Facial nerve paralysis(or Bell's palsy) which commonly occurs unilaterally, gives rise to paralysis of facial expression muscle. This condition is classified into symptomatic facial nerve paralysis due to intracranial tumor, post operative trauma, etc. and idiopathic facial nerve paralysis. To explain the etiology of idiopathic facial nerve paralysis, many hypothesis including ischemic theory, viral infection, exposure to cold, immune theory etc. were suggested, but there is no agreement at this point. The method to evaluate the facial nerve paralysis, when it occurs, consists of three stage scale method, image thechnics like CT and MRI, laboratory test to examine the antibody titers of viral infection, neurophysiologic test to evaluate the degree and prognosis of paralysis. Treatment includes medication, stellate ganglion block(SGB), surgery, physical therapy and other home care therapy. In medication, systemic steroids, vitamins, vasodilating-drug and ATP drugs were used. SGB was also used repeatedly to attempt the improvement of circulation and to stimulate the recovery of nerve function. Physical therapy including electric acupuncture stimulation therapy(EAST) and hot pack was used to prevent the muscle atrophy. When No response was showed to this conservative therapies, surgery was considered. After treating two patients complaining of Bell's palsy with medication(systemic steroids) and EAST, favorable result was obtained. so author report the case of facial nerve paralysis.

Epilepsy has continued to provide challenges to epileptologists, as a significant proportion of patients continue to suffer from seizures despite medical and surgical treatments. Deep brain stimulation (DBS) has emerged as a new therapeutic modality that has the potential to improve quality of life and occasionally be curative for patients with medically refractory epilepsy who are not surgical candidates. Several groups have used DBS in drug-resistant epilepsy cases for which resective surgery cannot be applied. The promising subcortical brain structures are anterior and centromedian nucleus of the thalamus, subthalamic nucleus, and other nuclei to treat epilepsy in light of previous clinical and experimental data. Recently two randomized trials of neurostimulation for controlling refractory epilepsy employed the strategies to stimulate electrodes placed on both anterior thalamic nuclei or near seizure foci in response to electroencephalographically detected epileptiform activity. However, the more large-scale, long-term clinical trials which elucidates optimal stimulation parameters, ideal selection criteria for epilepsy DBS should be performed before long. In order to continue to advance the frontier of this field, it is imperative to have a good grasp of the current body of knowledge.

Chemoresistance remains the major obstacle to successful therapy of cancer. In order to understand the mechanism of multidrug resistance (MDR) that is frequently observed in lung cancer patients, here we studied the contribution of MDR-related proteins by establishing lung cancer cell lines with acquired resistance against etoposide. We found that human H460 lung cancer cells responded to etoposide more sensitively than A549 cells. Among MDR-related proteins, the expression of p-glycoprotein (Pgp) and lung resistance protein (LRP) were much higher in A549 cells compared with that in H460 cells. When we established H460-R1 and -R2 cell lines by progressive exposure of H460 cells to increasing doses of etoposide, the response against etopbside as well as doxorubicin was greatly reduced in R1 and R2 cells, suggesting MDR induction. Induction of MDR was not accompanied by a decrease in the intracellular accumulation of etoposide and the expression of MDR-related proteins that function as drug efflux pumps such as Pgp and MRP1 was not changed. We found that the acquired resistance paralleled an increased expression of LRP in H460 cells. Taken together, our data suggest the implicative role of LRP in mediating MDR in lung cancer.

This study aimed to know the association between health practices(Alameda 7) and health state according to Sasang Constitution. We recruited 204 subjects whose age were between 10 and 80, excluding individuals who have physically or psychologically serious diseases, and women in pregnancy among Korean population in Traditional Korea Clinics. They were diagnosed by Sasang constitution specialists and confirmed clinically with Sasang constitution drug response with past medical records. We used the 36-Item Short Form Health Survey(SF-36) to estimate health state related with quality of life. We statistically analyzed association using SPSS 17.0K for window. According to Sasang Constitution, smoking and exercising were associated with health degree in Tae-eumin, smoking, drinking, diet and snacking in So-eumin, and past smoking, drinking, sleeping and exercising in So-yangin. These results suggest that there are different health practices for health promotion according to Sasang constitution. Therefore we have to consider the differences of Sasang constitution in health care plan.

Ethanolic extract (50% v/v) and alkaloid fraction of Tylophora indica leaves were examined for lysosomal enzyme inhibitory activity in adjuvant-induced arthritic rats. The alkaloid fraction showed statistically significant inhibition of arthritic lesions (p < 0.05) from day 18, (p < 0.025) from day 20 and (p < 0.001) from day 21 onwards in the adjuvant-induced arthritis, which was comparable to the response of standard drug Indomethacin. The ethanolic extract was less significant than the alkaloidal fraction in inhibition of arthritis. Alkaloid fraction showed significant (p < 0.001) inhibitory effect on the lysosomal enzyme activities in adjuvantinduced arthritic rats. It also significantly prevented decrease in collagen levels and synovial damage observed during arthritis and also inhibited increase in urinary excretion levels of collagen degradation products like hydroxyproline, hexosamine, hexuronic acid, etc. Both ethanolic extract as well as the alkaloid fraction, however, did not show any significant activity in normal nonarthritic rats. The ethanolic extract and the alkaloid fraction may thus be able to inhibit the progress of inflammation and inhibit the destructive activity of lysosomal enzymes on structural macromolecules like collagen etc. in the synovial capsule in joints during arthritic states. They may thus prevent synovial damage observed during arthritis.

Repeated administration of all addictive drugs, including nicotine, can produce sensitization of extracellular dopamine levels in the nucleus accumbens and behavioral sensitization in rat, as evidenced by an enhanced locomotor response and increased dopamine release in brain to a subsequent injection of the drug. In order to investigate the effect of Zizyphus jujuba extract on repeated nicotin-induced sensitization, rats were given repeated injection of saline or nicotine (0.4 mg/kg s.c., twice a day for 7 d), followed by one challenge injection on the 4th day after the last daily injection. Systemic challenge with nicotine (0.4 mg/kg s.c.) and a direct local challenge of 3 mM a larger increase in locomotor activity and extracellular dopamine release in the nucleus accumbens in nicotine-pretreated rats than in saline-pretreated rats, respectively. Zizyphus jujuba extract significantly decreases locomotor activitiy and dopamine release in the nucleus accumbens induced by a nicotine challenge. These results suggest that Zizyphus jujuba extract may attenuate nicotine-induced neurochemical and behavioral sensitization and may be effective in suppressing compulsive nicotine-seeking behavior.

Coronary artery disease is a loading cause of morbidity and mortality across the world. Percutaneous coronary intervention has become the major technique of revascularization. However, restenosis remains a major limitation of this procedure. Recently the need for repeat intervention due to restenosis, the most vexing long-term failure of percutaneous coronary intervention, has been significantly reduced owing to the introduction of two major advances, intracoronary brachytherapy and the drug-eluting stents. Intracoronary brachytherapy has been employed in recent years to prevent restenosis lesions with effective results, principally in in-stent restenosis. Restenosis is generally considered as au excessive form of normal wound healing divided up in precesses: elastic recoil, neointimal hyperplasia, and negative vascular remodeling. Restenosis has previously been regarded as a proliferative process in which neointimal thickening, mediated by a cascade of inflammatory mediators and other factors, is the key factor. Ionizing radiation has been shown to decrease the proliferative response to injury in animal models of restenosis. Subsequently, several randomized, double blind trials have demonstrated that intracoronary brachytherapy can reduce the rates of both angiographic restenosis and clinical event rates in patients undergoing percutaneous coronary intervention for in stent restenosis. Some problems, such as late thrombosis and edge restenosis, have been identified as limiting factors of this technique. Brachytherapy is a promising method of preventing and treating coronary artery restenosis.

Cellular components of Lactococcus lactis ssp. lactis (heat-killed whole cells, cytoplasm, and cell walls) were tested for their in vivo immunopotentiating activities. Peritoneal macrophages from mice injected intraperitoneally with cell-wall fractions exhibited significantly greater phagocytic activity than groups injected with whole cells or cytoplasm fraction. Cytotoxicity of natural-killer cells was highest in cytoplasm fractions. Production of cytokines (IFN-${\gamma}$, IL-2, IL-6, and IL-12) in spleen cells was significantly higher when cellular components were injected intraperitoneally, and tended to be higher in whole-cell and cytoplasm groups than in cell-wall group. These results demonstrate lactic acid bacteria whole cells and their cytoplasm and cell-wall tractions have immunopotentiating activities.

Purpose: This study was carried out to investigate perception and experience of medication errors by nurses. Method: Data collection through a survey was performed using structured questionnaires over the period of September 1 to October 15, 2004. Questionnaire were delivered to 222 nurses from 15 hospitals; thereafter, 205 questionnaires were responded (i.e., 92% response rate). The subject in the study was a nurse who had been working in the hospital for less than one year. Results: The average perception rate was 87.5%. The perception rates of subjects in medication errors from four areas are 62% in wrong dosage form for drug administration, 61.5% in air into an IV set, 63% in crystals in an IV lines, and 83.5% in wrong time. The experience rates of subjects in medication errors from four areas are 85.5% in wrong time, 39.5% in wrong injection site, 34.5% in omission error, and 28% in wrong patient. Conclusion: The average perception rate and experience rates of medication errors were 87.5% and 23.5%, respectively. Education about the Five right in medication and knowledges about drugs would improve the perception of medication errors of nurses whose work experience is less than one year, and prevent them from medication errors.

Dose response of DNA repair synthesis induced by bleomycin was dose-dependent in lower doses, and maximum rate of it at 5 $\\mu$g/ml represents about 15% of total cells analyzed. At higher doses DNA-repair synthesis was reduced and the rate of it remained unchanged even prolonged treatment. Pretreatment with BUdR or IUdR was found to enhance DNA repair synthesis and also to interfere with semiconservative DNA synthesis at higher doses. Time dependence study showed that DNA repair synthesis occurred as long as for 24 hours after removal of bleomycin. These results seem to suggest that bleomycin is not to be an effective chemical in inducing excision repair and that damages induced in DNA by this drug might include not only strand breaks but other types of DNA damage.
