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。

Complete acid hydrolysis of the peptide followed by amino acid analysis yielded equimolar amounts of Leu, Orn, Phe, Pro, and Val. Orn is ornithine, an amino acid not present in proteins but present in some peptides .

此肽完全水解，然后经氨基酸分析产生等摩尔的Leu，Orn，Phe，Pro和Val，Orn为鸟氨酸，是蛋白质中不存在而存在于某些肽中的一种氨基酸。

A acute partial obstructive hepatocholangitis model by selective ligation and injection of E coli into left hepatic bile duct was successfully founded in rat. Using parameters including mortality, mitochondrial glutamic oxalacetic transaminase and ornithine carbamoytransferase activity, pathological observation and blood culture of bacteria, we evaluated the model.
