| overview | gastric membrane element, which means gastric mucosa regeneration. The gastrin extracted from the gastric mucosa of pigs is white to yellow-white powder or yellow-brown particles, with a peptone smell, a slightly salty taste, and the water rises into a slime, which is slightly soluble, and the aqueous solution is gray or milky white. It precipitates when it is weak acid, does not solidify when it is heated, and can be precipitated by more than 60% ethanol or acetone in the solution. With acid for a long time, can be decomposed into a variety of protein and polysaccharide components, the polysaccharide components contain glucuronic acid, mannose, acetylglucosamine and acetylgalactose, the total amount of hexosamine is 5~8%,PI3.3~5. my country is extremely rich in raw materials for pig stomach, but the process of extracting gastrin from pig gastric mucosa is relatively backward. In China, it is mainly produced according to the process route of gastric mucosal digestion, trichloromethane or ether degreasing, acetone precipitation, and drying. The process takes a long time and the yield of gastrin is low, only about 1.5%; foreign countries adopt pH6.5 NaH3PO4, EDTA, NEM and guanidine hydrochloride buffer as the extract, after high-speed centrifugation, dialysis, and equal density gradient centrifugation, the process is complex, the production cost is high, the production cycle is long, the ethanol extraction method is used to improve the yield of gastric membrane, the production cost is low, and the extraction ethanol concentration is strictly controlled, Processing time and temperature to improve product quality. |
| application | gastric membrane is a mucin prepared by digestion and extraction of pig gastric mucous membrane. it has anti-pepsin decomposition and weak anti-acid effect, can form a membrane in the stomach, cover the ulcer surface, reduce the stimulation of gastric acid, and is conducive to the healing of the ulcer surface, it can also reduce the pain of patients. Gastrin can activate the regenerative DNA replication chain of gastric mucosal cells, so that the gastric mucosa can quickly generate new tissues. In addition, it has anti-pepsin decomposition and weak antacid effects, forming a membrane in the stomach, covering the ulcer surface, and reducing the stimulation of gastric acid. Conducive to the healing of the ulcer surface; clinically used to treat gastric, duodenal ulcer and hyperacidity. |
| biological activity | Gastrin I, human is an endogenous peptide produced in the stomach, which increases the secretion of gastric acid through the CCK2 receptor. |
| target | CCK2 receptor |
| in vitro study | Gastrin I, human is the endogenous peptide produced in the stomach, and acts via cholecystokinin 2 (CCK2) receptor. |
| in vivo study | Gastrin I (1.5, 5, 15 and 45 nmol/kg, I. v.) increases pepsinogen and acid secretion in rats. |
| chemical properties | light yellow or light gray powder, or tiny particles. The water swells into sticky slurry. Microlytic state, slightly peptone-like odor. Has a strong adhesion. |
| use | the product is adhered to the inner wall of the stomach after taking it, forming a protective film on the ulcer wound surface, reducing the stimulation of gastric acid on the ulcer surface, preventing it from being corroded by gastric acid and gastric enzymes, thus achieving the purpose of healing the wound. Can be used for stomach, duodenal ulcer and hyperacidity. |
| production method | gastric membrane sediment obtained by separating pepsin production is extruded into water, tore and washed fully with 2 times of cold acetone, let stand for 24 hours, and pour out acetone. Wash with cold acetone once, pour out acetone after 24 hours, fully stir with 2 times the amount of fresh acetone, soak for 48 hours, pour out acetone, squeeze dry, and obtain gastric membrane hormone wet product. Dry the wet product with water content not exceeding 5%, crush it with a ball mill and sift it with 60 mesh to obtain gastrin. For gastric viscosity meter, the total yield is 1.2-1.5%. |
