Abstract
Adult rabbits received stab wound in the cerebrum and were sacrificed at intervals of 20, 30, and 39h thereafter. Each animal was injected intracere-brally with3H-thymidine 2 h before fixation. Altered brain tissues of the stratum radiatum of hippocampus were taken for examination. Response of “resting microglia” to stab wounding was investigated by electron microscopic autoradiography and by autoradiography applied on silver-impregnated materials. Following results were obtained: (1) Resting microglia undergo marked swelling shortly after the brain damage. We designate these cells as “swollen microglia”. (2) Swollen microglia form the only cell population that proliferate actively in the initial stage of glial response to the brain injury, and (3) astroglia do not proliferate during the same experimental periods, in the rabbit hippocampus.This publication has 27 references indexed in Scilit:
