PREFACE 
This is the nineteenth in a series constituting a "public record" of activities in regard to the 
National Institutes of Health (NIH) Guidelines for recombinant DNA research. 
The first eighteen volumes cover events from February 1975 through December 1993. This 
nineteenth volume covers events from January 1994 through August 1994. 
Starting from Volume 14, human gene transfer/therapy protocols that have been approved 
by the NIH Recombinant DNA Advisory Committee, are collected. Documents of each 
human study include the clinical protocol, the Informed Consent document describing the 
study in a nontechnical language, both scientific and nontechnical abstracts, and curriculum 
vitae of the principal investigators. 
Volumes 1 through 5 in this series and the Environmental Impact Statement may be 
purchased from the Superintendent of Documents, U.S. Government Printing Office (GPO),
