Background: The study was conducted to elucidate the extraction conditions under which white ginseng has cognition-improving efficacy.Methods and Results: Extracts from white ginseng under different solvent and temperature conditions were analyzed for ginsenoside content and inhibitory effect on N-methyl-D-aspartate (NMDA) receptor and acetylcholinesterase. The total ginsenoside contents and amounts of ginsenoside Rb1 plus ginsenoside Rg1 from the 1st extracts (prepared with EtOH/H2O as solvent) were higher than those from the 2nd extracts (extracted with H2O after the 1st EtOH/H2O extraction). The contents in the 1st and 2nd extracts produced at 80°C were also higher than those obtained at 50°C. Samples from the 1st extraction at 80°C indicated higher inhibitory activities on NMDA receptors-whose excessive activation is thought to mediate the calcium-dependent neurotoxicity associated with several neurodegenerative diseases-than those from the 2nd extraction. Among the samples prepared at varying temperatures, the extract prepared at 50°C showed the highest suppression activity on NMDA receptors. Note, however, that the extracts from the 2nd extraction at 50°C inhibited acetylcholinesterase-whose inhibition could be a therapeutic strategy for neurodegenerative diseases with cognitive deficits and memory malfunction-more effectively than those from the 1st extraction.Conclusions: To enhance the cognition-improving activity of white ginseng extract, it is suggested that the extracts be utilized after being combined the 1st extracts (made with EtOH/H2O solvent) and the 2nd extracts (prepared with H2O) at low temperature.

Background: Prenatal exposure to infectious and/or inflammatory insults can increase the risk of developing neuropsychiatric disorder such as bipolar disorder, autism, and schizophrenia later in life. We investigated whether Valeriana fauriei (VF) treatment alleviates prepulse inhibition (PPI) deficits and social interaction impairment induced by maternal immune activation (MIA).Methods and Results: Pregnant mice were exposed to polyriboinosinic-polyribocytidilic acid (5㎎/㎏, viral infection mimic) on gestational day 9. The adolescent offspring received daily oral treatment with VF (100㎎/㎏) and injections of clozapine (5㎎/㎏) for 30 days starting on the postnatal day 35. The effects of VF extract treatment on behavioral activity impairment and protein expression were investigated using the PPI analysis, forced swim test (FST), open field test (OFT), social interaction test (SIT), and immunohistochemistry. The MIA-induced offspring showed deficits in the PPI, FST, OFT, and SIT compared to their non MIAinduced counterparts. Treatment with the VF extract significantly recovered the sensorimotor gating deficits and partially recovered the aggressive behavior observed in the SIT. The VF extract also reversed the downregulation of protein expression induced by MIA in the medial prefrontal cortex.Conclusions: Our results provide initial evidence of the fact that the VF extract could reverse MIA-induced behavioral impairment and prevent neurodevelopmental disorders such as schizophrenia.

Background : Cellular damage caused by excessive reactive oxygen species (ROS) and peroxynitrite (ONOO-) generations has been implicated in several human diseases. The present study was carried out to evaluate the in vitro ROS and ONOO- scavenging activities of Cirsium japonicum parts. Methods and Results : The dried Cirsium japonicum parts (whole plant, leaf, seed coat) were extracted by EtOH, at room temperature. In order to determine antioxidant activity of Cirsium japonicum parts, we were carried out ROS and ONOO- scavenging analyses. As a result , the IC50 in ROS scavenge were showed 203.99 ± 22.04 μg/ml, 174.44 ± 7.78 μg/ml, 86.77 ± 7.02 μg/ml. The IC50 in ONOO- scavenge were showed 15.68 ± 0.57 μg/ml, 12.99 ± 0.15 μ g/ml, 10.33 ± 0.19 μg/ml, respectively. Active compound content in C. japonicum was determined using a HPLC/UV, reverse-phase column with gradient elution program (water in 0.5% formic acid : acetonitrile = 100:0 to 0:100 for 45 min, 0.8 ml/min). UV detection was conducted at 340 nm. The content of apigenin was measured in whole plant (1.04±0.06 mg/g), leaf (0.91±0.02 mg/g), seed coat (33.33±0.93 mg/g). Conclusion : Each part of Cirsium japonicum was analyzed antioxidant activity and the content of apigenin with EtOH extract. In result antioxidant activity, seed coat > leaf > whole plant. Seed coat were showed a very strong antioxidant activity. The comparative patterns between the antioxidant capacity and HPLC analysis results for the apigenin contained in Cirsium japonicum may also prove to be significant.

Background : Ganoderma lucidum is a non-toxic, medicinal mushroom, which is known to possess anti-inflammatory and immunomodulating activities. However, the effects and mechanism of action of Ganoderma lucidum on lipopolysaccharide (LPS) and interferon-gamma (IFN-γ)-induced nitric oxide (NO) production and its-related cytokine expression are not yet fully understood. This study aimed to evaluate the effect of Ganoderma lucidum on NO production and NO-mediated pro-inflammatory cytokine expression in LPS/IFN-γ-induced RAW 264.7 macrophage-like cells. Methods and Results : The results showed that Ganoderma lucidum inhibited inducible NO synthase (iNOS) expression of RAW 264.7 macrophage-like cells at non-cytotoxic concentrations probably through the reduction of reactive oxygen species (ROS) production. After pre-treatment of cells with non-toxic doses of Ganoderma lucidum; NO production was significantly decreased. Moreover, Ganoderma lucidum treatment suppressed LPS/IFN-γ -stimulated pro-inflammatory cytokine secretion, including interleukin-1β and interleukin-6, in a dose-dependent manner. Conclusion : Taken together, these results indicate that the anti-inflammatory activation of Ganoderma lucidum in LPS/IFN-γ-stimulated macrophages might be due to abrogation of NO-dependent cytokine release by impairment of iNOS expression via ROS generation.

Background : In this study, we investigated the renoprotective effects of serotonin and its derivatives, on the renal function and expression of inflammation and apoptosis in cisplatin-induced nephrotoxicity mice. Methods and Results : Serotonin and its derivatives were orally administered at a dose of 7.5 mg/kg body weight for 5 days before the intraperitoneal injection of cisplatin 20 mg/kg body weight, and the effects were compared with those of vehicle-treated nephrotoxicity control and normal groups. In the serum and kidney, renal function parameters, reactive oxygen species and expression of protein related to pro-oxidant, antioxidant, inflammation and apoptosis were examined. As a result, serotonin and its derivatives administrations to nephrotoxicity mice lowered serum BUN and creatinine concentrations. These results were derived, at least in part, from attenuation the expression of antioxidant enzymes-related proteins, SOD and GPx. In the cisplatin-induced renal condition, augmented p-p38, p-ERK and p-JNK (mitogen-activated protein kinase pathway) were reduced with a increase in antioxidant enzymes on serotonin and its derivatives treatment. Moreover, in the serotonin and its derivatives-treated groups, NF- κB-induced inflammatory factors and apoptotic protein expressions were regulated in the kidney. Conclusion : The present study indicates that serotonin and its derivatives exerts a renoprotective effect against cisplatin-induced nephrotoxicity through the recovery of kidney function deterioration and attenuation of renal inflammation and apoptosis by regulating oxidative stress condition.

Background : Management of air temperature are known to primarily affecting on physiological properties and yield in plant. Methods and Results : The effect of air temperature on characteristics of photosynthesis and chlorophyll fluorescence in Schisandra chinensis Baillon were investigated under controlled temperature using growth chamber. Net photosyntheis rate, transpiration was measured at 1,000 μmol m-2 s-1 of photon flux density and chlorophyll fluorescence was analyzed by OJIP method. Net photosyntheis rate and transpiration rate was higher in treatment of 25℃. As results of chlorophyll fluorescence by OJIP analysis, maximum quantum yield (Fv/Fm) of photosystem II (PSII) and PIabs was higher in treatment of 25℃ which reflects the relative reduction state of PSII. But in treatment of 35℃ the relative activities per reaction center such as ABS/RC, DIo/RC were higher than in treatment of 25℃ which implied that the relative reduction of electron transport at PSI and increasement of photo inhibition at reaction center. Conclusion : This result implies that 25℃ of air temperature may be a adequate temperature to improving the efficiency of photosynthesis through controlling a photosystem in Schisandra chinensis Baillon.

Background : Oxidative stress-related iflammatory mechanisms may play an important role in the pathogenesis of cisplatin-induced nephrotoxicity. Safflower (Carthamus tinctorius L.) seed is a crude drug rich in serotonin derivatives to exhibit several biological activities, including antioxidant, anti-inflammation and anti-cancer effects. The purpose of this study was to determine the renoprotective effects of Safflower seed, using cisplatin-induced nephrotoxicity mice. Methods and Results : Safflower seed was orally administered at a dose of 100 and 200 mg/kg body weight for 5 days before the intraperitoneal injection of cisplatin 20 mg/kg body weight, and the effects were compared with those of vehicle-treated cisplatin administered to control and normal mice. In the serum and kidney, renal function parameters reactive oxygen species and expression of protein related to oxidative stress, DNA damage, inflammation and apoptosis were examined. Safflower seed treatment attenuated serum BUN, createinine and renal oxidative stress through reduction of reactive oxygen species and increase in the protein expression level of catalase. Safflower seed reduced renal protein expression of p-p38 and p-JNK (mitogen-activated protein kinase pathway), pro-apoptotic factors (such as Bax and caspase 3) and nuclear factor-kappa B-targeting pro-inflammatory cyclooxygenase-2 and inducible nitric oxide synthase. In addition, Safflower seed treatment led to significantly attenuated histological damage in the kidney. Conclusion : These renoprotective effects of Safflower seed were achieved through attenuation of oxidative stress and its sensitive protein expression associated with inflammation and apoptosis in cisplatin-induced nephrotoxicity mice.
