The effect of post milking teat dipping on somatic cell count (SCC) of milk was determined in 20 Crossbred cows and 20 Murrah buffaloes selected from institute's herd. The animals were divided into two groups of 10 each. Animals of Group I (control) were teat washed with water before the milking while Group II animals were applied teat dipping solution after the completion of milking. The cows were milked 3 times a day while buffaloes were milked twice a day. The milk samples were collected from control and treated animals on day 0, 5, 10, 15, respectively. The milk samples were analyzed for milk constituents like fat, protein, lactose, chloride, IgG, NEFA, pH and EC and total and differential somatic cell counts. The changes in milk composition and somatic cell counts were significantly different (p<0.01) between the animals and between the breeds. However SCC, chloride content (p<0.05) and epithelial cells (p<0.01) varied during different days of study. The alterations in SCC, epithelial cells, TLC, lymphocyte, neutrophil, IgG, and protein content were significantly different (p<0.01) between control and treated groups. The pH, EC, protein, SCC, epithelial cells, lymphocyte and neutrophil cells of milk declined significantly (p<0.05) after the application of teat dipping, the respective values were 6.5 vs 6.40, 2.28 vs 2.37 mhos, 3.33 vs 4.04%, 1.00 vs $0.87{\times}10^5cells/ml$, 0.39 vs 0$0.34{\times}10^5cells/ml$, 0.36 vs $0.31{\times}1,000cells/ml$ and 0.17 vs $0.14{\times}1,000cells/ml$ in cows. However in buffaloes, epithelial cells, lymphocytes, neutrophils, EC and SCC declined (p<0.05) after application of teat dipping, the values being 0.37 vs $0.29{\times}10^5cells/ml$, 0.37 vs $0.25{\times}1,000cells/ml$, 0.14 vs $0.11{\times}1,000cells/ml$, 2.56 vs 2.37 mhos and 0.94 vs $0.73{\times}10^5cells/ml$, respectively. The study indicated that post milking teat dipping could be used as an effective method for the lowering of SCC in milk of crossbred cows and buffaloes.

Polymorphisms in the endothelial nitric oxide synthase (eNOS) gene may influence the risk of cancer, but the results are still debatable. Therefore, we performed a systematic review to provide a more complete picture and conducted a meta-analysis to derive a precise estimation. We searched PubMed, EMBASE, EBSCO, Google Scholar and China National Knowledge Infrastructure (CNKI) databases until April 2014 to identify eligible studies. Thirty-one studies with cancer patients and controls were included in the meta-analysis. Overall, the polled analysis revealed that the T-786C polymorphism was significantly associated with increased cancer risk under multiple genetic models (C vs T: OR=1.135, 95%CI=1.048-1.228; CC vs TT: OR=1.278, 95%CI=1.045-1.562; TC vsTT: OR=1.136, 95%CI=1.023-1.261; CC+TC vs TT: OR=1.159, 95%CI=1.047-1.281; CC vs TC+TT: OR=1.204, 95%CI= 1.003-1.447). G894T was associated with significant risk for females (TT vs GG: OR=1.414, 95%CI=1.056-1.892; TT vs GT+GG: OR=1.356, 95%CI=1.108-1.661) and for breast cancer (T vs G: OR=1.097, 95%CI=1.001-1.203; TT vs GG: OR=1.346, 95%CI=1.012-1.789; TT vs GT+GG: OR=1.269, 95%CI=1.028-1.566). Increased susceptibility was revealed for prostate cancer with 4a/b (ba vs bb: OR=1.338, 95%CI=1.013-1.768; aa+ba vs bb: OR=1.474, 95%CI=1.002-2.170). This meta-analysis indicated that the eNOS T-786C polymorphism is associated with elevated cancer risk; the G894T polymorphism contributes to susceptibility to breast cancer and cancer generally in females; and the 4a/b polymorphism may be associated with prostate cancer risk.

Background: The overall incidence of breast cancer in South Asian countries, including Nepal, is low compared to Western countries. However, the incidence of breast cancer among young women is relatively high. Breast cancer in such cases is characterized by a relatively unfavorable prognosis and unusual pathological features. The aim of this study was to investigate clinico-pathological and biological characteristics in younger breast cancer patients (<40 years) and compare these with their older counterparts. Materials and Methods: Nine hundred and forty four consecutive female breast cancer patients, admitted to the Department of Surgery, Tribhuvan University Teaching Hospital, Kathmandu, Nepal between November 1997 and October 2012, were retrospectively analyzed. Results: Out of the 944 female breast cancer patients, 263 (27.9%) were <40 years. The mean age was $34.6{\pm}5.0$ years among younger patients compared to $54.1{\pm}9.9$ for those ${\geq}40$ years. The mean age at menarche was also significantly lower ($13.5{\pm}1.5$ vs $14.2{\pm}1.5$ years p=0.001) while the mean duration of symptoms was significantly longer (7.6 vs 6.5 months p=0.004). Family history of breast cancer was evident in 3.0% of the young women versus 0.3% in the older one. Mammography was performed less frequently in younger patients (59.7%), compared to older (74.4%), and was of diagnostic benefit in only 20% of younger patients compared to 85% of older ones. At diagnosis, the mean tumor diameter was significantly larger in young women ($5.0{\pm}2.5$ vs $4.5{\pm}2.4cm$, p=0.005). Axillary lymph nodes were positive in 73% of younger patients and 59% of older patients. In the younger group, the proportion of stage III or IV disease was higher (55.1% vs 47.1%, $p{\leq}0.05$). The proportion of breast conserving surgery was higher in young patients (25.1% vs 8.7%) and a higher proportion of younger patients receive neoadjuvant chemotherapy (9.9% vs 2.8%). The most common histological type was ductal carcinoma (93.1% vs 86%). The proportion of histological grade II or III was higher in younger patients (55.9% vs 24.5%). Similarly, in the younger group, lymphatic and vascular invasion was more common (63.2% vs 34.3% and 39.8% vs 25.4%, respectively). Patients in the younger age group exhibited lower estrogen and/or progesterone receptor positivity (34.7% vs 49.8%). Although statistically not significant, the proportion of triple negative tumors in younger age group was higher (22.4% vs 13.6%). Conclusions: Breast cancer in young Nepalese women represents over one quarter of all female breast cancers, many being diagnosed at an advanced stage. Tumors in young women exhibit more aggressive biological features. Hence, breast cancer in young women is worth special attention for earlier detection.

The aim of this study is to determine whether full-mouth disinfection therapy(FMT) in our clinical setting would show better improvement of clinical parameters than partial mouth disinfection therapy(PMT) in chronic periodontitis and aggressive periodontitis patients. Among 12 patients, 6 were treated FMT and other 6 were treated PMT. Clinical parameters were calculated 3 months and 6 months after initial therapy. 1. There were no statistically significant differences between FMT and PMT in the reduction rate of bleeding on probing after 3 months, 6 months 2. Initial probing depth was 4-6mm, the mean probing depth after 3 months was 2.2mm vs 2.5mm(FMT vs PMT), after 6 months was 2.4mm vs 2.8mm. This was significantly lower in the FMT groups. 3. Initial probing depth was ${\geqq}$ 7mm, the reduction rate of mean probing depth during first 3 months was 4.8mm vs 4.1mm(FMT vs PMT), and 3 to 6 months was 0.5mm vs 0.3mm. This was significantly larger in the FMT groups. 4. Initial probing depth was 4-6mm, the mean clinical attachment level after 3 months was 2.3mm vs 2.7mm(FMT vs PMT), after 6 months was 2.7mm vs 3.0mm. This was significantly lower in the FMT groups. 5. Initial probing depth was ${\geqq}$ 7mm, the reduction rate of mean probing depth during first 3 months was 4.0mm vs 3.0mm(FMT vs PMT), and 3 to 6 months was 0mm vs -0.1mm. This was significantly larger in the FMT groups. Although the results provided us with succeccful clinical improvement in aggressive periodontitis, further research is needed to prove its additional benefit in the treatment of chronic periodontitis

Purpose: The aim of this study was to evaluate the effect of overexpression of heat shock protein 70 (HSP70) on the expression of inducible nitric oxide synthase and on the concentration of nitric oxide and to determine the mechanism for the relationship between HSP70 and inducible nitric oxide synthase (iNOS) in sepsis. Methods: Experiments were performed on male Sprague-Dawley rats, and sepsis was induced by using cecal ligation and puncture (CLP). Glutamine (GLN) or saline was administered 1 h after initiation of sepsis. We acquired serum and lung tissues from the rats 12 h or 24 h after initiation of sepsis. We analyzed the concentration of nitric oxide, the expression of HSP70 in the lung, and the gene expression of iNOS in the lung. Results: In CLP+GLN, glutamine given after initiation of sepsis enhanced the expression of HSP70 in the lung at 12 h (CLP+GLN vs. CLP:: $47.19{\pm}10.04$ vs. $33.22{\pm}8.28$, p = 0.025) and 24 h (CLP+GLN vs. CLP: $47.06{\pm}10.60$ vs. $31.90{\pm}4.83$, p = 0.004). In CLP+GLN, glutamine attenuated the expression of iNOS mRNA in the lung at 12 h (CLP+GLN vs. CLP: $4167.17{\pm}951.59$ vs. $5513.73{\pm}1051.60$, p = 0.025) and 24 h (CLP+GLN vs. CLP: $9,437.65{\pm}2,521.07$ vs. $18,740.27{\pm}8,241.20$, p = 0.016) and reduced the concentration of nitric oxide in serum at 12 h (CLP+GLN vs. CLP: $0.86{\pm}0.48$ vs. $3.82{\pm}2.53{\mu}mol/L$, p = 0.016) and 24 h (CLP+GLN vs. CLP: $0.39{\pm}0.25$ vs. $1.85{\pm}1.70{\mu}mol/L$, p = 0.025). Conclusion: The overexpression of HSP70 induced by the administration of glutamine in sepsis attenuated the gene expression of iNOS and reduced the concentration of nitric oxide.

The purpose of this study is to systematically determine an optimal percentile cut-off in histogram analysis for calculating the mean parameters obtained from a non-Gaussian continuous-time random-walk (CTRW) diffusion model for differentiating individual glioma grades. This retrospective study included 90 patients with histopathologically proven gliomas (42 grade II, 19 grade III, and 29 grade IV). We performed diffusion-weighted imaging using 17 b-values (0-4000 s/mm²) at 3T, and analyzed the images with the CTRW model to produce an anomalous diffusion coefficient (D_m) along with temporal (𝛼) and spatial (𝛽) diffusion heterogeneity parameters. Given the tumor ROIs, we created a histogram of each parameter; computed the P-values (using a Student's t-test) for the statistical differences in the mean D_m, 𝛼, or 𝛽 for differentiating grade II vs. grade III gliomas and grade III vs. grade IV gliomas at different percentiles (1% to 100%); and selected the highest percentile with P < 0.05 as the optimal percentile. We used the mean parameter values calculated from the optimal percentile cut-offs to do a receiver operating characteristic (ROC) analysis based on individual parameters or their combinations. We compared the results with those obtained by averaging data over the entire region of interest (i.e., 100th percentile). We found the optimal percentiles for D_m, 𝛼, and 𝛽 to be 68%, 75%, and 100% for differentiating grade II vs. III and 58%, 19%, and 100% for differentiating grade III vs. IV gliomas, respectively. The optimal percentile cut-offs outperformed the entire-ROI-based analysis in sensitivity (0.761 vs. 0.690), specificity (0.578 vs. 0.526), accuracy (0.704 vs. 0.639), and AUC (0.671 vs. 0.599) for grade II vs. III differentiations and in sensitivity (0.789 vs. 0.578) and AUC (0.637 vs. 0.620) for grade III vs. IV differentiations, respectively. Percentile-based histogram analysis, coupled with the multi-parametric approach enabled by the CTRW diffusion model using high b-values, can improve glioma grading.

Background: To compare the quality of life (QoL), the convenience of chemotherapy and satisfaction between colon cancer patients treated with FOLFOX4 and XELOX. Methods: The study was conducted in 26 patients with stage III colon cancer. Patients were received FOLFOX4 (n=17) or XELOX (n=9). QoL, convenience, and satisfaction were assessed using the Quality of Life Questionnaire-C30 (QLQ-C30), Quality of Life Questionnaire-Chemotherapy Induced Peripheral neuropathy (QLQ-CIPN) and Functional Assessment of Chronic Illness Therapy Chemotherapy Convenience and Satisfaction Questionnaire (FACIT-CCSQ), respectively. Patients completed questionnaires at baseline, at cycle 4 (C4) and cycle 8 (C8) (FOLFOX4) or at cycle 3 (C3) and cycle 6 (C6) visits (XELOX) and at their final visit. Results: In the QLQ-C30, at the final visit, XELOX patients had better functional scores than FOLFOX4 patients (physical: 85.7 vs.60.4, p=0.03; role: 83.3 vs. 57.5, p=0.04) as well as better symptom scores (constipation: 9.5 vs. 40.4, p=0.01). In CIPN, at the C6/C8 visit, XELOX patients had lower motor scale scores than FOLFOX4 patients (3.8 vs. 21.6, p=0.02). Moreover, at the C6/C8 visit, XELOX was more convenient than FOLFOX4 in FACIT-CCSQ (79.7 vs. 55.5, p=0.04). Male patients were especially likely to consider XELOX to be more convenient (90.0 vs. 55.0, p=0.01) and satisfactory (55.4 vs. 26.2, p=0.03) and fewer concern (91.0 vs. 65.0, p=0.03) than FOLFOX4. XELOX patients spent fewer days on hospital visits at C3/C4, C6/C8 and final visit (2.8 vs. 4.2, p=0.01; 2.7 vs. 4.1, p=0.01; 3.0 vs. 4.5, p=0.01). Conclusion: XELOX may be a better adjuvant chemotherapy choice for patients with colon cancer than FOLFOX4 in terms of QoL, convenience, and satisfaction.

체외순환은 뇌 혈류의 변화를 유도하며 이러한 변화가 수술 후 직 간접적인 뇌 손상의 원인이 될 수도 있다. 최근 체외순환 중 뇌 혈류 변화는 동맥혈액의 이산화탄소 분압과 밀접한 관련이 있는 것으로 보고되고 있다. 본 연구는 체외순환을 이용한 심장수술시 뇌 대사에 대한 정상 탄산분압과 고 탄산분압의 임상적 영향을 비교 조사하기 위해 전향적으로 계획되었다. 대상 및 방법: 심장수술이 계획된 36명의 성인 환자들을 연구목적에 따라 무작위적으로 정상탄산분압군(Pa$CO_2$35~40 mmHg, n＝18) 혹은 고탄산분압군(Pa$CO_2$45~55 mmHg, n＝18)으로 나눈 뒤 중등도 저체온(비인두 온도 29~3$0^{\circ}C$)의 비박동성 체외순환을 실시하였다. 수술 중, 각 환자들의 중대뇌동맥 혈류속도(뇌혈류 속도), 뇌동정맥 산소함량 차, 뇌산소 추출률, 뇌산소 대사율, 뇌산소 운반율, 뇌산소운반/뇌산소대사 비율, 뇌정맥 산소 불포화도(내경 정맥구 혈액 산소 포화도$\leq$50%), 동맥혈액 및 내경정맥 혈액 가스분석 등을 평가하였고, 수술 후 신경학적 합병증(섬망증세) 발생 정도 역시 관찰하여 양 그룹간에 비교하였다. 결과 : 체외순환 동안 고탄산분압군이 정상탄산분압군에 비해 뇌혈류 속도(169.13 $\pm$ 8.32 vs 153.11 $\pm$8.98%), 뇌산소 운반율(1,911.17$\pm$250.14 vs 1,757.40$\pm$249.56), 뇌산소운반/뇌산소대사 비율(287.38$\pm$28.051 vs 246.77$\pm$25.84), 내경 정맥구 산소분압(41.66$\pm$9.19 vs 31.50$\pm$6.09 mmHg), 그리고 내경 정맥구 산소포화도(68.97$\pm$10.96 vs 58.12$\pm$12.11%) 등이 유의하게 더 높았으나 (p＝0.03), 뇌동정맥 산소함량차(3.9$\pm$0.3 vs 4.9$\pm$0.3 mL/dL), 뇌산소 추출률(0.3$\pm$0.03 vs 0.4$\pm$0.03), 뇌산소 대사율(5.8 $\pm$0.5 vs 6.8$\pm$0.6), 동맥혈 pH는 고탄산분압군이 더 낮았다(7.36$\pm$0.09 vs 7.46$\pm$0.07, p＝0.04). 체외순환 동안 뇌정맥혈 불포화를 보인 환자 수는 고탄산분압군이 정상탄산분압군 보다 유의하게 더 적었다(3명 vs 9명, p＝0.03). 수술 후 신경학적 합병증(섬망)의 지속시간 역시 고탄산분압군이 정상탄산분압군 보다 더팔았다(36시간 vs 60시간, p=0.009). 결론: 이상의 연구결과들은 심장수술 동안 고탄산분압 체외순환이 뇌대사 및 수술 후 신경학적 결과에 보다 유익한 효과를 제공해 줄 수 있음을 시사하고 있다.
