The ideal goal of periodontal therapy is the regeneration of periodontal tissue repair of function. Although is very difficult to attain the goal, recent advances in periodontal wound healing concepts encourage hope reaching it. Recently many efforts are concentrated on the regeneration potential of material used in traditional Korean medicine. Phlomidis Radix has been used for the treatment of blood stasis, bone fracture and osteoporosis in traditional Korean medicine. The purpose of this study is to examine effects of dichloromethane fraction Phlomidis Radix on Bone Formation in Human Fetal Osteoblasts. Human fetal osteoblastic cell line(hFOB1 1.19 ;American Type Culture Collection, Manassas, VA) were used and cells were cultured containing DMEM and dichloromethane fraction Phlomidis Radix(100 ng/ml , 1 ${\mu}$/ml, 10 ${\mu}$/ml) at 34$^{\circ}C$ with 5% $CO_2$ in 100% humidity. MTT was performed to examine the viability of the cell, and alkaline phosphatase activity was analyzed to examine the mineralization. Also bone calcification nodules were evaluated. The cellular activity of hFOB1 was increased in 100 ng/ml, 1 ${\mu}$/ml , 10 ${\mu}$/ml of dichloromethane fraction of Phlomidis Radix and especially significant increation was showed in 100 ng/ml of dichloromethane fraction of Phlomidis Radix at 6days (p <0.05). ALP level of hFOB1 was significantly increased in 100 ng/ml , 1 ${\mu}$/ml, 10 ${\mu}$/ml of dichloromethane fraction of Phlomidis Radix and especially more increation was showed in 10 ${\mu}$/ml of dichloromethane fraction of Phlomidis Radix (p <0,05). Calcification nodules of hFOB1 significantly increased in 10 ${\mu]$/ml of dichloromethane fraction of Phlomidis Radix at 21 days of incubation(p<0.05). The results indicate that dicholoromethane fraction of Phlomidis Radix has excellent effects on mineralization of hFOB1.

As a result to amplifying 12 samples of 'Sok-dan' through an random amplified polymorphic DNA (RAPD) method using eighteen DEC and URP primers, distinct band forms enabling discrimination of Phlomus umbrosa and Dipsacus asperoides were observable in the UBC 320 primer, UBC 367 primer, UBC 385 primer, UBC 414 primer, UBC 423 primer, URP 3 primer, URP 5 primer and URP 9 primer. The polymorph result amplified with a random primer was evaluated through Gelcompar II, showing a result dividable into two groups. The divided groups were the dried sample group of Dipsacus asperoides and the group of Phlomis umbrosa. In order to recognize the distinction between Dipsaci Radix types, the genetic variation of 'Sok-dan' produced domestically and imported was evaluated through RAPD, and the potential to distinguish these in forms of dried medicine was identified, presenting a method to authentification of Phlomis umbrosa and Dispacus asperoides.

The roots of Phlomis umbrosa (Turcz.) (Phlomidis Radix) have been traditionally used to treat cold, reduce swelling and staunch bleeding. Four iridoids (1 - 3 and 5) and six phenylethanoid derivatives (4, and 6 - 10) were isolated from the roots of P. umbrosa. A simple, sensitive, and reliable analytical HPLC/PDA method was developed, validated, and applied to determine 10 marker compounds in Phlomidis Radix. Furthermore, the isolates were evaluated for cytotoxic and anti-oxidant activities as well as DPPH-HPLC method. Among them, compounds 4 and 6 - 9 displayed potent anti-oxidant capacities using DPPH assay with $IC_{50}$ values of $27.7{\pm}2.4$, $10.2{\pm}1.1$, $18.0{\pm}0.8$, $19.1{\pm}0.3$, and $19.9{\pm}0.6{\mu}M$, and compounds 6, 8, and 9 displayed significant cytotoxic activity against HL-60 with $IC_{50}$ values of $35.4{\pm}3.1$, $18.6{\pm}2.0$, and $42.9{\pm}3.0{\mu}M$, respectively.

Objectives : This study aimed to review the change in the origin of Sokdan(續斷) by diachronically analyzing literature data from Korea and China. Methods : Literature records describing the origin(synonyms, location of production, description) of Sokdan were collected, records were divided into periods. The main contents were included in the results, and original texts were edited and summarized in the table. Results : Sokdan, whose leaves resemble Jeoma(苧麻)(SJ), was first recorded in 《Xinxiubencao(新修本草)》, and described in detail in 《Bencaotujing(本草圖經)》 during the Tang and Song dynasties in China. In modern times, SJ was assumed to be genus Phlomoides or Lamium; however, records of the plant have decreased. Finally, SJ was not included in the 《Pharmacopoeia of the People's Republic of China》 as Sokdan. However, 《Diannanbencao(滇南本草)》, 《Diannanbencaotushuo(滇南本草圖說)》, 《Zhiwumingshitukao(植物名實圖考)》 described Sokdan of dian(滇). It was assumed genus Dipsacus. From the 1950s onwards, Sokdan is described in the literature as a member of the genus Dipsacus. In korea, SJ was recorded in 《Hyangyakjipseongbang(鄕藥集成方)》 and 《Dongeuibogam(東醫寶鑑)》 during the Joseon dynasty. In modern times, the genera Phlomoides and Lamium were mostly recorded as the origin of Sokdan. Conclusions : Several species have been described as Sokdan over the years in China, but since the 1950s, the genus Dipsacus was noted as the origin of Sokdan. In Korea, SJ was used in the past, thus Sokdan was recorded as P. umbrosa in 《The Korean Herbal Pharmacopoeia(KHP)·1985》. However, 《KHP·1998》 referred to P. umbrosa as Hansokdan and D. asperoides as Sokdan.

The purpose of present study was to investigate the effects of physiologically active compound (SD62-122) from Phlomidis Radix on the cell cycle progression and its molecular mechanism in human gingival fibroblasts(HGFs). For this purpose, fibroblasts were isolated and cultured from excisioned gingiva during crown lengthening procedure in healthy adult. The following parameter were evaluated that there are cell number counting, MIT assay, cell cycle progression, western blot analysis. The cell number and MIT assay of primary cultured fibroblast was not increased at 2 days but significant increased compare to negative control at 3days(p<0.05). S phase was increased and G1 phase decreased in both $10^{-8}M$ and $10^{-9}M$ of SD62-122 in cell cycle analysis. The cell cycle regulation protein levels of Cyclin $D_1$, Cyclin E, cdk 2, cdk 4 and cdk 6 were increased compare to control in both $10^{-8}M$ and $10^{-9}M$ of SD62-122. The protein levels of p21 and p53 were decreased compare to control, but the level of pRb was not changed compare to control in $10^{-9}M$ of SD2-122. These results suggested that physiologically active compound (SD62-122) isolated from Phlomidis Radix increases the cell proliferation and cell cycle progression in HGFs, which is linked to increased cell cycle regulation protein levels of Cyclin $D_1$, Cyclin E, cdk 2, cdk 4 and cdk 6, and decreased the levels of p21, p53.

80% Methanol extracts of 44 traditional drugs used for the treatment of liver diseases or tonic effects were screened for anti-hepatotoxic activity by in vitro assay using $CCl_4-induced$ cytotoxicity in primary cultured rat hepatocytes. $CCl_4-induced$ cytotoxicity was evaluated by determination of LDH, GOT or GPT activity in the medium. Rehmaniae Radix Preparata and Gelantina nigra inhibited the release of LDH, GOT or GPT from $CCl_4-treated$ hepatocytes. Gibotii Rhizoma and Eucommiae Cortex showed inhibitory effect on release of LDH from normal hepatocytes as well as $CCl_4-treated$ hepatocytes. Eucommiae Cortex and Lili Bulbus decreased release of GOT and LDH from normal hepatocytes, respectively. Astragali Radix inhibited release of GPT in $CCl_4-treated$ hepatocytes. Phlomidis Radix, Imperatae Rhizoma, Cistanchis Herba, Broussonetiae Fructus, Asparagi Tuber, Trigonellae Semen and Polgonati Rhizoma inhibited release of LDH from $CCl_4-treated$ hepatocytes. Among 44 traditional drugs, most of them released LDH, GOT or GPT at the dose of 1 mg/ml in normal hepatocytes, and Drynariae Rhizoma, Acanthopanacis Cortex, Longanae Arillus, Atratylodis Rhizoma and Ecliptae Herba increased $CCl_4-induced$ cytotoxicity.

Dipsaci Radix (Dipsacaceae) has been used as a tonic, an analgesic, anti-inflammatory and anti-complement agents in traditional herbal medicine for the therapy of low back pain, knee pain, rheumatic arthritis, traumatic hematoma, and bone fractures. A high-performance liquid chromatography-electrospray ionization-mass spectrometric method (HPLC-ESI-MS) was developed for the simultaneous quantitation method of the five compounds from the herbal drug: asperosaponin VI and asperosaponin XII (terpene glycosides), sweroside, loganin and dipsacus A(iridoid glycosides). HPLC separation of the analytes was achieved on a C18 column ($150{\times}2.0$ mm i.d., 5 ${\mu}m$) using the aqueous methanol containing 5 mM ammonium acetate with gradient flow of the mobile phase. Detection of the analytes was performed by positive ion electrospray ionization, and selected ion monitoring was used for data acquisition using m/z corresponding molecular adduct ion, $[M+NH_4]^+$ and $[M+H]^+$. Calibration graphs showed good linearity ($r^2$=0.9997) over the wide range of the analytes; intra- and inter-day precisions (RSD, %) were within 9.1% and the accuracy between 94.0-111.0%. Recoveries of the analytes through the assay procedure were in the range of 93.7-110.8%. Analytical results of the herbal drugs of Dipsaci Radix (17 samples) show wide distribution of the five marker compounds and clear difference of the species from Phlomidis Radix (4 samples). The developed method would provide a practical guide for the quality control of the herbal drug.
