  • Objectives : Moxibustion has been become very useful tool to prevent and treat various diseases with acupuncture in oriental medicine. Expecially, moxibustion combining the heat stimulation and chemical stimulation of Artemisiae Argyi has a non-invasive characteristics comparing to the other therapeutic tools. However, because the moxibustion makes the patient's skin be burn by the combustible feature of moxibustion, most of people have been scared of being scald. Methods : In this study, we have developed new non-combustible moxibustion tools in collaboration with company (Hana Medical, co. and ICURE, co.) and tested the efficacy through effects of moxibustion of Cheon-chu $(ST_{25})$ on the abdominal thermography of health subject. The non-combustible moxibustion has main characteristics of controlled heating to inhibit being scald and heat stimulation lasting over 1 hrs. Also, to induce the chemical stimulation, the bottom contacting with skin was coated by the extract of artemisiae argyi. The volunteers who participating in this study had taken rest for 20 - 30 mins in room temperature $(23-25^{\circ}C)$ before the examination and informed them what to prohibit smoking, drinking and administration of drug for the previous day The thermography of abdomen including a below part of the chest was taken using Infra-Red Imaging System (IR 2000, MEDI-CORE Co., Korea) by time interval of 15 minutes. Results : The results showed that moxibustion of Cheon-chu $(ST_{25})$ had more potencies of changes on all the ROIs of abdominal thermography than those of control group. Also, it was observed that the quantities of thermal changes following moxibustion of Cheon-chu $(ST_{25})$ been increased significantly comparing that of control group at all the ROIs (region of interest). Observed the thermography classified by ROI, however, moxibustion of Cheon-chu $(ST_{25})$ could modulate ipsilateral specific areas concerning to the abdominal pathway of Stomach Meridian. Conclusion : These results suggest that new non-combustible moxibusion has some similarity as like as the conventional moxibustion and moxibustion of Cheon-chu $(ST_{25})$ may modulate thermal changes of abdominal areas.

  • In this report, we present a case study of how pharmacogenomics and pharmacometabolomics can be useful to characterize safety and pharmacokinetic profiles in early phase new drug development clinical trials. During conducting a first-in-human trial for a new molecular entity, we were able to determine the mechanism of dichotomized variability in plasma drug concentrations, which appeared closely related to adverse drug reactions (ADRs) through integrated omics analysis. The pharmacogenomics screening was performed from whole blood samples using the Affymetrix DMET (Drug-Metabolizing Enzymes and Transporters) Plus microarray, and confirmation of genetic variants was performed using real-time polymerase chain reaction. Metabolomics profiling was performed from plasma samples using liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. A GSTM1 null polymorphism was identified in pharmacogenomics test and the drug concentrations was higher in GSTM1 null subjects than GSTM1 functional subjects. The apparent drug clearance was 13-fold lower in GSTM1 null subjects than GSTM1 functional subjects (p < 0.001). By metabolomics analysis, we identified that the study drug was metabolized by cysteinylglycine conjugation in GSTM functional subjects but those not in GSTM1 null subjects. The incidence rate and the severity of ADRs were higher in the GSTM1 null subjects than the GSTM1 functional subjects. Through the integrated omics analysis, we could understand the mechanism of inter-individual variability in drug exposure and in adverse response. In conclusion, integrated multi-omics analysis can be useful for elucidating the various characteristics of new drug candidates in early phase clinical trials.

  • The effects of the oriental herbal medicine Saenghyetang(SHT, 生慧湯), which consists of Rehmanniae Radix (熟地黃 九蒸: was made by 9th steam) 40g, Corni Fructus(山茱黃) 16g, Polygalae Radix(遠志) 8g, Zizyphi Spinosae Semen(酸棗仁) 2g, Biotae Semen(柏子仁 去油: oil ingredient was removed) 20g, Poria Cocos(茯笭) 12g, Ginseng Radix(人蔘) 12g, Acori Graminei Rhizoma(石菖蒲) 2g, Sinapis Semen(白芥子) 8g, on learning ability and memory were investigated. Hot water extract(HWE) and ethanol extract(EE) from SHT were used for the studies. Learning ability and memory are related to modifications of synaptic strength among neurons that interactive. Enhanced synaptic coincidence detection leads to improved learning ability and memory. If the NMDA receptor, a synaptic coincidence detector, acts as a graded switch for memory formations, enhanced signal detection by NMDA receptors should enhance learning ability and memory. It was shown that NR2B was increased in the forebrains of oriental medicine-administrated mice, leading to enhanced activation of NMDA receptors and facilitating synaptic potentiation in response to stimulation at 10-100 Hz. These HWE-SHT treated mice exhibited that superior ability in learning and memory when performing various behavioral tasks, showing that NR2B is enhanced by HWE-SHT treatment and also is critical in gating the age-dependent threshold for plasticity and memory formation. NMDA receptor-dependent modifications, which were mediated in part by HWE administration, of synaptic efficacy, therefore, represent a mechanism for associative learning ability and memory. Results suggest that oriental medical enhancement of NR2B contributes to increase intelligence and memory in mammals On the other hand, to examine the effects of EE-SHT on the learning ability and memory in experimental mice, EE-SHT was tested on passive and active avoidance responses. The EE-SHT ameliorated the memory retrieval deficit induced by ethanol in mice, but not other memory impairments. EE-SHT(10, 20mg/100 g, p.o.) did not affect the passive avoidance responses of normal mice in the step through and step down tests, the conditioned and unconditioned avoidance responses of normal mice in the shuttle box, lever press performance tests and the ambulatory activity of normal mice in a normal condition. However, EE-SHT at 20 mg/kg significantly decrease the spontaneous motor activity during the shuttle box test, and also to extend the sleeping time induced by pentobarbital in mice. These results suggest that SHT has an ameliorating effect on memory retrieval impairments and a weak tranquilizing action.

  • Podostroma cornu-damae is a rare species of fungus belonging to the Hyocreaceae family. Its fruit body is highly toxic, as it contains trichothecene mycotoxins. The morphology is similar to that of immature Ganoderma lucidum, making identification difficult for non-experts. We experienced such a case of a 56- year-old male who picked and consumed podostroma cornu-damae, and consumed. Later that day, he developed digestive system symptoms, including nausea, vomiting, and abdominal pain. He presented to the emergency room (ER), there were no abnormal physical findings, symptoms improved after gastric lavage, and the patient voluntarily discharged himself on the same day. The following day, as the symptoms gradually deteriorated, he was admitted via the ER. He was presented with severe pancytopenia, alopecia, desquamation of skin, and acute renal failure. He recovered without any complications after conservative care, antibiotics therapy, and granulocyte colony stimulating factor administration. The most commonly reported complications of podostroma cornu-damae intoxication were reported pancytopenia, infection, disseminated intravascular coagulation, acute renal failure, etc. since Prevention is especially important because its toxicity can be lethal and there is no particular treatment to date, prevention is especially important. Promotion and education for the public are needed.

  • Three dogs with severe traumatic spinal cord injury (TSCI) due to falling wound were admitted to the Veterinary Medical Center, Chonbuk National University for evaluation of severe pelvic limbs paralysis without deep pain, normal defecation and urination. Based on physical examination, neurological assessment and computed tomogram (CT), the diagnosis was made as subluxation and compressed fracture. All the cases were surgically treated with dorsal laminectomy and a spondylosyndesis using pin and bone cements. For 2 weeks, the dogs didn't show any improvement. Consequently, the dogs were treated with electroacupuncture (EA) and Duhuojisheng-tang (DHJST). All the dogs got back the deep pain and presented wagged tail on 14-35 days after starting EA with DHJST. Especially, two of 3 dogs recovered almost normal ambulation and capacities of urination and defecation. But, one dog failed to regain normal ambulation due to inflammation of operative site which is thought to be caused by the bone cement. From these cases, it was thought that the combination of EA and DHJST mightbe one of the suitable therapies in dogs with no neurological improvement.

  • The effect of Bu-Zhong-Yi-Qi-Tang (BZYQT) on the changes of ultraviolet (UV) light B radiation-induced apoptotic sunburn cell (SBC) and epidermal ATPase-positive dendritic cell (DC) in SKH1- hr or ICR mouse were investigated. The mice were treated with UVB (200 mJ/$cm^2$) and were sacrificed 24 h later. BZYQT (50 mg/kg of body weight) or vehicle (saline) was given i.p. at 36 and 12 h before irradiation, and 30 min after irradiation or BZYQT cream (0.2%) or cream base (vehicle) was topically treated at 24 h and 15 min before irradiation, and immediately after irradiation. The skin of SKH1-hr mouse prepared from the back of untreated mice exhibited about 0.3 SBC/cm length of epidermis, and 24 h after UV irradiation, the applied areas show an increased number of SBCs. But the frequency of UVB-induced SBC formation was reduced by intraperitoneal injection of BZYQT extract (p < 0.01). The numbers of DC in normal ICR mouse were 628.00 ${\pm}$ 51.56 or 663.20 ${\pm}$ 62.58 per $mm^2$ of ear epidermis. By 1 day after UVB treatment, the number of ATPase-positive cells/$mm^2$ were decreased by 39.0% or 27.1% in i.p. or topical application group with vehicle. Treatment of BZYQT was associated with increase of 33.9% in i.p. group (p < 0.05) or 2.7% in topical application group in the number of ATPase positive cells compared with the irradiation control group. The results presented herein that BZYQT administration could reduce the extent of skin damages produced by UVB.

  • Anemarrhena asphodeloides BUNGE is one of important medicinal crops, which has been collected or/and cultivated for its rhizomes. The main medicinal ingredient of the A. asphodeloides Bunge rhizomes is a saponin, which is known to have medical values for diaphoresis, sedatives and biuresis. However, studies on cultural methods and breeding works on this plant have not been made in detail. To increase productivity and to improve quality of crops, it is important to collect cultivated and wild lines, to classify them based on morphological and genetic characteristics, and to select superior pure lines at first. Therefore, total 20 A. asphodeloides lines collected were cultivated at the fieldof Chungnam Provincial Administration of Rural Development in 1995 to study the agronomic characteristics and to classify them based on morphological characteristics. Characteristics related with reproductive organ such as the number of spikes per plant and peduncle length showed greater variations than vegetative organrelated characteristics such as leaf length and rhizome length based on the coefficient of variation. Vigorous shoot growth resulted in better development of reproductive organs such as peduncle length and number of spikes per plant. However, the development of spikes was negatively correlated with chlorophyll content. Characteristics of underground parts were more significantly correlated with spike characteristics than aerial part characteristics. A. asphodeloides tested in this study were classified into 2 groups (group A and group B) based on centroid linkage cluster analysis. Group A showed more vigorous shoot growth with more leaves and spikes per plant, longer peduncle length, thicker peduncle diameter and higher shoot dry weight than group B. Group A could be further classified into 2 sub-groups based on leaf size, spike length and peduncle diameter, while group B also could be classified based on number of leaves, number of spikes and shoot dry weight.

  • Triflusal is a new antithrombotic agent which inhibits both platelet cyclooxygenase and c-AMP phosphodiesterase activity. The purpose of the present study was to evaluate the bioequivalence of two triflusal capsules, $Disgren^{TM}$ (Myung-In Pharmaceutical Co., Ltd.) and $Tigriri^{TM}$ (Hana Pharmaceutical Co., Ltd.) according to the guidelines of Korea Food and Drug Administration (KFDA). Eighteen normal male volunteers, $22.94{\pm}1.83$ in age and $63.7l{\pm}10.43$ kg in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After one capsule containing 300 mg of triflusal was orally administered, blood was taken at predetermined time intervals and the concentrations of triflusal in serum were determined using HPLC method with UV detector. Pharmacokinetic parameters such as $AUC_t$ $C_{max}$ and $T_{max}$ were calculated and ANOVA test was utilized for the statistical analysis of the parameters. The results showed that the differences in $AUC_t$ $C_{max}$ and $T_{max}$ between two capsules were -0.30%, 0.81 % and -3.03%, respectively when calculated against the $Disgren_{TM}$ capsule. The powers $(1-{\beta})$ for $AUC_t$ $C_{max}$ and $T_{max}$ were 98.29%,84.73% and 81.02%, respectively. Minimum detectable differences $({\Delta})$ at ${\alpha}=0.1$ and $1-{\beta}=0.8$ were all less than 20% (e.g., 12.91%, 18.46% and 19.65% for $AUC_t$ $C_{max}$ and $T_{max}$ respectively). The 90% confid,ence intervals were all within ${\pm}20%$(e.g., $-8.97{\sim}8.37$, $-11.58{\sim}13.22$ and $-16.23{\sim}10.17$ for $AUC_t$ $C_{max}$ and $T_{max}$, respectively). All of the above parameters ($1-{\beta}, {\Delta}$ and 90% confidence intervals) met the criteria of KFDA for bioequivalence, indicating that $Tigriri^{TM}$ capsule is bioequivalent to $Disgren^{TM}$ capsule.

  • 1. Atropine has recently been known to possess a sympathetic ganglion blocking effect. If atropine blocks the sympathetic ganglia innervating the blood vessels, the drug should cause depressor responses. The author attempted to verify this assumption in urethane-anesthetized rabbits having atropinesterase. 2. Ten and $50{\mu}g/kg$ of atropine produced little variation of the blood pressure; $250{\mu}g/kg$ slight depressor responses; $1,250{\mu}g/kg$ distinct ones. Under hexamethonium-infusion, 10 and $50{\mu}g/kg$ produced observable depressor responses; 250 and $1,250{\mu}g/kg$ produced more pronounced ones. 3. In experiments examining influence of phenoxybenzamine and bretylium on the atropine responses, the lowered blood pressure by these agents was raised by simultaneous infusion of angiotensin with hexamethonium. The depressor responses to atropine (10, 50 and $250{\mu}g/kg$) were slight after the administration of phenoxybenzamine and bretylium. 4. Propranolol did not affect the depressor responses to atropine. 5. In spinalized rabbits the lowered blood pressure was raised by the angiotensin-infusion. In these animals receiving the simultaneous hexamethonium-infusion, atropine (10, 50 and $250{\mu}g/kg$) produced little depressor responses. 6. From these results it is inferred that atropine produced the depressor responses by blocking the sympathetic ganglia innervating the blood vessels.
