五肽胃泌素是消化道激素,由17个氨基酸组成的多肽类,主要是促进胃液或胰酶的分泌。按其化学结构特征在第12位上酪氨酸有无硫酸酯而分成甲、乙两种。不带有硫酸酯基团的称为甲型,而带硫酸酯基团为乙型,两者具有同等生物活性及免疫活性。我院配制五肽胃泌素注射液原料为人工合成的白色粉末(上海生物制品研究所供应),难溶于水,溶于碱性溶液。取五肽胃泌素粉剂1 mg 徐徐加入灭菌蒸馏水中(溶液用
The pentagastrin is a digestive tract hormone consisting of 17 amino acids, which mainly promotes the secretion of gastric juice or trypsin. According to its chemical structure characteristics, there is no sulphate in the 12th position and there are two kinds of A and B. The non-sulfate group is called A-type, while the sulfate group is B-type. Both have the same biological activity and immunological activity. The preparation of pentagastrin injection in our hospital is made of synthetic white powder (supplied by Shanghai Institute of Biological Products), which is hardly soluble in water and soluble in alkaline solution. Take pentagastrin powder 1 mg slowly added to sterile distilled water (solution used
