Proceedings from the September 1988 meeting. The major emphasis is on new polymeric materials, and papers are grouped into sections on various applications: opthalmic; surgical, dental, and diagnostic; and controlled release and bioactive polymer applications.

Polymers continue to show almost amazing versatility. We have always known that polymers could be used for trinkets, toys and dishes. Now, however, we are no longer surprised to encounter these adaptable mate- rials in almost every place we look. We find them in our cars, tools, electronic devices, building materials, etc. The use of polymeric mate- rials in medicine is also well documented in previous books by one of the Editors (Gebelein) and by others. Likewise, the use of polymeric mate- rials in pharmaceutical applications, especially in controlled release systems, is also well...

The art of using chemical agents for medication dates back into antiquity, although most of the earliest examples used plants, herbs, and other natural materials. The old Egyptian medical papyri, which date from before 1400 B. C., contain dozens of examples of such medicinal plants and animal extracts. In the Old Testament of the Bible, we can find references to using oil to soften the skin and sores (Isaiah 1:6), the use of tree leaves for medicine (Ezekiel 47:12) and various medical balms (Jeremiah 8:22). Not all these recipes were effective in curing the ailments for which they were used...

Some have predicted that the coming several decades will be the decades of "biotechnology," wherein cancer, birth defects, life span increases, cosmetics, biodegradation, oil spills and exploration, solid waste disposal, and almost every aspect of our material life will be affected by this new area of science. There will also be an extension of emphasis on giant molecules: DNA, enzymes, polysaccharides, lignins, proteins, hemoglobin, and many others. Biotechnology has been defined in various ways. In one sense, this field is older than human history and references to the human use of...
