3 Diagnostic principles

According to the exact history of occupational exposure, combined with clinical symptoms, signs and on-site hygiene survey data, comprehensive analysis, and Excluding other causes of similar diseases can be diagnosed. Urinary thallium content increased, can be used as exposure indicators.

4 Observation object

There are also poisoning patients do not occur hair loss. This standard provides Urine thallium test, can be used as a contact indicator can also be used as a reference for diagnosis. Other indicators of nerve - electromyography suggest nerve source Sexual damage.

A.4 treatment

Mainly to symptomatic support treatment, a large number of B vitamins, liver, kidney, heart and other organs. On the complexing agent should be with the problem, had tried sodium edetate, sodium dimercaptopropane, mercapto ethylamine, but there is no positive detoxification effect, it is not advocated so use.
