Skin diseases caused by antimony and its compounds
Introduction
Introduction to skin diseases caused by bismuth and its compounds Physical and chemical properties: Sb is silver-gray metal, crisp and hard. The melting point of 630.5 ° C, the boiling point of 1380 ° C, the vapor of bismuth can be oxidized in the air into an oxide of bismuth; the alloy of bismuth can produce gas hydrogenated hydrogen (SbH3) in the presence of acid. basic knowledge The proportion of illness: 0.002% Susceptible people: no specific population Mode of infection: non-infectious complication:
Cause
The cause of skin diseases caused by bismuth and its compounds
(1) Causes of the disease
The mechanism of action of sputum on the skin is primary stimuli.
(two) pathogenesis
The mechanism of action of sputum on the skin is a primary stimuli. The systemic toxic effect may be due to the combination of strontium and sulfhydryl groups in the body, inhibiting the activity of sputum acid oxidase, thereby interfering with sugar metabolism or destroying the balance of electrolytes in the cells, thus causing Metabolic disorders and tissue damage in the body.
Prevention
Skin disease prevention caused by bismuth and its compounds
Strengthen personal protection, including wearing long rubber gloves, long boots, long aprons, protective glasses, masks, etc.
Complication
Dermatological complications caused by sputum and its compounds Complication
The toxic effects of earthworms and their compounds on the human body are mainly reproduced as spastic dermatitis, pneumoconiosis, liver and myocardial damage.
Symptom
Symptoms of skin diseases caused by bismuth and its compounds Common symptoms Rash
The bismuth compound is a poison that has multiple effects on the body. In addition to causing changes in hematopoiesis, respiration, nervous system and substance metabolism, it can also cause obvious irritation or even allergic reactions to the skin. It mainly occurs in exposed parts such as face, neck and upper limbs. It can reduce the content of cystine in hair and nails of production personnel. A 1% sodium citrate aqueous solution was used for the skin patch test. There is a positive.
Examine
Examination of skin diseases caused by bismuth and its compounds
The disease mainly occurs in exposed parts such as the face, neck and upper limbs, which can cause urticaria. A 1% sodium citrate aqueous solution had a positive rate of 2.2% for the skin patch test. In addition, it has been reported that cockroaches can reduce the content of cystine in the hair and nails of the production staff, and mention that the appearance of dark green moss on the tongue is a special manifestation of occupational poisoning, so the examination is mainly based on the characteristics of the rash and nails. Detection of cystine content. Secondly, sputum poisoning can lead to sputum destruction leading to hemolysis.
