Preface
Magnesium: New Vistas
Eighteen years after the 5th International Magnesium Symposium was held in 
Kyoto in 1988, the Japanese Society for Magnesium Research (JSMR) is orga-
nizing the 11th International Magnesium Symposium in ISE-Osaka. The vital-
ity of the Japanese Society has been evidenced by the regular publication of 
its journal (Journal of the Japanese Society of Magnesium Research), which 
ensures regular updating of current Japanese research on magnesium, and by 
its participation in the activities of the international Society for the Develop-
ment of Research on Magnesium (SDRM).
Thanks to the effi cient management of Yoshiki Nishizawa, Hirotoshi Morii, 
and Masaaki Inaba, the publication of this book of proceedings provides new 
vistas on magnesium research in 2006. It comprises reports presented during 
the plenary sessions concerning the role of magnesium not only in physiology, 
chronobiology, nutrition, epidemiology, and internal medicine particularly, 
cardiology, neurology, rheumatology, gynecology, and nephrology, but also in 
stomatology, pharmacognosy, and veterinary medicine.
Unlike many books that promise more than their texts deliver, the multi-
plicity and interest of the discussed topics can but stimulate careful reading 
of this book, which gives a platform to authors originating from many parts 
of the world. Published 35 years after the 1st International Magnesium Sym-
posium, it demonstrates that magnesium research stands the test of time and 
that a wide path remains open for further investigation.
Such as it is, this book provides a valuable tool for interdisciplinary research 
in the future.

Preface
New Perspectives in Magnesium Research is published as a document of the 
11th International Magnesium Symposium, a joint meeting of Japanese Society 
for Magnesium Research. Professor Jean Durlach has been President of Inter-
national Society for Magnesium Research since it was established in 1970. 
There are international meetings every 2 to 3 years in many parts of the world. 
The last meeting hosted by the Japanese Society for Magnesium Research was 
in Kyoto in 1988, when the Society President was Professor Yoshinori Itokawa.
Magnesium is the most abundant cation, second only to potassium in the 
intracellular compartment and to calcium in bone tissues. One of the big dif-
ferences between calcium and magnesium is the difference between intra- and 
extracellular levels. Extra- and intracellular ratio is 10,000 for calcium, but 
0.33 for magnesium. Such facts have signifi cance for maintenance of life. 
Intracellular space rich in magnesium is just like seawater, adequate for the 
origin of life and maintenance of life in sea animals and plants. Bone magne-
sium constitutes a part of hydroxyapatite and may be important in maintain-
ing bone integrity.
In physiological situations, magnesium is involved in metabolism of fat, 
amino acids, and sugar. Magnesium plays an important role in PPAR (peroxi-
some proliferators-activated receptor)–mediated signaling pathways as a key 
cofactor in the protein phosphorylation.
In bone and calcium metabolism, magnesium seems to play roles as a con-
stituent of bone. Experimentally, magnesium defi ciency induces osteoporosis 
but there have not been defi nite evidences of correlation between osteoporosis 
and  magnesium.  In  calcium-  and  magnesium-defi cient  animals,  calcium 
restores the bone quality but magnesium only partially. Another aspect of role 
of magnesium is the regulation of calcium metabolism through calcium-
sensing receptor, which requires magnesium for its action. Another point is 
how magnesium participates in vitamin D action. Vitamin D is another impor-
tant factor, other than calcium-sensing receptor, that requires magnesium in 
its action. The correlation between calcium-sensing receptor and vitamin D 
receptor has been discussed. Thus, magnesium plays some roles in the regula-
tion of calcium and bone metabolism.
viii    Preface
Clinically, diabetes mellitus, atherosclerosis, hypertension, cardiovascular 
diseases,  and  hyperlipidemia  are  in  some  other  ways  infl uenced  by 
magnesium. More evidence is needed to have a defi nite conclusion how to 
manage  clinical  problems,  problems  of  public  health,  and  individual 
nutrition.
