【Abstract】 Objective: To study regulative action of mica monomer granule preparation on gastrin (GAS),somatostatin (SS) and G cells as well as D cells of gastric mucosa in experimental chronic atrophic gastritis (CAG) rat. Method: CAG rats were treated with mica monomer granule preparation with three different dosages-high,moderate and low level respectively. Changes of blood serum GAS,blood plasma SS and G cells as well as D cells of gastric mucosa in CAG rats were observed and detected with ELISA method,RIA method and immunocytochemistry method. Result: Mica monomer granule of three different dosages could increase the quantity of G cells as well as D cells of gastric mucosa and the concentration of blood serum GAS and decrease the content of blood plasma SS in CAG rat at different level respectively. It was more effictive in high and moderate dosage groups. Conclusion: Mica has the pharmacological action of protecting gastric mucosa,promoting the palingenesis of gastric gland and enhancing blood stream of gastric mucosa consequently to abate the inflammation reaction of gastric mucosa. Its effective mechanism is associated with the neuroendocrine regulative mechanism of promoting the secretion of gastric acid and gastric pepsin by increasing the amount of G cells as well as D cells and the concentration of blood serum GAS, and reducing inhibiting action on GAS secretion and enhancing the secretion of GAS by decreasing the content of SS.更多还原
