Objectives & Method : We investigated toxicity, poisoning symptoms, poisoning treatment and prevention against poisoning of herbal medicines used to activate blood flow and remove blood stasis(活血祛瘀藥) in order to use herbal medicines accurately. Result : Cnidii Rhizoma(川芎), Olibanum(乳香), Myrrha(沒藥), Corydalis Tuber(玄胡索), Zedoariae Rhizoma(莪朮), Salviae Miltiorrhizae Radix(丹參), Polygoni Cuspidati Radix(虎杖根), Leonuri Herba(益母草), Persicae Semen(桃仁), Carthami Flos(紅花), Manitis Squama(穿山甲), Eupolyphaga(蟅蟲), Hirudo(水蛭), Vaccariae Semen(王不留行), Sappan Lignum(蘇木), Lacca Sinica Exsiccata(乾漆), Draconis Resina(血竭) and Leonuri Semen(茺蔚子) may give rise to some side effects or toxic symptoms in herbal medicines used to activate blood flow and remove blood stasis(活血祛瘀藥). The representative methods of poisoning treatment in western medicines are washing out the stomach, promotion of vomiting, causing diarrhea, supplies of grape sugar and symptomatic treatment, etc. The representative methods of poisoning treatment in oriental medicine take advantage of herbs. And Oriental medical doctor should meet symptoms as patients call for attention. In order to prevent against poisoning of herbal medicines used to activate blood flow and remove blood stasis (活血祛瘀藥), the patients should keep usage, dosage and notes and oriental medical doctors should do processing drugs. Conclusion : We should pay attention to clinical using of Cnidii Rhizoma(川芎), Olibanum(乳香), Myrrha(沒藥), Corydalis Tuber(玄胡索), Zedoariae Rhizoma(莪朮), Salviae Miltiorrhizae Radix(丹參), Polygoni Cuspidati Radix(虎杖根), Leonuri Herba(益母草), Persicae Semen(桃仁), Carthami Flos(紅花), Manitis Squama(穿山甲), Eupolyphaga(蟅蟲), Hirudo(水蛭), Vaccariae Semen(王不留行), Sappan Lignum(蘇木), Lacca Sinica Exsiccata(乾漆), Draconis Resina(血竭) and Leonuri Semen(茺蔚子) in herbal medicines used to activate blood flow and remove blood stasis(活血祛瘀藥).

Objectives : It has been known to be correlated between phlegm and dementia from the perspective of oriental medicine, but it is unexplored whether herbal medicines to treat phlegm have pharmacological actions on Alzheimer's disease (AD). The aim of this study was to evaluate and to compare effects of herbal medicines to treat phlegm against AD in vitro. Methods : We selected 11 herbal medicines which treat phlegm and obtained each extract by boiling in 10-fold distilled water for 2 h. And we performed the assay of acetylcholinesterase (AChE) inhibitory effects of 11 herbal extracts. Next, we evaluated neuroprotective effects of them against amyloid $beta_{25-35}$ ($A{\beta}_{25-35}$) plaque-induced toxicity in HT22 mouse hippocampal neuronal cells using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. To investigate whether they show the anti-inflammatory effects against lipopolysaccharide (LPS), we also measured the levels of nitric oxide (NO) in BV2 microglia cells using griess reagent assay. Results : We found that Gamiyeongsin-hwan (GYH) and Cheonghunhwadam-tang (CHT) exhibited remarkable AChE inhibitory effects. In HT22 cells, Arisaematis Rhizoma, Trichosanthis Semen and Fritillariae Thunbergii Bulbus suppressed $A{\beta}_{25-35}$ plaque-induced neuronal cell death. In BV2 cells, Cheongung-hwan significantly inhibited the increase of NO contents induced by LPS and GYH and CHT showed a tendency to inhibit LPS-induced NO generation. Conclusions : These results suggest that several herbal medicines to treat phlegm showed the significant effects on AChE inhibition, neuroprotection against $A{\beta}_{25-35}$ plaque-induced toxicity, and inhibition of NO generation. Therefore, we demonstrate the possibility that herbal medicines with treating phlegm has effects against AD.

Objectives : This study was conducted to analyze the single dose toxicity of Mecasin (Gami-Jakyak Gamcho buja Decoction) herbal acupuncture administered in the vein of Sprague-Dawley rats. Methods : All experiments were performed at the Medvill, an institution licensed to conduct nonclinical studies, under the Good Laboratory Practice (GLP) regulations. Sprague-Dawley rats were chosen in this pilot study. In the experiment, Sprague-Dawley rats were divided into four groups of five male and five female animals per group. Doses of Mecasin herbal acupuncture, at 0, 500, 1,000, and 2,000 mg/kg, were given to the experimental groups, and a dose of normal saline solution, at 2 ml/kg, was administered to the control group. Mecasin herb acupuncture and normal saline were injected into the vein at once, and we observed mortality, clinical signs, weights, and gross findings for 14 days after injection. This study was conducted under the approval of the Institutional Animal Ethics Committee. Results : There is no death or abnormality in any of the four groups. All groups put on weights favorably. There are no significant gross findings in necropsy examinations. Conclusions : The above results showed that intravenous injection of 500-2,000 mg/kg of Mecasin herb acupuncture did not cause any changes in weight or, in the results of necropsy examinations, in mortalities. Therefore, the toxicity of Mecasin herb acupuncture was not confirmed, and the presumptive lethal dose of Mecasin herb acupuncture was higher than 2,000 mg/kg. The outcomes suggest that treatment with Mecasin herbal acupuncture is relatively safe. Further evaluations on this subject are needed to yield more concrete evidence.

Diabetic Nephropathy is one of the major causes of chronic renal failure. It is a common microvascular complication and clinically defined as the presence of persistent Proteinuria. We studied the effects and change of the renal function of Complex Herbal medication of the 20Diabetic Nephropathy patients. We measured the initial levels of Total Protein, Creatinine Clearance Rate(Ccr), Serum Creatinine(Serum-Cr), Urine Creatinine(Urine-Cr) and HbA1C on admission and followed up the level changes of Total Protein, Ccr, Serum-Cr and Urine-Cr on discharge. The results are following : Complex Herbal Medication does not cause the renal toxicity. The longer hypertension period is, the higher Serum-Cr level and Urine-Cr level. In an older age group, Urine-Cr is lower. 4.From the 'Deficiency in Origin and Excess in Superficiality(本虛表實)'points of view, Complex Herbal Medication improves the Serum-Cr in Diabetic Nephropathy patients. According to this results, it could be suggested that Complex Herbal Medication does not cause the renal toxicity in Diabetic Nephropathy patients and intensive controls of blood sugar, blood pressure and Complex Herbal Medication prevent the renal failure in Diabetic Nephropathy patients with early stage of Microalbumiuria.

Objectives : We investigated the anti-aging effects on skin with 9 Repetitive steaming and fermenting herbal composition extract (FHE). Methods : Herbal composition is comprised of Panax Ginseng, Rehmannia glutinosa, Polygonum multiflorum and Polygonatum Sibiricum. They steamed and fermented with Saccharomyces cerevisiae and Lactobacillus brevis by turns at 9 times. We measured various effects related to skin aging such as scavenging activity against free radical, cell proliferation, collagen synthesis and toxicity of 9 repetitive steaming and fermenting herbal composition extract were evaluated and compared with herbal composition extract (HE). Results : As the number of steaming and fermenting cycle increased free-radical scavenging activity were increased. But cell proliferating ratio was not increased when the number of steaming and fermenting cycle. The FHE could significantly increase the collagen synthetic ratio compared with HE treated group. And, FHE was showed no toxicity at all tested concentrations. Conclusions : The results of our study propose that FHE has good anti-aging effects on skin.
