Back extension exercises have been used for rehabilitation of the injured low back, prevention of injury, and fitness training programs. However, excessive loading on low back can exacerbate existing structural weakness. The purpose of this study was to compare muscle activity of low back muscles during back extension exercises. Twenty healthy male subjects were evaluated, Electromyographic (EMG) activities of low back muscles at L1 and L5 level were recorded during seven different back extension exercises and two reference tasks by surface EMG and saved for data analysis. Reference tasks of lifting 20% and 40% of their body weight were included for comparison. The result were as follows: 1) Single-arm extension and single-leg extension exercises on quadruped position appeared to constitute a low-risk exercise for initial extensor strengthening. 2) When arm extension was combined with contralateral leg extension on quadruped position, EMG activities of low back muscles were increased, 3) EMG activity of low back muscles was highest during the trunk extension exercises on prone position. 4) EMG activities of low back muscles during arm and leg extension exercises on quadruped position were less than those of reference task of lifting 40% of their body weight. These results have important implications for progressive back extensor muscle

The aim of this paper is a historical description of the changes which affected the phonoogical structure of Greek over the period from Proto-Indo-European language to modern Greek. From the purely phonological point of view, Greek can be divided as follows. Ⅰ. Proto-Greek (∼1400 BC) : This is the period which the changes that are unique to Greek and made it different from the other Indo-European languages took place. The changes are 1) devocalization of the aspirates, 2) loss of the labio-velars, 3) loss of /y/, 4) the change of initial /s/ to /h/. Ⅱ. Classical Greek (700BC∼330BC) : The changes of this period are 1) monophthongization of /ei, ou/ to /e˙, u˙/, 2) lowering of /e˙, o˙/ to /ε˙,??/, 3) fronting of /u˙, u, oi/ to / u??, u¨, o¨i/. Ⅲ. Hellenistic Koine Greek (330BC∼6C AD) : This period can be devided furthermore into two stage. In the first stage (4C BC∼2C AD) the changes occured as follows. 1) monophthongization of /a˙i, ε˙i, ??i/ to / u˙, ε˙, ??/ respectlively, 2) raising of /e˙/ to /l˙/. And in the second stage (2C AD∼4C AD) we see 1) monophthongization of /ai/ to /ε˙/ and /o¨i, u¨i/ to /u¨/, 2) raising of /ε˙/ to /l˙/, 3) spirantization of /p^h, h^h, k^h/ and /b, d, g/ to /f, θ, x/ and /v, ð, γ/ respectively, 4) spirantization of /u/ in /au,εu/ to /f/ or /v/ according to the environments, 5)loss of /h/, 6) creation of new opposition between /s/ and /z/, 7) transition of pitch-accent to stress-accent and loss of the distinction between long vowels and short vowels. Ⅳ. Modern Greek (6C AD∼): In this period we have 1) merging of /u/ with /i/, 2) change of unstressed /i/ to /y/, 3) emerging of /b,d,g/ and /ts, dz/. Based on the above observations on the historical changes in Greek phonological structure we assume two principles which seem to govern the language change : 1) a phonological system tends to keep up the structural stability, 2) and to maintain the same number of phonemes if possible.

본 연구는 방위에 따른 속리산 및 오대산 삼림식생을 분석하고자 하였다. 속리산 조사구와 오대산 조사구를 방위에 따라 출현하는 주요 종의 중요치를 살펴보면 속리산의 경우 북향에서는 쇠물푸레, 벚나무, 개옻나무, 굴피나무, 참회나무 등 8종에 중요치가 높게 분포하고 있음을 볼 수 있고, 동향에서는 소나무, 고로쇠나무, 산초나무, 소태나무, 작살나무 등 6종이, 남향에서는 굴참나무, 졸참나무, 생강나무, 물푸레나무, 짝자래나무 등 13종이, 서향에서는 신갈나무, 당단풍, 쪽동백나무, 노린재나무, 철쭉 등 13종에 중요치가 높게 출현한다. 오대산의 경우를 보면 북향에서는 당단풍, 까치박달, 거제수나무, 음나무, 잣나무등 18종이 중요치가 높게 분포하고 있음을 볼 수 있고, 동향에서는 전나무, 소나무, 느릅나무, 산벚나무, 들메나무 등 5종이, 남향에서는 신간나무, 물푸레나무, 철쭉, 진달래, 개벚지나무 등 7종이, 서향에서는 피나무, 고로쇠나무, 난티나무, 쪽동백나무, 황벽나무 등 10종이 중요치가 높게 출현함을 알 수 있다. 이러한 결과로 볼 때 속리산에서는 남향과 서향이 각각 13종씩 26종으로 북향과 동향의 14종 보다 배에 가까운 많은 수의 나무들이 중요치가 높게 출현하고 있는 것에 반하여, 오대산에서는 북향과 동향이 각각 18종과 5종씩 23종으로 남향과 서향의 17종 보다 월등히 많게 출현함을 알 수 있다. 이와 같은 결과는 속리산과 오대산이 정반대의 현상으로 속리산이 해발고가 낮고 난온대성 수종의 우위를 점하는 것에 비하여 오대산은 해발고가 높고 냉온대성 수종이 우위를 차지하고 있는데서 오는 현상으로 보여진다.

Upper gastrointestinal bleeding is common and potentially life threatening medical emergency. Emergency endoscopy is the first choice of diagnostic and treatment measure for patients with active upper gastrointestinal bleeding. Histoacryl should be considered a second-line treatment modality when conventional treatments were failed. However, it might cause several complications. Herein, we report a case of acute pancreatitis developed after histoacryl injection therapy for active duodenal ulcer bleeding. A 71-year-old man was admitted with melena and hematemesis. On emergency endoscopy, a 2 cm sized active ulcer with bleeding from an exposedvessel was seen at the duodenal bulb. Attempts to arrest the bleeding with hemoclipping and submucosal epinephrine injection were tried, but failed. We changed the method to endoscopic histoacryl injection, and obtained hemostasis immediately. A few hourslater, after successful hemostasis, patient complained diffuse abdominal pain. Ultrasonography revealed hyperechoic heterogenous diffuse pancreatic enlargement and right pararenal space fluid collection, this ultrasonographic findings and elevated serum pancreatic enzymes are compatible with acute pancreatitis.

A 9 months intact male American bull dog with chief complaints of dry cough, dyspnea and fever was referred to the Veterinary Teaching Hospital, Chungnam National University. Based on the findings of physical examination, radiological examination, and blood and blood chemical examinations, the present patient was diagnosed into pulmonary edema secondary to primary bacterial and aspiration pneumonia. The patient was hospitalized and treated with buscopan, cephazolin and furosemide for 1 week. His activity and appetite was returned to normal and thoracic radiographs revealed that Jung was recovered to the normal condition after treatment for 7 days. The present patient was a case with pulmonary edema showed favorable therapeutic responses to proper medication.

아메바성 대장염과 연관된 Henoch-Scho¨nlein Purpura 1예

장재현,원경준,이준,변유미,이재광,김영훈,박찬국,김만우 朝鮮大學校 附設 醫學硏究所 2006 The Medical Journal of Chosun University Vol.31 No.3

Henoch-SchonIein purpura is a common form of vasculitis primarily involving the skin, the gastrointestinal tract, the joints, the kidneys, and the nervous system. The etiological investigations are essential, because triggering factors are found in approximately half the patients such as viral, bacterial and parasitic infections, drugs, toxins, systemic diseases and cancer. But it's the correlation between Henoch-SchonIein purpura and Entamoeba histolytica has been rarely reported. We report a 29-years-old woman with Henoch-SchoIein purpura complicated by the lower gastrointestinal bleeding caused by the amoebic colitis. She complained of cramping abdominal pain, lower extremity purpura and hematochezia. Cysts and trophozoites of Entamoeba histolytica were detected in her stool. Skin biopsy demonstrated the leukocytoclastic vasculitis. She was administered metronidazole 1,500㎎ a day for the treatment of amebic colitis. Her hematochezia was improved, but the abdominal pain and purpura were not. The subsequent corticosteroid therapy improved her symptoms.
