Au(CN)2] inhibits the oxidative burst of polymorphonuclear leukocytes and the proliferation of lymphocytes in vitro (both types of cells actively participate in the development and maintenance of inflammatory processes of rheumatoid disease) [71]. It is also far more toxic than gold(I) thiolates to bacteria, plants and animals. 

That the oxidative burst is directly involved in the chemical defense of these algae is clear. This reaction can be inhibited by diphenyleneiodonium, a suicide inhibitor of NADPH-oxidase which suppresses both the production of reactive oxygen species and the natural resistance to epiphytic bacteria. In addition a role in the defense against endophytes was indicated, since pre-treatment with oligomeric guluronates resulted in decreased infection of L. digitata with the pathogen Laminariocolax tomentosoides [141]. 

Botrytis cinerea is responsible for gray mold disease in more than 200 host plants. This necrotrophic fungus displays the capacity to kill host cells through the production of toxins and reactive oxygen species and the induction of a plant-produced oxidative burst. Thanks to an arsenal of degrading enzymes, B. cinerea is then able to feed on various plant tissues (Choquer and others 2007).

Effects of TCDD on macrophages have also been examined. When assessed ex vivo, macrophage functions such as tumor cell lysis, phagocytosis and oxidative burst were not suppressed by exposure to TCDD.9396 101 In other experimental systems, exposure to TCDD increases IL-1 and TNF production by macrophages.99 102 103 However, the ability of TCDD to alter IL-1 and TNF production is likely organ- or stimulus-specific, because in the context of respiratory viral infection, exposure to TCDD had no effect on IL-1 or TNF-a levels.80... 

A common metabolite found in the urine and plasma of patients treated with gold drugs is [Au(CN)2], an ion which readily enters cells and can inhibit the oxidative burst of white blood cells. It may therefore be an active metabolite of gold drugs. It also exhibits anticancer and anti-HIV activity. The high Au contents of red blood cells of smokers receiving gold therapy has been attributed to the inhalation of HCN in smoke (420).
