[The effect of sodium 4',7-bihydroxylisoflavone-sulfonate on gastric motility and its mechanism in rat].

Aim: To explore the effect of sodium 4',7-bihydroxylisoflavone-sulfonate (SBIS) on gastric motility in rats and to analyse its mechanisms.

Methods: Using intraperitoneal (ip) injection and intracerebroventriular (icv) microinjection of drugs and recording the frequency and amplitude of contraction of gastric motility.

Results: (1) The injection (ip) of different doses of SBIS could decrease the amplitude of gastric motility, but it wasn't a dose-dependent effect.
