        선천눈꺼풀처짐 교정술 후 발생한 난시변화

        이동섭,김준모,우경인,장혜란,Dong Sub Lee,Joon Mo Kim,Kyung In Woo,Hae Ran Chang 대한안과학회 2006 대한안과학회지 Vol.47 No.9

        Purpose: To determine postoperative astigmatic changes after surgery for congenital ptosis and the astigmatic changes depending on surgical method and to discern cases of postoperatively developed anisometropia or amblyopia. Methods: Fifty-one patients who underwent surgery due to congenital ptosis were reviewed. Refraction or cycloplegic refraction was conducted preoperatively and 3 to 6 months after surgery to measure astigmatic changes. Astigmatic changes in operated eyes were compared to control eyes. Astigmatic changes were compared depending on surgical method. Results: The mean astigmatism was 1.33±1.29D preoperatively and 1.48±1.13D postoperatively (P=0.10) and the mean astigmatic change in the ptotic and control eye was an increase in cylinder +0.56±0.55D and +0.68±0.72D (P=0.37). The mean astigmatic change of patients receiving frontalis sling was +0.57±0.67D which was similar to those who received levator resection (+0.56±0.50D). Newly developed anisometropia was found in three patients postoperatively due to an increase in astigmatism, but newly developed amblyopia was not found. Conclusions: The increase of astigmatism by ptosis surgery was not statistically significant and there was no statistically significant difference when accounting for surgical method. However, it is necessary to monitor refractive error carefully in younger patients to prevent amblyopia because postoperative increase of astigmatism can cause anisometropia.

        만성 궤양성 대장염의 추적관찰 - 단기적 치료 반응 및 재발율을 중심으로

        장동경(Dong Kyung Chang),이국래(Kook Lae Lee),김재규(Jae Gyu Kim),김용태(Yong Tae Kim),정현채(Hyun Chae Jung),송인성(In Sung Song),최규완(Kyoo Wan Choi),김정룡(Chung Young Kim),박재갑(Jae Gahb Park),이풍렬(Poong Lyul Rhee),최상운(Sa 대한소화기학회 1994 대한소화기학회지 Vol.26 No.6

        N/A Our retrospective study on 240 cases with chronic ulcerative colitis in Seoul National Uni- versity Hospital spanning from January,1975 to December,1993 revealed the following results. According to the extent of disease, there was 27.5% in proctitis, which was more frequent than that of the previous domestic reports, 15.8% in distal, 22.9% in left and 31.7% in exten- sive colitis. According to the severity of disease, there was 47.5% in mild, 32.9% in moderate and 19.6% in severe disease. There was a positive correlation between severity and extent of disease. The extraintestinal complications were not related with the extent, or severity. Howev- er 3 cases(1.3%) of toxic megacolon appeared in moderate or severe extensive colitis, one of which progressed to perforation. Two cases(0.8%) of mortality were noticed, one caused by perforation, the other by operation related complication. There was not a single case of colon cancer developed during follow up period. Most cases showed excellent short term response to medical treatment; the symptomatic remission rates were 90.3%, 85.7%, 72.9% and 58.9% in order of proctitis, distal, left and extensive colitis, and the endoscopic remission rates were 78.8%, 50.0%, 59.1% and 30.0% respectively. Higher remission rates corresponded with lower extent of the disease. According to the severity, the symptomatic remission rates of milder dis- ease were significantly higher. The cumulative relapse rates were 38.7% in 1 year, 62.4% in 2 years, 73.3% in 3 years and 81.9% in 5 years, which were not related to the extent but in- creased according to the severity. The cumulative operation rates were 5.0% in 1 year, 7.6% in 2 years, 10.2% in 3 years and 15.9% in 6 years. The emergency operation accounted for only 22.2% of all operation and the others were elective ones. The most frequent indication of surgery was medical intractability which was determined after mean 35 days of intensive med- ical therapy. We concluded that severity and extent of ulcerative colitis had predictive value of the responses to medical treatment or relapses, furthermore despite the high relapse rates, medical therapy was the first line treatment because of its high remission rates on a short- term base.

        Clinical Experiences and Usefulness of Cervical Posterior Stabilization with Polyaxial Screw-Rod System

        Hwang, In-Chang,Kang, Dong-Ho,Han, Jong-Woo,Park, In-Sung,Lee, Chul-Hee,Park, Sun-Young The Korean Neurosurgical Society 2007 Journal of Korean neurosurgical society Vol.42 No.4

        Objective : The objective of this study is to investigate the safety, surgical efficacy, and advantages of a polyaxial screw-rod system for posterior occipitocervicothoracic arthrodesis. Methods : Charts and radiographs of 32 patients who underwent posterior cervical fixation between October 2004 and February 2006 were retrospectively reviewed. Posterior cervical polyaxial screw-rod fixation was applied on the cervical spine and/or upper thoracic spine. The surgical indication was fracture or dislocation in 18, C1-2 ligamentous injury with trauma in 5, atlantoaxial instability by rheumatoid arthritis (RA) or diffuse idiopathic skeletal hyperostosis (DISH) in 4, cervical spondylosis with myelopathy in 4, and spinal metastatic tumor in 1. The patients were followed up and evaluated based on their clinical status and radiographs at 1, 3, 6 months and 1 year after surgery. Results : A total of 189 screws were implanted in 32 patients. Fixation was carried out over an average of 3.3 spinal segment (range, 2 to 7). The mean follow-up interval was 20.2 months. This system allowed for screw placement in the occiput, C1 lateral mass, C2 pars, C3-7 lateral masses, as well as the lower cervical and upper thoracic pedicles. Satisfactory bony fusion and reduction were achieved and confirmed in postoperative flexion-extension lateral radiographs and computed tomography (CT) scans in all cases. Revision surgery was required in two cases due to deep wound infection. One case needed a skin graft due to necrotic change. There was one case of kyphotic change due to adjacent segmental degeneration. There were no other complications, such as cord or vertebral artery injury, cerebrospinal fluid leak, screw malposition or back-out, or implant failure, and there were no cases of postoperative radiculopathy due to foraminal stenosis. Conclusion : Posterior cervical stabilization with a polyaxial screw-rod system is a safe and reliable technique that appears to offer several advantages over existing methods. Further biomechanical testings and clinical experiences are needed in order to determine the true benefits of this procedure.

        Combination of Vitamin C and Rutin on Neuropathy and Lung Damage of Diabetes Mellitus Rats

        Sohn, Uy-Dong,Je, Hyun-Dong,Shin, Chang-Yell,Park, Sun-Young,Yim, Sung-Hyuk,Kum, Chan,Huh, In-Hoi,Kim, Jin -Hak The Pharmaceutical Society of Korea 2002 Archives of Pharmacal Research Vol.25 No.2

        We investigated the role of vitamin C or rutin on neuropathy and lung damage of diabetic mellitus(DM) rats. Norepinephrine content was significantly decreased in sciatic nerves of DM rats compared with non-DM controls but vitamin C had no effect on decreases of norepinephrine. 2,4-dinitrophenylhydrazine (DNPH) incorporation, which is biomarker of protein oxidation, was increased in sciatic nerve of DM rats as compared with normal control. However, vitamin C had no effects on increases of DNPH incorporation . We measured the content of conjugated dienes (CD) as a biomarker of lipid oxidation in sciatic nerve. CD was increased in DM as compared with normal control, Vitamin C or rutin had no effects on increases of CD. However, Rutin plus vitamin C significantly decreased the content of CD as compared with CIM rats. In lung of DM rats, DNPH incorporation or CD was increased as compared with normal control. Vitamin C or Rutin had no effects on increases of CD However, Rutin plus vitamin C significantly decreased the content of DNPH incorporation or CD in lung tissue. Vitamin C caused marked pathological changes such as the increases of parenchyma and the thickening of alveolar septa in the lung of DM. Rutin had protective effects on the pathological changes in the lung of DM rats. In conclusion, Vitamin C had no effects on oxidative parameter, such as DNPH incorporation or CD, and on the decreases of norepinephrine content in DM rats. Vitamin C caused the marked pathological changes in the lung of DM rats but rutin had protective efforts against the pathological changes.

        Hematologic and hemodynamic findings during hemodialysis in 13 beagle dogs

        Chang-Moo Ji, Hae-Won Jung, Hyo-Mi Jang, Jong-Hyun Moon, Dong-In Jung 충북대학교 동물의학연구소 2014 Journal of Biomedical and Translational Research Vol.15 No.2

        Hemodialysis is an effective therapy for renal failure in veterinary practice. To evaluate hematologic and hemodynamic changes during hemodialysis, 13 dogs were treated with hemodialysis, after which complete blood cell counts (CBC), serum chemistry, and mean systolic blood pressure were analyzed. For CBC, white blood cells (WBC) and platelets underwent significant changes. In serum chemistry, there were significant differences in blood urea nitrogen (BUN), creatinine, total protein, albumin, globulin, amylase, calcium, potassium, and phosphorus contents. Further, mean systolic blood pressure suddenly increased in early hemodialysis and decreased significantly thereafter. During hemodialysis, adverse effects were observed in some dogs as follows: bleeding (1 dog), anemia (2 dogs), leukopenia (8 dogs), thrombocytopenia (2 dogs), and hypotension (1 dog). This study demonstrates hematologic and hemodynamic effects during hemodialysis as well as complications similar to human medicine. Before applying the commercialized human hemodialysis system to canine renal failure patients, we monitored hematologic and hemodynamic findings during hemodialysis in healthy beagle dogs.

        VARIATION OF 24-HOUR INTRAOCULAR PRESSURE IN SILICONE OIL–FILLED EYES

        Chang, Joo Hyun,Shin, Jae Pil,Kim, In Taek,Park, Dong Ho Lippincott 2016 Retina Vol.36 No.1

        <P>Purpose:To evaluate the variation of 24-hour intraocular pressure (IOP) in silicone oil (SO)-filled eyes.Methods:Prospective, nonrandomized comparative case series of 42 eyes of 21 patients, each with an SO-filled eye after vitrectomy. The fellow eyes served as controls. Each subject slept the usual 8 hours, and IOPs were measured at 4-hour intervals over 24 hours, twice before sleep (5:30 and 9:30 pm), twice during sleep (1:30 and 5:30 am), and twice after sleep (9.30 am and 1:30 pm). Intraocular pressure was measured in the sitting position using a Goldmann applanation tonometer. The SO-filled eyes and fellow eyes were compared with respect to diurnal-to-nocturnal and nocturnal-to-diurnal IOP changes.Results:At all 6 time points, SO-filled eyes had higher mean IOPs than fellow eyes (all P < 0.05). For both groups, mean nocturnal IOP was higher than mean diurnal IOP (both P < 0.001). Changes in diurnal-to-nocturnal IOP and nocturnal-to-diurnal IOP between SO-filled eyes and fellow eyes did not differ significantly (P > 0.05, respectively). The peak IOP occurred in the nocturnal period for all fellow eyes and for 94.7% of SO-filled eyes.Conclusion:The IOP of SO-filled eyes varied over a 24-hour period, peaking largely in the nocturnal period, as observed for the IOP of fellow eyes.</P>

        고창순(Chang Soon Koh),이명철(Myung Chul Lee),정준기(June Key Chung),이동수(Dong Soo Lee),최창운(Chang Woon Choi),배상균(Sang Kyun Bae),양형인(Hyung In Yang),여정석(Jeong Suk Yeo) 대한핵의학회 1993 핵의학 분자영상 Vol.27 No.2

        N/A Dipyridamole is an agent that may be used to noninvasively evaluate coronary artery disease. The effect of dipyridamole infusion its generally related to its induced peripheral vasodilatory effect. In normal person, heart rate is generally increased slightly while blood pressure decrease, but the achieved double product and related myocardial oxygen consumption have no significant change. The purpose of this study is to examine the effect and side effect of dipyridamole, and to compare different response to dipyridamole among the patients. We evaluated 847 patients who underwent dipyridamole stress myocardial SPECT. 93.6% of them had induced hypotension 0.9% showed no change of blood pressure, 5.5% had increased blood pressure 8.3% had no change of pulse rate more than 10% of basal pulse rate. Among diabetes, 16.9% was not change of pulse rate, 6.7% in non-diabetes. There was no significant correlation between age and rate pressure product rest(RPPr), in patients without perfusion defects on SPECT(y=7.1x+48.4r=0.13 p>0.01). As increasing age, RPPs/RPPr was declined(y=-11.6x+68.9 r=0.17 p〈0.01), similar results were obtained in patients with perfusion defect. The size of perfusion defect on myocardial SPECT have no correlation between RPPr and RPPs/RPPr. The side effects of dipyridamole included chest pain and chest tightness, headache, abdominal pain, dizzness, nausea, and dyspnea. As increasing age, dipyridamole-induced cardiac work at rest was increased, cardiac response to dipyridamole was decreased.

        For the investigation of the physical growth of Korean Middle School Boys, the strature, span, lengths of upper and lower extremities, and body weight of 5,566 boys ranging from I2 to I5 years of age, and calculated the correlation coefficients among all of the items in each age group. The following conclusions have been obtained. 1. The average statures are 147.13 cm in 12 years of a8e, 161.90 cm in 15 years of age, and the annual growth I^∽ 4.92 cm. 2. The average spans are 145.69cm in 12 years of age, 162.07 cm in 15 years of age, and the annual growth is 5.46cm. 3. The average 1engths of upper extremity are 65.26 cm in 12 years of age. 72.20 cm in 15 years of age, and the annual growth is 2.31cm. 4. The average lengths of lower extremity are 81.71 cm in 12 years of age, 89.27 cm in 15 years of age, and the annual growth is 2.52cm. 5. The average body weights are 38.69 kg in 12 years of age, 51. 44 kg In 15 years of age, and the annual growth is 4.25 kg. 6. As a whole, the stature lengths of upper and lower extremities and body weight grow most speedly between 14 and 15 years of age groups. 7 The correlation coefficients between stature vs. span, lengths of upper and lower extremities, and span vs. lengths of upper and lower extremities are over than 0.8, representing very high. 8. The correlation coefficients among upper vs. lower extremity lengths, and body weight vs. stature, span, lengths of upper and lower extremities are over than 0.6, representing relatively high. 9. Above mentioned all of the correlation coefficients show to decrease with increasing age, but the correlation coefficients between lengths of upper and lower extremities show no differencies with increasing age. 10. The regression equations among all of the items in each age group are fabled for reference.
