自有人类社会时起,人们即在受伤时彼此实施救护,并力图防止外在因素对人体的危害。随着人们与疾病不断斗争的过程,对发病原因和治疗对策的认识逐步有了加深,逐渐积累了相当丰富的防治经验,因此,防和治成了人们向伤病作斗争的重要措施,并在经验积累的基础上逐步形成了医学科学。特别是十九世纪以来,由于化学、物理学、生物学、微生物学等科学的发展,更大大促进了医学的进步,使医学得以运用物理学与化学的方法来观察病理现象,防治疾病,因此,对人体与外界环境的关系、病因、病原机制以及诊断治疗等问题均有了较深的理解,为广泛地预防
From the time of human society, people are rushing to rescue each other when they are injured and try to prevent external factors from harming the human body. As people continue to struggle with disease, their understanding of the causes and treatment strategies has gradually deepened, and they have gradually accumulated a wealth of experience in prevention and treatment. Therefore, prevention and treatment have become important measures for people to fight injuries and illnesses, and Based on the accumulation of experience, medical science has gradually been formed. Especially since the 19th century, due to the development of sciences such as chemistry, physics, biology, and microbiology, greater progress has been made in medicine, and medicine has been able to use physical and chemical methods to observe pathological phenomena and prevent disease. , has a deep understanding of the relationship between the human body and the external environment, the etiology, pathogenic mechanism, and diagnosis and treatment, and is widely used for prevention.
