Objective To characterize the effects of Sanchi on the alcoholic hepatopathy rats.Methods 70 SD male rats were randomly divided into five groups:normal group(n=10),control group(n=15),high-dose Sanchi group(n=15),low-dose Sanchi group(n=15),and Tiopronin group(n=15).In order to induce alcoholic hepatopathy,animals in the control,high-dose and low dose Sanchi,and Tiopronin groups were orally dosed with HongXing ErGuoTou(56% ethanol;5g/kg),corn oil(2ml/kg),and pyrazole(27.2 mg/kg)every morning for 14 weeks.Rats in high-dose Sanchi,low dose Sanchi,and Tiopronin groups,were treated every afternoon during the 14-week induction of hepatopathy,with 1.2g/kg Sanchi,0.6g/kg,and 100mg/kg Tiopronin,respectively.All rats were sacrificed 12 hours following the last injection.Blood samples were obtained prior to euthanization.Blood-fat and serum lipoidase activity were measured using an automatic blood biochemical analyzer.Blood haluronic acid(HA),laminin(LN)were determined by ELISA.Histopathological changes of hepatic tissues(i.e.steatosiss,inflammation,and fibrosis)were assessed by microscopic examination of HE and Masson staining of the right lobe of livers.Results Compared with rats from the normal group(treated with ddH2O),rats in the control group have significantly higher steatosis,inflammation,liver fibrosis,and increased level of serum cholesterol,HDL-C,LDL-C,haluronic acid,laminin and AST/ALT activity,(P0.05).More importantly,treatment with high-dose,low-dose Sanchi,or Tiopronin resulted in less severe steatosis,inflammation,fibrosis in the liver,and reduced the levels of serum haluronic acid,laminin(P0.05).Conclusions(1)Daily dosing of alcohol,corn oil,and pyrozole for 14 weeks faithfully replicated the alcoholic hepatopathy symptoms observed in the ALD model,such as hepatic steatosis,immune cell infiltration,blood-fat disturbance,increase in serum AST/ALT activity,and liver fibrosis.(2)Sanchi can significantly alleviate the symptoms in the alcoholic hepatopathy rats including steatosis,improve hepatic function and fibrosis.

The data analysis of food supervision needs to reflect the integration of food safety and possible trend based on the fun-damental test data of stressed foods and their products. With the assessment and analysis on potential resources of hazard elements, the integrate management support of food safety could be achieved. The data management could be organized and evaluated through plan, collection, treatment and display, which might be assisted to establish data-link with process mining to enforce the prospect of food safety background and trend and to provide the support of food safety management.

BACKGROUND: Learning and memory is a very complex biological phenomenon. Although quite a few researches on the substances participate in learning and memory and the brain areas related with learning and memory,its mechanism is still not completely clarified.OBJECTIVE:ro study the difference of antioxidase activity at different brain area in rats with different ability of learning and memory to reveal the relationship between the ability of learning and memory and the activity of antioxidase in specific brain area.DESIGN: A randomized controlled trial based on the experimental animals.SETTING: Department of Biochemistry in Jining Medical College.MATERIALS: The study was conducted in the Laboratory of Biochemistry of Jining Medical College and Suzbeu Medical College between March 2001 and January 2004. Forty 15-month old male Wistar rats with a body mass between 580 g and 650 g were selected.INTERVENTIONS: The detection of learning memory ability was carried out in MG-2 trisection radiation maze. Correction response was that the rats escaped to safe area after electric shock. Standard of master was that the rats had 9 out of 10 times continuously of correction. Observatory indicators included times of response required reaching the standard and the correct response rate. Good learning. ability meant 40 or less than 40 times of responses to reach standard; otherwise, poor learning ability was considered. Detection was repeated after 24 hours to observe the memory. Good memory meant 3 times continuously of correct response; otherwise, poor memory was considered. Rats with good learning ability and memory were included into group 1 (n= 10) and the rats with poor learning ability and memory were included into group 2( n = 12). The rest rats were washed out.MAIN OUTCOME MEASURES: Activities of superoxide dismutase (SOD), catalase(CAT) and glutathione-peroxidase(GSH-Px) of five brain areas including cerebral cortex, cerebella, striatum, hippocampus and hypothalamus in rats of two groups.RESULTS: To compare the rats with poor learning and memory ability with rats with good learning and memory ability: SOD activity in cortex, hippocampus and striatum significantly reduced ( t = 3.82, 4. 50, 6. 76, P ＜0.01); CAT activity in cortex, hippocampus, striatum and hypothalamus significantly reduced(t =4.75, 7.06, 10. 88, 17.28, P＜0.001); and GSH-Px activity was similar in each brain area without statistical significance.CONCLUSION: Hippocampus, cortex, striatum and hypothalamus all might participate in learning memory process, and the activities of antioxidases in these areas are closely related with learning memory.

P53 protein plays a crucial role in inhibition tumor development.It will accumulate in cells in the condition of DNA damage,oncogenes activation or stress.As a nuclear transcription factor,P53 can transactivate the genes which correlate with apoptosis,cell cycle control and other procedures. Current research reveals P53 outside the nucleus can induce apoptosis and inhibit autophagy which contributes to its function of tumor suppression.The study of the extranuclear function of P53 is beneficial to further understanding the mechanism of P53 in the genesis and development of tumor.
