Penetrating autokeratoplasty for optical has seldom been reported in recent literature. The patien presented here is a male, aged 31, farmer, who had a dense extensive corneal scar in his right eye. Keratoplasty, 6.5mm in disc diameter. 8 edge-to-edge direct sutures, postoperative beta-radiation, had been performed eventlessly on July 15. 1964 and postoperative reaction was minimum. The visual acuity improved from counting finger 30cm to 0.1 of Landolt's broken ring chart after 4 months of follow up observation. Minimum postoperative complication makes authors postulate autoplasty is relatively safe procedure.

OBJECTIVES: The purpose of this study was to investigate the deficits in executive function in children with ADHD and anxiety disorder, and further, to characterize executive function deficits among the two groups. METHODS: Subjects consisted of 60 children between the ages of 5 and 14 (16 Normal, 24 ADHD, 20 Anxiety Disorder). Neuropsychological tests (KEDI-WISC, CCTT, STROOP, WCST, ROCF) for assessing cognitive and executive function were individually administered to all subjects. RESULTS: There were no significant differences in FSIQ or PIQ among the three groups. However, the ADHD group tended to score lower on the VIQ and subtest of similarity, vocabulary, and digit span tests. The three groups did not significantly differ with respect to CCTT test results. On the STROOP test, the ADHD group showed poor performance on the word, color, and color-word subtests. The three groups did not exhibit significant differences in WCST test results ; however, the anxiety group performed poorly belonging to below 25 percentile rank on perseverative response. On the ROCF test, the ADHD group performed poorly with respect to their organization score and in particular, regarding copy and immediate recall. The anxiety group also performed poorly with regard to organization ; however, this was limited only to immediate recall. CONCLUSION: Children with ADHD displayed poor inhibition and organizational abilities compared to children with anxiety and normal controls. Further, children with anxiety disorder exhibited low cognitive flexibility and voluntary problem-solving abilities compared to ADHD children and normal controls. Based on these results, we suggest that the characteristics of executive dysfunction in ADHD and anxiety disorder in children are different.

The purpose of this study was to evaluate importance and performance of dietitian's task at long term care hospitals foodservices in the Busan.Kyongnam area. The research was performed through using questionnaires and conducted from June 11 to July 16, 2010 for 186 dietitians at 141 long-term care hospitals. Seventy-two percent of hospitals had two dietitians and 69% of them had a dietitian's office. Fifty-two percent of dietitians has worked for less than 2 years at long term care hospital, and 37.1% of them worked additional tasks. Seventy-three percent of hospitals conducted a therapeutic diet program and the therapeutic diets frequently provided were diabetic diet > tube feeding diet > dysphasia diet > sodium controlled diet. Mean score for the importance (4.36/5.00) and performance (3.91/5.00) of dietitian's tasks were significantly different (p < 0.001). The importance and performance grid showed that the purchase-inspection management and sanitation-safety management were high scores to the importance and performance (doing great area), menu-foodservice management and cooking-working management were low scores to the importance and high scores to the importance (overdone area), and nutrition management was low scores to the importance and performance (low priority). Forty-three percent of dietitians agreed with the needs for role separation between foodservice dietitian and clinical dietitian.

Purpose: Poloxamer-407 (P-407) is used to induce hyperlipidemia. Exercise is effective in improving arteriosclerosis and cognitive impairment. In this research, the effect of treadmill running on short-term memory in the P-407-treated hyperlipidemia rats was studied focusing on neuroinflammation. Methods: Rats were classified in normal group, normal and treadmill exercise group, P-407-treated group, and P-407-treated and treadmill exercise group. Hyperlipidemia rats were made by single intraperitoneal injection with P-407 (500 mg/kg). Treadmill exercise was conducted for 30 minutes once a day, 5 days per week during 28 days. Step-down avoidance task was done to measure short-term memory. Glial fibrillary acidic protein and ionized calcium binding adaptor molecule 1 were assessed by immunohistochemistry. Expression of adhesion molecules and proinflammatory cytokines was determined by western blot analysis. Results: Treadmill exercise alleviated lipid profiles in the P-407-induced hyperlipidemia rats. Treadmill exercise improved short-term memory, inhibited reactive astrogliosis and microglia activation, and suppressed expression of adhesion molecules and proinflammatory cytokines in the hyperlipidemic rats. Conclusions Treadmill exercise exerts alleviating effect on memory deficits by inhibiting hippocampal neuroinflammation in the hyperlipidemia. The current results suggest that treadmill running serves as the treatment strategy for the cognitive dysfunction caused by hyperlipidemia.

PURPOSE: The purpose of this study was to compare the validity of three fall risk assessment scales including the Morse Fall Scale (MFS), the Bobath Memorial Hospital Fall Risk Assessment Scale (BMFRAS), and the Johns Hopkins Hospital Fall Risk Assessment Tool (JHFRAT). METHODS: This study was a prospective validation cohort study in five acute care hospitals in Seoul and Gyeonggi-Do, Korea. In total, 356 patients over the age of 18 years admitted from December 2009 to February 2010 participated. The three fall risk assessment scales listed above were tested for sensitivity, specificity, positive predictive and negative predictive values. A receiver-operating characteristic (ROC) curve was generated to show sensitivities and specificities for predicting falls based on different threshold scores for considering patients at high risk. RESULTS: Based on the mean scores of each scale for falls, the MFS at a cut-off score of 50 had a sensitivity of 78.9%, specificity of 55.8%, positive predictive value of 30.8%, and negative predictive value of 91.4%, which were the highest values among the three fall assessment scales. Areas under the curve of the ROC curves were .761 for the MFS, .715 for the BMFRAS, and .708 for the JHFRAT. CONCLUSIONS: Accordingly, of the three fall risk assessment scales, the highest predictive validity for identifying patients at high risk for falls was achieved by the MFS.

Purpose: Thrombotic stroke is a type of ischemic stroke characterized by motor dysfunction and memory impairments. In the present study, the effect of treadmill exercise on motor function and short-term memory was evaluated in relation with synaptic plasticity in the mice with photothrombotic stroke. Methods: Photothrombotic stroke was induced by cortical photothrombotic vascular occlusion. The mice in the treadmill exercise groups performed running on a motorized treadmill for 28 days. Motor function was determined using rota-rod test and foot fault test. Step-through avoidance task was conducted to evaluate short-term memory. Immunohistochemistry for 5-bromo-2′-deoxyuridine and doublecortin was conducted to detect new cell generation. Postsynaptic density protein 95, synaptophysin, brain-derived neurotrophic factor (BDNF), and tyrosine kinase B receptor (TrkB) were determined using western blot. The number of dendritic spines was determined using Golgi stain. Results: Treadmill exercise improved motor function and short-term memory in mice with the photothrombotic stroke. The infarct size was reduced and the number of dendritic spines and expression of postsynaptic density protein 95 and synaptophysin in the peri-infarct cortex and hippocampus were increased by treadmill exercise in photothrombotic stroke mice. Treadmill exercise enhanced neurogenesis through increasing the expression of the hippocampal BDNF and TrkB in photothrombotic stroke mice. Conclusions Treadmill exercise improved motor function and short-term memory through increasing synaptic plasticity and neurogenesis in photothrombotic stroke mice. Treadmill exercise can be used as an effective treatment strategy to improve brain function related to stroke.

PURPOSE: Hyperlipidemia, which promotes the development of atherosclerosis, ischemic stroke, and other forms of brain injury, can be induced by poloxamer-407. Berberine is a primary pharmacological active component of Coptidis Rhizoma that has a number of therapeutic activities. This study investigated the effects of berberine on poloxamer-407-induced brain inflammation by evaluating its effects on short-term memory, cell proliferation, inflammation, and apoptosis in the hippocampus. METHODS: To induce hyperlipidemia in a rat model, 500 mg/kg of poloxamer-407 was injected intraperitoneally. Berberine was orally administered to the rats in the berberine-treated groups once a day for 4 weeks. The step-down task avoidance task was performed to measure short-term memory. An analysis of serum lipids, immunohistochemistry for 5-bromo-2′-deoxyuridine, glial fibrillary acidic protein (GFAP), and ionized calcium-binding adapter molecule 1 (Iba1) in the dentate gyrus, and western blot analysis for Bax, Bcl-2, and cytochrome c in the hippocampus were performed. RESULTS: In hyperlipidemic rats, berberine reduced the levels of triglycerides, total cholesterol, and low-density lipoprotein cholesterol and increased the level of high-density lipoprotein cholesterol in hyperlipidemic rats. Berberine also increased cell proliferation and short-term memory, as well as decreasing the expression of GFAP, Iba1, Bax, and cytochrome c and increasing Bcl-2 expression. CONCLUSIONS Berberine treatment improved short-term memory in hyperlipidemia by increasing neuronal proliferation and inhibiting neuronal apoptosis. Berberine treatment also improved lipid metabolism.

PURPOSE: The overactive bladder (OAB) syndrome is characterized by urgency usually with frequency and nocturia. Tamsulosin, alpha1-adrenergic receptor antagonist, is widely used to reduce symptoms of urinary obstruction and prostatic hyperplasia. Tamsulosin can across the blood-brain barrier. We investigated the effects of tamsulosin on the symptoms of OAB in relation to neuronal activity using rats. METHODS: Adult female Sprague-Dawley rats, weighing 250+/-10 g (9 weeks old), were used in this study. The animals were divided into five groups (n=8 in each group): control group, OAB-induced group, OAB-induced and 0.01 mg/kg tamsulosin-treated group, OAB-induced and 0.1 mg/kg tamsulosin-treated group, and OAB-induced and 1 mg/kg tamsulosin-treated group. OAB was induced by intraperitoneal injection of cyclophosphamide (75 mg/kg) every third day for 10 days. The rats in the tamsulosin-treated groups orally received tamsulosin once a day for 14 consecutive days at the respective dose of the groups, starting 1 day after the induction of OAB. Cystometry for bladder pressure determination, immunohistochemistry for c-Fos, nicotinamide adenine dinucleotide phosphate-diaphorase histochemistry for nitric oxide synthase (NOS) in the neuronal voiding centers and western blot for inducible NOS in the bladder were conducted. RESULTS: Cyclophosphamide injection enhanced contraction pressure and time, representing the induction of OAB. Contraction pressure and time were significantly suppressed by tamsulosin treatment. c-Fos and NOS expressions in the neuronal voiding centers were enhanced by induction of OAB. OAB-induced c-Fos and NOS expressions were suppressed by tamsulosin treatment. CONCLUSIONS: Tamsulosin exerts inhibitory effect on neuronal activation in the neuronal voiding centers of OAB. The present results suggest the possibility that tamsulosin is effective therapeutic modality for ameliorating the symptoms of OAB.

Fitz-Hugh-Curtis (FHC) syndrome is hepatitis characterized by severe right upper abdominal pain associated with pelvic inflammatory disease (PID), mimicking the symptoms of acute abdomen, such as in acute cholecystitis. FHC syndrome is becoming more common with the increasing incidence of PID in Korea. We treated eight patients with FHC syndrome, who visited our hospital with right upper quadrant abdominal pain. We emphasize the importance of spiral computed tomography (CT) in the diagnosis of right upper quadrant abdominal pain in sexually active young women.

PURPOSE: Cyclosporine A (CsA) is a potent immunosuppressive agent, and it has been used to prevent rejection of transplanted organs and to treat autoimmune diseases. Many side effects of CsA, including various types of endothelial dysfunction, have been reported. Pentoxifylline (PTX) is a non-selective phosphodiesterase inhibitor that is used for the treatment of peripheral vascular diseases. METHODS: We investigated the effect of CsA on collagen synthesis and clarified whether PTX has protective effects against CsA-induced arterial vasculopathy using calf pulmonary artery endothelial cells. This study was carried out using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, reverse transcription- polymerase chain reaction (RT-PCR), Western blot analysis, nitric oxide (NO) detection, and cyclic guanosine monophosphate (cGMP) enzyme immunoassay. RESULTS: CsA treatment significantly increased the expression of collagen type I mRNA and protein and decreased the production of NO and cGMP. However, pre-treatment with PTX exerted anticollagen effect by suppressing the CsA-induced formation of collagen, but this effect of PTX was not modulated by NO and cGMP. CONCLUSION: Based on the present results, it is expected that PTX may have a protective effect against CsA-induced arterial vasculopathy, although the mechanism of PTX needs to be clarified in future studies.
