myelin body 中文意思是什麼
myelin body
解釋
髓樣體-
The red blood cells of a normal person, for instance, age and die in 120 days. new blood cells are formed in bone marrow cells to ensure normal functioning of the human body. however, a vitamin b12 deficiency can make the red blood cells dysfunctional or prevent their successful formation, which in turn causes megaloblastic anemia anemia in which abnormally sized red blood cells are found in the blood. in some cases, prolonged vitamin b12 deficiency can deter the formation and functioning of myelin, subsequently leading to neuritis inflammation of the nerves or incomplete brain development
例如，人類正常的紅血球每120天便會老化死亡，所以骨髓細胞會持續產生新的紅血球，以維持人類正常之身體功能，所以如果缺乏維他命b12 ，便容易造成紅血球生合成功能不全，進而導致巨大型紅血球貧血megaloblastic anemia又例如，因長期缺乏維他命b12 ，會造成神經髓鞘myelin生合成功能不全，進而導致神經炎及腦部發育不全等等。
