Objectives : In Alzheimer's disease(AD), free radical oxidative stress caused by amyloid beta-peptide may lead to DNA damage, neuronal dysfunction, neurotoxicity and cell death, Hwangryunhaedok-tang(HHT) is traditionally used for the treatment of pyrogenetic diseases. To develop a new anti-AD drug from natural herb, HHT was selected and extracted in this study. Methods : The antioxidant activities of HHT water extract powder were examined by hydroxyl radical-induced DNA strand nicking assay, and antioxidative enzymes expression assay in H4IIE cell. In addition, HHT was examined for the inhibitory effect on the acetylcholinesterase(AChE) using by Ellman's coupled assay. Results: The HHT exhibit DNA protective effect in the hydroxyl radical-induced DNA Strand nicking assay, mRNA expression of superoxide dismutase and glutathione peroxidase were recovered at a normal level by HHT treatment in H4IIE cell. Furthermore, water extract of HHT showed inhibitory effect on AChE activity. Conclusion : These results suggest that HHT may be effective in delaying and preventing AD progression related to the free radical-induced DNA damage and AChE activity.

This study was performed to investigate the effectiveness of Hangryunhaedocktang (HHT) on epidermal damages induced by allergic contact dermatitis (ACD). The sensitization were caused by one application of $25{\mu}l$ of 5% 2,4-dinitroch1orobenzene (DNCB) onto a back-lumbar skin of BALB/c mice. 2 weeks later, ACD was elicitated with $4{\mu}l$ of 2.5% DNCB and then mice were given HHT extract in doses of 3.3ml/kg/day, for 72 hours. The ACD induced epidermal damages in HHT treated ACD mice was more mitigated than non-treated ACD elicited mice. The features related with epidermal damage such as epidermal hyperplasia, infiltration of inflammatory cells, increase of nuclear shrinkages and vacuolation, and enlargement of intercellular space softened. And the distribution of soybean agglutinin (SBA) positive reaction in stratum spinosum (SS) and stratum basale (SB) were similarly maintained in a normal configuration. The numerical decrease of BrdU, TUNEL, and Fas positive cells observed were prominent in SB. Results suggest a benefit role for HHT in mitigating epidermal damages in mice with allergic contact dermatitis.

Objective : This study was designed to asses the effect of Hwangryunhaedoktang and herbs on Mouse neuroblastoma 2a cells damaged by hypoxia-reoxygenation. Method : Mouse neuroblastoma 2a (N2a) cells were measured by MTT assay and LDH assay after 48h hypoxia and 6h reoxygenation. Mouse neuroblastoma 2a (N2a) cells were treated by Hwangryunhaedoktang and herbs. Result : 1. Hwangryunhaedoktang was effective on LDH assay of hypoxia and reoxygenation. 2. All of herbs were generally effective on LDH assay of hypoxia and reoxygenation. In LDH assay of hypoxia, the effects of herbs depended on concentration. In MTT assay of hypoxia, Coptidis Rhizoma and Gardeniae Fructus were effective. In MTT assay of reoxygenation most of herbs were not effective. But Phellodendri Cortex was effective in high concentration. Conclusion : The results imply that Hwangryunhaedoktang and all herbs of it nay have protective effect on dementia and aging.

In order to investigate the effect of 'Whangryonhaedok-Tang' on the anti-inflammatory, ileum of mice, blood pressure, blood glucose, total cholesterol and antibacterial activity, those pharmacological actions were conducted. The results of this studies were summarized as follows; Rat hind paw edema induced by acetic acid was inhibited. In mice, tone of intestinal smooth muscle was suppressed with the treatment of sample and intestinal contractions induced by $BaCl_2$ was inhibited. Hypertensive effect was not observed in rabbits but was observed by the water extract of 'Whangryonhaedok-Tang' excluded Phellodendri Cortex in rabbits. The increased blood glucose levels in alloxandiabetic rabbits were significantly decreased by the oral administration of the sample I after 6 days. The total cholesterol levels in alloxan-induced rabbits were significantly decreased by the oral administration of the sample I after 9 days. Antibacterial activity was observed. In addition, we thought the pharmacological actions were significantly noted by the sample III (Methanol soluble fraction) because of the purification of effective components.

The purpose of the study was to confirm what effect HRHDT treatment had on cell extinction by damage of endoplasmic reticulum induced to PC-12 cell damage by glucose deprivation. The study confirmed what effect it had on forming the condition of glucose deprivation within a culture fluid of PC-12 cell and on a nerve cell's survival rates and tested whether HRHDT could prevent extinction of PC-12 cell by glucose deprivation. Also, the study confirmed what effect HRHDT treatment had on the emitted quantity of LDH by glucose deprivation. To examine PC-12 cell's behavioral change under the condition of glucose deprivation and a protective effect of HRHDT on the change, the study observed PC-12 cell's behavioral change with a microscope. Also, the study confirmed density of calcium ion within cells followed by a culture time in the condition of glucose deprivation with FACS and confirmed what effect HRHDT treatment had on the above density of calcium ion within cells. Finally, the study carried out the western blot and confirmed what effect HRHDT treatment had on revelation of GRP 78 and CHOP protein and a segmental type of aspase 12. In this study, HRHDT rescued PC-12 cells from glucose deprivation-induced cell death. HRHDT also prevents the LDH release, Ca++ accumulation, and morphological change, which was associated with the ER stress. Furthermore, HRHDT reduced the expression of ER chaperone (Grp78 and CHOP) proteins by glucose deprivation in PC-12 cells. These results suggest that HRHDT might provide a useful therapeutic strategy in treatment of the neurodegenerative diseases caused by glucose deprivation injuries.

The present study examined the effects of water extract of Hwangruynhaedoktang plus Yukmijihwangtang add Chogudeung (HYC) on the blood pressure and renal function in spontaneously hypertensive rats (SHR). The HYC water extract blocked increase of systolic blood pressure (SBP) in SHR. The urinary volume (UV), sodium (UNaV), potassium (UkV), and chloride (UclV) excretions were significantly increased in SHR administered with high dose of water extract of HYC, but urinary osmolality was not changed. The creatinine clearance (Ccr), which is index of glomerular filtration rate (GFR), was increased by administration of HYC, while solute-free water reabsorption (TcH2O) was not changed. Taken together, these results suggest that the depressor effects of HYC, at least in part, caused by diuretic effect due to increase of glomerular filtration rate.
