Objective: To study the intervention effect of Peiyuan Huayu Decoction on the neuron damage
in model rats with acute subdural hematoma (ASDH). Methods: 160 SD rats were randomly
divided into four groups, and the ASDH model rats were made by stereotactic autoblood
injection, and sham operation group received craniotomy without blood injection. Sham
operation group and model group were normally bred after model establishment, and 6 h
after model establishment, the treatment group received intragastric administration of Peiyuan
Huayu Decoction, and control group received intragastric administration of Piracetam Tablets,
1 time a day. On the 1d, 3d, 5d and 7d after model establishment, the general conditions of rats
(activity, food intake and mental state) were observed, blood was collected via auricula dextra,
ELISA method was used to determine peripheral plasma NSE and S100毬 protein contents,
routine HE staining was conducted after perfusion fixation, the neurons in blood injection
side of brain tissue were counted, and the neuron damage was observed. Results: 26 rats were
dead in the experiment. The general conditions of sham operation group were significantly
better than those of other groups, treatment group was significantly better than model group
and control group on the 5d group (P<0.05), and there was no significant difference on the
1d, 3d and 7d (P>0.05); neuron count of sham operation group was basically stable, treatment
group was not different from model group and control group on the 1d (P>0.05), treatment
group was better than model group (P<0.05), and not different from control group (P>0.05) on
the 3d, and treatment group was better than model group and control group on the 5d and 7d
(P<0.05); peripheral plasma S100毬 protein and NSE contents of sham operation group were
at lower levels, treatment group was not significantly different from model group and control
group on the 1d (P>0.05), S100毬 protein and NSE contents decreased significantly on the 3d,
and treatment group was significantly different from model group and control group (P<0.05),
S100毬 protein and NSE contents increased on the 5d and 7d, the increase in treatment group
was slower than that in model group and control group, and there was significant difference
(P<0.05). Conclusion: Peiyuan Huayu Decoction has obvious protective effect on the neurons
in ASDH model rats, and this effect may be based on the inhibition of secondary neuron
damage.
