ABSTRACT
Objective:To study the pharmacological effects of Leshibao chewable tablets for juvenile rats with anorexia. Methods:The rats were divided into 6 groups with 10 ones in each and fed with special forage for 4 weeks to establish the anorexia model of ju-venile rats. After the model establishment, from the 8th day, the treatment groups received Leshibao chewable tablets respectively at the dose of 0. 60, 0. 30 and 0. 15 g·kg-1 ·d-1 for three weeks. The general situation was observed, and the appetite and body weight were recorded during the treatment. At the end of experiment, the gastric juice amount, free gastric acidity, total gastric acidity and pepsin activity were determined, TP, ALB, TCHO, MTL and GAS were determined by kit methods. Additionally, the mice were given Leshibao chewable tablets at different doses (0. 80, 0. 40, 0. 20 g·kg-1 ·d-1 ) for 7 days, the effects of Leshibao chewable tablets on gastric emptying and intestinal propulsive function were observed. Results: Leshibao chewable tablets could significantly increase the body weight, appetite (P<0. 05 or P<0. 01), gastric juice amount, free gastric acidity , total gastric acidity and pepsin secretion (P<0. 05 or P<0. 01), significantly reduce TP, ALB and TCHO in serum (P<0. 05 or P<0. 01), significantly increase MTL and GAS contents (P<0. 05 or P<0. 01), and significantly promote gastric emptying and intestinal propulsion in mice (P<0. 05 or P<0. 01). Conclusion:Leshibao chewable tablets can significantly increase body weight and appetite, and improve digestive function re-markably, which exhibit excellent therapeutic effect in the anorexia model of juvenile rats.
ABSTRACT
Objective:To explore the effect and mechanism of SanQi HuoXue pills in the treatment of acute soft tissue injury. Methods:Totally 140 wistar rats were randomly divided into the control group, model group, posistive drug group, and Sanqi Huoxue pills group respectively at the dose of 0. 5,1. 0,2. 0 g·kg-1 . The rat model of acute soft tissue injury was used to observe the influence of Sanqi Huoxue pills on the content of PGE2 , IL-6, NO and SOD on the 3rd and 5th day after the administration, and the effects of the pills on the whole blood viscosity and plasma viscosity were studied as well on the 5th day. Results: After the administration of the pills, the levels of PGE2 , IL-6 and NO, the blood viscosity and plasma viscosity were decreased significantly, and the level of SOD was increased significantly(P<0. 01 or P<0. 05) when compared to model group. Conclusion:Sanqi Huoxue pills have therapeutic effect on acute soft tissue injury in rats. Free radical, PGE2 , IL-6 and blood hemorheology play important roles in the formation of acute soft tissue injury.
ABSTRACT
Objective To approach on the expression pattern of MMP-2 and E-Cadherin in the effects of gastrin on gastric canc-er cells ,so as to investigate their role in the metastasis and invasion of gastric cancer .Methods Genomic DNA modified by sodium bisulfite was used as a template .RQ-MSP detect the methylation status of the gene promoter .The relative amount of Methylation status was performed with comparative threshold cycle (2- △ t ) method .Results MMP-2 and E-Cadherin genes in gastric cancer cells were at hemimethylated status in gastrin before and after the intervention .Gastrin can reduce the methylation levels of MMP-2 gene(P0 .05) .Gastrin can pro-mote the methylation levels of MMP-2 gene ,but proglumide decrease that effect (P<0 .05) .Conclusion Gastrin plays a certain role in the biological behavior of gastric cancer impact by changeing on the expression pattern of MMP-2 and E-Cadherin in the effects of gastrin on gastric cancer cells .
ABSTRACT
Metabolic characteristics of 39 human brain tumor tissues, including 15 astrocytomas, 13 fibroblastic meningiomas and 11 transitional meningiomas from 39 individual patients, have been studied using high resolution magic-angle spinning (HRMAS) 1H NMR spectroscopy in conjunction with principal component analysis (PCA). With rich metabolite information, 1H NMR spectra showed that the tumor-tissuc metabonome was dominated by lipids, lactate, myo-inositol, ereatine, choline metabolites such as choline, phosphocholine and glycerophosphocholine, amino acids such as alanine, glutamate, glutamine, taurine, N-acetyl-aspartate and glutathione. PCA of the tumor NMR spectra clearly showed metabonomic differences between low-grade astrocytomas and meningiomas whereas such differences were more moderate between fibroblastic and transitional meningiomas. Compared with meningiomas, the low-grade astrocytomas had higher levels of glycerophosphocholine, phosphocholine, myo-inositol and creatine but lower levels of alanine, glutamate, glutamine, glutathione and taurine. The N-acetyl-aspartate level was low but detectable in low-grade astrocytomas whereas it was not detectable in meningiomas. It is concluded that tissue metabonomics technology consisting of HRMAS 1H NMR spectroscopy and multivariate data analysis (MVDA) offers a useful tool (1) for distinguishing different types of brain tumors, (2) for providing the metabolic information for human brain tumors, which are potentially useful for understanding biochemistry of tumor progression.
ABSTRACT
@#ObjectiveTo study effect of Herba Erigerontis on metabolites in cerebral ischemia rats with high-resolution magic angle spinning 1H nuclear magnetic resonance spectroscopy(HR MAS 1H NMR). Methods18 male Wistar rats, weighing 150～200 g, were randomly divided into 3 groups such as normal (n=6), ischemia (n=6), Herba Erigerontis treatment (n=6). Rat ischemia model was established with middle cerebral artery occlusion (MCAO), reperfusing or dosed with Herba Erigerontis after 3 h ischemia. The metabolites, including N-acetylaspartate (NAA), creatine (Cre), choline (Cho), glutamate (Glu), and aspartate (Asp) etc., of cerebra and cerebella was observed using HR MAS 1H NMR. ResultsExcluding Cho, Glu, Asp, the concentrations of most metabolites of rat brain during ischemia were significantly lower than that of normal rats, and could be increased after drug treatment. ConclusionHerba Erigerontis shows positive effect on metabolites in cerebral ischemia rats.
ABSTRACT
Background and purpose:Because of the heterogeneity of cancers,different patients with the same kind of cancer have different sensitivity for cytotoxic drugs.Newly developed ATP chemosensitivity assays(ATPTCA) offer the opportunity for individualized therapy and have shown promising results compared to standard regimens.We explored the feasibility of the ATP-Tumor Chemosensitivity Assay(ATP-TCA) applied in the treatment of ovarian cancer with chemotherapy,and evaluate the in vitro sensitivity of fresh specimens of ovarian cancer to five cytotoxic drugs.Methods:ATP-TCA was used to detect the sensitivity rate of 24 fresh specimens of ovarian cancer to five cytotoxic drugs as follows: paclitaxel(TAX),gemcitabine(GEM),doxorubicin(ADM),topotecan(TPT),cisplatin(DDP).Results:23 of 24 specimens((95.83%)) can be evaluated by ATP-TCA,the sensitive rates of ATP-TCA was 91.30% for TAX,86.96% for GEM,65.22% for ADM,47.83% for TPT and 21.74% for DDP,respectively.Conclusions:ATP-TCA was a sensitive、reliable and standardized method for the evaluation of tumor chemosensitivity,it ts worthwhile to investigate further for the application screening anticancer agents in chemotherapy of ovarian cancer.
