盖膜的化学成份是有巨大争议的问题,对其功能亦如此。它是靠惰性使静纤毛触之变弯的被动性胶冻状、软糊状物,抑或完全主动地参予转递过程?近来所得证据提示其主要作用属机械性,但它紧邻螺旋器,想必能以调节化学物质进入盖膜下间隙的方式而影响毛细胞尖端的显微环境。作者为确定盖膜内蛋白质的化学物质,用豚鼠作了一系列实验,本文中仅提供简要的大体结果而未报道技术细节。 The chemical composition of the cover film is a matter of great controversy, as is its function. Is it inert passively jelly-like, mushy, or fully active participation in the transfer process by inertia? The recent evidence suggests that its primary effect is mechanical but close to the screw, Presumably to regulate the chemical substances into the gap under the membrane way to affect the micro-environment of the tip of hair cells. The authors made a series of experiments with guinea pigs to determine the chemical substance in the membrane of the capillaries, and only a brief summary of the results was provided in this paper without reporting technical details.
