BIOCHEMICAL WEAPONS AND HUMAN SUBJECTS RESEARCHThe threat of biological and chemical terrorism highlights a growing tension in research ethicsbetween respecting the interests of individuals and safeguarding and protecting the common good. But whatit actually means to protect the common good is rarely scrutinized. There are two conceptions of thecommon good that provide very different accounts
OECD GUIDELINE FOR TESTING OF CHEMICALS Bacterial Reverse Mutation Test INTRODUCTION The bacterial reverse mutation test uses amino-acid requiring strains of Salmonella typhimurium and Escherichia coli to detect point mutations, which involve substitution, addition ordeletion of one or a few DNA base pairs (1)(2)(3). The principle of this bacterial reverse mutationtest is that it de
