Abstract

Objectives : The purpose of this study was to examine the effects of herbal medicines on pacemaker potentials of large intestinal interstitial Cells of Cajal (ICC) in mice. Methods : We made the ICC culture in large intestine in mice and used the electrophysiological method to record pacemaker potentials. Also we used MTT assay to check cell viability and examined the ICC protein expression by western blot. Results : 1.Glycyrrhiza uralensis Fischer (GF) (50-150 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC50 is 58.95 ㎍/ml. Angelica gigas (AG) (50-200 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC50 is 77.22 ㎍/ml. Poncirus fructus (PF) (10-100 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC50 is 13.39 ㎍/ml. Citrus unshiu S. Marcov. (CU) (10-500 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC50 is 139.80 ㎍/ml. Gardenia jasminoides J. Ellis (GJ) (100-500 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC50 is 78.70 ㎍/ml. Coptis chinensis (CC) (100-1000 ㎍/ml) induced pacemaker depolarization and decreased frequency with concentration-dependent manners. EC50 is 138.10 ㎍/ml. Scutellaria baicalensis (SB) (10-100 ㎍/ml) had no effects on pacemaker potentials and decreased frequency with concentration-dependent manners. IC50 is 18.34 ㎍/ml. Atractylodes macrocephala koidzumi (AM) (10-100 ㎍/ml) induced pacemaker hyperpolarizations and decreased frequency with concentration-dependent manners. IC50 is 18.54 ㎍/ml. 2. PF, SB and AM had no effects on cell death in large ICC. 3. PF increased the ANO1 and c-kit protein expression and SB and AM increased the c-kit protein expression in large ICC. Conclusions : These results suggest that PF, SB, and AM are likely to be the optimal combination of herbal medicines that can be used to treat diseases such as gastrointestinal motility disorders such as irritable bowel syndrome.
