简介:据说猫竖起的胡须长度和它的腰部宽窄完全相同,当追赶老鼠遇到狭窄的地方需要通过时,胡须就成了天然的尺子,可以迅速测量能否通过。无独有偶,我们人类的身体也有这种与生俱来的测量'本事',被称之为'生物尺',并作为尺寸单位沿用至今。比如,我们非常熟悉的'揸',指的是手指张开时拇指尖端和食指尖端的距离,长度约为15cm,还有'庹',是成人两臂左右伸直的长度。
简介:目前,我国因白内障致盲的人数约为400万到500万,在致盲眼病中,白内障仍占第一位,而老年白内障是最常见的白内障,是引起老年人失明的重要原因。蛋白质变性引发白内障白内障主要表现为视力下降和晶体混浊变白。起初稍有视物模糊,逐渐加重,最后也就只能分辨光亮而看不清东西了。早期晶状体纤维将经历水肿等一系列形态学变化,此时针对性地用药,可以逆转状况,近年来不手术治疗白内障已成为新的研究重点。从根本上阻止各种损伤因子对晶体蛋白质的攻击,也就成了治疗白内障的根本途径。国药'障福明',专清'变性蛋白质'治眼新药'障福明'(国药准字Z14020596),以纯正的天然珍珠层粉为主药,
