BACKGROUND: Recently, according to many studies, variable factors have been known to be associated with physical fitness. The factors such as obesity and inactivity are associated with poor physical fitness, but regular exercise is associated with good physical fitness. In our country, these studies are not yet reported. And so, this study was designed to investigate the factors associat,ed with physical fitness. METHODS: From May 1st, until July 30th 1996, we recruited the 411 subjects who visited the Health Promotion Center at Seoul National University Hospital. Data related to sex, age, exercise, job, cigarette smoking, alcohol consumption were obtained by self-administered Questionnaire. Obesity index was calculated by the percentage of standard body weight. And VO2max were obtained by submaximal bicycle ergometer test. High level exercise group was defined as the persons who had taken exercise more than 3 times a week and 20 minutes per session, and moderate exercise group was defined as the persons who had taken exercise one or two times a week and 20 minutes per session, and sedentary group was defined as the persons who had taken exercise more than 20 minutes less than one time per week. RESULTS: The subjects were 230 males(56%), total numbers were 411. The results were as follows. Compaired to women and nonexercise group, men and exercise group had high VO2max(p<0.005). The relationship between VO2max and age showed negative, and the VO2max of obese group(obesity index>_120) was greater than that of nonobese group. Any significant relationships between VO2max and job, disease were not found. In multiple regression analysis, significant relationships between VO2max and age, sex, exercise type, and obesity index were observed(p<0.01). CONCLUSIONS: We concluded that there were significant relationships between VO2max and obesity index, exercise group.

BACKGROUND: Numerous metatarsal osteotomies have been developed for the treatment of Freiberg's disease. The purpose of this study was to evaluate the clinical outcomes of modified Weil osteotomy in the treatment of Freiberg's disease. METHODS: From November 2001 to July 2008, nineteen patients (twenty feet), treated surgically for Freiberg's disease, were included in this study. The average age of the patients was 33.6 years (range, 17 to 62 years), the mean follow-up period was 71.6 months (range, 41 to 121 months). Clinical outcomes were evaluated according to visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) lesser metatarsophalangeal-interphalangeal scale, the patients' subjective satisfaction and range of motion (ROM) of metatarsophalangeal (MTP) joint. In the radiologic evaluation, initial metatarsal shortening by Freiberg's disease compared to opposite site, metatarsal shortening after modified Weil osteotomy compared with preoperative radiography and term for radiologic union were observed. RESULTS: VAS showed improvement from 6.2 +/- 1.4 to 1.4 +/- 1.5 at last follow-up (p < 0.0001). Points of AOFAS score increased from 63.3 +/- 14.9 to 80.4 +/- 5.6 (p < 0.0001). ROM of MTP joints also improved from 31.3 +/- 10.1 to 48.3 +/- 13.0 degrees at last follow-up (p < 0.0001). According to Smillie's classification system, there was no significant improvement of VAS, AOFAS score and ROM between early stages (stage I, II, and III) and late stages (stage IV and V). Out of twenty cases, nineteen (95%) were satisfied, reporting excellent or good results. CONCLUSIONS: Modified Weil osteotomy is believed to be a useful method for the treatment of Freiberg's disease, not only in the early stages but also in the late stages. It relieves pain and improves function via shortening of metatarsals and restoration of MTP joint congruency.

This study is aimed to elucidate the biological nature of the precancerous lesions and to evaluate whether the ethanol alters 3'-Methyl-4-dimethylaminoazobenzene (3'-Me-DAB) induced experimental hepatocarcinogenesis. A total of 108 Sprague-Dawley male rats were used for the experiment and divided into 6 groups according to 3'-Me-DAB and ethanol administration. Administration of the drugs were carried out daily by nasogastric tube insertion and the animals were sacrificed at different interval. A part of right lateral lobe was prepared for the histological examination. Cell kinetics of the immunohistochemical method for bromodeoxyuridine (BrdU). The administration of 3'-Me-DAB induced oval cell proliferation, hyperplastic nodule, cholangiofibrosis and carcinoma in the liver. The mean labelling indices, the percentages of BrdU labelled cells, of hepatocytes were increased by administration of 3'-Me-DAB, only to reverse after cessation of the drug (2.58 vs 0.61). The labelling indices of the oval cells were also affected by the administration and cessation of 3'-Me-DAB (11.41 vs 4.48). In contrast, the cholangiofibrosis did not decrease but were still increasing following cessation of 3'-Me-DAB administration (4.37 vs 5.17 and 8.25 vs 11.29). These finding that the hyperplastic nodule and particularly the cholangiofibrosis have an autonomous proliferative potential and are definite precancerous lesions in the experimental hepatocarcinogenesis. Short term administration of ethanol decreased the incidence of development of the precancerous lesions, but did not affect the labelling indices in all the pathologic lesions of hepatocarcinogenesis.

Background: It has been reported that steroid and lidocaine reduce inflammatory responses to endotoxin. The aim of this study is to compare the effects of lidocaine with those of steroid on inflammatory responses to Escherichia coli endotoxemia in the rabbit lung. Methods: Twenty four animals were randomly assigned to one of four groups. Group I (endotoxemic group; control, n=6): They were received E. coli endotoxin (500 microg/kg) intravenously through the ear vein and followed by saline infusion at 20 ml/kg/hr for 4 hours. Group II (steroid treated group, n=6): They were treated with steroid (30 mg/kg) intravenously just after endotoxin injection and then saline was given at 20 ml/kg/hr for 4 hours. Group III (lidocaine treated group, n=6): They were received same as the endotoxemic group and lidocaine (3 mg/kg IV bolus, then continuous infusion at the rate of 2 mg/kg/hr) was administered with saline at 20 ml/kg/hr for 4 hours. Group IV (steroid & lidocaine treated group, n=6): They were received same as the endotoxemic group and after endotoxin infusion, steroid (30 mg/kg) and lidocaine (3 mg/kg IV bolus, then continuous infusion at the rate of 2 mg/kg/hr) was administered intravenously with saline. Numbers of neutrophils and monocytes in the samples of peripheral blood and lung tissue were counted and compared to evaluate the anti-inflammatory effect of drugs. Results: The group II, III, and IV showed significant attenuation of inflammatory responses compared to group I in the rabbit lung(P<0.05). But there were no significant differences among group II, III, and IV. There was no additive effect between steroid and lidocaine. Conclusion: These results suggest that lidocaine could be used as an alternative drug to steroid for its anti-inflammatory effects and cost-effectiveness.

7.p16INK4A and p15 INK4B Gene Alterations in Primary Uterine Cervical Carcinoma Tissues and Cervical Carcinoma Cell Lines.
Journal of the Korean Cancer Association 1998;30(5):1044-1052
PURPOSE: Alterations of the p15(INK4B) and p16(INK4A) gene which are separated by 25 kb on chromosome 9p21 have been reported in various tumor derived cell lines and primary tumors, but the role of these genes in cervical cancer is unknown. MATERIAL AND METHOD: To determine the frequency of deletions and point mutations of these genes in human cervical cancer, we examined 57 primary tumors and matched normal tissues, and 3 cervical cancer derived cell lines. All the tumor tissues and cell lines were human papil- INK48 lomavirus (HPV)-positive. Deletions or point mutations of exon 2 of the pl5 gene and exons 1, 2, and 3 of the p16(INK4A) gene were examined by polymerase chain reaction (PCR) and direct sequencing, respectively. RESULT: Our data indicate no evidence for intragenic homozygous deletion or point mutation in the cervical cancer or cervical cancer derived cell lines. INK48 INK4A CONCLUSION: Deletions or point mutations in the p15 or p16 gene may not be required for the development of HPV-positive cervical cancer or for establishment of cervical cancer cell lines.

8.Determinants of Effective Dose of Thiopental Sodium, Propofol and Etomidate in Elderly.
Korean Journal of Anesthesiology 2000;38(2):231-236
BACKGROUND: Many drugs are commonly administered according to total body weight or age basis. However, drugs are primarily distributed to the lean body mass. This study was undertaken to find out the best determinant for drug requirements during induction in elderly. METHODS: Forty-five ASA 1 to 3 male and female patients older than 65 years scheduled for elective surgery were divided into 3 groups and received thiopental sodium 62.5 mg/min (group T, n = 15), propofol 25 mg/min (group P, n = 15), or etomidate 5 mg/min (group E, n = 15) respectively. Kendall's tau test for correlations was used to describe the relationship between drug requirements for induction and total body weight, lean body mass determined by Weisburg's modification of Gubner's formula, ideal body weight calculated by Devine's method, and body surface area. RESULTS: Loss of consciousness was obtained with a thiopental sodium dose of 128.4 +/- 29.3 mg, propofol 59.8 +/- 13.6 mg, and etomidate 9.8 +/- 1.4 mg. Kendall's tau correlation test showed that requirements of drugs were related to lean body mass (group T, r = 0.490*, group P, r = 0.433*, group E, r = 0.493*, global P < 0.05) and ideal body weight (group P, r = 0.426*, group E, r = 0.434*, p < 0.05), but not to total body weight or body surface area. CONCLUSIONS: Our results indicate that drug requirements for induction of anesthesia correlate better with lean body mass and ideal body weight than with total body weight or body surface area in elderly patients.
