Introduction and Aim
Hydrogen
sulphide,
generated
endogenously in mammalian tissues, is a
synaptic modulator and neuro protector in
the brain increasing the levels of
gluthathione, a major cellular antioxidant.
The role of hydrogen sulphide in
inflammation is controversial and complex
showing pre inflammatory and anti
inflammatory effects depending on its
concentrations and the donor used. Besides
that endogenous production of hydrogen
sulphide, it is known that thermal waters
rich in sulphur are exogenous sources of
this molecule, and they have been
traditionally used in bath therapies because
of their beneficial effects on human health.
As the ageing process is a chronic oxidative
stress situation with a decrease of
gluthathione levels and a nervous and
immune systems deterioration, the objetive
of the present work was to investigate in
old mice the role of baths with sulphurous
thermal waters in several nervous and
immune functions as well as gluthathione
leukocyte levels.

Design and Methods
Twenty months old female ICR-CD1 mice
were used. They were divided in three
groups: the first was submitted a daily bath
of 15 minutes in sulphurours water (called
"sulphurours water group", SWG), the
second in normal water (called "control
water group", CWG), and the third was
mantained in the cage ("control sedentary
group", CSG). The treatments were
performed during two weeks, five days per
week. Neuromuscular coordination was
analyzed through the tightrope test, and the
exploratory and anxiety-like behaviours by
open field, holeboard and T-maze tests. In
addition, peritoneal leukocytes were
obtained and macrophage phagocytosis,
digestion capacity (intracellular reactive
species (ROS) levels), natural killer (NK)
activity against tumour cells and total GSH
levels, determined.
Results
The results show that the neuromuscular
vigour and exploratory capacities are
improved and anxiety reduced in animals of
SWG with respect those in CSG, and in
some parameters they are better than mice
of CWG. The GSH levels were higher in
leukocytes from SWG than in the other
groups. The phagacytosis was also higher in
macrophages from SWG than from CWG
and in the animals of this group than those
of CSG. The NK activity was higher in
leukocytes from SWG and CWG with
respect to those of CSG.
Conclusions
Bath sessions in thermal water rich in
sulphur compounds improve several
nervous system functions and peritoneal
cell activities as well as the redox state of
these cells in old mice. Since the immune
parameters studied, which show an agerelated deterioration, are markers of
biological age and longevity, this
improvement suggests that the bath
treatment is a good strategy to slow down
the ageing process and reach a healthy
longevity.

INTRODUCTION AND AIM
DESIGN AND METHODS
Hydrogen

gluthatione
(GSH),
a

is controversial and complex showing proinflammatory or anti-inflammatory effects
depending on its concentrations and the
