学习 Zuogui 药片的效果的目的(, ZGP )并且 Yougui 药片(, YGP )在导出大脑的神经营养的因素( BDNF )和周期的腺苷的表情上与试验性的自体免疫的脑脊髓炎( EAE )在吊楔老鼠 axonal 新生发信号的 monophosphate (营地) /protein kinase A ( PKA ),以便在支持 axonal 新生上探索 ZGP 和 YGP 的可能的机制。老鼠随机被划分成正常控制(NC ) 的方法,模型(瞬间) ,泼尼松醋酸盐(PA ) , ZGP 和 YGP 组。老鼠的 EAE 模型被注射包含髓磷脂的抗原建立基本蛋白质(MBP ) 6886。大脑和针的绳索在 第14 和 第28 天被收获免疫以后( PI ),蛋白质和在大脑和老鼠的针的绳索的 BDNF 和 PKA 的 mRNA 表示被西方的污点分析和即时量的聚合酶链反应( PCR )检测,并且营地层次被使用酶免疫分析方法检测。第 28 天 PI 上的结果(1 ) ,在大脑白人物质和在 ZGP 和 YGP 组的老鼠的针的绳索的 BDNF 的 mRNA 表示是起来调整的,特别在 YGP 组(P < 0.05 或 P < 0.01 ) 。( 2 )在 第14 天 PI 上,在显著地与瞬间相比在 PA 和 YGP 组增加的大脑白人事的营地层次组织( P < 0.05 或 P < 0.01 ),并且在 YGP 组的营地水平在 ZGP 组比那高( P < 0.05 )。在针的绳索的营地水平显著地也与瞬间, PA 和 ZGP 组相比在 YGP 组增加了,分别地(P < 0.01 ) 。(3 ) 在第 14 天 PI 上,在在 ZGP 组的老鼠的针的绳索的 PKA 表示显著地与瞬间和 YGP 组相比被减少,分别地(P < 0.05 ) 。(4 ) 在第 28 天 PI 上,在 YGP 老鼠的大脑白人事在营地和 PKA 表示之间有积极关联。结果建议那 ZGP 和 YGP 的结论可以由 modulating cAMP/PKA 信号 transduction 小径支持 axonal 新生,但是 ZGP 的分子的机制的目标可能与 YGP 的那些不同。
Objective:To study the effects of Zuogui Pill(左归丸,ZGP)and Yougui Pill(右归丸,YGP)on the expressions of brain-derived neurotrophic factor(BDNF)and cyclic adenosine monophosphate(cAMP)/protein kinase A(PKA)signaling of axonal regeneration in the Lewis rats with experimental autoimmune encephalomyelitis(EAE),in order to explore the possible mechanism of ZGP and YGP on promoting axonal regeneration.Methods:The rats were randomly divided into normal control(NC),model(MO),prednisone acetate(PA),ZGP and YGP groups.The EAE model of rat was established by injecting antigen containing myelin basic protein(MBP)68-86.The brain and spinal cord were harvested on the 14th and 28th day postimmunization(PI),the protein and mRNA expression of BDNF and PKA in the brain and spinal cord of rats were detected by Western blot analysis and real-time quantitative polymerase chain reaction(PCR),and the cAMP levels were detected by using enzyme-immunoassay method.Results:(1)On the 28th day PI,the mRNA expression of BDNF in brain white matter and spinal cord of rats in ZGP and YGP groups were up-regulated,especially in YGP group(P〈0.05 or P〈0.01).(2)On the 14th day PI,the cAMP levels in brain white matters significantly increased in PA and YGP groups compared with MO group(P〈0.05 or P〈0.01),and the cAMP level in YGP group was higher than that in ZGP group(P〈0.05).The cAMP level in spinal cord also significantly increased in YGP group compared with MO,PA and ZGP groups,respectively(P〈0.01).(3)On the 14th day PI,the PKA expression in spinal cord of rats in ZGP group was significantly decreased compared with MO and YGP groups,respectively(P〈0.05).(4)On the 28th day PI,there was a positive correlation between cAMP and PKA expression in the brain white matter of YGP rats.Conclusions:The results suggest that ZGP and YGP may promote axonal regeneration by modulating cAMP/PKA signal transduction pathway,but the targets of molecular mec
