Abstract:
[Objective] To observe the regulatory effect of astragalosides (AST) on the binding capacity of gastrin receptor in gastric parietal cells (GPC) of rats with spleen deficiency. [Methods] SD rats were given gastric gavage of Radix et Rhizoma Rhei (Dahuang) decoction 10 g/kg to induce spleen deficiency. Gastric parietal cells were isolated and purified by Lewin gastric sac method and Percoll density gradient separation method. 2 mL suspension of GPC from rat models was incubated in vitro with AST 20 ?L at the concentrations of 10, 20 and 30 g/L respectively. Suspension of GPC from rat models incubated with phosphate buffered saline (PBS) served as the model group and suspension of GPC from the normal rats incubated with PBS as the normal group. The binding capacity of gastrin receptor in GPC was detected by radioligand receptor assay. [Results] The binding sites were 262.29?60.80 in the model group, much lower than 443.93?133.58 in the normal group (P
