AIM： To address the association between serum total IgE levels and age-related cataract in adults. METHODS： The study participants consisted of 1052 adults aged 40y or older in the Korean National Health and Nutrition Examination Survey 2010. We performed multivariable logistic regression analyses using the quartile cut-points of total IgE levels. RESULTS： The odds ratios （ORs） for nuclear and any cataract with ≥267 kU/L of serum IgE levels were 1.75 [95% confidence intervals （CI）, 1.04-2.96] and 2.00 （95%CI, 1.22-3.27）, respectively, comparing to 35-87 kU/L. Interestingly, participants with ≤35 kU/L of IgE levels （OR, 1.67; 95%CI, 1.02-2.72） also had higher risk for any cataract than those with 35-87 kU/L. The risk for any cataract （OR, 1.48; 95%CI, 1.03-2.13） was higher in participants with high total IgE levels （〉150 kU/L）, comparing to normal participants. CONCLUSION： Our findings indicate a J-shaped relationship between serum IgE levels and age-related cataract.

Paeonol attenuates inflammation-mediated neurotoxicity and microglial activation

引用

Neural Regeneration Research 2013年第18期8卷 1637-1643页

作者： kyong Nyon nam Byung-Cheol Woo Sang-Kwan Moon Seong-Uk Park Joo-young Park Jae-Woong Hwang Hyung-Sup Bae Chang-nam Ko Eunjoo Hwang Lee Graduate School of East-West Medical Science Kyung Hee University Department of Cardiovascular & Neurologic Diseases (Stroke Center) Hospital of Oriental Medicine Kyung Hee University

Chronic activation of microglial cells endangers neuronal survival through the release of various proinflammatory and neurotoxic factors. The root of Paeonia lactiflora Pall has been considered useful for the treatment of various disorders in traditional oriental medicine. Paeonol, found in the root of Paeonia lactiflora Pall, has a wide range of pharmacological functions, including anti-oxidative, anti-inflammatory and neuroprotective activities. The objective of this study was to examine the efficacy of paeonol in the repression of inflammation-induced neurotoxicity and microglial cell activation. Organotypic hippocampal slice cultures and primary microglial cells from rat brain were stimulated with bacterial lipopolysaccharide. Paeonol pretreatment was performed for 30 minutes prior to lipopolysaccharide addition. Cell viability and nitrite （the production of nitric oxide）, tumor necrosis factor-alpha and interleukin-lbeta products were measured after lipopolysaccharide treatment. In organotypic hippocampal slice cultures, paeonol blocked lipopolysaccharide-related hippocampal cell death and inhibited the release of nitrite and interleukin-lbeta. Paeonol was effective in inhibiting nitric oxide release from primary microglial cells. It also reduced the lipopolysaccharide-stimulated release of tumor necrosis factor-alpha and intefleukin-1β from microglial cells. Paeonol possesses neuroprotective activity in a model of inflammation-induced neurotoxicity and reduces the release of neurotoxic and proinflammatory factors in activated microglial cells.

Berberine inhibits inflammatory activation of rat brain microglia

引用

Neural Regeneration Research 2010年第18期5卷 1384-1390页

作者： kyong Nyon nam Jae-Hong Kim Hoon-Ji Jung Jung-Mi Park Sang-Kwan Moon Young-Suk Kim Sun Yeou Kim Eunjoo H. Lee Department of Medical Science Graduate School of East-West Medical ScienceKyung Hee University Department of Cardiovascular & Neurologic Diseases (Stroke Center) Hospital of Oriental MedicineKyung Hee University

Chronic activation of microglial cells endangers neuronal survival through the release of various proinflammatory and neurotoxic factors. Berberine, the effective ingredient of Coptidis Rhizoma and Cortex Phellodendti, has a wide range of pharmacological functions, including anti-inflammatory, anti-atherosclerotic and anti-cancer effects. The neuroprotective potential of berberine has previously been demonstrated. The present study aimed to examine whether berberine could repress microglial activation and can be considered a potential therapeutic candidate to target neurodegenerative diseases. Primary microglial cells and BV2 microglial cells were cultured and stimulated with bacterial lipopolysaccharide （LPS）. Berberine chloride was treated prior to LPS or simultaneously with LPS stimulation. Results revealed that berberine was effective at inhibiting nitric oxide release from primary microglial cells when cells were exposed to the compound prior to LPS or simultaneously with LPS. It also reduced the LPS-stimulated production of tumor necrosis factor-α, interleukin-1β, prostaglandin E2, and intracellular reactive oxygen species and nuclear factor-kappa activation. Additionally, berberine reduced nitric oxide release from microglia stimulated with interferon-γ and amyloid β. These results suggest that berberine provides neuroprotection by reducing the production of various neurotoxic molecules from activated microglia.
