腋臭又称狐臭,是一种发生于腋窝部的特殊臭味。人体皮肤内有两种汗腺,一种叫小汗腺,分布于身体各处,另一种叫大汗腺,只在腋窝、乳头周围、阴部、肛围等处存在。大汗腺较大,所分泌的是一种乳白色或黄褐色糊状或胶状物,与小汗腺分泌的清亮的普通汗液不同。它除了具有普通汗液所有的内容外,还具有较多的游离脂肪酸、氨和羟酸;这些东西分解蒸发出来一种臭味,过去二,三十年,一直认为这是产生腋臭的原因。究竟是不是这样呢?近十年来,一些科学家做了一些新的研究和实验。从腋窝部取得纯粹的大汗腺,发现它是无 Bad smell, also known as body odor, is a special odor that occurs in the armpits. There are two kinds of sweat glands in the human skin, one is called the eccrine gland, distributed in various parts of the body, and the other is called the apocrine gland. It exists only in the armpit, the nipple, the pudendal area, and the anal area. The large apocrine glands secrete a milky or tanish paste or jelly that is different from the clear, sweaty secretions secreted by the eccrine glands. In addition to having all the contents of ordinary sweat, it also has more free fatty acids, ammonia and hydroxy acids; these things decompose and evaporate out of an odor, which has been considered to be the cause of underarm odor in the past two or three decades. Is this not the case? In the past decade, some scientists have done some new research and experiments. Pure apocrine glands were obtained from armpits and found to be without
