The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

김치 발효 숙성기간을 연장하고 신선도를 오랫동안 유지 할 수 있는 김치발효 starter의 개발을 목적으로 최적숙성기에 있는 김치로부터 bacteriocin생성능이 없는 유산균을 분리하여 동정하였으며, bacteriocin생성능이 우수한 L.acidophilus 88을 융합시키기 위해 electrofusion에 대한 최적 조건을 검토하였다. 분리균주는 Lactobacillus속으로 동정되어 Lactobacillus sp. JC-7이라 명명하였다. Electrofusion에 의해 생성된 융합주를 식별하기 위해 streptomycin(2.5㎎/ml)에 내성을 나타내는 Lactobacillus sp. JC-7변이주와 kanamycin(600㎍/ml)에 내성을 나타내는 L.acidophilus 88변이주를 분리하였다. Electrofusion을 100V/㎝, 120msec(72ohms,1670 capacitance) 에서 수행했을 때 융합효율이 가장 양호하였으며 전기장의 세기와 시간이 중가할수록 융합 효율이 현저히 감소하였다. 2가 양이온은 농도가 중가할수록 대체적으로 융합효율을 감소시키는 경향을 나타내었으나 1mM MGCl_2에서는 대조군에 비해 융합효율이 약간 증가하였다. PEG매개에 의한 융합법의 융합효율을 비교한 결과, 융합효율은 chemical fusion<electrofusion<electrofusion+20% PEG순을 나타내었다. Evaluation of Optimum Conditions for the Electrofusion between Lactobacillus sp. JC-7 Isolated from Kimchi and Lactobacillus acidophilus 88. Young-Bae Jo, Hyun-Jung Choi, Hyung-Suk Baik and Hong-Ki Jun*. Department of Microbiology, Pusan National University, Pusan 609-735,Korea-A lactic acid bacterium was isolated from kimchi. The isolated strain was identified as the genus Lactobacillus thrugh its morphological characteristics and named as Lactobacillus sp. JC-7. The optimum conditions for the electrofusion between streptomycin(2.5㎎/ml)resistant mutant of Lactobacillus acidophilus 88 and kanamycin(600㎍/ml) resistant mutant Lactobacillus sp. JC-7 were evaluated. The highest number of fusants were obtained at a capacitance value of 120msec(1670㎌), a field strength of 100V/㎝,and a pulse controller setting of 72Ω. The potimum pH of elecroporation buffer was 7.5 and the concentration of divalent cation was 1mM MG^2+. Electrofusants were efficiently obtained by addition 20% polyethylene glycol to electroporation buffer. The yield of fusion was better than that of using polyethylene glycol mediated chemical induction.

Gastric metastasis from breast cancer is rare and only six cases have been reported in Korea. Colon metastasis is more rare than gastric metastasis. We report a 63-year-old woman with gastric and colon metastases of invasive lobular carcinoma of breast. She was diagnosed as right breast cancer, received right modified radical mastectomy 10 years ago and has been treated with chemotherapy and hormone therapy. Investigating for melena and a small caliber of stool, we found gastric and colon metastases. The diagnosis of metastatic breast cancer was made through gross pathologic and immunohistochemistry staining. We report a case with gastric and colon metastases from breast cancer and a review of the associated six case reports in Korea.

진공증착방법으로 제작한 Ni_53-Fe_47 박막에 관한 신형전류자기 기전력효과의 전류와 자장 방향이 만드는 각 θ 의존성이, 자기저항효과의 cos 2θ, Hall 1 효과의 경우 sin 2θ로 관측되고, 이 효과의 자장에 의존하는 전압변화율이 자기저항효과와 비교할 때 차수가 다르게 큰 것이 조사된다. 이 효과가 2 Carrier형 모델로 이해할 수 있음을 이론적으로 확인된다. A new Galvanomagnetic electromotive force effect of Ni_53-Fe_47 thin films is studied. The dependence of this effect on θ, angle between the current and the magnetic field, is found to be the form of sin 2θ, in contrast with that of the magnetoresistance effect cos 2θ and that of the Hall effect sin θ. Property of this effect is that the rate of the voltage variation depending on the magnetic field is extremely large as compared with the magnetiresistance effect. It is theoretically confirmed that this effect is well understood on the basis of the two carrier types model.

Diagnosis of Clonorchis sinensis requires specific proteins as antigens and it has been developed by using a rapid detection kit which identify circulating antibodies. In this study during Namseoul University Health/Medicine Care Service conducted in October 2010, with the residents in Wondeok-eup Samcheok Kangwon-do, the rapid diagnosis of C. sinensis infections was performed and patients' blood sera were analyzed. From 12 patients' sera of total 83, antibodies to C. sinensis were detected. According to the patients' sera analysis, about 73% of Total bilirubin, 40% of Cholesterol and 40% of Creatinine were abnormally exhibited. In the C. sinensis-positive sera detected by a rapid diagnostic kit, about 92% of Total bilirubin, 33% of Cholesterol and 50% of Creatinine were abnormally exhibited. According to analysis of blood cells, there was no abnormal result except for Hematocrit. In particular, high Eosinophil which means high incidence of C. sinensis infection was not observed. Taken together, it implied that the positive diagnosis of clonorchiasis would be previous infections of C. sinensis and its patients recovered from clonorchiasis have still antibodies in their sera. In addition, it also suggested that C. sinensis-positivity by the rapid diagnostic kit be not consistent with the present infections of C. sinensis.

Fries rearrangement has been known as highly useful reaction for the synthesis of ortho-or para-hydroxyacylbenzene from phenyl ester in the presence of Lewis acid catalyst. Conventionally, aluminum chloride was used as catalyst. For obtaining N-(4-acetyl-3-hydroxyphenyl)acetamide, 3-acetamidophenyl acetate was subjected to Fries Rearrangement reaction using aluminum chloride. Although the desired N-( 4-acetyl-3-hydroxyphenyl)acetamide was obtained, yield was very low. In addition, regioisomer N-(2-acetyl-5-hydroxyphenyl)acetamide and unexpected N-(2-methyl-4-oxo-4H-chromen-7-yl) acet-amide were obtained. NMR study and conversion to known compollnds confirmed the substitlltion pattern of these phenylacetamides and the structure of chromen-4-ones. Under this Fries Rearrangement condition, formation of chromen-4-one was newly discovered.
