Now we don't know how aminoglycoside antibiotics damages hair cells, but there are some theories about it, such as:(1)AmAn affects the transformation among phosphoinositoln, inositol- 3-phophate and glycerine-2-acyl, also, it can cause the change of Ca2+ concentration in endocellular.

氨基糖甙类抗生素(aminoglycoside antibiotics， AmAn)损伤毛细胞的机制尚不清楚，但有以下几种学说：(1)影响了磷酸肌醇、三磷酸肌醇、二脂酰甘油间转化从而导致细胞内钙离子浓度的变化；(2)抑制G蛋白和鸟氨酸脱羧酶活性；(3)氨基糖甙类抗生素能引起内耳毛细胞的凋亡。

China rich Blueberry anthocyanins, Blueberry anthocyanins material in the pigment, anthocyanin mainly-2-glucosidase, anthocyanins-3-xylosidase, anthocyanins-3-Fu-glucoside, flowers Green-2-rhamnoside, D.-3-rhamnoside, D.-5-glucosidase, 3-o-original flower-Chui, Malvaceae pigment 3, 5-and two glucosidation 3, 3-such as stripping the original flower.
