Five non overlap visual fields at ischemic region were ran domly observed underneath 400 fold light microscope. Quan tity A single software package was utilised to analyse the gray worth and took the imply. The alter of myelin was presented by myelin gray value. Transmission electron microscopy Ultrathin sections, Took some fresh brain tissue from the ischemic location and reduce into pieces of one mm × one mm × one mm, fixed with two. 5% glutaraldehyde for 24 h and 1% osmium tetroxide for 2 h and dehydrated by graded series of acetone. Then soaked with all the mixture of acetone and embedding answer for one. five h and pure embedding resolution overnight at 37 C respect ively. The samples have been place in to the embedding plate full of epoxy resin Epon812 to form embedding blocks finally.

The 50 nm ultrathin sections have been lower by the ultramicrotome and positioned around the nets prepared with polyvinyl formal, stored at four C. TEM, Dripped a drop of 3% uranyl acetate alcohol sat urated remedy within a petri dish, covered the nets of ultrathin sections to make contact with using the dye mTOR inhibition liquor to stain for thirty min, and rinsed with double distilled water for ten min × three occasions to suck up water. Then, cov ered the nets of ultrathin sections to a drop of 6% lead citrate dye liquor in a further petri dish to stain for five min, rinsed with non carbon dioxide double distilled water for 10 min × three times, dried at space temperature. The ultrastructure of myelin was observed below TEM. Immunohistochemical assay Paraffin sections prepared as over have been dewaxed and washed routinely, operated by the specification of SABC kit, created by DAB chromogenic reagent kit and re stained by hematoxylin.

Below light microscope myelin showed claybank streak and constructive cells cytoplasm presented uneven coloring, vacuolization in cells. Nega tive handle slices were dyed with 0. 01 mol L PBS in stead of rabbit anti rat MBP major antibody selleck chemical and no beneficial reaction appeared. 5 non overlap visual fields randomly at ischemic location were chose underneath 400 fold light microscope. The gray worth was analysed by the program of Quantity One particular and final took the indicate. The expressing intensity of MBP was presented by gray value of myelin. Western blot Extraction of complete protein, Soon after treatment method 24 h, we ran domly chose five rats from control group, five from model group and from therapy group to perfuse from heart with standard saline 200 ml following anesthe tizing by 10% chloral hydrate. Took 200 mg ischemic brain tissue and place it into 1. five ml EP tubes, extra cell lysis buffer as the proportion of one,four.
