A high-performance liquid chromatographic method with evaporative light scattering detection (HPLC-ELSD) has been developed to identify and quantify 19 ginsenosides (Rg(1), Re, Rf, Rb(1), Rc, Rb(2), Rd, F(4), Rg(6), Rk(3), Rh(4), 20(S)-, 20(R)-Rg(3), 20(S)-, 20(R)-Rs(3), Rk(1), Rg(5), Rs(4), and Rs(5)) in black ginseng (BG, Korean white ginseng that was(More)
To optimize ginsenosides hydrolyzing beta-glucosidase production from Aspergillus niger, response surface methodology was carried out in two stages. The Plackett-Burman design was achieved to screen the important variables that influence beta-glucosidase production. Among 10 variables (wheat bran, soybean powder, CaCl(2), ginsenosides, KH(2)PO(4), MgSO(4),(More)
PURPOSE The aim of the study is to probe whether intratympanically gadolinium contrast-enhanced three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging, together with magnetic resonance imaging scoring system of the perilymphatic space, had advantages in diagnosing patients with bilateral Meniere's disease. MATERIALS AND METHODS(More)
OBJECTIVE To explore the positive visualization rate of endolymph space in Meniere's disease (MD) by three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D-FLAIR MRI) and assess its diagnostic value of MD. METHODS 3D-FLAIR MRI was performed at 24 h after an intratympanic injection of gadolinium diethylenetriamine penta-acetic(More)
20(S)-protopanaxadiol (PPD(S)) and 20(R)-protopanaxadiol (PPD(R)), the main metabolites of ginsenosides Rg3(S) and Rg3(R) in black ginseng, are potential candidates for anti-cancer therapy due to their pharmacological activities such as anti-tumor properties. In the present study, we report the preparation of PPD(S, R) by a combination of steaming and(More)
OBJECTIVES/HYPOTHESIS To investigate endolymphatic space images in patients with idiopathic sudden sensorineural hearing loss (ISNHL) and vertigo using three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D-FLAIR MRI). STUDY DESIGN This is a prospective study of an analysis using the imaging technology of 3D-FLAIR MRI for(More)
