现代科学研究表明;人体出现退行性变化主要是体内产生的大量过剩自由基即活性氧自由基及其衍生物堆积造成的.许多外界因素都可以诱发自由基.如生物体内某些病理或生理过程中的生化反应等等.人的衰老受自由基的影响主要是因为自由基的化学发光强度升高,造成脂褐素含量增加和蛋白质含量下降.脂褐素含量增加是衰老的重要标志.脂褐素的聚积会干扰细胞的正常活动,使头脑反应迟顿,手脚运动不灵,面部皮肤色素沉着,进而全身出现衰老症状;过剩自由基会攻击核酸,导致核酸结构发生变化,影响机体蛋白质台成,使人体功能出现紊乱;人体内有一种纤维状结构的胶原蛋白,存在于人的皮肤及血管壁中,对美容及健康至关重要.当人体内自由基大量过剩时.引起胶原蛋白高联度增加,皮肤起皱,血管变脆,眼晶状体发生变化,从而引起冠心病、高血压、脑血栓、脑溢血、白内障等疾病.
Modern scientific research shows that the degenerative changes in the human body are mainly caused by the accumulation of a large number of excess free radicals in the body, ie, reactive oxygen radicals and their derivatives. Many external factors can induce free radicals, such as certain pathological or physiological processes in vivo. In the biochemical reactions, etc.. People’s aging is affected by free radicals is mainly due to increased free radicals chemiluminescence intensity, resulting in increased lipofuscin content and protein content decreased. Increased lipofuscin content is an important indicator of aging. Accumulation of brown pigment interferes with normal cellular activity, delays the reaction of the brain, impairs the movements of the hands and feet, pigmentation of the facial skin, and causes symptoms of systemic aging; excess free radicals attack the nucleic acid, resulting in changes in the nucleic acid structure and affecting the body’s protein platform. As a result, the function of the human body becomes disordered; in the human body there is a fibrous structure of collagen, which is present in human skin and blood vessel walls and is essential for beauty and health. When a large excess of free radicals in the human body causes collagen to be high Increased degree of connection, skin wrinkling, blood vessels become brittle, and changes in the lens of the eye, causing coronary heart disease, hypertension, cerebral thrombosis, cerebral overflow , Cataracts and other diseases.
