Peripheral neurodegenerative diseases induced by irreversible peripheral nerve degeneration (PND), such as diabetic peripheral neuropathy, have a high prevalence worldwide and reduce the quality of life. However, there is no agent effective against the irreversible PND. After peripheral nerve injury, Schwann cells play an important role in regulating PND. However, because PND involves multiple biochemical events in Schwann cells, a one-drug-single-target therapeutic strategy is not feasible for PND. Here, we suggested that fascaplysin (Fas), a compound with multiple targets (CDK4/6), could overcome these problems. Fas exerted a significant inhibitory effect on axonal degradation, demyelination, and Schwann cell proliferation and dedifferentiation during in vitro and ex vivo PND. To discover the most likely novel target for PND, a chemo-bioinformatics analysis predicted the other on-targets of Fas and identified androgen receptor (AR) which were involved in Schwann cell differentiation and proliferation.AR interacted with Fas, and nuclear import of the AR/Fas complex was inhibited in Schwann cells, altering the expression patterns of transcription factors during PND. Therefore, Fas may have therapeutic potential for irreversible peripheral neurodegenerative diseases.

Although renal artery aneurysms (RAAs) rarely occur, rupture of RAAs may be life-threateningand result in nephrectomy. To date, there has been only one case report providing histologic evidence of a true aneurysm in a transplanted renal artery. We report here a 51-year-old male with a de novo trueaneurysm in a donor renal artery that was detected 12 years postoperatively. This RAA was corrected by ex vivo repair and allograft autotransplantation.

A 66-year-old male was admitted for increasing azotemia. He was diagnosed with chronic antibody- mediated rejection and had received a livingdonor renal transplant from his 32-year-old son prior to his admission. The peritubular capillaries of his kidney were diffusely positive on C4d immunostaining. It is known that there is an agreement between C4d staining and serological and histopathological data during rejection that is thought to have a humoral component. The role of alloantibodies in chronic renal allograft deterioration and the corresponding morphologic changes have been increasingly recognized during the recent years. However the treatment guidelines for chronic antibody-mediated rejection have not yet been established. Intravenous immunoglobulin (IVIG) has been shown to decrease the titers of anti-HLA antibodies in highly sensitized patients awaiting transplant. There are also numerous proposed mechanisms regarding how IVIG exerts its immunomodulatory action. As we have experienced chronic antibody-mediated rejection and how IVIG treatment improves renal function, we recognize that IVIG has the potential to be used for treating certain subgroups of chronic allograft nephropathy patients with positive C4d staining and anti-HLA antibodies.

PURPOSE: We aim to compare the erythropoietic effects of epoetin-alpha (EA, 4000 IU SC thrice a week) with those of darbepoetin-alpha (DA, 60ug IV weekly, conversion rate to EA=200:1). METHODS: Forty one stable hemodialysis patients were enrolled in this randomized crossover study. After a washout period of erythropoietin stimulating agents (ESA), the patients with hemoglobin (Hb) level of < or =11.0 g/dL were randomly assigned to DA or EA and we measured Hb and reticulocyte levels. When Hb reached >11.0 g/dL, we stopped ESA. When Hb level decreased to < or =11.0 g/dL again, we switched to alternative ESA and repeated the rest of the steps. RESULTS: Thirty six patients (M:F=20:16, age 62+/-11 years, Kt/V 1.65, nPCR 1.13 g/kg/day) completed the study. No significant differences were observed in baseline parameters between DA and EA during the period of the clinical trial. The rate of Hb level increase (EA 0.29 g/dL/week, DA 0.30 g/dL/week, p=0.76) and decrease (EA 0.45 g/dL/week, DA 0.38 g/dL/week, p=0.14) were not different between two periods. After ESA stopped, the duration of decreased Hb level of < or =11.0 g/dL was not significantly different (4 weeks in EA vs. 3.9 weeks in DA, p=0.86). Erythropoietin resistance index was 10.59 in the EA period. It was not significantly different from 10.97 in DA period (p=0.49). Nine patients (25%) showed a >30% change in EA efficiency relative to DA efficiency. CONCLUSION: There was no significant difference in erythropoietic parameters for both EA and DA.

Sirolimus is a promising immunosuppressive drug for renal transplantation to avoid nephrotoxicity of calcineurin inhibitor. However, it has been associated with uncommon but, important pulmonary toxicity. We present a case of sirolimus related dyspnea with abnormal chest radiographic finding in a 63 year old male renal transplantation recipient. There was no evidence of bacterial, fungal, or viral infection. Dose reduction of sirolimus resulted in a significant improvement of the symptoms and chest radiographic finding.

This study aims to help improving the quality of military food service as identifying awareness, attitudes and satisfaction of cooking soldier on their duties and providing basic data to find out alternatives on the basis of identified data. The analysis results are described as follows. For general demographics of subjects, sergeants consisted of the highest percentage of population as 38.8% in terms of the rank. For educational background, the percentage of graduates or college students was 82.5%. For the characteristics of job performance of cooking soldier, those who studied entirely different courses from cookery and became to work as cooking soldier were 92(89.3%) of total subjects. For the question why they became to work as cooking soldier, the response that they didn't know the reason showed the highest percentage as 63.1%. Those who selected cooking soldier because they were interested in cookery were only 25.2%. And 94.2% of the population had no certificates related to cookery. With respect to awareness on training period to carry on duties as cooking soldier, 3 months were selected as the most appropriate period as 36.9%. In accordance with research on job percentage of cooking soldier, 'cleaning and washing' consisted of the highest percentage among ordinary duties as 16.8%, followed by 'cooking' as 12.3% and 'food dispensing' as 11.8%. This study suggests as follows on the basis of the results of this researches. Cooking soldier requires expertise, but the privates with short period of service are discharged from military service when they are accustomed to their duties and become experts. Accordingly, the cooking soldier system could not achieve more than its ordinary performance. Therefore, it is required to post non-commissioned officers who can serve for a long time as the special resources.

PURPOSE: TATA box mutation/polymorphism in the promoter region of the bilirubin uridinediphosphoglucuronate glucuronosyltransferase 1A1 (UGT-1A1) gene is known to be an etiology of hyperbilirubinemia. This study examined if a TATA box mutation/polymorphism in UGT-1A1 gene promoter could be associated with the development of severe early neonatal jaundice in Korean infants. METHODS: Thirty-nine neonatal jaundice patients and 40 controlled infants were analyzed for UGT-1A1 promoter genotypes by using DNA sequencing. RESULTS: The homozygote for (TA)7TAA mutation was not found in this study. Comparison of the prevalence of UGT-1A1 promoter (TA)7TAA heterozygotes revealed no difference between the group with jaundice and the controlled group (15.4% vs. 10%). The peak bilirubin level was higher and the onset of jaundice was earlier in the jaundice group with (TA)7TAA heterozygote compared to the jaundice group without (TA)7TAA heterozygote (23.2+/-1.0 mg/dL vs. 19.7+/-2.4 mg/dL, P=0.004, 5.0+/-1.5 days vs. 8.3+/-4.1 days, P= 0.057). CONCLUSION: The results of this study showed that TATA box polymorphism in UGT-1A1 gene promoter did not increase the prevalence of severe early neonatal jaundice in Korean infants.
