In the present study, the anticonvulsant effects of Artemisia capillaris Herba (AC) and its major constituent, esculetin (ECT), were tested and the mechanism studied. Locomotion, Myorelaxation, motor coordination and electroshock seizure experiment were conducted in mice. To identify the anticonvulsant mechanism effect of this drug, chemical-induced seizure in mice and the ionic movement in neuroblastoma cells were also observed. The ethanol extract of AC was orally administered to mice 30 min. prior to testing and ECT was intraperitoneally injected. AC and ECT treatment did not change locomotor activities as well as activities on the rota-rod, which indicates that they did not cause a sedative and myorelaxation effect. AC and ECT treatment increased threshold of convulsion induced by electroshock. AC treatment also inhibited convulsion induced by pentylenetetrazole. In the case of strychnine however, only high dose of AC treatment inhibited convulsion. AC and ECT treatment increased the $Cl^-$ influx into the intracellular area in a dose-dependent manner. On the other hand, bicuculline, a GABA antagonist, inhibited the $Cl^-$ influx induced by AC and ECT. These results indicate that ECT induces the anticonvulsive effect of AC extract through the GABAergic neuron.

Purpose: Intravenous sedation with midazolam is common in contemporary dentistry. That is effective for anxious patients, but additional analgesic agent needs to be used, because midazolam alone doesn't have an analgesic effect. This study was performed to select an analgesic agent between an opioid agent, and nonsteroidal anti-inflammatory drugs as adjunctives in intravenous sedation with midazolam. Methods: The subjects were 60 patients who visited the Department of Oral and Maxillofacial Surgery, Sacred Heart Hospital, Hallym University, between August 2009 and February 2010. Conscious sedation was performed on 20 patients of 3 groups (control group, ketorolac group, and fentanyl group), who were divided randomly. The analgesic agent was administrated preoperatively. For sedation, vital signs were recorded. After sedation and operation, subjective questionnaires of the patient and operator were implemented. Results: All of the $SPO_2$, blood pressure, and heart rates stayed within the normal range for sedation. The sedation depth and analgesic effect of the ketorolac group and fentanyl group were similar. In the case of sedation depth, 12 patients in the ketorolac group and 14 patients in the fentanyl group had no memory of surgery. In the case of analgesic effect, the visual analogue scale of pain scored 2~3 in 13 patients in the ketorolac group, and 0~2 in 12 patients in the fentanyl group. The satisfaction of patients and doctors was also similar. Conclusion: Considering the management and complication of an opioid agent, non-steroidal anti-inflammatory drugs is more effective than an opioid agent.

Chloral hydrate is one of the most widely used sedative agents to control the difficult to treat young age group in the dental clinic. We are often frustrated to see the patient still awake and cry with agitation even after far more than the normal onset time. In such a case, the patient has to be rescheduled for another sedation visit with different agents and/or routes which greatly disappoints the guardians. This case report presents a sedative regimen that can possibly help the clinician complete scheduled treatment without postponement. We have tried sleep induction with Enflurane (1-1.5vol%) for 60 seconds to 37 patients of those who failed to respond properly to the dose(70mg/kg)of oral Chloral hydrate. The average age and weight of the patients was 34.3 months(22-43mo.) and 14.9kg(11-21kg) respectively. It is suggested that sleep induction with low dose Eflurane produced a stable state during dental treatment with respect to vital sign and behavior. Evidence of adverse effect was not detected or reported during and/or after the procedures.

The purpose of this study was to examine the effects of conscious sedation on pain and anxiety of patients in implant surgery. A total of 95 patients who underwent implant surgery were included in the study. In this study, the patient's anxiety and pain to evaluate the pre-operative Visual Analogue Scale (VAS), during-operative Pain Question (PQ), post-operative (Short-form McGill Pain Questionnaire [SF-MPQ], VAS) was used for tools such as questionnaires. The data were analyzed using the chi-squire, independent-samples t-test, multiple linear regression analysis. As a result, the pain reduction was significantly different between the sedative dental treatment and non-sedative dental treatment (p<0.05). The finding of the study multiple linear regression analysis showed that operation time, implant surgery experience, gender, age, operation form and Pain Catastrophizing Scale (PCS) with factors that affect the pain and anxiety (p<0.05). According to the results of the study, considered to be necessary to develop intervention strategies effective using the PCS when managing pain and anxiety of behavior management of this implant patient. Thus, it is advised to provide necessary practical guidelines and dental utilization behaviors on patients with conscious sedation.

Purpose: Abrupt abstinence from alcohol in cause of chronic alcohol addiction can trigger alcohol withdrawal syndrome. The authors studied the effect of post-operative alcohol withdrawal syndrome in patients who require intensive care due to trauma. Methods: For the study group, we selected 70 patients who had undergone emergency surgery from May 2003 to March 2007 due to trauma and who had been treated with prophylactic thiamine. Data was collected retrospectively. We excluded those who extended their hospital stay for other than traumatic causes, those who died within 3 days of surgery after trauma, those who transferred to other institutions, and those who received a psychiatric diagnosis. Patient groups were determined by the existence or the non-existence of withdrawal syndrome. Age, sex, injury mechanism, mortality, complications, durations of hospital stay and intensive care, use of mechanical ventilator, and sedative use were investigated. A Chi-square test and The Mann-Whitney method were used for statistical analysis in this study. Results: Twenty-four (24) patients from the 58 who had an ISS of 16 or more showed alcohol withdrawal syndrome, and men were shown to be affected with the syndrome significantly more than women. Although ISS was higher in the group with alcohol withdrawal syndrome, statistically, the difference was not significant (P<0.08). The total hospital stay in the patient group with alcohol withdrawal syndrome was on average 10 days longer. However, the difference was not significant (P<0.054). The duration of intensive care in the patient group with alcohol withdrawal syndrome was significantly longer (P<0.029). The patients with alcohol withdrawal syndrome showed no significant difference in the duration of mechanical ventilator use (P<0.783), or in the duration of sedative use (P<0.284). Respiratory distress, pneumonia, upper airway infection, sepsis, acute renal failure, and mortality in the alcohol withdrawal syndrome group were investigated, but no statistically significant difference were noted. Conclusion: We found that the duration of intensive care in chronic alcohol abusers was longer due to the development of alcohol withdrawal syndrome. We also discovered that, when the patients overcame the symptoms of alcohol withdrawal syndrome after intensive care, no difference was found in the frequency of developing complications, the morbidity, and the mortality. Therefore, we conclude that intensive care in trauma patients who are chronic alcohol abusers decreases the incidence of complications found in patients with post-operative alcohol withdrawal syndrome and does not adversely impact the prognoses for those patients.

Acanthopanax koreanum Nakai (Araliaceae) is a medicinal plant indigenous to Korea. The root and stem barks of Acanthopanax species have been used as a tonic and sedative as well as in the treatment of rheumatism and diabetes. In our study, three lignans, eleutheroside E (EE), tortoside A (TA), and syringaresinol (SY), were isolated from the stem and root of A. koreanum in an effort to study the immunomodulating effect. We treated natural killer cells and dendritic cells with lignans (EE, TA, or SY), and analyzed their cytokine (IL-12 and IFN-${\gamma}$) secretion. EE, TA, or SY markedly enhanced IL-12 secretion in mouse lymphoid (DC1) and myeloid type (DC2.4) dendritic cells after 48 hr of treatment. There were no significant differences in the cytokine stimulatory effects between EE, TA, or SY. Moreover, treatment of EE, TA, or SY significantly induced IFN-${\gamma}$ secretion by human NK cells (NK92MI) confirmed by ELISA assay. This study suggests that lignans from A. koreanum modulate cytokines, and that such modulation may provide the mechanism of action for many of their therapeutic effects.

Sasa borealis has long been used in folk remedies and traditional Korean medicine for analgesic, sedative and anticarcinogenic purposes. To excavate novel natural compounds for treating obesity, we separated leaf and stem and fractionated. We screened phenolic contents, anti-oxidative and anti-inflammatory properties with the fractions. Dichloromethane (DCM) and ethyl acetate (EA) fraction from both leaf and stem exhibited high anti-oxidative properties demonstrated by DPPH, ABTS assay in accordance with their phenolic contents. In addition, DCM and EA fraction from leaf inhibited nitric oxide (NO) production as well as inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in Raw 264.7 cell. Finally, DCM and EA fraction from both leaf and stem significantly inhibited 3T3-L1 preadipocyte differentiation and decreased intracellular lipid level. These results suggest that DCM and EA fraction from Sasa borealis may contain therapeutic agent for obesity by attenuating inflammation and oxidative stress.
