利用激光多普勒血流计和检测血纤维蛋白原浓度的方法来观察BX对豚鼠耳蜗血流的影响。取体重400～600g的健康成年豚鼠进行实验。第一种实验分三组:1组12只经颈静脉注入BX每ml含10单位(BU)的0.45mol/L氯化钠溶液,剂量1ml/kg,血流计探头置于耳蜗底转的侧壁上,同时由连接在颈动脉上的压力 The effects of BX on cochlear blood flow in guinea pigs were observed using laser Doppler flowmetry and fibrinogen concentrations. Take healthy adult guinea pigs weighing 400 ~ 600g for experiments. The first experiment divided into three groups: a group of 12 via the jugular vein injection of BX per ml with 10 units (BU) of 0.45mol / L sodium chloride solution, the dose of 1ml / kg, hemodynamic probe placed in the bottom of the cochlea Side wall, at the same time by the pressure connected to the carotid artery
