Adventitious shoots were directly induced from leaf explants of R. glutinosa, an important medicinal plant. Proliferating shoot cultures were obtained by culturing leaf discs on Murashige and Skoog(MS) medium alone or combination with auxins and cytokinins. MS medium supplemented with 1 $mg/{\ell}\;BA\;and\;2\;mg/{\ell}$ IAA was the most effective, providing high shoot bud formation frequency without formation of intervening callus. The effect of leaf age on adventitious shoot formation was also investigated. The maximum shoot bud production (93.4%) was achived using 3rd leaf from apex of 6 weeks old plantlets after seed germination. Plantlet were rooted on an half-strength MS (1/2MS) medium containing 0.1 $mg/{\ell}\;IBA$. This prtocol is useful for clonal propagation and Agrobacterium-mediated transforamtion in R. glutinosa.

The aim of this article is to investigate the religious medical treatments performed by Kang Jeungsan as recorded in The Canonical Scripture, the main scripture of the Korean new religion, Daesoon Jinrihoe. The unity of mind and body is the core principle underlying Kang Jeungsan's religious medical treatments. He believed treating the mind of his patients was more important and necessary than treating their diseases. As such, he believed the only way to treat critical illness was to keep preserve the mind-body unity of his patients. Massage was a physical therapy often used by Kang Jeungsan. The medicinal materials that he commonly used were the Four-substance Decoction (四物湯 samultang), Minor Bupleurum Decoction (小柴胡湯 soshihotang), quince (木瓜 mokgwa *Pseudocydonia sinensis; not papaya), and rehmannia (生地黃 saengjihwang). Kang Jeungsan's religious medical treatments were characteristic of Daoist healing methods. His Daoist style healing methods included multiple techniques such as treating diseases through correcting Qi, exorcising malevolent entities, transferring diseases to a different host, removing a disease through the changing of clothes, pouring medicine into the ground, combining the usage of talisman and incantations, and treating the common people. Among these techniques, Jeungsan's pouring medicine into the ground was especially innovative.

Objectives The purpose of this study is to review relevant clinical studies to investigate the effectiveness of herbal medicines for IgA (Immunoglobulin A) nephropathy in children. Methods Studies on herbal treatment for IgA nephropathy were searched and analyzed through electronic databases such as PubMed, EMBASE, China National Knowledge Infrastructure, Wanfang, CiNii, J-STAGE, Oriental Medicine Advanced Searching Integrated System and Science ON. Studies included Randomized controlled trials and case series. Results We selected nine studies and analyzed the findings. In most studies, improvement of IgA nephropathy was observed after treatment, and was evaluated using factors as 24 hour urine protein, hematuria, Scr (serum creatinine) and BUN (blood urea nitrogen). The most commonly used herbs for IgA nephropathy were Poria cocos (茯苓), Astragalus membranaceus (黃芪), and Rehmannia glutinosa (生地黃). Conclusions Based on the results of the clinical studies, we identified that herbal medicine is an effective treatment for IgA nephropathy. However, additional systematic clinical studies are necessary to prove its effect and safety.

Background: Rehmanniae radix preparata (RRP) has been used as a traditional medicine and is one of the most important oriental herbal medicines. However, the physical characteristics of RRP are not suitable for use in industry. The present study was under-taken to determined the preparation method of RRP powder and the physicochemical characteristics of RRP powder by milling under different pre-freezing temperatures. Methods and Results: Moisture content, powder yield, particle size, bulk density, compressive stress, extraction yield, and 5-HMF content of PRR powders by milling with pre-freezing temperatures (-20, -40, -60, and $-80^{\circ}C$) were analyzed, and correlation among these factors was determined. Powder yield increased and particle size decreased in a pre-freezing temperature-dependent manner from -20 to $-60^{\circ}C$. The Hausner ratio increased from 1.186 to 1.225 with decreasing temperature from -20 to $-80^{\circ}C$, whereas compressive stress showed the opposite trend. Extraction yield and 5-HMF content were not significantly different between RRP powder. Significant correlations were observed among pre-freezing temperature and physical characteristics (e.g., yield, particle size, Hausner ratio, and compressive stress). Conclusions: These results suggest that the pre-freezing temperature is an important factor affecting the physical characteristics of PRR powder and applicable to the industrial production of RRP powder.

Samultang is one of traditional medicine composed of Paeonia lactiflora, Angelica gigas, Rehmannia glutinosa and Cnidium officinale. To develop simultaneous determination of paeoniflorin, decursin and 5-HMF in Samultang, a high performance liquid chromatography with diode array detector was used. To separate three marker components, Dionex $C_{18}$ column (5 ${\mu}m$, 120 ${\AA}$, 4.6 mm${\times}$150 mm) was used with a gradient elution system of water and methanol. UV wavelength of detector set at 230 nm and 280 nm. This method was validated by linearity, precision test and recovery test. Calibration curves of three standard components were showed good linear regression ($R^2$>0.9973). LOD and LOQ ranged from 0.08 ${\mu}g$/ml to 0.38 ${\mu}g$/ml and 0.25 ${\mu}g$/ml to 1.16 ${\mu}g$/ml, respectively. The relative standard deviations (RSDs) of data of the inter-day and intra-day experiments were less than 0.54% and 0.89%, respectively. The measured results of recovery test were varied from 93.36 to 107.79 with RSD values 0.01~1.45%. The established method was applied for separation of bio-conversion Samultang sample and compared with control sample.

Sopungchungyoung-tang (SCT) has been widely used in Korea as a treatment of atopic dermatitis. SCT consists of Talcum, Rehmannia glutinosa, Angelica sinensis, Paeonia lactiflora, Cnidium officinale, Ledebouriella divaricata, Schizonepeta tenuifolia, Scutellaria baicalensis, Glycyrrhiza uralensis, Mentha arvensis, Cordyceps cicadae. We examined the immunological effect of SCT in vitro. We studied about the effect of SCT on Th cells' differentiation. In the case of CD4 T cells under neutral condition where there was only rIL-2 stimulus, SCT inhibited IFN-γ secretion by 70-80 %. Likewise, SCT also inhibited the IL-4 secretion of neutral Th cells by 85-90 %. We also experimented with the polarized Th1 cells/ Th2 cells and their production of IFN-γ and IL-4, respectively. There also were inhibitory effects on the polarized cells like there was on neutral cells, they were not as strong on the polarized cells. Under Th1 polarized condition, SCT acted dose-dependently, while in Th2 cells, the IL-4 production was inversely proportional to the doses of SCT. From the current study, it can be concluded that SCT exerts inhibitory effects on cytokine production without interfering with immune cells' activity. The result that SCT inhibits IFN-γ and IL-4 confirms that it does have a effect on immunomodulation.

Anti-inflammatory factor(AIF) is a water soluble extract of three herbs, Panax notoginseng(Burk.) F. H. Chen, Rehmannia glutinosa Libosch and Eleutherococcus senticosus. The present study aimed to investigate the safety and efficacy of herb extracts, AIF, on Korean knee osteoarthritis patients for six weeks. Fifty seven patients with knee osteoarthritis, ranging from 43 to 73 years of age, who fulfilled the "American College of Rheumatology"(ACR) classification of idiopathic osteoarthritis of knee and radiographic criteria were randomly selected and enrolled for the study. After initial screening and resting period, two capsules each of AIF(Each capsule contains; 400 mg) and similar identical placebo were administered twice a day to both groups. Pain intensity at second, fourth, and sixth weeks of study as well as one week after discontinuation of drugs was assessed by using 100 mm visual analogue scale(VAS). Changes in the Korean version of the Western Ontario and McMaster Universities(K-WOMAC) index score were compared at the initiation and completion of the study. VAS assessed by patients were significantly reduced(at visit 2; $54.64{\pm}14.72$, at visit 4, $37.32{\pm}16.58$, p<0.001) after AIF administration. Results showed an improvement in the physical function of K-WOMAC scale which was significantly higher(p=0.013) in AIF than placebo group, and decreases of total K-WOMAC score were also significantly higher(p=0.030) in AIF groups than placebo group. No serious adverse effect was observed, and there was no difference in incidence of adverse effect between AIF and placebo groups. In this population of Korean patients with knee osteoarthritis, AIF was found to be safe, tolerable and effective for symptomatic improvement of pain and physical function.

There was no significant difference in length and width of leaf and number of leaves per plant between tissue-cultured plants and conventionally propagated ones but chlorophyll content increased in tissue-cultured ones. Percent of sprouting from planted root segments significantly increased in tissue-cultured plants, resulting in yield increase of more than 200% per 10a. Root thickness of tissue-cultured plants at the time of planting influenced percent of sprouting and yield. Plants with root diameter ranging from 3 to 6mm gave good yield. When virus infection was monitored with N. tabacum and C. amaranticolor as indicator plants, 100% infection occurred in vegetatively propagated plants and introduced plants from China. whereas plants obtained from apical meristem showed 0% and 40% to 45% infection in vitro plantlets and 1 year old plants in vivo, respectively. Tobamovirus and unidentified virus particles were detected in electron microscopy.
