Stjarne: The present review puts the emphasis on two important
developments: the discovery that individual postganglionic
sympathetic neurons may secrete multiple transmitter substances
from different classes of vesicles and by different mechanisms, and
the introduction of new techniques which may permit for the first
time direct impulse by impulse analysis of transmitter secretion in
individual sympathetic nerve varicosities. Illes: Exogenous and
endogen opioid peptides elicit a number of effects in the organism,
usually by modifying the function of transmitter and hormone
systems, for example, activation of multiple opioid receptors. The
effects of opioids on transmitter and hormone release have
frequently been reviewed. This review gives a detailed overview on
the involvement of multiple opioid receptors in these processes.
Rothstein: This article gives an overview of the exchange in
acidification and transepithelial salt and water transfer in
nonepithelial cells. Delineating the exchanger's most important,
common features, and concentrating particularly on its role in cell
pH and volume regulation.
The First International Symposium on the Metabolic Interconversion
of Enzymes was held in Santa Margherita Ligure, Italy, in May,
1970, under the direction of Professor G. Bonsignore. Because of
rapid developments in this field, a second Symposium was organized
a year and a half later in Rottach-Egern, Germany (October, 1971)
by Professors E. He1mreich, H. Holzer and O. Wieland. At that time,
so much new information had accumulated that it was decided to
repeat such conferences approx imately every other year; the United
States was chosen as the next site. This publi cation reports the
Proceedings of the Third International Symposium on the Metabolic
Interconversion of Enzymes held at the Battelle Seattle Research
Center, Seattle, Washington, June 5 - 8, 1973. The conferences were
originally designed to examine the control of metabolic reactions
by covalent modification of certain key enzymes. Covalent, as
opposed to allosteric or metabolic, regulation had first been
recognized some fifteen years be fore. Initially thought to
represent an added sophistication in regulatory processes possibly
reserved to higher organisms, covalent regulation has now been
found in both prokaryotes and eukaryotes. Those early studies in
covalent modification revealed for the first time the existence of
special "converter" enzymes whose purpose in life is to switch
other molecules from one state of activity to another."

This book is a compilation of formal presentations made during a
three-day invitational conference at Battelle Research Center in
Seattle, Washington. The purpose of organizing and publishing the
proceedings of the conference is to provide a comprehensive survey
of present knowledge on the determinants of membrane structure, the
molec ular specificity of membrane function, and the dynamic
properties of membranes. Each presentation was followed by
discussions which, be cause of their informal and spontaneous
character, have not been in cluded in this publication. Molecular
studies of biological membrane phenomena have progressed over the
past decade to the point where it is now realistic to expect future
resolution of the physico-chemical processes or forces governing
the organization, function, and dynamic properties of membranes.
Drs. Radda, Kaback, and Schwyzer, each presenting a different
approach to the biochemical and biophysical study of membranes,
devoted four to six weeks as Battelle Visiting Fellows to
developing the format and the roster of participants of the
conference. The scientific "cluster" concept for planning the
conference is reflected in the breadth of topics presented in this
publication."
