사료내 Zeolite 첨가가 비육돈의 생산성과 도체특성에 미치는 영향

J. H. Kim*, S. C. Kim** and Y. D. Ko**Korea Applied Microorganism Industrial Research*,College of Agriculture and Life Science, Gyeongsang National University**ABSTRACTThis study was conducted to investigate the effect of dietary supplementation of zeolite on growth performance,carcass characteristics and fecal ammonia gas release in the finishing pigs. A total of 120 crossbred finishingpigs (50.2±1.4kg, Landrace×Yorkshire×Duroc) were assigned to 4 treatments and randomly divided into 12groups. They were divided between early finishing period (50~80kg) and late finishing period (80~120kg).Finishing pigs were fed on a basal diet supplemented with 0, 1, 2 and 4% levels of zeolite. Average daily gainand feed conversion were significantly (P<0.05) improved by the dietary supplementation of 4% zeolite comparedwith other treatments during overall period. In the finishing periods, ammonia gas emission was reduced (P<0.05) in 4% zeolite treatment more than that of the other treatments. Carcass weight and back fat thicknesseswere not affected by zeolite treatments. But, the appearance of A grade pork was increased by the dietarysupplementation of 4% zeolite. Feed cost was linearly decreased by increasing the supplementation of zeolite.According to this study, 4% supplement of zeolite is suitable for the improvement of carcass quality and feedconversion, the reduction of fecal ammonia gas emission and feed cost per body weight gain.(Keywords : Zeolite, Finishing pig, Performance, Carcass characteristic, Ammonia gas)

Insulation Test of Reciprocal and Concentric Winding Arrangement for a HTS Transformer

In Korea, the Hyosung Industrial, Korea Polytechnic University and Gyeongsang National University are developing a power distribution and transmission class HTS transformer that is one of the 21st century superconducting frontier projects. For the development, it is necessary to establish the dielectric technology at cryogenic temperature such as insulating design, cooling system, manufacture, compact, and so on. Also, verification of insulating stability is an important dielectric technology. Therefore, we prepared two models, one is concentric arrangement, the other is reciprocal arrangement, from Kapton insulated Cu tape for a small simulated HTS transformer and measured their insulation characteristics such as PD, ac (50 kV, 1 min) and impulse (154 kV, 1.2/spl times/50 /spl mu/s) withstand test. Before manufacture of each model, we have analyzed insulation composition and investigated electrical characteristics such as breakdown of LN/sub 2/, polymer and surface flashover on FRP in LN/sub 2/. We are going to compare with measured each value and apply the value to most suitable insulating design of the HTS transformer.

An unusual presenting feature of precursor T-cell acute lymphoblastic leukemia/lymphoma

Precursor T-acute lymphoblastic leukemia/lymphoma (ALL) comprises approximately 20–25% of adult cases of ALL. Precursor T-ALL tends to present in adolescent males as lymphomas and is characteristically presented with a high leukocyte count or large mediastinal mass at initial presentation. We report here a rare manifestation of precursor T-ALL presenting with clinically significant involvement of ovary and spine at initial presentation. A 33-year-old woman presented with low abdominal pain and lumbago for 1 day in July 2004. Physical examination revealed tenderness in the right lower abdominal region. No enlarged spleen, liver or lymph nodes was palpable. Hematologic data showed Hb level of 8.3 g/dl, 8.91×10/l of WBC with 87% of segmented neutrophils, 10% of lymphocytes, 3% of monocytes, and 328×10/l of platelets. An ultrasound examination of the pelvis revealed a cystic mass with a dimension of 6.5×4.5 cm in the right ovary. An emergent operation was performed for presumed symptomatic ovarian cyst. Ovarian masses were solid masses rather than cystic masses under the laparotomy, and right salpingooophorectomy with left ovary wedge resection was done. Histologic examination of the ovarian masses revealed lymphoblastic infiltration (Fig. 1a). They showed positive immunoreactivity for CD3 (cytoplasmic pattern), CD10 and CD45 (leukocyte common antigen) and negative immunoreactivity for CD20, CD30, CD117 and CD68. On the fourth postoperative day the patient developed abrupt-onset paraplegia and sensory loss of both lower extremities. Magnetic resonance imaging of the spine showed a dorsal epidural mass destroying from T9 to T12, and multiple enhancing lesions in L3, L4, S1 vertebral body were revealed (Fig. 1b). Emergency operative decompression of the spinal cord was done to relieve the lower extremity paraplegia. Autogenous iliac bone graft and from T7 to T12 posterolateral fusion following T9, 10, 11 total and T8 partial decompressive laminectomy was done after the removal of epidural mass. Histologic examination of the spinal mass revealed lymphoblastic and eosinophilic infiltration (Fig. 1c). The lymphoblasts were characterized by positive immunoreactivity for CD3 (cytoplasmic pattern), CD10 and CD45 (leukocyte common antigen) and negative immunoreactivity for CD20, CD30, CD117 and CD68. Under the impression of T lymphoblastic lymphoma, bone marrow examination was done. The bone marrow touch imprint preparation showed that 92% of marrow cells were lymphoblasts. They were variable in size and characterized by high nuclear–cytoplasmic ratio (Fig. 1d). Trephine biopsy showed diffuse infiltration of marrow by lymphoblasts, which revealed numerous mitotic figures (Fig. 1e). Immunohistochemical stain showed positive reactivity for CD3 (cytoplasmic pattern) and negative for CD20 (Fig. 1f). Chromosomal analysis of bone marrow demonstrated a 46XX karyotype in 100% (20/20) of the cells. A CT scan of the chest demonstrated an anterior mediastinal mass approximately 12×8 cm. A diagnosis of precursor T-ALL was made. The patient was started on induction chemotherapy with vincristine, prednisone, daunorubicin and L-asparaginase (VPDL). The anterior mediastinal mass regressed substantially and revealed a focal streaky density on followup chest CT checked on 28 June 2004. In August 2004, remission was successfully achieved as shown by follow-up bone marrow examination. The patient subsequently received further consolidation VPDL therapy and currently remains in good health. Precursor T-ALL is associated with numerous unfavorable presenting features; thus, patients have a worse prognosis than patients with precursor B-ALL. In adults, higher white blood cell counts (>30,000/μl) and older age (>60 years) shorten durations of remissions and overall survival M.-A. Kim (*) . K.-Y.

Usefulness of Troponin-I, Lactate, C-reactive protein as a Prognostic Markers in Critically Ill Non-cardiac Patients

Background : The severity scoring system is useful for predicting the outcome of critically ill patients. However, the system is quite complicated and cost-ineffective. Simple serologic markers have been proposed to predict the outcome, which include troponin-I, lactate and C-reactive protein(CRP). The aim of this study was to evaluate the prognostic values of troponin-I, lactate and CRP in critically ill non-cardiac patients. Methods : From September 2003 to June 2004, 139 patients(Age: , M:F = 88:51), who were admitted to the MICU with non-cardiac critical illness at Gyeongsang National University Hospital, were enrolled in this study. This study evaluated the severity of the illness and the multi-organ failure score (Acute Physiologic and Chronic Health EvaluationII, Simplified Acute Physiologic ScoreII and Sequential Organ Failure Assessment) and measured the troponin-I, lactate and CRP within 24 hours after admission in the MICU. Each value in the survivors and non-survivors was compared at the 10th and 30th day after ICU admission. The mortality rate was compared at 10th and 30th day in normal and abnormal group. In addition, the correlations between each value and the severity score were assessed. Results : There were significantly higher troponin-I and CRP levels, not lactate, in the non-survivors than in the survivors at 10th day(, vs. , ) (p, , vs. , , ) (p, 0.365, p

Atypical Lymphocytic Lobular Panniculitis in Korea: Frequent Expression of Epstein – Barr Virus

Although subcutaneous T‐cell lymphoma is considered an aggressive form of lymphoma, some patients manifest a long waxing and waning phase unaccompanied by constitutional symptoms. Magro et al (2004) applied the term “atypical lymphocytic lobular panniculitis (ALLP)” to this distinctive form of lymphocytic panniculitis. Eight ALLP patients (five females and three males, mean age: 34.0 ± 12.5) were encountered from Jun 1999 to Nov 2003 at GyeongSang National University Hospital in Korea. Five patients (62.5%) had skin lesions only and oral prednisone therapies were done. Two of five had no relapse but three showed a waxing and waning course till now. In three patients (37.5%) presenting cytopenias and fevers, chemotherapies were done with prednisone, cyclophosphamide, vincristine, doxorubicine, bleomycin and/or adriamycin. Two of three led to complete resolution till now and included only one patient with clonal T‐cell receptor‐gamma rearrangements. In seven patients, serum EBV antibody studies were performed. Six of them suggested EBV reactivation state and one was asymptomatic EBV carrier. In three patients, tissues EBV ISH were done and all were positive to EBER and lytic probe.

Usefulness of Cardiac Troponin I as a Prognostic Marker in Non-cardiac Critically Ill Patients

Background : Cardiac troponin I (cTnI) is a specific marker of myocardial injury. It is known that a higher level of cTnI is associated with a poor clinical outcome in patients with acute coronary syndrome. An elevation in cTnI is also observed in various noncardiac critical illnesses. This study evaluated whether cTnI is useful for predicting the prognosis in noncardiac critically ill patients. Methods : From June 2003 to July 2004 at Gyeongsang National University Hospital, we enrolled 215 patients (male:142, female:73, mean age: years ) who were admitted for critical illness other than acute coronary syndrome at the medical intensive care unit(ICU). The severity score of critical illness (SAPS II and SOFA) was determined and serum cTnI level was measured within 24 hours after admission to the ICU. The mortality rate was compared between the cTnI-positive () and cTnI-negative () patients at the and day after admission to the ICU. The mean cTnI value was compared between the survivors and non-survivors at the and day after admission to the ICU in the cTnI-positive patients. The correlation between cTnI and the severity of the critical illness score (SAPS II and SOFA) was also analyzed in cTnI-positive patients. Results : 1) The number of cTnI-negative and positive patients were 95(44%) and 120(56%), respectively. 2) The mortality rate at the and day after admission to the ICU was significantly higher in the cTnI-positive patients (29%, 41%) than in the cTnI-negative patients (12%, 21%)(p and day after admission to the ICU was significantly higher in the non-survivors (, ) than in the survivors(, ) (p

The Distribution Pattern of Lymphocyte Subsets according to the Level of Serum Albumin in Preoperative Patients with Gastric Cancer

Purpose: Considering that nutritional state correlates to immunity, we performed this study to evaluate the correlation by assessing the numerical changes of the levels of serum albumin and lymphocyte subsets. Materials and Methods: The study was performed on patients who were diagnosed as having gastric cancer and who underwent curative surgery from August 1998 to August 2004 in the Gyeongsang National University Hospital and whose peripheral blood lymphocyte subsets were tested prior to surgery. The study population was a total of 150 cases. Results: The change in the lymphocyte subsets in relation to the change in the level of serum albumin in all patients with gastric cancer was determined, and was compared to disease stages. When patients were classified by using the level of serum albumin with 3.2 mg/dl as the cut-off point (low group: serum albumin 3.2 mg/dl), the number of peripheral blood lymphocytes, CD3+ cells, CD4+ cells, CD8+ cells, and CD16+ 56 cells were, significantly lower in the group with the level of serum albumin below 3.2 mg/dl (low group) than it was in the group with a serum albumin level above 3.2 mg/dl (normal group) (P

The Diagnostic Usefulness of Pleural Fluid Adenosine deaminase with Lymphocyte/Neutrophil Ratio in Tuberculous Pleural Effusion

Background : The measurement of adenosine deaminase(ADA) level in pleural fluid is useful in the diagnosis of tuberculous(TB) pleural effusion. However, ADA is also elevated in other diseases such as malignancy, bacterial infections, empyema, and collagen vascular disease, ADA alone has limited value. The object of this study is to determine diagnostic usefulness of the combined use of ADA value with lymphocyte/neutrophil ratio(L/N ratio) rather than the use of ADA alone. Method : We evaluated 198 patients(age=55.9±12.9, M/F=2.7:1) with pleural effusion who had admitted in Gyeong󰠀 sang National University Hospital from Jan. 1999 to Dec. 2001. retrospectively. Patients were divided into four diagnostic groups: TB pleural effusion(n=91), parapneumonic effusion(n=65), malignant effusion(n=21), and transudative effusion(n=13). The ADA level, differential cell count, biochemistry, cytology, and microbiology of each diagnostic groups were evaluated. The sensitivity, specificity, negative predictive value(npv), positive predictive value(ppv) and efficiency were calculated at each ADA values and combined ADA value with various L/N ratios. Results : The ADA level in TB pleural effusion was significantly higher than that of parapneumonic effusion, malignant pleural effusion, and transudative effusion(p<0.05). Sensitivity, specificity, ppv, npv and efficiency at ADA ≧50 IU/L in the diagnosis of TB pleural effusion were 89.0%, 82.2%, 81.0%, 89.8% and 85.5% respectively. When ADA≧50 IU/L was combined with lymphocyte/neutrophil ratio≧0.75, sensitivity, specificity, ppv, npv, and efficiency were 83.5%, 96.3%, 95.0%, 87.9% and 90.5% respectively. Specificity, ppv and efficiency were increased with combination of ADA value and L/N ratio. Conclusion : Combination of ADA value and L/N ratio in pleural effusion is more useful than ADA value alone in the diagnosis of TB pleural effusion. (Tuberc Respir Dis 2004; 57:132-137)

Clinical Features in Patients with Amylase-Rich Pleural Effusion

Background : Pleural effusions with high amylase levels are reported frequently in patients with pancreatic diseases, a rupture of the esophagus and a malignancy. However, there is no data available on the clinical features of an amylase-rich pleural effusion in Korea. This report describes the causes of the high amylase levels in a pleural effusion and analyzes its association with malignancy. Methods : The records of patients with an amylase-rich pleural effusion who were assessed at the Gyeongsang National University Hospital from January 1998 to August 2002 were examined retrospectively, and the distribution of amylase levels in those patients, the causative diseases, and the histological type in the case of a malignancy were analyzed. Among the 532 patients whose pleural effusion was evident on a chest X-ray, there were 36 cases with an amylase-rich pleural effusion. The amylase levels were determined by an enzyme method (Hitach 747 autoanalyzer). Results : Of the 36 patients with an amylase-rich pleural effusion, there were 18 patients(50%) associated with a malignancy, 8 patients(22%) with a parapneumonic effusion, 7 patients(19%) with pancreatic disease, and 3 patients with other causes. The amylase level in a pleural effusion due to pancreatic disease was much higher than that due to other causes(p<0.01). Among the malignant pleural effusions with high amylase levels, the origin of the malignancy was a primary lung cancer in 13 cases and metastatic lung cancer in 5 cases. The histological types of malignant causes were adenocarcinoma

Dairy-cattle health in Gyeongnam, Korea

An animal-health monitoring system in the Gyeongnam area was started in 1997 to develop statistically valid data for use in estimating disease frequencies in dairy cattle, and the associated costs. The objectives of this study were to: (1) describe what was done to implement and maintain the system in Gyeongnam; (2) present selected disease frequencies; (3) discuss the epidemiological consideration of what was done and implications for results obtained. Veterinary medical officers (VMOs), comprising professors and graduate students from Gyeongsang National University, faculty of Gyeongnam Livestock Promotion Institute and clinic veterinarians, served as data collectors. After training on current disease and management problems of dairy cattle, interview techniques, sampling methods and data-collection instruments, the VMOs participated in selection of the sample herds and data gathering. Forty ( n=40) of 167 dairy herds were selected randomly using a computer-generated list of random numbers and the VMOs visited farms once in a month for 12 months to collect data about management, disease, inventory, production, preventive treatment, financial and other relevant data. Strict data-quality control devices were used. Specific feed-back was developed for the producers and data collectors. The six disorders found most frequently in cows (from the highest to the lowest) were breeding problems, clinical mastitis, birth problems, gastrointestinal problems, metabolic problems and lameness. In young stock, respiratory, multiple system, breeding and gastrointestinal problems were predominant, whereas in calves, gastrointestinal, respiratory and integumental problems predominated.

STABILITY OF ITERATIVE PROCESSES WITH ERRORS FOR NONLINEAR EQUATIONS OF φ-STRONGLY ACCRETIVE TYPE OPERATORS

In this paper, we study the stability of the Mann and Ishikawa iterative processes with errors for the nonlinear equations of φ-strongly accretive type operators in arbitrary real Banach spaces. We also study the stability of the Mann and Ishikawa iterative processes with errors for the iterative approximation of fixed point of Lipschitzian and φ-hemicontractive operators in arbitrary real Banach spaces. †The second author was supported by '98 APEC Post-Doctor Fellowship (KOSEF) while he visited Gyeongsang National University and the third author wishes to acknowledge the financial support of the Korea Research Foundation Grant (KRF-99-005-D00003).

A Case of Pulmonary Cysticercosis

Cysticercosis, which has a worldwide distribution is found in man, who is usually infected by eating inadequately cooked pork or other contaminated food. Cysticercosis develops most commonly in the muscles and brain. Pulmonary involvement is very rare and also difficult to recognize because pulmonary lesions caused by the presence of cysticerci are difficult to discern from pulmonary infiltrates, because other parasitic infestations or tuberculosis, as well as metastatic lesions, produce similar chest X-ray findings and similar clinical symptoms.We experienced a case of pulmonary cysticercosis confirmed at Gyeongsang National University Hospital by means of an open lung biopsy and treated successfully with praziquantel (50 mg/kg per day for 15 days).This case seems to indicate that pulmonary cysticercosis should be considered as a diagnostic possibility in patients with nodular infiltrates in the lungs, especially in endemic areas, until such infiltrates are otherwise explained.
