EXPERIMENTAL RESEARCH Differences in Effects of Zuojin Pills (左金丸) and Its Similar Formulas on Wei Cold Model in Rats

Objective: To explore the effects of Zuojin Pills (左金丸) and its similar formulas on the stomach To explore the effects of Zuojin Pills (左金丸) and its similar formulas on the stomach cold syndrome in a Wei cold model in rats. cold syndrome in a Wei cold model in rats. Methods: The rat Wei cold model was established by intragastric The rat Wei cold model was established by intragastric administration of glacial NaOH, and the gastric mucosa injury indices, together with the levels of motilin and administration of glacial NaOH, and the gastric mucosa injury indices, together with the levels of motilin and gastrin in the stomach, were determined. The preventive and curative effects of Zuojin Pills and its similar gastrin in the stomach, were determined. The preventive and curative effects of Zuojin Pills and its similar formulas on gastric mucosa injury were investigated. formulas on gastric mucosa injury were investigated. Results: Zuojin Pills and its similar formulas could protect Zuojin Pills and its similar formulas could protect the gastric mucosa in the gastric cold model in rats at different levels. Fanzuojin Pills (反左金丸) had the best the gastric mucosa in the gastric cold model in rats at different levels. Fanzuojin Pills (反左金丸) had the best effect in inhibiting gastric mucosa injury. effect in inhibiting gastric mucosa injury. Conclusion: The different pharmacological effects of Zuojin Pills and The different pharmacological effects of Zuojin Pills and its similar formulas in the rat gastric cold model were partially correlated with the degrees in cold and heat its similar formulas in the rat gastric cold model were partially correlated with the degrees in cold and heat properties of the formulas. properties of the formulas.
