钡广泛存在于自然界,随着工业发展,其被应用于很多领域。有研究表明,可溶性钡盐对机体有较强毒性,不溶性钡盐在胃内受胃酸作用可变成可溶性氯化钡而具有毒性。钡离子可作用于全身肌肉,引起肌肉的兴奋而后麻痹;可使机体多种酶发生改变;且有性腺毒和致畸等作用.本实验对经氯化钡染毒小鼠的免疫器官进行了病理组织学检查,旨在探讨氯化钡是否对免疫系统具有毒性作用。
Barium is widespread in nature and has been used in many fields as the industry develops. Studies have shown that soluble barium salt on the body has a strong toxicity, insoluble barium salt in the stomach by the role of gastric acid can become soluble barium chloride and toxic. Barium ions can be applied to the body muscles, causing muscle excitability and paralysis; can make a variety of enzymes in the body to change; and sexual gonadal toxicity and teratogenic and other effects.In this experiment on mice exposed to barium chloride immune organs were Histopathological examination is to investigate whether barium chloride has a toxic effect on the immune system.
