Skin diseases caused by selenium and its compounds

Introduction to skin diseases caused by selenium and its compounds Industrial application: Selenium and sulfur belong to the same period of elements, the chemical properties are similar to sulfur, selenium is easily volatilized into aerosol, and selenium dioxide (SeO2) can be formed in the air. Selenium is widely used in electrical appliances, rubber, glass, pottery, metallurgy. , pigments and other industries, also used in photovoltaic cells, photometers and selenium electrostatic copying. basic knowledge The proportion of illness: 0.003%--0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: physical skin disease

Causes of skin diseases caused by selenium and its compounds

First, the cause of the disease

The toxic effects of selenium. In addition to causing systemic acute or chronic poisoning, it also causes skin lesions.

Second, the pathogenesis

Almost all selenium salts act on the skin as a primary stimulus. Can cause skin mucous membrane burns, can also cause skin inflammatory reactions.

Prevention of skin diseases caused by selenium and its compounds

The most effective way to prevent selenium poisoning is to prevent people and animals from taking in selenium-enriched foods and feeds. The United States should take precautions to remove selenium-enriched pastures or replace pastures. Some livestock also have the ability to identify selenium-enriched pastures, as some selenium-enriched pastures give off a garlic odor.

In addition, the presence of sulfur in the soil will inhibit the absorption of selenium by plants. Therefore, some countries adopt measures such as applying gypsum or sulfur-containing fertilizers in pastures to reduce the selenium content of plants.

Shaanxi has adopted the method of changing grain in recent years, and has also received good results in preventing selenium poisoning in human body; vitamin E is a good antioxidant to prevent selenium poisoning; methionine can also prevent selenium poisoning, but there must be enough in the ration. Vitamin E.

Skin disease complications caused by selenium and its compounds Complications physical skin disease

Skin mucosal bleeding.

Symptoms of skin diseases caused by selenium and its compounds Common symptoms Acute pain and hair loss

The toxic effect of selenium is similar to that of arsenic. In addition to acute or chronic poisoning, it can cause skin lesions. Many selenides such as selenium oxychloride (SeOCl2) can cause skin mucosal burns, and selenium dioxide can also cause skin inflammation. Reaction, finger contact with oxidized selenium can cause local pain, local examination in addition to slight redness, no blistering, oozing, etc., after the redness and swelling subsided, the pain continued to exist, and finally caused the nail to fall off, there are reports that severe hair can cause hair loss.

Examination of skin diseases caused by selenium and its compounds

Urine routine: increased selenium content in urine. Normal value <199umol/L (0.15 mg/L).

Blood routine: Learn to increase selenium. The normal value is 121.9 ± 40.5 g / L.

Diagnostic identification of skin diseases caused by selenium and its compounds

Long-term living in high selenium areas, eating food or poultry meat with high selenium content. Nail loss, redness and other symptoms of selenium poisoning. Both urine selenium and blood selenium are elevated. According to the above clinical manifestations and examinations can be diagnosed.
