항암제로 알려진 cisplatin과 t-BHP를 토끼에 투여하여 유도된 급성 신부전 시 산조인 추출액을 처리하였을 때 신장 세포의 보호에 미치는 항산화 효과를 조사하였다. 신장을 분리한 후 신피질 절편 실험에서 세포의 손상을 유발하는 지질과산화 및 LDH 실험에서 t-BHP 단독 처리 시 대조군에 비하여 각각 3배, 5배 이상 증가하였으나 산조인 추출액 0.5%를 동시 처리하였을 때는 대조군 수준으로 감소하였다. Creatinine 측정과 지질과산화 실험에서 cisplatin $5mg{\cdot}kg^{-1}$을 복강 투여한 군의 creatinine 농도가 $2.13{\pm}0.1mg{\cdot}dl^{-1}$로 나타났으나 산조인 추출액 $50mg{\cdot}kg^{-1}{\cdot}day^{-1}$을 7일간 전처리 후 cisplatin 투여 48시간 경과한 군은 $0.84{\pm}0.1mg{\cdot}dl^{-1}$로 creatinine의 농도가 약 60% 감소되는 신장보호 효과를 나타내었고, 지질과산화 검사는 cisplatin 단독 투여 시 대조군에 비하여 1.6배 높게 나타났으나 산조인 추출액 전처리 시 1.1배로 대조군과 유사하였다. 병리조직 검사는 cisplatin 단독 처리군에서 근위곱슬세관이 대조군에 대하여 더 붉게 염색되었으며 근위곱슬세관은 내강의 융모세포가 탈락하여 공포를 형성하였다. 그러나 산조인 추출액을 7일간 전처리한 군에서는 근위곱슬세관이 대조군과 유사한 염색소견을 보였고 근위곱습세관도 내강의 융모세포 탈락이 거의 나타나지 않았다. 따라서 cisplatin과 t-BHP에 의해 유발된 신장세포 손상에 대하여 산조인 추출액이 항산화 효과를 보였다.

Pyungwi-san has been used to treat the digestive system diseases, physconia, nausea, anorexia, and dyspepsia in Korea. In this study, an ultra-performance liquid chromatography-electrospray ionization-mass spectrometry (UPLC-ESI-MS/MS) method was optimized for simultaneous determination of the 14 marker components, spinosin, liquiritirn apioside, liquiritin, narirutin, 6'''-feruloylspinosin, hesperidin, liquiritigenin, glycyrrhizin, 6-gingerol, atractylenolide III, honokiol, atractylenolide II, magnolol, and atractylenolide I in Pyungwi-san extract. All analytes were separated on a Waters Acquity UPLC BEH $C_{18}$ analytical column ($2.1{\times}100mm$, $1.7{\mu}m$) with maintained at $45^{\circ}C$. The mobile phase consisted of 0.1% (v/v) aqueous formic acid and acetonitrile. The MS conditions were as follows: capillary voltage 3.3 kV, extractor voltage 3.0 V, RF lens voltage 0.3 V, source temperature $120^{\circ}C$, desolvation temperature $300^{\circ}C$, desolvation gas 600 L/h, cone gas 50 L/h and collision gas 0.14 mL/min. The coefficient of determination of 14 analytes was 0.9989-1.0000. The limits of detection and quantification values of the all analytes were 0.04-2.56 and 0.13-7.69 ng/mL, respectively. As a result of the analysis using the established LC-ESI-MS/MS method, the 5 components, spinosin, 6'''-feruloylspinosin, atractylenolide III, II, and I derived from Zizyphi Fructus and Atractylodis Rhizoma, were not detected in this extract. On the other hand, the 9 components except for the 5 components were 4.15-498.87 mg/kg in lyophilized Pyungwi-san extract. Among these components, glycyrrhizin, marker compound of Glycyrrhizae Radix et Rhizoma, was detected the most amount as a 498.87 mg/kg.

SosokMyeongTang(SMT) have been used in oriental medicine for many centuries as a therapeutic agent for cerebral disease. The effects of SMT on the vascular system is not known. The purpose of this study was to investigate the effects of SMT on the changes in blood pressure(BP) and regional cerebral blood flow(rCBF) of rats. SMT consists of the following components : Radix Ledebouriellae(防風), Radix Cocculi or Stephaniae(防己), Semen Armeniacae(杏仁), Cortex Cinnamomi(肉桂), Radix Scutellariae(黃芩), Radix Paeoniae Lactiflorae(白芍藥), Radix Ginseng(人蔘), Rhizoma Cnidll(川芎), Herba Ephedrae(麻黃), Radix Glycyrrhizae(甘草), Radix Aconiti(附子?), Fructus Zizyphi Jujubae(大棗), Rhizoma Zingiberis(生薑) and the changes of BP and rCBF were tested Leser-Doppler Flowmetry(LDF) The experimental results were as follows ; BP was not affected by SMT in rats, but rCBF was increased significantly by SMT in a dose dependent manner. SMT increased previous decreasd rCBF due to pretreatment methylene blue, but did not increased previous decreasd rCBF due to pretreatment L-NNA, indomethacin. Pretreatment with indomethacin decreased BP compaired with control group. These results suggest that SMT causes a diverse response of blood pressure and regional cerebral blood flow(rCBF). The increased rCBF is mediated by nitric oxide synthease.

Bulhwangeumjeonggisan (BHGJGS) is a traditional herbal formulation generally used in the treatment of cold and gastritis. BHGJGS consists of eight herbal plants; Atractylodis Rhizoma, Magnoliae Cortex, Citri Pericarpium, Glycyrrhizae Radix, Agastachis Herba, Pinelliae Rhizoma, Zingiberis Rhizoma and Zizyphi Fructus. Complete standardization of this formulation has not been done yet. So, a simple and accurate method was developed and validated using Ultra Performance Liquid Chromatography (UPLC) with Diode Array Detector (DAD) for the standardization of BHGJGS. UPLC conditions were optimized using a c18 RP-Amide column with mobile phase; 0.1% phosphate buffer and acetonitrile, detection wavelength; 210 and 325 nm. The linearities of calibration curves were acceptable ($R^2$>0.9994), and the limit of detection and quantification were within the ranges of 0.011-0.091 and $0.034-0.277{\mu}g/ml$ respectively. The relative standard deviation (RSD) of intra- and inter-day precisions were under 3.61%. The RSD of repeatability was under 0.68 %. The results of recovery test were 94.4-107.9%, and the RSD were under 4.6%. The developed method was used to find the contents of standard constituents in BHGJGS mix extract powder, and two commercial formulation (A and B). The data show that the developed method was specific, sensitive, accurate, and precise for analysis of BHGJGS components.

Interieukin 1${\beta}$ is a potent bone resorptive cytokine which mediates soft tissue destruction through the stimulatidn of prostaglandin production and the induction of collagenase. This constellation of activities suggests a role of IL-1${\beta}$ in the pathogenesis of periodontal disease. The purpose of this study was to evaluate the effects of herbal extracts on production and activity of IL-1${\beta}$. When LPS was added to cultured human blood monocytes, the effects of herbal extracts on the production of IL-1${\beta}$ was evaluate by thymocyte stimulation assay. When rHuIL-1${\beta}$ was added to cultured human gingival fibroblasts, the effects of herbal extracts on production of $PGE_2$ was evaluated by ELISA and when it was added to cultured mouse calvaria, the effects on bone resorption was estimated by .$^{45}Ca$-release bone resorption assay. The herbal extracts that had been used in this study were as follows; Asparagi Radix, Schzandrae Fractus, Zizyphi Fractus and Rhois Galla. The following results were obtained from this study. 1. All these extracts effectively inhibited the production of IL-1${\beta}$ on cultured human blood monocytes. 2. All these extracts effectively inibited the production of $PGE_2$ on cultured human gingival fibroblasts. 3. All these extracts did not effectively inhibit the bone resorption induced by rHulL-1${\beta}$ on cultured mouse calvaria.

The effects of the oriental herbal medicine Saenghyetang(SHT, 生慧湯), which consists of Rehmanniae Radix (熟地黃 九蒸: was made by 9th steam) 40g, Corni Fructus(山茱黃) 16g, Polygalae Radix(遠志) 8g, Zizyphi Spinosae Semen(酸棗仁) 2g, Biotae Semen(柏子仁 去油: oil ingredient was removed) 20g, Poria Cocos(茯笭) 12g, Ginseng Radix(人蔘) 12g, Acori Graminei Rhizoma(石菖蒲) 2g, Sinapis Semen(白芥子) 8g, on learning ability and memory were investigated. Hot water extract(HWE) and ethanol extract(EE) from SHT were used for the studies. Learning ability and memory are related to modifications of synaptic strength among neurons that interactive. Enhanced synaptic coincidence detection leads to improved learning ability and memory. If the NMDA receptor, a synaptic coincidence detector, acts as a graded switch for memory formations, enhanced signal detection by NMDA receptors should enhance learning ability and memory. It was shown that NR2B was increased in the forebrains of oriental medicine-administrated mice, leading to enhanced activation of NMDA receptors and facilitating synaptic potentiation in response to stimulation at 10-100 Hz. These HWE-SHT treated mice exhibited that superior ability in learning and memory when performing various behavioral tasks, showing that NR2B is enhanced by HWE-SHT treatment and also is critical in gating the age-dependent threshold for plasticity and memory formation. NMDA receptor-dependent modifications, which were mediated in part by HWE administration, of synaptic efficacy, therefore, represent a mechanism for associative learning ability and memory. Results suggest that oriental medical enhancement of NR2B contributes to increase intelligence and memory in mammals On the other hand, to examine the effects of EE-SHT on the learning ability and memory in experimental mice, EE-SHT was tested on passive and active avoidance responses. The EE-SHT ameliorated the memory retrieval deficit induced by ethanol in mice, but not other memory impairments. EE-SHT(10, 20mg/100 g, p.o.) did not affect the passive avoidance responses of normal mice in the step through and step down tests, the conditioned and unconditioned avoidance responses of normal mice in the shuttle box, lever press performance tests and the ambulatory activity of normal mice in a normal condition. However, EE-SHT at 20 mg/kg significantly decrease the spontaneous motor activity during the shuttle box test, and also to extend the sleeping time induced by pentobarbital in mice. These results suggest that SHT has an ameliorating effect on memory retrieval impairments and a weak tranquilizing action.
