  • In this study, we investigated the effects of adding oat and lactic acid bacteria on the quality and functionality of yogurt. Yogurt was fermented with various lactic acid bacteria,; Lactobacillus acidophilus (LA), Lactobacillus delbrueckii sub. bulgaricus (LB), and Streptococcus thermophilussei (ST) and quality properties, β-glucan content, antioxidant activity were estimated. The quality of control and oat added yogurt (OY) showed significant differences depending on the type of strain and combination. The addition of oats significantly accelerated the lactic acid bacteria production, decreased the pH, and increased the titratable acidity and count of the viable cells compared to the control. Acid production was highest in ST, with the complex strains containing ST and LALBST showing high quality characteristics. The viscosity of oat yogurt was higher than that of the control group, and LALBST was also significantly higher than that of the control group. The β-glucan content of OY was 0.14-0.2%, and the organic acid content and antioxidant activity were also significantly increased by the addition of oats. As a result, it is thought that the addition of oats and a combination of lactic acid bacteria can be used for improving the quality and functionality of yogurt.

  • Background: Palliative chemotherapy with cisplatin/5-fluorouracil (5FU) is the commonest regimen employed for metastatic and recurrent head and neck squamous cell carcinoma (SCCHN) and nasopharyngeal carcinoma (NPC). However, this regimen is cumbersome requiring 5 days of admission to hospital. Carboplatin/5FU may be an alternative regimen without compromising survival and response rates. This study aimed to compare the efficacy and toxicity of carboplatin/5FU regimen with the cisplatin/5FU regimen. Materials and Methods: This retrospective study looked at patients who had palliative chemotherapy with either cisplatin/5FU or carboplatin/5FU for metastatic and recurrent SCCHN and NPC. It included patients who were treated at UKMMC from $1^{st}$ January 2004 to $31^{st}$ December 2009 with either palliative IV cispaltin 75 $mg/m^2$ D1 only plus IV 5FU 750 $mg/m^2$ D1-5 infusion or IV Carboplatin AUC 5 D1 only plus IV 5FU 500 $mg/m^2$ D1-2 infusion plus IV 5FU 500 $mg/m^2$ D1-2 bolus. The specific objectives were to determine the efficacy of palliative chemotherapy in terms of overall response rate (ORR), median progression free survival (PFS) and median overall survival (OS) and to evaluate the toxicities of both regimens. Results: A total of 41 patients were eligible for this study. There were 17 in the cisplatin/5FU arm and 24 in the carboplatin/5FU arm. The ORR was 17.7 % for cisplatin/5FU arm and 37.5 % for carboplatin/5FU arm (p-value=0.304). The median PFS was 7 months for cisplatin/5FU and 9 months for carboplatin/5FU (p-value=1.015). The median OS was 10 months for cisplatin/5FU arm and 12 months for carboplatin/5FU arm (p-value=0.110). There were 6 treatment-related deaths (6/41=14.6%), four in the carboplatin/5FU arm (4/24=16.7%) and 2 in the cisplatin/5FU arm (2/17=11.8%). Grade 3 and 4 hematologic toxicity was also more common with carboplatin/5FU group, this difference being predominantly due to grade 3-4 granulocytopenia (41.6% vs. 0), grade 3-4 anemia (37.5% vs. 0) and grade 3-4 thrombocytopenia (16.6% vs. 0). Conclusions: Carboplatin/5FU is not inferior to cisplatin/5FU with regard to its efficacy. However, there was a high rate of treatment-related deaths with both regimens. A better alternative needs to be considered.

  • Objectives : The purpose of this study is to compare the effects of laser acupuncture to the 830 nm on the five transport points with the spleen meridian for treatment to intestinal disease in rat with dextran sulfate sodium(DSS)-induced colitis. Methods : Colitis was induced by DSS for 20 days. The laser therapy on the five transport points of spleen meridian (Laser Well Point-SP1(L-WE), Laser Brook Point-SP2(L-BR), Laser Stream Point-SP3(L-ST), Laser River Point-SP5(L-RI) and Laser Sea Point-SP9(L-SE) was practiced twice a week for 5 times. Colon length was measured using a measuring point. Histological evaluation of colitis was conducted by hematoxylin and eosin(H&E) staining. Reverse transcription polymerase chain reaction(RT-PCR) was determined using western blotting and quantitative reverse-transcriptase polymerase chain reaction, respectively. Results: Colon length increased significantly L-BR and L-ST points after 5 times of therapy. Damage to the colonic mucosa is an integral feature of the DSS model, so control colonic mucosa tissue was damaged in the areas of ulceration resulting in complete epithelial loss. However histological damage decreased on the epithelial lining at all points. Cyclooxygenase(COX)-2 concentrations decreased in all points groups and Interferon(IFN)-${\gamma}$ increased in L-WE, L-BR, L-RI and L-SE points but L-ST was decreased when compared with control. White blood cell(WBC) and neutrophils(NE) decreased after the fifth acupuncture on the all points. But hemoglobin(HGB) increased after the fifth acupuncture on the L-WE, L-BR, L-ST and L-RI points. Also Mean corpuscular hemoglobin(MCH) and Mean corpuscular hemoglobin concentration(MCHC) decreased after the fifth acupuncture on the all points. Conclusions: The present study indicated that five transport points of the spleen meridian can prevent the development of DSS-induced colitis in rat. Thereby suggesting that should be available for decreasing DSS-induced inflammation in a colonic mucosa of tissue.

  • GMI (Fibrel${(R)}$) is one of the dermal filling substances which have been successfully used for the treatment of depressed cutaneous scar and wrinkles. It's major components are; Gelatin powder, which provides a framework for the clot to form and remains stable under the scar, and ${\varepsilon}$-aminocaproic acid, which inhibits the production of fibrinolysin, and Plasma, which provides the necessary ingredients for collagen synthesis. GMI has advantages of low immunogenicity and increased longevity. It has been known to induce fibroblast activity and promote new collagen synthesis. We used 34 Sprague-Dawley rats which were bred under the same condition and duration. 18 of experimental animals were undergone cardiac puncture, and their blood were collected, centrifugated, and stored in freezer. Out of 16 animals, control group were injected with 2ml plasma into the subcutaneous tissue of Lt. scapular, while experimental group were implanted of 2 ml GMI into the Rt. same area. Experimental animals were sacrificed at the 3rd day, 5th day, 1st week and 2nd week respectively after implantation of GMI. To observe the histopathologic change of GMI and surrounding tissue reaction of GMI, we had examined with H&E staining, immunohistochemical staining with vimentin, ${\alpha}$-SMA, S-100 under LM and SEM. The obtained results were as follows ; 1. In LM study, the inflammatory cell infiltrations and granulation tissue formation were observed, and muscle tissues were well attached with adipose tissues in the control group. In the experimental group, inflammatory cell infiltrations had been observed by the 2nd week and irregular adipiose tissues and well differentiated mesenchymal tissues were examined. 2. In immunohistochemical study, the experimental group of ${\alpha}$-SMA study, there were a prominent positive response on endothelial development of granulation tissues and mesenchymal tissues compare with the control group. In vimentin study, positive response on mescenchymal fibroblast continued to 2nd week, but negative in the control group. In S-100 study, both groups were positively responded on irregular adipose tissues. 3. In SEM study, collagen fibers were embedded by the plasma by the 5th day in the control group, and in the 3rd day experiment GMI were resorved but communited with collagen fiber till the 1st week. Collagen fibers were infilt-rated into GMI at the 2nd week and the infilltrated GMI were conglomerated with the mature adipose cells and the collagen fibers. From the above results, GMI implantation in the subcutaneous tissue of Sprague-Dawley rat, the mild infiltration of inflammatory cells were showed till 2nd week and the granulation tissues were observed. GMI were nearly resorbed till 2nd week, but well attached with adipose tissue and collagen fibers. The endothelium and fibroblasts were actively proliferated. Adipose tissues and mesenchymal tissue cells were observed. As already expressed, GMI showed resorptive change in course of time without any early immune reaction, and seemed to induce fibroblast activity and promote new collagen synthesis.

  • Objective: This study aimed to evaluate the effect of an intentionally created socket on bone remodeling with orthodontic tooth movement in rabbits. Methods: Eighteen male rabbits weighing 3.8 - 4.25 kg were used. An 8-mm deep and 2-mm wide socket was drilled in the bone 1 mm mesial to the right mandibular first premolar. The left first premolar was extracted to serve as an extraction socket. A traction force of 100 cN was applied to the right first premolar and left second premolar. Sections were obtained at the middle third of the moving tooth for both the drilled and extraction sockets and evaluated with hematoxylin and eosin staining and immunohistochemical analyses. The amount of tooth movement and tartrate-resistant acid phosphatase (TRAP)-positive cell count were compared between the 2 groups using the Mann-Whitney U test. Results: At week 2, the distance of tooth movement was significantly higher in the intentional socket group (p < 0.05) than in the extraction socket group. The number of TRAP-positive cells decreased in week 2 but increased in week 3 (p < 0.05). However, there were no significant differences between the groups. Furthermore, results of transforming growth factor (TGF)-${\beta}$ staining revealed no significant differences. Conclusions: The intentional socket group showed greater distance of tooth movement than did the extraction socket group at week 2. Osteoclast counts and results of immunohistochemical analyses suggested elevated bone remodeling in both the groups. Thus, osteotomy may be an effective modality for enhancing tooth movement in orthodontic treatment.

  • Background: Vascular endothelial growth factor (VEGF) is a potent mediator of angiogenesis. VEGF production is regulated by HIF-$1{\alpha}$ and EGFR. This study examined the relationship between the clinicopathological factors and VEGF, HIF-$1{\alpha}$ and EGFR protein overexpression, and evaluated their prognostic value in patients with a surgically resected non-small cell lung cancer (NSCLC). Methods: Patients who underwent a surgical resection at Kangnam St. Mary's hospital were reviewed retrospectively. The core biopsy samples from 54 patients with NSCLC were assembled on a tissue microarray (TMA), and immunohistochemical staining for the VEGF, HIF-$1{\alpha}$ and EGFR proteins was performed. The overexpression of these proteins was evaluated in relation to age, gender, histology and staging by univariate analysis. The clinicopathological prognostic factors were analyzed. Results: Multivariate analysis performed by Cox regression (odds ratio 2.8, 95% CI 1.0~8.2, p=0.046) revealed HIF-$1{\alpha}$ overexpression to be an unfavorable factor. There was no correlation between the overexpression of these proteins and the clinicopathological factors. VEGF showed a positive relationship with EGFR, but there was no statistical significance [$p(x^2)=0.06$]. Conclusion: HIF-$1{\alpha}$ overexpression predicts shorter survival in patients with a surgically resected NSCLC. Therefore, HIF-$1{\alpha}$ may be a poor prognostic factor in NSCLC.

  • Aurora kinase is a family of serine/threonine kinases intimately associated with mitotic progression and the development of human cancers. Studies have shown that aurora kinases are important for the protein kinase C (PKC)-induced invasion of colon cancer cells. Recent studies have shown that aurora kinase A promotes distant metastasis by inducing epithelial-to-mesenchymal transition (EMT) in colon cancer cells. However, the role of aurora kinase A in colon cancer metastasis remains unclear. In this study, we investigated the effects of aurora kinase A on PKC-induced cell invasion, migration, and EMT in human SW480 colon cancer cells. Treatment with 12-O-tetradecanoylphorbol-13-acetate (TPA) changed the expression levels of EMT markers, increasing α-SMA, vimentin, and MMP-9 expression and decreasing E-cadherin expression, with changes in cell morphology. TPA treatment induced EMT in a PKC-dependent manner. Moreover, the inhibition of aurora kinase A by siRNAs and inhibitors (reversine and VX-680) suppressed TPA-induced cell invasion, migration, and EMT in SW480 human colon cells. Inhibition of aurora kinase A blocked TPA-induced vimentin and MMP-9 expression, and decreased E-cadherin expression. Furthermore, the knockdown of aurora kinase A decreased the transcriptional activity of NF-κB and AP-1 in PKC-stimulated SW480 cells. These findings indicate that aurora kinase A induces migration and invasion by inducing EMT in SW480 colon cancer cells. To the best of our knowledge, this is the first study that showed aurora kinase A is a key molecule in PKC-induced metastasis in colon cancer cells.

  • This is a retrospective analysis of 135 patients with invasive carcinoma of the uterine cervix treated with curative radiotherapy from March 1983 through October 1989 at the Department of Therapeutic Radiology, Kang-Nam 51. Mary's Hospital. Among them, 78 patients received radiotherapy alone and 42 patients treated with neoadjuvant chemotherapy followed by radiotherapy and 15 patients were lost to follow up. All patients had follow up from 2 to 106 months (median; 62 months). Age of the patients ranged from 32 to 79 years at presentation (median; 59 years). According to FIGO classification, there were 20 ($16.7{\%}$) in stage IB, 19 ($15.8{\%}$) in stage IIA,49 ($40.8{\%}$) in stage IIB, 5 ($4.2{\%}$) in stage IIIA, 13 ($10.8{\%}$,) in stage IIIB,14 ($11.7{\%}$) in stage IVA. The pathological classification showed 96 ($80.0{\%}$) squamous cell carcinomas, 5 ($4.2{\%}$) adenocarcinomas and 19 ($15.8{\%}$) proven by cytology. The overall 5-year survival rates was $50.8{\%}$, and the 5-year survival rates by stage IB, IIA, IIB, IIIA, IIIB, IVA was $47.7{\%},\;70.2{\%},\;64.1{\%},\;40.0{\%},\;23.1{\%},\;14.3{\%}$, respectively. The 5-year survival rates was noted $51.2{\%}$ of radiotherapy alone and $50.4{\%}$of neoadjuvant chemotherapy followed by radiotherapy. The overall failure rate was $18.3{\%}$(22/120) including $11.7{\%}$ (14/120) locoregional failure, $5.8{\%}$ (7/120) distant metastasis and $0.8{\%}$(1/120) locoregional failure with distant metastasis. Treatment failure rates by the stages were $15{\%}$ (3/20) in stage IB. $10.5{\%}$ (2/19) in stage IIA, $10.2{\%}$, (5/49) in stage IIB, $20{\%}$ (1/5) in stage IIIA, $61.5{\%}$(8/13) in stage IIB, and $28.6{\%}$ (4/14) in stage IVA. The overall complication rate was $34.2{\%}$(41/120) including wet desquamation $7.5{\%}$, (9/120), diarrhea $6.7{\%}(8/120), radiation proctitis $5.8{\%}$(7/120) in decreasing order. A multivariate analysis of factors influencing the survival showed patient age (p < 0.0291), FIGO stage (p<0.0001), Karnofsky performance status (p<0.0043), initial hemoglobin level (p<0.0001), and intracavitary radiation (p<0.0004), but, no significancy in histology (p<0.29) and treatment method (p < 0.87).
