ABSTRACT
Objective To investigate the effect of hydroxyl safflor yellow A on mediating blood lipid and to explore its primary mechanism.Methods Fifty KM mice were divided into five groups randomly:control group(A),hyperlipidemia model group(B),high-dose group(C),mid-dose group (D) and low-dose group(E).C,D and E group were injected by hydroxy safflor yellow A with 10,40 and 70 mg.kg-1 day-1respectively,while A and B group were both injected by saline with 0.4 ml day-1,the administrations were kept on three days.The levels of serum total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C) and malondialdehyde (MDA) were assayed,simultaneously the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were assayed after 18 hours.Results Compared with the control group,the serum TC (4.09+0.2) mmol/L,TG (0.96±0.15) mmol/L,LDL-C (5.87±0.17) mmol/L,HDL-C (0.83±0.21) mmol/L,MDA (8.26+1.05) nmol/ml,and the activities of SOD (330.18 ± 11.45 ) U/ml,GSH-Px (1023.54±25.34) U/ml of model group injected high doses of hydroxysafflor yellow A were statistically significant.Conclusion Hydroxy safflor yellow A had the function of mediating blood lipid.Anti-oxidation could be the mechanism.
ABSTRACT
Objective To analyze the roentgenographic findings of the osteopetrosis. Methods Nine patients with clinically suspected osteopetrosis underwent the X-ray examinations of the chest,skull,pelvis,vertebral column,femur,tibiofibula,bones of upper limb and bilateral handbone. The roentgenographs of all patients were analyzed together with review of the literature. Results The basic image feature of osteopetrosis is bone density increased notably,cortible bone thickening,cavum ossis narrowing or occluded and mark X-ray signs include sandwich change in back bone,concentric rings change in pelvis,bone within a bone change,bright-dark alternation transverse striation in metaphysis of tubiform bone,baseball club appearance due to modelling deformity of long bones and periosteal new bone formation. Conclusion Osteopetrosis is a rare inherited disorder. Its mark roentgonographic findings are important evidence for performing the definite diagnosis and differential diagnosis.
