Background: Very limited information exists on the ruminal degradation kinetics of nutrients in garlic stalk. The present study aimed to survey the annual yield of garlic stalk in Korea and determine its feed-nutritive value for ruminants. Methods: In Experiment 1, garlic stalk was incubated in situ in the rumen of two Hanwoo steers ($360{\pm}15kg$ body weight) and removed after 12, 24, or 48 h to determine the ruminal degradation kinetics of DM and NDF. Rice straw was also included for comparison. In Experiment 2, In Experiment 2, six male Corriedale sheep were randomized to two dietary treatments to determine the apparent digestibility of nutrients in garlic stalk. Diets included a control ration without garlic stalk (60% concentrate mix +40% ryegrass) or a treatment ration (70% control diet +30% garlic stalk). Results: The Korean national yield of garlic stalk (sun-dried basis) in 2016 was estimated to be 31,910 tons, with the southern coastal regions producing the highest quantity. Compared with rice straw, garlic stalk had lower NDF, higher ADF, and greater effective degradabilities of DM and NDF, resulting in a greater TDN value (56.3%), which was higher than that obtained for rice straw (43.7%). Conclusion: These results provide basic information on the ruminal DM and NDF degradation kinetics of garlic stalk, which would be helpful for the efficient utilization of this by-product in ruminant diets

Eighty-four Holstein cows were used to evaluate effects of feeding two diets that differed in dietary cation-anion difference (cationic; +28 or anionic; -138 mEq/kg DM) on prepartum and postpartum dry matter intake (DMI), body weight (BW), body condition score (BCS), serum Ca concentrations and on subsequent milk production and composition. Treatments were in a $2{\times}3{\times}2$ factorial arrangement that included prepartum diet, dry period length (30 d dry, 30 d dry+estradiol cypionate (ECP), and 60 d dry), and prepartum and postpartum bST ($POSILAC^{(R)}$ 10.2 mg/d). No interaction of prepartum diet with dry period length or bST supplementation was detected for any measure evaluated either prepartum or postpartum. No significant effects of prepartum diet on prepartum DMI, BW or BCS were observed. Mean DMI during the first 28 d postpartum were similar for cows fed the cationic or anionic diets prepartum (25.5 vs. 26.1 kg/d). During postpartum wk 1 to 14, no differences in mean BW or BCS were detected due to prepartum diet fed but decreases for both groups were observed during the first 6 wk postpartum. No differences due to prepartum diet were observed for mean milk or 3.5% FCM yields or for milk composition during the first 10 wk of lactation. Similarly, mean milk yield of cows during the first 21 wk did not differ significantly due to prepartum diet fed (38.5 vs. 38.6 kg/d). Overall, cows fed the prepartum cationic or anionic diets had similar mean postpartum serum concentrations of Ca (9.34 vs. 9.35 mg/dl). Subsequent milk production, milk composition and concentrations of Ca did not differ. Importantly, the two prepartum diets were equally satisfactory in minimizing incidence of milk fever and in supporting initiation of lactation, irrespective of dry period length and supplemental ECP and bST.

Together with radiotherapy, chemotherapy using cytotoxic agents is one of the most common therapies in cancer. Metabolic changes in cancer cells are drawing much attention recently, but the metabolic alterations by anticancer agents have not been much studied. Here, we investigated the effects of commonly used cytotoxic agents on lung normal cell MRC5 and lung cancer cell A549. We employed cis-plastin, doxorubicin, and 5-Fluorouracil and compared their effects on the viability and metabolism of the normal and cancer cell lines. We first established the concentration of the cytotoxic reagents that give differences in the viabilities of normal and cancer cell lines. In those conditions, the viability of A549 decreased significantly, whereas that of MRC5 remained unchanged. To study the metabolic alterations implicated in the viability differences, we obtained the metabolic profiles using $^1H$-NMR spectrometry. The $^1H$-NMR data showed that the metabolic changes of A549 cells are more remarkable than that of MRC5 cells and the effect of 5-FU on the A549 cells is the most distinct compared to other treatments. Heat map analysis showed that metabolic alterations under treatment of cytotoxic agents are totally different between normal and cancer cells. Multivariate analysis and weighted correlation network analysis (WGCNA) revealed a distinctive metabolite signature and hub metabolites. Two different analysis tools revealed that the changes of cell metabolism in response to cytotoxic agents were highly correlated with the Warburg effect and Reductive lipogenesis, two pathways having important effects on the cell survival. Taken together, our study addressed the correlation between the viability and metabolic profiles of MRC5 and A549 cells upon the treatment of cytotoxic anticancer agents.

Two experiments were carried out to investigate whether duckweed is useful as a dietary protein source for fine-wool Merino sheep and to evaluate its effects on wool yield and characteristics. In Experiment 1, the sheep were given one of three maintenance diets consisting of oaten chaff (520-700 g/d) supplemented with 16-32 g crude protein/d in the form of fresh (1 kg/d) or sun-dried (50-100 g/d) duckweed. Each ration was estimated to provide 5.4 MJ (1.3 Mcal)/d of metabolisable energy (ME). The sheep readily ingested the fresh or dried duckweed. None of the wool measures (yield, rate of fibre elongation, fibre diameter) differed (p>0.05) between dietary treatments. In Experiment 2, oaten-chaff-based diets (800 g/d) supplying 6.5-7.2 MJ (1.6-1.7 Mcal)/d of ME were supplemented with iso-nitrogenous amounts (4-5 g N) either of urea (8 g), cottonseed meal (60 g) or dried duckweed (100 g). In this experiment, the rate of wool fibre elongation, thought to be related to intestinal amino acid absorption, was lower (p<0.05) for sheep given the oaten chaff/urea diet than for those given either oaten chaff/cottonseed meal or oaten chaff/duckweed for which the rates did not differ (p>0.05). Fibre diameter, which ranged from 16.0-16.7 mm, did not differ (p>0.05) between diets, but tended to be lower on the oaten chaff/urea diet so that volume of wool produced was also significantly lower (p<0.05) on this diet than on the diets containing duckweed or cottonseed meal. Rumen ammonia concentrations at 4.5 and 7.5 h after feeding were higher (p<0.05) for sheep given the oaten chaff/urea diet than for those given the other two diets. A comparison of the rumen ammonia concentrations, wool growth rate and predicted flows of amino acids from the rumen of sheep supplemented with duckweed rather than cottonseed meal suggested that duckweed is a valuable source of 'escape protein' for ruminants.

Background: Various pain treatments have been administered to relieve patients suffering from postoperative pain. Among these, epidural or intravenous opiate administration is by far the most widly applied treatment in recent times. However it was our objective to device a more effective and safe means of postoperative analgesia. Methods: We studied 110 healthy pregnant women scheduled for delivery by elective cesarean section. EPI(epidural)-group is administered morphine 1.5 mg and 0.25% bupivacaine 8 ml as bolus dose, then, a mixture of morphine 6 mg and 0.125% bupivacaine 95 ml as continuous dose via epidural route. IV(intravenous)-group is administered nalbuphine 6~7 mg as bolus dose and nalbuphine 60~70 mg with 0.9% normal saline 90 ml as continuous dose via intravenous route, at the rate of 2 ml/hr for 2 days. We compared the analgesic efficacy and side effects of these two groups using VAS pain score and time duration of constant pain level. Results: VAS pain score was similar between the two groups, but pain duration was significantly shorter in EPI-group. Incidence of pruritus was significantly lower with the IV-group, of nausea and vomiting were similar for both groups, no respiratory depression for either groups. Conclusions: Although the EPI-group had better analgesic efficacy, the IV-group had lower incidence of side effects, and simplicity and safety methods of operation. Therefore, We propose further research and consideration of administering the kinds and doses of those medications prescribe to the IV group in conjunction with other drugs for safer and better efficacy of postoperative analgesia.

Objectives: Non-vascularized iliac crest bone graft (NVIBG) is a known treatment option in mandibular reconstruction following jaw resection, but no documented review of patients treated with NVIBG exists for northern Nigeria. The experience and technique from a Nigerian tertiary hospital may serve as baseline data for comparison and improvement of practice for other institutions. Materials and Methods: A retrospective review of medical records and patient case files from January 2012 to December 2013 was undertaken. All case files and other medical records of patients who had reconstruction with NVIBG for benign or malignant lesions with immediate or delayed reconstruction were selected for review. Results: Twenty patients had mandibular reconstruction with NVIBG during the study period. Two patients were excluded because of incomplete medical records. Eighteen patients' (male=14, female=4) records were reviewed. Their ages ranged from 13 to 62 years (mean $26.0{\pm}10.6years$). Indications for NVIBG included jaw tumors (n=16; 88.3%), jaw cyst (n=1; 5.6%) and gunshot injury (n=1; 5.6%). Jaw tumors seen were ameloblastoma (n=15; 83.3%) and osteosarcoma (n=1; 5.6%). Treatments done were mandibular resection with condylar resection (n=7; 38.9%), mandibular segmental resection (n=10; 55.6%) and subtotal mandibulectomy (n=1; 5.6%). Patients' postoperative reviews and radiographs revealed good facial profile and continued bone stability up to 1 year following NVIBG. Conclusion: NVIBGs provide an acceptable alternative to vascularized bone grafts, genetically engineered bone, and distraction osteogenesis for mandibular reconstruction in resource-limited centers.

PURPOSE. The purpose of this study was to analyze the effects of two different implant surface treatments on initial bone connection by comparing the Removal Torque Values (RTQs) at 7 and 10 days after chemically modified, sandblasted, large-grit and acid-etched (modSLA), and Laser-etched (LE) Ti implant placements. MATERIALS AND METHODS. Twenty modSLA and 20 LE implants were installed on the left and right tibias of 20 adult rabbits. RTQs were measured after 7 and 10 days in 10 rabbits each. Scanning electron microscope (SEM) photographs of the two implants were observed by using Quanta FEG 650 from the FEI company (Hillsboro, OR, USA). Analyses of surface elements and components were conducted using energy dispersive spectroscopy (EDS, Horiba, Kyoto, Japan). RESULTS. The mean RTQs were $12.29{\pm}0.830$ and $12.19{\pm}0.713$ Ncm after 7 days (P=.928) and $16.47{\pm}1.324$ and $16.17{\pm}1.165$ Ncm after 10 days (P=.867) for LE and modSLA, respectively, indicating no significant inter-group differences. Pore sizes in the LE were $40{\mu}m$ and consisted of numerous small pores, whereas pore sizes in the modSLA were $5{\mu}m$. In the EDS analysis, Ti, O, and C were the only three elements found in the LE surfaces. Na, Ca, Cl, and K were also observed in modSLA, in addition to Ti, O, and C. CONCLUSION. The implants showed no significant difference in biomechanical bond strength to bone in early-stage osseointegration. LE implant can be considered an excellent surface treatment method in addition to the modSLA implant and can be applied to the early loading of the prosthesis clinically.

최근 이상기후 등 기후변화에 적응하고 관상가치가 높은 상록활엽수의 활용을 높이기 위한 재배 및 관리 기술이 요구되고 있다. 종가시나무 (Quercus glauca Thunb.) 1-2묘를 공시수종으로 하여 10개월간 경남 진주시 금산면에 위치한 산림바이오소재연구소 월아 시험림에서 1m×22.5m 크기의 묘상을 만들어 부직포 멀칭 소재 60g/㎡, 80g/㎡ 두 종류와 멀칭 방식 겹치기, 구멍뚫기 두 방식 그리고 멀칭을 하지 않은 대조구 총 5개 처리구로 각각 92본씩 시험지를 조성하였다. 부직포 멀칭 소재 60g/㎡ 겹치기 방식은 대조구와 비교 시 묘고는 약 1.9배 근원경은 약 1.1배 더 높은 값을 보였으며, 처리 간의 통계적 유의성은 없었다. 건전한 묘목은 H/D ratio 7.0 이하, T/R ratio 3.0 이하, 부위별 물질 생산량 값이 높은 조건으로 분석 결과, 이를 만족하는 것으로 조사되었다. 멀칭 처리에 따른 묘목의 품질을 평가할 수 있는 LWR, SWR, RWR 값을 대조구와 비교해 보면, 잎과 줄기를 포함하는 지상부의 생장은 증진되었지만, 뿌리를 포함하는 지하부의 생장은 대조구 값이 높은 경향을 보였다. 이를 바탕으로 묘목의 종합적인 품질을 평가할 수 있는 SQI 값은 대조구와 멀칭 처리간의 유의적인 차이가 있는 것으로 나타나, 멀칭 처리에 따른 생육증진 효과가 있음을 확인하였다. 엽록소 함량 분석에서는 대조구와 유의적인 차이가 있는 것으로 나타났는데, 대조구의 잡초 발생이 환경스트레스로 작용하여 엽록소 함량의 저하를 야기한 것으로 판단된다. 부직포 멀칭 소재 80g/㎡ 겹치기 방식은 잡초 발생량이 대조구 대비 약 4배 더 적게 발생하며, 식재지 조성인력과 제초작업에 소요되는 총 작업인력은 3.3인/100㎡/1일이 소요되는 것으로 조사되었다. 멀칭처리는 묘목의 생장과 품질 그리고 제초에 유의적인 차이가 있는 것으로 나타나 생육증진 효과가 있으며, 대규모 식재지를 포함한 일반수목 생산지에서의 제초작업에 투입되는 인력수급의 경제적인 부담을 줄일 수 있는 대안으로 판단된다.
