寿斑

“寿斑”衰老的象征

“寿斑”究竟是怎样形成的?对人体有无害处?这是许多老年人关心的问题。

老年性色素斑,是由脂褐色素构成的。它是人体细胞在代谢过程中,积累起来的有毒或无毒的废料,也可以说是细胞代谢过程中的高分子垃圾,因为它高度交联难以溶解,也无法通过细胞膜进入血液排出体外,结果,只能将细胞当作垃圾箱而不断堆积起来。它是稳定的代谢最终产物,并随着年龄的增长而增多,它可以遍布于人体的所有组织中,甚至在人的心肌纤维、脑、肝、肾上腺等重要器官的组织中,也有这种色素斑。它在皮肤上的出现率占老年人的27.6%。

表面上看来,色素斑对人的健康不大碍事,但科学研究的结果证明,它对人的健康有很大的影响,特别是对人类的脑细胞的影响很大。通常它好发于脑组织的海马回区域内,形成大小不一的球形。老年性神经官能症、智力障碍、健忘症、早老症或黑蒙家族性白痴等均与它有关系。因此,可以说老年性色素斑是造成脑功能不全的重要因素,也是衰老的象征之一。

老年性色素斑还会在体内其它处出现,有的人的肝、心、肺等内脏细胞表面有黑糊糊的一层脂褐色素沉积,影响细胞的正常生理功能,加速了细胞的老化,导致这些重要器官功能衰退降低。

那么,有没有办法控制色素斑的产生呢?科学家们研究发现,不少抗氧化剂,能阻断引起衰老的过氧化连锁反应,从而干扰褐色素的形成。在动物实验中,抗氧化剂(如维生素E、维生素C、硒、蛋氨酸等)有阻断褐色素的形成,而且可以延长寿命,逆转衰老的功能。

因此,老年人除生活有规律,调整好饮食,适当运动外,日常生活中加服天然的或人工合成的抗氧化剂(如每日服维生素E300毫克,维生素C300毫克),另外还可多吃含维生素E、C丰富的食物,如花生油、豆类、芝麻、海产品及绿色青菜等,也有助于干扰色素斑的形成,减轻老年性体衰,延缓衰老的进程。

治疗皮肤上的老年性色素斑,可用冷冻疗法,效果甚为满意。但不能用腐蚀剂或用手指抠剔,以防色素沉着的细胞角化变性。

Tongkat Ali is known to boost performance, stamina, and muscle mass in bodybuilding. In a clinical study conducted with a group of men, half the male was given Tongkat Ali to consume while the other half were not. During a few weeks of the physical training program, the men who consume the herbs experienced greater muscle mass gain, stamina, and strength. There were also a growing number of Asian athletes and bodybuilders whom are using Tongkat Ali as an androgen booster to improve muscle size and enhance their sports performance.

Testosterone is a male hormone that can be found in both men and women. But it is more of the male characteristics. Usually, at age 30, blood levels of testosterone start to decline slowly. If testosterone declines in a man’s body, his muscles, energy, and libido begin to decrease. Men who smoke and drink alcohol excessively lose testosterone faster than those who don’t. Male hormones or testosterone stimulates metabolism, promotes fat burning, increases red blood cells and muscle growth.
