注射用结晶糜胰蛋白酶(Chymotrypsinum et trypsinum pro injectione)为从猪胰中提取制得的蛋白水解酶,它对手术或外伤后的炎性水肿、血肿、炎性粘连、血栓、溃疡以及稀释痰液等方面有较好的疗效。1978年,江苏吴县制药厂又将结晶糜胰蛋白酶的结晶或重结晶母液及0.65饱和度硫酸铵沉淀部分提取创制成口服用糜胰蛋白酶,并将其制成糜胰蛋白酶肠溶薄膜片。经凝胶电泳分析,口服用糜胰蛋白酶主要含糜蛋白酶、α与β胰蛋白酶及少量蛋白质的降解产物。因此,口服用糜胰蛋白 Chymotrypsinum et trypsinum pro injectione is a proteolytic enzyme extracted from porcine pancreas. It has been shown to inhibit inflammatory edema after surgery or trauma, hematoma, inflammatory adhesions, thrombosis, ulceration, and sputum excretion And so has a good effect. In 1978, Wuxian Pharmaceutical Factory in turn crystallized or recrystallized crystallization of trypsin crystallization of mother liquor and 0.65 saturated ammonium sulfate precipitation part of the creation of oral administration of trypsin and made it into trypsin enteric coated film. By gel electrophoresis analysis, oral trypsin mainly contains chymotrypsin, α and β trypsin and a small amount of protein degradation products. Therefore, oral administration of minced trypsin
