The purpose of the present study is to investigate the lipid peroxidation, creatine kinase activity and cortisol hormone levels following the training intensity in elite judo players. Six elite Judo players participated in the experiments (3h repetition judo program), which include stretching, judo skill practice and cool down without recess. Blood sampling were taken at the judo gymnasium at the time of resting, 1h training, 2h training, 3h training, 2h recovery, and 24h recovery time and this were analyzed for CK, MDA and Cortisol levels. The results obtained were analyzed via repeated measures of ANOVA using SPSS package program (ver.10.0) and a value of p<.05 was considered statistically significant. The results from this study were as follows. In the CK levels, which reflect the contribution of creatine phosphate and muscle damage degree, there was a significant difference (p<.05) after judo training in every period. Recovery 24h showed the highest level. In the MDA levels, which reflect lipid peroxidation, there was a significant difference (p<.05) after judo training. Recovery 2h showed the lowest level. In the cortisol hormone levels, which reflect stress status, there was a significant difference (p<.05). In this study, we can conclude that For the trained athletes, MDA level was lower at the time of exercise compare to the other period, this is caused by the increased antioxidant defence mechanism.

Purpose: Patients experiencing chemotherapy-induced peripheral neuropathy (CIPN) apply various palliative care as well as drugs in their daily life to alleviate symptoms. There is a need to identify the influence of these efforts and patients' psychosocial status on the relief of CIPN symptoms. This short-term prospective study investigated how prescription drugs, non-pharmacological behaviors (exercise, massage, and heat therapy), and psychological states (social support, depression, and anxiety) affected CIPN symptoms. Methods: Participants scheduled to receive postoperative platinum or taxane-based chemotherapy were enrolled consecutively. CIPN was measured with the Neurotoxicity-12 subscale of the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity-12 instrument. Data were collected three times during the 4 or 5 cycles of chemotherapy. Results: At the end of the 2nd chemotherapy cycle, 93.1% of participants reported CIPN symptoms. Multiple regression analyses showed that a heat therapy (β= -.34, p< .001), massage (β= -.21, p= .012), and walking 5 times or more per week (β= -.26, p= .021) provided relieve for CIPN symptoms. Depression (β= .19, p= .027) significantly exacerbated CIPN symptoms. Conclusion: These results suggested that a comprehensive management program that includes walking, heat therapy, massage, and mood therapy should be encouraged. Moreover, patients should be educated at chemotherapy initiation to understand appropriate interventions that can relieve CIPN symptoms.

The effects of adenosine 5'-triphosphate (ATP) and ATP analogs, P/sub 2y/ purinoceptor agonists, on growth of normal mouse mammary epithelial cells (NMuMG) were examined. Cells were plated onto 24 well plates in DMEM supplemented with 10 % fetal calf serum. After serum starvation for 24 hours, ATP, P/sub 2y/ purinoceptor agonists (AdoPP[NH]P, ATP-α-S, ATP-γ-S, β, γ-me-ATP and 2me-S-ATP), P/sub 2u/ purinoceptor agonist (UTP) and P/sub 2y/ purinoceptor antagonists (Reactive Blue 2, more selective to P/sub 2y/ receptor than PPADS; PPADS) were added. DNA synthesis was estimated as incorporation of 3H-thymidine into DNA (1 hour pulse with 1 μ Ci/ml, 18～19 hours after treatment). ATP, Adopp[NH]P, ATP-α-S or ATP-γ-S, significantly increased DNA synthesis at 1, 10 and 100 μM concentrations with dose-dependency (P<0.05), and the maximum responses of ATP and ATP analogs were shown at 100 μM concentration (P<0.05). The potency order of DNA synthesis was ATP≥ATP- γ -S>Adopp [NH]P>ATP-α-S. β, γ -me-ATP, 2me-S-ATP and UTP did not increase DNA synthesis. In autoradiographic analysis of percentage of S-phase cells, similar results were observed to those of DNA synthesis. Addition of 1, 10 or 100 μM Reactive Blue 2 or PPADS significantly decreased ATP (100 μM)-induced DNA synthesis, however, PPADS was less effective than Reactive Blue 2. In Elvax 40P implant experiment, ATP directly stimulated mammary endbud growth in situ suggesting the physiological regulator of ATP in mammary growth. ATP 100 μM rapidly increased MAPK activity, reaching a maximum at 5 min and then gradually decreasing to the base level in 30 min. ATP analogs, Adopp[NH]P and ATP-γ-S also increased MAPK activity, however, β, γ-me-ATP and 2me-S-ATP did not. The inhibitor of the upstream MAPK kinase (MEK), PD 98059 (25 μM), effectively reduced ATP (100 μM) or EGF(10 ng/ml, as positive control)-induced MAPK activity and DNA synthesis (P<0.05). These results indicate that ATP-induced DNA synthesis was prevented from the direct inhibition of MAPK kinase pathway. Overall results support the hypothesis that the stimulatory effects of normal mouse mammary epithelial growth by addition of ATP or ATP analogs are mediated through mammary tissue specific P/sub 2y/ purinoceptor subtype, and MAPK activation is necessary for the ATP-induced cell growth.

Background The deep inferior epigastric artery perforator (DIEP) flap is the commonest flap used for breast reconstruction after mastectomy. It is performed as a unilateral (based on one [unipedicled] or two [bipedicled] vascular pedicles) or bilateral procedure following unilateral or bilateral mastectomies. No previous studies have comprehensively analyzed analgesia requirements and hospital stay of these three forms of surgical reconstruction. Methods A 7-year retrospective cohort study (2008-2015) of a single-surgeon's DIEP-patients was conducted. Patient-reported pain scores, patient-controlled morphine requirements and recovery times were compared using non-parametric statistics and multivariable regression. Results The study included 135 participants: unilateral unipedicled (n=84), unilateral bipedicled (n=24) and bilateral unipedicled (n=27). Univariate comparison of the three DIEP types showed a significant difference in 12-hour postoperative morphine requirements (P=0.020); bipedicled unilateral patients used significantly less morphine than unipedicled (unilateral) patients at 12 (P=0.005), 24 (P=0.020), and 48 (P=0.046) hours. Multivariable regression comparing these two groups revealed that both reconstruction type and smoking status were significant predictors for 12-hour postoperative morphine usage (P=0.038 and P=0.049, respectively), but only smoking, remained significant at 24 (P=0.010) and 48 (P=0.010) hours. Bilateral reconstruction patients' mean hospital stay was 2 days longer than either unilateral reconstruction (P<0.001). Conclusions Although all three forms of DIEP flap breast reconstruction had similar postoperative pain measures, a novel finding of our study was that bipedicled DIEP flap harvest might be associated with lower early postoperative morphine requirements. Bilateral and bipedicled procedures in appropriate patients might therefore be undertaken without significantly increased pain/morbidity compared to unilateral unipedicled reconstructions.

본 연구의 in vitro 실험결과를 살펴보면, 배양액의 pH와 암모니아 생성량은 전 배양 시간동안 처리구간 통계적 유의차가 없었다. Total VFA, acetate, propionate, butyrate 생성량은 12 h에서 HPM을 0.2%, 1% 첨가한 시험구에서 대조구와 비교하여 증가하는 경향이었으나, 2% 첨가구에서는 오히려 감소되었고, 48 h에서는 HPM 첨가한 세 처리구에서 대조구와 비교하여 모두 증가하는 경향을 보였다. 반면에, 다른 배양시간대에서는 처리구간 통계적 유의차는 발견되지 않았다. A/P ratio 경우에도 처리구간 유의차가 없었다. 총 gas 생성량은 배양시간 24 h과 48 h에 HPM 처리구에서 대조구와 비교하여 증가하였다 (P<0.05). 한편 사양실험은 열처리된 단백질 (대두박)과 광물질의 복합 제제 (HPM)가 젖소의 유생산량과 유성분에 끼치는 영향을 조사하기 위하여 수행되었는데 그 결과를 요약하면, 유생산량은 대조구와 비교하여 HPM 시험구에서 하루에 약 1kg 정도 더 높았고 (27. 7 vs 28.8 kg/d, P<0.001), 4% FCM 생성량 또한 대조구와 비교하여 볼 때 HPM 시험구에서 1.3 kg/d 이 더 높았다 (P<0.001). 유단백 (P<0.05)과 SNF (P<0.05)도 대조구와 비교하여 HPM 시험구에서 그 생산량이 증가되었다. 반면에, 유지방, MUN과 체세포수는 처리구간 통계적 유의차가 발견되지 않았다. 이상의 결과로 보아, HPM 첨가에 의한 반추위 발효 저해현상은 없었으며, HPM 내 함유되어 있는 열처리된 단백질과 광물질의 결합체와 잔여 광물질이 반추위 내 단백질과 결합하여 단백질 분해 속도를 지연시킴으로써, 단백질의 by-pass율을 증가시켜, 유생산량 증가와 유질을 개선 (유단백질, SNF 함량 증가 등) 하는 등 젖소의 생산성을 향상시킨 것으로 요약할 수 있다.

Background: Increasing evidence has indicated that high Forkhead box protein C2 (FOXC2) level is closely associated with the development, progression, and poor prognosis of a variety of tumors. However, the relationship between FOXC2 and the progression of human gliomas remains to be clarified. The aim of present study was to assess FOXC2 expression and to explore its contribution in human gliomas. Materials and Methods: Realtime quantitative PCR was performed to examine FOXC2 expression in 85 pairs of fresh frozen glioma tissues and corresponding non-neoplastic brain tissues. Associations of FOXC2 expression with clinicopathological factors and prognosis of glioma patients were statistically analyzed. Results: The relative mRNA expression of FOXC2 was significantly higher in glioma tissues than the corresponding non-neoplastic brain tissues (p<0.001). In addition, high FOXC2 expression was significantly associated with advanced pathological grade (P=0.005) and the low Karnofsky performance score (KPS) (p=0.003), correlating with poor survival (p<0.001). Furthermore, multivariate Cox regression analysis showed that high FOXC2 expression was an independent predictor of overall survival (p=0.006). Conclusions: FOXC2 may act as an oncogenic gene and represent a potential regulator of aggressive development and a candidate prognostic marker in human gliomas.

본 연구는 Terpenoid 함유 식물 추출물을 이용하여 in vitro 반추위 발효성상 및 메탄생성에 미치는 영향을 알아보고자 수행하였다. 반추위액은 티머시(timothy)와 농후사료를 6:4의 비율로 급여한 반추위 cannula가 시술된 한우 암소에서 채취하였다. 본 실험에 사용한 식물추출물은 박하(Mint), 소나무(Pine), 삼나무(Japan cedar), 초피나무(Sichuan pepper), 편백(Hinoki cypress) 그리고 해송(Japanese black pine)을 사용하였으며, 반추위액과 McDougall buffer를 1:2의 비율로 혼합한 배양액을 0.3g 티머시와 식물 추출물(기질의 5%)이 담긴 50ml serum bottle에 혐기상태로 15ml를 분주하였다. Serum bottle은 $39^{\circ}C$, 150rpm으로 3, 6, 9, 12, 24, 48 및 72시간 동안 배양하였다. 실험 결과 pH 값은 점점 감소하였으며, 전 배양시간에 걸쳐 대조구보다 유의적(p<0.05)으로 높았다. 건물 소화율은 배양 3시간대는 Mint 처리구만 유의적(p<0.05)으로 높았으나, 이후 24시간까지 모든 처리구에서 유의성이 없었다. 총 가스발생량은 전 처리구에서 유의적(p<0.05)으로 낮았으며, 이산화탄소 발생량은 배양 12시간대까지 감소하였으나, 그 이후는 유의적 차이가 없었다. 메탄 발생량의 경우 24시간대에 대조구에 비해 모든 첨가구에서 유의적(p<0.05)으로 감소하였다. 미생물 성장량은 첨가구에 따라 각각 다른 양상을 나타냈으나 24시간대는 모든 처리구에서 유의적(p<0.05)으로 성장량이 감소하였다. 암모니아 측정량은 배양 12시간부터 첨가구에서 증가하는 경향을 보였으나 72시간대는 감소하였다. acetic acid 및 propionic acid도 대조구보다 유의적(p<0.05)으로 높은 것을 확인할 수 있었다. 결과적으로 본 실험에 사용한 Terpenoid 함유 식물 추출물 6종 모두 소화율에 영향을 미치지 않으며 메탄저감 효과를 나타내었다. 특히 Mint 및 Pine 추출물은 총 VFA, acetic acid 및 propionic acid의 생성을 증가시켰으며 상기의 결과를 종합하였을 때, 반추위 발효성상에 악영향을 미치지 않으며 메탄 발생을 저감하는 식물 추출물로는 Mint 및 Pine이 적합하다고 생각된다.

본 실험은 TNT 오염토양의 효율적 제거를 위한 화학적 처리기술 개발을 목적으로 다양한 Fenton reaction 적용성에 관해 고찰하였다. 기존 Fenton reaction은 낮은 pH 요구성을 가지는 단점이 있고 천연토양은 pH에 대한 buffering capacity를 가지고 있으므로 그 적용성이 미약하였다. 이에 중성 pH에서도 효율적으로 Fenton reaction을 유도할 수 있는 modified Fenton reaction을 본 실험에 적용하였다. 또한, 천연 토양 내 다양한 철광석을 철이온 대신 사용함으로써 철슬러지의 발생의 최소화를 위한 Fenton-like reaction의 적용 가능성에 대하여 검토하여 보았다. 실험결과는 오염토양의 기존 Fenton reaction 제거효율은 약 20시간 후 pH 3에서 93%이며 반면 pH 7에서는 21%임을 보였다. 한편, TNT 오염 수용액 처리에 철이온과 5종의 chelating agent를 투입한 실험에서는 24시간 반응 후 pH 7에서 NTA-Fe의 경우가 87%로 그 효율이 가장 우수하였고 citrate-Fe 46%, EDTA-Fe 71%, oxalate-Fe 64%, acetate-Fe 37%의 각각의 제거효율을 나타내었다. 또한, TNT 오염 수용액 처리에 3종의 철광석으로 Fenton-like reaction을 적용한 경우, pH 3에서 24시간 후 goethite 33%, hematite 40%, magnetite 40%의 처리효율을 보였고, pH 7인 경우 goethite 28%, hematite 34%, magnetite에서는 36%의 처리효율을 보였다. 게다가, 성능이 우수한 chelating agent 3종과 2종의 철광석을 이용한 복합처리 실험에서는 magenetite 경우 pH 7에서 NTA 79%, oxalate 59%, EDTA 14%의 제거효율이 측정되었고, hematite 경우 NTA 73%, oxalate 25% 그리고 EDTA 19%의 처리효율을 얻었다. 결론적으로 철광석과 modified fenton reaction의 복합처리의 경우 처리 기간 등의 운영인자를 확보할 경우 효율적으로 TNT 오염토양에 적용될 수 있을 것으로 기대된다.
