  • Objective: To evaluate clinical efficacy of a dose escalating schedule of paclitaxel concurrent with radiotherapy in treating patients with locally advanced non-small cell lung (NSCLC). Methods: Patients with locally advanced NSCLC were treated with conventional fractionated radiotherapy or three dimensional conformal radiotherapy (3 DCRT), concurrently with a dose escalating schedule of paclitaxel. All patients were divided into three groups, A with paclitaxel $30mg/m^2$, B with paclitaxel $60mg/m^2$ and C with paclitaxel $90mg/m^2$. Paclitaxel was repeated every week for a total of 4 or 6 weeks. Results: Among 109 patients, response rates were 68.8%, 71.1% and 71.8% (p>0.05) for group A (n=32), B (n=38), and C (n=39) respectively. Accordingly, disease control rates were 81.3%, 81.6% and 82.1% (p>0.05). Progression-free survival time was $8.0{\pm}5.0$ months, $11.6{\pm}6.1$ months, and $14.8{\pm}7.9$ months (p<0.05), respectively. Overall survival time was $15.4{\pm}7.6$ months, $18.2{\pm}8.0$ months, and $22.0{\pm}7.6$ months (p<0.05), one-year survival rates were 62.5%, 73.1% and 90.0% (p>0.05) and two-year survival rates were 31.3%, 38.5% and 50.0% (p<0.05). Main side-effects were bone marrow suppression, radiation related esophagitis and gastrointestinal reaction. Conclusion: In treating patients with NSCLC, concurrent chemoradiotherapy with paclitaxel improves early response compared with conventional fractionated radiotherapy or 3 DCRT. The survival rate was improved with the addition of paclitaxel, but there was an increase in adverse reactions when the dose of paclitaxel was increased.

  • Objective: To investigate the effect of high expression of XAF1 in vivo or in vitro on lung cancer cell growth and apoptosis. Methods: 1. The A549 human lung cancer cell line was transfected with Ad5/F35 - XAF1, or Ad5/F35 - Null at the same multiplicity of infection (MOI); (hereinafter referred to as transient transfected cell strain); XAF1 gene mRNA and protein expression was detected by reverse transcription polymerase chain reaction (RT-PCR) and Western blotting respectively. 2. Methyl thiazolyl tetrazolium (MTT) and annexin V-FITC/PI double staining were used to detect cell proliferation and apoptosis before and after infection of Ad5/F35 - XAF1 with Western blotting for apoptosis related proteins, caspase 3, caspase - 8 and PARP. 3. After the XAF1 gene was transfected into lung cancer A549 cells by lentiviral vectors, and selected by screening with Blasticidin, reverse transcription polymerase chain reaction (RT-PCR) and Western blotting were applied to detect mRNA and protein expression, to establish a line with a stable high expression of XAF1 (hereinafter referred to as stable expression cell strain). Twenty nude mice were randomly divided into groups A and B, 10 in each group: A549/XAF1 stable expression cell strain was subcutaneously injected in group A, and A549/Ctrl stable cell line stable expression cell strain in group B (control group), to observe transplanted tumor growth in nude mice. Results: The mRNA and protein expression of XAF1 in A549 cells transfected by Ad5/F35 - XAF1 was significantly higher than in the control group. XAF1 mediated by adenovirus vector demonstrated a dose dependent inhibition of lung cancer cell proliferation and induction of apoptosis. This was accompanied by cleavage of caspase -3, -8, -9 and PARP, suggesting activation of intrinsic or extrinsic apoptotic pathways. A cell strain of lung cancer highly expressing XAF1 was established, and this demonstrated delayed tumor growth after transplantation in vivo. Conclusion: Adenovirus mediated XAF1 gene expression could inhibit proliferation and induce apoptosis in lung cancer cells in vitro; highly stable expression of XAF1 could also significantly inhibit the growth of transplanted tumors in nude mouse, with no obvious adverse reactions observed. Therefore, the XAF1 gene could become a new target for lung cancer treatment.

  • PURPOSE. This randomized clinical trial was conducted to assess the safety and effectiveness of the ErhBMP-2 in alveolar bone regeneration as well as preservation of the ${\beta}$-TCP bone graft material that contains ErhBMP-2. MATERIALS AND METHODS. This study involved 72 patients at the 3 study centers. The patients, who were divided into 2 groups: the experiment group who had ErhBMP-2 coated TCP/HA and the control group who had TCP/HA graft material alone transplanted immediately after tooth extraction. CT was taken before and 3 months after the transplantation and healing status was compared between the two groups. The efficacy endpoints that were used to measure the degree of bone induction included alveolar bone height and 3 measurements of bone width. The paired t test was used to determine the significance of the changes (P<.05). RESULTS. Changes in alveolar bone height were $-1.087{\pm}1.413$ mm in the control group and $-.059{\pm}0.960$ mm in the experimental group (P<.01). At 25% extraction socket length [ESL], the changes were $0.006{\pm}1.149$ mm in the control group and $1.279{\pm}1.387$ mm in the experimental group. At 50% ESL, the changes were $0.542{\pm}1.157$ mm and $1.239{\pm}1.249$ mm, respectively (P<.01 for 25% ESL, and P<.05 for 50% ESL). During the experiment, no adverse reactions to the graft material were observed. CONCLUSION. ErhBMP-2 coated ${\beta}$-TCP/HA were found to be more effective in preserving alveolar bone than conventional ${\beta}$-TCP/HA alloplastic bone graft materials.

  • 본 연구는 흑마늘을 기능성 화장품 소재로 활용하기 위하여 그 기능성을 in vitro에서 tyrosinase 및 elastase 저해 활성을 측정한 결과 피부노화에 관여하는 두 효소의 활성을 모두 저해하였다. 흑마늘 추출물을 hartley계 기니픽 수컷을 사용하여 피부 1차 자극 실험을 실시한 결과 1차 피부자극지수(P.I.I.)가 0.23으로 practically non-irritation(비자극성)에 해당하는 자극으로 피부 자극이 거의 없었음을 알 수 있었다. Maximization test법으로 피부 감작성을 확인한 결과 시험물질에 의한 홍반과 부종 등이 전혀 유발되지 않았다. 이상의 결과로부터 흑마늘 추출물에 대한 기니픽의 피부 감작율은 0%로, 피부에 대한 피부 감작성이 없는 것으로 확인되었다. 따라서 이러한 본 연구의 결과는 흑마늘 추출물이 기능성 화장품 소재로 피부노화를 억제하는 기능성과 안전성확보된 소재임을 추정할 수 있었다.

  • The purpose of the study was to explore the effect of 2 hour infusion of vancomycin(1g) in 200ml of isotonic saline every 12 hour on the frequency of "red man syndrome", phlebitis and length of peripheral catheter placement of infected patients, in order to provide safe infusion method for reducing vancomycinin-duced RMS and phlebitis. The subjects of the study consisted of 16 hospitalized patients; 3 oncology and gastro-intestinal patients, 1 neurological patient, 6 thoracic surgical patients and 6 orthopedic patients, who had received vancomycin from July to October in 1999 at S-hospital. The dependent variables were the incidence of RMS, phlebitis and the length of peripheral catheter placement. The incidence of RMS was checked by an inspector at the first night whenever the infusion method of vancomycin was changed. RMS was observed every 15 minutes during an hour for symptoms of RMS such as itching, erythema, chest pain and systolic blood pressure. Incidence of phlebitis was assessed by inspector twice a day from the insertion of peripheral catheter to the removal of the catheter. The data were analyzed by percentage, mean, $X^2$-test, t-test, repeated ANOVA, and logistic regression analysis using the SPSSWIN program. The results are summarized as follows; 1. No significant difference was identified in frequency of RMS between the experimental group and control group. 2. There was no significant difference in the change of systolic blood pressure as the time goes on between the experimental group and control group. 3. The incidence of phlebitis was significantly lower in the experimental group than in the control group. 4. The length of peripheral catheter placement was significantly longer in the experimental group than in the control group. 5. Other drugs administrated with vancomycin didn't influence the occurrence of phlebitis. However, the infusion method of vancomycin influenced the occurrence of phlebitis. The results suggest that 2 hour infusion of vancomycin(1g) in 200ml of isotonic saline every 12 hours may decrease the incidence of phlebitis and increase the length of peripheral catheter placement compared to 1 hour infusion of vancomycin(1g) in 100ml of isotonic saline every 12 hours. However, it does not reduce the incidence of RMS.

  • Background: We designed this randomized controlled trial (RCT) to assess whether lobaplatin-based concurrent chemotherapy might be superior to cisplatin-based concurrent chemotherapy for FIGO stage II and III cervical cancer in terms of efficacy and safety. Materials and Methods: This prospective, open-label RCT aims to enroll 180 patients with FIGO stage II and III cervical cancer, randomly allocated to one of the three treatment groups (cisplatin $15mg/m^2$, cisplatin $20mg/m^2$ and lobaplatin $35mg/m^2$), with 60 patients in each group. All patients will receive external beam irradiation (EBRT) and high-dose-rate intracavitary brachytherapy (HDR-ICBT). Patients in cisplatin $15mg/m^2$ and $20mg/m^2$ groups will be administered four cycles of $15mg/m^2$ or $20mg/m^2$ cisplatin intravenously once weekly from the second week to the fifth week during EBRT, while patients inthe lobaplatin $35mg/m^2$ group will be administered two cycles of $35mg/m^2$ lobaplatin intravenously in the second and fifth week respectively during pelvic EBRT. All participants will be followed up for at least 12 months. Complete remission rate and progression-free survival (PFS) will be the primary endpoints. Overall survival (OS), incidence of adverse events (AEs), and quality of life will be the secondary endpoints. Results: Between March 2013 and March 2014, a total of 61 patients with FIGO stage II and III cervical cancer were randomly assigned to cisplatin $15mg/m^2$ group (n=21), cisplatin $20mg/m^2$ group (n=21) and lobaplatin $35mg/m^2$ group (n=19). We conducted a preliminary analysis of the results. Similar rates of complete remission and grades 3-4 gastrointestinal reactions were observed for the three treatment groups (P=0.801 and 0.793, respectively). Grade 3-4 hematologic toxicity was more frequent in the lobaplatin group than the cisplatin group. Conclusions: This proposed study will be the first RCT to evaluate whether lobaplatin-based chemoraiotherapy will have beneficial effects, compared with cisplatin-based chemoradiotherapy, on complete remission rate, PFS, OS, AEs and quality of life for FIGO stage II and III cervical cancer.

  • Background: The prevalence of metronidazole-resistant H. pylori is almost 50% in Thailand which severely limits the use of this drug for eradication therapy. The aims of this study were to evaluate the efficacy and safety profiles of 7-day bismuth-based quadruple therapy including metronidazole as an initial treatment for H. pylori infection in a high metronidazole resistance area. Materials and Methods: This study was performed at Thammasat University Hospital and King Chulalongkorn Memorial Hospital during January 2009 to October 2010. Patients with non-ulcer dyspepsia (NUD) with active H. pylori infection were assigned to receive seven days of quadruple therapy (pantoprazole 40 mg bid, bismuth subsalicylate 1,048 mg bid, amoxicillin 1 gm bid and metronidazole 400 mg tid). H. pylori infection was defined as positive H. pylori culture or two positive tests (rapid urease test and histology). Antibiotic susceptibility test for metronidazole by Epsilometer test (E-test) was performed in all positive cultures. At least four weeks after treatment, $^{13}C$ urea breath test ($^{13}C-UBT$) was performed to confirm H. pylori eradication. Results: A total of 114 patients were enrolled in this study, 50 males and 64 females with a mean age of 49.8 years. All 114 patients had a diagnosis of NUD. Overall eradication as confirmed by negative $^{13}C-UBT$ was achieved in 94 out of 114 patients (82.5%). 44 patients had positive cultures and success for E-test. In vitro metronidazole resistance was observed in 22/44 (50%) patients. Eradication rate in patients with metronidazole resistant strains was 16/22 (72.7%) and 20/22 (90.1%) with metronidazole sensitive strains (72.7% vs 90.1%, p-value=0.12; OR=3.75 [95%CI=0.6-31.5]). Minor adverse reactions included nausea, bitter taste, diarrhea and black stools but none of the patients dropped out from the study. Conclusions: Initial treatment with 7-day bismuth-based quadruple therapy including metronidazole, amoxycillin and pantoprazole is highly effective and well tolerated for metronidazole-sensitive H. pylori infections. However, the efficacy markedly decline with metronidazole resistance. Longer duration of this regimen might be required to improve the eradication rate and larger multi-center studies are needed to confirm this hypothesis.
