有些学者认为,尘肺是一种不可逆性的、以肺部纤维化为主的疾病。对于它的治愈有的人似乎已无信心。临床上采用药物治疗主要是改善患者的症状,延缓进期,从而达到延长寿命的目的。目前,在一些国家对于尘肺防治药物的研究持消极态度,而苏联学者近年来仍坚持防治药物的研究,努力寻找新的有效的防治药物。他们研究的特点是:(1)研究合成新的药物,(2)改造原有尘肺防治药物的化学结构,(2)进一步研究某些
Some scholars believe that pneumoconiosis is an irreversible disease based on pulmonary fibrosis. There seems to be no confidence in the healing of it. The clinical use of drug treatment is mainly to improve the patient’s symptoms, delaying the progress, so as to achieve the purpose of prolonging life expectancy. At present, the research on pneumoconiosis prevention and treatment in some countries holds a negative attitude. However, the Soviet scholars insist on the prevention and treatment of drugs in recent years and try hard to find new effective prevention and treatment drugs. Their research features are: (1) to study the synthesis of new drugs, (2) to modify the chemical structure of the original pneumoconiosis prevention and treatment drugs, (2) to further study some
