ABSTRACT
Objectives: Gardenia Jasminoides Ellis (Zhizi), belonging to Rubiaceae family, has been traditionally used for treatment cholestasis and jaundice for centuries in Asian countries. In the theory of Traditional Chinese Medicines, Zhizi could dispel dampness and heat via the urine to execute its choleretic effects. However, the potential molecular mechanism has been still poorly clarified. Here, we investigated the effect of different dose of Zhizi aqueous extract powder (0.3 g/kg/d and 0.9 g/kg/d) on urinary excretion of bile acids (BAs), and defined the potential mechanism via renal BAs efflux transporters Mrp2 and Mrp4 in normal rats. Methods: Male Wistar rats were orally administrated with 0.3 or 0.9 g/kg/d dose of Zhizi aqueous extract powder for 2 weeks, then body weight, serum aminotransferase, total BAs concentrations in liver, bile, serum, kidney and urine, 1 h bile flow, 12-h urinary volume, biliary and urinary excretion amount of total BAs as well as protein expression of major renal BAs efflux transporter Mrp2 and Mrp4, were all evaluated. Results: Zhizi especially the high dose of Zhizi aqueous extract powder could reduce hepatic total BAs concentration. Additionally, bile flow and biliary excretion had no significant difference, but the remarkable increasing urinary excretion of BAs and 2 to 3 folds up-regulated renal Mrp2 expression were observed after administrated with Zhizi as compared with the control group. Conclusion: The findings indicate that Zhizi reduces hepatic total BAs level by increasing urinary excretion rather than the biliary excretion of BAs, which, in turn ascribed to elevated protein expression of Mrp2 at apical membrane of renal tubular epithelial cells.
ABSTRACT
This study was aimed to observe the antipyresis and cholagogue effect of theFructus Gardeniae-Fructus Forsythiaeherb couple in order to explore the possible pharmacodynamic mechanism. Dry yeast suspension was subcutaneously injected into the back of rat to establish the fever model. The freeze-dried powders ofF. Gardeniae,F. Forsythiae, andF. Gardeniae-F. Forsythiaeherb couple were prepared. They were dissolved in the water for intragastric administration. SD rats were randomly divided into the normal group, model group, positive control group and Chinese medicine group. The Chinese medicine group was subdivided into the group ofF. Gardeniae,F. Forsythiae, andF. Gardeniae-F. Forsythiaeherb couple. The concentration of herbal water extract was 10 mL·kg-1 (which equaled to 3 g·kg-1 of a single crude herb). The concentration of positive control was 10 mL·kg-1. Intragastric administration of equal amount of normal saline was given to the blank group and the model group. Except rats in the normal group, rats in other groups were subcutaneously injected with 10 mL·kg-1 of 15% dry yeast suspension on the back of to establish the fever model. Electronic thermometer was used to record the body temperature of rats at 0, 1, 4, 5, 6, 7 and 8 h after the injection, respectively. Meanwhile, bile was collected from 1-1, 1-2, 2-4, 4-6, 6-8, 8-12, 12-24 h, respectively. Observation was given on changes of body temperature and bile amount of rat. The results showed thatF. Gardeniae,F. Forsythiae, andF. Gardeniae- F. Forsythiaeherb couple had certain effect to reduce the body temperature of rats. The temperature-reducing effect of the combination of both herbs was better than a single herb. TheF. Gardeniae -F. Forsythiae herb couple can reduce the body temperature of fever rat (P < 0.05, orP < 0.01). It had a little effect on the body temperature of normal rat. TheF. Gardeniae - F. Forsythiaeherb couple can promote the bile secretion, which was better than the single using of F. Gardeniae (P < 0.05). It was concluded that theF. Gardeniae - F. Forsythiaeherb couple had better temperature-reducing effect than the using of a single herb; however, there was no significant difference. But it had obvious effect on the promotion of bile secretion, which indicated the strengthening of cholagogue effect.
ABSTRACT
Objective To evaluate the clinical effect of ultrashort wave combined with dephlogisticate cholagogue table in treating patients with chronic cholecystitis.Methods One hundred and forty-four patients with chronic cholecystitis treated from January 2009 to October 2011 were randomly divided into 2gtoupe by mechanical sampling method.Treatment group (76 cases) was treated with ultrashort wave and dephlogisticate cholagogue table.Control group (68 cases) was treated with dephlogisticate cholagogue table.The therapeutic effect and the incidence of ache and fever and B-type ultrasonography between two groups were compared.Results The total effective rates were 89.5％ (68/76) in treatment group and 67.6％(46/68) in control group.There was significant difference (P ＜0.01).The incidence of ache and fever,positive rate of B-type ultrasonography in tneatment group [10.5％(8/76),5.3％(4/76),10.5％(8/76)] were significantly lower than those in control group [32.4％ (22/68),14.7％ (10/68),33.8％(23/68)] (P ＜ 0.05).Conclusion Ultrashort wave combined with dephlogisticate cholagogue tabble is an effective method for treating chronic cholecystitis.
ABSTRACT
OBJECTIVE:To optimize the extraction technics of liver-strengthening cholagogue oral preparation.METHODS:The effects of the four factors-the quantity of the added water,the decoction time,the decoction times and the alcohol precipitation concentration on the extraction results were determined with content of total flavonoids taken as index.RESULTS:The best extracting condition was the following,the amount of the added water was 10 times that of the medicinal materials,the decoction duration was 60min,the alcohol precipitation concentration was 50%and the decoction was carried out twice.CONCLUSION:The preparation under this technics is of high clarity and stable contents.
ABSTRACT
Objective To study the protective action of Shuganwan on liver injury and its cholagogue action. Methods Acute liver injury was induced by carbon tetrachloride in rats. The biochemical indexes and pathological changes were used for evaluation. The cholagogue action was studied by biliary drainage method. Results Compared with those of the CCl 4 control group, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and bilirubin levels of Shuganwan group declined significantly, and albumin/ globulin (A/G) inversion was obviously improved. The pathological changes revealed that liver injury was relieved. There was no change in bile secretion after administration of Shuganwan. Conclusion Shuganwan has protective action on acute liver injury by carbon tetrachloride, but no promotive action on bile secretion.
