The rate of growth and production of bioactive substances from Rehmannia glutinosa Liboschitz (Scrophulariaceae) were studied with the variation on the constituents of the culture media. The best growth was observed from MS basal medium containing 3.0 ppm NAA and 2.0 ppm kinetin. Carbohydrates (fructose, glucose and sucrose), phytosterols(${\beta}-sitosterol$, campesterol and stigmasterol) and carotenoid like substances were identified by GC-MS and TLC from the callus mass. However, catalpol was not detected from both solid and cell suspension cultures containing geraniol. Callus cultured Rehmannia glutinosa in the MS basal medium containing 0.1 ppm NAA and 0.1 ppm kinetin become differentiated to root.

Objectives : The aim of this study was to investigate the effects of Ginseng Radix (Panax ginseng C.A. MEY.), Zizyphi Spinosae Semen (Zizyphus spinosa HU.) and Rehmanniae Radix Preparat (Rehmannia glutinosa LIBOSCH.) on the serotonin- immunoreactivity cells in the Caudal raphe nuclei, Rostal raphe nuclei and hippocampus of the mouse brain. Methods : The mice were stressed by restraining for one hour and treated with herbal medicine by oral feeding. The mice were killed after one hour and observed by electron microscope after immunohistochemical staining. Results : In the caudal raphe nuclei of the medulla oblongata, the highest number of 5-HT immunoreactivity cells were observed at the Zizyphi Spinosae Semen-treated group, while the lowest level among the herbs treatment group was shown at the Ginseng Radix group. In the hippocampus, serotonin-immunoreactive cells were expressed significantly at the CA3 area while the lowest level of it was shown at the control group. In the midbrain, immunoreactive cells were expressed higher than other groups, while observed at the lowest level in the control group. Conclusions : The extracts of Zizyphi Spinosae Semen, Rehmanniae Radix Preparat and Ginseng Radix show a certain degree of effect on the change of serotonin immunoreactive neurons as an index of nerve disorder.

Objectives: Pulse energy values recorded with an add-pres sure-type pulse apparatus were correlated with Sasang constitutional syndromes in order to match pulse energy values with Sasang prescriptions. Methods: The pulse energy values were measured with Daeyo Pulse Apparatus at the Gwan pulse point of both wrists. Prescriptions were divided into two major categories of interior syndromes or exterior syndromes, and categorized according to major component herbs specific to each of the four Sasang constitutions, and the relationship between the pulse energy and each groups divided by their prescription was studied. Results: About 10% of all people had nonmal pulse energy values. 10% had values over normal range, and $70\sim80%$ had lower values than normal. The normal range of pulse energy was regarded as being between 450 and 700. Conclusions: 1. For patients of the Soeum constitution, prescriptions without Panax ginseng is suitable for patients with high pulse energy, and prescriptions containing Panax ginseng are suitable for patients who have lower pulse energy. 2. All prescriptions for the Soyang constitution containing Rehmannia radix preparata or Comus officinalis are suitable for patients who have lower pulse energy, and prescriptions containing Rehmannia radix or Gypsum fibrosum are applicable to patients with pulse energy values higher than normal. 3. Most prescriptions for the Taeum constitution containing Semen coicis or Semen castaneae are suitable for patients with lower pulse energy, and prescriptions containing Radix puerariae or Radix et rhizoma rhei can be prescribed for patients who have lower pulse energy levels. 4. The Taeyang constitutional prescription Ogapijangcuck-tang is suitable for patients who have higher pulse energy levels and Mihudeungsikjang-tang is better for patients with lower than normal pulse values. As described above, the pulse energy level of each patient can be matched with a specific Sasang constitutional prescription. If this relationship is taken into consideration with other conventional symptoms, it can be helpful in diagnosis, improving efficacy of treatment, and be used as objective evidence.

This study is carried out to evaluate the genotoxicity of herbs (Angelica decursiva, Polypori umbellate, Astragalus membranaceua, Paeonia iactiflora, Glycyrrhiza uralensis, Cnidium officinale, Rehmannia glutinosa, Cyperus rotundus, Dioscorea batatas and Platycodi Radix) by using the Ames test. The Salmonella typhimurium reversion assay is being performed by using the Sal. typhimurium TA98, TA100, TA102, TA1535 and TA1537 as tester strains. Among 70% of ethanol extracts from 10 herbs, the number of revertant colonies is being increased in Astragalus membranaceua, Cnidium officinale and Dioscorea batatas in a dose-dependent manner, as compared with negative controls of the metabolic activation. In case of dichloromethane and ethyl acetate fraction from 70% of ethanol extracts, the number of revertant colonies is increased in Angelica decursiva, Astragalus membranaceua, Cnidium officinale, Rehmannia glutinosa and Dioscorea batatas in a dose-dependent manner, as compared with negative controls of metabolic activation. Such results indicate that Angelica decursiva, Astragalus membranaceua, Cnidium officinale, Rehmannia glutinosa and Dioscorea batatas all show genotoxic effects when being extracted with the solvent extractions such as 70% of ethanol, dichloromethane and ethyl acetate, and thus, they might be genotoxically- non-safe.

To improve the quality control of frequently used oriental medicinal plants, the storage, cutting, processing and decokting methods of Rehmannia glutinosa Libosch. var. purpurea Makino(熟地黃) were examined. The contents of 5-hydroxymethyl-2- furaldehyde(5-HMF) of Rehmannia glutinosa Libosch. var. purpurea Makino were analysed by HPLC at various conditions as the standard component. Raw materials were classified into 3 groups with their specific gravity(天 地 人黃) and determined the ding weights and the contents of water, the solid component of Ji-Hwang(地黃) was the most. Rehmannia glutinosa Libosch. var purpurea Makino was steamed and dried nine times and analysed the content of 5-HMF on every time. In the case of Ji-Hwang, the standard component of the ninth sample was produced the most. But which of the tenth samples of Chun-Hwang and Yin-Hwang(天黃 人黃) were the most. The best decokting conditions which were determined by the yield of 5-HMF were as follows : non cutting, soaking time was 0 minutes, decokting time was 75 minutes after boiling. The contents of sugar on each of samples were determined. The contents of standard component increased by steaming number and the contents of sugar decreased.

The steamed root of Rehmannia glutinosa has been used for treatment of inner ear diseases, such as tinnitus and hearing loss in traditional Oriental Medicine. In the present study, we investigated the effect of ethanol extract of steamed root R. glutinosa (SRG) on cisplatin cytotoxicity of HEI-OC1 auditory cells. In addition, to investigate the mechanism of SRG on cisplatin cytotoxicity, the effects of SRG on lipid peroxidation as well as scavenging activities against various free radicals were measured in cisplatin-treated cells. Treatment of SRG protected cells from cisplatin and reduced lipid peroxidation in a dose-dependent manner. Furthermore, SRG demonstrated significant scavenging activity against various free radicals, including superoxide radical, hydroxyl radical, hydrogen peroxide, and DPPH radical. These results indicate that SRG protects cisplatin-induced damages of HEI-OC1 cells through inhibition of lipid peroxidation and augmenting scavenging activities against free radials.

Rehmannia Radix Preparata (RRP) used to nourish Eum and enrich blood for consumptive fever, aching, and limpness of the loins and knees, and to replenish essence for tinnitus, premature greying of beard and hair. In the present study, we studied about the protective effect of RRP on hydrogen peroxide-induced oxidative stress in human vascular endothelial cells. ECV304 cells were preincubated with RRP (100, 200, 300 and $400{\mu}g/m{\ell}$) for 12hr and then treated with $600{\mu}M$ $H_2O_2$ for 12hr. The protective effects of RRP on $H_2O_2$-induced apoptosis in ECV304 cells was determined by using MTT assay, FDA-PI staining, flow cytometric analysis, caspase-3 activity assay, ROS assay and western blot. The results of this experiment showed that RRP inhibited $H_2O_2$-induced apoptosis and ROS production in ECV304 cells. Moreover, RRP increased ERK activation that decreased in $H_2O_2$-treated ECV304 cells, and inhibited p38 and JNK activation. Furthermore, RRP increased expression of heme oxygenase-1 (HO-1) in $H_2O_2$-treated ECV304 cells. Also, HO-1 protein expression induced by RRP was reduced by the addition of ERK inhibitor (PD98059) in $H_2O_2$-treated ECV304 cells. These results suggest that protective effect of RRP on $H_2O_2$-induced oxidative stress in ECV304 cells may be associated with increase of ERK activation and HO-1 protein, and reduction of p38 and JNK activation.
