  • Purpose: Although each Waldeyer's ring sub-site is considered an independent prognostic factor, few studies have assessed the prognosis and treatment of tonsillar lymphoma. Treatment outcomes were analyzed in patients with primary tonsillar lymphoma who were treated with chemotherapy and radiotherapy (RT). Materials and Methods: Nineteen patients with diffuse large B-cell lymphoma were evaluated, with a median follow-up of 53 months. Age, sex, and histology, amongst other factors, were reviewed. Progression-free survival (PFS) and overall survival (OS) rates were analyzed. Results: Most patients had Ann Arbor stage I-II (94.7%), IPI score of 0 (89.5%), and complete remission after chemotherapy (89.5%). The 5-year PFS and OS rates were 74.6% and 80%, respectively. In univariate analysis, the rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) regimen resulted in a better PFS than the cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) regimen (88.9% vs. 50.0%; p = 0.053). RT dose was related to the survival outcome (p = 0.010 for PFS, p = 0.044 for OS). Patients were classified into the CHOP + RT (>40 Gy) group and R-CHOP + RT (${\leq}40Gy$) group. The 5-year PFS rates were 50% in the CHOP + RT group, and 100 % in the R-CHOP + RT group (p = 0.018). The 5-year OS rates were 66.7% and 100%, respectively (p = 0.087). Conclusion: Primary tonsillar lymphoma patients typically have favorable outcomes. Chemotherapy (R-CHOP) combined with relatively lower dose consolidative RT may be safe and effective for primary tonsillar lymphoma.

  • Purpose: Sensory changes in the upper limb are complications of a mastectomy with immediate breast reconstruction with the treatment of breast cancer. The purpose of this study is to clarify whether immediate breast reconstruction worsens the sensory changes. Methods: From March 2004 to December 2005, 20 patients who had a mastectomy with immediate breast reconstruction(reconstruction group) were compared with 23 patients who had a mastectomy alone(control group). All patients had stage I or II breast cancer. The sensory changes were assessed in a blind manner by one examiner that used light touch sensation, static two-point discrimination, pain, vibration, hot and cold temperature perception. The sensory changes were identified along the sensory dermatome for diagnosing the damaged nerves. The following factors and their relationship with the sensory changes were analyzed : age, complications, and the mastectomy method. Results: There was no statistical difference in the static two-point discrimination, pain, vibration, hot and cold temperature perception between the two groups. However, the ability to recognize light touch was significantly better(p=0.045) in the reconstruction group than in the control group. The main site of sensory change was the proximal and medial portion of the upper limb in both groups. At these sites, the mean value of Semmes-Weinstein monofilament was $1.01g/mm^2$(reconstruction group 0.82, control group 1.17) and 2-point discrimination was 51.74(converted to perfect score of 100; reconstruction group 42.50, control group 59.78). The total rate of early complications was found to be significantly lower(p=0.006) in the reconstruction group than in the control group. Conclusion: These findings suggest that an immediate breast reconstructive procedure following a mastectomy is as safe as or safer than a mastectomy alone with respect to postoperative sensory changes of the ipsilateral upper limb.

  • Background: Breast cancer is the most common malignant tumor in females worldwide. Many differences exist in clinico-pathological characteristics of breast cancer patients between China and Western countries. This study aimed to analyze clinico-pathological characteristics of breast cancer from central China. Methods: Clinico-pathological information on breast cancer from three hospitals in central China was collected and analyzed. Results: From 1994 to 2012, 2,525 patients with a median age 50 years were included in this study. The 45-49-year age group and invasive ductal carcinoma not otherwise specified accounted for the highest proportions (19.1%, 480/2,525 and 81.0%, 1,982/2,446). Stages 0-I, II and III accounted for 28.0% (682/2,441), 48.4% (1,180/2,441), and 23.7% (578/2,441), respectively. Distribution of N stage showed that N0 accounted for 53.2% (1,344/2,525), and proportion of N0 rose from 51.1% (157/307) in 30-39-year age group to 64.3% (110/171) in ${\geq}$ 70-year age group, with an average increase of 2.1% in each age group. Modified radical mastectomy, radical mastectomy, breast-conserving surgery and simple mastectomy were performed for 71.8% (1,812/2,525), 18.0% (454/2,525), 5.2% (131/2,525) and 2.6% (66/2,525), respectively. Proportions of breast-conserving surgery in age ${\leq}$ 44-year group (68/132, 51.5%) and simple mastectomy in age ${\geq}$ 60-year group (57/89, 64.0%) were higher than in the other age groups. Breast cancers positive for estrogen receptor accounted for 53.0% (1,107/ 2,112). The comparisons among this study and other reports showed higher proportion of younger patients, lower proportion of breast-conserving surgery and positive estrogen receptor patients in China than western countries. Conclusions: Clinico-pathological characteristics in this study demonstrated clear differences between the center of China than Western countries. Additional classification systems should be developed to guide grading of early breast cancer more accurately, especially for N0 patients. Invasive ductal carcinoma is a focus for intensive research.

  • The fungus Botrytis cinerea causes fruit rot of strawberry and the damages can result in harvest losses upto 50%. Proper timing of fungicide application is essential for successful control of Botrytis fruit rot, fenhexamid plus iminoctadine tris, cyprodinil plus fludioxonil, fludioxonil alone, and Bacillus subtilis QST713 were applied to individual buds, flowers, and green and red fruit of cultivar 'Seolhyang' ex vivo. Cyprodinil plus fludioxonil or fludioxonil alone was applied i) before and after a 5-hr period of low-temperature ($0^{\circ}C$) incubation ex vivo ii) in field trials. Strawberry flowers and red fruit were more susceptible to B. cinerea than the green fruits. Incidence of Botrytis rot with fenhexamid plus iminoctadine tris and cyprodinil plus fludioxonil was the lowest at flowering, whereas B. subtilis QST713 did not significantly among treatments. In 2010, incidence of Botrytis fruit rot was significantly reduced when fludioxonil was applied two times at 1 week intervals from 50% bloom in field trials. Cultivars Redpearl and Seolhyang were more susceptible to low-temperature than cvs. Maehyang and Akihime. Cyprodinil plus fludioxonil application was effective when applied before onset of the low-temperature treatment period. Fludioxonil showed the most effective when it was sprayed one and more than two times in before and post low-temperature condition, respectively. These results demonstrate that fungicide selection and timing can interact with stage of fruit development and low-temperature in determining effectiveness of suppression of Botrytis fruit rot.

  • In the last few years, methods for in vitro culture of early embryo stages from oocytes matured and fertilized in vitro using suitable cell culture systems have been established. But the factors affecting pregnancy rates following transfer of bovine embryos produced in vitro were not evaluated enough. So this study was performed to investigate the effects of quality and stage of embryos, parity and Corpus Luteum quality of recipients on pregnancy rates following non-surgical transfer of bovine embryos produced in vitro. Oocytes aspirated from small antral follicles of ovaries obtained at a local slaughter house were matured, fertilized with frozen-thawed semen and co-cultured for 6-7 days by utilizing co-culture system with bovine oviduct epithelial cell in vitro. After co-culture, embryos were transfered to recipients on day 7 (estrus=day 0). Recipients were monitored by ultrasonic scanning method or observation for estrus and rectal palpation after 50 days from transfer. The results of this study are follows. 1. Of the 70 recipients, 70%(49 of 70) had not showed estrus sign between day 0 and day 50, but 22.9%(16 of 70) was diagnosed not pregnant. Therefore the overall pregnancy rate of this study was 47.1%(33 of 70). 2. The pregnancy rate of recipients transfered with excellent(66.7%) and good(54.5%) embryos were higher than that of recipients transfered with fair embryos(15.8%) (p<0.05). 3. The pregnancy rate of recipients transfered with morula, compacted morula, blastocyst and expanded blastocysts were 46.2, 55.0, 62.5 and 50.0%, respectively. 4. The pregnancy rates of recipients transfered to heifer and cow were 54.5 and 55.2%, respectively. 5. The pregnancy rates of recipients with CL score I, II(66.7, 63.6%) were higher than those of recipients with CL score III (10%), (p<0.05). Success of transfer of embryos produced in vitro depends on many variables. The important factors identified in this study were the quality of embryos and the CL score of recipient animals after non-surgical transfer of embryos matured, fertilized and cultured in vitro.

  • Community creates, receives and preserves the records, which made the community members and the entire society remember their history. As for community archives, archival appraisal is very political activity because appraisal of community records means whose memory remain alive in history. This study aims to analyze archival appraisal theories from the perspective of community and community archives, and suggest appraisal model for community archives. This study begins with examining the meaning of community archives and appraisal related issues including; i) community identity and independence of archives, ii) struggle of memory and multiple narratives, iii) uniqueness of each community and its archives, and iv) community archives as memory process and social inclusion. At the next stage, it deals with the archival theories from Schellenberg's archival values theory to macro-appraisal, to investigate possible application of theories for community records appraisal. It finds that the societal approach of macro-appraisal have advantage to appraise the community records. This study finally suggests the appraisal model for community archives by modifying the macro-appraisal components as well as by complying the principles of community archives. The model consists of the purpose and object of appraisal, principle and basis of valuation, and cooperation model between mainstream repository and community.

  • The purpose of this study was to examine the relationship among perceived health status, self-esteem, self-efficacy and health promoting behavior, and to determine the predictors of health promoting behavior in post-mastectomy patients. The study, a descriptive correlational study, was done with structural questionnaires. A total of 51 post-mastectomy subjects from C university hospital in Kwang-ju, South Korea completed mail-in self-reporting questionnaires during a three month period from March to June, 1999. The data were collected using Lawstone's(1982) perceived health status scale, Rosenberg's(1965) self-esteem scale, the modified self-efficacy scale(Shere et al, 1982), and the modified health promoting lifestyle profile (Walker et al, 1987). The data obtained were analyzed according to percentage, mean and standard deviation, principal component analysis, varimax rotation, t-test, ANOVA, Pearson's correlation, and stepwise multiple regression. The results were as follows: 1. The health promoting behavior measurement resulted in six factors. Each factor was labelled as follows: self-actualization, nutrition, stress management, exercise, health responsibility and interpersonal support. The total percent of variance explained by the six factors was 58.4%. 2. The mean score of health promoting behavior was 85.92(range 58~117). The scores of six factor were nutrition 3.20, self-actualization 2.59, stress management 2.58, interpersonal support 2.58, health responsibility 2.49, and exercise 2.34 on a four point scale. 3. When the score of health promoting behavior factors were compared by general characteristics. Factor I: self-actualization, differed significantly by the frequency of pregnancy (F=3.06, p=.037). Factor II: nutrition differed significantly by drinking experience(t=-2.26, p=.028) and the pre- or post stage of menopause(F=2.69, p=078). FactorIII: stress management differed significantly depending on regularity of mensturation(t=-2.12, p= .042). FactorIV: exercise differed significantly by type of religion (F=2.49, p=.072), marital status(F=5.03, p=.010), and feeding type (F=2.64, p=.036). Factor V: health responsibility differed significantly by regularity of mensturation(t=2.18, p=.037). 4. The total health promoting behavior score was significantly related to self-esteem and perceived health status(r=.610, p.006; r= .378, p=.006). The score of selfactualization also corresponded with selfesteem and perceived health status(r=.556, p=.001; r=.343, p=.013). 5. The predictor to explain the score of health promoting behavior was self-esteem, which accounted for 37.1% of the total variance. The predictor to explain the score of self-actualization was self-esteem, which accounted for 30.9% of the total variance. The score of nutrition was primarily affected by both premenopause and drinking experience, which accounted for 13.1% and 9.5% respectively. Finally, the score of exercise was dictated by marriage, Buddhism, no experience of breast feeding, which accounted for 17%, 9.8%, & 5.2% respectively. In conclusion, self-esteem is the main predictor for health promoting behavior in post-mastectomy women. These findings suggest a need for nursing strategies which promote self-esteem in such patients.

  • Background: Carcinogenesis is a multifaceted intricate cellular mechanism of transformation of the normal functions of a cell into neoplastic alterations. Metastasis may result in failure of conventional treatment and death Hence, research on metastatic suppressors in cancer is a high priority. The metastatic suppressor gene CD82, also known as KAI1, is a member of the transmembrane 4 superfamily which was first identified in carcinoma of prostate. Little work has been done on this gene in breast cancer. Herein, we aimed to determine the gene and protein level expression of CD82/KAI1 in breast cancer and its role as a prognosticator. Materials and Methods: In this study, 83 histologically proven cases of breast cancer and a similar number of controls were included. Patient age ranged from 18-70 years. Quantitative Real Time Polymerase Chain Reaction (q-RT PCR) and immunohistochemistry (IHC) were used to investigate KAI1 expression at gene and protein levels, respectively. Statistical analysis was done to correlate expression of KAI1 and clinicopathological parameters. Results: It was revealed that: (i) KAI1 was remarkably diminished in metastatic vs non metastatic breast cancer both at the gene and the protein levels (P < .05); (ii) KAI1 expression levels were strongly correlated with TNM staging, histological grade and advanced stage (p<0.001) and no association was found with any other studied parameter; (iii) Lastly, a significant correlation was observed between expression of KAI1 and overall median survival of BC patients (P = 0.04). Conclusions: Our results suggest that lack of expression of the KAI1 might indicate a more aggressive form of breast cancer. Loss of KAI1 may be considered a significant prognostic marker in predicting metastatic manifestation. When evaluated along with the clinical and pathological factors, KAI1 expression may be beneficial to tailor aggressive therapeutic strategies for such patients.

  • Through the previous studies(I,II), it was observed that human follicular fluid(HFF) was more effective than human fetal cord serum(HFCS) on promoting meiotic resumption of oocytes and improving embryonic development of mouse in vitro. On the basis of these results, we have gradually exchanged HFCS with HFF as protein supplement in human ART. This study was performed to investigate the efficiency of HFF on improving the pregnancy rate in ART. Oocytes were retrieved transvaginally from patients treated with pituitary suppression with GnRH-agonist and ovarian stimulation with human menopausal gonadotro-pin(HMG) and pure follicle stimulating hormone(FSH). Aspirated oocytes were rinsed and cultured in TCM-199 containing HFF, and the concentrations of HFF were adjusted to 10, 20, and 30% according to the use for insemination, embryo growth and embryo transfer, respectively. As possible as, we tried to do embryo transfer into fallopian tube to mimic the coincidence of the cell stage with the place of sojourn in vivo, so we performed various ART programs(IVF & ET; in vitro fertilization, ZIFT; zygote intra fallopian-tube transfer, ZIFT & ET) according to the tubal conditions of patients. On the while, intra cytoplasmic sperm injection(ICSI) was used to assist IVF of the patients who had shown poor standard IVF results by immunological or severe male factor. Of the 255 cycles of ART programs using HFF as protein supplement, 118 cycles were turn out to be succeeded in pregnancy(46.2%, per cycle, p<0.05), while 21 pregnancies were achieved in the 69 cycles using HFCS(30.4%). The 255 cycles using HFF were subdivided into cycles with the type of ART programs, and each pregnancy rate of the ART programs were 44.7% (IVF & ET, 76/170 cycles), 53.4%(ZIFT, 31/58 cycles) and 40.7% (ZIFT & ET, 11/27 cycles), respectively. In the 61 ICSI cycles using HFF, 28 cycles succeed in pregnancy(45.9%), while 7 pregnancies were obtained in the 17 ICSI cycles using HFCS. Also the ongoing pregnancy rate in the group using HFF(78.8%, 93/118 cycles) was higher than that in the group using HFCS(61.9%). Therefore, we found that the use of HFF as protein supplement was more suitable and effective than the use of HFCS to improve the pregnancy rate in ART.
