ABSTRACT
<p><b>OBJECTIVE</b>To explore an effective method for treating Gentamicin-induced deafness and the mechanism.</p><p><b>METHODS</b>Guinea pigs were randomly divided into 5 groups normal control group (group A), model group (group B), Ligustrazine group (group C), acupuncture group (group D) and Ligustrazine plus acupuncture group (group E). The group C, D and E were treated respectively by simple Ligustrazine, simple acupuncture at "Tinggong" (SI 19), "Yifeng" (TE 17), and "Waiguan" (TE 5), and Ligustrazine plus acupuncture. Ten days later, the auditory brainstem response (ABR) thresholds for the wave III , apoptosis and expressions of Bcl-2 and Bax proteins in the organ of Corti of the guinea pig were detected.</p><p><b>RESULTS</b>In the group E, the ABR threshold was significantly lower than that in the group C (P<0.05), and apoptotic cells, the expression of Bax protein and the ratio of Bax/Bcl-2 were lower than those in the group C and D in the organ of Corti, and Bcl-2 protein expression was increased.</p><p><b>CONCLUSION</b>Acupuncture at "Tinggong" (SI 19), "Yifeng" (TE 17), and "Waiguan" (TE 5) has a certain target-synergistic action on Ligustrazine and can increase therapeutic effect of Ligustrazine on Gentamicin-induced deafness, which are possible related with the inhibition of apoptosis, down-regulation of Bax expression and up-regulation of Bcl-2 expression.</p>
