Objectives: This study aimed to evaluate the effects of Cuscutae Semen water extract (CS) on MCF-7 human breast cancer cells. Methods: To clarify the results, we cultivated MCF-7 cells in cell culture plates. And then we extracted each of $100{\mu}g/ml$, $300{\mu}g/ml$, $600{\mu}g/ml$ CS, gave it to MCF-7 cell. After these process we performed MTT assay to elucidate the ability of apoptosis. The result of mRNA was analyzed by RT-PCR. Results: Each of concentrated extracts CS decreased the survival rate of MCF-7 cells. CS decreased Bcl-2 which is known as a blocking cell apoptosis. Bax, caspase-3, P21 and RIP-1 that accelerate apoptogenic activity factors increased by CS. CS did not change the condition of caspase-8, caspase-9, P53 factors on MCF-7 cells. Furthermore caspase-8, caspase-9, P53 factors on MCF-7 cells does not make it more active but turn it on. Conclusions: According to the above results, we could suggest that CS can occur the apoptosis on MCF-7 cells.

Objective : This study was performed to compare anti-inflammation, anti-oxidation and anti-bacterial effects of Cuscutae Semen(CS) extracted with two kinds of solvents, ethanol and distilled water. Methods : Two kinds of CS extractions were prepared 20, 50, 100 ${\mu}l/mg$. The cytotoxicity was measured by MTT assay in Raw 264.7 cell. The anti-inflammation effect was measured by inhibitory efficacy of NO Production in Raw 264.7 cell. The anti-oxidation effect was measured by DPPH Radical scavenging ability in HaCaT cell. The anti-bacterial effect was measured by inhibition zone diameter on Propionibacterium acnes. Results : 1. Two kinds(100 ${\mu}l/mg$) of CS extraction groups had 50% cytotoxicity in Raw 264.7 cell. 2. All of CS extraction groups were not showed significantly inhibitory effect on NO production. 3. All of CS extracted with ethanol only showed dose-dependently significantly scavenging effect of DPPH radicals. 4. Two kinds of CS extractions did not have a inhibitory effect on Propionibactrium acnes. Conclusion : Two kinds(100 ${\mu}l/mg$) of CS extraction groups have 50% cytotoxicity. Two kinds of CS extractions have not the inhibitory effect on NO production and Propionibactrium acnes. CS groups extracted with ethanol only have a significantly scavenging ability of DPPH radicals. This study suggests that CS extracted with ethanol was effective in anti-oxidation.

The study was aimed to investigate the effect cuscutae semen(CS) on the vascular systems including changes in blood pressure (BP), regional cerebral blood flow(rCBF) and pial arteriolar diameter of male Sprague-Dawely rats. The changes in rCBF were determinated by laser-Doppler flowmetry, and the changes in diameter of pial arteriole were measured through a closed crainal window. 1. Blood pressure was not affected by CS in rats. 2. rCBF was increased by CS in a dose-dependent manner. 3. Pretreatment with methylene blue(Img/kg), and propranolol(1mg/kg) significantly inhibited CS induced increased in rCBF. 4. Pretreatment with indomethacin(1mg/kg) did not inhibited CS induced increased in rCBF. 5. Pial arterial diameter was increased by CS in a dose-dependent manner. These results suggest that CS causes a diverse response of blood pressure, regional cerebral blood flow(rCBF), and pial arteral diameter. The increased in rCBF is also mediated by adrenergic ${\beta}-receptor $ and guanylate cyclase.

This study was carried out to investigate effects of Cuscutae semen extract(C. S. E) on $CCI_4$-induced liver damage in rabbits and acute toxicity in mice. $LD_{50}(mg/kg)$ of C. S. E. was 7.83g/kg by intraperitoneal administration in mice. C. S. E. groups were showed more rapid recuperation than the control group intoxicated by $CCI_4$ only. SGPT activity was lowered significantly in 800mg/kg after 6 days. The levels of total cholesterol and total bilirubin and alkaline phosphatase were decreased apparently in 800mg/kg from 6 days. It is suggested that C. S. E. can be administered not only as a therapeutic agent(such as liver tonics) but also a healthy food to shorten the recovery time in liver diseases.

Objectives: Osteoporosis, which occurs after menopause, is a kind of metabolic bone disorder. It develops when the bone mass begins to decrease radically, and its main symptoms are bone fracture and height-shortening. This thesis aims at what effects the Cuscutae Semen Extract(CSE) has on the prevention of osteoporosis in SD-rat that is caused by ovariectomy. Methods: The 24 female white rats, after removing their ovaries, were divided into the Normals, the Control group, and the CSE administrated group. For the next 8 weeks, distilled water to the normals and the control, and the CSE(45.9 mg/100 g) to the CSE administrated group were given in the mouths of them. After 8 weeks the rats were sacrificed. Weight, albumin, aspartate aminotransferase, alanine aminotransferase, total-cholesterol, triglyceride, phosphorus, calcium, tetraiodothyronine, estradiol, the weight of the femur, the amount of tibia ash, the area of trabecular bone, and the thickness of trabecular bone were measured. Results: The serum analysis shows that the calcium and phosphorous of the CSE administrated group significantly increased compared to that of the control group. Aspartate aminotransferase, alkalinephosphatase, total cholesterol, tetraiodothyronine of CSE group were decreased, but not so significant. Albumin, alanine aminotransferase, triglyceride and estradiol of the group showed the tendency to increase, but the significance wasn't admitted. Regarding the variation of bone, the femur weight and the ash content of tibia, CSE group was more increased than the control group but the significance wasn't admitted. The histological observation shows that the trabecular thickness was more increased than the control group, and trabecular area increased significantly compared to those of the control group. The number of osteoclast and osteoblast area of the CSE groups decreased significantly compared to those of the control group. Conclusions: From the result of the above study, CSE should be effective for the osteoporosis cure and precaution and deeper study through bedside and clinical demonstration is much needed from now on.

The effects on memory and learning ability of the Korean herbal medicine, Xingyo-tang(XGT, 神交湯), which consists of Ginseng Radix(人蔘) 4 g, Liriopis Tuber(麥門冬) 40 g, Morindae Officinalis Radix(巴戟天) 40 g, Biotae Semen(柏子仁) 20 g, Dioscoreae Rhizoma(山藥) 40 g, Euryales Semen(?實) 20 g, Scrophulariae Radix(玄蔘) 40 g, Salviae Miltiorrhizae Radix(丹蔘) 12 g, Poria(茯神) 12 g, Cuscutae Semen(免絲子) 40 g, was investigated. The effects of XGT on learning and memory performance were examined in normal or memory impaired mice by using avoidance tests, Pentobarbital -induced sleep test, fear conditioning task, novel object recognition task, and water maze task. Hot water extract from XGT was used for the studies. Learning ability and memory are based on modifications of synaptic strength among neurons that are simultaneously active. Enhanced synaptic coincidence detection leads to better learning and memory. The XGT-treated (30 mg/100 g and 60 mg/100 g, p.o.) mice exhibit superior ability in learning and memorizing when performing various behavioral tasks. XGT did not affect the passive avoidance responses of normal mice in the step through and step down tests, the conditioned and unconditioned avoidance responses of normal mice in the shuttle box, lever press performance tests, and the ambulatory activity of normal mice in normal condition. In contrast, XGT produced ameliorating effects on the memory retrieval impairment induced by ethanol. XGT also improved the memory consolidation disability induced by electric convulsive shock (ECS). XGT extended the sleeping time induced by pentobarbital dose-dependently, suggesting its transquilizing or antianxiety action. These results suggest that XGT has an improving effect on the impaired learning through the effects on memory registration and retrieval.

Objectives : This study was performed to investigate the single oral toxicity of HBX-6 in Sprague-Dawley (SD) rats. Methods : Twenty SD rats were randomly assigned to four groups of 5 rats each and were administrated singly to female and male SD rats, as an oral dose of 2000 mg/kg. HBX-6 is a newly combined Korean herbal medicine formula 30 % Ethanol extract derived from The Dongui Bogam. Now we are developing the prescription for the aim of improving benign prostatic hyperplasia (BPH) without undesirable side effects. HBX-6 is composed of nine medicinal herbs: Aconiti Lateralis Radix Preparata, Corni Fructus, Cistanchis Herba, Psoraleae Semen, Dendrobii Herba, Morindae Radix, Cuscutae Semen, Trigonellae Semen, Foeniculi Fructus. Animals were monitored for the mortality and changes in the body weight, clinical signs, gross observation and necropsy findings for the 14 days according to "Standard for Toxicity Study of Pharmaceuticals" of Korea Food and Drug Administration (KFDA) guideline and "Acute Oral Toxicity - Fixed Dose Procedure" of OECD Test Guideline. Results : We could not find any mortality. Compared with the control group, significant weight change was not observed in the experimental group. After administration, the more common symptoms were not observed. There were no gross abnormalities in all cases. Conclusions : Taken together, these results suggest that the approximate lethal dose of HBX-6 in both female and male SD rats were considered as over 2000 mg/kg.

Purpose : The first purpose of this study is to find out whether the water extract of Rehmanniae Radix Preparat(RRP), Cuscutae Semen(CS) and their combination(Ssangbohwan, SBH) have the effect of suppressing Receptor activator of nuclear factor kappa-B ligand(RANKL)-induced osteoclast differentiation. The second purpose of this study is to find out whether the water extract of RRP, CS and SBH have the effect of inhibiting osteoporosis in an osteoporosis model induced by lipopolysaccharide(LPS). Methods : After promoting differentiation of osteoclasts by treating the RANKL, we observed the effect by the administration of RRP, CS and SBH. In addition, by means of Reverse transcription polymerase chain reaction(RT-PCR), we assayed mRNA expression levels of NFATc1, c-Fos, TRAP and GAPDHS(Glyceraldehyde-3-phosphate dehydrogenase, spermatogeni) from bone marrow macrophages(BMMs). Similarly, the protein expression levels of NFATc1 (Nuclear factor of activated T-cells, cytoplasmic1), C-Fos, MAPKs(Mitogen-activated protein kinases) and ${\beta}$-actin in cell lysates were analyzed by means of Western Blotting. Finally, we determined the anti-osteoporotic effects of RRP, CS and SBH, through the use of Lipopolysaccharide-induced bone-loss mouse. Results : RRP, CS and SBH showed remarkable inhibitive effect on RANKL-treated osteoclast differentiation without cytotoxicity. SBH inhibited the phosphorylation of p38, Jun N-terminal kinases(JNK), and I-${\kappa}B$ and down-regulated the induction of c-Fos and NFATc1 by RANKL. RRP, CS suppressed degradation of I-${\kappa}B$, but it did not affect c-Fos and NFATc1 by RANKL. Lastly, in vivo data showed that RRP and SBH prevented bone erosion by LPS treatment. Conclusions : These results demonstrate SBH can be effective remedy for bone-loss diseases such as osteoporosis.

According to the traditional chinese herbal Cuscuta japonica Choisy and C. australis R.Be (original plant of Semen Cuscutae in Korea) have been used to cure pimple. In order to prove their bacteriostatic effects against Propionibacterium acnes, we performed the micro broth dilution method. The minimal inhibitory concentration (MIC) of C. japonica juice was 27.3 mg/ml, but C. australis juice showed no effect. The MIC of water extracted C. japonica seed and Wontosa and Bupjetosa were $960\;{\mu}g/ml$. The MIC of both water and ethanol extracts of C. australis seed was $9240\;{\mu}g/ml$. But ethanol extracts of C. japonicaseeds, Wontosa and Bupjetosa had no bacteriostatic activity. We also performed the disk diffusion test, C. japonica juice had prominent effect. Water extracts of C. japonica seed, Wontosa and Bupjetosa showed bacterio-static effect in 10 mg/ml, and C. australis seed in 10 mg/ml. The ethanol extract of C. japonica seed, Wontosa and Bupjetosa, and C. australis seed showed bacteriostatic effect in 20 mg/ml.
