The present study is to investigate the protective actions of guggulsterone against the cytotoxicity produced by exposure to hydrogen peroxide (H2O2) in PC12 cells. It was evaluated by MTT [3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyl-tetrazolium bromide] reduction assay, lactate dehydrogenase (LDH) release assay, and the release of nitric oxide (NO). ROS and Ca2+ in cells were evaluated by DCFH and Fura 2-AM, respectively. Mitochondrial membrane potential (MMP) was assessed by the retention of rhodamine 123 (Rh 123). Apoptosis and morphological alteration in PC12 cells were monitored with flow cytometry and electric microscope. Vitamin E, a potent antioxidant, was employed as a comparative agent. The results showed that preincubation of PC12 cells with guggulsterone (0.1-10 μmol·L-1) prevented cytotoxicity induced by H2O2. Extracellular accumulation of LDH, NO and intracellular accumulation of ROS, Ca2+ resulting from H2O2 were significantly reduced by guggulsterone. Incubation of cells with H2O2 caused a marked decrease in MMP, which was significantly inhibited by guggulsterone. The percentage of H2O2-induced apoptosis in PC12 cells was 24.3%, and decreased in the presence of guggulsterone (0.1-10 μmol·L-1) by .8.4%, 15 .9%, 11.8%, respectively. Guggulsterone exhibited comparable potency against oxidative stress induced by H2O2 in PC12 cells as that of vitamin E. The present findings showed that guggulsterone attenuated H2O2-induced cytotoxicity, extracellular accumulation of LDH and NO, intracellular accumulation of ROS and Ca2+, loss of MMP, and apoptosis, which may represent the cellular mechanisms for its neuroprotective action.

Renal interstitial fibrosis is the common pathway for a variety of chronic renal disease to final stage renal failure,the main feature of it is the large accumulation of extra cellular matrix (ECM).Myofibroblasts is the major effector cells which lead to the synthesis of ECM,an important source of myofibroblasts is epithelial-mesenchymal transition(EMT).Wnt/β-catenin signaling pathway take part in the regulation of EMT,which make it become a potential site of anti-fibrosis therapy.

Objective To investigate the characteristics and analyze the differences of choroidal neovascularization (CNV) image between exudative age-related macular degeneration (AMD) and central exudative chorioretinopathy (CEC) using optical coherence tomography (OCT). Methods Twenty-three eyes of 22 patients with exudative AMD and 20 eyes of 19 patients with CEC, which were diagnosed as CNV using fundus fluorescein angiograph (FFA) or indocyanine green angiograph (ICGA), were exami- ned by OCT. The size of CNV and the thickness of retinal neurosensory layer in foveola were measured by OCT software. Results On OCT image, CNV had three main types of morphological features including simple CNV, CNV with serous retinal neurosensory layer detachment and CNV with choroidoretinal exudation. Exudative AMD mainly showed CNV with choroidoretinal exudation (56.52%) and CEC showed simple CNV (90 0%). The thickness of retinal neurosensory layer in foveola of patients with exudative AMD was thicker than that of patients with CEC and the size of CNV of patients with exudative AMD was larger than that of patients with CEC. Negative correlation was found between retinal neurosensory layer thickness in foveola and vision in both groups (?=-0.521, P =0.001). Conclusions There were certain discrepancy in morphology and area involved of CNV between exudative AMD and CEC on OCT images.
