Ginsenoside Rg1 alleviates A deposition by inhibiting NADPH oxidase 2 activation in APP/PS1 mice
Han Zhang,Yong Su,Zhenghao Sun,Ming Chen,Yuli Han,Yan Li,Xianan Dong,Shixin Ding,Zhirui Fang,Weiping Li,Weizu Li 고려인삼학회 2021 Journal of Ginseng Research Vol.45 No.6
Background: Ginsenoside Rg1 (Rg1), an active ingredient in ginseng, may be a potential agent for thetreatment of Alzheimer’s disease (AD). However, the protective effect of Rg1 on neurodegeneration in ADand its mechanism of action are still incompletely understood. Methods: Wild type (WT) and APP/PS1 AD mice, from 6 to 9 months old, were used in the experiment. The open field test (OFT) and Morris water maze (MWM) were used to detect behavioral changes. Neuronal damage was assessed by hematoxylin and eosin (H&E) and Nissl staining. Immunofluorescence,western blotting, and quantitative real-time polymerase chain reaction (q-PCR) were used toexamine postsynaptic density 95 (PSD95) expression, amyloid beta (Ab) deposition, Tau and phosphorylatedTau (p-Tau) expression, reactive oxygen species (ROS) production, and NAPDH oxidase 2(NOX2) expression. Results: Rg1 treatment for 12 weeks significantly ameliorated cognitive impairments and neuronaldamage and decreased the p-Tau level, amyloid precursor protein (APP) expression, and Ab generation inAPP/PS1 mice. Meanwhile, Rg1 treatment significantly decreased the ROS level and NOX2 expression inthe hippocampus and cortex of APP/PS1 mice. Conclusions: Rg1 alleviates cognitive impairments, neuronal damage, and reduce Ab deposition byinhibiting NOX2 activation in APP/PS1 mice.

The Clinical Feature of Behçet’s Disease in Northeastern China
Yingbin Shang,Shixin Han,Jiuhong Li,Qiushi Ren,Fangji Song,Hongduo Chen 연세대학교의과대학 2009 Yonsei medical journal Vol.50 No.5
Purpose: Behçet’s disease (BD) is a chronic, relapsing, multi-system vasculitis of unknown aetiology with complicated and diversified clinical features predominantly involving oral and genital ulcers, and ocular and cutaneous lesions. The clinical features of this disease have been described to be different according to geographical areas and gender. We investigated the specific clinical features of BD patients in Northeastern China. Materials and Methods: 116 patients involved in this study fulfilled the classification criteria of the International Study Group for BD. The clinical manifestations and results of laboratory tests of BD were recorded in each patient. Results: The onset was typically between 20-39 years with a slight female predominance. Oral ulcers were the most common manifestation, followed by skin lesions, positive pathergy reaction/genital ulcers, and ocular lesions. Vascular lesion and epididymitis were rare in patients with BD. The frequency of erythema nodosum-like lesion and articular involvement were significantly higher in females, while gastrointestinal involvement was significantly higher in males. The results of laboratory tests showed that the human leukocyte antigen (HLA)-B*51 alleles were positive in 30.9% of patients and the immunological abnormities were present in some patients. Conclusion: The clinical features of BD showed geographical and gender difference. Genetic and immune factors might participate in aetiopathogenesis of BD.
