In our country, patients with diabetes mellitus are searching for complementary treatments to recover from illness, while they received treatments from the doctor. However, have been evaluated or investigated systematically. This study was carried out to explore application of complementary treatments for patients with DM. For this survey, questionnaires were developed by researchers and the data was collected from July to October of 1999. Among the 223 subjects, there is one general hospital, one oriental hospital, 15 area C.H.P, ahd 2 area health centers. The results were as follows: 1. The total number of cases was 223 and the average age was 62.85 years old and average duration of DM was 8.1 years. The number of patients who had experience with alternative therapies was 145 (65%). The number of those who have not undergone treatments was 78 (35%). 2. The 43.5% of experienced CAM were advised family and relatives. Only 30.3% approved the effect of CAM and 52.5% said that If another a new CAM is introduced, they will try it. 4. Ninety three kinds of complementary treatments were used. Among the used items, 63.7% was various types of plants, 21.6% was animal material and 14.7% was the mixed group. As a single item, Bombyx Mori (Silkworm) was the most frequently used (10.5%) followed by the bean, mushroom, Morus bombycis (mulberry), Ginseng, Commelina Communis (Dalgaebi), Chinese medicine, root of Rosa rugosa (Haedangwha). 5. Among the used items, Trichosanthes kirilowii Max. Eucommia ulmoides Oliver, Commelina Communis, Aralia elata, pine needle, mulberry fruit, root of Rosa rugosa. Ginseng, Lycii Fructus, Dioscorea radix, Polygonatum odoratum, Cassia tora L, Bombyx Mori, loach, Crucian carp were based upon the pharmacological function of effect for control of diabetes mellitus symptom. 6. In the analysis of the relationships between the general characters of the patients with new complementary alternative medicine try and hospital treatment; 1) The shorter group suffered from DM (p=.038), poor Self-MBG (p=.037) and wanted to try new complementary alternative medicine. 2) The group of DM education experience were carried out hospital treatment well (p=.045). In conclusion, further study will be required for the patients experience using alternative therapies as the D-M in terms of holistic view of patients.

The objective of this study is screening the anti-oxidative effects of several plant MeOH extracts against oxidative stress in Neuroblastoma cell. Oxidative stress has been implicated in the pathogenesis of many neurotoxicity, neurodegenerative disorders and cell death. This oxidative stress is generated by ROS (Reactive Oxygen Species) such as nitric oxide, nitrogen dioxide, peroxyl, superoxide ($O_2^-$), hydroxyl, alkoxyl. So, in the present study, we induced oxidative stress by treatment of sodium nitroprusside (2.5 mM) in human neuroblastoma SH-SY5Y cell which was treated samples before 24hr, and cell viability was measured by MTT reduction assay. Of those tested, the extracts of Paeonia japonica (roots), Eucommia ulmoides (炒)(barks), Paeonia japonica (曝乾)(roots), Phyllostachys bambusoides (stems), Polygala tenuifolia (去心, 炒)(roots), Paeonia japonica (roots), Polygala tenuifolia (roots), Machilus thunbergii (barks), Mallotus japonicus (leaves), Poria cocos (whole), Sophora flavescens (roots), Angelica tenuissima (roots), Angelica gigas (當歸尾)(roots) showed anti-oxidative effects[$EC_{50}$<15.20 ${\mu}g$/ml(Carnosine:Positive control)]in dose dependent manner.

Methanol extract (MeOH), n-hexane (Hx), chloroform ($CHCl_3$), ethyl acetate (EA), butanol (BuOH) and aqueous ($H_2O$) fractions of Eucommiae Cortex including geniposidic acid (GA), geniposide (GP) and aucubin (AU) were tested for their therapeutic efficacy on osteoporosis. The contents of GA, GP and AU in the cortex and leaf of Eucommia ulmoides Oliver were quantified by HPLC. The effect of Eucommiae Cortex on the induction of growth hormone (GH) release was studied by using rat pituitary cells. The proliferation of osteoblast-like cells increased by herbal extracts was assayed using a tetrazolium (MTT), alkaline phosphatase (ALP) activity, and [$^3H$]-proline incorporation assays. The inhibition of osteoclast was studied by using the coculture of mouse bone marrow cells and ST-2 cells. As a result, the GA, GP and AU were present in the cortex more than in the leaf of E. ulmoides Oliver. The MeOH (1mg/mL), Hx, $CHCl_3$ and EA fractions (each 20 $\mu$ g/mL) had potent induction of GH release. The $CHCl_3$ exhibited the potent proliferation of osteoblasts. The AU, GP and GA were increased proliferation of osteoblasts. In addition, GA ($IC_{50}: 4.43{\times}10^{-7}$M), AU and GP were significantly inhibited proliferation of osteoclast. In summary, it is thought that the components in a part of the fractions of Eucommiae Cortex participate in each step of mechanism for activating osteoblast to facilitate osteogenesis, and suppress osteoclast activity to inhibit osteolysis.

Bone is continuously remodeled by osteoblasts and osteoclasts. We investigated the effects of medicinal herbs, which act on bone metabolism. Fifteen kinds of medicinal herb extracts were screened for bone formation activity with osteoblastic cells, and MC3T3-E1 and bone resorption were screened with osteoclasts derived from mouse bone marrow macrophages. Among these samples, Actinidia polygama, Eucommia ulmoides Oliv., Schizonepeta tenuifolia, Sorbus commixta, and Zingiber officinale Rosc. extracts showed strong bone-forming activity accompanied with osteoblast proliferation and alkaline phosphatase activity. In addition, these extracts decreased tartrate-resistant acid phosphatase activity against osteoclast differentiation. The results indicate that these medicinal herb extracts can potentially prevent bone-related diseases such as osteoporosis by increasing osteoblast differentiation and reducing osteoclast activity.

Objectives SJ004 is a natural herbal medicine that contains Acyranthes japonica Nakai and Eucommia ulmoides Oliver traditionally used for joint and spinal diseases. This study aimed to establish an efficient method of extracting SJ004 to standardize using the yield, high-performance liquid chromatography (HPLC), and antioxidant assay. Methods SJ004 was extracted with distilled water, 70% and 100% of ethyl alcohol (EtOH). The method validation of 20-hydroxyecdysone and pinoresinol diglucoside was determined by HPLC-photo diode array and the content of SJ004 was calculated. The antioxidant activity of each extract was compared and measured using total flavonoids, total phenolic compounds, 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), and ferric reducing antioxidant power according to the standard protocol. Results The yield was highest in pure water extract and lowest in 100% EtOH. But, the content of marker compounds indicating 20-hydroxyecdysone and pinoresinol diglucoside was highest in 100% EtOH extract. In the physiological activity measurement using antioxidant activity, 100% ethanol extract was highest. The limit of detection indicating 20-hydroxyecdysone and pinoresinol diglucoside were analyzed 0.33 ㎍/mL, 0.1616 ㎍/mL, and the limit of quantification were analyzed 1.01 ㎍/mL and 0.49 ㎍/mL respectively. Conclusions The experimental results showed that the extraction conditions have a significant effect on content of marker compounds and antioxidant activity. As a result of method validation, SJ004 was standardized by 20-hydroxyecdysone and pinoresinol diglucoside.

Survey on the status of cultivation and production of medicinal crop was studied on 18 medicinal herbs and 5 medicinal trees in 66 major crop producing complexes. Native seeds or seedlings of the crops obtained from self-seed or neighbored farmer were cultivated and organic fertilizer was preferred to chemical fertilizer in the complexes. More than 60.7% of farmers were applied compost among the organic fertilizers, while 34.8% of them cultivated without any organic fertilizers. Both of using the compound chemical fertilizers and urea and urea only used were showed 51. 5% and 40.9%, respectively. Ostericum koreanum, Angelica gigas, Phellopterus littoralis, and Bupleurum fulcatum belonging to the family Umbeliferae and Aralia continentalis, Polygonatum sibiricum and Eucommia ulmoides in the complexex were not damaged by insect pests and plant diseases. Mite, aphid, grub, cutworm, onion magot fly and european corn borer were known to as major insect pests and anthracnose, powdery mildew, brown leaf spot, leaf blight and root rot as major plant diseases. Productivity and income of a farm by medicinal crops in the complex were greatly different from seeding time, planting distance, year yielded, and selling routes even in the same cultivation method and in the same cultivated area.

This study was conducted to evaluate the rehabilitation measures and select appropriate tree species and rehabilitation methods for rehabilitating the rock desert areas in Guizhou, China. The study was carried out during the periods from 2003 to 2006 and results are as follows. Afforestation site is classified as a dolomite sandstone hilly country, a halfstony hilly country, a karst physiognomy, a rock desertification farmland and an latent rock desertification farmland by soil type and rock desertification status. Total afforestation area of Xuiwen is 1,300ha and afforestation area of a dolomite sandstone hilly country, a halfstony hilly country, a karst physiognomy, a rock desertification farmland and an latent rock desertification farmland are respectively 104.0ha (8.0%), 146.6ha (11.3%), 200.5ha (15.4%), 705.7ha (54.3%) and 143.2ha (11.0%). Planted tree species were selected by five site types. Robinia pseudoacacia, Chamaecyparis obtusa, Thuja orientalis, Cupressus duclouxiana and Juniperus chinensis L. var. chinensis were planted in a dolomite sandstone hilly country and Choerospondias axillaris and Robinia pseudoacacia were planted in a halfstony hilly country. Cupressus duclouxiana, Zanthoxylum bungeanum, Lonicera fulvotomentosa, Ilex kudincila, Quercus aliena, Quercus variabilis, Choerospondias axillaris, Koelreuteria bipinnata, Cryptomeria japonica, Cinnamomum camphora and Cinnamomum bodinieri were planted in a karst physiognomy. Cupressus duclouxiana, Toona sinensis, Robinia pseudoacacia, Lonicera fulvotomentosa, Eucommia ulmoides, Ilex kudincha. Zanthoxylum bungeanum and Magnolia officinalis were planted in a rock desertification farmland. Lonicera fulvotomentosa, Juglans sinensis, Pyrus pyrifolia, Choerospondias axillaris, Prunus salicina and Diospyros Kaki was planted in an latent rock desertification farm land. Robinia pseudoacacia showed high survival rate in 2004 and 2005, but Zanthoxylum bungeanum and Cinnamomum camphora showed slightly low survival rate in 2004. Survival rate of planting species in 2005 was over 80% because some species which showed low survival in 2004 were changed with other species and a proper afforestation method was applied. Growth rate of tree species was evaluated by height and diameter growth rate. Cupressus duclouxiana showed a highest height growth rate in 2004. Toona sil1ensis, Choerospondias axillaris, Koelreuteria bipinnata, and Cinnamomum camphora showed almost 100% height growth rate in 2005, although they showed a negative height growth rate in 2004. Robinia pseudoacacia showed a good growth rate in the rock desertification farmland and the halfstony hilly country so it could give a commercial benefit like honey as well as an afforestation effect.
