PURPOSE: The purpose of this study was to assess chemotherapy induced peripheral neuropathy (CIPN) and to examine the relationship between CIPN and depression. METHODS: A purposive sample of 105 patients treated with chemotherapy were recruited in the cross-sectional survey design. Data were collected using self-report questionnaires. The instruments used were the Chemotherapy Induced Peripheral Neuropathy Assessment Tool (CIPNAT) and Hospital Anxiety Depression Scale (HADS). RESULTS: The most frequent suffering symptom of CIPN was 'tingling feeling in the hand and foot'. Of the motor symptoms, 'muscle weakness' was the most frequent symptom and 'muscle or joint aches' was the strongest suffering symptom of CIPN. The mean score for suffering of CIPN was 4.1. The mean score was 1.04 for depression and the prevalence was 48.5%. CIPN was significantly positively correlated with depression (r=.38, p<.001). The result of simple regression analysis revealed that CIPN was predictive of depression (R2=.136, p<.001). CONCLUSION: Based on the findings of this study, nursing intervention programs focusing on CIPN management and alleviating depression are recommended.

Journal of the Korean Pediatric Society 1997;40(6):786-793
PURPOSE: In order to elucidate the neurotoxic mechanism of oxygen radicals which are pathological factor of ischemia, we evaluated the oxidant-induced neurotoxicity and the neuroprotective effect of antioxidant on cultured cerebral neurons derived from neonatal mouse. METHODS: Neurotoxic effect was investigated after cultured mouse neuronal cells were exposed to oxygen radicals which were generated enzymatically by reaction of xanthine oxidase (XO) and hypoxanthine (HX). And also the neuroprotective effect of antioxidant was assessed with catalase. Both effects determined by cell viability were assessesd by MTT assay and neurofilament enzymeimmuno assay (EIA). In order to see the histologic change microscopic exam also done on the cerebral neuronal cells. RESULTS: 1) Oxygen radicals were toxic on cultured mouse cerebral neurons in dose- and time-dependent manner. 2) The value of lethal concentration50 (LC50) of oxygen radicals was estimated at a concentration of 25mU/ml xanthine oxidase (XO) and 0.2mM hypoxanthine (HX) in these culture. 3) Catalase was effective in blocking the neurotoxicity induced by oxygen radicals at a concentration of 50ug/ml. 4) Oxygen radicals induced the decrease of cell number and the loss of neurites in cultured mouse cerebral neurons. CONCLUSION: It is suggest that oxygen radicals cause the neurotoxicity and the selective antioxidants such as catalase are very effective in blocking oxidant-mediated neurotoxicity on cultured cerebral neurons of neonatal mouse.

Inflammatory mediators, such as oxidants, TNF-alpha, and IL-6, play a major role in the systemic response to bum injury It has been known that a continuing inflammatory response cause a sepsis and subsequent multiple organ failure. Recent studies have shown that burn patients receiving recombinant human growth hormone(rhGH) therapy have an improvement of the general condition, but the mechanism by which rhGH exerts its effects has not been clearly understood. The aim of this study was to evaluate the effect of rhGH on the early bum injury. Female Sprague-Dawley rats were divided into four groups : control group, bum group, burn plus rhGH treated group, and rhGH only treated group. Animals were killed at 30min., 3, 6, 24, and 48 hours after treatment. Histology and biochemical changes including malondialdehyde(MDA) content, tissue reduced glutathione(GSH) and catalase activity in the lung and liver, and plasma TNF-alpha and IL-6 levels were examined. Lung histology in the bum plus rhGH treated group showed decreased inflammtory response such as neutrophil and lymphocyte infiltrations, interstitial thickening, and edema compared with the bum group. Liver histology in the bum group revealed mild neutrophil and lymphocyte infiltrations, vacuolization .of hepatocytes, disrupted lobular structures, and dilated sinusoids. But liver histology of the bum plus rhGH was similar to control group. Lung and liver MDA in the burn plus rhGH and rhGH only treated groups were decreased with time compared with the burn group. Lung and liver GSH and catalase activities in the bum plus rhGH and GH only treated groups remained significantly increased compared with the bum group for the 48-hours period. Plasma TNF-alpha levels in the bum group remained elevated for the 48-hours period compared with the bum plus rhGH and rhGH only treated groups. Plasma IL-6 levels in the burn group were significantly increased only at first compared with the bum plus rhGH and rhGH only treated groups. These results suggested that rhGH showed inhibitory effects on the inflammatory cell infiltration and lipid peroxidation in the lung and liver after bum injury. Increased GSH levels and catalase activities seemed to be associated with the antioxidant effect of rhGH. But the inhibitory effect of rhGH on plasma TNF- and R-6 levels was not clearly demonstrated.

PURPOSE: To evaluate neurotoxic effects induced by oxygen-radicals, which were generated by adding xanthine oxidase(XO) and hypoxanthine(HX), and protective effects of glutamate receptor antagonist such as MK-801 and 6-cyano-7-nitroquinoxaline(CNQX). METHODS: Dissociated cell cultures were prepared from cerebrum of neonatal mouse. Tissues were dissected and diced into small pieces in phosphate buffered saline and were incubated at 37degrees C. Isolated cells were resuspended in Eagle's minimum essential medium and plated poly-L-lysine coated plastic coverslips in 96 well multichambers at a cell density of 3x105 cells/well. Cells were grown in a 5% CO2/95% air atmosphere at 37degrees C. Cytotoxic effects were examined in cerebral cortical neurons cultured for 3 hours in media containing various concentration of XO and HX. The protective effects of glutamate receptor antagonist were also examined by MTT assay and neurofilament enzymeimmunoassay(EIA). Microscopic examinations were also done. RESULTS: Oxygen radicals markedly induced decrement of the cell viability of cultured mouse cerebral cortical neurons in a dose-dependent manner. Midpoint cytotoxicity value was 30mU/ml XO/0.1mM HX, when mouse cerebral cortical neurons were incubated for 3 hours with various concentrations of XO and HX. The number of cells and neurites was decreased when cerebral cortical neurons were cultured for 3 hours in a medium containing 30mU/ml XO/0.1mM HX. MK- 801 was very effective in blocking oxidant-induced neurotoxicity, while CNQX falied to show any protective effect in these cultures. CONCLUSION: It is suggested that oxygen radicals are neurotoxic, and selective N-methyl-D-aspartate antagonists such as MK-801 are very effective in protecting neurotoxicity induced by oxygen radicals in cultured cerebral cortical neurons of neonatal mouse.

Core decompression is still widely used in avascular necrosis of the femoral head but the results are unpredictable and the indications are not settled yet. The reparative process of the decompressed femoral head is poorly understood. Seven cases in 5 patients were undertaken THRA following failed decompression and these were studied for the radiological and pathological changes of the core tracts. The lesions of failed cases were involved more than 1/3 of femoral head on MRI and all cases were stage II A or B. The extent of the necrotic area in MRI was enlarged with crack, sclerosis and sometimes gas collection. Depression of the subchondral plates were also observed. Capillary ingrowth or neovascularization was not found at all and there were only fibrosis, inflammatory response and foreign body reactions.

Most proximal humeral fractures respond satisfactorily to conservative treatment. It is only the occasional displaced fracture or fracture-dislocation that demaads special treatment. The purpose of this study is to analysis the results of closed and open reduction of displaced proximal humeral fractures according to Neers classification. Fifty-two cases of these fractures, followed up more than five months, are presented. 1. The average age of patients was 40. I years. 2. The fractures were classified according to Neers method. Nearly half (48.1%) of the cases were one-part fractures. Next, two-part fractures rated 42.3%, while three-part fractures, only one (l.9%). 3. Among the total 52 patients, 42 cases(80.8%) were treated conservatively and 10 were operated. We performed surgical operations in seven cases among 22 two-part fractures, aix were reduced with Kirschner wires and one treated with Kirschner wire and staple. The average age of these seven cases was 26. 6 years and the resulta were good except one. 4. The results of these patients were evaluated by the Neers criteria. Of 52 caaes, 40 had good results, five, fair, and the remaining seven poor results. Twenty-three cases (92%) in 25(100%) one-part fractures were good and 17 cases (77.3%) in 22 (100%) two-part fractures were also good. In three-part and four-part fractures the results were all poor.

Tailgut cysts in retrorectal or presacral space are rare and the derivatives of the embryonic post-anal gut. It is thought to arise from vestiges of embryonic hindgut. The lesions were usually multicystic and lined by a variety of epithelial types, including ciliated columnar, mucin-secreting columnar, transitional, and squamous epithelium. Tailgut cyst has been found in men and women of various ages but is more common in women and is usually associated with middle age. They may be the source of the chronic perirectal symptoms and rarely undergo malignant change, so early diagnosis and accurate evaluation is important. Complete surgical resection should be considered because of a long term risk of malignant change. We report two cases of tailgut cyst.

PURPOSE: The aim of this study is to prove the association between potential fetal hypoxia and retinopathy of prematurity (ROP) development and absolute nucleated red blood cell (aNRBC) is used to evaluate it in premature infants without any hypoxic or ischemic history. METHODS: Medical records of 43 premature infants with ROP who were admitted to the neonatal intensive care unit at Wonkwang University Hospital from January 2004 to December 2014 were analyzed retrospectively. We excluded 15 infants who had a confounding medical condition that could have increased the aNRBC count. Finally, 28 premature infants affected by ROP were enrolled and compared with 28 pair-matched controls. The aNRBC counts at birth in these infants were compared. Statistical analysis was performed with a paired t-test for continuous data, and a Fisher's exact test for categorical data. P<0.05 was considered significant. RESULTS: There were no significant differences in perinatal characteristics such as gestational age (GA), birth weight (BWt), Apgar scores, premature rupture of membrane (>24 hours), prenatal betamethasone, surfactant or respiratory distress syndrome between the ROP and the control infants. In addition, neither group differed in major morbidities such as patent ductus arteriosus, periventricular leukomalacia, intraventricular hemorrhage (> or =Grade 2), or bronchopulmonary dysplasia. Regardless of the severity of ROP, the aNRBC counts at birth in premature infants with ROP were not higher than in the control infants. CONCLUSION: The aNRBC counts at birth may not be related directly to the development of ROP.

We reviewed the medical records of patients with acute retinal artery obstruction (RAO) and evaluated the importance of transthoracic echocardiography (TTE) and carotid Doppler ultrasound in determining causes of cardiac and carotid artery origin in RAO. A retrospective case study conducted in the Department of Ophthalmology, Inha University Hospital, Korea comprised 26 patients presenting with acute RAO who underwent systemic evaluation, TTE and carotid Doppler ultrasound between June 1, 1997 and December 31, 2003. Among these 26 patients, abnormal cardiac findings were detected in 12 (46%) and abnormal carotid findings in 4 (15%). Furthermore, other risk factors for RAO were found in 2 (8%) and stroke broke out within 7 months after experiencing RAO in 4 (15%) of the 26 patients. In patients with acute RAO, TTE and carotid Doppler ultrasound play an important role in pinpointing the origins of retinal emboli. It is thought that TTE and carotid Doppler ultrasound may be essential examinations for determining the underlying cause, planning treatment strategies, and preventing stroke and death.
