高原环境(海拔2950米以上)对豚鼠耳蜗有一定不良影响,其组织形态学有不同改变,这种改变,海拔越高,改变越重。但不随居住时间延长而加重。经实地电测正常人耳,不同海拔高度有不同程度感音性听力减退,其改变情况与动物实验基本相符。以中药草红花作了预防耳蜗受影响试验观察结果:草红花对提高整个机体在高原适应能力方面有一定作用,但对高原环境影响耳蜗局部改变方面尚无明显效果。
High altitude environment (2950 meters above sea level) on the guinea pig cochlea have some adverse effects, the histological changes have different, this change, the higher the altitude, the more severe changes. But do not increase with the extension of living time. After the field test normal human ear, different degrees of altitude have sensory hearing loss, the change is basically consistent with animal experiments. Chinese herbal medicine safflower made to prevent cochlear affected by the test results observed: safflower to improve the ability of the whole body to adapt to the plateau has a certain effect, but no significant effect on local environmental changes of the cochlea.
