Using the colorimetric [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide](MTT)assay, we evaluated the chemosensitivity of 8 anticancer drugs{vincristine(VCR), vinblastine(VBL), adriamycin(ADR), cisplatin(CPDD), etoposide(VP-16), cytosine arabinoside(ara-C), bleomycin(Bleo) and cyclophosphamide(CYC)} and the cytotoxicity-enhancing effects of (±)-ar-turmerone and the extracts of the crude drugs {Lithospermum erythrorhizon(LE) and Scutellaria baicalensis(SB)}on the above mentioned anticancer drugs against HL-60 and KG-1 cells among 8 anticancer drugs, VCR, VBL, ADR, and CPDD inhibited the growth of both cell lines by more than 50% while VP-16, ara-C, Bleo, and CYC were less effective. (±)-ar-Turmerone had significant inhibitory effects against both cell lines, showing the ID_50 values of 11.730 ㎍/㎖ and 0.292 ㎍/㎖ for HL-60 and KG-1 cells. respectively. But the extracts of LE and SB roots showed no significant cytotoxic effects. According to ID_50 values, the cytotoxicities of VCR, VBL and ADR against HL-60 were enhanced two, eight and three times by mixing (±)-ar-turmerone, five, seven and three times by adding the extract of LE root, and twenty, six and three times by mixing the extract of SB root, respectively. The cytotoxicities of the above mentioned drugs against KG-1 cell were enhanced two, seven and three times by mixing (±)-ar-turmerone, two, three and three times by conbining wilth the extract of LB root, and two, five and two times by adding the extract of SB root, respectively. The cytotoxicity-potentiating effects of (±)-ar-turmerone and the extracts of LE and SB roots against HL-60 cell were greater than KG-1 cell.

We had grown Cd_0.78Zn_0.22S polycrystal thin films on slide substrate using chemical vapour deposition(CVD) method. We measured X-ray diffraction patterns in order to study Cd_0.78Zn_0.22S polycrystal structure. We studied its band gap using transmission curves and photocurrent and also analyzed photoluminescence using configurational coordinate model. We measured Hall effect·on this sample by Van der Pauw method and studied on carrier density and mobility depending on temperature.

Objectives: To compare the efficacy of two types specific exercise intervention (deep and superficial abdominal muscle exercises) in the treatment of patients with chronic low back pain (CLBP). Design: A randomized, comparative, repeated-measures. Subjects: Twenty-four patients with CLBP (at least for 3 months), mean age±SD=51.58±16.21 (yrs). Methods: Twenty-four patients with this condition were assigned randomly to two treatment groups. Both first and second group underwent 3 weeks specific exercise treatment program. The first group specific trained for the deep abdominal muscles. The second group specific trained for the superficial abdominal muscles. Results: After intervention, the first group showed a statistically significant reduction in pain intensity and functional disability levels (p<.05). The second group showed no significant change in these parameters after intervention (p>.05). Conclusions: According to results, a "deep abdominal muscle exercises" treatment approach appears more effective than a "superficial abdominal muscle exercises" treatment in patients with CLBP.

各種 土壤 管理가 柑橘品質에 미치는 影響 : Influence of Artificial Mulch during Fruit Development Season 夏秋季의 土壤被覆 效果

韓允三,韓海龍,文斗吉 제주대학교 1974 논문집 Vol.6 No.-

With polyethylene film and straw, artificial mulch from early Aug. to harvest time was experimented in a Citrus orchard on volcanic soil growing nine years old Satsuma mandarin(Citrus unshiu Marcovitch) on trifoliate orange stock. No matter what material is used, mulch delayed loss of soil water. Low soil moisture level desirable for delicious fruit quality was not attained by preventing rain flow to soil with polyethylene film, except only when mulched on already dried soil. While polyethylene film mulch increased soil temperature by 3'C at 10cm depth, straw mulch lowered soil temp. in summer. Change in soil temp. showed no apparent effect on fruit maturity and quality. Dry soil condition accelerated fruit coloring a little, and increased Brix, but decreased fruit weight, and didn't increased Brix-acid ratio. It was concluded that polyethylene film mulch could hardly be practiced to improve Citrus fruit quality in Seogwipo area orchards on volcanic soil.

Identification of Homer1 as a Potential Prognostic Marker for Intrahepatic Cholangiocarcinoma

Wu, San-Yun,Yu, Ming-Xia,Li, Xiao-Gai,Xu, Shu-Fang,Shen, Ji,Sun, Zhen,Zhou, Xin,Chen, Xing-Zhen,Tu, Jian-Cheng Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.7

Background: The aim of the present study was to analyze whether Homer1 is a potential prognostic marker for intrahepatic cholangiocarcinoma (ICC). Materials and Methods: The expression of Homer1 in ICC tissue was detected with immunohistochemistry and levels of protein in ICC and paratumor tissues were evaluated by Western blotting. Survival analysis by the Kaplan-Meier method was performed to assess prognostic significance. Results: Homer1 expression was high in 67.4% (58/86) of ICC samples, and there was significant difference between ICC and adjacent noncancerous tissues (p<0.001); high expression was associated with poor histologic differentiation (p=0.019), TNM stage (p=0.014), lymph node metastasis (p=0.040), and lymphatic invasion (p=0.025). On Kaplan-Meier analysis, a comparison of survival curves of low versus high expressors of Homer1 revealed a highly significant difference in OS (p=0.001) and DFS (p=0.006), indicating that high expression of Homer1 was linked with a worse prognosis. Multivariate analyses showed that Homer1 expression was an independent risk factor predicting overall survival[Hazard ratio(HR), 7.52; 95% confidence interval (CI), 2.63-21.47; p=0.002] and disease-free survival (HR, 11.56; 95%CI, 5.17-25.96; p<0.001) in ICC. Conclusions: Homer1 promotes lymphatic invasion and associates with lymph node metastasis and poor prognosis of ICC. The current study shows that Homer1 may be an independent prognostic factor for ICC patients after curative resection, and it provides an important basis for screening/treating high-risk patients.
