두부회전을 보이는 선천성 안구진탕의 수술료법에 대한 고찰
조윤애,정해륜 고려대학교 의과대학 1986 고려대 의대 잡지 Vol.23 No.2
Congenital nystagmus with head turn is jerky type nystagmus of which amplitude and frequency often vary in different position of gaze and which is associated with eccentric null point (neutral zone) where there is little or no movement of eyes. This may assume an abnormal head position to obtain best visual acuity. To correct the abnormal head turn, the eyes should be moved in the direction of the quick phase of nystagmus or in the same direction as the face turn. The authors experienced 5 patients with congenital nystagmus and abnormal head turn and chin elevation over 25℃. On 3 cases among these, we performed "Parks' modified Kestenbaum procedure", 4 horizontal recti muscle surgery on two cases with abnormal head turn and 4 vertical recti surgery on one case with chin elevation. We also performed "Augmented modified Kestenbaum procedure" on two cases with head turn over 35˚. In all patients, the abnormal head turn and chin elevation disappeared or improved in severity and visual acuity also improved after surgery.
生長期 鷄肝의 Phosphoenolpyruvate Carboxykinase의 變動에 관하여
趙潤愛,曺準承 慶北大學校 醫科大學 1976 慶北醫大誌 Vol.17 No.1
병아리의 孵化前後의 成長過程에 있어서 肝의 成長과 肝의 PEP carboxykinase의 活性變動을 調査하여 다음과 같은 結果를 얻었다. (1) 鷄胎肝은 14日째에 0.1g에서 直線的으로 成長하여 孵化直後엔 0.8g, 孵化後 1週日엔 1.4g으로서 旺盛한 成長을 보였다. (2) PEP carboxykinase는 鷄胎肝의 發生初期부터 mitochondria나 cytoplasm의 兩分劃에 共存하고 있었으며, 前者이 것은 始作부터 高濃度로, 後者의 것은 初期엔 아주 低濃度이었으나 成長과 더불어 增加하였다. (3) 병아리肝의 PEP carboxykinase의 活性度는 孵化後 3日頃에 最高로 높았다가 以後 下降하였다. 이 中에도 cytoplasm의 이 酵素는 孵化前後에 顯著한 上昇을 보였고 成長과 더부러 減少하였다. This study is undertaken to investigate the change of phosphoenolpyruvate carboxykinase (EC 4.1.1.32) activity during the chicken liver development. The results obtained were summerized as follows; 1. During one week before and following the hatching, the chicken liver showed a rapid growth in size and a linear increase in weight: the liver weight was 0.1g on the 14th day embryo, 0.8g immediately after hatching and 1.4 on the 7th days. 2. From early embryonic stage the enzyme was determined in both fractions of miotchondria and cytoplasm of the liver. However, the enzyme activity was high in the mitochondria but very low in the cytoplasm, with changes as the embryo chick grew. 3. The rise in the activity of the enzyme of the embryo chick liver reached the peak within 2 to 3 days following the hatching to decline to the levels of an adult liver by the 15th day after the hatching, The pattern of developmental increase in the activity of cytoplasmic enzyme was sharper thau that of the mitochondria.
양안 수직근육전이술로 치유된 양안 듀안안구후퇴증후군 1예
조윤애,오인경,Yoonae A,Cho,In Kyung Oh 대한안과학회 2006 대한안과학회지 Vol.47 No.6
Purpose: To report a male infant with bilateral Duane`s retraction syndrome treated with bilateral horizontal transpositions of vertical recti to the lateral rectus muscle. Methods: An 8-month-old boy showed bilateral Duane`s retraction syndrome with esotropia of 45PD, severe limitation of abduction (-4 and -3.5 in each eye) and mild globe retraction in both eyes. It was assumed that he inherited the condition from his father through an autosomal dominant pattern. His father showed esotropia of 25PD with -4 limitation of abduction in the left eye and a left head-turn of 10。. He also had +2 globe retraction, +1 upshoot and +2 downshoot in adduction of the left eye. Transposition of two vertical recti to the lateral rectus muscle was performed in both eyes of the boy. Results: Nine months after surgery, the boy had achieved a microesotropia of 6PD in primary gaze with stereopsis of 3000 seconds of arc and considerable improvement in abduction (-2, -1.5 in each eye). The amount of correction of esodeviation was 39PD. This favorable state was maintained at follow-up 3.5 years after surgery. Conclusions: An 8-month-old boy who had esotropia of 45PD caused by bilateral Duane`s retraction syndrome, underwent bilateral horizontal transpositions of vertical recti to the lateral rectus muscle. He achieved a microesotropia of 6PD in primary gaze and considerable improvement of abduction with only mild eyeball retraction.
A Comparison of NLSY and CPS Data
조윤애 한국데이터정보과학회 2006 한국데이터정보과학회지 Vol.17 No.3
The family income distributions of NLSY97 and CPS youth data are compared by using the generalized beta distribution of the second kind. The null hypothesis that the two data sets represent the same underlying population is rejected. The ML estimation suggests that NLSY97 data are oversampled in an income group of $11,308 or less, by about 15.7% compared to CPS data.
