  • 급속히 변화하는 현대사회에서 생활수준의 향상과 식생활의 서구화 및 신체의 활동량 감소, 과잉 영양공급으로 체중이 증가하여 체형의 변화가 일어난다. 이에 본 연구에서는 체형을 변화시키는 여러 요인 중에서 피하지방으로 인한 변화를 알아보기 위해 초음파 피하지망 계측기를 사용하여 20대 남성을 대상으로 19 .approx. 24세를 집단1, 25 .approx. 28세를 집단2로하여 각 집단간의 피하지방 분포경향과 각 집단간의 피하지방 계측피를 요인분석하여 남성복 의복제작 및 현대남성의 올바른 체형해석을 위한 기초자료 제공이 본 연구의 목적이다. 피하지방이 침착하기 쉬운 부위는 허리앞1/2과 배앞 1/2로 나타 났고, 피하지방이 침착하기 어려운 부위는 하퇴전면으로 나타났다. 피하지방두께 계측에서 집단간 유의 차 검증결과 20대 후반으로 연령이 증가함에 따라 작은 폭으로 지방침착이 일어났다. 집단1의 요인분석 결과 요인1은 허리부위, 요인2는 체간부1/2과 체간부 측면부위로 나타났다. 집단2의 요인분석결과 요인 1은 윗가슴부위와 허리부위, 요인2는 전체적부위로 나타났다. 전체집단에서는 요인분석결과 요인1은 상 지, 하지부위, 요인2는 허리부위로 나타났다. 연령의 증가와 함께 피하지방 침착이 체간부 하부인 허리 와 배를 중심으로 이루어지는 것으로 나타났다.

  • 오존과 같은 광화학 오염물질은 생성과정이 복잡하여 오존 Episode를 예측하는 것은 매우 어렵다. 이러한 복잡한 광화학 반응 메카니즘을 모사하기 위해서는 3-dimensional Eulerian Grid Model을 이용하는 방법이 있다. 본 연구에서는 산성침착모델인 RADM를 사용하였으며 이 모델은 산성침착과 관련된 건성침착, 습성침착 등 여러 가지 과정과 대기중에서 발생하는 광화학 반응을 포함하는 화학반응 모듈을 사용함으로써 오존과 같은 광화학 오염물질의 모사에도 사용될 수 있다(Chang, et al., 1987).(중략)

  • The study aimed to investigate in vitro lipid deposition of oleic acid, oleic acid methyl ester and cholesterol on a daily disposable (1-day lenses) and 3-days lenses over 3 days and changes of optical characteristics is also investigated. Artificial tear solutions were prepared to simulate actual tear compositions. Two types of contact lenses (1-day lenses (Senofilcon A) and 3-days lenses (silicone tripolymer)) were soaked in the artificial tear solutions within an incubator at 37 ℃ with 150 rpm for 8, 16, 24 hours. Lipid deposition (oleic acid, oleic acid methyl ester and cholesterol) were measured using high performance liquid chromatography (HPLC) instrument. In addition, measurements of oxygen transmissibility, light transmittance and observation of lens surface were conducted. The amount of lipid deposition on the 1-day lenses were 127.55 ㎍/lens for Day 1, 302.96 ㎍/lens, for Day 2, and 353.30 ㎍/lens for Day 3. The 3-days lenses were 46.22 ㎍/lens for Day 1, 66.07 ㎍/lens for Day 2, and 67.45 ㎍/lens for Day 3. Oxygen transmissibility were 81×10-9(cm/sec)(ml O2/ml×mmHg)(Baseline) and 48×10-9(cm/sec)(ml O2/ml×mmHg) (Day 3) for the 1-day lenses, it were 13.23×10-9(cm/sec)(ml O2/ml×mmHg)(Baseline) and 9.6×10-9(cm/sec)(ml O2/ml×mmHg) (Day 3) for the 3-days lenses. Transmittance of each lenses were 97.21% (Baseline) and 94.25% (Day 3) for the 1-day lenses, 97.65% (Baseline) and 95.15% (Day 3) for the 3-days lenses. Observation of surface deposition indicated greatest deposition for the 3-days lenses type on Day 3. Lipid deposition for both lens types increased by day and was greater for the 1-day lenses type. Surface deposition appeared to differ as it was greatest for the 3 days lens type, which may suggest other deposits such as protein may be present.

  • Fatty pancreas is an abnormal process of lipid deposition in cells, resulting in increased fat tissue and obesity. The result is a risk factor for cardiovascular and metabolic diseases. The aim of this study was to evaluate the usefulness of pancreatic fat as a predictor of cardiovascular disease and metabolic syndrome in pancreatic ultrasonography. In 407 patients who underwent a comprehensive screening at the W Health Care Center in Busan from September 2. 2018 to December 31, 2018, the degree of fat deposition in the pancreas was evaluated as the degree of mild, moderate. Data on non-obstructive atherosclerosis, BMI, hyperlipidemia, hypertension, and diabetes were collected to assess the association of pancreatic fat deposition with cardiovascular disease and metabolic syndrome. In addition, we tried to analyze the correlation between liver dysfunction and thyroid dysfunction as the degree of fat pancreas increased. We examined the relationship between six parameters including atherosclerosis, BMI, hyperlipidemia, hypertension, diabetes, liver dysfunction, and thyroid dysfunction among patients with fatty pancreas. We concluded that the carotid intima-media thickness of atherosclerosis, which is a risk factor of cardiovascular disease, is most closely related to fatty pancreas.

  • This study investigated the muscular dystrophin levels in freely moving Australian cattle mainly fed grass, freely moving Korean cattle fed mainly a grain diet, and Korean cattle fed a grain diet but housed in a relatively limited space of a cow house. The total skeletal muscle specimens of 244 cattle were collected and immediately fixed in 10% neutral formalin. The same area was biopsied from the cattle in both countries. The findings showed that fatty infiltration is highly correlated with membrane-associated protein degradation in skeletal muscle, and that among several membrane-associated proteins, dystrophin showed the most significant reduction in expression in the cattle with fatty infiltration. Similarly, CD36 was more highly expressed in the cattle with fatty infiltration of skeletal muscle. Various breeding factors, such as oxidative stress; the presence of oxidized lipids in the diet; and environmental factors such as exercise, temperature and amount of time spent, may have critical effects on the degradation of normal cytoskeleton proteins, which are required for maintaining normal skeletal muscle architecture. Among the sarcolemma membrane-associated proteins, dystrophin is the most sensitive membrane protein that is involved muscular dystrophy and muscular degeneration. Thus, the present findings may be useful for studies on muscular dystrophy in humans or the pathogenesis of muscular diseases in animal models.

  • 5월호에서는 농후사료 급여량이 비육능력에 미치는 영향 및 수익성에 대하여 기술하였다. 결국 소를 키우는데 있어서 그 소의 체질능력에 맞는 사료를 얼마만큼 적정량을 급여하느냐가 농장경영의 수익성에 중요하다는 것을 알수 있었을 것이다. 이어서 이번호에서는 출하월령이 비육능력에 미치는 영향 및 수익성에 대하여 기술하고자 한다. 소를 잘키우는 것도 중요하지만 소의 능력을 감안 어느 시기에 출하를 하여 수익을 내는가 하는것도 중요하다. 특히 거세우로 고급육을 지향하는 농가에서는 그 중요성은 말할나위없이 크다 할것이다. 조기에 출하하여 등심에 지방이 미처 참작되지 않아 육질과 육량등급에 나쁜 영향을 줄수도 있지만 너무 오래 키워서 지방이 많이 침착이 되어도 등급에서는 나쁜등급을 받을수가 있다는 것을 명심해야 할 것이다. 결국은 얼마나 적기에 출하 시기를 맞추느냐 하는 것이 농가 경영의 수익성과 밀접한 관계가 있는 것이다.

  • The effect of fiber sources on lipid metabolism was investigated in relation to the level of dietary fat. After rats were fed each diet for 4 weeks, all animals were sacrificed to collect the liver, and blood samples by heart puncture. Total lipid, total cholesterol, phospholipid and HDL- cholesterol were determined in serum. Total lipid and total cholesterol were also determined in liver. These results were compared with the histochemical appearances by the method of Oil red-O staining. Higher level of fat in the diet appeared to increase the total lipid levels in serum and more fat in the liver cells were shown from the high fat diet judging from the E.M. pictures. Phospholipid concentration in serum was greater in the rats of high fat groups than those of the control or non-fat groups. High fat level caused to decrease the HDL- cholesterol concentration in serum. Pectin decreased serum and liver lipids and the deposit of fat in the liver cells. HDL-cholesterol levels in serum was increased by pectin. Whereas the cellulose supplementation had no effect to reduce serum and liver total lipid levels, and cellulose did not decreased the deposit of fat in the liver cells. From these results, it is concluded that dietary fat levels led to changes in the lipid metabolism of rats and pectin may exhibit a lowering total lipid contents in serum and liver. Cellulose may slightly elevate serum and liver levels, or have no lowering effect.

  • Although lipoma is the most common soft-tissue tumor, accounting for up to one half of all soft-tissue tumors, intra-articular synovial lipomas are rarely seen. Occasional cases of intra-articular lipoma arborescens have been reported. However, true intra-articular synovial lipomas should be differentiated from other similar lipomatoid conditions such as lipoma arborescens, which are different pathologic entities and show different clinical presentations. This article presents the case of a patient who had an intra-articular synovial lipoma of the knee joint.
