Three planks of the Triangular position theory was first introduced by Sanghallon(傷寒論) authored by Jang Gi. It is the regulation for the matter of diagnosis of three different clinical symptoms in the causes of exogenous disease. It brought two questions to the scientists. First question is what are the Wind stroke(中風), Affection by cold(傷寒) and the complex form of Wind stroke(中風) and Affection by cold(傷寒) mentioned in Sanghallon. It is related to the theoretical analysis of the causes for the outbreaks of exogenous disease. Second question is what are the characteristics of symptoms to use Gyejitang, Mahwangtang, Daecheongnyongtang according to Sanghallon? It is the matter of clinical skills for dispensing a prescription. Through the theoretically and empirically deepening processes for last two millenniums, those two questions brought us two more problems further. That is, how and by what processes the Six vital substances for humal life outbreaks disease as a energy transformation? And, how the individual peculiarities of human body as a disease container should be treated? In conclusion, it is also a matter of the existence of dialectic medical science.

In order to provide a basis for studying the molecular mechanism of pharmacological action of local anesthetics and to develop a fluorescence spectroscopic method which can detect the microviscosity of native and model membranes using intramolecular excimerization of 1,3-di(l-pyrenyl)propane (Py-3-Py), we examined the effect of lidocaine HCl on the microviscosity of model membranes of phosphatidylcholine fraction extracted from synaptosomal plasma membrane vesicles (SPMVPC). The excimer to monomer fluorescence intensity ratio (I'/I) of Py-3-Py in liquid paraffin was a simple linear function of $T/{\eta}.$ Based on this calibration curve, the microviscosity values of the direct probe environment in SPMVPC model membranes ranged from $234.97{\pm}48.85$ cP at $4^{\circ}C$ to %19.21{\pm}1.11$ cP at $45^{\circ}C.$ At $37^{\circ}C,$ a value of $27.25{\pm}0.44$ cP was obtained. The lidocaine HCl decreased the microviscosity of SPMVPC model membranes in a concentration-dependent manner, with a significant decrease in microviscosity value by injecting the local anesthetic even at the concentration of 0.5 mM. These results indicate that the direct environment of Py-3-Py in the SPMVPC model membranes is significantly fluidized by the lidocaine HCl. Also, the present study explicitly shows that an interaction between local anesthetics and membrane lipids is of importance in the molecular mechanism of pharmacological action of lidocaine HCl.

Objectives : This article reviews a solution preventing the illegal distribution of herbal medicine in common use for food and medicine and risks on public health by conducting safety management of food and medicine. Also, this article would like to contribute to improvement of public health treating diseases in compliance with accurate diagnosis and prescription of Oriental Medicine Doctor("OMD")'s. Methods : An approach in this research can be categorized into two : first, to examine the current administrative situation and problems of herbal medicine in common use for food and medicine based on policy documents of Ministry of Health and Welfare and Korea Food and Drug Adminstration("KFDA") and academic articles of the herbal medicine;second, to find reasonable administrative solutions to solve the problems. Solutions : A solution is to strengthen the management level of herbal medicine in common use for food and medicine by selecting 117 items as target items requiring concentrated management. In case herbal medicine is imported for food, KFDA strengthens the quality management level of herbal medicine by making use of inspection frequency at random, collecting and verifying herbal medicine on the market. However, KFDA decides to maintain current different quality specification system of food and medicine reflecting a civil complaint that quality specification of food and medicine should separately managed according to the purpose of use. Herbal medicine as medicine that is functioned as treating diseases and alleviating symptoms, unlike herbal medicine for food, can cure all kinds of diseases by recovering inner balance of human body, making use of other properties of herbal medicine. Medicine has its own properties. If a doctor uses properties of medicine appropriately, he cures diseases. If a doctor uses herbal medicine inappropriately. he may damage human body. Thus, whether side effects of medicine depend on a doctor who uses herbal medicine. Conclusions : All herbal medicine will be supplied into the market after strict safety control of manufacturers of herbal medicine according to the revised Pharmaceutical Affairs Act, beginning in April, 2012. Thus, people can take safer and more reliable herbal medicine through strengthening safety management of herbal medicine and improving quality and transparency in the distribution system. Herbal medicine should appropriately be prescribed by licensed OMD because herbal medicine is used to treat diseases and alleviate symptoms, unlike herbal medicine for food.

Aristolochic acid (AA) included in the plants Aristolochiaceae have been well known to be nephrotoxic and carcinogenic inducer and to cause renal disease such as Chinese Herb Nephropathy (CHN). In this study, we used a high performance liquid chromatopaphy-mass spectrometry (HPLC-MS) under the positive ion detection mode for the quantitative change of aristolochic acid-I and-II (AA-I and AA-II) in Aristolochiaceae (Aristolochia contorta Bunge, Aristolochia debilis Sieb. et Zucc., Aristolochia fangchi Wu), some related plants (Cocculus trilobus De candolle, Inula helenium Linne, Saussurea lappa Clarke), and its prescriptions (防己茯笭湯, 定喘散) with or without processing. Here, the processing methods and prescriptions in oriental medicine were generally used to alleviate toxicity or alter property of herbal medicines. However, the concentrations of AA-I and AA-II were highly determined in processed material extracts rather than unprocessed those, not measured in some related plants. Also, the concentrations of AA-I and AA-II even at the prescriptions mixed the plants of Aristolochiaceae were detected to range from 0.73 to 2.53 ppm. Thus, the present results suggest that the content of AA-I and AA-II contained to plants of Aristolochiaceae was not reduced by the processing methods or prescriptions which can induce the physico-chemical change and pharmacological transformation in traditional herbal medicines.

In order to search for insulin-like substances from the constituted herbs of Sogal prescriptions, we selected 19 traditional herbs, based on a review of the Donguibogam. The effects of the hot-water extract from the selected herbs on the proliferation and the differentiation of 3T3-L1 fibroblasts were tested. The various water-extracts from Pinellia ternata, Magnolia obovata, Rheum palmatum, Acanthopanax sessiliflorun, Atractylodes japonica and Strychnos ignatii inhibited the proliferation of 3T3-L1 fibroblasts, did not influence entirely in differentiation of 3T3-L1 fibroblasts. Treatment of 3T3-L1 fibroblasts with the extract from Ephedra sinica, Trichosanthes kirilowii, Scrophularia buergeriana and Sophora flavescens significantly increased the differentiation of the cells. In conclusion, these may contain such compounds that play a role of insulin-like action.

The distribution of barbiturates in the model membranes of total lipids (SPMVTL) and total phospholipids (SPMVPL) extracted from synaptosomal plasma membrane vesicles was determined by employing a fluorescent probe technique. The two fluorescent probes 2-(9-anthroyl)stearic acid and 12-(9-anthroyl)stearic acid were utilized as probes for the surface and the hydrocarbon interior of the outer monolayer of the SPMVTL and SPMVPL, respectively. The Stern-Volmer equation of fluorescent quenching was modified to calculate the relative distribution. The analysis of preferential quenching of these probes by barbiturates indicates that pentobarbital, hexobarbital, amobarbital and phenobarbital are predominantly distributed on the surface area, while thiopental sodium has an accessibility to the hydrocarbon interior of the outer monolayer of the SPMVTL and SPMVPL. From these results, it is strongly suggested that the more effective penetration into the hydrocarbon interior of the outer monolayer of the membrane lipid bilayer could result in a higher general anesthetic activity.
