Abstract

|
Objectives : The aims of this study were to evaluate whether gastric contractility could be measured by bowel sound of rats, and whether gastrointestinal side effect of any herbal restoratives would be related with their inhibition of gastric contraction.
Methods : Streptozotocin (STZ)-induced diabetic rats were used as a gastric hypocontraction model. At the time of 6 weeks after induction of diabetes, 2mL of normal saline (NS) and 2mL of extract solution each containing 125mg/kg of Bojoongikki-tang (BJ), Sipjeondaebo-tang (SJ), Youngkaechulgam-tang (YG) were given to Normal (NR) and diabetic rats (DR), respectively. Bowel sound was recorded for 30 minute in fasting, and 120 minute of their administration. Gastric motility index was serially calculated with the ratio of accumulated potentials of post-administration/fasting state every 10 minutes.
Results : Gastric contractility between NR and DR could be significantly distinguished by bowel sound auscultation. BJ had a decreasing effect, SJ had a bidirectional effect, and YG had an increasing effect on gastric contractility measured by bowel sound auscultation.
Conclusions : BJ showed the possibility of inhibitory effects on gastric contraction. So, before administration, a gastric motility test should be recommended to prevent possible side effects in patients with gastric hypocontractility.
