Objectives： Chunghyuldan （CHD）, a combinatorial drug that has anti-hyperlipidemic and anti inflammatory activities, has been shown to reduce infarct volume in a focal ischemia-reperfusion rat model. To explore the molecular basis of CHD＇s neuroprotective effect, we examined whether CHD shows a cell-protective activity and has a regulatory effect on Bax and/or B-cell leukemia/lymphoma 2 （Bcl-2） expression in mouse neuroblastoma 2a （N2a） cells subjected to hypoxia-reoxygenation （H/R）. Methods： In order to evaluate the effects of CHD on the cytotoxicity induced from hypoxia or H/R condition, lactate dehydrogenase （LDH） assay was performed. To explore whether the suppression of neural damage when pre-treated with CHD is associated with its anti-apoptotic effect, the CHD effect on the expression of Bcl-2 and Bax was analyzed by Western blotting analysis. Results： Cytotoxicity of N2a cell line was slightly increased in 42 h hypoxia condition and dramatically increased under the H/R condition. CHD treatment markedly decreased the cytotoxicity in both conditions （P〈0.01, P〈0.05）. H/R markedly increased the expression of the pro-apoptotic protein, Bax, but slightly increased the expression of the anti-apoptotic protein, Bcl-2, compared with the normoxia or hypoxia group. CHD significantly decreased Bax expression （P〈0.01） and slightly decreased Bcl-2 expression （P〉0.05）, resulted in a reduction of Bax/Bcl-2 ratio in N2a cells subjected to H/R. Conclusion： CHD has neuroprotective effect in N2a cells subjected to H/R, which might be derived at least in part from its ability to decrease the expression of the pro-apoptotic protein, Bax.

AIM: To study the mechanism of Je-Chun-Jun (JCJ)-inducing the apoptosis of the human cervical carcinoma, HeLa cells. METHODS: The cell viability was assessed using MTT assay. The optical density was measured at 570 nm. The caspase activity was measured using 50 mmol/L of fluorogenic substrate, AC-DEVD-AMC (caspase-3), AC-VEID-AMC (caspase-8) or AC-LEHD-AFC (caspase-9). To confirm the expression of proteins, Western blotting was performed. To detect the characteristic of apoptosis chromatin condensation, HeLa cells were stained with Hoechst 33258 in the presence of JCJ. For the cell cycle analysis, HeLa cells were incubated with Propidium iodide (PI) solution. Fluorescence intensity of cell cycle was measured using flow cytometry system. RESULTS: The loss of viability occurred following the exposure of 10 g/L JCJ. Cells treated with 10 g/L JCJ for 3 d exhibited the apoptotic morphology (brightly blue-fluorescent condensed nuclei by Hoechst 33258-staining) and the reduction of cell volume. Cells incubated

Uhwang Chungsim Won Decreases Blood Oxygen Level-Dependent fMRI Signal Response to A Motor Stimulation Task

引用

Chinese Journal of Integrative Medicine 2015年第7期21卷 493-499页

作者： Woo-Sang jung Jong-Man Ryu Young-Jee Kim Seong-Uk park Geon-Ho Jahng jung-mi park Sang-Kwan Moon Chang-Nam Ko Ki-Ho Cho Department of Cardiovascular&Neurologic Diseases(Stroke Center) College of Oriental MedicineKyung Hee University Department of Radiology College of MedicineKyung Hee University

Objectives： TO evaluate the effect of Uhwang Chungsim Won [UC, Niuhuang Qingxin Pill （牛黄清心丸] on the blood oxygen level-dependent （BOLD） functional magnetic resonance imaging （fMRI） signal response to a motor stimulation task using a hand grasping paradigm. Methods： Ten healthy right-handed male volunteers were recruited. Their BOLD fMRI signal characteristics during hand grasping were determined before and 1 h after consuming UC. Results： With the administration of UC, BOLD responses to the right hand motor task showed a decrease in both hemispheres including the right cerebellar culmen, right and left medial frontal gyrus, right parahippocampal gyrus, right and left sublobar insula, right and left posterior cingulate, left precuneus, and right precentral gyrus. Decreased BOLD responses to the left hand motor task were shown in the right lingual gyrus, right cerebellar culmen, left superior temporal gyrus, right and left middle frontal gyrus, and right precentral gyrus after UC administration. Increased BOLD responses to the left hand motor task were shown in the left and right posterior cingulate, while there was no increased response to the right hand motor task after UC administration. Conclusions： UC administration significantly decreased fMRI BOLD signal responses to hand grasping in most of the brain areas including the primary motor cortex, but it is not clear whether these decreased responses were caused by a decrease in neuronal activities or by an increase in cerebral blood flow due to the cerebral vasodilatory effects of UC. Further studies using positron emission tomography or single photon emission computed tomography are needed to fully elucidate these findings.

Objective： TO determine whether jaw-tapping movement, a classically described as an indication of personal well-being and mental health, stimulates the memory and the cognitive regions of the brain and is associated with improved brain performance. Methods： Twelve healthy right-handed female subjects completed the study. Each patient performed a jaw-tapping task and an n-back task during functional magnetic resonance imaging （fMRI）. The subjects were trained to carry out the jaw-tapping movement at home twice a day for 4 weeks. The fMRI was repeated when they returned. Results： During the first and second jaw-tapping session, both sides of precentral gyrus and the right middle frontal gyrus （BA 6） were activated. And during the second session of the jaw-tapping task, parts of frontal lobe and temporal lobe related to memory function were more activated. In addition, the total percent task accuracy in n-beck task significantly increased after 4 weeks of jaw- tapping movement. After jaw-tapping training for 4 weeks, brain areas related to memory showed significantly increased blood oxygen level dependent signals. Conclusion： Jaw-tapping movement might be a useful exercise for stimulating the memory and cognitive regions of the brain.

Objective： To investigate brain activity patterns during acupuncture in stroke patients, and to compare the result with normal subjects using functional magnetic resonance imaging （fMRI）. Methods： A total of 11 stroke patients with motor weakness and 10 healthy subjects were studied, fMRI was performed during acupuncture on the left side at points Quchi （Llll） and Zusanli （ST36）. Data were analyzed using statistical parametric maps of brain activation induced by acupuncture stimulation. Results： The results showed that stimulation of both LI11 and ST36 produced significantly different brain activation patterns between the two groups. The normal group showed a greater overall activation than the stroke group. In the normal group, parts of the frontal lobe, parietal lobe, sub-lobar, cerebellum and midbrain regions were activated by acupuncture at the left LI11. On the other hand, only the right side of the inferior parietal Iobule region was activated in the stroke patients. When the left ST36 was stimulated in the normal group, both sides of the frontal lobe, parietal lobe, temporal lobe, and sub-lobar, and the left side of occipital lobe, and the right side of cerebellum and midbrain regions were activated. For the same stimulation in the stroke group, only both sides of the inferior parietal Iobule and cerebellum regions were activated （P〈0.05, cluster level）. Deactivation pattern was not noted during any acupuncture stimulation in both groups. Conclusion： Brain signal activations during the same acupuncture were different between the healthy and the stroke patients, and the effects showed a correlation of different acupuncture points.

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.
