The study was conducted to evaluate the difference of life style, subjective symptoms and health cognition depending on the Sasang Constitution in the industrial workers. The results were as follows ; Constitutional distribution among exposed group were Tae-eum In(38.4%), So-eum In(35.2%), and So-yang In(26.4%) and it was turned out that Tae-eum In took a higher portion of Sasang constitution than other constitutions in technician workers. 'Exercise' and 'Obesity' were found most in Tae-eum In, In So-eum In there were many 'Normal' weight and 'Having digestive disorders' were found most in So-eum In. There were no significant difference in the health cognition among the constitutions. The closer to 'normal' weight, the higher prevalence in 'having' concern about health condition and the more 'normal' condition in sleeping, the higher prevalence of 'having' self-confident in present health.

소금영,양인호,안태훈,이준영 朝鮮大學校 附設 醫學硏究所 2006 The Medical Journal of Chosun University Vol.31 No.2

Background: Although lidocaine seems to be one of the most suitable spinal anesthesias for ambulatory surgery, the safety of lidocaine spinal anesthesia has been called into question by report of both permanent and transient neurologic toxicity. The purpose of this study is to investigate the possibility of adapting the longer acting spinal bupivacaine in short duration of lower extremity operation. Methods: Forty five patient were randomly assigned to three groups for spinal anesthesia, Group Ⅰ (15㎎ bupivacaine), 3㎖ of 0.5% spinal bupivacaine in 8% dextrose; Group Ⅱ (10㎎ bupivacaine), 2㎖ of the 0.5% spinal bupivacaine +1㎖ saline; Group Ⅲ (7.5㎎ bupivacaine), 1.5㎖ of the 0.5% spinal bupivacaine +1.5㎖ saline. Dural puncture were performed at the L3-L4 with 25 gauge needle in lateral position after which the patients were turned to the supine horizontal position. We checked peak sensory level and height, time to two segment regression and S2 sensory regression via pin-prick test and motor block level by modified Bromage scale. Results: There were significantly difference with regard to peak sensory level and height, time to two segment regression and S2 regression, and motor blockade level between Group Ⅰ, Ⅱ and Group Ⅲ. Conclusions: Dilute Bupivacaine in spinal anesthesia provided the combination of adequate depth of anesthesia and rapid recovery. We conclude that 0.5% bupivacaine 7.5㎎ with normal saline 1.5㎖ is effective in spinal anesthesia for short-duration lower extremity surgery.

The zebrafish (Danio rerio) is now the prominent vertebrate model system for clarification of the roles of specific genes and signaling pathways in development. Zebrafish embryos provide many advantages for experimental and genetic analysis of vascular development. In this study we describe the use of zebrafish model system for the experimental study of angiogenesis. We established several technical methods to define cellular and molecular alterations in vascular development; whole-mount in situ hybridization, microangiography, and alkaline phosphatase staining. We also introduced the overexpression experiments by using in vitro-transcribed synthetic mRNAs and vascular-specific gene promoters. For the gene knock-down analyses, we challenged morpholino antisense oligonucleotide system. With these efforts, the zebrafish might be used as a powerful tool for the screening of effective angiogenic factors.

The soil microarthropods' fauna, population density, vertical distribution, seasonal fluctuation and the relationship between the number of soil microarthropods and environmental factors were studied. Samples were taken bimonthly from April to October, 1984 from uncultivated area; a forest, and as well as diversely cultivated areas such as an orchard, a cultivated upland, a ginseng field, and a horticultural field in Chon Buk province, Korea. The results were summarized as follows: 1. Soil microarthropods community included Acarina (47.9%), Insecta (50.4%), Chilopoda, Symphyla, and Diplopoda etc. 2. Acarina consisted of Cryptostigmata (80.3%), Mesostigmata (13.5%), Prostigmata (3.9%) and others. 3. Insecta composed of 7 orders such as Collembola(66.9%), Hymenoptera(23.9%), Diptera(6.6%) Thysanoptera, Colleoptera, Protura, and Psocoptera. 4. Cryptostigmata in Acarina recorded 24 families, 37 genera and 60 species, of which 5 species, namely Tectocepheus velatus, Oppia tokyoensis, O. sp,. Schelorivates latipes, S. laevigatus were found at all sampling areas and of which 14 species, namely Archoplophora, Eohypochthonius crssisetiger, Hypochthoniella minutisima, Lohmannia sp., Hypochthonius sp., Epilohmannia ovata, E. sp., Nothrus biciliatus, Camisia lapponica, C. sp., Malaconothrus japonicus, M. sp., Allodamaeus sp., Microzetes auxiliaris etc., were found at one sampling area. 5. Diversity index; number of species/number of individuals (S/√N) was higher in cultivated areas than in uncultivated sampling areas. There was more species variety with a small number of individuals in uncultivated area than that of cultivated area, but less species variety with a larger number of individuals in cultivated areas owing to more distructive factors in cultivated areas.

척수강내 Bupivavacain에 첨가한 소량의 Neostigmin의 진통효과와 부작용

소금영,정종달,김병철,유벙식,안태훈,김훈정,임경준 조선대학교 2000 The Medical Journal of Chosun University Vol.25 No.2

Background : Spinal cholinergic receptor has been shown to have a antinociceptive action, an effect that can be mimicked by spinal cholinesterase inhibitor. Intrathecal injection of neostigmine cause analgesia and adverse effect in a dose-dependent pattern in the patients. The purpose of this study was to determine whether small doses of intrathecal neostigmine (10, 25 and 50 ㎍) produce analgesia and any side effects. Method : After getting informed consents, 60 patients scheduled for orthopedic surgery of lower extremities under spinal anesthesia were randomly assigned to one of four groups. Using dose-ranging design, patients received either normal saline or neostigmine l0, 25 or 50 ㎍ in a 1-㎎ solution of 5% glucose in normal saline with heavy bupivacaine 12 ㎎. Heart rate, blood pressure, degree of motor and sensory block were recorded. The assessment of postoperative analgesia included time to first rescue, total number of rescue medication and pain score on visual analog scale (VAS) at 1, 3, 6, 9, 12, 24 hour. Nausea and vomiting were assessed by using the visual analog scale at 24 hr postperatively and the incidence of them was recorded postoperatively. Result : There were no significant differences among the four groups in characteristics of spinal blocks. Compared to saline, neostigmine groups significantly prolonged time to first rescue medication and decreased total number of rescue medication and pain visual analog scale score, but incidence of nausea and 24hr nausea VAS score were not increased in neostigmine group compared to control group. Conclusion : These data in patients injected intrathecal neostigmine suggest that analgesia may occur at doses less than neostigmine 50 ㎍ and neostigmine 50㎍ has a better analgesia effect with fewer side effects than other doses for postoperative analgesia.

소금영,식홍림,임시경,안태훈,임태승 朝鮮大學校 附設 醫學硏究所 2004 The Medical Journal of Chosun University Vol.29 No.3

Background: Pain is major problem regarding quality of life in children undergoing tonsillectomy. Preemptive analgesia by medicine given before commencement of surgery is a new recommended for relief of pain during and after operation. We compared intra-and postoperative analgesic and recovery characteristics of tramadol, meperidine given at induction of anesthesia in 40 ASA I or II children undergoing tonsillectomy with or without adenoidectomy. Materias and Methods: Fourty children aged 4-7 years undergoing tonsillectomy with or without adenoidectomy were randomly assigned to receive either tramadol 2 mg/kg (group 1) or meperidine 1 mg/kg (group 2) at induction of anesthesia. Thiopental sodium (5 mg/kg) and rocuronium (0.6 mg/kg) were used for the induction of anesthesia, and it was maintained with sevoflurane in N₂O/O₂50/50 via an endotracheal tube. Pain assessment was done by facial pain scale. Agitation scores, time to recovery of spontaneous respiration and the incidence of postoperative nausea and vomiting. Heart rate and mean arterial pressure was recorded at regular intervals. Results: Facial pain scale scores were increased in group 1 at 10 and 20 min in recovery room. There was no difference for agitation scores in the two groups. Intraoperative mean arterial pressure (15th min) were found to be higher in group 1. The time to recovery of spontaneous respiration was delayed with group 2 compared with group 1. The incidence of nausea and vomiting was not statistically differed between groups. Conclusions: Meperidine was more effective for pain relief than tramadol after tonsillectomy in children.
