Abstract:
OBJECTIVE:To study the mechanism of Aurantii fructus immaturus(AFI)and its main active ingredients in pro-moting gastrointestinal motility of model rats with spleen deficiency. METHODS:170 rats were randomly divided into blank group (10 rats) and modeling group (160 rats),rats in modeling group was induced models with spleen deficiency by bitter cold diar-rhea+irregular diet. After modeling, rats were randomly divided into model group, naringin (NA) low-dose, medium-lose, high-dose groups(3.267,6.535,13.070 mg/mL),neohesperidin(NE)low-dose,medium-lose,high-dose groups(3.865,7.730, 15.460 mg/mL),synephrine(SY)low-dose,medium-lose,high-dose groups(0.252,0.504,1.008 mg/mL),compatibility groups with 3 monomer ingredients (NA-NE-SY) low-dose,medium-lose,high-dose and AFI water decoction low-dose,medium-lose, high-dose groups(0.104,0.208,0.416 g/mL,calculated by crude drug),ig,once a day,10 mL/kg,for 7 d. After the last admin-istration,gastrin (GAS) in serum,and acetylcholine (ACh),motilin (MTL),substance P (SP),vasoactive intestinal peptide (VIP)levels in plasma were detected. RESULTS:Compared with blank group,GAS level in serum and ACh,MTL,SP levels in plasma in model group were reduced(P<0.01),VIP level in plasma was increased(P<0.05). Compared with model group,ex-cept for the GAS level in serum showed no obvious change in NA high-dose group and SY doses groups,other medicine groups were obviously increased (P<0.05 or P<0.01);the ACh levels in serum were obviouly increased in NE high-dose group,SY high-dose group and AFI water decoction low-dose group(P<0.01). MTL levels in plasma were obviously increased in NE medi-um-dose,high-dose groups,SY high-dose group,compatibility low-dose,medium-dose groups and AFI water decoction medi-um-dose,high-lose groups (P<0.05);SP levels in plasma were obviously increased in NA low-dose,medium-dose groups and NE doses groups(P<0.05 or P<0.01);VIP levels were reduced in NA low-dose group,SY high-dose group and AFI water decoc-tion low-dose,medium-lose groups(P<0.05). CONCLUSIONS:AFI may promote the gastrointestinal motility of model rats with spleen deficiency by promoting the secretion of GAS,ACh,MTL,and inhibiting the secretion of VIP;there are differences be-tween AFI and the 3 monomer ingredients in regulation of gastrointestinal hormones.
