棉尘肺是一种职业性呼吸道疾病,常见于加工棉花、大麻和亚麻的工人中。其症状有胸部发紧并伴有通气量的降低。近年有研究表明如预服8毫克抗组织胺药物或1克抗坏血酸可使最大呼气流速的急速下降值显著减少。预服色甘酸钠(DSCG)30毫克,也可使最大呼气流速的急速下降值明显减少。由于纺织粉尘含有一种释放组织胺的活性物质,故接触粉尘所引起的呼气流速变化可通过口服小剂量抗组织胺药物来预防。色甘
Cotton pneumoconiosis is a form of occupational respiratory disease commonly found in workers who process cotton, hemp and linen. The symptoms are chest tightness accompanied by reduced ventilation. In recent years, studies have shown that pre-dose of 8 mg of antihistamine or 1 g of ascorbic acid can significantly reduce the rapid decline of the maximum expiratory flow rate. Preserved cromolyn sodium (DSCG) 30 mg, but also can make the maximum expiratory flow rate decreased rapidly decreased sharply. Since textile dust contains an active substance that releases histamine, changes in the expiratory flow rate caused by exposure to dust can be prevented by oral administration of small doses of antihistamine.
