[Sympathetic and parasympathetic centers of the brain and spinal marrow of rats during exposure to +Gz].
Structural transformations in the dorsal vagal complex and intermediolateral nucleus due to +G, loads were studied in white outbred male rats centrifuged according to the standard procedure (P.S.Paschenko, 1995). Methods of investigation included light and electron microscopy, morphometric analysis and statistical analysis. Acute exposure to +Gz loads resulted in essentially reactive changes in the centers under study. At the same time, regular exposure to this extreme factor led to cumulation of destructive changes. The peculiar structure of the centers governs uniqueness of disorders which may unbalance the autonomous regulation of organism functions.
