Effects of traditional Chinese medicine Zuojin Pill on gastrointestinal system / 药物评价研究

Objective To study the effects of traditional Chinese medicine Zuojin Pill on gastrointestinal system.Methods Through ig giving 0.1％ methyl orange solution,the gastric residual rate was calculated,and the effect of Zuojin Pill on gastric emptying in mice was observed.By ig administration of 5％ carbon powder,the advance rate of carbon powder was calculated,and the effect of Zuojin Pill on intestinal motility in normal mice and the antagonistic effect on intestinal motility hyperfunction induced by neostigmine were observed.Effect of Zuojin Pill on contraction of isolated guinea pig ileum induced by histamine was observed.After D-xylose solution was ig given to rats,the serum xylose level was determined 1 h later,and the effect of Zuojin Pill on rat intestinal absorption was observed.The anti-diarrhea effect of Zuojin Pill was observed by giving castor oil to mice.At the same time,we have made a comparison between Zuojin Pill and Wuji Pill-berberine,to evaluate the rationalization of Zuojin Pill.Results It was obvious in experimental results that Zuojin Pill had a regulating effect on gastrointestinal system.Zuojin Pill dose-dependently inhibited the gastric emptying.Zuojin Pill demonstrated more effective suppression on the accelerated movement induced by neostigmine,but did not inhibit normal intestinal transit in mice.Zuojin Pill markedly inhibited sperm motility in mice.Zuojin Pill concentration-dependently inhibited the contraction intensity of isolated ileum muscles in guinea pigs induced by histamine.Zuojin Pill markedly inhibited diarrhea induced by castor oil.Compared with Wuji Pill-berberine,the effect of Zuojin Pill on gastrointestinal system was more visible in the same dose.Conclusion Zuojin Pill has obvious regulation effect on the gastrointestinal tract,there are indications that the application of Zuojin Pill to clinic is scientific and reasonable.

Extract of Zuojin Pill (characters: see text) induces apoptosis of SGC-7901 cells via mitochondria-dependent pathway / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe the effects of water extract of Zuojin Pill ([characters: see text], ZJP) on inhibiting the growth of human gastric cancer cell line SGC-7901 and its potential mechanism.</p><p><b>METHODS</b>Effects of ZJP on SGC-7901 cells growth were determined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay, cell apoptosis and cell cycle were determined by flow cytometry, and apoptosis induction was detected by means of DNA gel electrophoresis. The cellular mechanism of drug-induced cell death was unraveled by assaying oxidative injury level of SGC-7901 cell, mitochondrial membrane potentials, expression of apoptosis-related genes, such as B cell lymphoma/lewkmia-2 (Bcl-2), Bcl-2 associated X protein (Bax) and cleaved caspase-3 and caspase-9.</p><p><b>RESULTS</b>ZJP exerted evident inhibitory effect on SGC-7901 cells by activating production of reactive oxygen species and elevating Bax/Bcl-2 ratio in SGC-7901 cells, leading to attenuation of mitochondrial membrane potential and DNA fragmentation.</p><p><b>CONCLUSIONS</b>ZJP inhibits the cancer cell growth via activating mitochondria-dependent apoptosis pathway. ZJP can potentially serve as an antitumor agent.</p>

Effect of Combination of Rhizoma Coptidis and Fructus Evodiae in Various Proportions on Rat Models with Heat Syndrome Induced by Radix Codonopsis Pilosulae and Radix Astragali seu Hedysari / 广州中医药大学学报

[Objective] To observe the effect of combination of Rhizoma Coptidis (RC) and Fructus Evodiae (FE) in various proportions on rat models with heat syndrome. [Methods] Rat models with heat syndrome were set up by gastric infusion of Radix Codonopsis Pilosulae and Radix Astragali seu Hedysari. Fifty rats were allocated to five groups: normal control group (Group A), model group (Group B), model rats treated with RC and FE at the proportion of 6∶1 (Group C), model rats treated with RC and FE at the proportion of 2∶1 (Group D) and model rats treated with RC and FE at the proportion of 1∶1 (Group E). [Results] Ultrastructure of hepatic cells were improved in Group C, Group D and Group E. Indexes of heat syndrome such as temperature, serum corticosteroid (Cor) level and 17 - hydroxycorticosteroid (17-OHCS) content in homogenate of adrenal glands were decreased in Group C and Group D but stayed unchanged in Group E as compared with Group B ( P

Effects of Liandai Tablet and Its Main Active Components on Gastric Cancer Cell Strain MGC-803 / 广州中医药大学学报

Objective To compare the pharmacological actions of Liandai Tablet(LT) and its main active components on apoptosis of gastric cancer cells and DNA damage. Methods Effects of Liandai Tablet(LT) and its main active components,berberine and indirubin,on growth and apoptosis of gastric cancer cell strain MGC_803 were explored and their effects on DNA damage were also studied. Results LT serum in high and low dosages and berberine could inhibit the growth of MGC_803 as compared with the control group,and typical morphological features of apoptosis were found in the MGC_803 by methyl green pyronin stain assay.But indirubin at various concentrations showed no obvious inhibitory effects. Agarose gel electrophoresis assay revealed that the MGC_803 cell DNA was split into large fragments when treated with berberine. Conclusion LT serum exerts a similar inhibitory effect on the growth and apoptosis of gastric cancer cells as compared with berberine.The effects of LT at various serum concentrations on MGC_803 DNA was less than that of berberine,and indirubin at the given concentration had no this effect.

Comparison of Protective Mechanism of Zuojin Pill and Fan Zuojin Pill on Gastric Mucosa / 广州中医药大学学报

[ Objective] To compare the protective mechanism of Zuojin Pill (Rhizoma Coptidis: Fructus Evodiae = 6:1) and Fan Zuojin Pill (Rhizoma Coptidis: Fructus Evodiae = 1: 6) on gastric secretion and gastric mucosal barrier. [Methods] Pylorus - ligated rat model was applied. Rats were divided into normal saline group, Zuojin Pill groups (1.4 g/kg and 2.8 g/kg) and Fan Zuojin Pill groups (1.4g/kg and 2.8g/kg) and then the drugs were given by duodenal feeding. Gastric secretion and gastric mucus synthesis were examined. [Results] Zuojin Pill and Fan Zuojin Pill (1.4 g/kg and 2.8 g/kg) both inhibited gastric secretion and decreased total acid output and pepsin activity in a dose- effect manner. Zuojin Pill and Fan Zuojin Pill also increased the content of gastric adherent mucus (GAM) and tended to elevate the mucus level in gastric juice. [Conclusion] The preventive mechanism of Zuojin Pill and Fan Zuojin Pill on gastric mucosa may be related to the regulation of gastric secretion and gastric mucus synthesis.
