感觉神经性听力减退是中耳炎最常见的并发症，其发生机制尚不清楚。很多研究发现国自膜能渗透内毒素等物质进入内耳，影响内耳功能。但研究者都是在回窗膜正常情况下实验的结论，对于中耳炎后国富膜对内毒素渗透性如何很少研究。为探索这一论点，以豚鼠为实验对象，用纯大肠杆 Sensory neurological hearing loss is the most common complication of otitis media, the mechanism is not yet clear. Many studies found that the membrane from the membrane into the inner ear, endotoxin and other substances, affecting the inner ear function. However, researchers are in the normal case of window film back to the conclusion of the experiment, how to membrane permeability of endophthalmitis after otitis media how little research. To explore this argument, guinea pigs as the experimental object, with pure large intestine
