We O

Although O

Here O

BACKGROUND O
: O
Studies O

PPARa O
is O

in O

However O

METHODS O
: O
Here O
we O
set O

RESULTS O
: O
Quantitative O
PCR O
indicated O
that O
PPARa O
is O
well O

in O
human O
liver O

human O

that O
the O

that O

Many O

Among O
the O

between O

that O

PPARa O
is O
much O
better O
captured O
by O

In O

Finally O
, O
several O
putative O

genes O

PPARa O

identified O
that O
were O

that O

CONCLUSION O

In O

In O

a O

also O
observed O

but O
less O

a O

level O
. O
Based O
on O
the O
finding O
that O
VPU O

could O
protect O
the O
animals O
against O
pilocarpine O
- O

it O
is O
suggested O
that O
the O
reduction O

was O
comparatively O
minor O

offset O
by O
a O

Therefore O
, O

finding O
that O

could O
drastically O
reduce O
pilocarpine O

We O
suggest O
that O
DHEA O

The O

our O
