Abstract:
Objective To observe the influence of Xiaoshuan enteric-coated Capsule (XSECC) on neuronal damage in cortex of cerebral hypo-perfusion rats. Methods Rats were divided into a sham group (12), a model group (17), a XSECC large dose group (15), a medium dose group (15) and a low dose group (15) by a random number table. The cerebral hypo-perfusion model was produced by permanent bilateral common carotid artery ligation (2VO). The mixed suspension of XSECC was given orally to rats in the XSECC large dose group (420 mg/kg), the medium dose group (140 mg/kg) and the low dose group (47 mg/kg) once each day for 40 days from the beginning of two hour after ischemia. The expressions of NeuN and Caspase-3 were observed by immunofluorescence staining at 40 days after ischemia. The content of GSH-PX,SOD and MDA were measured by biochemical assay. Results Compared to the model group, the expressions of NeuN (8 716.86 ± 2 539.93, 9 549.31 ± 1 663.26 vs. 7 297.05 ± 1 932.49) were significantly increased in the XSECC large dose group and the medium dose group (P<0.05 or P<0.01);The content of GSH-PX (7.37 ± 1.08 U/mg, 7.77 ± 3.26 U/mg vs. 3.67 ± 2.52 U/mg) was increased in the XSECC large dose group and the medium dose group(P<0.05); The expressions of Caspase-3 (11.65 ± 2.68, 14.05 ± 4.55, 12.60 ± 4.56 vs. 16.80 ± 5.41) were obviously decreased in the XSECC large dose group, the medium dose group and the low dose group, compared with the model group (P<0.05 or P<0.01);The content of MDA (1.44 ± 0.40 nmol/mg, 1.96 ± 1.13 nmol/mg, 2.12 ± 1.19 nmol/mg vs. 3.19 ± 0.98 nmol/mg )was decreased in the XSECC large dose group, the medium dose group and the low dose group when compared with the model group (P<0.05 or P<0.01);The content of SOD (555.61 ± 92.45 U/mg, 607.90 ± 228.45 U/mg, 515.98 ± 184.01 U/mg vs. 348.12 ± 108.84 U/mg) was increased in the XSECC large dose group, the medium dose group and the low dose group when compared with the model group (P<0.05 or P<0.01). Conclusion XSECC could protect injured neurons, which is related to the improvement of free radical metabolism.
