Anticoagulant therapy (1) Heparin: Heparin is a commonly used anticoagulant and is a highly sulfated glucosaminoglycan. Heparin is widely found in mammalian tissues, and mast cells are the main producing sites. The main sources of medicinal heparin are bovine lung and pig intestinal mucosa. Heparin used clinically is called unfraction heparin (UFH) because it is a mixture of components with different relative molecular weights. The relative molecular weight is between 33,000 and 30,000, which is also called standard heparin (SH). The drug name is heparin sodium. (2) Low molecular weight heparin: crude heparin is cracked into some fraction with relative molecular mass of 1000 ~ 12000 by chemical or enzymatic hydrolysis methods, and then purified. There are at least 10 kinds of low molecular weight heparin prepared by different manufacturers and different methods.2. The other is to configure various parameters in mainfest according to application scenarios to minimize activity anomalies caused by configuration parameters;有这工夫，我回去再背一段书不好？说完。相公你离他远点。This is very understandable.
