Objective : Herb medicines are potential sources of useful edible and medicinal plants. They are used as a drug because of their various biological activities such as immunomodulatory, antiviral, and antitumor functions. Nelumbo nucifera have been applied in Chinese herbal prescriptions to improve tissue inflammation. However, it has not been elucidated on the effect of the flower of Nelumbo nucifera in cells. Method : In the present study, to examine the effect of that on glioma cells, U87, the essential oil was extracted from the flower of Nelumbo nucifera (NN essential oil). U87 cells were exposed to different concentrations of 2-40 ug/ml of NN essential oil in ethanol. Cell viability was measured by MTT assay at 24 h. To find out the intracellular target signal molecule(s) for this antiproliferative activity of NN essential oil, phosphorylation of Akt, ERM, MAPK or p38 proteins were examined by Western blot analysis. To study long term effect of NN essential oil in U87 cells, the image of cells treated with NN essential oil for 4 days were obtained. Results and Conclusion : NN essential oil was shown to exhibit antitumor activity in glioma cells, at a broad range of concentrations of 10-40 ug/ml. The phosphorylation of Akt and Endoplasmic Reticulum Matrix (ERM) proteins which known to be involved in the cell death, were gradually decreased to 2 hours after addition 20 ug/ml of NN essential oil. However, the phosphorylation of mitogen-activated protein (MAPK) and p38 was found to increase in NN essential oil treated cells. NN essential oil treated cells showed decreased glioma cell number. These results provide a possible NN essential oil-induced inhibitory signal for tumor cell proliferation that is initiated by the decrease in Akt activity. Moreover, it is likely that the activation of p38 is required for the NN essential oil-induced inhibition of tumor proliferation.

Objectives: The study was designed to provide clinical evidence of homogeneity in analysis of the herbal medicine, Guipi decoction in treating insomnia, using a t-test of randomized controlled trials (RCTs). Methods: This study included RCTs that verified homogeneity of Guipi decoction in treating insomnia. Literature studies of CNKI (Chinese National Knowledge Infrastructure Database) were performed. The basic components group was made to the Guipi decoction of the Yixuerumen?s text. The excluded group was created with the number of herbs excluded from the basic components group. T-test performed that the effective rate in the basic components group and excluded groups. Results: The basic components of Guipi decoction contain Atractylodis Rhizoma Alba, Poria Sclerotium (Poria Sclerotium Cum Pini Radix), Polygalae Radix, Astragali Radix, Zizyphi Semen, Angelicae Gigantis Radix, Aucklandiae Radix, Glycyrrhiza uralensis Fischer, Ginseng Radix (Codonopsis Pilosulae Radix), Longanae Arillus. Herbs excluded from the basic components group were Longanae Arillus, Ginseng Radix (Codonopsis Pilosulae Radix), Glycyrrhiza uralensis Fischer and herbs added to the basic components group were Polygonum multiflorum Thunberg, Schisandrae Fructus, Salviae Militiorrhizae Radix, Paeoniae Radix Alba (in order from the most used to the least). T-test revealed the effective rate in the basic components group was not statistically significant compared to the excluded groups (p=0.161/p=0.162/p=0.103). Conclusions: Effectiveness in treatment of basic components of Guipi decoction and excluded groups were revealed to be homogeneous in treating insomnia. As the number of herbs in the basic components group decreased, mean value in effectiveness of treatment also decreased consequentially. However, there were no statistical significances.
Diospyros Kaki Thunberg is the species of persimmon tree that grows in Korea. Although its fresh or dried fruits are often served as a desert, it has little been known if persimmon tree has any specific pharmacological action. The leaves and branches of persimmon tree has long been used as folk remedies for palsy and frostbite in the southern part of Korea and it is also in use for the treatment of hiccup and nocturnal enuresis in chinese herbal medicine. Recently it was reported that an intravenous administration of Diospyros Kaki Thunberg ethanol extract (KTEE) into the animals lowered arterial blood pressure. Lee concluded from his study on the mechanism of depressor action of KTEE that at least a part of depressor response he observed was caused by acetylcholine-like action of KTEE. On the other hand little study has been made on the effect of KTEE on the motility of isolated animal intestines. Therefore the present study was undertaken to investigate effect of KTEE and the mechanism of its action on the motility of isolated rabbit duodenum. Ethanol extract of Diospyros Kaki Thunberg was prepared by boiling 1 kg of dried branches of persimmon tree in 1 liter of ethanol and the motility of isolated rabbit duodenum was recorded on physiograph by means of force transducer connected with Magnus apparatus. Doses of KTEE used were $5{\times}10^{-4}gm/ml,\;1{\times}10^{-3}gm/ml,\;and\;2{\times}10^{-3}gm/ml$. And the isolated duodenum was separately pretreated with acetylcholine $(5{\times}10^{-7}gm/ml)$, pilocarpine $(2.5{\times}10^{-6}gm/ml)$, histamine $(5{\times}10^{-6}gm/ml)$ and barium chloride $(2.5{\times}10^{-5}gm/ml)$ in order to find out interactions of these drugs with KTEE. The results obtained are as follows: 1. At doses of $5{\times}10^{-4}gm/ml,\;1{\times}10^{-3}gm/ml$ KTEE reduced contractions of isolated duodenum, while tonus as well as contaction of duodenum were depressed with $2{\times}10^{-3}gm/ml$ of KTEE. 2. Since the inhibitory effect of KTEE on the intestinal motility was not blocked by pretreatment with acetylcholine, pilocarpine, and barium chloride, it was strongly suggested that the inhibitory action of KTEE on intestinal motility is mainly Caused by its antihistamine effect. 3. It is also concluded that the principal substance of KTEE responsible for inhibition of intestinal motility may also have a vasodilating activity and would not be an acetylcholine-like substance in case it is same substance as that cause depressor responses.

In order to investigate the radioprotective effect of Si-Wu-Tang (Korean name: Sa-Mul-Tang), a kind of traditional Oriental medicine as a blood-building decoction (Oriental medical concept: Bu-Xie), and Si-Jun-Zi-Tang (Korean name: Sa-Gun-Ja-Tang), one of the widely used Oriental herbal medicines as an energy tonic (Chinese medical concept: Bu-Qi). the jejunal crypt survival, endogenous spleen colony formation, and apoptosis in jejunal crypt cells were observed in irradiated mice. Jejunal crypts were protected by Si-Wu-Tang pretreated both per os (2 mg/mL of drinking water for 7 days, p<0.05) and intraperitoneally (1 mg/head, single injection at 24 hours before irradiation). Si-Wu-Tang adminstration before irradiation(1 mg/head, single injection at 24 hours before irradiation) resulted in an increase of the formation of endogenous spleen colony (p<0.005). The frequency of radiation-induced apoptosis in intestinal crypt cells was also reduced by pretreatment of Si-Wu-Tang (p<0.01). However, the radioprotective effect of Si-Jun-Zi-Tang was not as significant as that of Si-Wu-Tang. These results suggest that Si-Wu-Tang may be a useful radioprotective food, especially since it is a relatively nontoxic natural product.
Forsythiaside is a polyphenolic constituent of the fruits of Forsythia suspense Vahl which are widely used as anti-inflammatory herbal raw materials in traditional Chinese medicine. In the present study, the authors assessed the effects of forsythiaside on learning and memory impairments induced by scopolamine using a passive avoidance and the Morris water maze tests in mice. Drug-induced amnesia was induced by scopolamine treatment (1 mg/kg, i.p.). Forsythiaside (10 mg/kg, p.o) administration significantly prevented scopolamine-induced step-through latency reduction in the passive avoidance test and scopolamine-induced increased escape latency in the Morris water maze test (p<0.05). Moreover, in an ex-vivo study, forsythiaside treatment (10 mg/kg, p.o) significantly reduced the increase of thiobarbituric acid reactive substance levels induced by scopolamine (p<0.05). Taken together, the present study suggests that forsythiaside could be useful for the treatment of cognitive impairment, and that its beneficial effects are mediated, in part, by its antioxidative properties.
The roots of Liriope platyphylla (Liliaceae) are widely used in traditional Chinese medicine. In the present study, we investigated the effects of ethanol (70%) extract of the roots of Liriope platyphylla (ELP70) on learning and memory using behavioral and immunohistochemical methods in mice. Control animals were treated with vehicle (10% Tween 80). With sub-chronic treatments of ELP70 (p.o.) for 14 days, the latency time was significantly increased compared with that of the vehicle-treated control group (50, 100 and 200 mg/kg; P<0.05). Moreover, immunopositive cells for brain derived neurotrophic factor (BDNF) were significantly increased in the hippocapmpal dentate gyrus and CA1 regions after ELP70 treatments for 14 days (50, 100 and 200 mg/kg; P < 0.05). In addition, those cells for nerve growth factor (NGF) were also increased in the hippocapmpal dentate gyrus region (50, 100 and 200 mg/kg; P<0.05). These results suggest that the sub-chronic administration of ELP70 improves learning and memory, and that their beneficial effects are mediated, in part, by the enhancement of BDNF or NGF expression.
Recent evidence has revealed the occurrence of an apoptotic phenotype in Candida albicans that is inducible with environmental stresses such as acetic acid, hydrogen peroxide, and amphotericin B. In the present study, we found that the Chinese herbal medicine Baicalein (BE), which was one of the skullcapflavones, can induce apoptosis in C. albicans. The apoptotic effects of BE were detected by flow cytometry using Annexin V-FITC and DAPI, and it was confirmed by transmission electron microscopy analysis. After exposure to 4 ${\mu}g$/ml BE for 12 h, about 10% of C. albicans cells were apoptotic. Both the increasing intracellular levels of reactive oxygen species (ROS) and upregulation of some redox-related genes (CAP1, SOD2, TRR1) were observed. Furthermore, we compared the survivals of CAP1 deleted, wild-type, and overexpressed strains and found that Cap1p attenuated BE-initiated cell death, which was coherent with a higher mRNA level of the CAP1 gene. In addition, the mitochondrial membrane potential of C. albicans cells changed significantly (p<0.001) upon BE treatment compared with control. Taken together, our results indicated that BE treatment induced apoptosis in C. albicans cells, and the apoptosis was associated with the breakdown of mitochondrial membrane potential.
Radiotherapy is an irreplaceable method of cancer treatment but, it has various side effects, especially damage to the hemopoietic system. A lot of radioprotectors have been found but they also have toxic effects. Many kinds of crude drugs(Oriental Chinese medicine)with low toxicity have been reported to promote the recovery from radiation damage. Recently, the trial to combine radiotherapy with herbal treatment of cancer patients shows a desirable result, an enhancement in recovery of the blood system.. This study was performed to determine whether prescriptions to support the healthy energy and strengthen the body resistence, Buzhongyiqi-tang and Siliu-tang, promote the recovery of splenocytes of N:GP(s) mice from radiation damage. We investigated the proliferative effect of Buzhongyiqi-tang, Siliu-tang and EIB(ethanol insoluble fraction of Buzhongyiqi-tang) on N:GP(S)mice splenocytes before or after ${\gamma}$-irradiation. We also investigated the morphology of splenocytes cultured with these herbs. Buzhongyiqi-tang and Siliu-tang promoted the proliferation of splenocytes in a concentration of 0.1 mg/ml compared with normal control(p<0.001). After 1-5Gy of ${\gamma}$-irradiation they also showed the effect of recovery of hemopoietic cells, especially in Buzhongyiqi-tang(4Gy:p<0.005; 5Gy:p<0.05). In addition, EIB(ethanol insoluble fraction of Buzhongyiqi-tang) showed the highest proliferative effect of all agents suggesting that more effective fractions could be found from crude herbs or prescriptions. These results suggest that it is possible to make use of Buzhongyiqi-tang, Siliu-tang or EIB as radio-protective agents.
In this paper, we studied what the drug name of Sang-Baik-Pi(桑白皮) Mori Cortex Radicis) is, how to collect it; and how the chief symptoms had changed in the chinese medical references and herbological literatures and formularies. Also we bibliographically analyzed in the herbological way the drugs combinated with Sang-Baik-Pi and their active principles among the prescriptions in the famous medical book; 'Dong-Ui-Bo-Gam', (東醫寶鑑) of our country. Finally, we concluded as foolow. Numerous names of botainical origin were described, but it was not recorded that San-Keun-Baik-Pi(桑根白皮) in old days is different from root bark of Morus sp. in this times. Sang-Baik-Pi has been a common designation since Ming dynasty (AD 1500). Collections of it were independent of seasons, it could effect perfectly over 10 years old. And its cork layer should be removed after collections, it was especially emphacised that root bark on ground was poisonous. The chiefly cured symptoms with Sang-Baik-Pi were constantly not different from the contents of 'Shin-Nong-Bon-Chau-Kyung'(神農本草經) in ancient times, but it has been developed since Ming dynasty. Its uses are widely extended to a surgical and dermatologic desease; rheumatis, beriberi and diabetes in this times. and its efficacies depend upon curing. Prescriptions on Sang-Baik-Pi that were prescribed in 'Dong-Ui-Bo-Gam' are there, 177 drugs combinated with it. Glycyrrhizae Radix is most frequently combinated with Sang-Baik-Pi(frequently 68%). It is proved that Armeniacae Semen, Platycodi Radix etc, in the order take strong effects on anti-tussive, anti-phlogistic, diuretic, anti-pyretic etc. It is expressed 34 times, frequently, that a dose is 3.75g, and it shows that a usual doses is 2-4g. As the above prescriptions are classified, the results is as follows, respiratory tract desease is most frequently in 69 prescriptions, the next gastrointestinal tract 13 times, diuretic 12 times, and antipyretic 11 times. Therefore, Sang-Baik-Pi contains a good remedial value chiefly of the effects upon the respiratory diseases.
Background: A set of logical criteria that can accurately identify and verify the cultivation region of raw materials is a critical tool for the scientific management of traditional herbal medicine. Methods and Results: Volatile compounds were obtained from 19 and 32 samples of Angelica gigas Nakai cultivated in Korea and China, respectively, by using steam distillation extraction. The metabolites were identified using GC/MS by querying against the NIST reference library. Data binning was performed to normalize the number of variables used in statistical analysis. Multivariate statistical analyses, such as Principal Component Analysis (PCA), Partial Least Squares-Discriminant Analysis (PLS-DA), and Orthogonal Partial Least Squares-Discriminant Analysis (OPLS-DA) were performed using the SIMCA-P software. Significant variables with a Variable Importance in the Projection (VIP) score higher than 1.0 as obtained through OPLS-DA and those that resulted in p-values less than 0.05 through one-way ANOVA were selected to verify the marker compounds. Among the 19 variables extracted, styrene, ${\alpha}$-pinene, and ${\beta}$-terpinene were selected as markers to indicate the origin of A. gigas. Conclusions: The statistical model developed was suitable for determination of the geographical origin of A. gigas. The cultivation regions of six Korean and eight Chinese A. gigas. samples were predicted using the established OPLS-DA model and it was confirmed that 13 of the 14 samples were accurately classified.
