The Chonmachong (Tumulus No. 155 in Whangnam-dong, Kyungju, Korea), which was unearthed in 1973, is an ancient tomb built in the Shilla Era between the 5th∼6th centuries by the method of Juk-suk-mok-gwak. With the excavation of this tomb more than 11,500 articles of luxurious and splendid relics including gold and silver ornaments, weaponry and horse gears were obtained. Among the excavated articles, the saddle flap with a drawing of flying horse on it is the first relic of its kind from the Shilla Era. and 'Chonma'(a flying horse), the name of the tomb. was named after this drawing. The saddle flap is highly valuable in that it provides the idea of how goad the people of Shilla were at drawing. Although a lot of researches have been released about the relics from the Chonmachong, this study is to focus on the fabrics from the excavation, all of which are in the Kyongiu Museum's collection. The findings of this study are as follows : 1 The subject of this study is mainly on the fabrics used in horse gears, the pieces of cloth that were used to spread on a saddle or to underlay beneath a saddle. As the Shilla Dynasty tried to restrict excessive ornamentation on horses and it is assumed that the fabrics used are different. according to the social status. 2. The subject articles are four plain fabrics, three fabrics of combined -construction and one braid, the warp-faced compound woven silks of combined-construction was found for the first tinge in Korea, and is the typical quality sick with patterns woven with dyed threads in different colors. 3. It is ascertained by the Chonmachong excavation that polychrome woven silk was used not only for the clothes of the upper classes but also for the ornaments of their horses in the Era of the Three Kingdoms.

This study was performed to study the effects of Gastrodiae rhizoma on lipid concentration of serum and liver in rats fed high fat diet. Male Sprague-Dawley rat were randomly assigned to 5 groups such as basal diet only(BDG), high fat diet(HFG) and high fat diet with 5% processed Gastrodiae rhizoma(GRL), high fat diet with 10% processed Gastrodiae rhizoma(GRM), high fat diet with 15% processed Gastrodiae rhizoma(GRH) supply each of the experimental diets for 6 weeks. Food intake was significantly decreased by both high fat intake and high fat with Gastrodiae rhizoma intake compared with basal diet intake but weight gain was not significantly different from each groups. Liver weights were significantly lowered by Gastrodiae rhizoma intake compared with high fat intake. In the serum, total cholesterol was not significantly different with each groups, but triglyceride level was significantly lowered by Gastrodiae rhizoma intake as compared with control. In the liver, lipid levels inceased with the Gastrodiae rhizoma intake, but total cholesterol and triglyceride levels were not significantly different with control. These results showed that dietary Gastrodiae rhizoma as supplementary food may decrease triglyceride in the serum.

This study was carried out to investigate the effect of mixture of Gastrodiae rhizoma (GM) on blood amelioration in high cholesterol-diet rats. Sprague-Dawley male rats were randomly assigned to one normal diet and three high cholesterol-diet groups which contained 1 % (w/w) cholesterol diet. The groups of high cholesterol-diet were classified to control (high cholesterol-diet only), GM-1 (high cholesterol-diet and GM) and ST-1 (high cholesterol-diet and Statin drug). The body and organs weight were not significantly changed among the tested groups. Contents of serum total cholesterol and LDL-cholesterol were significantly increased in cholesterol-diet groups compared with normal diet group but significantly decreased in the group of GM-1. Morphology of red blood cell in GM-1 group was similar to normal diet group but the control group had many crystals of cholesterol. Hepatic xanthine oxidase activity in the rats of high cholesterol-diet was decreased up to the levels of normal diet group according to oral administration of GM. The results of the present study demonstrate that the orally injection of GM can ameliorate the status of total cholesterol and LDL-cholesterol, and repress xanthine oxidase in liver in high cholesterol-diet rats. These finding suggest that GM is expected to be an effective tea for the blood amelioration in high cholesterol-diet rats.

Cheonmabanhwa-Tang(CBT) has been used in the Oriental Medicine for many centuries as a therapeutic agent for dizziness due to Poong-Dam. This Study was designed to investigate the mechanism of Prescription on cerebral hemodynamics [regional cerebral blood flow(rCBF) and pial arterial diameter(PAD)J in cerebral ischemia rats, The results in cerebral ischemic rats were as follows: Both rCBF and PAD were significantly and stably increased by CBT (10 ㎎/㎏, i.p.) during the period of cerebral reperfusion, which contrasted with the findings of rapid and marked increase in control group. Pretreatment with indomethacin(1 ㎎/㎏, i.p.), an inhibitor of cyclooxygenase significantly but unstably increased the CBT-induced increases in PAD as well as rCBF during the period of cerebral reperfusion. Pretreatment with methylene blue(10 (.1.㎍/㎏, i.p.), an inhibitor of guanylate cyclase significantly but unstably increased the CBT-induced increases in PAD as well as rCBF during 150 minutes of cerebral reperfusion, but decreased stably the CBT-induced increases in rCBF and PAD after 180 minutes of cerebral reperfusion. In conclusion, the present authors thought that CBT caused effect on cerebral hemodynamics via mediation of cyclooxygenase.

In order to elucidate the mechanism of cytotoxic effect of oxygen radicals on cultured mouse spinal motor neurons, the neurotoxicity induced by hydrogen peroxide(H₂O₂) was evaluated by MTT assay. The neuroprotective effect of Rhizoma Gastrodiae(RG) against H₂O₂-mediated neurotoxicity was also examined in these cultures by SRB assay. The results were as follows : The value of lethal concentration 50(LC50) of H₂O₂ was estimated at a concentration of 30 uM in these cultures. Cell viability of cultured mouse spinal motor neurons was remarkably decreased by H₂O₂-induced neurotoxicity in a dose- and time-dependent manner. RG was remarkably effective in blocking the neurotoxicity induced by H₂O₂ at a concentration of 120 μM as determined by SRB assay. From above the results, it is suggested that H₂O₂ induce neurotoxicity, and the selective herbal extracted RG was very effective in blocking H₂O₂-mediated neurotoxicity on cultured mouse spinal motor neurons.

Impairment of balance between bone-resorbing osteoclasts and bone-forming osteoblasts result in bone disease. Especially, increased osteoclast formation and activity are responsible for bone diseases such as osteoporosis, rheumatoid arthritis, periodontal disease. Natural metabolites of plants have recently received much attention as an alternative tools for the development of novel therapeutic strategy. The aim of this study was to search the natural products to inhibit osteoclast differentiation and was to evaluate of its mechanism. Water extract of Gastrodia elata Blune significantly inhibited receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclast differentiation in bone marrow macrophages (BMMs) in a dose dependent manner. However, water extract of Gastrodia elata Blune did not affect cytotoxicity when compared with control. The mRNA expression of c-Fos, NFATc1, and TRAP induced by RANKL was inhibited by water extract of Gastrodia elata Blune treatment. Also, water extract of Gastrodia elata Blune inhibited the protein expression of c-Fos and NFATc1 expression in BMMs treated with RANKL. Water extract of Gastrodia elata Blune suppressed the phosphorylation of p38 induced by RANKL. In general, RANKL considerably inhibited the expression level of Id2 and MafB known as negative regulators of osteoclastogenesis, but RANKL did not inhibit Id2 and MafB expression in BMMs when it was co-treated with Gastrodia elata Blune. Taken together, these results suggest that Gastrodia elata Blune may be a useful drug in the treatment of bone-related disease.

In order to product dry goods of Gastrodiae Rhizoma with high quality, tubers were treated with various dry methods such as cutting, drying methods and steaming. In cutting than no cutting, they were shown shorter drying hours and lower drying yield. Drying hours in freeze drying was shorter than those of hot air and far-infrared ray. Total polyphenol content was higher in cutting than no cutting. According to steaming, it was increased in freeze drying but decreased rapidly in the other dry methods. Among all treatments, hot air dry treatment with cutting and no steaming had the highest total polyphenol content. Gastrodin and 4-hydroxybenzyl alcohol contents generally were similar or higher in cutting than no cutting. By steaming, gastrodin content in freeze drying was decreased but 4-hydroxybenzyl alcohol content was increased. But hot-air and infrared ray dry, they were shown opposite results. Gastrodin and 4-hydroxybenzyl alcohol contents showed opposite reaction to each other and were shown various response by dry methods.
