(A) choose to collect raw materials Heparin exists in various tissues of livestock, including bovine lungs, Xuchang mucus mucus containing the highest heparin, the most easy to take digestion. Pig intestinal mucus, bovine lung is the best reason for the raw material of heparin physiology, based on tissue, intestinal mucosa, pulmonary blisters is the contact surface of the absorption of foreign objects, where most need to guard against defensive, so in the intestinal mucosal villi There is a layer of mucosa on the mucosa, submucosa connective tissue contains many of the manufacture of heparin mast cells, but also a good material for the extraction of heparin. Although a small amount of hepatic wall intestinal muscle, but for the reduction
