본 연구는 고구마 사일리지를 이용한 고품질 돈육 생산을 위하여 고구마 사일리지가 돼지에 대한 생산형질과 경제성에 미치는 영향을 조사하였다. 사양시험은 고구마 사일리지를 고구마 70, 맥강 20, 대두박 10의 비율(사일리지 1)과 고구마 70, 맥강 30의 비율(사일리지 2)로 500kg 용 사일로에 충진하여 21일간 발효시켜 제조하고, 급여시기를 각각 체중이 75kg 과 90kg부터 시작하여, 급여시간은 각각 32일과 25일로서 체중 110kg까지 사육하며, 동일한 교배조합(LYD)으로 생산된 육돈 암컷을 3반복, 반복당 18두씩 총 324두를 공시하였으며, 고구마 사일리지 급여량을 하루에 두당 0.4kg씩 공급한 결과는 다음과 같다. 1. 고구마 사일리지를 급여한 경우 개시 체중 75kg과 90kg 공히 종료시 체중, 증체량, 일당증체량 및 사료효율은 배합사료를 무제한 급여하는 대조구 보다 유의적으로 낮았고, 배합사료의 섭취량과 일당사료섭취량은 유의적으로 적게 섭취하였으나, 고구마 사일리지를 건물로 환산하여 합산한 총사료섭취량은 대조구와 고구마 급여구간에 비슷하게 나타났다. 2. 고구마 사일리지를 급여한 경우 배합사료의 섭취량은 줄어들어 배합사료비가 절감되나 고구마 사일리지를 섭취함으로서 총사료비는 비슷하다. kg 증체에 소요되는 사료비는 높게 나타났고, 배합사료급여를 기준한 생산 지수는 고구마 사일리지 급여구가 40∼50% 이상의 사료비가 추가로 소요되는 것으로 분석되었다. This study was carried out to investigate the effects of supplementing sweet potato silages on live performance and production cost in finishing gilts. Two sweet potato silages containing same ingredients with different ratios(silages 1 and 2; 70 and 70% sweet potato, 20 and 30% barley bran, 10 and 0% soybean meal, respectively) were fermented for 21 days in 500 kg-capacity silos. Finishing gilts were fed a commercial finishing diet(CONT), or the same basal diet plus 0.4kg silage 1(TRT 1) or silage 2(TRT 2)/head/day beginning from either 75kg or 90kg of body weight up to approximately 110kg of final weight and the whole experiment was repeated 3 times. 1. TRT 1 and TRT 2 were lesser than CONT in final weight, total weight gain, average daily gain, feed efficiency and total and daily basal diet intake, but not in total dry matter intake including the silage. 2. Compared with CONT, TRT 1 and TRT 2 showed a reduced basal diet cost resulting from the reduced intake of it, but total feed cost was not different between the feeding regimens. Total feed cost per kg weight gain, however, was increased 40∼50% by supplementing the silage.

Cerebral angiography has been essential for the diagnosis of the intracranial aneurysms but. is sometimes accompanied by serious complications. Resolution of CT angiography was up-graded greatly to represent the three-demensional structure of vesseles since helical CT had been introduced. We have compared 26 cases of CT angiography and 28 cases of conventional angiography in terms of specificity and sensitivity for the diagnosis detectable aneurysm diameter. configurational diagnosis and diagnostic confidency. All results showed no statistical difference between CT angiography and conventional angiography. These should suggest that CT angiography could be replaced with conventional angiography for the diagnosis of ruptured aneurysms and even of unruptured aneurysms. resulting in the introduction of first screening modality of unruptured aneurysms.

가축의 생산성 증진을 위한 연구가 가축의 각종 환경분야로의 접근으로 지속되어 왔던바, 근래 가축의 복지향상을 통한 유전적인 잠재능력을 극대화하려는 노력들이 기울여지고 있다. 그러나 환경인자의 다양성과 작용기전의 복합성 및 측정방법의 비객관성으로 특정 환경인자의 독립적인 영향을 밝히기란 어려운 점이 많다. 가축의 복지와 생산성에 미치는 각종 환경요인의 영향에 대해서는 아직도 모호한 점이 많다. 그러나 궁극적으로 가축의 최적 생산환경 조성을 위한 모든 조치는 가축의 안락을 통한 생산활동의 지원에 있으므로 이 분야의 연구는 지속되어야 한다. 특히 인위적으로 가해지는 각종 환경요인의 영향이 규명되지 않고서는 관리기술의 진보를 기대하기는 어렵다고 할 것이다. 가축복지 분야의 최근 연구동향을 조사한 것으로 환경을 지배하는 시설요인이 가축의 생산성에 미치는 영향에 대해 여러 연구자들의 발표를 정리한 바 요약하면 다음과 같다. 1. 축군의 관리 측면에서 신체 일부분의 절단, 축군의 재배치와 혼합, 고립 혹은 격리 및 수송으로 인한 스트레스는 가축의 행동양식과 생산성에 크게 영향을 미치며, 각각의 효과는 축종에 따라 상반 될 수 있다. 2. 조기이유는 비정상정인 행동을 초래하며, 경우에 따라 장기적으로 영향하여 생산성을 저하시킬 수 있으며, 도살전 취급방법에 따라 육질에 영향을 미칠 수 있다. 3. 사육밀도 및 축군의 크기는 시설의 경제성과 관계가 매우 깊으며, 가축복지적 측면에서도 가장 중요한 요인이다. 4. 바닥면의 조건은 열환경을 지원하는 가장 중요한 인자일 뿐아니라 가축의 안락감에 가장 크게 영향하는 요인이다. 결론적으로 가축의 환경을 지배하는 모든 비기후적 인자가 생산성에 미치는 영향에 관한 연구는 활발하게 이루어지지 않았으나 앞으로 가축은 물론 관리자에게 안락감을 제공하여 최적 복지조건을 조성하고 생산성 향상을 도모해야 할 것이다. 특히 축사의 시설요인은 가축의 복지 및 행동습성과 밀접한 관계가 있으므로 시설요인에 의한 생산성을 저해하는 부정적인 영향을 제거하기 위하여 이 분야의 많은 연구가 요청된다. This review concentrated on recent studies published in the effect of housing conditions and manipulating husbandry systems on animal welfare and productivity. We should use the word "Welfare" in a scientific way so that may be useful when considering animal management or control of animal environment. When evaluating systems for housing conditions, manipulating factors and so on, we need precise measurements of how poor the welfare is. An accurate definition and measurement of both welfare and productivity is difficult. Since the measuring instruments are imprecise, any assessment of the correlation between welfare and productivity is often speculative. Notwithstanding these methodological problems a number of studies have indicated that some husbandry practices adversely affect both productivity and welfare. Further studies of animal welfare is required in relation to good welfare improving productivity.

Authors report a case of one-stage transoral decompression and posterior fusion in rheumatoid atlantoaxial subluxation. A 63-year-old man developed a rheumatiod atlantoaxial subluxation with mild weakness of all extremities which developed relatively suddenly 3 months after the initial symptom of neck pain. Skeletal traction followed by transoral decompression and occipitocervical fusion was performed on the same day. Postoperative course has been uneventful and revealed favorable fusion state of occipito-atlanto-axis. The pertinent literature on theumatoid atlanto-axial subluxation is reviewed and discussed.

This study was carried out to obtain the basic data on salted and fermented damsel fish(Jari-Jeot), one of the important traditional marine foods in Cheju-Do. and also to seek salt lowering method for the development of a new local tourist food. The results are as follows : The best organoleptic results were obtained after 60 days' fermentation for 25.0, 12.5 and 10% of salt-added group, and around 45 days for 7.5 and 5% of salt-added group. In raw fish ingredient IMP was abundant which marked 17.7 μmole/g while in fermented fish hypoxanthine was predominant but ATP and ADP were not detected after 30 days' fermentation. Sixteen kinds of free amino acids were detected and identified in Jari-Jeot instead of 17 kinds of those in raw sample. The abundant amino acids in Jari-Jeot after 60 days' fermentation were lysine. alanine, glutamic acid, glycine and leucine, and those were consisted of approximately 60% of the total free amino acids. During fermentation the content of TMAO was decreased gradually and no TMAO was detected after 75 days' fermentation while that of TMA was increased during fermentation up to 45 days' and decreased afterwards. The fatty acid of low-salt Jari-Jeot was composed of 31.9% of saturated acids, 13.2% of monoenoic acids and 54. 9% of of polyenoic acids. While the content of EPA in polyenoic acids was 1.9%, that of DHA was 23.0%. In order to lower salt concentaration of fermented damsel fish, additon of Pediococcus halophilus culture as a starter together with 10-12.596 of salt, 4-5% of KCI, and 2% of glucose gave as good quality as traditionally made Jari-Jeot.

Background : Serum osteocalcin is synthesized by osteoblast and has been shown to be sensitive indicator of bone turnover inpatients with various metabolic bone disease. In renal osteodystrophy, serum osteocalcin is elevated due to decreased renal clearance and elevated level of PTH. This study was done to evaluate the usefulness of serum osteocalcin as a marker of bone metabolism and the correlation with other biochemical markers of bone metabolism. Methods : We measured serum osteocalcin, calcium, phosphorus, ALP(alkaline phosphatase) and PTH(parathyroid hormone) in 37 patients with end stage renal disease on hemodialysis. Osteocalcin was determined by radioimmunoassay and PTH was determined by radioimmunometric assay. Results : 1) The mean level of serum osteocalcin in ESRD patients was 233.8± 218.2ng/ml which was significantly higher than that of controls(p<0.0001). 2) The mean level of serum PTH in ESRD patients was 40.5± 43.8pg/ml was significantly higher than that of controls(p<0.005). 3) There was a significant positive correlation between the level of serum PTH, ALP and the level of serum osteocalcin in ESRD patients. 4) By using multiple regression, PTH is most reliable factor that affect to elevated level of serum osteocalcin ( beta coefficient = 0.687, Sig T<0.05). Conclusion : Serum osteocalcin as a marker of bone metabolism in ESRD patients is more useful than other biochemical marker such as serum calcium, phosphorus, ALP and PTH is a most reliable factor that affect to elevated level of serum osteocalin.

송영환,김지영,채미경,박창식,김명철,전무형 충남대학교 형질전환복제돼지연구센터 2007 논문집 Vol. No.10

Shiga toxin-producing Escherichia coli (STEC) causes various clinical signs in human and animals, and has been indicated as a global enteropathogen with zoonotic importance. In this study, the feces of healthy pigs were collected from the slaughtered pigs of Daejon abattoir during the period from December 2001 to October 2002. Of 326 specimens, 13 STEC were confirmed by culture, PCR and colony hybridization. The isolates were further studied for toxin types, pathogenic factors, plasmid profiles, and antimicrobial resistance to characterize the genetic and toxigenic properties. In PCR, all of 13 isolates were evident to have shiga toxin gene (stx). Of 13 isolates stx1 gene was detected in 4 and stx2 gene in 9. The genes of eaeA, hlyA and rfbE were not present in any isolates. In colony hybridization using shiga toxin common primer (STXc), 2 to 9 per 100 colonies subcultured from 13 isolates showed the positive reaction. In the examination for plasmid profiles of the isolates, one to eleven plasmids with varying sizes of 1.0 Kb to 100 Kb were detected, and the 13 STEC could be classified into four groups by the plasmid patterns. The antimicrobial resistance patterns of the isolates were comparably corresponded with the plasmid profile patterns.
