목적 : H. influenzae는 성인에서 흔히 호흡기 감염을 일으키는 균주로, 최근 ampicillin 내성 β-lactamase 생성 균주들이 지속적인 증가를 보이고 있어, 이에 국내 성인에서 H. influenzae에 의한 감염의 임상양상과 분리된 균주들의 미생물학적 특성을 조사하고자 하였다. 방법 : 1998년 3월부터 1999년 9월까지 고려대 구로병원에 내원한 환자중에서 H. influenzae가 분리된 68명을 대상으로 임상양상을 조사하고 항균제 감수성 검사를 시행하였다. 분리된 33주에 대해서 혈청형, 생물형, 세포외막 단백분석을 시행하였고, β-lactamase 생성여부에 따른 감염 환자군간 임상상 및 예후의 차이를 비교하였다. 결과 : 환자의 평균연령은 68세였고, 지역사회 획득감염이 전체의 85%를 차지하였다. 폐렴과 기관지염과 같은 하기도 감염이 전체환자의 75%를 차지하였고 분리 검체 역시 객담이 84%로 가장 많았다. 환자의 71%가 기저질환을 가지고 있었으며, 그 중에 만성 폐쇄성 폐질환, 심혈관 질환, 악성종양, 당뇨병이 대부분이었다. 혈청형으로는 nontypeable 형이 68%로 가장 많았고 b형은 한 예도 없었다. β-lactamase 생성율은 63.2%였고, β-lactamase 양성균주의 항균제 내성율이 음성균주에 비하여 높았으나 β-lactamase 생성 여부에 관계없이 cefotaxime, azithromycin, ciprofloxacin에 대하여 100%의 감수성을 나타내었고 cefaclor, cefuroxime에 대해서는 10% 이하의 낮은 내성율을 보여 이들 항균제들이 치료에 효과적일 것으로 사료된다. 세포외막 단백분석에서는 C형과 D형이 전체의 64%로 가장 많았으며, 혈청형과의 유의한 연관성은 보이지 않았다. 결론 : 성인에서 H. influenzae는 주로 만성 기저질환자에서 급성 호흡기감염 또는 만성 폐쇄성 폐질환의 급성 악화를 유발한다. 기존의 보고에 비해 β-lactamase 양성율이 증가하였고, 이에 따른 항균제 내성율도 증가하여 항균제의 선택에 유의하여야 할 것으로 생각된다. 세포외막 단백분석상 특정한 유형의 균주에 의해 감염이 집중적으로 발생하고 있어 향후 역학 조사의 도구로 이용할 수 있겠다. Purpose : H. influenzae is one of the common causative microorganisms of respiratory tract infections in adults. Recently. β-lactamase producing, ampicillin-resistant H. infiuenzae has become worldwide problem as well as in Korea. We studied to investigate the clinical features and microbiologic characteristics of H. infiuenzae infections in adults. Materials & Methods : From March 1998 to September 1999, 68 patients were enrolled in this study. Clinical features of H. infiuenzae infections were investigated, 68 isolates were subjected to the β-lactamase test, and 33 isolates were used for serotyping. biotyping, antibiotic susceptibility and outer membrane protein (OMP) analysis. Results : Mean age of study patients was 68 years-old and the acquisition rate in community was 85%. Pneumonia and bronchitis were the most common type of infection such as 80%, sputum was the most common clinical specimen for H. mQuenzae isolation. 70% of patients had chronic underlying diseases. Non-typeable strains were 68% and β-lactamase producing rate was 63%. There was no difference in the clinical features and prognosis of H. influenzae infection between the β-lactamase positivie and -negative groups. The susceptibility of cefotaxime, azithromycin, and ciprofloxacin was 100% and that of cefaclor, cefuroxime was under 10% in spite of β-lactamase positivity. In OMP analysis, C and D types were dominant (64%). Conclusion : H. influenzae caused acute respiratory infections in adults with chronic underlying disorders. This study shows higher β-lactamase producing rate and antibiotic-resistance rate than that were reported previously. OMP analysis shows that two major types of strains cause clinical infections intensively.

박경식,이승현,최석영,박태규,이동화,이찬우,정성복,이인규 啓明大學校 醫科大學 1997 계명의대학술지 Vol.16 No.3

부신피질 자극호르몬 단독결핍은 국내에서 7례만이 보고된 희귀 질환이며 병인 및 경과 등 아직 불분명한 측면이 많다. 이는 질환지체의 희귀성도 있지만 치료후 자연경과에 대한 장기적인 추적검사가 이루어진 경우가 드물기 때문이기도 하다. 저자들은 비특이적인 전신증상을 주소로 내원한 폐경기후의 56세 여자 환자에서 자가면역질환의 증거없이 고프로릭틴혈증을 보인 부신피질 자극호르몬 단독결핍 1례를 경험하고 1년간의 부신피질호르몬 대치요법후 추적검사를 실시하였기에 문헌 고찰과 함께 보고하는 바이다. Isolated ACTH deficiency is a rare disorder which shows secondary adrenal insufficiency with normal states of other pituitary hormones. A 56-year-old postmenopausal woman complaining general weakness and intermittent mental confusion presented negligible serum cortisol and ACTH level with hyperprolactinemia and mild hyponatremia. Rapid ACTH stimulation test did not show significant increase of serum cortisol level. Combined pituitary stimulation test showed negligible response of cortisol and ACTH, and slightly decreased response of prolactin and gonadotropin. But the responses of TSH and GH were normal. There was no evidence of organic pituitary of hypothalamic lesion in brain MRI and antithyroid autoantibody was not detected in serum. After receiving 12 months of glucocorticoid replacement therapy, she skipped the medicine for 3 weeks and we performed follow-up endocrinologic tests. Serum ACTH and cortisol level was also negligible and prolonged ACTH simulation test showed normal response of serum cortisol. CRF stimulation test showed no response of serum ACTH. Basal prolactin level was decreased to near normal and combined pituitary stimulation test showed normal response of prolactin with slightly blunted response of TSH and GH. We concluded that the case was nonautoimmune origined isolated ACTH deficiency which was accompanied by hyperprolactinemia and resultant deficiency of gonadotropin, so we report this case with review of literatures.

대전시 노은 도매시장에서 채취한 6종의 채소류 중 농약잔류량을 조사한 후 이에 대한 위해성 평가를 실시하였다. 전체 100건의 분석시료 중 농약이 검출된 시료의 비율은 46.0%이었고, 잔류허용기준 초과비율은 6.0% 이었다. 검출비율이 높은 시료는 상추(85.0%), 깻잎(80.0%), 오이(60.0%) 순이었고, 상추 3건, 깻잎 3건이 허용기준을 초과하였다. 살균제는 dicar-boximide계, 유기염소계, azole계 농약, 살충제는 유기인계, 합성 pyrethroid계 농약이 많이 검출되었다. 검출빈도가 높은 성분은 procymidone, chlorpyrifos, chlorothalonil, cypermethrin, EPN의 순이었다. 위해성을 평가하기 위해서 각 농작물에 대한 농약의 추정 섭취량과 ADI를 비교한 결과, 허용기준을 초과한 깻잎의 bitertanol, triflumizole, iprobenphos가 다른 성분에 비하여 높은 비율을 보였다. 그러나 각 농산물의 식이섭취량이 적어 ADI에 대한 추정섭취량의 비율이 0.46%이하로 나타나 그 영향이 매우 낮은 것으로 판단되었다. Pesticide residues in some vegetables collected at Noeun wholesale market in Daejeon were surveyed and assessed their risk In 100 samples, the detection rate of pesticide was 46.0% and the rate exceed MRL was 6.0%. Commodities showing high detection rate were lettuce(85.0%), perilla leaf(80.0%) and cucumber(60.0%). Dicarboximide, organochlorine, and azole fungicides and organophosphorus and pyrethroid insecticides were detected. Detection frequency of pesticide was in the order of procymidone, chlorpyrifos, chlerothalonil, cypermethrin and EPN. When the estimated intake amount of the pesticides were compared with ADI to assess their risk, bitertanol, triflumizole and iprobenphos in perilla leaf were higher rate than the other vegetables. However the total amounts of intake of pesticides were estimated to less than 0.46% of ADI.

In order to evaluate the efficacy and safety of risperidone, 10 patients with chronic schizophrenia were examined for 8 weeks in a silgle-open study. After the wash-out period of 1 week, risperidone was administered. Efficacy was evaluated by means of Positive and Negative syndrome Scale for Schizophernia(PANSS) and Clinical Global Impression(CGI). Safety assessment included the Extrapyramidal Symptom Rating Scale(ESRS), vital signs, body weight, ECG, and laboratory tests. The results were as follows 1) On the PANSS total score, there was significant improvement of total score after 1 week (P<.05) of administratiom. 2) On the PANSS positive and negative subscal, there were significant improvement of posotive and negative scores after 2 weeks (P<.05) of administration. 3) On the PANSS general psychopatholgy subscals, there were significant improvement of general psychopathologyscores after 1 week (P<.05) of administratiom. 4) On the CGI, there was significant decreasement of clinical impression of severity of schizophrenia score after 2 week (P<.05) of administration. 5) A statistically significant increase in body weight (P<.05) was observed after 8 weeks of administration. 6) EPS reached the peak at the end of the 1st week of administration of risperidone (11.8± 24.25) but they were easily relieved by addition of benztropine and clonazepam. There was not significant change in laboratory tests, vital sign, ECG after 8 weeks of administration. These results suggest that Risperidone is an effective antipsychotics and clinically safe except for increased body weight in chronic schizophrenia.

To develope activating agents of immune system from natural products, we focused on the activation of T and macrophage cells. We chose 35 kinds of candidates to do this. We used in vitro method such as Fetal Thymic Organ Culture(FTOC) system and bacterial phagocytic method to do test the inducing ability for T cell activation and phagocytosis of peritoneal macrophages. The results obtained from above way are as follows: Atractylis Rhizoma, Japanese touchwood and Astragali Radix showed T cell activating effect, particullary Astragali Radix is affecting most strongly between these 3 samples. Wherease Polyporus and corni Fructus which is known to be T cell activator are affecting on the decrease of fetal thymic T cells. Malvae Semer used as negative control showed predicted results. From the flow cytometric analysis, the results from Atractylis Rhizoma, Japanese Touchwood. Astragali Radix, Polyporus and Corni Fructus showed large population of CD4 positive helper T cells. Malvae Semer affect on the increasing of CD8 positive T cells, as opposed to the samples known to be T cell activating agents. From the analysis of phagocytic activityof peritoneal macrophage cells, Angelicae Gigantis Radix, Polyporus and Codonopsi Radix showed the increasing effect on phagocytic activity. Codonopsi Radix is particullary affecting most powerfully. Phellodendri Cortex which is known to be the activating agent on macrophage showed negative effect.

일반가옥 및 실험실에서 라돈농도, 평형등가농도 및 평형인자의 농도 변화를 검토하였으며, 환기조건에 따른 평형인자, 비흡착 라돈자손 비율의 변동 특성을 검토하였다. 가옥 7개 지점에서의 평균 라돈농도, 평형등가농도 및 평형인자는 각각 30 Bq m^-3, 19.6 Bq m^-3 0.65였다. 한편, 실험실 3개 지점에서의 평균 라돈농도, 평형등가농도 및 평형인자는 55.0 Bq m^-3, 31.9 Bq m^-3 , 0.58였다. 실내에서의 라돈농도, 평형등가농도 및 평형인자는 새벽 및 아침시간에 높고 오후 4시부터 밤 10시 사이에 낮아지는 주기적인 특성을 나타내었다. 환기상태가 좋은 경우가 환기상태가 나쁜 경우에 비해 평형인자는 낮아지는 반면, 비 흡착 라돈자손 비율이 증가하는 경향을 나타내었으며, 평형인자는 기압, 습도에 비례하는 반면, 온도에는 반비례하는 관계를 나타내었다. The variation characteristics of radon concentration, equilibrium equivalent concentration and equilibrium factor in some houses and laboratory buildings have been studied. The variation of equilibrium factor and the unattached fraction of radon progeny with ventilation condition have been also estimated. The averages of radon concentration, equilibrium equivalent concentration and equilibrium factor were 30 Bq m^-3, 19.6 Bq m^-3 and 0.65 in seven houses, while 55.0 Bq m^-3, 31.9 Bq m^-3 and 0.58 in three laboratory buildings, respectively. The diurnal variation of radon concentration, equilibrium equivalent concentration and equilibrium factor in indoor showed a typical pattern that the radon concentration, equilibrium equivalent concentration and equilibrium factor increased at dawn and morning, while decreased at midday and evening. While the equilibrium factor rate deceased in the indoor environment which was well ventilated, the unattached fraction of radon progeny increased. The equilibrium factor was in proportion to air pressure and humidity of indoor, whereas in inverse proportion to temperature.

제7차 환경교육과정 특성에 대한 미학적 고찰

이민부,박승규,장의선 한국지리환경교육학회 2001 한국지리환경교육학회지 Vol.9 No.1

제 7차 환경과 교육과정에서는 초등학교와 중·고등학교에서의 환경교육이 균형있는 환경인식을 형성할 수 있도록 가치관, 지식, 기능, 태도, 참여 등 다양한 영역에 걸쳐서 목표를 제시하고 있다. 내용영역에서도‘인간과 환경’, ‘환경문제’, ‘환경보전’이라는 세 영역을 초등학교와 중·고등학교에서 계속적으로 다루면서 심화·확대시키고 있다. 특히 고등학교에서는 이들 세 영역 이외에‘환경과 사회’의 영역 등을 추가하여 학습자들이 자연과학적인 측면에서의 이해에서 벗어나 인문·사회과학적인 측면에서의 접근을 통해 우리의 삶과 환경과의 밀접한 관련성을 인식하고, 환경문제해결에 참여할 수 있도록 하고 있다. 그러나 제 7차 환경과 교육과정에서도 학습자들의 일상적인 삶의 영역과의 관련성을 염두에 두고 있으면서도 대부분의 내용들이 환경파괴나 환경오염, 그리고 그에 대한 대책 등과 관련된 것들이 대부분이어서 학습자들로 하여금 환경적 감수성이나 환경에 대한 아름다움을 통한 환경교육의 가능성이 그만큼 제한되어 있다. 따라서 본 연구에서는 경관을 매개로 한 미학적인 관점에서 제 7차 학교급별 환경교육의 특성을 비판적으로 살펴보고자 한다. The 7th national curriculum for environmental education in elementary and secondary school focuses on consideration of learner’s ability, learner’s activities, and learner’s region of everyday life. The contents of environmental education are scattered subjects in elementary schools and an independent subject as ‘Environment’ in middle school and ‘Environment and Ecology’ in high school of the secondary school. With upgrading of schools, the aims and activities of environmental learning move up from valuecentered, through activity-oriented and to cognition-centered. The esthetic considerations, such as landscape sensitivity, are required for better environmental education curriculum focusing on value and attitudes in everyday life space or region.

Testosterone Propionate의 投與가 어린 숫흰쥐의 副腎에 미치는 影響

李揆丞 충남대학교 농업과학연구소 1976 農業技術硏究報告 Vol.3 No.2

In order to find the effects of testis function on adrenal gland, immature male rats were administered by 20 mg of testosterone propionate with 10 days interval for 50 days, and their adrenal weights and histological changes were compared with those of normal ones, and the results obtained were as follow : Adrenal weight was increased with the period of treatments, and especially the significant difference was recognized after 30 days. Of the zones in adrenal gland, the portion of zona fasciculata and reticularis increased significantly after 20 days and 30 days, respectively, while that of adrenal medulla was decreased significantly after 20 days. In histological changes, hypertrophy and vacuolization were observed in zona fasciculata and reticularis after 20 days, but no changes were recognized in zona glomerulosa and adrenal medulla.
