Abstract

To explore the effect of monosialotetrahexosylganglioside sodium on cortical neurogenesis in traumatic brain injury rats. Thirty Sprague–Dawley rats were randomly divided into the control group, the saline group and the monosialotetrahexosylganglioside sodium group. The rats traumatic brain injury model of saline group and the monosialotetrahexosylganglioside sodium group, control group rats was prepared with hydraulic controllable injury device and control group received sham operation. The levels of oxidative stress, nerve damage, cortical new born neurons, learning and memory capabilities of rats were assessed with serum malondialdehyde and superoxide dismutase levels, serum neurofilament light level and terminal deoxynucleotidyl transferase dUTP nick end labeling, neuronal nuclear protein/ bromodeoxyuridine cells and Morris water maze respectively. Compared with the control group, the level of oxidative stress was significantly increased, the nerve damage was obvious, the number of new born neurons increased, and the ability of learning and memory decreased in the other two groups. Compared with the normal saline group, the oxidative stress level was lower, the nerve damage was reduced, the number of new born neurons increases more obviously and the decline in learning and memory ability was reduced in the monosialotetrahexosylganglioside sodium group. Monosialotetrahexosylganglioside sodium can reduce the oxidative stress level, protect the nerve cells from damage and promote the neurogenesis in the cortex and promote the improvement of cognitive functions such as learning and memory in traumatic brain injury rats.
