外源性神经节苷脂对脑损伤的保护作用
AIM: To investigate protection function of ectogenesis ganglioside (GM1)to brain injury of epilepsy rats. METHODS: Inducing rat epilepsy model with sulfo-semicarbazide(7.5mg/kg), dynamically observe nerve growth factor (NGF) expression of epilepsy group and GM1 intervention group in Hippocampus and cerebral cortex nerve cell 24 h, 48 h, 72 h and 7 d after epileptic attack and control group after 72 h with immunohistochemistry method. At same time we observed change of nerve cell shape and structure with electron microscope techniques. RESULTS: Electron microscope showed nerve cell injury of epilepsy rats but injury relieved after GM1 intervention. CONCLUSION: GM1 play some protective function to brain injury of epilepsy rats through induced NGF expression increase.

Objective:To explore the effect and mechanism of ganglioside for hypoxia injury in newborn.Methods:A total of 200 cases of newborn patients in our hospital were analyzed. All the patients were divided into 4 groups, control and ganglioside groups with low, medium and high dose. The neonatal behavioral neurological assessment scores were counted in each group and the serum inflammatory factors and transforming growth factor-β (TGFβ)/Smad parameters were detected.Results:The neonatal behavioral neurological assessment scores were increased after ganglioside treatment and the serum interleukin (IL) 2/10, hypoxia inducible factorαand Smad1, Smad3 as well as TGFβ was decreased dramatically when compared with control group.Conclusions:Ganglioside exerts an effective effect on cerebral hypoxia in newborn mainly by inhibiting the TGFβ/Smad signaling pathway.
