摘要

To observe the effect of early intervention using extract of Huannao Yicong Decoction (还脑益聪方

HYD) on the pathological picture of hippocampus

neurocyte apoptosis

and associated regulatory genes in β-amyloid precursor protein (APP) transgenic mice model of dementia. Sixty APP695V7171 transgenic mice were randomly divided into four groups of 15. The model group was treated with distilled water

the positive control group was treated with donepezil (0.65 mg/kg)

and the two HYD groups were treated with high dose (2.8 g/kg) and low dose (1.4 g/kg) HYD

respectively. All testing drugs were administered through gastrogavage by dissolving in equal volume of distilled water

once a day for six successive months. In addition

a normal control group with 15 healthy C57BL/6J mice of the same age and genetic background was set up with distilled water treatment. The pathologic picture of brain tissue was observed by microscopy with HE stain; the amount of apoptosis cells in the hippocampal CA1 area was detected by TUNEL; and expressions of associated genes

Bcl-2

and Bax were determined by immunohistochemical method. Pathologic pictures of hippocampus showed that in the model group

cells messily arranged

neurons markedly decreased

and the surrounding tissue of some cells was loosened with edema

necrosis

and widened gap with glia cells proliferation. Compared with those in the normal group

the amount of apoptosis cells in the CA1 area was increased

Bcl-2 expression decreased

and Bax expression increased significantly

with markedly reduced Bcl-2/Bax ratio in the model group. Compared to the model group

the pathological changes were significantly milder in the HYD-treated groups

showing rather regularly arranged cells

significantly increased neurons

only few denatured necrotic cells with milder edema

less proliferation of glia cells

and obviously reduced cell apoptosis in CA1 area (P<0.05 or P<0.01). Besides

Bcl-2 expression was up-regulated and Bax expression down-regulated

and Bcl-2/Bax ratio significantly increased in the two HYD groups (P<0.05 or P<0.01). Early intervention with HYD could improve the abnormal pathologic picture of hippocampus and regulate the expressions of associated genes to suppress cell apoptosis

which might be its mechanism of action in alleviating cognitive functional disorder.
