The ventral midline approach (VMA) and right flank approach (RFA) are common procedures for the sterilization of bitches. This study compared the different parameters viz. total duration of surgery, recovery time, and length of the incision as well as body temperature, heart rate, respiration rate, and SpO2 in each approach. Twenty (20) bitches were divided randomly for the RFA and VMA. Meloxicam (0.2 mg/kg) was administered subcutaneously half an hour before the induction to provide preemptive analgesia. Diazepam and ketamine were administered intravenously at dose rates of 0.25 mg/kg and 2.5 mg/kg, and 0.17 mg/kg and 3.33 mg/kg, respectively to produce and maintain anesthesia. Each parameter was recorded at the pre-operative, operative and post-operative times. The average duration of surgery and length of incision of RFA (16.1 ± 5.13 min and 2.44 ± 0.83 cm) were significantly lower (p < 0.05) than the VMA (21.3 ± 5.48 min and 3.53 ± 0.7 cm). The operated bitches showed hypothermia (p < 0.05) at 1 hour compared to baseline and 24 hours of surgery. Heart and respiration rates increased significantly (p < 0.05) during traction and severing of ovarian ligaments in bitches within the RFA group, but there was no significant difference within VMA approaches. The sedation score was significantly higher (p < 0.05) at 1 hour after surgery in both approaches. Based on the duration of surgery and length of incision RFA approach was quick and minimal skin wound. Further studies on bitches considering molecular investigations of surgical stress are imperative.

목 적 : 식도 이물의 내시경적 적출의 최근 경향과 내시경적 적출의 유용성에 대해 알아보고 소아에서 유연형 내시경을 통한 식도 이물 제거술이 정착되기를 바라는 마음으로 이 연구를 시작하였다. 방 법 : 1987년 1월부터 2001년 7월까지 14년 6개월간 경상대학교병원 소아과와 이비인후과에서 식도 이물로 진단하여 유연형 내시경과 강직형 내시경으로 치료하였던 127례를 대상으로 하였다. 유연형 내시경의 경우는 소아과에서 Olympus사의 XP-20, XQ-240과 Pentax사의 2731와 다양한 보조 기구를 사용하고 전신마취나 midazolam이나 diazepam 등의 약제는 사용하지 않았다. 결 과 : 1) 연도별 분포 : 1998년까지는 이물의 제거에 강직형 내시경이나 유연형 내시경이 비슷하게 이용되어 왔다. 1999년 이후부터 유연형 내시경에 의한 이물의 제거가 활발히 이루어졌다. 2) 연령별, 성별 분포 : 유연형 내시경을 사용한 경우는 1세 미만의 경우 4례(6%)였고, 1-5세의 경우 43례(65.1%), 5-10세의 경우 17례(25.7%), 10-15세의 경우 2례(3.2 %)로 총 66례였다. 강직형 내시경을 사용한 경우는 1세 미만의 경우 8례(13.5%), 1-5세는 42례(68.8%), 5-10세는 7례(11.5%), 10-15세는 4례(6.6%)로 총 61례였다. 두 경우 모두 1-5세가 호발 연령이었다. 남녀 비를 보면 유연형 내시경을 사용한 경우 1.64 : 1이었고 강직형 내시경을 사용한 경우에는 1.13:1로 남아에서 다소 많았다. 3) 이물의 종류, 증상, 제거까지 걸린 시간 및 합병증 : 이물의 종류로는 유연형 내시경으로 제거한 경우는 54례, 강직형 내시경으로 제거한 경우 42례로 동전이 제일 많았고 임상 증상은 유연형 내시경의 경우에는 무증상이, 강직형 내시경의 경우에는 연하 곤란이 제일 많았다. 식도 이물을 제거까지 걸린 시간은 대부분 이물을 삼킨 후 24시간 이내였다(108례, 85%). 24시간 이후에 이물을 제거 한 경우는 병원에 늦게 온 경우이며 17례(5%)였다. 이중 합병증이 발생한 경우는 11례로 미란이 7례, 궤양소견을 보인 1례, 출혈 2례, 천공 소견을 보인 1례가 있었다. 4) 동반 질환 : 동반된 질환아 있었던 8례(7.5%)였으며 식도 협착이 5례, 뇌성 마비가 3례였다. 결 론 : 본 병원에 소아 내시경실이 생긴 이후 과거 10년 동안 소아 내시경에 의한 이물의 제거가 많이 이루어졌지만 뚜렷한 이점을 발견 할 수 없었던 강직형 내시경을 이용한 이물의 제거가 최근 2-3년 전까지도 활발히 이루어져 왔다는 것을 알 수 있었다. 유연형 내시경은 전신 마취의 불편함 없이도 쉽게 할 수 있는 안전하고 효과적인 방법이며, 최근 2-3년 간 유연형 내시경에 의한 식도 이물의 제거가 빈번해졌다. 앞으로도 내시경의 발달과 그 보조 기구의 발달로 인하여 전신 마취 없이 유연형 내시경을 사용한 이물의 제거는 활발히 이루어져야 할 것이고 처음에 시도하는 치료 방법으로 선택되어져야 할 것이다.

The aim of this study is to investigate anti-stress effect of Scutellaria baicalensis(SB). The experiments were performed with the use of young (9 weeks of age) male rats of SD strain and the male ICR mice (20-25 g) at the time of first treatment with SB. Animals of the normal group were not exposed to any stress and the control group were exposed to stress. The rats of the Ginseng, Diazepam(BZ) and SB supplementary group were orally administered once a day 100 mg of red ginseng extract, 5 mg of BZ or 100 mg of SB extract/kg body weight and they were exposed to stress. The mice of the Ginseng, BZ and SB supplementary group were given water containing 200 mg of red ginseng extract, 10 mg of BZ or SB extract/100 ml potable water and exposed to stress. Animals were given supplements for 7 days without stress, and then were given supplement for 5 days with restraining and electroshock stress. We recorded stress related behavioral changes of the experimental animals by stressing them using the Etho-vision system and measured levels of blood corticosterone and IL-2. SB supplementation partially blocked the stress effect on locomotion in the rats and mice, and also partially blocked stress-induced behavioral changes such as freezing, burrowing, grooming, smelling, and rearing behavior in the rats and smelling, grooming, tailing, and rearing in the mice. in elevated plus maze test, the staying time of the stressed rats and mice in the open area decreased while it increased in the closed area. But these changes also partially were blocked by SB-supplementation. SB-supplementation decreased levels of the blood corticosterone which was increased by stress in the rats but did not significantly increase levels of blood interleukin 2 which was decreased by stress in mice.

괴각 추출물의 항불안 효능을 탐색하기 위하여 elevated plus-maze, horizontal wire test 및 open field test와 같은 동물행동실험을 통하여 비교한 결과 다음과 같은 결론을 얻었다. Elevated plus-maze를 이용한 본 연구에서 괴각 추출물의 100 mg/kg, 200 mg/kg 및 400 mg/kg 투여군에서 대조군에 비하여 open arm에서 머무른 시간의 백분율이 증가하였고, open arm으로의 출입 백분율 또한 증가하였다. Elevated plus-maze를 이용한 길항실험에서는 benzodiazepine 수용체의 antagonist인 flumazenil에 의해 괴각 추출물 400 mg/kg의 항불안 효능이 차단되는 것이 관찰되었다. Locomotor activity 측정에서도 괴각 추출물의 모든 용량에서 총 이동거리의 변화가 없었으며, 또한 horizontal wire test에서도 대조군과 괴각 추출물 투여군 사이에 차이를 나타내지 않았다. 결론적으로, 본 연구의 결과에서 괴각의 메탄올 추출물이 elevated plus-maze test, horizontal wire test 및 open field test를 통하여 locomotor activity 및 근육이완이나 진정 등의 부작용이 없으면서 우수한 항불안 작용을 가지는 천연물이라고 생각되어지며 이러한 작용이 특히 GABA 신경계와 관련이 있음을 시사하고 있다. 향후 괴각의 항불안 작용의 평가를 위하여 다양한 실험모델의 개발이 필요할 것으로 생각되며 또한 이러한 작용에 대한 기전 연구가 포괄적이고 다각적으로 진행되어져야 할 필요성이 있다고 사료된다.

Even though driving under the influence of drug (DUID) is a worldwide problem, we, Korea has no regulation system yet except for alcohol, and there are little cases reported related to DUID. In order to investigate the type of abused drugs for drivers in Korea, we tried to analyze controlled and non-controlled drugs in alcohol-positive blood samples. 275 whole bloods, which were positive for alcohol on the roadside test, were collected from the police for two months ($Nov.{\sim}Dec.$ 2006). The analytical strategy was constituted of three steps: First, alcohol in blood samples were confirmed and quantified by gas chromatography. Second, controlled drugs were screened by $Evidence_{investigator}\;^{TM}$ (Randox, U.K.) as preliminary test. It was based on immunoassay by biochip array analyzer. Nine groups of drug abuse were screened: amphetamines, methamphetamines, cannabis, cocaine, opiates, barbiturates, methadone, benzodiazepines I (oxazepam) & II (lorazepam). Finally, confirmation of these drugs was performed by GC-MS. Blood samples were extracted by solid-phase extraction by $RapidTrace^{TM}$ (Zymark, U.S.A.). After trimethylsilyl (TMS) derivatization, eluates were analyzed to GC-MS. Total 49 drugs were investigated in this study including controlled drugs, antidepressants, 1st generation antihistamines, dextromethorphan, nalbuphine, ketamine, etc. For rapid detection, we developed the automated identification system. It was made up a new software, "DrugMan", modified Chemstation data analysis menu and newly developed macro modules. A series of peak selection, identification and reporting of the results were performed automatically by this system. Concentrations of alcohol in 275 blood samples were ranged from 0.011 to 0.249% (average, 0.119%). Among 149 blood samples, just six samples (4.0%) were showed positive results to the immunoassay: one methamphetamine and five benzodiazepines group I. By GC-MS confirmation, only benzodiazepines were detected and methamphetamine was not detected from immunoassay positive blood sample. Besides these drugs, 5 chlorpheniramines, dextromethorphan, diazepam, doxylamine, ibuprofen, lidocaine and topiramate were also detected in whole bloods by GC-MS. Conclusively, the frequency of drug abuse for Korean drivers was relatively low. There was none case which illegal drug was detected. However these results were limited to alcohol positive blood samples, so it is necessary to analyze more samples including alcohol negative blood.

Pyroligneous liquid(PL) is produced by carbonizing Oak in 350-40$0^{\circ}C$. It is traditionally used for treating stress-related disorder, hepatic disease, immune disorder, G-I disorder and inflammatory disease. The aim of this study is to investigate anti-stress effects of PL. The experiments were performed with the use of young(9 weeks of age) male rats of SD strain and the male ICR mice (20-25 g). Animals of the normal group were not exposed to any stress and the control group were exposed to stress. The rats of the Ginseng, diazepam(BZ) and PL supplementary group were orally administered once a day 100 g of Ginseng extract-kg body weight, 5 mg of BZ/kg body weight and 1 ml of PL100 g body weight and then exposed to stress. The mice of the Ginseng, BZ and PL supplementary group were given water containing 100 g of Ginseng extract/100 ml potable water, 5 mg of BZ/kg 100 ml of drinking water and 10 ml of PL/100 ml of drinking water and exposed to stress. Animals were given materials for 7 days after stabilizing them, and then were given supplementary materials for 5 days with stress. They were stressed by immobilization for 30 minutes and then the animals were exposed to electroshocks for 5 minutes. We recorded stress-related behavioral changes of experimental animals by stressing them using the Etho-vision system and measured the levels of corticosterone in blood While stress suppressed locomotor activity of animals, PL-supplementation partially blocked the stress effect of locomotion in rats and mice, and also partially blocked stress-induced behavioral changes such as freezing, burrowing, smelling and rearing activity in rats and freezing, grooming, tailing and rearing in mice. The staying time of stressed rats and mice in open area decreased and in closed area it increased relatively in elevated plus maze test. However, these changes also partially were blocked by PL-supplementation. PL-supplementation decreased levels of blood corticosterone increased by stress in rats. These results suggest that PL protects partially the living organism from stress attack in some cases.

Background: Conscious sedation is a useful adjunct in the treatment of patients in dentistry; however, a lack of knowledge among the dental profession regarding sedation is a restricting factor in the practice of dental sedation. Therefore, this study was conducted to assess the knowledge and practice of sedation in dentistry among dental professionals in Tanzania. Methods: This was a cross-sectional study conducted for five months targeting all practicing dental professionals in Tanzania. A modified questionnaire contained 14 questions regarding knowledge about sedative agents and a section on the practice of sedation. The data obtained from this study were coded and entered into a computer program and analyzed using SPSS software version 23.0. The data are presented as frequencies and percentages in tables and charts. Statistical significance was set at P < 0.05. Results: The age range of participants was between 24 and 63 years (mean 36.6 ± 7.7 years). There were 107 men (78.1%), and the male-to-female ratio was 3.6:1. The majority (76.6%) of participants only had an undergraduate dental degree. Thirty-one percent of participants only worked in publicly owned health facilities. Slightly more than half (59.9%) of participants had satisfactory knowledge regarding sedation in dentistry. There was no statistically significant association between the level of sedation-related knowledge and the demographic characteristics of the participants. Only 21.9% reported using sedation in their practice, and the most commonly used sedative drug was diazepam. The reasons for not using dental sedation in clinical practice included a perceived lack of knowledge on sedation, lack of equipment, and cost. Conclusion: Most dental professionals in Tanzania have basic knowledge of sedation in dentistry, although knowledge regarding sedative agents is generally low. The practice of sedation in dentistry in Tanzania is very low compared to that in middle- and high-income countries. Inadequate knowledge, lack of equipment, and the cost of practicing sedation are the main reasons for not practicing sedation.

목적: 본 연구의 목적은 섬망이 있는 말기암환자에 있어 진정제의 투약 투약 관련 특성을 파악하고, 진정제 투약군과 비투약군 간의 생존기간의 차이를 확인하기 위함이다. 방법: 본 연구는 2012년 1월부터 2013년 12월까지 B 광역시 소재 P대학교병원에서 응급실과 수술실, 중환자실을 제외한 병동에서 임종한 암환자 900명 중 경과기록지, 간호기록지를 통해 섬망선별 도구인 Nu-DESC를 이용하여 섬망이 있었던 말기암환자 240명을 대상자로 선정하였다. 투약기록지를 통해 진정제인 haloperidol, diazepam, lorazepam을 정맥 또는 근육주사로 규칙적이거나 필요 시 투여한 횟수를 조사하였다. 결과: 연구 대상자의 섬망기간은 최소 1일에서 최대 61일까지 나타났고, 중앙값은 5일이었다. 연구 대상자에게서 나타난 섬망 특성은 부적절한 행동이 35.0%로 가장 많았다. 연구 대상자의 연령(F=3.96, P=0.021), 원발암의 종류(F=3.31, P=0.010), 항암치료 여부(t=-3.44, P=0.001)에 따른 섬망기간이 유의한 차이가 있었다. 연구 대상자가 진정제를 복용한 경우는 72.1%이었고, 투약된 진정제의 종류는 haloperidol이 59.6%로 가장 많았다. 진정제 투약군의 생존기간은 평균 16.85일, 비투약군은 9.37일로 나타났으나 이는 통계적으로 유의하지는 않아(t=1.766, P=0.079) 진정제 투약이 생존기간에 영향을 미치지는 않았다. 결론: 말기암환자의 섬망 발생 시 진정제 투약이 생존기간에 미치지 않았다. 이러한 결과를 바탕으로 생명단축의 윤리적 문제로 인해 진정제 사용을 꺼려하기 보다는 증상완화를 위한 진정제 치료를 적극적으로 권유할 수 있다. 또한 섬망은 가족이나 의료진과의 의사소통 장애를 유발할 뿐 아니라 환자나 가족들에게 스트레스로 작용하며 돌봄에 대한 부담감을 가중시키므로, 적절한 진정제의 투여는 말기암환자와 가족의 안위를 위해 적극적으로 추천하는 바이다.
