심박변이율의 감소는 심근 경색 환자에서 예후의 악화와 관련되어 있다. 심박변이율 중 very low frequency가 심부전환자의 예후를 판단할 수 있는 독립적 인자로서 사용이 가능하다고 보고된 바 있으며, 심실의 압력 증가에 반응해서 생성되는 B-type natriuretic peptide가 심근 경색의 예후 인자로서 사용할 수 있음 역시 보고된 바 있다. 본 연구에서는 심근경색 모델을 제작하여 일정의 회복 기간을 거친 다음 다시 일정 기간의 스트레스를 겪게 한 후 심박변이율의 변화 및 심실 조직에서의 BNP 발현 정도를 비교하여 스트레스에 의한 영향을 관찰하고자 하였다. Sprague-Dawley계 수컷 흰쥐 15마리를 대상으로 하였다. 실험동물은 인위적 스트레스 및 수술을 받지 않은 대조군(CON, n=5), 심근경색 수술을 받은 후 restraint stress를 받지 않은 군(MI+No Stress, n=5), 심근경색 수술을 받은 후 1주일 동안 restraint stress를 받은 군(MI+Stress, n=5)으로 분류하였다. 심근경색 모델 제작 직후 15분 이상 심전도의 변화를 기록하였으며, 2개월 정도 후 심근경색 수술을 받은 동물을 두 군으로 나누어 그 중 한 군에는 1주일 동안 restraint stress를 가한 후 restraint stress를 가하지 않은 동물과 심박변이율을 비교 분석하였다. 심실 조직은 좌심실 전벽 부위의 위축을 관찰할 수 있었고, 대식세포에 의하여 응고, 괴사된 심근세포의 탐식과 혈관이 풍부한 육아조직 및 섬유 변화를 볼 수 있었다. 심박변이율은 심근경색 수술을 받은 직후 심박수는 유의한 증가를 보였고, standard deviation of the normal to normal intervals (SDNN), very low frequency (VLF) 및 low frequency (LF)의 유의한 감소를 보였다. 심근경색 수술을 받았던 동물에서 두 달 정도의 회복 기간을 거친 후 스트레스를 받지 않은 군은 심박수 및 기타 심박변이율 분석에서 SDNN 값을 제외하고는 정상군과 유의한 차이를 관찰할 수 없었던 반면 1주일 동안 스트레스를 받은 군에서는 심박수가 다시 유의하게 증가했을 뿐만 아니라 SDNN, VLF 및 LF 역시 정상군과 유의한 차이를 보였다. 이상의 결과를 종합하면 심근경색 동물에 대해 1주일 동안 스트레스를 가한 결과 심박변이율이 감소하고 심실에서의 BNP 발현은 더욱 증가하여 악화함을 보여주고 있다. Diminished heart rate variability (HRV) is associated with less favorable prognosis after myocardial infarction (MI). It has been reported that very low frequency (VLF) power in HRV analysis is an independent risk predictor in patients with congestive heart failure and B-type natriuretic peptide (BNP) can be used as a prognostic factor of MI. The purpose of this study was to investigate whether stress has an effect to the changes of BNP expression and/or heart rate variability in MI model in rats. Male Sprague-Dawley rats were divided into 3 groups: control group (CON), MI group (MI+No Stress), and MI followed by stress group (MI+Stress). MI+Stress group rats were raised for a two month recovery period after the operation, followed by being exposed to restraint stress for 2 hours per day for 1 week. Electrocardiogram was recorded after the operation and the last day after 1 week of stress. The frequency components of HRV were calculated in the frequency domain such as VLF, low frequency (LF), high frequency (HF) and so on. In HRV analysis, standard deviation of the normal to normal intervals (SDNN) was significantly reduced in both groups compared to the control group. VLF and LF also were significantly reduced in MI+Stress group compared to the control groups. In addition, BNP expression in western blotting was shown the strongest bands in MI+ Stress group among experimental groups. These results suggest that BNP and HRV were aggravated by stress in MI rat model. (Korean J Str Res 2010;18:275∼285)

강근영,양규호,최남기,김선미 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.3

매복치아란 어떤 원인에 의하여 구강점막이나 약골내에서 치아의 맹출이 중지된 상태를 말하며, 악궁내의 어떠한 치아도 매복될 수 있으나 가장 흔하게 이환되는 치아는 상, 하악 제 3대구치, 상악 견치, 상, 하악 제 2소구치, 상악 중절치의 순으로 나타난다. 이 중 상악 영구 전치의 매복률은 0.1-0.5%정도이며 매복 원인으로는 여러 가지가 있으나 유전치의 외상, 과잉치, 치근단 병소로 인한 매복이 흔하며 조기에 적절히 치료되지 못하면 정중선의 변위, 인접치에 의한 맹출공간 감소, 치조골 높이의 차이 등의 결과를 유발한다. 치료로는 주기적 관찰방법, 매복치의 맹출로가 정상이며 치근이 미완성일 경우 상부 연조직과 경조직을 단순히 제거하여 맹출을 유도하거나 외과적 노출 후 매복치를 교정 하는 방법, 치아이식술, 발치 등을 시행할 수 있다. 본 증례들은 상악 중절치의 맹출 지연을 주소로 본원에 내원한 환아들로 상악 중절치의 변위 배복을 외과적 노출과 교정적 견인을 시행하여 양호한 결과를 얻어 보고하는 바이다. Tooth impaction is defined as a cessation of the eruption of a tooth at the level of the oral mucosa or alveolar bone by any causes. Any tooth in the dental arch can be impacted, but the teeth frequently involved in a descending order are the mandibular and maxillary third molars, the maxillary canines, the mandibular and maxillary second premolars, and the maxillary central incisors. In these teeth, impaction of maxillary incisor occurs in about 0.1-0.5% and major causes are trauma, supernumerary teeth and periapical inflammation of primary maxillary incisor. Delayed eruption of a maxillary central incisor results in midline shift, the space's being occupied by an adjacent tooth and different levels of alveolar height. Treatment options are observation, surgical intervention, surgical exposure and orthodontic traction, trans-plantation and extraction. These cases were about the patients with delayed eruption of maxillary central incisor. We surgically exposed impacted tooth and guided it into normal position by the orthodontic traction. At the completion of traction, the maxillary central incisor was positoned fairly within the arch and complications such as root resorption were not observed.

服飾변천 과정에서 Sleeve Design의 特徵(Ⅲ) : 16세기를 中心으로 Sixteenth Century

姜京子,鄭雲子,鄭福南,秋美先 慶尙大學校 1985 論文集 Vol.24 No.1

The sleeve design of costume had an impact on the general pattern of costume in 16th century. In this paper the characteristics of the change sleeve design and the method of construction were studied according to the criteria suggested by Cunnington. The results of the study can be summerized 35 follows. The costume in 16th century was not quite different from those in the past centuries, but the costume tended to have more varied detail and trimming and they were based on the graceful silhouette. In 16th century, there were no uniformity and regularity of sleeve design. But it was general trend that sleeve was expanded by using pad and slash of· it had very tight sleeve in the early part of 16th century. The tight sleeve of women's costume in Germany was tailored in two part, and it suggested the improved technic of cutting. On the other hand, the sleeve of women's costume in France and England had the artificially distorted from that had expanded form in the lower part. In the middle part of 16th century, the form of sleeve became very complicated and it was inconvenient for the wearer to put it on. Therefore, in France, the sleeve was made independently. When one put it on, a string was used to connect it to costume and to decorate with E´aqaulette. The upper part and wrist part of elbow sleeve of Over-coat in Italy were very tight, and the middle part of it was loose. The typical pattern of women's costume that had expanded sleeve in lower part was in fashion. This form disappeared in 13th century and appeared again in 14th and 15th centuries. In the part of 16th century, the sleeve design manifested the aesthetic sense of that period, Many kinds of sleeves Including the tight one, baggy one, wide one and the hanging one were used. The most characteristic sleeve of this period was the expanded leg of mutton sleeve and it was in fashion for men and women in upper classes of France and England. In short, all kinds of sleeve suggested by Cunnington appeared in this period. They include both the natural and artificial forms. As the sleeve design had varied form and the expression in detail was stressed. These style helped to harmonize the sleeve with the design for body,and they contributed to increase the splendor of costume in 16th century.

개조개, 백합, 피조개 및 꼬막 발의 점액질 성상을 PAS 반응, AB pH 2.5 및 AB pH 2.5-PAS, AB pH 1.0, AF pH 1.7-AB pH 2.5 염색 등의 prelectin법으로 관찰하였다. 개조개, 백합, 피조개 및 꼬막 발은 상피, 상피하결합조직 및 근층의 3층으로 구성되었으며 모든 종에서 발의 표면은 단층섬모원주상피로 덮여 있었다. 백합의 발샘의 점액샘꽈리는 작은 구형이고 소수이며 산재성이었으나 그외 종에서는 큰 구형이고 다수이며 밀집해서 나타났다. 발샘의 도관은 개조개와 피조개가 백합과 꼬막보다 더욱 발달되어 있었으며 피조개와 꼬막은 발의 선단부에 깊이 파인 홈이 나타났으며 흠에 접한 상피하결합조직에 작은 구형의 과립이 밀집해 있었다. 상피세포의 섬모에서 개조개와 백합은 강sulfomucin을, 각각 소량, 소량 내지 중등량 함유하고 있었으며 피조개와 꼬막은 sialomucin과 중성점액질을 중등량 내지 소량 함유하고 있었다. 상피 세포의 세포질은 백합에서만 강 sulfomucin을 미량 내지 소량 함유하고 있었다. 발샘의 도관은 개조개와 백합은 강sulfomucin만을 소량 내지 중등량, 피조개와 꼬막은 소량의 중성점액질과 강 sulfomucin을 중등량 또는 중등량 내지 상당량을 함유하고 있었다. 발샘의 점액샘꽈리에서 개조개 및 백합은 강sulfomucin과 약sulfomucin이 섞여 있었으며 개조개는 중등량 내지 상당량, 백합은 소량 내지 중등량 이었고 피조개와 꼬막은 강sulfomucin만을 함유하였는데 피조개는 중등량 내지 상당량을, 꼬막은 상당량 내지 다량이었다. 발의 결합조직 과립은 피조개에서 상당량 내지 다량의 강sulfomucin을, 꼬막에서 상당량 내지 다량의 중성점액질과 강sulfomucin을 함유하였다. The histochemical properties of mucins of the foot of Saxidomus purpuratus, Meretrix lusoria, Scapharca broughtonii and Tegilltarca granosa were studied prelectin methods, i.e., PAS, AB pH 2.5, Ab pH 2.5-PAS, AB pH 1.0 and AF pH l.7-ABe pH 2.5 stainings. The foots of Saxidomus purpuratus, Meretrix lusoria, Scapharca broughtonii and Tegillarca granosa were composed of three layers, i.e., epithelium, subepithelial connective tissue and muscular layers. The epithelia were lined by simple ciliated columnar cells. The foot gland of Meretrix lusoria consist of multicellular mucous acini were small spheroid in shape and a few in number and scattered, while these acini of other species were large spheroid in shape and were numerous and crowed within connective tissue. The ducts of foot glands were more developed in Saxidomus purpuratus and Scapharca broughtonii than in other species, Particularly, Scapharca broughtonii and Tegillarca granosa showed a deep groove in apical portion of the foot and small spherical granules were found in the subepithielial connective tissue in this portion. The cilia of epithelial cells of the foot gland in Saxidomus purpuratus and Meretrix lusoria were contained only small amounts or small to moderate amounts strong sulfomucins, respectively, while these alia in Scapharca broughtonii and Tegillarca granosa were contained moderate amounts or small to moderate amounts of sialomucins and neutral mucins, respectively. The epihtelial cytoplasm of Meretrix lusoria contained only minimal to small amounts of strong sulfomucins. The ducts of the foot glands in Saxidomus purpuratus and Meretrix lusoria were contained only small to moderate amounts of strong sulfomocins, while these ducts of other spicies were contained small amounts of neutral mucins and moderate or moderate to considerable amounts of strong sulfomucins. The mucous acini of these glands in Saxidomus purpuratus and Meretrix lusoria were contained moderate to considerable and small to moderate amounts of strong and weak sulfomucins, respectively. however, these acini were contained moderate to considerable amounts of strong sulfomucins in Scapharca broughtonii and considerable to large amounts of strong sulfomucins in Tegillarca granosa. The granules within connective tissue of the foot in Scapharca broughtonii were contained considerable to large amounts of strong sulfomucins, but these anules in Tegillarca ganosa were contained considerable to large amounts of neutral mucins and strong sulfomucins.

This study was conducted by critical review analyzing literatures of theories focused on changes of health behaviors. 5 theories-TRA, HBM, Self-Efficacy, Social Support, and Locus of Control-were selected among many theories of health behaviors. Theories were summarized, and models and concepts of theories were described. The results of this study were follows : 1. health behaviors could be classified into preventive behaviors and curative behaviors. 2. Most conceran of previous studies in this field was on health behavior execution itself or on its outcome. 3. the focus of previous studies was on initiation, maintenance, facilitation, and change of preventive and curative behaviors. 4. Factors affecting on health behaviors were demographic factors as exogenous variables and intrapsychic and extrapsychic factors as endogenous variables. 5. Previous studies tested predictability and explicability of these theories onhealth behaviors and identified factors affecting health behaviors most. 6. concepts of TRA, SELF-Efficacy, and Social support had higher explicability on health behaviors than concepts of HBM and Locus of control. From results of this study, we suggested the direction and considerations for futher nursing studies related with these theories. And we derived testable propositions from relationship between concepts and each others.

The purpose of this study was to investigate the relationship of the skeletal maturity of hand-wrist and the development of mandibular third molar in subjects with class I and class III malocclusion. The subjects used in this study were 304 children(149 boys, 155 girls) with class I malocclusions and 308 children(153 boys, 155 girls) with class III malocclusions, ranged from 8 to 15 years of age. Hand-wrist radiographs and panoramic radiographs were used to evaluate the stage of skeletal maturity and teeth development. Fishman s method for the skeletal maturity stages of the hand-wrist and new six-developmental-stage method for the calcification stages of mandibular third molars were analyzed. The results were as follows: 1. In subjects with class I and class III malocclusion, skeletal maturity of the hand-wrist occured earlier in females than in ma1es(p<0.05), while the calcification stages of mandibular third molars were no significant gender differences. 2. There were no significant differences between the groups, when comparing the skeletal maturity stages of the hand-wrist and the calcification stages of mandibular third molars between subjects with the class I and the class III malocclusion. 3. The correlation coefficients between the calcification stages of mandibular third molars and the skeletal maturity stages of the hand-wrist in subjects with class I and class III malocclusion showed a high interrelationship(p<0.01). 4. The correlation coefficients between the calcification stages of mandibular third molars and chronological age in subjects with class I and class III malocclusion showed a high interrelationship (p<0.01). As a result, there were no significant differences between class I and class III malocclusion group for skeletal maturity of the hand-wrist and third molar development.

강인성,양규호,최남기,김선미,오종석 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.2

Chlorhexidine dihydrochloride와 불화나트륨은 구강 내 세균을 억제하고 치태의 형성을 억제하기 위하여 많이 사용되고 있는 물질이다. 그러나 구강에는 여러 종류의 세균들이 상주하며 이들 물질에 대한 감수성도 다르다. 본 연구에서는 chlorhexidine dihydrochloride와 불화나트륨에 의해 Streptococcus mutans의 인공치태 형성이 억제되었을 때 Streptococcus mutans, Streptococcus sobrinus, Streptococcus oralis, Streptococcus salivarius의 증식에 미치는 이들 물질의 영향을 관찰하여 다음과 같은 결과를 얻었다. Streptococcus mutans를 8시간 배양하면 와이어에 형성된 인공치태 무게는 106.1±18.1㎎이었으나, 1.0μM chlorhexidine dihydrochloride를 첨가하면 5.1±1.5㎎으로 감소되었다(p<0.05). 이 때 배양액의 흡광도도 감소되었다. Streptococcus sobrinus의 배양액 흡광도는 감소되었으나 Streptococcus oralis에서는 감소되지 않았고 Streptococcus salivarius에서는 배양 8시간에 감소되었다가 배양 24시간에 대조군과 차이가 없었다. 배지에 3.0 mM 불화나트륨을 첨가하여 Streptococcus mutans를 8시간 배양하면 와이어에 인공치태 무게는 26.7±8.3㎎으로 감소되었다(p<0.05). 이 때 배양액의 흡광도도 감소되었다. Streptococcus sobrinus와 Streptococcus oralis에서의 배양액의 흡광도도 감소되었으나 Streptococcus salivarius에서는 거의 감소되지 않았다. 이상의 결과는 Streptococcus mutans의 인공치태 형성을 억제하는 chlorhexidine dihydrochloride와 불화나트륨 농도에서 Streptococcus의 여러 종의 감수성이 각각 다르다는 것을 시사하였다. Chlorhexidine dihydrochloride and sodium fluoride have been used as agents inhibiting the replication of oral bacteria and the formation of dental plaque. There are various kinds of bacteria with different sensitivity against these agents. In this study, chlorhexidine dihydrochloride and sodium fluoride were studied about their effects on the replication of Streptococcus mutans, Streptococcus sobrinus, Streptococcus oralis and Streptococcus salivarius at their concentrations inhibiting the formation of artificial plaque by Streptococcus mutans. When Streptococcus mutans was cultured for 8 hours in the media added with l.0μM chlorhexidine dihydrochloride, the weight of formed artificial plaque was decreased to 5.1 ±1.5mg compared with 106.1±18.1mg of the control(p〈0.05). At the same time, the optical density of cultured media was decreased. The optical density of cultured media was slightly decreased in Streptococcus sobrinus. but was not decreased in Streptococcus oralis. The optical density of Streptococcus salivarius was decreased at 8 hours-incubation, was not decreased at 24 hours-incubation. When Streptococcus mutans was cultured for 8 hours in the media added with 3.0 mM sodium fluoride. the weight of formed artificial plaque was decreased to 26.7i8.3 mg(p〈0.05). At the same time. the optical density of cultured media was decreased. The optical density of cultured media was decreased in Streptococcus sobrinus and Streptococcus oralis, but was slightly decreased in Streptococcus salivarius. These results suggest that at the concentration of chlorhexidine dihydrochloride and sodium fluoridehe inhibiting the formation of artificial plaque by Streptococcus mutans, different species of genus Streptococcus show the different sensitivity against these agents.

상악 협측 치은에 발생한 모세혈관종 치험례 : A CASE REPORT

강근영,양규호,최남기,김선미 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.4

혈관종은 혈관의 증식에 의해 발생하는 양성 종양으로 유아와 어린이에서 호발한다. 대부분 진성종양으로 보다는 과오종(hamartoma)으로 보며 구강내 호발부위는 입술, 혀, 협점막 구개부 등이다. 임상소견은 편평하거나 융기된 적청색 병소로 보통 단발성이다. 조직학적 소견을 통해 모세혈관성(capillary), 해면상(cavernous), 혼합성(mixed), 경화성(sclerosing)등으로 분류되며 확진된다. 본 증례는 6세 남자 환아가 치은에 뭐가 났다는 것을 주소로 전남대학교 병원 소아치과에 내원하였다. 임상검사 결과 #62, 63 부위의 부착치은에 딸기모양 종물(mass)이 관찰되었다. 조직검사 시행 결과 모세혈관종으로 확진되었으며 외과적 절제로 양호한 결과를 얻었기에 보고하는 바이다. 혈관종은 재발이 드물며 악성전환이 없지만 출혈 경향이 높으므로 임상적 시술시 주의가 요구된다. The hemangioma, a benign proliferation of blood vessel, is the most common tumor of infancy and childhood. In many instances, the lesion probably represents a hamartoma or malformation rather than a true neoplasm. In the oral cavity, common sites are lips, followed by tongue, buccal mucosa and palate. Clinical characteristics appear as a flat or raised reddish-blue lesion and are generally solitary. They are classified on the basis of their histological appearance into capillary, mixed, cavernous or a sclerosing variety. A 6-year-old male of this case was referred to the Department of Pediatric Dentistry, Chonnam National University with a chief complaint of swelling lesion on gingiva. The strawberry appearance mass was detected by clinical examination on attached gingiva at the upper left primary lateral incisor and canine. Surgical excision and biopsy were carried out for histological examination and the lesion was diagnosed with a capillary hemangioma. The risk of recurrence after this therapy is rare, and there is no malignant transformation. Despite their benign origins and behaviour, hemangiomas in the region of oral cavity are always clinically important to the dental profession because of bleeding tendency.
