Objective To observe the protective effect of Mongolian medicine Carthamus tinctorius in acute liver injury induced by D-GlaN(D-galactosamine)in rat models. Methods The acute liver injury model was established by intragastric administration D-GlaN in rats. The levels of serum aspartate aminotransferase(AST),alanine aminotransferase(ALT),glutathione(GSH-Px),the content of tumor necrosis factor-α(TNF-α)in liver tissue and the apoptosis of hepatocytes were determined. Results Mongolian medicine safflower can significantly reduce the activity of serum ALT and AST and liver tissue GSH-Px,and the degree of cell apoptosis;however,no obvious change of the TNF-αcontent was observed. Conclusion The Mongolian medicine Carthamus tinctorius has protective effect in D-GlaN-induced acute liver injury rats probably via anti-oxi-dative and anti-apoptotic abilities.

Abnormal elevation and abnormal isoenzyme of non-specific esterase (?-NAE) are intimately associated with the genesis and development of cancer.Anti-GCBAP is a new kind of biological response modifier(BRM) which is separated from gastric cancer cells immunized animal spleen. As determined by clonogenic assay. Anti-GCBAP displayed highly-potent, specific cytotoxicity regarding to target cancer cells. In the present study, we have further investigated the effect of Anti-GCBAP on the ?-NAE isoenzymes in gastric cancer-bearing nude mice. The results demonstrated that in vivo adminstration of Anti-GCBAP can not only inhibit tumor growth in tumor-bearing mice, compared with control(p

Objective To explore the value of biomechanics parameter of rabbit abdominal aortic atheroma using velocity vector imaging(VVI).Methods Ten of 45 male New Zealand rabbits were chosen as normal control group randomly,the rest experimental rabbits were made atheromatous plaque model.The rabbits were examined by two-dimensional ultrasound and VVI respectively.The intima-media thickness(IMT) or thickness of plaques of abdominal aorta 1 cm from right renal artery branch were recorded.Maximum tangential velocity,strain and strain rate of IMT or plaques were measured using VVI.Then the rabbits were killed for pathological and immuno-histochemical examination.Results Based on pathology,the rabbites were divided into 4 groups:control group(group A,n=10),group of pathological endometrial thickening(group B,n=9),group of thick fibrous cap atheromatous plaques (group C,n=15) and group of thin fibrous cap atheromatous plaques (group D,n=11).The difference of plaques thickness and biochemical indicators had no statistically significant between group B and C(P>0.05),both bigger than group A and B (P<0.05).The difference of Vmax,Smax and SRmax had statistically significant each group(P<0.05).With Vmax>0.46×10-2 cm/s,Smax>0.37%,SRmax>1.415×10-2 s-1 to find the vulnerable plaques,the sensitivity were 75.0%,84.4%,84.4% respectively,specificity were 70.8%,91.7%,83.3% respectively.Conclusions VVI can identify plaque biomechanics parameter of different progression periods,which is expected to be a reliable method to find vulnerable plaques earlier in clinic.

Objective To explore the value of abdominal aorta strain reserve(SR) of rabbits during the period of early atherosclerosis using velocity vector imaging(VVI) techniques combined with nitroglycerin (NTG) vasodilation experiment.Methods Fifty-two male New Zealand White rabbits were used in this experiment.Group A(n=12) was the normal control group.Forty rabbits were made into atherosclerosis models.The SR of abdominal aortas of all rabbits were analyzed in short axis views using VVI and NTG vasodilation experiment at the forth week and the eighth week after feeding.The period of atherosclerosis into endothelial injury stage(group B) and intima thickening stage(group C) were divided.Results There were eighteen rabbits at the endothelial injury stage in group B and thirteen at the intima thickening stage in group C.Compared with control group,arterial SR values of group B and group C were significantly decreased in turn [4.13±1.21＞2.31±0.89＞1.22±0.77,Z=-2.978,P=0.003;Z=1.959,P=0.001],IMT of group C was significantly higher than that of group A(Z=-3.108,P=0.002),strain of group C was significantly lower than that of group A(Z=-2.415,P=0.016),the strain and IMT had no significant difference among three groups except group A and group C (P>0.05).A cut-off value was 3.67 of SR for diagnosing the endothelial injury aretary had a sensitivity of 70% and spectificity of 92.3% respectively obtained by the area under the ROC curve.The agreement of this diagnosis was very good.Conclusions The variable of the SR could stand for the variable of the vascular elasticity during the period of the early atherosclerosis.VVI and NTG vasodilation experiment could quantitatively assess SR of abdominal aortas of rabbits.
