Objectives : The purpose of this study was to compare the efficacy of Needle-Embedding Therapy with Acupuncture for Chronic Tension-type Headache (CTTH) patients. Methods : The study recruited Chronic Tension-type Headache patients. A total of twenty-six patients were divided into 2 groups. 13 subjects were placed into a needle-embedding therapy group and 13 subjects into an acupuncture therapy group by a randomization table. The needle-embedding therapy group was treated with needle-embedding at Fengchi (GB20), while the acupuncture therapy was acupunctured at Fengchi (GB20). Then, a comparative analysis was conducted by comparing the results with those measured by a Blood pressor, Heart rate variability (HRV), Henry Ford Headache Disablity Inventory (HDI) Internet Headache Impact Test (HIT), and Visual Analogue Scale (VAS). Results & Conclusions : As a result of evaluation by using the self-rating headache index (VAS, HDI, HIT), pain score declined in both groups. But they were not difference between the two groups.

Objectives : The main aim of this study was to assess the comparative efficiency of two preparation types of Hwangryunhaedok decoction(HRHD-D) using distilled and mixed extraction by measuring the index components and indicators of antioxidant and anti-inflammatory effects. Methods : The antioxidant activity was assessed by comparing distilled and mixed extractions of HRHD-D using an ELISA reader. The anti-inflammatory effect was determined by measuring NO amounts in RAW 264.7 cells. The contents were analyzed with high performance liquid chromatography-diode array detector(HPLC-DAD). Results : The electron donating ability of mixed and distilled extractions obtained with 500 ppm DPPH(1,1-diphenyl-2-picrylhydrazyl assay) solution were 57.8 % and 4.2 %, respectively. The total phenolic content of mixed extraction was 6.9 times that of distilled extraction and total flavonoid content was 51.5 times higher. The anti-inflammatory effect was assessed by NO measurement, and was found to increase significantly dependent on concentration in all mixed extract concentrations(25, 50, 100, 200, $400{\mu}g/mL$), but the difference in distilled extraction by concentration was only significant at 200 and $400{\mu}g/mL$. The HPLC analysis results of mixed extract of HRHD-D showed detection of all four main active constituents of HRHD-D. However, they were not detected in the distilled extract of HRHD-D. Conclusions : Mixed extraction with distillation added to decoction of HRHD-D showed better efficacy in antioxidant and anti-inflammatory effects, and ingredient quantities compared to distilled extraction. Further stability and clinical efficacy studies for standardization of mixed extractions are required.

Lamivudine, an oral nucleoside analogue, effectively inhibits hepatitis B virus replication and reduces hepatic necroinflammation in patients with chronic hepatitis B. Although lamivudine has shown a promise in patients with chronic hepatitis B, a long-term data on Korean patients with hepatitis B are lacking. The purpose of this study is to evaluate the effects and safety of 52-week lamivudine therapy in Korean patients with chronic hepatitis B, A total of twenty-nine patients (27 male and 2 female) who had received 100 mg of oral lamivudine daily for 52 weeks were evaluated, retrospectively. The mean age of 29 patients in the study group was 37.7 $\pm$ 8.9 years (range 19-54). Pretreatment HBV PCR and HBsAg were positive in all 29 patients, and HBeAg were positive in 25 patients (86%). The serum HBV DNA of 28 patients (97%) significantly fell to undetectable levels (<5 pg/ml) within 12 weeks of therapy and it remained undetectable in 24 patients (83%) by the end of 52-week therapy (p<0.001). Mean serum ALT levels of 29 patients declined to the normal range within 12 weeks and remained within the normal range during the evaluative period (p<0.05). The proportions of patients with HBeAg seroconversion (loss of HBeAg, development of antibody to HBeAg, and undetectable HBV DNA) were 42% after 52-week therapy. The differences of response to lamivudine therapy in HBeAg- positive and HBeAg-negative patients were negligible (p>0.05). Furthermore, the study showed that pretreatment serum HBV DNA and ALT levels have no effect to the efficacy of lamivudine therapy (p>0.05). Further comparison of lamivudine's efficacy showed that lamivudine is just as efficacious in patients with cirrhosis as without cirrhosis (p>0.05). In conclusion, lamivudine is an effective and safe therapy for the treatment of chronic hepatitis B in Korean patients.

Background: Genicular nerve neurolysis with phenol and radiofrequency ablation (RFA) are two interventional techniques for treating chronic refractory knee osteoarthritis (KOA) pain. This study aimed to compare the efficacy and adverse effects of both techniques. Methods: Sixty-four patients responding to diagnostic blockade of the superior medial, superior lateral, and inferior medial genicular nerve under ultrasound guidance were randomly divided into two groups: Group P (2 mL phenol for each genicular nerve) and Group R (RFA 80℃ for 60 seconds for each genicular nerve). The numeric rating scale (NRS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were used to evaluate the effectiveness of the interventions. Results: RFA and phenol neurolysis of the genicular nerves provided effective analgesia within groups at 1 week, 1 month, and 3 months compared to baseline. There was no significant difference between the groups in terms of NRS and WOMAC scores at all measurement times. At the 3rd month follow-up, 50% or more pain relief was observed in 53.1% of patients in Group P and 50% of patients in Group R. The rate of transient paresthesia was 34.4% in Group P and 6.3% in Group R, and this was significantly higher in Group P. Conclusions: Neurolysis of the genicular nerves with both RFA and phenol is effective in the management of KOA pain. Phenol may be a good alternative to RFA. Further studies are needed on issues such as dose adjustment to prevent transient paresthesia response.

Background : The personnel of emergency department have been under tremendous pressure to manage unexpected emergency situations and excited patients. And interpersonal conflict has existed always, because emergency department was consisted of various personnel of their own specialty. The patient's satisfaction has to come from the personnel's satisfaction. The purpose of this study was to evaluate emergency department personnel's job satisfaction and its related factors and to improve quality of emergency medical service Methods : A self-administered questionnaire survey to the emergency department personnel was conducted between September 1 and October 31, 2001. The response rate was 90.2%. Using SAS program (Version 6.12), the collected data was analyzed by frequency, ANOVA, multiple comparison, Pearson correlation procedure, and stepwise multiple regression analysis. Result : The analysis of related factors of job satisfaction showed high score of interpersonal interaction (3.246), professional prestige (3.095), autonomy (2.916), task requirements (2.701), organizational requirements (2.444), and pay (1.953) in order of item mean. Professional prestige (0.498), task requirements (0.464), and organizational requirements (0.408) were highly positive correlated with overall level of job satisfaction. The factors influencing the job satisfaction were professional prestige and task requirements which explaining efficacy were 37.6% and 32.2% respectively. The total explaining efficacy was 33.6%. Conclusion : It was found out that emergency department personnel's job satisfaction can be raised by promoting professional prestige and task requirements. The personnel of emergency department have to be satisfied through their job, and the administration of the hospital has to pay more attention to their employees' job satisfaction and it related factors.

PURPOSE. This study aimed to investigate the efficacy of cleaning solutions on saliva-contaminated zirconia in comparison to air-abrasion in terms of resin bonding. MATERIALS AND METHODS. For saliva-contaminated air-abraded zirconia, seven cleaning methods)-no contamination (NC), water-spray rinsing (WS), additional air-abrasion (AA), and cleaning with four solutions (Ivoclean [IC]; 1.0 wt% sodium dodecyl sulfate [SDS], 1.0 wt% hydrogen peroxide [HP], and 1.0 wt% sodium hypochlorite [SHC])-were tested. The zirconia surfaces for each group were characterized using various analytical techniques. Three bonded resin (Panavia F 2.0) cylinders (bonding area: $4.5mm^2$) were made on one zirconia disk specimen using the Ultradent jig method [four disks (12 cylinders)/group; a total of 28 disks]. After 5,000 thermocycling, all specimens were subjected to a shear bond strength test with a crosshead speed of 1.0 mm/minute. The fractured surfaces were observed using an optical and scanning electron microscope (SEM). RESULTS. Contact angle measurements showed that groups NC, AA, IC, and SHC had hydrophilic surfaces. The X-ray photoelectron spectroscopy (XPS) analysis showed similar elemental distributions between group AA and groups IC and SHC. Groups IC and SHC showed statistically similar bond strengths to groups NC and AA (P>.05), but not groups SDS and HP (P<.05). For groups WS, SDS, and HP, blister-like bubble formations were observed on the surfaces under SEM. CONCLUSION. Within the limitations of this in vitro study, some of the cleaning solutions (IC or SHC) were effective in removing saliva contamination and enhancing the resin bond strength.

Purpose: To compare the efficacy and toxicity of gemcitabine versus docetaxel in a second-line setting of nonsmall cell lung cancer (NSCLC) patients previously treated with platin-based combination chemotherapy. Materials and Methods: We retrospectively evaluated the medical records of 57 patients treated with single agent gemcitabine or docetaxel in second-line setting of advanced NSCLC who received one prior platinum-based therapy. Results: The mean age was $56.7{\pm}8.39$ years with 55 (96.5%) males and two (3.5%) females. Forty of them received docetaxel and 17 gemcitabine. The mean number of chemotherapy cycles was $6.8{\pm}4.0$ in the gemcitabine group, while it was $4.6{\pm}3.0$ in the docetaxel group. Overall response rates were 8% and 12% (P=0.02) for gemcitabine and docetaxel, respectively. The median survival time was 22 versus 21 months for gemcitabine and docetaxel, respectively. The median times to progression were 8 and 5 months. There was no difference between the two groups in terms of incidence of adverse affects (40% vs 47.1%). All of the hematological side effects were grade 1/2. No major toxicity was encountered necessitating stopping the drug for either group. Conclusions: Treatment with gemcitabine demonstrated clinically equivalent efficacy with a significantly improved safety profile compared with those receiving docetaxel in the second-line setting for advanced NSCLC in this study. Based on these results, treatment with gemcitabine should be considered a standard treatment option for second-line NSCLC.

Objectives : This study was performed to compare the effects of Shinbaro pharmacopuncture therapy and bee venom pharmacopuncture therapy in lumbar disc herniation Methods : We compared treatment efficacy of 12 patients with Shinbaro pharmacopuncture therapy and 10 patients with bee venom pharmacopuncture therapy, all of whom were diagnosed with lumbar disc herniation using computed tomography(CT) or magnetic resonance imaging(MRI). We performed a retrospective comparison and analysis during the course of 21 days since admission. To evaluate the treatment efficacy, we recorded the temperatures of the opposite back, hip, and legs with visual analog scale(VAS, back and legs), pain rating scale(PRS), Oswestry disability index(ODI) and digital infrared thermal imaging(DITI) based on patients' medical records. Results : Both treatments were effective in reducing pain and improving functions for lumbar disc herniation patients in terms of VAS, PRS, ODI, DITI. Shinbaro pharmacopuncture group showed slightly better results than the bee venom pharmacopuncture group, but the difference was not significant. Conclusions : For the treatment of lumbar disc herniation, it is suggested that Shinbaro pharmacopuncture therapy is thought to be as effective as bee venom pharmacopuncture therapy without side effects, although further study would be necessary.

Background Some of the relatively newer, more efficacious, and potent topical wound dressing solutions include tetrachlorodecaoxide and super-oxidised solution. This study compares the efficacy and safety of these two drugs. Methods This is a block-randomised, double blind, parallel-arm, post-marketing study. One hundred fifty patients with ulcers (75 blocks uniform for sex, ulcer aetiology, diabetes mellitus, and wound area score) were randomised into the two treatment arms. Patients were observed for eight weeks with weekly assessments. One hundred and twenty patients completed the study. Wound healing was objectively assessed by measurement of wound area, scoring of wound exudation and tissue type, and using the pressure ulcer scale of healing Tool (validated for multiple wound aetiologies). Subjective improvement in pain was noted using a visual analogue scale. Both groups were compared using Mann-Whitney U test on all indicators. Results Difference in change in wound tissue type in the two groups was significant (${\alpha}$=0.05) by intention-to-treat (ITT) and per-protocol (PP) analysis at the end of week two (ITT and PP, P<0.001) and week four (ITT, P=0.010; PP, P=0.009). P-values for other comparisons were not significant (P>0.05). No study-related adverse events were observed. Conclusions Both drugs are efficacious. Tetrachlorodecaoxide yields healthy granulation tissue earlier. Both drugs appear to be safe for application.

The analgesic efficacy and side-effects of combined continuous epidural infusion of bupivacaine and morphine, in comparison with intramuscular (IM) administration of narcotics, for postoperative pain relief after cesarean section and hysterectomy were evaluated. We divided 60 patients into 4 groups randomly. IM (meperidine) group after cesarean section (Group 1, n = 20); Continuous epidural group after cesarean section (Group 2, n=20); IM (meperidine) group after hysterectomy (Group 3, n=10); Continuous epidural group after hysterectomy (Group 4, n=10). Following each operation, the epidural groups had an epidural catheter placed ($L_{2{\sim}3}$ or $L_{3{\sim}4}$), and a bolus of 1.5mg of morphine was injected, and followed by continuous infusion of 0.3% bupivacaine 2ml/hour and morphine 2.5mg/day for 48 hours. The IM groups had received meperidine 50mg IM injection every 4 hours as needed. We evaluated analgesic efficacy with VAS (visual analogue scale) at 1, 2, 24, 48, and 72 hours after operation. The side-effects (nausea &, vomiting, respiratory depression, pruritus and urinary retention) were evaluated with 4 points scale at day 1, 2, and 3 after operation. The results were as follows 1) The continuous epidural (bupivacaine+morphine) groups were superior to the IM (meperidine) groups with respect to postoperative analgesia at 1, 2, and 24 hours after cesarean section, and at 1, 2, 24, and 48 hours after hysterectomy. 2) Vomiting were more frequent in the epidural groups 2 days after cesarean section. 3) Pruritus was more frequent in the epidural groups 1 and 2 days after cesarean section.
