Objectives: To define the difference in the identity of the authors of 『傷寒論』 and 『黃帝內經』 by analyzing the etymology of 巫, 毉, 醫, and 工. Methods: We analyzed the meaning of three Chinese characters based on oracle bones and bronze inscriptions, and considered examples of their utilization in two books. Results:In 『Gangpyeong-Shanghanlun』, 巫appears once, 醫appears 28 times, and 工appears once. In 『Huangdi Neijing』, 巫appears twice, 醫appears 24 times, and 工appears 64 times. Conclusions: The authors of 『傷寒論』 recognized themselves as '醫', and they were doctors who mainly treated prescriptions in the liquid form represented by 湯(tang). The authors of 『黃帝內經』 recognized themselves as '工', and they were doctors who treated them with a tool represented by "acupuncture."

Objective : This study aimed to report the improvement of a patient with chronic rhinitis treated with herbal medication using the disease pattern identification diagnostic system (DPIDS) based on the Shanghanlun provisions. Methods : According to the Shanghanlun DPIDS and an etymological interpretation of Chinese characters, the patient was diagnosed with Reverting yin disease (provision 352) and took Dangguisayeokgaosuyusaengang-tang herbal medication for 50 days. The change in symptoms of chronic rhinitis were estimated using the Total Nasal Symptom Score (TNSS), the Rhinitis Control Assessment Test (RCAT), and a visual analog scale (VAS). Results : The TNSS score decreased from 8 to 3, the RCAT score decreased from 14 to 24, and the VAS decreased from 10 to 2. Conclusions : The main causes of the disease were 厥 and 內. This is the first case report of describing the treatment of chronic rhinitis with Dangguisayeokgaosuyusaengang-tang.

Aralia contientalis show several beneficial effects including anti-oxidant effects. Aralia contientalis is used as a therapeutic agent to stop haemorrhages and a tonic to promoted health in Korean and Chinese medicine. The pharmacokinetic profiles of the main Aralia contientalis is still not accurately investigated. In present study, I examined the effects of water extracts of Aralia contientalis on high cholesterol diet atherosclerosis-induced rats in serum and abdominal aorta. A total of 3-week old 9 male rats of Sprague-Dawley were divided into 3 groups and fed with the basal diet (normal group), high cholesterol diet (atherosclerosis induced group) for 8 weeks, high cholesterol diet supplemented with water extracts of Aralia contientalis (Aralia contientalis group) for 2 weeks. And rats were sacrificed, serum lipid level, abodominal aortic anti-oxidant activities and lipid peroxide were measured. These results indicated that serum total cholesterl, LDL-cholesterol, triglycerides concentration significently lowered in Aralia contientalis group than high cholesterol diet group. But HDL-cholesterol concentraion significently higher in Aralia contientalis group than high cholesterol diet group.

Objectives : ST8SIA2 (ST8 alpha-N-acetyl-neuraminide alpha-2, 8-sialyltransferase 2 gene) is located at 15q26, a susceptibility locus for schizophrenia. Some previous research had indicated that single-nucleotide polymorphisms (SNPs) in the promoter region of ST8SIA2 were associated with schizophrenia in Japanese and Chinese populations. We investigated the association between SNPs in the promoter region of ST8SIA2 and schizophrenia in the Korean population. Methods : The study subjects were 190 Korean patients with schizophrenia and 190 healthy controls. We performed allelic, genotypic, and haplotypic association analyses for rs3759916, rs3759915 and rs3759914 of ST8SIA2. All genotypes were determined by direct sequencing. Results : In the genotype-based analysis, rs3759914 showed a nominally significant association with schizophrenia under recessive genotypic model (p = 0.047). However, this association did not remain statistically significant after correction for multiple testing. Both allelic and haplotype analyses did not show any significant association. Conclusions : These findings suggest that ST8SIA2 does not play a major role in the susceptibility to schizophrenia in the Korean population. Further studies with a larger number of subjects are required to definitively rule out minor effects of this gene on schizophrenia vulnerability.

The aim of this study is to develop a physiologically based pharmacokinetic (PBPK) model in intra-abdominal infected rats, and extrapolate it to human to predict moxifloxacin pharmacokinetics profiles in various tissues in intra-abdominal infected human. 12 male rats with intra- abdominal infections, induced by Escherichia coli, received a single dose of 40 mg/kg body weight of moxifloxacin. Blood plasma was collected at 5, 10, 20, 30, 60, 120, 240, 480, 1440 min after drug injection. A PBPK model was developed in rats and extrapolated to human using GastroPlus software. The predictions were assessed by comparing predictions and observations. In the plasma concentration versus time profile of moxifloxcinin rats, $C_{max}$ was $11.151{\mu}g/mL$ at 5 min after the intravenous injection and $t_{1/2}$ was 2.936 h. Plasma concentration and kinetics in human were predicted and compared with observed datas. Moxifloxacin penetrated and accumulated with high concentrations in redmarrow, lung, skin, heart, liver, kidney, spleen, muscle tissues in human with intra-abdominal infection. The predicted tissue to plasma concentration ratios in abdominal viscera were between 1.1 and 2.2. When rat plasma concentrations were known, extrapolation of a PBPK model was a method to predict drug pharmacokinetics and penetration in human. Moxifloxacin has a good penetration into liver, kidney, spleen, as well as other tissues in intra-abdominal infected human. Close monitoring are necessary when using moxifloxacin due to its high concentration distribution. This pathological model extrapolation may provide reference to the PK/PD study of antibacterial agents.
