Some pathogenetic aspects of experimental pneumococcal meningitis in acute period

Abstract

Morphological displays of cerebral microcirculation derangements in a brain cortex with their semiquantitative estimation have been studied in experimental mice model of the first 24-72 hours period of pneumococcal meningitis.Also displays oxidative stress and activity antioxidative protectional system by means of definition of markers of these processes – malondialdehide, reduced glutathione and glucose-6-phosphate-dehydrogenase activity have been investigated. The received results testify to morphological signs of the expressed derangements of cerebral microcirculation in a brain cortex already by first 24 hour of an experimental meningitis. The maximum expressiveness oxidative stress and activity antioxidative protectional system of reduced glutathione with the max activity of glucose-6-phosphatedehydrogenase in a mice brain cortex was noted at first 48hour durations of experimental disease. Signs of irreversible changes of mice cortex neurons are not revealed at 24–72-hour duration of experimental pneumococcal meningitis
