Abstract
While directing the microvascular cast of a sample of fresh brain under binocular microscope with methyl methacrylate, the specimen surface vacuum evaporation treating unit has been sprayed 100aA golden membrane for microvascular cast, on the condition of accelerating voltage 20kV and probe current 0.02nA, with the scanning of EPM Shimadzu Corporation JAPAN. You will find that the corterartery of brain substance artery has various types of the branches, the blood capillary circulation tallies one with another to form well developed blood capillary network and there are cobble-like marks formed by internal cells on the surface of arteriole blood vessels.Mixing nine methyl methacrylate with one methyl acrylate and adding into it 6% benoyl peroxide of the liquids above, putting this mixture into a cone-shaped bottie , and heating the liquid to 80-P5 C, when the solution is gradually getting dense set and is ready to gettogether.
