Enzymes involved in catecholamine synthesis are present in the highest concentration in the adrenal medulla, however they were found also in other, mainly nervous tissues. Increased transcription of genes for catecholamine biosynthetic enzymes is an important mechanism to increase the capacity for epineprine/norepinephrine biosynthesis with stress. Gastrodia elata(Chinese name: Tienma), are very important Chinese herbal medicines used for the medical treatment of headaches, migraine, dizziness, epilepsy, rheumatism, neuralgia, paralysis and other neuralgic and nervous disorders. Immobilize stressed rat markedly increased tyrosine hydroxylase (TH) mRNA and dopamine-${\beta}$-hydroxylase (DBH) mRNA transcriptior level more than control group. But treated Gastrodia elata extracts in immobilized stressed rat slightly increased TH mRNA and DBH mRNA transcription level more than normal group. In addition, we are obtained identical results in PC12 cell line. Decrease of transcription level of TH mRNA and DBH mRNA is indicating that Gastrodia elata have a anti-stress effects which decrease the transcription level of TH and DBH mRNA on catecholamine biosynthesis pathway.

This study evaluated the effects of Dioscorea batatas and Gastrodia rhizoma on fatty acid composition of serum, liver and brain in rats which were fed control diet adding 5%, 10%, 15% Dioscorea batatas powder and 5%, 10%, 15% Gastrodia rhizoma powder for 3 weeks, respectively. In the other total fatty acid composition of serum lipids, the percentage of SFA was higher in the control group than in the other groups. The percentages 18:2 and 20:4 in serum lipids were significantly higher in the group 5, 6 and 7 than control group. In phospholipid fatty acid composition of serum lipids, the percentage of 18:2 was significantly higher in the group 5, 6 and 7 than in the other groups. 16:0, 18:0, 18:1, 18:2 and 20:4 were the main fatty acid in the total fatty acid and phospholipid fatty acid composition of liver lipids. 16:0, 18:0, 18:1, 18:2, 20:4 and 22:6 were the main fatty acid in the total fatty acid and phospholipid fatty acid composition of brain lipids.

Crude oils in the rhizoma of fresh and dried Gastrodia elata were obtained by a simultaneous steam distillation and extraction(SDE) method using n-pentane/diethyl ether (1 : 1) as solvent, and their volatile constituents were analyzed by gas chromatography-mass spectrometry(GC/MS) A total of 39 volatile flavor constituents (11 acids, 13 alcohols,6 hydrocarbons,7 carbonyls,2 esters) and 25 constituents (6 alcohols, 13 acids, 4 hydrocarbons, 1 carbonyl, ester) were identified in the fresh and dried Gastrodia elate respectively. The major volatile components of the fresh and dried sample were hexadecanoic acid(66.78%, 50.72%), 9-hexadecenoic acid(8.07%, 9.58%), heptadecanoic acid(2.01%, 0.13%), pentadecanoic acid(6.41%, 4.94%), p-cresol(1.43%,0.52%) and cyclododecene(1.83%, 6.00%).

본 연구는 천마를 인공적으로 재배하기 위하여 Armillaria속균을 수집하였으며 천마재배지를 조사하여 우수한 균주를 선발하기 위하여 본 실험을 실시하였다. 현재 천마 재배지에서 가장 우수한 균주는 KNU-A110, KNU-A234, KNU-A1022, KNU-A1030 등 4균주로 조사되었다. 재배지의 토양에 깊이는 $10cm{\sim}19cm$가 천마의 생산이나 Rhizomorph의 형성에 가장 적당한 것으로 조사되었다. 일본에서 5종 16균주, 미국에서 11종 22균주, 프랑스에서 6종 26균주, 아프리카에서 1종 4균주를 분양 받았으며 1994년도에 우리 나라에서 21균주를 분리하였다. 대부분의 균주가 레몬을 첨가한 배지에서 왕성하게 Mycelial fan을 형성하였으며 A. mellea인 KNU-A997 균주에서 병원성이 있는 것으로 나타났고 A. gallica인 KNU-A110 균주에서는 병원성이 검정되지 않았다. 종균 제조배지의 첨가물로는 Ethanol $0.25%{\sim}0.5%$가 우수하였으며 농가 부산물의 첨가로는 밀기울과 옥수수속의 첨가에서 효과가 있었다. 액체 접종원은 배양속도를 빠르게 할 뿐 아니라 오염률을 현격히 저하시키는 것으로 밝혀졌다.

천마의 불쾌취 개선을 위한 당화방법별 유산균 발효 결과는 3일 발효시 엿기름과 쌀누룩 이용 당화에서 총 산도가 각각 2.23, 2.33%이었으며, 생균수는 9.14 log cfu/mL와 9.27 log cfu/mL로 높았다. 발효기간이 길어짐에 따라 총 산도는 계속 높아져 3.35%까지 증가하였으나, 생균수는 3일 발효에서 가장 많았다. 아미노산 함량은 엿기름과 쌀누룩 이용 당화에서 높았고, 유리당 함량은 효소 이용 당화에서 높았으며, 그 중 glucose 함량이 가장 높았다. 천마 주성분인 gastrodin, p-HBA 등 주 성분 함량도 효소 이용 당화에서 가장 높았다. 이취성분인 p-cresol 함량이 엿기름 이용 당화에서 낮아 관능평가 결과에서도 엿기름을 이용하여 당화한 유산균 발효천마가 가장 좋은 기호도를 나타내었다.

MeOH extract of Gastrodia elata was fractionated to five solvent fractions, hexane fr (fr I), 90% MeOH fr (fr II), EtOAc fr (fr III), BuOH fr (fr IV) and $H_2O$ fr (fr V). Among the five fractions, fr II, III and IV showed platelet anti-aggregating effects against ADP or collagen induced rat platelet aggregation in vitro. Fr II , III and IV were also tested in vivo, in the mouse and rat models of thrombosis. Oral administration of fr II, III or IV enhanced the recovery from the thrombotic shock in the mouse model of thrombosis to 32-40% from 17% of recovery with the control group of mice. Treatment with fr II, III or IV also attenuated the sudden reduction in the blood platelet count following intravenous collagen injection to rat. The above results were indicative of the presence of anti-platelet and anti-thrombotic components in this plant.

It remains to be determined whether there is a geographical distribution pattern and phylogenetic signals for the Mycena strains with seed germination of the orchid plant Gastrodia elata. This study analyzed the community composition and phylogenetics of 72 Mycena strains associated with G. elata varieties (G. elata. f. glauca and G. elata. f. viridis) using multiple gene fragments (ITS+nLSU+SSU). We found that (1) these diverse Mycena phylogenetically belong to the Basidiospore amyloid group. (2) There is a phylogenetic signal of Mycena for germination of G. elata. Those strains phylogenetically close to M. abramsii, M. polygramma, and an unclassified Mycena had significantly higher germination rates than those to M. citrinomarginata. (3) The Mycena distribution depends on geographic site and G. elata variety. Both unclassified Mycena group 1 and the M. abramsii group were dominant for the two varieties of G. elata; in contrast, the M. citrinomarginata group was dominant in G. elata f. glauca but absent in G. elata f. viridis. Our results indicate that the community composition of numerous Mycena resources in the Zhaotong area varies by geographical location and G. elata variety. Importantly, our results also indicate that Mycena's phylogenetic status is correlated with its germination rate.

Objectives : This experimental study was designed to investigate the inhibitory effects of combination with Korean red ginseng and Gastrodia rhizoma on vascular dysfunction in high-fat/cholesterol diet-induced hyperlipidemia. Methods : Sprague-Dawley rats were fed with 7.5% cocoa butter and 1.25% cholesterol for 10 weeks, with Panax ginseng (PG), and mixtures of Panax ginseng and Gastrodia rhizoma (PGM), respectively. Results : Chronic treatment with PG and PGM significantly decreased body weight. The aortic expression of cell adhesion molecules such as intracellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin were markedly increased in hyperlipidemia rats. Interestingly, PGM significantly decreased cell adhesion molecules expression. However, there was no significant decrease in PG group. In addition, PG and PGM group inhibited high-fat/cholesterol diet-induced cytokine such as monocyte chemoattractant protein (MCP-1) mRNA expression. Furthermore, PG and PGM group significantly decreased c-reactive protein protein (CRP) level. Especially, PGM significantly accentuated the decrease of MCP-1 mRNA expression and CRP level. Conclusions : the present study provides an evidence that combination with Panax ginseng and Gastrodia rhizoma enhances anti-vascular protective effects through suppression of vascular inflammation in hyperlipidemic rats.
