흡입물질의 위생학적 연구 : 본드 흡입이 흰쥐의 폐 및 기타 장기의 효소 활성에 미치는 영향 The Effect of Bond Inhalation on the Enzyme Activity of Lung and Other Organs in Rat

윤수홍,박은주,이주영,서혜령 효성여자대학교 부설 한국환경위생연구소 1991 환경위생연구 Vol.1 No.1

Toluene, alcohol및 vinylester류 등을 함유하고 있는 bond를 이용하여 휘발성 물질이 생체에미치는 영향을 관찰하기 위하여 rat에 일정 농도의 bond를 일정 시간 흡입시킨 뒤 각 조직에대하여 효소의 생화학적 시험과 celluloseacetate electrophoresis를 실시하여 다음과 같은 결과를얻었다. 1. Bond 흡입은 시간이 증가함에 따라 혈청, 심장, 신장, 근육, 뇌의 ChE 활성을 억제하였으며특히 폐와 간장의 ChE활성에 가장 큰 영향을 나타내었다. 2. Bond 흡입에 의해 혈청 및 각 조직 중에서 LDH활성이 증가되었으며 특히 폐와 심장,근육에서 그 영향이 현저히 나타났다. 3. Celluloseacetate electrophoresis를 통한 각 조직의 LDH isozyme pattern에는 차이가 나타났으며 bond 흡입에 의해 band의 소멸과 선명도의 감소가 일어 났는데 특히 폐에 대한 독성이가장 현저했으며 근육에 대한 독성도 큰 것으로 나타났다. Acute poisoning with organic solvents and other volatile compou-nds now usually follows deliberate inhalation(volatile substance abuse) or inges-tion of these compounds. The effect of bond inhalation was analyzed for serum, liver, lung, brain,heart, kidney and muscle. And the observations are revealed on rat cholinesterase activity, lactatedeh-ydrogenase activity and electrophoretic pattern of lactatedehydrogenase isozyme. The results are as follows ; 1. The rat cholinesterase activity on serum, heart, muscle, kidney and brain showthe decrease by increasing of inhalation time of bond, in particular the lungand liver cholinesterase activity was greatly affected. 2. Bond inhalation brough out the lactatedehydrogenase activity increased ofthe serum and the tissues and had an important effect especially in both thelung and muscle lactatedehydrogenase activities. 3. Each tissue was found to have a characteristic distribution of lactatedehydro-genase isozymes on celluloseacetate elelctrophoresis and the development ofinhalation time is shown the disappearence and diffusion of band.

교정용 미니 임플랜트 고정원과 SWA en masse sliding retraction 시 전치부 치축 조절 요인에 관한 유한요소해석

정혜심,성상진,문윤식,조영수,임승민 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.5

교정용 미니 임플랜트 고정원을 이용한 교정 치료가 보편화되며, SWA와 이를 이용한 en masse sliding retraction은 임상에서 흔히 사용하는 치료법이 되었다. 그러나 고정원을 성공적으로 보존하려는 노력에 비해, 발치 공간 폐쇄 시 전치부 치축 조절에 관여하는 요인에 대한 보고는 아직까지 부족한 실정이다. 본 연구에서는 제1소구치를 제거한 상악 치아와 치주 인대 그리고 치조골에 대한 3차원 유한요소 기준모델을 제작하였고, 제1대구치와 제2소구치 사이 주호선 10 mm 상방에 식립된 교정용 미니 임플랜트를 고정원으로 사용할 경우, 측절치-견치 사이의 견인 훅의 높이를 변화시키며 후상방 견인력을 가하거나, 주호선에 보상 만곡을 부여하는 것이 전치부 치축 조절에 어떤 영향을 미치는지 시뮬레이션 하였다. 또한 전치부 치축이 설측 경사된 모델을 같은 실험 조건으로 시뮬레이션 하여 발치 공간 폐쇄 시 설측 경사된 전치부 치축을 유지하거나 개선할 수 있는 요인을 검토하였고, 다음과 같은 연구 결과를 얻었다. 2 mm 높이의 견인 훅에 대하여 후상방으로 견인력을 가할 경우 발생하는 함입력으로 인하여 전치부 설측 경사가 더 감소되지는 않았다. 견인 훅의 높이가 5 mm인 경우 후상방 견인력을 가하면, 측절치의 치관 순측 및 치근 설측 이동이 일어나고, 견치의 비조절성 후방 경사 이동이 심화되었다. 4 mm의 보상 만곡은 측절치의 치관 순측 및 치근 설측 이동을 일으키고, 견치의 비조절성 후방 경사 이동을 감소시켰다. 또한 전치부가 설측 경사된 모델을 기준모델과 같은 실험 조건으로 시뮬레이션 한 경우 치근면의 응력 분포와 25000배 확대된 그래프 상에서의 치아 이동 양상은 매우 유사하였다. 이상의 결과는 미니 임플랜트-SWA sliding 생역학을 구사 시 견인 훅의 위치와 와이어 상의 보상 만곡의 유무에 의해 전치부의 치축 조절이 달라지며 실제 임상에서 가이드라인으로 활용될 수 있을 것이다. Objective: With development of the skeletal anchorage system, orthodontic mini-implant (OMI) assisted en masse sliding retraction has become part of general orthodontic treatment. But compared to the emphasis on successful anchorage preparation, the control of anterior teeth axis has not been emphasized enough. Methods: A 3-D finite element Base model of maxillary dental arch and a Lingual tipping model with lingually inclined anterior teeth were constructed. To evaluate factors influencing the axis of anterior teeth when OMI was used as anchorage, models were simulated with 2 mm or 5 mm retraction hooks and/or by the addition of 4 mm of compensating curve (CC) on the main archwire. The stress distribution on the roots and a 25000 times enlarged axis graph were evaluated. Results: Intrusive component of retraction force directed postero-superiorly from the 2 mm height hook did not reduce the lingual tipping of anterior teeth. When hook height was increased to 5 mm, lateral incisor showed crown-labial and root-lingual torque and uncontrolled tipping of the canine was increased. 4 mm of CC added to the main archwire also induced crown-labial and root-lingual torque of the lateral incisor but uncontrolled tipping of the canine was decreased. Lingual tipping model showed very similar results compared with the Base model. Conclusion: The results of this study showed that height of the hook and compensating curve on the main archwire can influence the axis of anterior teeth. These data can be used as guidelines for clinical application.

This study was designed to exam the aged's needs for spiritual nursing care. The purpose was to serve as a basis for the development of spiritual nursing practice. The major findings are as follows : 1. The degree of needs for spiritual nursing care as area was that needs of love and relationship mean 22.0, needs of meaning and object mean 28.2, needs of forgiving mean 13.5. Total needs for spiritual nursing care mean 63.7, which was on the upper middle level. The needs of meaning and object was rated highest. 2. Among the general characteristics of the subjects, needs of love and relatiohship wasn't significanlty different. 3. Among the general characteristics of the subjects, needs of meaning and object was significantly different according to two factors : age(F=7.260, p=0.001), religion(F=5.275, p=0.001). Higher needs of meaning and object was possessed by the older than the younger, by the one who have religion than the other. 4. Among the general characteristics of the subjects, four factors made a significantly difference to needs of forgiving : sex(t=-2.851, p=0.006), age(F=8.201, p=0.001), religion(F=6.928, p=0.000), disease(t=2.327, p=0.024). Higher needs of forgiving was possessed by man than woman, by the older than the younger, by the one who have religion than the other, by the one who have disease than the other.

Malignant struma ovarii is a rarely reported disease and the diagnostic criteria is still in debate. A 43 years old woman admitted to our hospital because of palpable lower abdominal mass in 1993. On ultrasonography, a cystic mass, measuring 6.1cm in long diameter, was found in the left ovary, and laparoscopic left salpingo-oophorectomy was performed. Submitted left ovarian tissue consisted of multiple fragments, and focal yellowish brown nodules were seen along the inner side of the cystic mass. Microscopically, mature cystic teratoma with focal thyroid tissues exhibiting usual nodular hyperplasia of thyroid gland or follicular adenoma of fetal type and positive reaction for thyroglobulin was observed. Neither cytologic atypia of follicular cells nor mitosis were found in the thyroid tissue, but thyroid tissue showed focal infiltrative borders into ovarian stroma and evidence of vascular invasion. The thyroid function test was within normal limit, and no abnormal finding was noted on thyroid scan at that time. In 2002, TAH with right salpingo-oophorectomy was done because of hypermenorrhea and palpable lower abdominal mass. A cystic mass and multiple small yellowish brown nodular lesions were found along the serosal surface of the uterus. Microscopically findings suggesting papillary carcinoma of thyroid gland, follicular variant, were noted. In 2003, segmental resection of small intestine and rectum were performed, and nodular lesion involving the rectal wall showed features suggesting follicular carcinoma of thyroid gland. We report a case of malignant struma ovarii recurred in the pelvic cavity, 9 years after left oophorectomy.

Ohjective : The primary purpose of this study was a replication of the effectiveness and tolerability of rispehdone in the treatment of patients with acute mania in very larger cohon in naturalistic treatment setting to extend the data on the effect and tolerability of risperidone in the treatment of patients with acute mania to Asian population. Methods : A total of 909 patients with DSM-TV criteria of bipolar disorder current manic and hypomanic episode, entered this large, open, multicentre study. The Young Mania Rating Scale (YMRS), Clinical Global Impression (CGI) and Simpson-Angus Rating Scale (SARS) were measured at baseline and weeks 1, 3 and 6, for the assessment of effectiveness and extra-pyramidal symptom (EPS). Results : This study showed statistically significant reduction of scores on the YMRS and CGI-s (mean change=-23.5±11.8, p<0.0001 ; mean change=-2.7±1.5, p<0.0001, respectively) from the baseline to the endpoint (week 6). Number of patients with 50% reduction or more in the YMRS and CGI-s scores was 693 (77.8%) and 630 (70.7%) at endpoint, respec-tively. There were no statistically significant increments of scores on SARS. Risperidone was generally well tolerated. Conclusion : The present larger open study demonstrates that hsperidone add-on therapy is effective and tolerable in treat-ment of bipolar disorder, replicating results in various controlled and uncontrolled studies from Western countries.
