This study was aimed to establish analytical method of Bi to develop a guideline of the bioequivalence test of tripotassium dicitrato bismuthate (TDB). For this purpose, a simple, specific and sensitive inductively coupled plasma-mass spectrometry (ICP/MS) method were developed and validated in human plasma. Various concentrations of bismuth standard solution (0-25ng/mL) were prepared with distilled water and human blank plasma. To 10mL of the volumetric flasks, 2mL of blank plasma was added with 8ml of distilled water. Bi standard solution was added to prepare the calibration samples and injected into ICP-MS. The plasma samples obtained from volunteers given 3 tablets of bismuth (total 900mg as TDB) were analyzed as described above. As a result, the coefficients of variation were <20% in quantitation limit (0.2 ng/mL) and <15% at the rest of concentrations. The stability test by repeated freezing-thawing cycles showed that the samples were stable only for 24hr. The stability tested for samples with a short-term period of storage at room temperature and pre-treatment prior to the analysis showed very stable over 24hr. In 8 healthy Korean subjects received Denol tablets at the dose of 900mg bismuth, AUC, $C_{max},\;T_{max}$ and half-life $(t_{1/2})$ were determined to be $198.33{\pm}173.78 ng{\cdot}hr/mL,\;64.48{\pm}27.06 ng/mL,\;0.52{\pm}0.21 hr,\;and\;5.15{\pm}2.67 hr$, respectively, from the plasma bismuth concentration-time curves. In conclusion, the method was suitable for the determination of bismuth in human plasma samples and could be applied to bioequivalence test of bismuth tablet.

The previous studies showed that the visual imagery activated the occipital and posterior inferior temporal area of the brain, and the damage to the occipital cortex impaired the visual mental imagery. We studied current-source distribution of electroencephalography (EEG) to observe neuronal activity during imagery tennis playing. Eleven healthy volunteers were enrolled. All volunteers were right-handed males and novices for tennis playing. The mean age of them was 24.9 years. The EEGs were recorded on the scalp electrodes located according to the International 10~20 System. The number of electrodes was 25 channels including subtemporal electrodes. The EEG recording session was 13 min including 5 segments: resting-I, scenery-slide show, resting-II, watching tennis-game video, and imagery-tennis playing. The recoding durations were 3, 2, 3, 2, and 3 min respectively. Five 'artifact free 3-sec segments' were selected in each segment of 'imagery-tennis playing' and 'resting-II'. We did the frequency domain analysis with the EEG segments using a distributed model of current-source analysis. The statistical-nonparametric maps (SnPMs) were obtained between the segments of 'imagery-tennis playing' and the segments of 'resting-II' (p<0.01). The significant change of current-source density was observed only in alpha-2 frequency band (10~12 Hz). The current-sourcedensity was increased in the hippocampus, parahippocampus, and occipital fusiform gyrus in the right cerebral hemisphere (p<0.01). Imaginary-tennis playing may activate the hippocampal-occipital alpha networks of nondominant hemisphere.

In vitro dissolution test and pharmacokinetic study in human volunteers were conducted to evaluate the pharmacokinetic characteristics of 150 mg furbiprofen sustained-release capsule (FPSR-150). As a reference product, 50 mg flurbiprofen conventional-release capsule (FPCR-50) was used. Dissolution tests of two products were run using the paddle method in 450 : 540 (v/v %) mixture of simulated gastric and intestinal fluids (K.P. VI) by adjusting medium pH according to time. FPCR-50 was dissolved very rapidly, and it took about 1.5 hr for FPCR-50 to be dissolved over 90%, whereas 15 hr for FPSR-150. Also, in pharmacokinetic study, ten healthy male volunteers were administered one capsule of FPSR-150 or two capsules of FPCR-50 (FPCR-l00) with randomized two period cross-over study. Significant differences between FPCR-l00 and FPSR-150 were found in mean times to reach peak concentration, mean resident times and mean terminal phase halflives, while not in AUC/Dose (Student's t-test). In ANOVA for AUC/Dose to compare the bioavailabilities of two FP products, there was no significant difference. From the comparison of the simulated steady-state plasma concentration-time curves following multiple medications of FPCR-50 (3 capsules a day, dosing interval=8 hrs) and FPSR-150 (1 capsule a day) based on the above results obtained from single doses of two FP products, it was noted that the medication of FPSR-150 is more useful in clinical application rather than FPCR-50.

Background: At present, the diagnosis of colorectal cancer (CRC) requires a colorectal biopsy which is an invasive procedure. We undertook this pilot study to develop an alternative method and potential new biomarkers for diagnosis, and validated a set of well-integrated tools called ClinProt to investigate the serum peptidome in CRC patients. Methods: Fasting blood samples from 67 patients diagnosed with CRC by histological diagnosis, 55 patients diagnosed with colorectal adenoma by biopsy, and 65 healthy volunteers were collected. Division was into a model construction group and an external validation group randomly. The present work focused on serum proteomic analysis of model construction group by ClinProt Kit combined with mass spectrometry. This approach allowed construction of a peptide pattern able to differentiate the studied populations. An external validation group was used to verify the diagnostic capability of the peptidome pattern blindly. An immunoassay method was used to determine serum CEA of CRC and controls. Results: The results showed 59 differential peptide peaks in CRC, colorectal adenoma and health volunteers. A genetic algorithm was used to set up the classification models. Four of the identified peaks at m/z 797, 810, 4078 and 5343 were used to construct peptidome patterns, achieving an accuracy of 100% (> CEA, P<0.05). Furthermore, the peptidome patterns could differentiate the validation group with high accuracy close to 100%. Conclusions: Our results showed that proteomic analysis of serum with MALDI-TOF MS is a fast and reproducible approach, which may provide a novel approach to screening for CRC.

Objectives : This study was conducted to assess effects of oriental medicine music therapy on heart rate variability(HRV) in normal subjects under mental stress. Methods : 34 healthy volunteers(control group:17, experimental group:17) participate in this study. The volunteers were randomly allocated into two groups. After 10-minutes rest period and instrumentation, both groups performed a mental stress test for 12-minutes. HRV was recorded before and after the mental stress. And then the experimental group applied oriental medicine music therapy for 10-minutes. In the control group, they rested for 10-minutes. And HRV was recorded. Results : After giving mental stress stimulation to both groups, LF and LF/HF ratio were significantly increased and HF, mean HRV were decreased. In experimental group, LF, LF/HF ratio were significantly decreased and HF, SDNN were significantly increased after applying oriental medicine music therapy. In control group, LF was significantly decreased. And LF/HF ratio was decreased and HF, SDNN were increased, but it was not significant. Conclusions : This results show that oriental medicine music therapy could be relatively useful to decrease sympathetic activity and prevent the alteration of autonomic nervous system due to mental stress.

Objective : This study was done to investigate the differences of HRV(Heart Rate Variability) change as the response to the emotional stimulus in each Sasang constitutions. Method : We investigated 44 healthy volunteers consisted of 10 Soyangin, 14 Soeumin and 20 Taeumin. After diagnosing the Sasang constitution by specialist of Sasang medicine, we measured the baseline emotional state(100 sec) before the stimulus, the changing emotional state(100 sec) while fearful film was being played. And we rechecked the emotional state(100 sec) while taking a rest. At last, volunteers checked the questionnaire for emotional response. We analysed ECG data with HRV-time domain and frequency domain analysis. Results : (1) There were no significant difference in Mean-RR , SDNN between each groups. (2) LF of Taeumin group significantly increased by the emotional stimulation compared with other groups. (3) There was no significant difference in TP, HF, normalized LF, normalized HF, but the variation of each period in Taeumin group was bigger than those of other groups. (4) Soeumin group reported that they felt significant disgust-emotion in the questionnaire compared with other groups. Conclusion : Taeumin group showed significant emotional changes on HRV by fear stimulus film.

Background: The new drug HP228 is a cytokine restraining agent with a broad spectrum of anti-inflammatory, analgesic, and antipyretic activity. Six healthy, adult, male volunteers were studied to determine the independent and interactive effects of HP228 and morphine on pain perception. Methods: Two groups of stimuli were applied to each volunteers before drug administration as control, 20 min after morphine and HP228 administration, and 20 min after combined administration of these two drugs. Two adhesive electrically-conducting pads were applied on opposite sides of the arm approximately 8 cm apart. The electrode were connected to an electrical impulse generator and 50 Hz 1 msec pulses of incrementally increasing intensity were delivered at 1 sec intervals. The analgesic endpoints were the current intensity (mA) at which the subject first detected the stimulus (THRESH), the intensity at which the stimulus was first idenfied as being painful (PAIN), and the intensity at which the subject requested that the stimulus be terminated due to discomfort (LIMIT). A second series of stimuli were applied immediately thereafter using 1-sec duration 50 Hz tetanus pulses with increasing intensities at 2~5 sec intervals. Results: There were significant differences between drug treatments (Morphine, HP228, HP228/Morphine) and control (No drugs) in any of the measurements (PAIN, LIMIT) except THRESH with the twitch and tetanus test. Conclusions: The data suggests that HP228 is an analgesic, but it does not appear to interact with morphine in an additive manner.

Purpose: To evaluate the usefulness of shear wave elastography in the diagnosis of oral and maxillofacial diseases. Materials and Methods: Ten patients with oral and maxillofacial diseases and 28 volunteers drawn from our student doctors were examined by shear wave elastography with a 14-MHz linear transducer using an Aplio 300 apparatus (Canon Medical Systems, Otawara, Japan). A statistical analysis of the shear elastic modulus(kPa) of healthy tissue (the sublingual gland, submandibular gland, anterior belly of the digastric muscle, and geniohyoid muscle) in the 28 volunteers was performed using 1-way repeated measures analysis of variance with the Tukey honest significant difference test. The maximum shear elastic modulus(kPa) of 8 patients with squamous cell carcinoma (SCC) and 2 patients with benign lesions was evaluated with the Mann-Whitney U test. The analysis used a 5% significance level. Results: The mean shear elastic modulus of the sublingual gland ($9.4{\pm}3.7kPa$) was lower than that of the geniohyoid muscle ($19.2{\pm}9.2kPa$, P=.000) and the anterior belly of the digastric muscle ($15.3{\pm}6.1kPa$, P=.004). The maximum shear elastic modulus of the SCCs($109.6{\pm}14.4kPa$) was higher than that of the benign lesions($46.4{\pm}26.8kPa$, P=.044). Conclusion: Our results demonstrated the usefulness of shear wave elastography in the diagnosis of oral and maxillofacial diseases. Shear wave elastography has the potential to be an effective technique for the objective and quantitative diagnosis of oral and maxillofacial diseases.
