<P><I>Conclusion:</I> Gankyrin seems to be a better biomarker for cholesteatoma compared with Ki-67. <I>Objective:</I> Gankyrin is an oncoprotein, and occurs in cancers but not in benign diseases. The goal of this study was to compare expression of gankyrin, p53, and a proliferation marker (Ki-67) in cholesteatoma and retroauricular skin (RAS), and to evaluate their significance as clinical parameters. <I>Methods:</I> The levels of expression of gankyrin, Ki-67, and p53 in 10 cholesteatoma and 10 paired samples of normal RAS were evaluated by immunohistochemical staining and Western blot. The results were compared with clinical profiles to investigate a correlation. <I>Results:</I> The expression of gankyrin, Ki-67, and p53 proteins was observed in both basal and suprabasal layers of cholesteatoma. The intensity of gankyrin expression was ‘positive’ in two cases (20%) and ‘strongly positive’ in eight cases (80%); p53 expression in the suprabasal layer was ‘positive’ in 70% of cases; and the Ki-67 staining was ‘focal’ in 80% of cases. In RAS, these proteins were expressed dominantly in the basal layer. Western blot analysis showed that the gankyrin band was more intense in cholesteatoma than in RAS for three of four cases (<I>p</I> < 0.05). However, there was no significant difference in the expression of gankyrin, Ki-67, and p53 according to clinical variables.</P>

Objective: This study aims to analyze that specific prognostic factors such as Ki-67 value, histologic grade, pathology type, and cancer stage can affect controlled ovarian stimulation outcomes(COS) for fertility preservation in women with breast cancer. Methods: This retrospective cohort study included 92 patients with breast cancer aged 21-44 who underwent COS from August 2012 to April 2020, excluding patients with previous gonadotoxic therapy history. All COS cycles were conducted letrozole-combined random start GnRH antagonist protocol. COS outcomes were compared according to prognostic factors;Ki-67 (< 30% vs. ≥ 30%), histologic grade (low vs. high), and pathologic type (intraductal carcinoma(IDC) vs. triple-negative breast cancer(TNBC)), and cancer stage (early (I, II) vs. advanced (III, IV)). Multivariate analysis was also conducted to find any parameter that can impact over 10 mature oocytes acquisition. Results: Among the 92 patients, 42 were Ki-67≥30% compared to 49 of Ki-67<30%. The number of oocytes, and initial mature oocytes were comparable between Ki-67<30% and ≥30 group. The maturation rate was significantly higher in Ki-67≥30% group than Ki-67<30% group (57.4±36.8% vs. 44.8±28.3%, p=0.041). The same results were drawn when divided according to IDC or TNBC. The maturation rate was significantly higher in TNBC than the IDC group (73.0±17.6% vs. 47.0±28.1% p=0.001). However, the histologic grade or stage did not show any difference in COS outcomes between high and low grade or early and advanced stages. With multivariate analysis, age and AMH are parameters associated with the acquisition of over 10 mature oocytes (OR 0.863, 95% CI [0.755-0.987], OR 1.408, 95% CI [1.145-1.732], respectively). Conclusion: Either Ki-67 or pathologic type can be a potential reliable marker for predicting COS outcome, especially maturation rate. Further study with larger sample size with specific conditions is necessary to clarify the correlation between breast cancer prognostic factors and COS outcomes.

This study compared the effects of two types of pelvic compression belts on hip extensor muscle strength and leg raise heaviness in individuals with and without low back pain. Subjects with (n=15) and without low back pain (n=45) were enrolled in this study. The degree of subjectively perceived heaviness during prone hip extension (PHE) test was measured on a 6-point scale. The isometric strength of the hip extensor muscles was measured with 20°of PHE and the knee in full extension. Muscle strength was measured before the use of the pelvic compression belt, and then after the use of elastic and non-elastic pelvic compression belts in random order. All measurements were made on the side that the subject perceived as having greater difficulty during PHE. Using descriptive analysis and repeated-measures analysis of variance, we compared the effects of pelvic compression belt use on hip extensor muscle strength in individuals with and without low back pain. There were no significant differences in hip extensor strength and leg raise heaviness level between subjects with and without low back pain with the use of the two types of pelvic compression belts. With the use of the two types of pelvic compression belts, hip extensor strength was significantly increased in both subjects (p<.01). There was no significant difference between the two types of compression belts concerning the effect on hip extensor strength. Both elastic and non-elastic pelvic compression belts helped to improve hip extensor strength in individuals with low back pain

通貨主義(Monetarist) 인플레이션 理論 一考察

玄紋吉,都基偵 東亞大學校 1995 東亞論叢 Vol.32 No.-

The purpose of this study is to summarize and evaluate the "Monetarist Inflation Theory". The beginning of the new debate in inflation theory can be characterized by the attempt to explain the inflation proces as 'causal'. Does inflation orginate in the labor market or can it be explained by the rate of growth of the money? Later, with acceleration of inflation, the emphasis shifted to explaining inflationary expectations. The treatment of expectations distinguishes the new inflation models from the traditional theory. Monetarism as discussed in Chapter I is defined by the following four propositions : 1. Stability of the private sector. The private sector of he economy is inherently stable. The economic system returns automatically to a full-employment equilibrium after a disturbance ; the unemployment rate returns to the 'natural' rate. 2. Long-run neutrality of money. Any rate of growth of th money supply is compatible with a full-employment equilibrium, although different rates of inflation result. 3. Acceptance of the short-run Phillips curve. A change in the rate of growth of the money supply first alters the rate of real economic growth(and hence the unemployment rate). In the long run this real effect vanishes and there remains only a permanent increase in the trend rate of inflation(acceleration theorem). 4. Dislike of activist economic policy. There is dislike of activist demand management policy, either monetary or fiscal, and preference for long-run monetary policy "rules" or prestated 'targets'. The stability postulate is not at the head of the list by chance. Actually, the assumption of an inherently stable economic system is a presupposition of monetarist theory. The stability of the market as an economic system is assumed, not proven : in particular, it is asserted that the labor market is always approaching equilibrium; that is, the rate of unemployment is equal to the natural rate, which represents only frictional unemployment. On the basis of the stability postulate, monetarism excludes the possibility of a Keynesian underemployment equilibrium characterized by an excess supply of goods and labor. Here Monetarism steps across the bundaries of pure economic theory and assumes ideological aspects. The second theorem of monetarism simply formulates the long-run quantity theory. In the steady, when all variables are correctly anticipated, the rate of growth of the money supply completely determines the rate of inflation. In other words, a full-employment equilibrium is indenpendent of a fully anticipated rate of inflation. Whereas the long-run quantity theory is relatively trivial, the third theorem of monetarism has greater importance. One can designate this as short-run quantity theory, which maintains that an acceleration in the rate of growth of the money supply temporarily raises the rate of real economic growth and, hence, reduces te rate of unemployment. The subsequent inflation leads to an adjustment in the economic system. During this adjustment process, the rate of real economic growth again returns to the orginal rate. Thus, the acceleration in real growth achieved through a faster rate of money growth is only temporary. Brunner labeled this principle the 'acceleration theorem'. Most monetarit authors, such as Friedman, Brunner, and Laidler, use this principle theorem plays a central role in the analysis of the short-run adjustment process. In that respect, it figures prominently in the 'standard' monetarist model. The main aspect of proposition 4 is the rejection of discretionary fiscal and monetary policy. The main policy issue, therefore, is to replace activist economic policy by rules like the constant growth rate rule for the money supply or constant rules for fiscal policy. Monetarists, on the other hand, contend that the orgins of inflation are always excessive monetary expansion by the authorities. Monetarists would then accept the dictum put forward by Friedman that : "Inflation is always and everywhere a monetary phenomenon in the sense that it is and can be produced only by a more rapid increase in the quantity of money than in output."

Obesity is growing problem in Korea. We had a case of bariatric surgery during gastric cancer operation. Patient was 29 year old Korean lady with early gastric cancer located in the lesser curvature side of the middle 1/3 of the stomach. Her body weight was 89 kg, height 163 cm, and thus body mass index was 33.5 kg/m2. Preoperative blood pressure was 130/90 mmHg, hemoglobin 12.9 g/dL, total lymphocyte count 3,280/mL, serum albumin 4.3 g/dL, CEA 1.1 ng/mL, CA 19-9 9.1 ng/mL, and alpha fetoprotein 2 ng/mL. Another associated disease was right thyroid follicular neoplasm. The chest X-ray was normal. After IM injection of 2,500 units of heparin 30 minutes before the induction of general anesthesia, she received curative subtotal gastrectomy and Roux en Y gastrojejunostomy when a malabsorption loop of 120 cm jejunum was incorporated between the Treitz ligament and the end to side jejuno-jejunostmy site at May 29th 2006. Her postoperative course was uneventful except a minor wound seroma and the elevations of serum amylase(up to 4 folds) and lipase(up to 2 folds). She lost her body weight 9 kg in 5th, 21 kg in 7th, and 27 kg in 10th postoperative months to became 61.5 kg. On follow up exams in July 2008, she gained 4 kg to overcome her weakness and fatigue. From the above result, the incorporation of a malabsorption loop during reconstruction phase of gastric cancer operation was a good option for obese gastric cancer patients especially in cases of early gastric cancer.

This experiment was carried out to protect drops of feed intake should be plural prepartum and postpartum to reduce metabolic diseases after calving to know how feeding systems, which is divided as a low quility, a high quility and total mixed rations(TMR), affects on postpartum productivity of Holistein cows. Three diets (low or high quality forage separately fed with concentrate and TMR containing high quality roughage) were fed to 21 cows from 3 weeks prepartum to 8 weeks postpartum to examine their effects on the productivity of cows. DM intakes was noticed significantly higher with TMR (17.11kg/day) than low- quality (13.48 kg/day) and high-quality forage (13.10kg/day). TDN and CP intakes were also higher with TMR compared to other experimental diets. Mean daily milk yield was non-significant among the cows fed different diets. Blood non-esterified fatty acids(NEFA) content was higher in cows fed low-quality or high-quality forage separately with concentrate compared with those fed TMR. The results concluded that TMR feeding to transitional cows is better than feeding the low or high quality forage separately for their health and productivity. 본 시험은 분만 전 3주부터 분만 후 3주까지 전환기라고 지칭되는 시기의 젖소들에 대한 대사적 변화를 최소화하기 위한 방법으로 사료 섭취량 저하를 방지하고 분만 후 대사성 질병의 발생을 줄이기 위한 목적으로 수행되어졌다. 대사성 질병에 관여하는 주요 요인으로는 건물섭취량, 혈중 glucose 함량, NEFA 함량, 반추위 환경, 면역 등인데, 분만 전·후 Holstein 젖소에 사료급여 형태를 조·농분리(저질 조사료와 양질 조사료 급여구) 및 TMR로 다르게 하였을 때 사료섭취량 변화와 혈중 NEFA 및 glucose 함량 변화를 측정하고 분만 후 젖소의 생산성에 미치는 영향을 구명하기 위하여 수행하였다. 처리별 사료건물 섭취량은 저질 조사료 조·농 분리, 양질조사료 조·농 분리, TMR 급여구에서 각각 13.48, 13.10, 17.11kg으로 TMR 급여구에서 유의성 있게 높았으며(P〈0.05), TDN 섭취량은 처리구별 각각 7.35, 7.19, 5.66kg으로 처리간에 차이가 없었다(P〉0.05). 신체충실지수(BCS)는 저질조사료구에서는 3.03이였으며, 양질 조사료구와 TMR 급여구에서는 각각 3.19, 3.16이었다. 분만후 1주부터 5주까지 측정한 평균 산유량은 저질조사료 조·농 분리, 양질 조사료 조·농 분리, TMR 급여구에서 각각 34.1, 35.1, 35.6kg 였으며, 분만 후 4∼5주에 최고 비유기에 달했다. 처리별 평균 유지율은 저질 조사료 조·농 분리, 양질 조사료 조·농 분리, TMR 급여구에서 각각 3.74, 3.68, 3.95%였다. 혈청내 NEFA 함량은 저질 조사료 조·농 분리, 양질 조사료 조·농 분리, TMR 급여구에서 각각 744.4, 381.8,266.7μEq/L로 처리간에 큰 차이를 보여 양질 조사료 급여와 TMR 급여시 혈중 NEFA 함량이 저질 조사료 급여에 이해 유의성 있게 낮았다(P〈0.05). 혈청내 glucose함량은 저질조사료 및 양질 조사료 조·농 분리, TMR 급여구에서 각각 39.3, 56.3, 62.4mg/dl로 양질 조사료 급여와 TMR 급여시 혈중 glucose 함량이 저질 조사료급여에 비해 유의성 있게 높았다(P〈0.05). 이상의 결과들을 종합해 볼 때, 분만 전 3주부터 분만 후 3주까지의 전환기 동안 사료섭취량 증가와 대사성 질병의 지표로서 혈중 NEFA 및glucose 함량 변화를 살펴 본 결과 분만 전 3주부터는 양질의 조사료나 TMR 형태로 급여하는 것이 사료섭취량 증가와 대사성 질병의 발생을 감소시킬 수 있을 것으로 사료되었다.
