ABSTRACT
CONTEXT Valerian extract capsule (VEC) is an effective Chinese patent medicine used for gastrointestinal (GI) diseases. OBJECTIVE:
To investigate the detailed pharmacological activity for VEC clinical effects in GI diseases. MATERIALS ANDMETHODS:
Sprague-Dawley rats were divided into six groups control, model, and drug-treated (VEC-L, VEC-M, VEC-H, and teprenone). Rats were orally administered VEC (124, 248, 496 mg/kg) and teprenone (21.43 mg/kg) for 3 consecutive days. After 1 h, the five groups (except the control group) were orally given ethanol (10 mL/kg) for 1 h or indomethacin (80 mg/kg) for 7 h. The spasmolytic activity of VEC (0.01-1 mg/mL) on ACh/BaCl2-induced New Zealand rabbit smooth muscle contraction was performed. The C57BL/6 mice carbon propelling test evaluated the effects of VEC (248-992 mg/kg) on intestinal motility in normal and neostigmine/adrenaline-induced mice.RESULTS:
Compared with the model group, VEC treatment reduced the gastric lesion index and mucosal damage. Further experiments showed that the pathological ameliorative effect of VEC was accompanied by augmentation of the enzymatic antioxidant system and cytoprotective marker (COX-1, p < 0.01; PGI2 p < 0.05;), along with the alleviation of the levels of MPO (ethanol 15.56 ± 0.82 vs. 12.15 ± 2.60, p < 0.01; indomethacin 9.65 ± 3.06 vs. 6.36 ± 2.43, p < 0.05), MDA (ethanol 1.66 ± 0.44 vs. 0.81 ± 0.58, p < 0.01; indomethacin 1.71 ± 0.87 vs. 1.09 ± 0.43, p < 0.05), and inflammatory mediators. VEC decreased the high tone induced by ACh/BaCl2 and promoted intestinal transit in normal and neostigmine/adrenaline-induced mice. DISCUSSION ANDCONCLUSIONS:
VEC showed a potential gastroprotective effect, suggesting that VEC is a promising phytomedicine for the treatment of GI diseases.Palavras-chave
