    Amex's Biotechnology Index

    NEW YORK -- The American Stock Exchange said it replaced Immunex
 Corp. with Immune Response Corp. in its index of 15 leading
 biotechnology stocks known as the biotechnology index.
    The decision to replace Immunex was based on a majority of the
 stock now being held by Lederle Oncology Corp., a unit of American
 Cyanamid Co., as a result of a recent merger between Immunex and
 Lederle, the exchange said.  Immune Response, Carlsbad, Calif., makes
 products for use in the treatment of HIV infection.  Immunex is a
 Seattle immunological research and development company.
