References in the modern Korean literature in this area to the Korean medicinal plant name written in Chinese script and expressed as Sanggisaeng have been extremely confusing. This name has been considered as six species, specifically Loranthus parasiticus, Loranthus tanakae, Taxillus yadoriki, Taxillus chinensis, Korthalsella japonica, and Viscum album var. coloratum. Recently, it was suggested that sanggisaeng is not distributed in Korea; however, the plant name Sanggisaeng recorded in old Korean literature sources, such as in the Hyang-yak-chae-chwi-wol-lyeong, Hyang-yak-jib-seong-bang, and Dong-ui-bo-gam sources, among others, was identified using the name V. album var. coloratum, whereas in China, Sanggisaeng was referred to as T. sutchuenensis. The Hangeul name of Sanggisaeng had been Ppongnamugyeousali, but now the name Gyeousali is widely used.

The concentration of neurotransmitters in rat brain was determined by HPLC-ECD (electrochemical detection) method and the effects of methanol extracts of some crude drugs, such as Polygala Radix, Myristicae Semen, Zizyphi Semen, Acori graminei Rhizoma, Visci Herba, Liriopsis Tuber, Myrrha on the concentration of neurotransmitters in the ethanol-treated rat brain were investigated. By the administration of ethanol, dopamine (DA), 3, 4-dihydroxyphenyl acetic acid (DOPAC) and serotonin (5-HT) levels in frontal cortex and 5-HT level in hippocampus were significantly increased compared with the neurotransmitter levels in the brain of saline-treated rats. The ${\gamma}$-aminobutyric acid (GABA) level in frontal cortex was decreased by the same treatment. There was a tendency that the DA level in frontal cortex and striatum of ethanol-treated rats were increased by the administration of crude drug extracts. Especially, Myrrha and Visci Herba significantly increased the DA level of frontal cortex in ethanol-treated rats, while they significantly decreased the 5-HT level in the same region of the brain. GABA level in striatum of ethanol-treated rats was significantly decreased by Myristicae Semen, Visci Herba and Myrrha. These results suggest that the tested crude drug extracts have selective interaction with neurotransmitters in specified region of central nervous system.

겨우살이는 땅에 뿌리를 박아서 사는 것이 아니라 흡근(吸根)으로 살아있는 나뭇가지에 뿌리를 박아 살아가는 기생목으로서 엽록소를 가진 상록관목이다. 모든 나무들이 낙엽진 겨울에도 홀로 푸름을 유지하고 있어 신성시되고 있다. 더욱이 잔가지가 Y자로 계속 갈라져 그 끝에 육질의 앞이 프로펠러처럼 역시 Y자로 붙어 있으며, 겨울에 투명한 노란색에 가까운 콩같이 둥근 열매가 달리는 것이 특이한 모양을 했음인지 많은 민속과 전설을 낳았다. 겨우살이는 우리나라뿐만 아니라 외국에도 널리 분포하는데 우리나라에서는 겨우살이라고 부르고, 일본에서는 야도리기(기생목(寄生木)), 중국에서도 기생목 또는 동청(冬靑), 상기생 등으로 부르며 라틴어로는 Viscum, 불란서 말로는 gui, 프랑스어로는 mistel이라 하여 모두 신비한 식물로 취급하는 점만은 공통적이다.

Objectives : To investigate the effect of Taxilli Ramulus (TR) extract on bone metabolism of ethanol-treated animal model. Methods : The changes of serum calcium, calcitonin, estrogen level, a1ka1ine phosphatase activity, osteocalcin, parathyroid hormone content and urine calcium level were observed with ethanol treatment for 60 days. The results were compared with an ethanol- TR extract double treatment group. Results : We observed increment of serum osteocalcin, parathyroid hormone content, alkaline phosphatase activity and urine calcium level by chronic ethanol feed and they were recovered to near normal level with Taxilli Ramulus extract treatment. Weight gain, serum calcium level, calcitonin and estrogen content were remarkably reduced with ethanol treatment and their levels were normalized by Taxilli Ramulus extract. Conclusions : These results showed that Taxilli Ramulus extract have the ability to recover to normal in the body an abnormal calcium metabolism process due to external factors. These results suggested that Taxilli Ramulus extract have preventive effects on calcium concentration loss and osteoporosis.

This study was designed to investigate whether Loranthus parasiticus extract (LPE) could inhibit the activities of carbohydrate digestive enzymes and alleviate postprandial hyperglycemia in diabetic mice. Lyophilized L. parasiticus was extracted with 80% ethanol and concentrated. The inhibitory effects of LPE on carbohydrate digestive enzymes were evaluated by examining α-glucosidase and αamylase, and it was seen to inhibit the activities of both enzymes in a dose-dependent manner. More specifically, the IC50 values of LPE against α-glucosidase and α-amylase were 0.121±0.007 and 0.157±0.004 mg/ml, respectively, significantly lower than those of acarbose, showing that LPE has stronger inhibitory effects than the positive control. These results suggest that LPE strongly inhibits the activities of these digestive enzymes. Blood glucose levels in the control group of diabetic mice increased to 490.00±28.52 mg/dl and 474.60±25.30 mg/dl at 60 and 120 min after a meal, respectively. However, when LPE was added to starch, postprandial blood glucose levels were significantly reduced (463.0±23.73 and 418.5±24.50 mg/dl at 60 and 120 min, respectively; p<0.05). The area under the curve also significantly decreased following administration of LPE, with no cytotoxicity. These results therefore indicate that LPE could be used as an α-glucosidase and α-amylase inhibitor and delay carbohydrate digestion and, thus, glucose absorption after a meal.

Purpose: Usually college students having a strong desire for sexual behavior, thus, knowledge about sexually transmitted disease is very important to prevent infection. The purpose of this study was to assess knowledge about AIDS and STDs in the college students, and to provide a basis for sex education for them. Methods: The subjects were 86 medical students and 59 non-medical students at One University. The data were collected by self-reported questionnaire which were consisted of 19 items (8 for AIDS, 11 for STDs). Results: The frequency of experience in sexual intercourse was significantly higher in males than females (44.0% vs 7.1%, P=0.001) and in medical students than non-medical students (36.1% vs 11.9%, P=0.015). Among 19 questions, 8 questions' score were significantly higher in medical students than non-medical students. Conclusion: Medical students had higher score for knowledge about AIDS and STDs than non-medical students. However there were no difference in the knowledge according to a experience in sexual intercourse.

Objectives : The aim of this study was to evaluate the effects of Loranthus parasiticus Merr. on cell cycle and expression of related genes in HepG2 cells. Methods : The MTT assay, cell counting assay, $[^3H]-Thymidine$ incorporation assay, flow cytometric analysis, quantitative RT-PCR and western blot assay were studied. Results : In the water extract of Loranthus parasiticus Merr., inhibition of cell proliferation and DNA synthesis in HepG2 cells was seen. These inhibitory effects were due to inhibition of G l-S transition in cell cycle. After treatment with the extract, expression of cyclin D1(G1 check point related gene) was inhibited particularly in dose-dependent and time-dependent manners. Conclusion : These results suggest that the inhibition of cell cycle progression by Loranthus parasiticus Merr. in HepG2 cell is due to suppression of cyclin D1(G1 check point related gene) mRNA expression and protein synthesis.
