Résumé

OBJECTIVE:To establish a method for the content determination of glabridin in Clycyrrhizae Radix et Rhizoma from different regions. METHODS:HPLC was performed on the column of Inertsil ODS-SP with mobile phase of acetoni-trile-0.05%phosphoric acid(gradient elution)at a flow rate of 0.8 ml/min,detection wavelength was 280 nm,the column tempera-ture was 35 ℃,and the injection volume was 20 μl. RESULTS:The linear range of glabridin was 0.906-18.12 μg/ml(r=0.999 7), RSDs of precision,stability and reproducibility tests were lower than 3%;recovery was 98.73%-101.90%(RSD=1.25%,n=6). There were obvious differences among the glabridin contents in G. uralensis from different regions. CONCLUSIONS:The method is simple and accurate with high precision,and can be used for the content determination of glabridin in Clycyrrhizae Radix et Rhi-zoma.

Résumé

To explore the clinical application value of 3-dimensional and multiplane reconstruction with MSCT in diagnosing costal cartilage trauma. Totally 19 cases with costal cartilage trauma underwent MSCT 5 mm scanning and 0.625 mm reconstruction, and then went through three-dimensional and multiplane reconstruction. The ac-quired data were transmitted to the computer workstation through the network, and then three-reconstruction was per-formed with the software on AW4.3 platform. There were all 32 costal cartilage fractures in the 19 patients in-volving 15 cases with rib fracture, which included 2 cases and 3 fractures at the chondrosternal junction, 13 cases and 25 fractures in the middle of the costal cartilage, 4 cases and 4 fractures at the junction between costal cartilage and rib. Three-dimensional reconstruction with spiral CT could display clearly the location and number of costal cartilage frac-tures. Three-dimensional and multiplane reconstruction shows clearly the fracture and displacement of the costal cartilage, and the combination of MRP, MIR and VR may contribute to the diagnosis and clinical planning of the costal cartilage fracture.

Résumé

OBJECTIVE: To observe the influence of arecoline (Ar) on human sperm motility in vitro. METHODS: 50 cases of normal human male sperm which had been screened were incubated in different concentration of Ar solution (10 ?g?mL-1,50 ?g?mL-1,100 ?g?mL-1),taking the optimized sperm as control group. After the incubation lasting 0.5,1,2 h, computer assisting sperm analysis system (CASA) was used to analyze the Mot, (a+b) PM,VCL and VSL of sperm. RESULTS: The Mot of sperm incubated in 10 ?g?mL-1 Ar solution for 1 h was significantly different from that of control group(P
