토마토 온실에서 담배가루이 (Bemisia tabaci) 유인을 위한 작물에 따른 선호도를 조사하였다. 피망, 토마토, 오이, 가지의 4 종류의 작물을 아크릴케이지에 같이 넣어두고 담배가루이 성충 30쌍을 방사하여 선호도 및 산란수를 조사하였다. 담배가루이 성충은 오이(약 40%)와 가지(약 40%)에서 가장 선호하였으며, 토마토(10%)와 피망(10%)의 선호도는 낮았다. 기주에 따른 담배가루이의 성충 30쌍의 산란수는 오이에서 485개로 가장 높았으며 가지(250), 토마토(131), 피망(126)의 순으로 조사되었다. 토마토 온실에 가지묘를 정식하였을 경우에는 토마토에서는 주당 약 20마리의 담배가루이가 조사되었으나 가지에서는 주당 400∼500마리의 담배가루이가 조사되어 토마토 온실에서 가지를 이용한 담배가루이 유인이 가능함을 알 수 있었다.

본 연구에서는 주요 발생지인 구례 지역의 산수유, 때죽나무를 중심으로 2018년 8월에서 9월 사이에 갈색날개매미충 월동 난괴를 채집하여 날개매미충알벌(phanuromyia spp.)의 온도별(15℃, 20℃, 25℃, 30℃) 발육기간, 수명 및 우화 후 15일간의 총 산란수를 조사하였다. 날개매미충알벌의 발육기간은 25℃에서 알 2.6일, 유충 5.4일, 번데기 15.0일, 30℃에서 알 1.9일, 유충 7.6일, 번데기 13.7일이 소요되었다. 날개매미충알벌 성충의 온도별 수명은 15℃에서 암컷 77.4일, 수컷 66.6일, 20℃에서 암컷 49.0일, 수컷 44.0일, 25℃에서 암컷 27.6일 수컷 28.4일, 30℃에서 암컷 18.0일, 수컷 14.0일로 암수 모두 사육온도가 높아질수록 수명이 짧아졌으며 15℃와 30℃에서만 암수 수명의 차이가 있었다. 또한 온도별 총 산란 수는 15℃를 제외한 나머지 세 가지 사육온도에서 산란 수 차이는 없었으나 25℃에서 평균 23.2개로 가장 높았다.

It was available to store both nymphs and adults of Geocoris pallidipennis at 5℃ for 3 weeks without negative effects on their survival, fecundity, and Bamisia tabaci nymph predation. Up to 140 days, it was also possible to store Micromus angulatus adults at low temperature, showing approximately 50% cumulative survival rate, but over 2 week cold storage was not suitable for their fecundity. With the increase of cold storage duration, the aphid predation by M. angulatus decreased, but it could be possible to cold store until 5 weeks without a significant effect on their aphid predation. Thus, short term cold storage of G. pallidipennis and M. angulatus could be useful for inundative biological control.

약제 처리에 따른 담배거세미나방(Spodoptera litura) 유충의 섭식 행동 및 반응을 조사하기 위해 1분 간격으로 잎면적을 자동 측정하였다. 담배거세미나방 유충의 섭식 행동은 섭식기와 비섭식기가 뚜렷하게 구분되었으며, 섭식기가 끝나면 비섭식기를 거쳐 탈피를 하고 다시 섭식기에 들어갔다. 1회 섭식 지속 시간은 약 15분으로 조사되었고, 영기 내 평균 섭식 회수는 약 27.5회로 섭식 지속 시간과 마찬가지로 영기에 따른 차이는 없었다. 약제 처리는 피망 잎을 Buprofezin methoxyfenozyd과 BT (Bacillus thuringiensis) 500ppm 약액에 10초간 침지 처리하였다. Buprofezin methoxyfenozyd를 처리 하였을 경우 섭식 시간은 평균 8~9분으로 감소하였고, 치사 전까지 섭식량은 각각 176mg으로 조사되었다. 하지만 BT제를 처리 시에는 담배거세미나방 유충은 치사하지 않았다.

Ganoderma lucidum has been reported to have various biological activities including antioxidant activity. The objective of this study was to compare the antioxidant effects between Ganoderma lucidum (GL) and antler-shaped fruiting body of Ganoderma lucidum (AGL). In vitro antioxidant activities were examined by 2,2-diphenyl-picrylhydrazyl hydrate (DPPH) and 1,2,2-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities of GL and AGL ethanol extracts. In the DPPH and ABTS radical scavenging activities of GL and AGL ethanol extracts, antioxidant activities of AGL extracts (IC50, 66.94 μg/ml and 131.23 μg/ml) was showed higher than GL extracts (IC50, 83.93 μg/ml and 164.54 μg/ml). Total polyphenol content and total flavonoid content (38.00 g GAE/kg extract and 11.58 g NE/kg extract) of AGL were found higher as compared to GL (34.23 g GAE/kg extract and 3.46 g NE/kg extract). In summary, the results of this study demonstrate that AGL extracts had higher antioxidant activities to GL.

The purpose of this study was to investigate whether or not the antler-shaped fruiting body of Ganoderma lucidum (GL) has an anti-inflammatory effect on lipopolysaccharide (LPS)/interferon-γ (IFN-γ)-activated RAW 264.7 macrophage-like cells. To evaluate the anti-inflammatory effects of GL, we examined the inflammatory mediators such as the production of nitric oxide (NO) and the expression of mitogen-activated protein kinase (MAPK), activator protein 1 (AP-1), inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin-1β (IL-1β), and interleukin-6 (IL-6). LPS/IFN-γ-induced cellular NO production was significantly decreased in GL-treated RAW 264.7 cells. Moreover, Western blotting analysis results demonstrated that reduced protein expression of MAPK families (such as extracellular signal-regulated kinase, c-Jun amino-terminal kinase, and p38 MAPK) and AP-1-targeting inflammatory enzymes (iNOS, COX-2, IL-1β, and IL-6). These results indicated that GL modulates the MAPK/AP-1 signal pathway in inflammatory process. In conclusion, the present study provides important evidence that GL can potentially be used to reduce LPS/IFN-γ-induced inflammatory response by inhibiting the MAPK/AP-1 signaling pathways.

two different sizes of yellow sticky traps (small trap: 9.6×8.0cm; large trap: 9.6×16cm) for sampling greenhouse whitefly (GHWF), Trialeurodes vaporariorum (Westwood), adults in four commercial cherry tomato greenhouses. The patch size of GHWF immatures between plants was also estimated using visual counts. Two variogram models were fitted to the empirical variograms developed from the data collected by each sampling method. All the variograms reached the sill indicating the presence of spatial dependence among the spatial data obtained by the two sampling methods. For GHWF adults on sticky traps the range of variogram (a measure of attractive distance) was not different between the two trap sizes. This result indicated that the attractive distances of the two different yellow sticky traps were very similar. The ranges of the variograms for the visual count of immatures on plants were always less than those for adults, indicating that the attractive distance of the traps for GHWF adults extends beyond the patch size for immatures on cherry tomato plants. These data have implications for developing sampling plans for the management of GHWF in tomato greenhouses.

Background : Scopolamine induces cholinergic dysfunction and oxidative stress, and the impairment of memory function. Therefore, oxidative stress and cholinergic dysfunction are important role of the brain pathology of amnesia. In this study, we investigated the impact of Safflower seed against oxidative stress and cholinergic dysfunction on scopolamine-induced amnesic mice. Methods and Results : Mice were orally pretreated with safflower seed (100 ㎎/㎏ body weight) or vehicle for 7 days, and scopolamine (1 ㎎/㎏ body weight) was injected intraperitoneally, 30 min before the behavior tests such as T-maze and novel objective recognition test on first day. To evaluate learning and memory function, the Morris water maze task was performed for 5 days, consecutively. The results showed that spatial perceptive ability and novel object recognition was significantly increased by preadministration of safflower seed compared with scopolamin-induced control mice in the behavior tests. Consistently, immuno blot revealed the elevated expression of superoxide dismutase 1 in the safflower seed pretreated mice, compared to the control mice. Moreover, protein expression of acetylcholinesterase was decreased in safflower seed pre-treated group. Conclusion : Subsequently, our results suggests that the Safflower seed extract improved memory impairment through inhibition of cholinergic dysfunction and oxidative stress.

Background : Oxidative stress and inflammatory response are important features of the brain pathology of Alzheimer's disease. Therefore, the purpose of this study was to the antioxidant activity and biochemical characterization of safflower seed. Moreover, we investigated the impact of Safflower seed on scopolamine-induced memory impairment in mice. Methods and Results : First, in order to determine active ingredient contents of safflower seed extract, we were carried out total phenol content and total flavonoid content analyses. As a result, dried safflower seed were found to contain 35.4 ± 0.4 ㎎·GAE/g dry weight and 45.3 ± 7.5 ㎎·NE/g dry weight in boiling water extraction. Also, the major compounds of safflower seed from HPLC analysis were identified as serotonin and serotonin derivatives [N- (p-coumaroyl)serotonin and N-feruloylserotonin]. In addition, the antioxidant activity of safflower seed showed IC50 values of 331.4 and 168.2, respectively, against DPPH and ABTS in vitro. Finally, with regard to the memory improvement activity, the administration of Safflower seed extract significantly restored memory impairments induced by scopolamine in the behavior tests such as novel object recognition and Morris water maze test. Conclusion : The results of our study suggest that the safflower seed extract possess potent memory improvement activity and are also a good source of natural antioxidants. Further study is needed to identify the mechanism responsible for their memory improvement activity.

Background: Glycyrrhiza uralensis Radix (GR) is a crude drugs used in Asian countries that has been reported to prevent the progression of neurodegenerative diseases such as Alzheimer’s disease. The present study examined whether GR and its active compounds, glycyrrhizic acid (GA) and isoliquiritigenin (IL), exerted protective effects on H2O2-induced oxidative damage in C6 glial cells. Methods and Results: We exposed C6 glial cells to hydrogen peroxide (H2O2) for 24 h and investigated the cellular response to GR and its active compounds by evaluating cell viability, reactivie oxygen species (ROS) production, and apoptosis-related protein expression. GR successfully mitigated the reduced cell viability and ROS production induced by H2O2 in C6 glial cells, IL and GA significantly increased the cell viability and decreased ROS production. In addition, IL and GA down-regulated apoptotic Baxdependent caspase-3 activation, but each compound exerted different mechanisms, i.e., IL dose-dependently decreased ROS production and, GA up-regulated anti-apoptotic Bcl-2 expression. Conclusions: These results demonstrated that GR and its active components, IL and GA, exhibit potential for use as natural neurodegenerative agents for the modulation of apoptosis in C6 glial cells.

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.

β amyloid protein (Aβ) plays a critical role in the pathogenesis of Alzheimer's disease (AD) and possibly in Aβ -induced mitochondrial dysfunction and oxidative stress. Aβ can directly cause reactive oxygen species (ROS) production. Overproduction of ROS is considered to be involved in the pathogenesis of neurodegeneration of AD. Here, we investigated 9 kinds of ramie (Boehmeria nivea, (L.) Gaud., BN; hereafter denoted as BN) for their protective action against oxidative stress in a cellular system using C6 glial cells. We observed loss of cell viability and high levels of ROS generation after treatment with hydrogen peroxide (H2O2) and Aβ25-35. However, treatments with BN extracts led to an increase in cell viability and decrease in ROS production induced by H2O2 and Aβ25-35. In particular, the extracts of BN-01 (seobang variety from Seocheon) and BN-09 (local variety from Yeonggwang) showed excellent anti-oxidative properties. This indicates that BN extracts could prevent neurodegeneration by reducing oxidative stress in cells.

Content analysis of loliolide in the leaves of Boehmeria nivea (Bn) collected from different region during four months (June, July, August, and September) was conducted by HPLC. The content of loliolide was detected in the leaves of B. nivea from Bns-2, -7, -10, -23, -38, -41, -67, -76, and -90 in June (5.02, 6.35, 6.93, 5.89, 4.31, 4.24, 4.91, 5.12, and 5.46 mg/g, respectively), July (4.32, 6.42, 7.72, 7.97, 4.05, 4.32, 5.65, 6.67, and 5.39 mg/g, respectively), August (3.52, 5.17, 3.90, 4.27, 3.26, 4.72, 3.82, 3.30, and 3.31 mg/g, respectively), and September (7.04, 7.25, 7.43, 7.86, 6.76, 6.38, 7.60, 6.79, and 4.77 mg/g, respectively). Among them, the highest content of loliolide was found in Bn-23 and in September. These results may be useful in determining the optimal harvest time at which phytochemical reaches a maximum level.

To evaluate therapeutic efficacy of aldose reductase (AR) inhibition, the seeds of Perilla frutescens var. japonica (PF) were tested for inhibition of AR. The stepwise polarity fractions of PF were tested. The CH2Cl2 and EtOAc fractions showed highest activities (IC50 5.47 and 3.63 μg/mL, respectively). Compounds 1-5 were isolated from the CH2Cl2 and EtOAc fractions by silica-gel and LH-20 Sephadex. Their structures were elucidated as β-sitosterol (1), diosmetin (2), kaempferol (3), luteolin (4), and apigenin (5). Compounds 1-5 were exhibited AR inhibitory. Among them, luteolin (4) and apigenin (5) exhibited AR inhibitory activities (IC50 0.40 and 1.10 μg/mL, respectively). Our results demonstrated that PF could be a worthy natural source for curing against diabetic complications.
