Previous work demonstrated that an ethanol extract (HS0608) of a mixture of three medicinal plants of Curcuma longae radix, Phellinus linteus, and Scutellariae radix markedly inhibits $A{\beta}$ (25-35)-induced neurotoxicity. The present study was performed to further verify the neuroprotective effect of HS0608 on oxidative and ischemic cerebral injury using cultured rat cortical neurons and rats. Exposure of cultured cortical neurons to $100\;{\mu}M$ hydrogen peroxide ($H_2O_2$) induced neuronal apoptotic death. At $10-100{\mu}g/ml$, HS0608 inhibited neuronal death, elevation of intracellular calcium concentration ($[Ca^{2+}]_i$), and generation of reactive oxygen species (ROS) induced by $H_2O_2$ in primary cultures of rat cortical neurons. In vivo, HS0608 prevented cerebral ischemic injury induced by 2-h middle cerebral artery occlusion (MCAO) and 24-h reperfusion. The ischemic infarct and edema were significantly reduced in rats that received HS0608 (200 mg/kg). These results suggest that the anti-oxidative properties of HS0608 may be responsible for its neuroprotective effect against focal cerebral ischemic injury and that HS0608 may have a therapeutic role in neurodegenerative diseases such as stroke.

The present study investigated an ethanol extract (HS0608) of a mixture of three medicinal plants of Curcuma longae radix, Phellinus linteus, and Scutellariae radix for possible neuroprotective effects on neurotoxicity induced by amyloid $\beta$ protein ($A{\beta}$) (25-35) in cultured rat cortical neurons and antidementia activity in mice. Exposure of cultured cortical neurons to $10\;{\mu}M$ $A{\beta}$ (25-35) for 36 h induced neuronal apoptotic death. At $1-50\;{\mu}g/m{\ell}$, HS0608 inhibited neuronal death, elevation of intracellular calcium concentration ($[Ca^{2+}]_i$), and generation of reactive oxygen species (ROS) induced by $A{\beta}$ (25-35) in primary cultures of rat cortical neurons. Memory loss induced by intracerebroventricular injection of ICR mice with 15 nmol $A{\beta}$ (25-35) was inhibited by chronic treatment with HS0608 (25, 50 and 100 mg/kg, p.o. for 7 days) as measured by a passive avoidance test. From these results, we suggest that the antidementia effect of HS0608 is due to its neuroprotective effect against $A{\beta}$ (25-35)-induced neurotoxicity and that HS0608 may have a therapeutic role in preventing the progression of Alzheimer's disease.

Objectives & Methods : To compare the medicinal herbs between Ayurvedic medicine and traditional Korean medicine(TKM), we took reference of major publications related to Ayurvedic medicinal herbs such as Indian Herbal Remedies, Prime Ayurvedic Plant Drugs, with those of TKM. We selected most widely used 130 herbal species of Ayurvedic medicine and compared the similarities and differences with TKM. Comparative factors were the origin, habitation, synonyms, usage, medicinal parts, and precautions. Results : 1. The medicinal herbs Resinatum Lignum(沈香), Arecae Pericarpium(大腹皮), Arecae Semen(檳榔), Carthami Flos (紅花), Camphorum(樟腦), Crotonis Semen(巴豆), Curculiginis Rhizoma(仙茅) used in TKM did exactly correlate in their origins with those of Ayurvedic medicine. 2. Varieties of allied species were found in their origins. Benincasae Pericarpium(冬瓜皮), and Benincasae Semen(冬瓜子) derive from the same plant Benincasa hispida Cogn. for both Ayurvedic medicine and TKM. Interestingly, B. cerifera Savi. is also claimed for same uses in Ayurvedic medicine. This broadened use of allied species is found in various Ayurvedic herbal medicine such as Cannabis Semen(火麻仁) using Cannabis indica Lam., and Curcuma Longae Rhizoma(薑黃) using Curcuma domestica Valeton. This suggests the possibility of their usage also in TKM. 3. Myrrha(沒藥), and Curculiginis Rhizoma concorded their usage with TKM. While Arecae Pericarpium(大腹皮), Arecae Semen(檳榔), Aquilariae Resinatum Lignum(沈香), Pericarpium(冬瓜皮), Benincasae Semen(冬瓜子), Cannabis Semen(火麻仁), Carthami Flos(紅花), Camphorum(樟腦), Crotonis Semen(巴豆), Curcumae Radix(鬱金), Curcuma Longae Rhizoma(薑黃) and Zedoariae Rhizoma(莪朮) revealed varied efficacies according to their part used or usage forms. Conclusion : Both Ayurvedic medicine and TKM reflect the traditional medicine of its regions where is founded. Mutual understanding improves the capability of coping of diverse ailments of present days and also replacing some plants in the days of increasing threat to our environment. Abundant external applications of various plants found in Ayurvedic medicine were particularly useful for TKM to complement its strength in herbal intake.

The reference herbal extracts and their identification methods by Korean Pharmacopoeia IX were established based on the organic solvent extracts to detect their marker compounds. However, most of herbal medicine decoctions in the market are prepared with water as extracting solvent. As the reference herbal extracts and their identification methods are not appropriate for the practical test, new preparation of alternative reference herbal extracts and their identification test methods are essential for the correction of test methods and identification of herbal drugs. Three novel identification test methods were developed for Evodiae Fructus, Cimicifugae Rhizoma and Aurantii Fructus Immaturus. Total 10 reference herbal extracts and their identification methods were optimized for Ephedrae Herba, Schisandrae Fructus, Curcuma longae Rhizoma, Citri Unshius Pericarpium, Puerariae Radix, Corni Fructus, and Cinnamomi Cortex.

Objectives: We performed this study to evaluate the antioxidative and hypolipidemic effect of Artemisia iwayomogi (韓茵蔯), Curcuma longa L. (鬱金) and Raphanus sativus L. (蘿?子) (ACR). Method: We enriched Artemisiae Capillaris, Curcumae Longae and Raphani Semen compound with alcohol. ACR extract is treated to HepG2 cell. Cell groups are devided into 3 groups: normal, control and ACR treated group. We measured polyphenol, flavonoids, DPPH and ABTS radical scavenging activity, ROS, glutathione, GSH peroxidase, GSH reductase, SOD, catalase, free fatty acid, lipid peroxidation and suppression of ACAT1 and HMG-CoA reductase expression on mRNA level. Results: 1. ACR contained polyphenol and flavonoids and increased GSH significantly in HepG2 cell. 2. ACR increased GPx, GR, and catalase activity significantly in HepG2 cell. 3. ACR increased DPPH and ABTS radical scavenging activity significantly in HepG2 cell and decreased ROS. 4. ACR decreased free fatty acid and MDA significantly in HepG2 cell. 5. ACR suppressed ACAT1 and HMG-CoA reductase expression on mRNA level in HepG2 cell. Conclusion: This study suggests that ACR has antioxidative and hypolipidemic effect and might be effective in prevention and treatment of dyslipidemia.
