A combination of process modification and various additives to a lime-based spray-dryer/fabric-filter system was evaluated for its value in promoting sorbent utilization and simultaneous removal of HC1 and SO₂ from waste incineration flue gas. The variety of operating conditions were tested to evaluate important factors such as spray drying reactor(SDR) outlet temperature, retention time, molar equivalence ratio( MER ), fabric filter velocity, etc. For the sorbent activity enhancement, additives such as KmnO₄, NaOH, NaHCO₃, CaCl₂, a mixture of NaOH and CaCl₂ were added to Ca(OH)₂ at optimum operating condition. The mixture of NaOH and CaCl₂ ( 2 : 1 by weight ) was found to be the best economic additive. When that additive, 10% of Ca(OH)₂ by weight, was added, under the condition of Ca(OH)₂ of MER 1.0, HCl/SO₂ removal efficiencies at fabric filter were 98.3% and 97.1%, respectively.

Background and Objectives: Intentional self-mutilation of the genitals in male is exceedingly rare. As the authors experienced 3 cases of male genital self-mutilation while psychotic, we investigated with psychiatric points of view including general and psychiatric characteristics of genital self-mutilation in Korea. Materials and Methods: Total 21 cases of the genital injury were obtained from the index book of Journal of Korean Neuropsychiatric Association and the Electronic Library Search Engine. From these, excluding the 4 accident-caused cases of penile amputation, the authors investigated 17 cases in terms of general epidemiological characteristics, the type of mutilation, diagnostic classification, psychodynamics of their behavior. Results: Epidemiological data showed that the most of the genital self-mutilation cases are twenties (52.9%); most are single (64.7%). In terms of the mutilation types, complete transection of penis type were committed most frequently (72.1%). The formal diagnoses were mainly schizophrenia (82.3%) and schizoid personality disorder(11.8%). Psychodynamically, lots of cases could be explained as to punish failures in the male role (20.6%), related to religiosity (14.7%), and related to physical pain or somatic illness (14.7%). Conclusion: We are unable to say exactly what prompts a man to divest himself of his genitals. On the basis of 17 cases, we are willing to hazard several risk factors. For individuals psychotic at the time of act there seem to be at least three paradigmatic at-risk groups: (1) younger acutely psychotic men with related to cure or punish failures in the male role, (2) the men with personality disorders who act rageful feelings against themselves and/or close objects, and (3) sociocultural factors known to contribute to such an act include some complex religious belief regarding purification or resisting temptation. Psychological factors yet undetermined may be' equally important.

This study has been carried out to investigate the removal efficiencies of HCl/SOx in a Spray-Dryer/Fabric-Filter system. In HCl/SOx removal, we could identify the key factors such as spray dryer outlet temperature, molar equivalence ratio(MER) and fabric filter velocity, but we couldn't find out the correlation of HCl and SOx. The removals of HCl/SOx were inversely proportional to spray dryer outlet temperature(l30~170℃) and filter velocity(l.0~1.5 m/min), at the MER, HCl removal efficiency was strongly proportional to MER, but SOx, removal efficiency was not particularly increased by MER over 1.5. The removal efficiencies of HCl/SOx were improved over 10% at the fabric filter. In this Spray-Dryer/Fabric-Filter system, HCl/SOx removal efficiencies were about 99%, 96% respectively.

목적 : 최근 8년간 본원에서 경험한 자기면역성 간염의 혈액학적 특징과 스테로이드의 치료효과를 알아보고자 본 연구를 시행하였다. 방법 : 1996년 이후부터 2002년까지 충남대학교 병원에서 1999년 International Autoimmune Hepatitis Group(LAHG)에서 제시한 수정 진단 기준안에 의거하여 총 진단점수가 probable 이상에 해당하는 환자들을 대상으로 임상적 특징, 검사실 및 조직 소견과 스테로이드와 azathioprine의 치료 효과를 후향적으로 조사하였다. 결과 : 9예의 환자들은 여성이 78%, 40대가 많았고, 급성 발병이 33.3%, 피로감, 식욕부진 및 황달 등이 나타났으며, 항핵항체가 55.6%에서 그리고 항평활근 항체가 77.8%에서 양성이었고, 동반 질환은 류마치스 관절염이 2예, 특발성 혈소판 감소증 1예, Henoch-Sch nlein 자반증 및 그레브스병이 각각 1예 씩이었다. 7예에 대해서 스테로이드와 azathioprine으로 치료하여 생화학적 임상적 완해가 이루어져서 유효한 치료 결과를 얻었다. 결론 : 자가면역성 간염은 우리 나라에서 원인을 찾을 수 없는 만성 간질환의 경우, 특히 중년여성에서 다른 자가면역성 질환이 동반되었을 때 자가면역성 간염을 의심하여 자가항체 선별검사를 시행해 보아야 할 것으로 생각된다. 향후 다기관 연구를 통하여 좀 더 많은 증례를 모으고 전향적인 연구를 시행하여야 할 필요가 있다. Although autoimmune hepatitis(AIH) is common in western contries, some studties have been reported in Korea. The aim of the study was to analyze the clinical and histological features and expression pattern of the autoantibody and to examine clinical course of AIH in Korea. For 9 patients diagnosed as having AIH in our hospital since 1996, we reviewed medical records and analyzed clinical and laboratory findings retrospectively. They had a probable or definite AIH according to the revised criteria of International AIH group. The mean age was 42.7(21∼68)years and 7(77.8%) were female. Three of them(33.3%) showed acute hepatitis and five of them showed cirrhosis. Fatigue and anorexia were the most frequently complained symptoms(55.6%). Four patients(44.4%) were accompanied with other autoimmune diseases. Antinuclear antibody was detected in 5(55.6%) and anti-smooth muscle antibody was detected in 7(77.8%). Three patients showed focal picemeal necrosis and four showed periportal fibrosis. Among 7 patients who received immunosuppressive therapy, six patients(85.7%) showed initial response. and biochemical and serologic remission were achived in 5(71.4%) and 3(42.8%) patients, AIH seems to be partly responsible for chronic liver disease of unknown etiology in Korea. AIH should be suspected in female patients with unknown chronic liver disease of unknown etiolgy, especially accompanied with other autoimmune disease. The clinical characteristics of AIH may not be quite different from those of Western countries.

Steroid cell tumor is a rare ovarian sex cord-stromal tumor which accounts for 0.1% of all ovarian tumors. Until now, only 4 cases have been reported in domestic literatures. Steroid cell tumor often secrets testosterone and presents virilization in adult women or precocious puberty in children. Treatment is often performed by surgical removal, adjuvant chemotherapy and radiation, but completely accepted treatment was not existed. We experienced a case of steroid cell tumor, which was manifested by typical virilization in a 43-year old patient, who was previously performed hysterectomy and unilateral oophorectomy. So, we present with a brief review of the literatures.

정윤영,선희매,김영택,김남훈,안계훈,장인엽,김종중,문정석,강양수 조선대학교 부설 의학연구소 1999 The Medical Journal of Chosun University Vol.24 No.1

The immunohistochemical (ABC method) studies on the ontogeny and localization of the catecholamine-synthesizing enzyme tyrosine hydroxylase (TH) were examined in rat brain from the 12th fetal day until the 9th postnatal day. The results obtained were as follows : 1. Tyrosine hydroxylase was first detected immunohistochemically at embryonic day 13(E13). At this stage, the TH-containing neurons were still migrating and cytologically immature. 2. The changes occuring from the early to the late prenatal stages of development appeared to be the result of an increase in the number and size of the TH-containing cells and in the length of nerve fibers. 3. The distribution of the TH-containing neurons at embryonic day 19(E19) more closely resembled catecholaminergic neurons in the adult rat brain : 1) a rhombencephalic group became the A1-7 ; 2) a ventral mesencephalic group became A8-10 ; 3) a ventral prosencephalic group and a few neurons ventral to the striatum became A11-14 ; and 4) the cells of the olfactory bulb corresponded to the A15. 4. The cytodifferentiation of the TH-immunoreactive neurons was accompanied by continued migration to form the collective catecholaminergic groups during ontogenesis. In addition, the morphology of the TH-immunoreactive neurons in the late prenatal stage resembled in the adult rat brain.

Is Pancapsular Release More Effective than Selective Capsular Release for the Treatment of Adhesive Capsulitis?

Nam Hoon Moon,Seung-Jun Lee,Won Chul Shin,Sang Min Lee,Kuen Tak Suh 대한견주관절의학회 2015 대한견주관절학회지 Vol.18 No.1

Background: We assessed the effectiveness of arthroscopic capsular release for the treatment of adhesive capsulitis. Further, we tried to ascertain the clinical benefits, if any, of pancapsular release over selective capsular release, where the two differ by performing or not performing a posterior capsular release, respectively. Methods: Thirty-five consecutive patients with either primary or secondary adhesive capsulitis who failed conservative treatment for more than 6 months were enrolled in the study. A total of 16 patients allocated in group 1 received a pancapsular release that comprises the release of the rotator interval, anteroinferior capsular, and the posterior capsular release, whereas 19 patients in group 2 received a selective capsular release that comprises only the release of the rotator interval release and anteroinferior capsular release. The clinical outcomes, visual analogue scale (VAS) score, Constant score, and range of motion, were assessed preoperative and postoperatively. Results: In both groups, the preoperative VAS score, Constant score, and ROM showed a significant improvement by the 6-month follow-up. We found that the immediate postoperative internal rotation was significantly higher in group 1 than group 2. Despite significant differences seen between the two groups at the initial postoperative period, there were no significant differences in Constant score, VAS score, and the ROM at all the subsequent follow-ups between the two groups. Conclusions: Arthroscopic capsular release for the treatment of adhesive capsulitis is very effective. However, pancapsular release did not show any advantage over selective capsular release in terms of overall clinical outcome.

Development of Multiplex RT-PCR for Simultaneous Detection of Garlic Viruses and the Incidence of Garlic Viral Disease in Garlic Genetic Resources

Nam, Moon,Lee, Yeong-Hoon,Park, Chung Youl,Lee, Min-A,Bae, Yang-Soo,Lim, Seungmo,Lee, Joong Hwan,Moon, Jae Sun,Lee, Su-Heon The Korean Society of Plant Pathology 2015 Plant Pathology Journal Vol.31 No.1

Garlic generally becomes coinfected with several types of viruses belonging to the Potyvirus, Carlavirus, and Allexivirus genera. These viruses produce characteristically similar symptoms, they cannot be easily identified by electron microscopy (EM) or immunological detection methods, and they are currently widespread around the world, thereby affecting crop yields and crop quality adversely. For the early and reliable detection of garlic viruses, virus-specific sets of primers, including species-specific and genus-specific primers were designed. To effectively detect the twelve different types of garlic viruses, primer mixtures were tested and divided into two independent sets for multiplex polymerase chain reaction (PCR). The multiplex PCR assays were able to detect specific targets up to the similar dilution series with monoplex reverse transcription (RT)-PCR. Seventy-two field samples collected by the Gyeongbuk Agricultural Technology Administration were analyzed by multiplex RT-PCR. All seventy two samples were infected with at least one virus, and the coinfection rate was 78%. We conclude that the simultaneous detection system developed in this study can effectively detect and differentiate mixed viral infections in garlic.
