Effect of Sijunzi Tang on Behavior and Energy Metabolism of Hippocampal Neurons in Rats with Alzheimer's Disease
To observe the changes of behavior and mitochondria in Alzheimer's disease(AD) rats
and to explore the mechanism of Sijunzi Tang in the treatment of AD rats′ behavior and the changes of mitochondrial energy metabolism in hippocampal neurons.
Method:
2
The 60 male SPF grade rats were randomly divided into normal group
model group
low
medium and high dose group of Sijunzi Tang(3.24
6.48
12.56 g·kg
-1
)
and dihydroergot group (0.27 mg·kg
-1
)
10 rats in each group. The normal group received no intervention and had a normal diet. The rest of the rats were injected with
D
-galactose to the abdomen at a dose of 200 mg·kg
-1
once a day for 6 weeks. Morris water maze experiment was used to detect the cognitive function of rats. Tm-Vision behavioral experiment system was used to observe the behavioral changes of rats
and the hippocampal neuronal line structure was observed by transmission electron microscope. Mitochondrial complex colorimetry was adopted to detect rats CⅠ
CⅡ
CⅢ
CⅣ activity.Western blot was used to detect the expression of mitochondrial adenosine monophosphate-activated protein kinase(AMPK) protein in the hippocampus.
Result:
2
Compared with normal group
model group rats latent escape period time increasing
through fewer
movement distance
movement time increasing
center residence time increased (

mitochondria CⅡ
CⅢ
CⅣ activity decline (
P
<

P
<
0.01)
The AMPK protein expression increased significantly (
P
<
0.05
P
<
0.01). Compared with model group
Sijunzi Tang medium and high dose group and dihydroergot decoction group showed decreased latency
increased crossing times
decreased exercise distance
decreased exercise time
and decreased center residence time (
P
<
0.05
P
<
0.01). Compared with model group C Ⅱ
mitochondrial complex CⅣ activity increases
AMPK protein expression lowered (
P
<
0.05
P
<
0.01)
Sijunzi Tang high dose group of mitochondrial complex C Ⅱ
C Ⅲ activity increased significantly
AMPK protein expression significantly lowered (
P
<
0.05
P
<
0.01).
Conclusion:
2
The abnormal behavior of AD rats may be related to the decrease of central hippocampal energy metabolism and mitochondrial function. Sijunzi Tang has therapeutic effect.
