Background: Orthotopic organ transplantation, a treatment option for irreversible organ dysfunction according to organ failure, severe damaged organ or malignancy in situ, was usually accompanied with massive blood loss thus transfusion was required. We aimed to evaluate the adverse impact of blood transfusion on solid organ transplantation. Materials and Methods: From January, 2009 to December, 2014, patients who received orthotopic organ transplantation at Far Eastern Memorial Hospital medical center were enrolled. Clinical data regarding anemia status and red blood cell (RBC) transfusion before, during and after operation, as well as patient outcomes were collected for further univariate analysis. Results: A total of 105 patients who underwent orthotopic transplantation, including liver, kidney and small intestine were registered. The mean hemoglobin (Hb) level upon admission and before operation were $11.6{\pm}1.8g/dL$ and $11.7{\pm}1.7g/dL$, respectively; and the nadir Hb level post operation and the final Hb level before discharge were $8.3{\pm}1.6g/dL$ and $10.2{\pm}1.6g/dL$, respectively. The median units (interquartile range) of RBC transfusion in pre-operative, peri-operative and post-operative periods were 0 (0-0), 2 (0-12), and 2 (0-6) units, respectively. Furthermore, the median (interquartile range) length of hospital stay (LHS) from admission to discharge and from operation to discharge were 28 (17-44) and 24 (16-37) days, respectively. Both peri-operative and post-operative RBC transfusion were associated with longer LHS from admission to discharge and from operation to discharge. Furthermore, it increased the risk of post-operative septicemia. While peri-operative RBC transfusion elevated the risk of acute graft rejection in patients who received orthotopic transplantation. Conclusions: Worse outcome could be anticipated in those who had received massive RBC transfusion in transplantation operation. Hence, peri-operative RBC transfusion should be avoided as much as possible.

Background: Blocking angiogenesis by targeting vascular endothelial growth factor (VEGF) signaling pathway to inhibit tumor growth has proven to be successful in treating a variety of different metastatic tumor types, including kidney, colon, ovarian, and lung cancers, but its role in castration-resistant prostate cancer (CRPC) is still unknown. We here aimed to determine the efficacy and toxicities of anti-VEGF agents in patients with CRPC. Materials and Methods: The databases of PubMed, Web of Science and abstracts presented at the American Society of Clinical Oncology up to March 31, 2014 were searched for relevant articles. Pooled estimates of the objective response rate (ORR) and prostate-specific antigen (PSA) response rate (decline ${\geq}50%$) were calculated using the Comprehensive Meta-Analysis (version 2.2.064) software. Median weighted progression-free survival (PFS) and overall survival (OS) time for anti-VEGF monotherapy and anti-VEGF-based doublets were compared by two-sided Student's t test. Results: A total of 3,841 patients from 19 prospective studies (4 randomized controlled trials and 15 prospective nonrandomized cohort studies) were included for analysis. The pooled ORR was 12.4% with a higher response rate of 26.4% (95%CI, 13.6-44.9%) for anti-VEGF-based combinations vs. 6.7% (95%CI, 3.5-12.7%) for anti-VEGF alone (p=0.004). Similarly, the pooled PSA response rate was 32.4% with a higher PSA response rate of 52.8% (95%CI: 40.2-65.1%) for anti-VEGF-based combinations vs. 7.3% (95%CI, 3.6-14.2%) for anti-VEGF alone (p<0.001). Median PFS and OS were 6.9 and 22.1 months with weighted median PFS of 5.6 vs. 6.9 months (p<0.001) and weighted median OS of 13.1 vs. 22.1 months (p<0.001) for anti-VEGF monotherapy vs. anti-VEGF-based doublets. Conclusions: With available evidence, this pooled analysis indicates that anti-VEGF monotherapy has a modest effect in patients with CRPC, and clinical benefits gained from anti-VEGF-based doublets appear greater than anti-VEGF monotherapy.

Objective : This study was to review on the prostate disease-related studies with Acupuncture therapy in renowned medical internet site of PubMed, and to make master plan of the study, especially, on Bee Venom Acupuncture(BVA) of Prostate disease and then to devise the idealistic therapeutic ways of it. Method : We made the internet search with the key words of bee venom(bee venom therapy, apitoxin, apitherapy, bee sting, bee sting therapy), acupuncture, prostate, prostatitis, prostrate cancer in Pubmed, from June 1st to July 1st,2004. Results : 1.25 papers were found in 19 publised jounals. of which two named'Urology'and Prostate' had three papars, two called 'JUrology' and 'Cancer Immunol Immunother' had two papers, and the others had a paper respectively. 2. In the classification by papers' types, Review papers were 8 and Original were 17 where there were 5 clinical trials, 11 experimental studies and 1 epidemiologic paper. Of 5 clinical trials, 2 belonged to Randomized Control Study, and of 11 experimental studies, 4 belonged to in vitro and 7 belonged to in vivo with in viro studies, and 1 epidemeologic belonged to meta-analysis. 3. In the classification by prostate diseases, 4 were about prostatitis, 3 were about prostate related symptoms, 16 were about prostate cancer, and two were about the others. 4. In the classification by applied treatment methods, 5 were related with Acupuncture, 10 were related with BVA(Bee Venom, Bee), and 10 were related with the others. Of 5 related with Acupuncture, 3 used general acupuncture, 1 used electrical acupuncture, and 1 used general acupuncture and electrical acupuncture at the same time. 5. In 2 RCTs of Clinical trials, Control group was set up to the group using different compatible treatment method or using meridians not related with treating prostate disease. Single or double blind methods couldn't be found. 6. In the clinical trials, IPSS, NIH, CPSI or subjective global assessment were used as the Index of Evaluation. 7. The Leg Greater Yang Bladder Meridian(B), The Leg Lesser Um Kidney Meridian(K) and Conception Vessel Meridian(CV) were used as major meridians, and B10(Taejo, Dazhu), B23(Shinsu, Shenshu), B28(Panggwangsu, Pangguangshu), B35(Hoeyang, Huiyang), B39(Wiyang, Weiyang), B40(Wijung, Weizhong), B54(chilbyon, Zhibian), K1(Yongchon, Yongquan), K10(Umgok, Yingu), CV3(Chungguk, Zhongji), CV4(Kwanwon, Guanyuan),S6(Hyopko, Jiache) were used as acupoints. Electrical acupuncture(EA) was considered to be more important and CV3(Chungguk, Zhongji), CV4(Kwanwon, Guanyuan) were mainly selected as EA applied acupoints. 8. It is mostly said that Acupuncture appeared to be a safe, effective, and durable treatment alternative in improving symptoms of patients with prostate diseases, refractory to conventional medicine. A larger controlled study was required to confirm these encouraging initial results. Conclusion : Papers about BVA of Prostate cancer or Prostatitis were not found, and low permeability of Prostate is concerned, BVA with the anti-inflammatory and anti-cancer effect can be adopted as a new alternatives of Prostate disease treatment, so it is thought that Study of how to make access to prostate, animal experiment including in vivo and in vitro and more clinical trials with using acupoints on related meridian should be followed.

Background: Crocus sativus and its major constituent crocin are well established to have anti-cancer properties in breast cancer cells (MCF-7). However the role of C. sativus extract (CSE) and crocin on caspase signaling mediated MCF-7 cell death at molecular level is remains unclear. In this study, we tried to unravel role of CSE and crocin on caspase mediated MCF-7 cells death and their in vivo preclinical toxicity profiling and immune stimulatory effect. Materials and Methods: CSE extract was fractionated by HPLC and crocin was isolated and characterized by NMR, IR, and MS. MCF-7 cells were treated with both CSE and crocin and expression of Bcl-2 and Bax was assessed after 24 and 36 hours. Furthermore, caspase 3, caspase 8 and caspase 9 expression was determined by Western blotting after 24 hours of treatment. DNA fragmentation analysis was performed for genotoxicity of CSE and crocin in MCF-7 cells. The in vivo toxicity profile of CSE (300 mg/kg of b.wt) was investigated in normal Swiss albino mice. In addition, peritoneal macrophages were collected from crocin (1, 1.5 and 2 mg/kg body weight) treated mice and analyzed for ex vivo yeast phagocytosis. Results: Immunoblot analysis revealed that there was time dependent decline in anti-apoptotic Bcl-2 with simultaneous upregulation of Bax in CSE and crocin treated MCF-7 cells. Further CSE and crocin treatment downregulated caspase 8 and 9 and cleaved the caspase 3 after 24 hours. Both CSE and crocin elicited considerable DNA damage in MCF-7 cells at each concentration tested. In vivo toxicity profile by histological studies revealed no observable histopathologic differences in the liver, kidney, spleen, lungs and heart in CSE treated and untreated groups. Crocin treatment elicited significant dose and time dependent ex vivo yeast phagocytosis by peritoneal macrophages. Conclusions: Our study delineated involvement of pro-apoptotic and caspase mediated MCF-7 cell death by CSE and crocin at the molecular level accompanied with extensive DNA damage. Further we found that normal swiss albino mice can tolerate the maximum dose of CSE. Crocin enhanced ex vivo macrophage yeast phagocytic ability.

Sodium butyrate (SB) has various metabolic actions. However, its effect on dipeptidyl peptidase 4 (DPP-4) needs to be studied further. We aimed to evaluate the metabolic actions of SB, considering its physiologically relevant concentration. We evaluated the effect of SB on regulation of DPP-4 and its other metabolic actions, both in vitro (HepG2 cells and mouse mesangial cells) and in vivo (high fat diet [HFD]-induced obese mice). Ten-week HFD-induced obese C57BL/6J mice were subjected to SB treatment by adding SB to HFD which was maintained for an additional 16 weeks. In HepG2 cells, SB suppressed DPP-4 activity and expression at sub-molar concentrations, whereas it increased DPP-4 activity at a concentration of $1,000{\mu}M$. In HFD-induced obese mice, SB decreased blood glucose, serum levels of insulin and $IL-1{\beta}$, and DPP-4 activity, and suppressed the increase in body weight. On the contrary, various tissues including liver, kidney, and peripheral blood cells showed variable responses of DPP-4 to SB. Especially in the kidney, although DPP-4 activity was decreased by SB in HFD-induced obese mice, it caused an increase in mRNA expression of $TNF-{\alpha}$, IL-6, and $IL-1{\beta}$. The pro-inflammatory actions of SB in the kidney of HFD-induced obese mice were recapitulated by cultured mesangial cell experiments, in which SB stimulated the secretion of several cytokines from cells. Our results showed that SB has differential actions according to its treatment dose and the type of cells and tissues. Thus, further studies are required to evaluate its therapeutic relevance in metabolic diseases including diabetes and obesity.

방사선치료를 위한 CT 검사 시 동일 환자에 대하여 3차원영상과, 호흡주기영상을 획득하기 위한 컴퓨터단층촬영에서 환자의 피폭선량을 측정하고자 SOMATON SENSATION OPEN(SIEMENS, GERMANY)을 이용하여 내원환자 중 폐암환자 10명, 간암환자 10명의 CT 검사 시 피폭선량을 측정했다. 환자가 받는 피폭선량은 The volume CT dose index(CTDIvol), Dose Length Product(DLP)를 이용하여 분석하였으며 각각의 장기들이 받는 피폭선량의 실측은 환자의 장기를 대상으로 할 수 없어 Rando 팬텀을 이용 흉부검사 시 폐와 심장, 척수를, 복부검사 시 간과 신장의 위치를 선택하여 in-vitro와 in-vivo 계측이 가능한 광유도발광선량계(Optically Stimulated Luminescent Dosimeter, Landauer, Inc., USA)를 이용하여 측정하였다. 폐암환자의 CT 검사 시 10명의 CTDIvol값은 5.7배, DLP값은 약 2.4배, 간암환자의 CTDIvol값은 3.8배, DLP값은 약 1.6배의 값을 나타내었고, OSLD를 이용한 실측정치 역시 폐암환자의 경우 6배, 간암환자의 경우 5.5배의 차이를 보이는 등 4DCT 검사에서 전체적인 피폭선량의 증가를 볼 수 있었다. 방사선치료 시 호흡에 의한 치료부위의 위치변화를 4DCT 검사를 이용하여 움직임을 보정하여 치료계획시 치료용적의 정확성을 높일 수 있으나 4DCT 검사로 인한 환자의 피폭선량 증가를 고려하여 검사시간과 검사범위를 줄여 피폭선량을 감소시키기 위한 노력이 필요하다.

A new concept of "photo" -antisense method has been evaluated, where the inhibition of gene expression by the conventional antisense method is enhanced by photochemical binding between antisense oligonucleotides conjugated with photo-reactive compound and target mRNA or DNA. Fluorescein labeled oligodeoxyribonucleotides (F-DNA) was delivered to cell nuclei in the encapsulated form in multilamellar lecithin liposomes with neutral charge. F-DNA was previously shown to photo-bind to the complementary stranded DNA, and the delivery system using neutral liposome to be effective in normal human keratinocytes. In the present study, we used human kidney cancer G401.2/6TG.1 cell line to be advantageous in reproducible experiments. p53 was adopted as a target gene since antisense sequence information has been accumulated. The nuclear localization ofF-DNA was identified by comparing the fluorescence ofF-DNA with that of Hoechst 33258 under fluorescence microscope. After 7hr incubation to accumulate p53 protein induced by UV -B, p53 protein was quantified by Western blot. After 2hrs from F-DNA application, about 30% of cell population incorporated F-DNA in their nuclei with some morphological change possibly due to liposomal toxicity. Irradiation of visible light longer than 400nm from solar simulator at this time enhanced the inhibitory action of antisense F-DNA. The present results suggest that photo-antisense method is promising to control gene expression in time and space dependent manner. Further improvement of F-DNA delivery to cancer cells in the stability and toxicity is in progress. progress.
