Experimental Studies on Capillary Vessels, Structural Density of Nissl's Gray Substance and Ketoenolic Granules (KEG) in the Brain of Cats and Rabbits with Old Latent Local Cerebral Anaphylaxis (LLCA) Parl I. Studies on the capillary vessels in the brain with LLCA

LLCA of cats were produced by using inactive cow serum and LLCA of rabbits were by alpha-streptococcns. The motor cortex and nucleus lenticularis were investigated microscopically. The capillary vessels were studied with Campbell-Wake's capillary vessels representation method and gutta percha injection into the common carotid artery. The capillary vessels of LLCA were fragmentally broken by Campbell-Wake's method for 1 or 2 months after the last injection of antigen, but 3 months later no difference was observed between LLCA and the normal ones. Therefore, it was presumed that the capillary vessels of the brain with LLCA were spastic, at least for 1 month after the last injection.
