Human body defence mechanisms

Respirable particulates Particulates in the size range that can pass through the defence mechanisms in the human body and enter the lungs during inhalation. 

The progression of human immunodeficiency virus (HIV) towards its more advanced stages is accompanied by increasing body stores of iron. Iron accumulates in macrophages as well as microglia, endothelial cells and myocytes. The iron burden is especially intense in the bone marrow, brain white matter, muscle and liver. Such excesses of iron will enhance oxidative stress, impair several already compromised immune defence mechanisms and directly promote the growth of microbes (Boelaert et ah, 1996). 

Benefits Ginseng s main action is to help the body fight off physical, chemical and biological attacks by raising the body s own defence mechanisms. In human studies, there was a visible benefit in terms of physical and mental performance. It was also shown to reduce blood sugar levels in Type II diabetics. 

The word arthritis simply means inflammation of the joints and the disease has been recognised as an affliction of the human condition since early times. The Hindus of India wrote about it as long ago as 1000 BC, and Hippocrates in ancient Greece believed it to be a symptom of poisoning which could be relieved by blood letting. A hundred years ago doctors thought it was caused by an infection and one way to treat it was to remove sources of infection from the body, such as teeth, tonsils, and appendix. Today we regard arthritis as an autoimmune disease in which the body s defence mechanism has turned upon itself.
