Title: Method for providing enlarged prints of color transparencies and negatives
Inventor: KOBEL JOHN O
IPC: G03B27/56
Filed: 1990-09-06
Abstract: ABSTRACT OF THE DISCLOSURE            Disclosed is a system for producing a full color en-larged  reproduction  of  a  color  transparency  or negative (3) on a photographic paper. The system makes use of a conti-nuous tone scanner (1) having a given contrast range to produce enlarged color separation negatives of the original transpa-rency or negative (3) on a continuous tone photographic film (5). Prior to producing these enlarged color separation nega-tives, the continuous tone scanner (1) is adjusted to conden-sate its contrast range to accommodate the photographic paper. The color separation negatives that are so obtained may be used,  after  development,  for  producing  the  requested  full color enlarged reproduction on the photographic paper,  using a three color printing system (9) to do so. The color print that  is  so  obtained has  an  excellent  definition  and  color reproduction.          - Figure 1 -

Title: Chimeric antibody against drug-resistant cancers and process for production thereof
Inventor: TSURUO TAKASHI
IPC: C07K16/00
Filed: 1990-09-19
Abstract: Abstract A monoclonal antibody, MRK16, reactive to the multidrug transporter P-glycoprotein, has been generated in an effort to devise an effective treatment for human drug-resistant cancers.          The monoclonal antibody inhibited the growth of human drug-resistant tumor cells in a xenograft model, suggesting its potential usefulness in the immunotherapy of drug-resistant cancers.  A recombinant chimeric antibody has been developed by joining the antigen-recognizing variable regions of MRK16 to the constant regions of human antibodies.  When human effector cells were used, the chimeric antibody MH162 was more effective in killing drug-resistant tumor cells than the all-mouse monoclonal MRK16.  The chimeric antibody against the multidrug transporter P-glycoprotein will be a useful agent in immunotherapy of human drug-resistant cancers.
