The purpose of this study is to investigate the differences of personality characteristics using Minnesota Multiphasic Personality Inventory(MMPI) by current-smokers, ex-smokers and non-smokers among male high school students. The subjects for this study were 448 first and second year male students at general and vocational high school in Taegu and Kyung-Buk Province. Data was collected from August 25 to September 15, 1999. The instrument used in this study was the Validity Scale and the Clinical Scale, the Ego Strength Scale and the Personality Disorder Scale of the MMPI. The data was analysed by using the SPSS Program which included frequency, percentage, x^2-test, ANOVA, scheffe test and stepwise discriminant analysis. The results obtained from this study were as follows. (1) There were significant differences by smoking behavior groups in parents who smoke and who did not smoke(p=.044), intimate-friends who smoke and not(p=.000), academic record(p=.000), satisfaction with school life(p=.020), effect of smoking on health(p=.000), drinking experience(p=.000), drug-use experience(p=.007) and experience into No minors district(p=.000). (2) T-scores of subjects in this study were in the range of 40-60. Psychopathic Deviate Scale(Pd), Paranoid Scale(Pa), Psychasthenia Scale(Pt), Schizophrenia Scale(Sc), Histrionic Personality Disorder Scale(HST) and Anti-social Personality Disorder Scale(ANT) showed higher T-scores than other Clinical and Personality Disorder Scale. (3) The results of post-hoc in Validity Scale and Clinical Scale are as follows: T-scores of current-smokers were higher than that of ex-smokers and non-smokers in Hysteria Scale(Hy), Psychopathic Deviate Scale(Pd), Paranoid Scale(Pa), Psychasthenia Scale(Pt), Schizophrenia Scale(Sc) and Hypomania Scale(Ma); T-scores of non-smokers were higher than that of ex-smokers in Depression Scale(D), and T-scores of non-smokers were higher than that of current-smokers and ex-smokers in Social Introversion Scale(Si). (4) In Ego Strength Scale and Personality Disorder Scale, T-scores of ex-smokers were higher than those of current-smokers. In Histrionic Personality Disorder Scale(HST) and Narcissistic Personality Disorder Scale(NAR), T-scores of current smokers and ex-smokers were higher than those of non-smokers. In Borderline Personality Disorder Scale(BDL), Anti-social Personality Disorder Scale(ANT) and Paranoid Personality Disorder Scale(PAR), T-scores of current-smokers were higher than those of ex-smokers and non-smokers. In Schizotypal Personality Disorder Scale(STY), T-scores of current smokers were higher than that of ex-smokers. In Avoidant Personality Disorder Scale(AVD), T-scores of non-smokers were higher than those of current-smokers and ex-smokers. (5) As a result of stepwise discriminant analysis of the MMPI Scale by smoking behavior, a discrimination rate of the F Scale, Hypomania Scale(Ma), Social Introversion Scale(Si) and Psychopathic Deviate Scale(Pd) out of the Validity Scale and Clinical Scale was 51.1%, and that of Anti-social Personality Disorder Scale(ANT) and Avoidant Personality Disorder Scale(AVD) out of the Personality Disorder Scale was 51.6%, both of the rates were statistically significant. The Above results suggested that smoking by high school students is related with personality characteristics as well as external factors like family, school and their social environment. So school health professionals who are in charge of school health, should operate various smoking prevention or prohibition programs, taking into account personality characteristics. It might have an effect on smoking prevention and the reduction of the smoking rate.

본 연구는 생화학적 검사에 의한 철 영양상태의 판정시 검사항목에 따른 판정의 정확도를 보기 위하여 외견상 건강한 18!21세의 여대생 57명을 대상으로 혈액성분 중 Hb, Hct, serum ferritin을 측정하고 그 상관성을 분석하였다. 1) 조사대상자의 Hb는 평균이 13.9±0.96g/dl, 중앙값이 14.2g/dl였다. Hct의 평균은 41.4±2.85%, 중앙값은 42.0%였고,ferritin은 평균 20.7±15.5ng/ml, 중앙값 16.5ng/ml,최빈값 3.40ng/ml였다. Hb, Hct, ferritin값 모두 Kolmogorov-Smirnov test결과 정규분포 하는 것으로 나타났다. 2) Hb와 Hct간에는 r=0.9467(p<0.001)로 <Hct=2.28+2.81×Hb>의 회귀관계를 보였다. Hb와 ferritin간에 r=0.5591((P<0.001)로 <log(ferritin)= -1.73+0.07×Hct>의 회귀식이 구해졌다. 3) 빈혈발현율은 Hb 12g/dl를 기준시 5.3%, Hct 36% 기준시 10.5%, ferritin 12ng/ml 기준시 36.8%였다. 4) fFerritin함량을 기준하여 Hb, Hct판정에 대한 신뢰도를 분석한 결과, 빈혈 판정시 많이 이용되는 Hb 12g/dl 미만이나 Hct 36% 이하를 기준했을 때 두 방법 모두 sensitivity가 매우 낮았으며 specificity는 매우 높은 값을 보여, 빈혈 발현율이 높은 우리나라의 경우 Hb나 Hct의 판정기준치를 높일 필요가 있는 것으로 나타났다. 5) 빈혈 판정을 위한 검사방법으로서의 Hb측정은 sensitivity, specificity등을 고려할 때 판정 기준치를 14g/dl로 하는 것이 타당할 것으로 보인다. Hct의 경우 판정치를 40%로 높일 경우에 false-negative rate가 42.9로 낮아졌다. The iron status of 57female college students was evaluated by measurements of hemoglobin(Hb). hematocrit(Hct) and serum ferritin(Ferritin). Mean values for Hb. Hct and Ferritin were 13.9±0.96g/dl. 41.4±2.85% and 20.7±15.5ng/ml. respectively. Ferritin as well as Hb. Hct were not statistically different from normal distribution. although ferritin were skewed to the right. The prevalence of anemia defined by Hb<12g/dl. Hct≤36% and Ferritin<12ng/ml were found to be 5.3,10.3 and 36.8%. respectively. By using Hb as a screening tool at a cutoff point fo 12g/dl. 2.8% of healthy subjects will be incorrectly classified as anemic and 90.5% of anemic as healthy. Sensitivity and specificity were calculated at various cutoff points of Hb and Hct. The estimates of sensitivity and specificity allow Hb 14.0g/dl as cutoff point for good predictor of anemia.

상악매복견치의 진단 및 처치

경승현,황충주 대한치과교정학회 1993 대한치과교정학회지 Vol.23 No.2

치열궁에서 전치부와 구치부를 연결하며 치근이 가장 긴 치아인 견치는 악궁에서 cor-ner stone이라고 불릴 만큼 치열궁의 형태나 유지, 안모의 심미성에 많은 영향을 미치는 치아중의 하나이다. 여러 부위의 견치중 상악견치는 periodontium의 periodontal fiber로 교합을 유도함으로써 치열궁의 보호와 안정성에 중요한 역할을 담당한다. 상악 견치는 대구치와 거의 같은 시기에 석회화가 시작되나 제1대구치는 6세에 맹출되고 견치는11~13세에 맹출하게 되므로 견치는 발육기간이 어느 치아보다 길며 이러한 장기간의 발육, 매우 곡절된(tortuous) 맹출경로, 인접치아중 가장 늦은 맹출시기 등으로 인하여 견치자체나 그 인접조직에 약간의 이상이 있더라도 final position에 영향을 받게 되고 매복도 쉽게 일어난다. 제3대구치를 제외하고 가장 빈번한 매복율을 나타내며 매복시는 매복으로 끝나는 것이 아니라 악궁의 정중선의 변이,악구의 수축과 같은 복잡한 부정교합을 야기하며, 전이 동통, 치성낭종, 인접치아의 흡수뿐 아니라 안모의 변화와 같은 심미성에도 영향을 미치게 된다(Fig.1). 상악 견치의 매복을 방지하거나,매복시 즉각적이고 올바른 진단과 치료를 한다면 건강하고 정상적인 견치로 적절한 교합을 이를 수 있으므로 견치가 매복되었을 때 진단에서 부터 보정까지 세심한 주의를 기울여 정상적인 기능을 하는 견치를 얻도록 해야한다. 이를 위하여 상악 견치 매복의 주요원인, 진단방법 그리고 처치방법등에 관하여 알아보고자 한다. Upper canine is important because it protects and maintains the stability of the dental arch and also, joins the anterior with the posterior teeth. The incidence of impaction of upper canine is the second most frequent next to the third molar because it takes a long period of time to develop, and has a complicated path of eruption, and erupts lately. After the age of 10, clinical and radioglaphic examination can be used in revealing the possibility of impaction and efforts should be put to reduce the side effects. To prevent impaction, selective extraction of primary canine at the age of 8 to 9 could be considered and prolonged retention of primary canine in oral cavity should be avoided at this time. Once the impaction is iden, the first stage of the treatment is to lcocalize the lesion by radiographic examination and According to the severity, orthodontic traction or autotranxplantation should be considered and comprehensive diagnosis and treatment plan of malocclusion should be established. Generally, labial impaction is due to arch length discrepancy and palatal impaction is due to malposition or morphologic pathosis of lateral incisors rather than arch length discrepancy. In surgical procedure, peridontal problems should be considered and the minimum amount of bone and soft tissue shold be reduced and direct bonding method of many attachment methods should be recommended. Especially in traction of labially impacted canine, it should be guided to erupt through the keratinized zone and proper forced magnitude should be applied. The importance of periodontal condition should always be in mind following the patient education to mintain the good oral hygiene at each stage of treatment. Properly managed impacted canine can provide function and esthetic by proper diagnosis and treatment if extraction of canine is not indicated.

Nucleophilic additon of allyl magnesium bromide to berberine chloride resulted in the 8-allyl-9, 10-dimethoxy-2, 3-methylenedioxy-13, 13a-dehydroberbine[Ⅰ]. And oxidation of [Ⅰ] with m-chloroperbenzoic acid in a stream of Argon at-20∼-30℃ afforded the 8-allylberberinephenolbetaine [Ⅱ], and cycloaddition of [Ⅱ] with dialkylacetylenedicarboxylate(R; a=CH_3, b=C_2H_5) in THF gave 8-allyl-9, 10-dimethoxy-2, 3-ethylendioxy-13-oxo-8, 14-ethenodimethyldicarboxyberbine[Ⅲ a] and 8-allyl-9, 10-dimethoxy-2, 3-methylenedioxy-13-oxo-8, 14-ethenodiethyl-dicarboxy-berbine[Ⅲb]. Heating of 8, 14-ethenoberbines[Ⅲa and Ⅲb] in ethanol effected smooth isomerization leading to the 3, 4-[benzo(3",4"-dimethoxy)]-1, 8-[dihydre(2',3'-methylenedioxy) naphthalene]-5-allyl-6, 7-dimethylcarboxy-2-oxo-azocine[Ⅳa] and 3, 4-[benzo(3", 4"-dimethoxy)]-1, 8-dihydro(2', 3'-methylenedioxy)naphthalene]-5-allyl-6, 7-diethylcarboxy-2-oxo-azocine[Ⅳb]. Irradiation of berberine chloride in methanol containing rose bengal and sodium methoxide with O_2 stream afforded the 8, 9, 10, 14-tetramethoxy-2, 3-methylenedioxy-13-oxoberberine[Ⅳ], and recrystallization of [Ⅳ] from methanol gave 8-methoxyberberinephenolbetaine[Ⅶ]. And cycloadditon of [Ⅶ] with dimethyl-acetylenedicarboxylate gave 8, 9, 10-trimethoxy-2, 3-methylene-dioxy-13-oxo-8, 14-ethenodimethyldicarboxyberbine[Ⅷ], and heating of [Ⅷ] in ethanol effected smooth isomerization leading to 3, 4-[benzo(3" 4"-dimethoxy)]-1, 8-[dihydro(2',3'-methylene-dioxy) naphthalene]-5-methoxy-6, 7-dimethylcarboxy-2-oxo-azocine[Ⅸ]. The in vitro biological evaluation showed that compounds[Ⅷ] and [Ⅸ] had antibacterial effect against Pseudomonas aeruginosa, and compounds [Ⅰ], [Ⅱ], [Ⅲb] and [Ⅶ] completely had anticancer activity to P-388 mouse lymphocyle leukemia at concentration of 100㎍, and [Ⅰ] almost had anticancer activity at concentration of 20㎍.

토끼 신장 근위세뇨관 일차 배양 세포에서 Bradykinin의 Phospholipase D(PLD)에 의한 신호 전달 기전

정성현,박경협,정지창 慶熙大學校 1993 論文集 Vol.22 No.-

Recently, phospholipase D (PLD) is known to be involved in several bioactive materials-mediated signal transduction pathway. In order to investigate how bradykinin works in renal tissue, we in this study wants to figure out whether bradykinin mediates its physiological actions through activation of PLD or not. Bradykinin, which is a well known neuroactive peptide and plays many important physiological roles as vasodilatation, hyperalgia, has been reported to activate PLD in PC12 cells. As a corollary of our experimental results, we are first group ever to reveal the positive involvement of PLD in bradykinin-mediated signal transduction mechanism in the rabbit kidney proximal tubule cells.

Recent experimental studies and clinical cases have suggested that grafting tissue from the adrenal medulla into the brain may alleviate the symptoms of Parkinson's disease. Autologous adrenal medullary grafts into the striatum was performed stereotactically in two patients with Parkinson's disease. Both patients were bedridden preoperatively, but 4 months after the surgery both became ambulatory and one was even capable of returning to his job. Even though the number of cases was small⑵ and the follow-up period was short, this study shows that adrenal medullary transplantation into the striatum may have some beneficial effects in patient with Parkinson's disease. Further experimental and clinical trials are necessary to see whether this procedure will be a recommendable surgical treatment for patients suffering from Parkinson's disease.

김도현,이진우,차경석,정동화 대한치과교정학회 2009 대한치과교정학회지 Vol.39 No.6

본 연구는 전산화 단층촬영 영상으로 상악동의 형태를 파악하여 교정용 미니스크류를 안전하게 식립할 수 있는 위치를 찾고자 시행되었다. 남자 20명, 여자 20명의 3차원 전산화 단층촬영 사진을 촬영한 후 3차원 영상프로그램을 이용하여 상악동의 형태를 계측하여 통계 분석하였으며 다음과 같은 결과를 얻었다. 상악동저에서 백악법랑경계까지의 골두께는 제1대구치와 제2대구치 사이에서 유의하게 얇았고, 제1소구치와 제2소구치 사이에서 유의하게 두꺼웠다. 상악동저에서 협측 상악골 외연까지의 두께는 제1대구치와 제2대구치에서 유의하게 두꺼웠으며, 제1소구치와 제2소구치 사이에서 유의하게 얇았다. 이상의 결과를 바탕으로 안전하게 미니스크류를 식립하여 교정치료의 영역을 넓힐 수 있을 것이다. Objective: Miniscrews are widely used in orthodontic treatment for the purpose of anchorage control. Maximum anchorage can be acquired by the use of miniscrews. Maxillary miniscrew has many clinical advantage for orthodontic treatment. Maxillary sinus, tooth root can be an obstacle for maxillary miniscrew installation. The purpose of this study was to find the safest area and direction of miniscrew insertion in consideration of the maxillary sinus. Methods: The maxillary sinus area of 40 patients (20 male, 20 female) was measured using 3D computed tomography and 3D reconstruction program. Results: The maxillary sinus floor was located most inferiorly between the 1st molar and 2nd molar and located most superiorly between the 1st premolar and 2nd premolar. Buccal bone thickness from the maxillary sinus is significantly thicker between the 1st molar and 2nd molar and significantly thinner between the 1st premolar and 2nd premolar. The area between the 1st premolar and 2nd premolar has a significantly longer vertical distance from CEJ to sinus in consideration of buccal bone thickness. Conclusions: Considering maxillary bone thickness, the posterior area has advantages over the anterior area for installing miniscrews safely and preventing perforation.
