合方治疗脑缺血12小时组缺血脑组织TGF-β1光密度值较缺血12小时模型组无显著性差异（p＞0.05）。本实验结果发现，与单纯缺血12小时、24小时大鼠相比，药物干预组缺血侧大脑皮层TGF-β1免疫反应明显增强，计算机辅助图像半定量分析两组间缺血侧大脑皮层TGF-β1免疫阳性细胞数差异非常显著。说明药物对局灶性脑缺血损伤可能有一定保护作用，其机制可能与诱导脑细胞TGF-β1合成增加有关。然而，药物调控TGF-β1表达，其促TGF-β1表达增强的机制可能是这样的：脑缺血时TGF-β1mRNA表达增加可能与缺氧诱导神经和胶质细胞刺激生长因子表达有关。

12H treatment group compared with 12h model group: the level of MCP-1 of the Gardenoside group decreased and MIP-1 is no different with the model group; the level of the MCP-1, MIP-1 of the Baicalin group are no different with the model group; the level of MCP-1, MIP-1 of the Concha Margatitifera Usta decreased than the model; the level of MCP-1 of the Cholic Acid group is no different and the level of MIP-1 decreased than the model; the level of MCP-1 of the Hefang Group decreased and the level of MIP-1 of it decreased than the model group.

合方治疗脑缺血24小时组缺血脑组织nNos光密度值较缺血24小时模型组明显降低（p＜0.01）。细胞的死亡分为坏死和凋亡两种方式，凋亡是细胞为避免对机体造成更大损伤而采取的一种程序性的死亡方式。珍珠母、胆酸、栀子苷、黄芩苷、合方治疗组较脑缺血24小时模型组可明显降低P53阳性表达，考虑药物抑制细胞凋亡可以起到对缺血脑组织的保护作用。

Slit-lamp biomicroscopy photography, and immunohistochemical staining were done. The area of CNV was calculated and the average optic density of immunohistochemical staining of iNOS was measured after 8 hours and 1, 4, 7, 14 and 28 days by imaging analysis system.

The total RNA from brain tissue of substantia nigra of PD rats is extracted at the 1st, 2nd, 4th and 8th week and comparison is made between it and that from normal rats. The total RNA, after RNA formaldehyde degenerated sepharose electrophoresis and separation and Northern transfer, is adsorbed unto colloxylin membrane. Then ECL labeled Selenoprotein P and an unknown gene fragment are used as probes to hybridize with the RNA on the colloxylin membrane. And the hybridized result is obtained with enzyme-linked immunosorbent assay. Finally, analysis of OD is made using ONE-Dscan software.
