PREFACE
This volume contains the proceedings of the International Conference on
Prostaglandins and Lipid Metabolism in Radiation Injury held in Rockville,
Maryland, on October 2-3, 1986. Over 200 persons from eight countries attended
the program, which consisted of 24 oral presentations and 38 poster presentations.
Forty-two of those presentations have been included in this volume. The conference
was sponsored by the Armed Forces Radiobiology Research Institute, located in
Bethesda, Maryland.
The effects of radiation on lipid synthesis and membrane damage are aptly
summarized in the first five chapters. These chapters describe the effects of radiation
on lipid peroxidation of model membranes, and the role of lipid composition in
mammalian cell death and in bacterial radio- and thermosensitivity. In bacteria,
lipid peroxidation is not essential for radiation-induced cell death.
One of the key points of the conference was the paradoxical nature of the
radiobiology of eicosanoids. On the one hand, eicosanoids are mediators of damage;
on the other, they are radioprotective agents. It is clear from the literature and
from the data presented at the conference that both of these properties may also
be observed as a consequence of radiotherapy. Some studies indicate that
nonsteroidal anti-inflammatory drugs may minimize or prevent certain radiation
induced damage, but other studies show no positive effect. It was pointed out at
the conference that care should be exercised in manipulating the eicosanoid response
of tumors to favor radiotherapy because in blocking either the cyclooxygenase
pathway or the lipoxygenase pathway, arachidonic acid may be shunted through
the other pathway and elicit similar radiation-induced damage or tumor protection.
Two additional chapters are devoted to prostaglandins and cancer, showing the
potential uses of nonsteroidal anti-inflammatory drugs in therapy and also
demonstrating that prostaglandins are radioprotective to tumor cells. Both the
prostaglandins and the leukotrienes have been shown to exhibit radioprotective
qualities. In addition, the latest information has been included on the alteration
of prostaglandin levels in humans following total-body irradiation for bone marrow
transplants. The increase in urinary 6-keto PGF1a has now been observed in humans
and in laboratory animals postirradiation.
The conference highlighted a number of methods for the detection and quantitation
of lipid peroxidation and eicosanoids. The proceedings is organized to reflect the
methods of detecting eicosanoids and lipid peroxidation, and summarizes the state
of the art in those fields. The definitive detection is represented by the extreme

sensitivity and characteristic spectral analysis of the GC-mass spectrometer, with
which femtogram quantities can be detected. The rapidly developing field of enzyme
labeled immunoassay (ELISA) is summarized, including the detection of eicosanoids
using acetylcholine esterase. This technique permits the detection of eicosanoids
down to one picogram per well and does not require the use of radiolabeled
compounds. A relatively new technique for the introduction of nonvolatile samples
for mass spectroscopic analysis is the thermospray interface. As new techniques
and lower limits of sensitivity have been acquired, the list of eicosanoid metabolites
and their biological properties that have been identified will most certainly grow.
The picture becomes more complicated in accounting for the metabolites, the
distributions, and their contributions to either radiation injury or radioprotection.
The effects of ionizing and nonionizing radiations on eicosanoid and lipid
metabolism are presented on experimental systems ranging from liposomes and
bacteria to man. Very little work has been done with either the platelet-activating
factor or leukotrienes regarding their roles in radiation injury. Reports in this volume
demonstrate that the production of both compounds is increased in response to
radiation exposure. The conference has summarized much of the complexity within
the field and pointed out the need for more research and, perhaps, the need for
a future conference.
