RESUMO
Objective To explore the clinical application value of 64-layer spiral CT three-dimensional imaging in sty-loid process syndrome. Methods Imaging data of three-dimensional imaging of 42 patients with styloid process syn-drome who were examined from 2013 to 2014 were collected and retrospectively analyzed. The thickness and spacing of scanning layer were both 1 mm, and the tread pitch was 1. Reconstruction techniques of MIP and VR were applied for processing. Results Three-dimensional images of 42 patients(MIP image,VR image)all distinctly manifested the over-all picture of styloid process and imaging findings. Conclusion The combined application of MIP and VR reconstruc-tion techniques, as well as the comprehensive analysis of axial imaging are able to significantly improve the accurate diagnosis of styloid process syndrome via spiral CT, which provides significant values for clinical diagnosis of diseases and surgery.
RESUMO
Object To investigate the synthesis of alkaloids by cell suspension cultures of Datura metel L. Methods Cultured cells derived from leaves of D. metel were m aintained in Murashige and Skoog (MS) liquid medium. The effects of different c arbohydrated, different inoculum sizes, and different pH values of medium as aff ecting facters on cell growth and alkaloid formation were studied. Re sults The optimum carbohydrate was sucrose, inoculum size (1.5 - 2. 0 g/L) for fresh weight and initial pH values (5.5-6.0) of the medium were benefit for cell growth and alkaloid synthesis in the suspension cultures. The synthesis of alk aloids was improved when exogenous phenylalanine added to the culture. Conclusion Suspension-cultured cells of D. metel c an be used to synthesize alkaloids.
