  • To establish an efficient herbicide screening method for purple nutsedge(Cyperus rotundus) control, its sprouting characteristics, tuber production and responses on several herbicides were investigated under greenhouse condition. The tubers stored at $4^{\circ}C$ after sterilization with the diluted prochloraz(Spotac) solution showed higher sprouting than the non-sterilized did. The harvested tubers were not dormant, and the sterilized tubers which stored at low temperature had a sprouting capability of about 80% after 6 months. If the fresh weight of purple nutsedge tubers was decreased to below 48%, they could not sprout. However, the tubers soaked in water and then stored at low temperature could sprout by 88% even 6 months later. Sprouting and initial growth of tuber were much better at $35^{\circ}C$-day/$25^{\circ}C$-night than at 30/$20^{\circ}C$ or 25/$15^{\circ}C$. The half-sected tubers, which were prepared by setting the intact tuber of above 1.2g latitudinally, were shown similar initial growth to the intact but those sected crucifically were not. These results suggest that the half-sected tuber itself can be used as a material on herbicide screening. About 1000 tubers could be harvested when 10 tubers planted in a pot($56{\times}35{\times}16cm$) filled with the artificial soil were cultivated in greenhouse of $35^{\circ}C$-day/$25^{\circ}C$-night for 3 months(April-July, 1993). Chlorimuron, Bentazon and Norflurazon were selected as the standards for the screening because of providing relatively effective control on purple nutsedge in both soil-surface and foliar spray treatment.

  • Objectives: This study was performed to review the research trends regarding the treatment of Postpartum Depression (P.P.D) in the Traditional Chinese Medicine (TCM). Methods: We searched articles in CNKI (China National Knowledge Infrastructure) from 2004 to 2013. Search key words were "产后抑郁症", "Postpartum Depression", and we selected 27 studies except for non-clinical studies, insufficient number of studies, unrelated studies and tests on animals. Results: We selected 27 articles with following results: 1) One study of Jadad Quality Assessment Scale score showed 3 points, 4 studies showed 2 points and 22 studies showed less than 1 point. Overall, the quality of the studies was low. 2) DSM - IV was frequently used as a diagnostic criteria and HAMD was mostly used as evaluation criteria. Diagnostic criteria and evaluation criteria were the same in HAMD and EPDS. 3) In TCM, there are various ways, such as herbal medicine, acupuncture, electro acupuncture, auricular acupuncture and/or massage to treat the postpartum depression. 4) The roots of Bupleurum falcatum Linne, Glycyrrhiza uralensis Fisch, Angelica gigas Nakai and Paeonia lactiflora Pall, the rhizome of Atractylodis macrocephala Koidz, the semen of Zizyphus jujuba Mill, the radix of Curcuma aromatica Salisb, the sclerotium of Poria cocos Wolf and the rhizomas of Cyperus rotundus L and of Cnidium officinale Makino are mainly used in the herbal medicine. BaekHoi (GV20) and Yindang (Ex-HN3) are mainly used in acupuncture points. 5) Most of the studies showed effective results. Some of the results were similar to those of the control groups which were cured by western medicine. Other results were better than those of control groups. Conclusions: Research on postpartum depression has been actively conducted in TCM and all studies showed effective results in the study group patients. Therefore, with this study, we hope to activate more clinical research on the treatment of patients in Korean traditional medicine.

  • For screening antimutagenic effects, the effects of 95 medicinal plants on the mutagenicity of aflatoxin $B_1$ $(AFB_1)$ and benzo(a)pyrene [B(a)P] were investigated using the SOS chromotest with Escherichia coli PQ37. The mutagenicity induced by $AFB_1$ or B(a)P was reduced over 26% by 2 kinds and 8 kinds of medicinal plant, respectively. Eight plants (Bupleurum falcatum, Corydalis ternata, Gasfrodia elata, Ostericum koreanum, Pinellia ternatia, Poncirus trifoliata, Prunus armeniaca and Rehmannia glutinosa) were also shown to have inhibitory effects on both $AFB_1$ and B(a)P. The mutagenicity induced by $AFB_1$ or B(a)P was increased over 20% by 46 kinds and 2 kinds, respectively, and 8 medicinal plants (Chrysanthemum indicum, Cinnamomum cassia, Cyperus rotundus, Morus bombycis, Patrinia scabiosaefolia, Petasites japonicus, Polygonum multiflorium, Thyja orientalis) increased significantly the mutagenicity of both mutagens. However the 8 plants themself did not show the mutagenicity in SOS Chromotest with S-9 mix alone. This result suggests that the above 8 plants may have the co-mutagenic activities. In two bacterial mutation system, SOS Chromotest and Ames test, the mutagenic or antimutagenic activities of some medicinal plants wire similar except Ostricum koreanum, Eugenia caryophyllata and Scutellaria baicalensis.

  • Despite the development of assisted reproduction technologies (ART) including in vitro fertilization (IVF), the poor ovarian response and endometrial receptivity remains clinically a major unmet need. Although these problems are difficulties to solve in infertility treatment, there are no good therapeutic option yet. Traditional herbal remedies and acupuncture, therefore are being proposed as alternative treatment. Our group found that traditional herbal medicines such as Paeonia lactiflora L.(PL, 芍藥), Cyperus rotundus L.(CR, 香附子), and Perilla frutescens (PF, 紫蘇葉) could improve endometrial receptivity. In this study, we found out Yeosin-san (如神散) as an optimal herbal formula via combination of the previously established herbal medicines. Yeosin-san is a traditional Korean medical formula which was established by Ziming Jin (陳自明) and recorded in Furendaiquanliangfang (婦人大全良方) at first. The formula traditionally used for treating abnormal uterine bleeding and leukorrhea. It showed a highest effect on leukemia inhibitory factor (LIF) expression and on the adhesion between trophoblastic cells and endometrial cells. In addition, it has been shown that the Yeosin-san not only increases the endometrial receptivity to improve the embryo implantation but also enhances the ovary function by expressing the angiogenesis-related genes. Here we suggest that Yeosin-san could be a novel and effective candidate for treating female infertility.

  • Objectives: The purpose of the present study is to investigate anti-depressive effects of Samul-tanggahyangbuja (SGH) on ovariectomized and chronic mild stress (CMS) induced rats. Methods: Ovariectomized rats were exposed to CMS for 4 weeks. Changes of depression behavior were tested by using sucrose intake test (SIT), elevated plus maze (EPM), forced swimming test (FST) and Morris water maze test (MWMT) in rats until being orally medicated with SGH (100 or 400 mg/kg/day). In addition, the serum levels of corticosterone (CORT), IL-4, IL-$1{\beta}$ and changes of 5-HT in the brain were measured. Results: 1. SGH 400 mg/kg treated group (SGH 400) significantly increased amount of sucrose intake compared with the control group (p<0.05). 2. SGH 100 mg/kg treated group (SGH 100) and SGH 400 significantly increased the time spent in the open arms of the EPM compared with the control group (p<0.01). SGH 400 also significantly increased the number of crossing of the open and closed arms compared with the control group (p<0.05). 3. SGH significantly shortened the immobility time in FST compared with the control group (SGH 100 p<0.05, SGH 400 p<0.01). 4. SGH significantly increased performance of acquisition trials compared with the control group (p<0.05, on day 4, 5 of SGH 100 and 400). SGH 400 also significantly increased performance of retention trials compared with the control group (p<0.05). 5. The serum levels of corticosterone and IL-4 were not significantly different among the groups. There were no changes on the serum levels of corticosterone, IL-$1{\beta}$ and IL-4 after administration with SGH. 6. SGH 400 significantly increased the level of 5-HT in the hippocampus compared with the control group (p<0.05). SGH significantly increased the levels of 5-HT in the hypothalamus compared with the control group (SGH 100 p<0.05, SGH 400 p<0.01). Conclusions: These results suggest that SGH has the anti-depressive effect on ovariectomized rat and affect 5-HT system rather than hypothalamic-pituitary-adrenal (HPA) axis and immune system.

  • To produce bioactivity-strengthen medicinal herbs, the 36 medicinal herbs which have antioxidation or blood circulation activity, were solid fermented using Phellinus baumii mycelium. Most of medicinal herbs, except Chrysanthemum indicum (flower), Zizyphus jujuba Miller (fructus), Aconitum koreanum R. Raymond (root), Magnolia denu-data (flower), and Polygonatum sibiricum Redt (root bark), showed good fermentation at $25^{\circ}C$ for 20 days under 90% of relative humidity. The poor fermentations of the herbs could be explained by lack of nutrient, structural rigidity, and the content of antifungal substance. After fermentation, the average water content of herbs were increased to $67.21{\pm}11.43%$ from $30.84{\pm}15.67%$, but the average pH and average methanol extraction ratio were slightly decreased to $11.16{\pm}7.06%$ and $4.83{\pm}0.73$ from $13.91{\pm}12.22%$ and $5.06{\pm}0.87$, respectively. The analysis of thrombin inhibition and DPPH scavenging activity of the methanol extracts of herbs showed that thrombin inhibition activities of the fermented Drynaria fortunei Kunze, Melia azedarach var. japonica, Prunus persica and Orostachys japonicus, and DPPH scavenging activities of the fermented Polygala tenuifolia, Scrophularia buergeriana, Angelica dahurica, Drynariafortunei Kunze, Cyperus rotundus, and Boschniakia rossica were increased as compared with those activities of non-fermented its cognate herbs. Our results suggest that the production of bioactivity-strengthen medicinal herbs is possible by solid fermentation of Phellinus baumii mycelium, as fermented Drynaria fortunei Kunze showed increased antioxidant and thrombin inhibitory activities than those of non-fermented herbs.

  • Identification of natural compounds that can prevent the development of obesity in vivo is time consuming and expensive. We have used in vitro systems derived from pig adipose tissue to screen simple aqueous or ethanolic extracts of Korean medicinal herbs (KMH) for their anti-adipogenic potential. A total of 183 extracts were tested for their actions in lipogenesis of pig adipose tissue and differentiation of pig preadipocytes. Ethanol extracts were prepared from 72 and aqueous extracts were prepared from 111 medicinal herbs. Both an ethanolic and an aqueous extract were prepared from 65 of these. Thirteen extracts substantially altered rates of lipogenesis in vitro. The effects of KMH on lipogenesis of pig adipose tissue are as follows. Elevens reduced lipogenesis to rates that were more than 40% lower than control and four of these reduced rates of lipogenesis by more than 70%. The most potent anti-lipogenic extracts were those obtained in ethanol from Iridaceae and from Sophora flavescens AIT as well as both the aqueous and ethanolic extracts from Lysimachia vulgaris L. Two extracts, those prepared in water from Caesalpiniae lignum and from Phellodendri cortex, were found to promote rates of lipogenesis in vitro. The effects of KMH on differentiation of pig preadoipocytes are as follows. Twentyeight extracts altered the rates of differentiation of cultured porcine preadipocytes. Sixteen increased and twelve reduced the rates of differentiation of preadipocytes. Extracts prepared in ethanol from Moutan radicis cortex and from Ostericum koreanum and those prepared in water from Angelicae gigantis radix, from Inula henenium L and from Magnolia flos doubled the rate of differentiation of cultured porcine preadipocytes. Ten extracts reduced the in vitro rate of differentiation of porcine preadipocytes by more than 35%. These were the ethanolic extracts from Glycyrrizae radix, Nepetae spica and from Polygala myrtifolia and the aqueous extracts from Amaranthaceae, Asparagus cochinchinesis, Atractylodis rhizoma alba, Citrus junos TANAKA, Cyperus rotundus, Epimedium grandiflorum and from Moutan radicis cortex. Only the ethanolic extract from Polygala myrtifolia was able to both reduce lipogenesis in adipose tissue slices and retard differentiation of cultured preadipocytes. The results of our study will provide meaningful information to identify medicinal herbs which would reduce fat deposition in livestocks and humans.
