Biotechnology and Medicine
Introduction
With the advent of improved sanitation and living conditions, together with vaccination and antibodies, life expectancy over the last 150 years has rapidly increased from 35 to almost 80 years, with further improvement expected. Nowadays in advanced societies, infectious diseases are no longer the main threat to life but rather it is the chronic diseases (cancer, cardiovascular diseases, Alzheimer’s disease, etc.) that plague our increasingly ageing populations.

It is now believed that the solution to these chronic diseases could come through genetic medicine and that modern biotechnology will play a major role. While this will undoubtedly be true in part

Especially where single gene changes are responsible, it must be recognized that many chronic diseases will most probably not have a single, identifiable genetic cause but rather arise from a complex, cascading series of biological events interacting with environmental factors. The impact of pharmaceuticals on human health care is an area where biotechnology innovations are likely to have the earlier commercial realization. New medical treatments based on biotechnology are appearing almost daily in the market place. These include:
therapeutic products (hormones, regulatory proteins and antibiotics) prenatal diagnosis of genetic diseases vaccines immunodiagnostics and DNA probes for disease identification and genetic therapy (This is the largest commercially developed area of new biotechnology, with massive present and future markets and can only be selectively examined here).
