Carpal tunnel syndrome , ulna nerve neuritis , etc strokes and some vascular and neurological problem e . g . parkinson s disease , polio , multiple sclerosis , etc 心血管系统病症如中风偏瘫半身不遂呼吸系统病症如气管炎肺炎哮喘支气管扩张等脑部退化病症如柏金逊症手脚活动失控等物理治疗与药物治疗，里应外合，令复原事半功倍。
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，人类正常的红血球每120天便会老化死亡，所以骨髓细胞会持续产生新的红血球，以维持人类正常之身体功能，所以如果缺乏维他命b12 ，便容易造成红血球生合成功能不全，进而导致巨大型红血球贫血megaloblastic anemia又例如，因长期缺乏维他命b12 ，会造成神经髓鞘myelin生合成功能不全，进而导致神经炎及脑部发育不全等等。
