wiping action of the upper plate edge.
