摘要: 探讨二十五味珊瑚丸(25 Odors Coral Pills)对D-半乳糖(D-gal)衰老大鼠海马锥体细胞形态和神经元特异性烯醇化酶(NSE)表达的影响。采用颈背部皮下注射D-gal模拟衰老大鼠模型。治疗组于造模第6周,给予25 Odors Coral Pills灌胃2周,之后取各组脑组织行相关检测。与模型组比较,25 Odors Coral Pills组大鼠海马CA1、CA3区锥体细胞层细胞丢失较少,细胞排列较紧密、整齐;DG区NSE阳性的细胞减少,胞体较小,突起较细;海马NSE表达下降,有统计学差异(P<0.05)。D-gal衰老模型鼠海马锥体细胞衰老变性且NSE 的表达增多;25 Odors Coral Pills可抑制D-gal衰老鼠海马锥体细胞的衰老变性和NSE的表达。

Abstract: The D-galactose induced brain aging model was used to study the effect of 25 odors coral pills on hippocampus.The morphology of pyramidal cells and the expression of neuron-specific enolase (NSE) in hippocampus were determined in each experimental group.Hippocampal neuronal degeneration on CA1,CA3,DG region was observed by hematoxylin-eosin staining.The expression of NSE was explored by immunohistochemistry,Western blotting and densitometric analysis.The results showed that the degeneration of hippocampal pyramidal cells in 25 odors coral pills group was significantly improved,and the number of cells positive for NSE and the expression of NSE in the hippocampus were significantly reduced.These results indicated that 25 odors coral pills can inhibit hippocampal neuronal degeneration and the expression of NSE protein in the D-galactose induced brain aging rats.

Key words: 25 odors coral pills, NSE, D-galactose, aging, pyramidal cells
