Diffusion Kurtosis Imaging (DKI) provides quantifiable information on the non-Gaussian behavior of water diffusion in biological tissue. Changes in water diffusion tensor imaging (DTI) parameters and DKI parameters in several white and gray matter regions were investigated in a mild controlled cortical impact (CCI) injury rat model at both the acute (2 h) and the sub-acute (7 days) stages follo...
Normal astrocytes in the adult undergo hypertrophy and proliferation and transform into reactive astrocytes following many types of central nervous system (CNS) injury (1–5). This process is termed astrogliosis and may result in the formation of a glial scar. Morphological studies on astrogliosis by neuroanatomists and pathologists at the beginning of this century focused on the most florid exa...
The role of mononuclear phagocytes in wound healing after traumatic injury to adult mammalian brain.
We monitor cellular responses to a penetrating wound in the cerebral cortex of adult rat during the first weeks after injury. Two classes of activated mononuclear phagocytes containing acetylated low-density lipoprotein (ac-LDL) receptors appear within hours at the wound site. One type of cell surrounding the lesion edge had thin, delicate processes and is identical in appearance to ramified mi...
