ABSTRACT
OBJECTIVE To observe the changes of GABA and Glu in rat inferior colliculus following unilateral cochlear ablation and explore the function and significance of GABA and Glu in reorganization of auditory center after deafferentation. METHODS Twenty-five Sprangue Dawley (SD) rats were divided randomly into 5 groups. The content of GABA and Glu were measured by 835-50 type Amino Acid Automatism Analyzer and compared at 1 week, 2 week and 1 month after unilateral cochlear ablation respectively. RESULTS Compared with sham operated groups, the content levels of GABA decreased (from 78.00?7.50 to 51.65?10.36, about decreasing 33.6 %)1 week after unilateral cochlear ablation and there was a significant difference in GABA levels between 2 groups(P0.05). CONCLUSION The dynamic change of GABA and Glu in rat inferior colliculus reflected the neuronal activity, which implied both GABA and Glu may play an important role in reorganization of auditory center after unilateral cochlea ablation.
