Det används fortfarande, mot leukemi.
This medicine is used to treat acute promyelocytic leukemia (APL).
Bara som en sista utväg, där patienten redan är döende och bara vid akuta fall, ocb bara mot en sorts cancer, APL Googlade jag fram från flera ställen. Det är inget man ger hursomhelst.
Och så det viktigaste, varningen: There is a potential for serious side effects to an unborn child. Talk to your health care professional or pharmacist for more information. Do not breast-feed an infant while taking this medicine.

Dessutom; vad jag vet så är alla ämnen dödliga - om man använder för mycket av dom.
mercury = kvicksilver. Ett av ämnena i svinisvaccinet, som f.ö tar ca 90 år innan kvicksilvret bryts ner i människokroppen.
*Mercury is rarely found by itself in nature

The process for extracting mercury from its ores has not changed much since Aristotle first described it over 2,300 years ago.

Mercury is highly toxic to humans.
Exposure may come from inhalation, ingestion, or absorption through the skin. Of the three, inhalation of mercury vapor is the most dangerous. Short-term exposure to mercury vapor can produce weakness, chills, nausea, vomiting, diarrhea, and other symptoms within a few hours. Recovery is usually complete once the victim is removed from the source. Long-term exposure to mercury vapor produces shaking, irritability, insomnia, confusion, excessive salivation, and other debilitating effects.

In normal situations, most exposure to mercury comes from the ingestion of certain foods, such as fish, in which the mercury has accumulated at high levels. Although mercury is not absorbed in great quantities when passing through the human digestive system, ingestion over a long period of time has been shown to have cumulative effects.

Because mercury poses a serious health hazard, its use and release to the environment has come under increasingly tight restrictions.
In 1988, it was estimated that 24 million lb/yr (11 million kglyr) of mercury were released into the air, land, and water worldwide as the result of human activities. This included mercury released by mercury mining and refining, various manufacturing operations, the combustion of coal, the discarding of municipal refuse and sewage sludge, and other sources.
In the United States, the Environmental Protection Agency (EPA) has banned the use of mercury for many applications. The EPA has set a goal of reducing the level of mercury found in municipal refuse from 1.4 million Ib/yr (0.64 million kg/yr) in 1989 to 0.35 million lb/yr (0.16 million kg/yr) by 2000. This is to be accomplished by decreasing the use of mercury in products and increasing the diversion of mercury from municipal refuse through recycling.

The first use of a mercury alloy, or amalgam, as a tooth filling in dentistry was in 1828, although concerns over the toxic nature of mercury prevented the widespread use of this new technique. It wasn't until 1895 that experimental work by G.V. Black showed that amalgam fillings were safe, although 100 years later scientists were still debating that point.

Då jag inte har lust att debattera detta ämne i 100 år, får detta bli mitt absolut sista inlägg, kommer att bli svårt att stå emot dock.. ;)
