The aim of this study was to investigate the quality changes of retort pouched seasoned-conger eel products during a 60 day of storage at 4, 15 and -20$^{\circ}C$. The seasoned-conger eel products was sterilized at either 100 or 121$^{\circ}C$ for 90min., and then vacuum packed in plastic film bags. When comparing their duality before and after sterilization, the pH and VBN of all the products slightly decreased, while the TBA values slightly increased after sterilization. The color value, b, of the product decreased after sterilization, while the L value rarely changed. During storage the pH and VBN of all the products were little changed at the storage temperatures of 15 and -20$^{\circ}C$. The TBA values increased after 30 and 60 days at 15$^{\circ}C$, and at 4 and -20$^{\circ}C$, respectively. As for color difference during storage, the L and a values were little changed during storage, while the b value increased. In conclusion, the quality of the retort pouched seasoned-conger eel products remained good during the 60 day storage period when chilled and frozen after sterilization, and could be consumed as an instant food, keeping an appropriate content and soft texture.

Cyclosporin A(CsA) is a selective immunosuppressive agent that has been credited with improved survival of solid organ allografts. Lymph node of BALB/C mouse administered CsA immunohistochemically observed to understand immunosuppressive effects of CsA on T lymphocytes, IL-2 receptors, and natural killer NK cells in lymph node. CsA orally administered daily for 10days at the dose 45mg/kg/day/. The lymph node were obtained at day 3, 7, and 14 after CsA administration and embedded with paraffin, and then stained by following ABC method that used monoclonal antibody including L3T4(CD4), Ly2(CD8), IL-2R(CD25), and NK-1.1(CD56). There were little changes of reactive degree and number of helper T lymphocytes, cytotoxic T lymphocytes, IL-2 receptors, and NK cells at day 3 after CsA administration, but they began to decrease at day 7. These decrease were greatest at day 14. The helper T lymphocytes. cytotoxic T lymphocytes, IL-2 receptors, and NK cells distributed in paracortex and medullary sinus. These results indicated that the secretion of IL-2 began to decrease at day 7 after CsA administration and subsequently to suppress T lymphocytes and NK cell as components of cell-mediated immunity.

Purpose: We investigated the natural history of acute, isolated posterior cruciate ligament injuries treated conservatively. Materials and Methods: Between February 1999 and October 2006, we evaluated retrospectively the results of acute, isolated posterior cruciate ligament injuries treated conservatively. The subjects consisted of 21 patients. At initial and follow up visits physical examination, $KT-2000^{TM}$ arthrometer and MRI were performed to assess improvement on the knee stability and continuity of the posterior cruciate ligament. IKDC (International Knee Documentation Committee) knee scoring and quadriceps muscle strength were also checked in all population. Comparing the results of initial and follow up examinations we assessed the natural history of acute, isolated posterior cruciate ligament injuries treated conservatively. The mean follow up period was 22.7 months. Results: The posterior drawer test showed 14 cases of Grade I, 6 cases of Grade II and 1 case of Grade III progressing 18 cases of Grade I and 3 cases of Grade II. The mean difference of 5.7mm by $KT-2000^{TM}$ arthrometer was changed Into 2.7mm and the continuity of posterior cruciate ligament initially checked by 48.1% on MRI increased to 69.7%. The mean quadriceps muscle strength was grade 'Good' and mean IKDC knee score was nearly grade 'A'. Conclusion: Our study suggests that patients with acute, isolated posterior cruciate ligament injuries treated conservatively may get good clinical outcomes on clinical situation and MRI.

Purpose: Symptoms of idiopathic Parkinson's disease (PD) include tremors, bradykinesia, and rigidity. The purpose was to explore the effects of breathing, meditation and qigong on the improving of insight, behavior, mood discomfort, depression, anxiety, and olfactory dysfunction, which are PD non-motor symptoms. Methods: Three stages of An's-4444 healing breathing, An's Gwanjeong healing meditation, and healing qigong performed 12 times for 80 minutes at a time in subjects with PD (11 patients), and pre- and post-measurements compared and evaluated. Results: The Integrated Parkinson's Rating Scale (UPDRSI) for mood discomfort after 12 healings was 69%. The Depression Scale (61%) for HAMD, and 64% for Anxiety (HAMA)), and the smell identification test (TSI) for a trial for olfactory dysfunction, improved to 82%, respectively. However, the numerical values after one month after 12 healing were almost same in all four scales. This means that the healing effect maintained until after one month. Conclusions: An's healing breathing, meditation and qigong therapy significantly improved insight, behavior, and mood discomfort, and non-motor symptoms such as depression, anxiety, and olfactory dysfunction. These results suggest that An's breathing, meditation and qigong therapy are valuable as a primary therapy to improve and heal non-motor symptoms in Parkinson's disease patients. Further research in biomedical science is needed.

Purpose : Bacillus Calmette-$Gu\acute{e}rin$(BCG) lymphadenitis is one of the most common complications of BCG vaccination. The involved lymph nodes usually subside spontaneously, but they may become enlarged and form an abscess. Treatment of these infants is controversial. The Pan American Health Organization recommends local isoniazid or rifampicin instillation for patients with suppurative BCG lymphadenitis. Methods : The study group comprised 37 patients who presented with BCG lymphadenitis over the last three years. BCG lymphadenitis was diagnosed if the affected patient developed an ipsilateral axillary or supraclavicular lymphadenitis, with no other identifiable cause for the lymphadenitis. We used rifampicin instillation therapy for patients with suppurative BCG lymphadenitis. Results : Lymphadenitis regressed spontaneously in three patients. Thirty four patients showed a progression to abscess formation. Among 34 patients with suppurative lymphadenitis, drainage developed spontaneously during the follow-up period in nine patients before therapy. Twenty five patients received needle aspiration and local rifampicin instillation therapy. Reaspiration was performed in seven patients. One of these patients still has large lymph nodes after the second attempt. Conclusion : Needle aspiration and local rifampicin instillation therapy into the node is a safe and effective form of treatment for suppurative BCG lymphadenitis.

Background: Off-pump coronary artery bypass grafting (OPCAB) has shown better outcome in chronic renal failure (CRF) patients by avoiding the effects of cardiopulmonary bypass. We evaluated renal function after OPCAB in CRF patients. Material and Method: 656 patients underwent OPCAB between January, 2001 and December, 2004. Data were collected in 26 CRF patients (Cr > 1.7 mg/dL). Preoperative/postoperative creatinine (Cr) levels, creatinine clearance and postoperative data were evaluated. We divided the patients into group 1 (Cr < 3 mg/dL) and group 2 (Cr $\geq$ 3 mg/dL). Result: Three patients started dialysis after surgery. Preoperative mean creatinine level (4.19$\pm$3.4 mg/dL) was elevated to 4.36$\pm$2.7 mg/dL at the third postoperative day and decreased below Preoperative level at the fifth postoperative day. In group 1 (mean Cr level=1.87$\pm$0.25 mg/dL), Cr level reached its peak level of 2.19$\pm$0.52 mg/dL at the fourth postoperative day (p=0.017), with subsequent decrease. Patients without pre- or postoperative dialysis (n=15) showed peak Cr elevation on postoperative day four (p=0.017) and subsequent decrease (p=0.01). Postoperative creatinine clearance showed reverse correlation with creatinine level. Conclusion: Creatinine level was elevated at third/fourth postoperative day, but decreased 5 days after surgery. Thus, if urgent dialysis is not indicated, postoperative renal replacement therapy in CRF patients may be better to be considered after four days observation.

Purpose : Hydronephrosis constitutes a great portion of fetal anomalies screened by prenatal sonogram. The present authors made an attempt to access its natural courses through follow up neonatal hydronephrosis diagnosed by prenatal sonogram. Methods : The study was composed of 23 neonates(36 renal units) who were diagnosed with hydronephrosis through prenatal sonogram screening and confirmed 3-7 days after birth with sonographic evaluation at Kyung Hee University Hospital. The neonates were closely monitored for 12-24 months with renal sonogram, diuretic renogram, intravenous pyelography(IVP) and voiding cystoureterography(VCUG). Results : The underlying diseases were composed of 16 cases(44%) of functional abnormalities, 14 cases(39%) of ureteropelvic junction(UPJ) obstruction, three cases(8%) of vesicoureteral reflux (VUR) and on case each of multicystic dysplastic kidney, UPJ obstruction with ureteral stenosis and ureterovesical junction(UVJ) obstruction with VUR. The degree of hydronephrosis was divided into three classes according to its severity. In 30 renal units with UPJ obstruction and functional abnormalities, 26(87%) showed mild hydronephrosis, while four(13%) were moderate. During the follow up period, six cases(20%) showed natural resolution of hydronephrosis, 15 cases(50%) showed improvement while two cases(7%) were aggravated with improvement only after surgery of the underlying disease. The cases which showed natural resolution were all mild hydronephrosis at diagnosis and the cases which underwent surgery due to continuous aggravation were mild one case and moderate one case. Conclusion : Those with cases of mild hydronephrosis show rapid natural improvement. On the other hand, in some cases, follow up monitoring reveal aggravation of the situation, emphasizing the necessity for thorough follow up for a long period of time.

초기 시대부터 로마의 힘과 영광은 어떠한 잠재적인 적에 비교해도기술 및 효과면에서 비교되지 않을 정도였던 군사제도의 탁월함에서 기인하였다. 로마 제국 초기 3세기 반 동안에 군사제도의 여러 가지 면에서 다양한 변화가 있었다. 그러한 변화 중 일부는 시간의 경과에 따른 자연스러운 것이었고, 또 일부의 변화들은 내부적인 긴장과 갈등 때문에 비롯되었고, 또 다른 변화들은 외부의 적으로부터 고무된 것이었다. 로마 군사 제도의 우월성과 그에 따른 제국의 계속된 영광은 로마인의 실제적인 문제들에대한 실용적 및 논리적인 접근태도에 많은 부분 기인하였다.
