在人体内,维持正常的渗透压平衡,乃是保证各种物质代谢过程以及组织和器官的机能活动得以正常进行的内环境恒定的重要条件之一。了解人体内的渗透压平衡变化的规律,测定各种体液,如血清或血浆、胃液、脑脊液以及尿液、汗液等排泄物的渗透压,对于一些疾病的病因研究、诊断和鉴别诊断以及预防和治疗,都有着积极的意义。渗透压的测定方法-冰点下降法渗透压的测定可用半透膜的直接测定方法(见图1)和不使用半透膜的间接测定方法两大类。由于在人体的各种体液中除蛋白质
Maintaining a normal osmotic pressure balance in the human body is one of the most important conditions for assuring a constant internal environment for the functional metabolism of various substances and for the normal functioning of tissues and organs. Understand the law of osmotic pressure balance change in the human body, determine the osmotic pressure of various body fluids such as serum or plasma, gastric juice, cerebrospinal fluid and urine, sweat and other excretions, for the etiological research, diagnosis and differential diagnosis of some diseases and for prevention and Treatment, have a positive meaning. Determination of osmotic pressure - freezing point method for the determination of osmotic pressure can be used semi-permeable membrane direct determination of the membrane (see Figure 1) and does not use the semi-permeable membrane indirect determination of two major categories. Because of the body in a variety of body fluids in addition to protein
