The purpose of this study was to assess the influence muscle mass has on blood concentration changes during progressive arm and leg exercise. Eight male subjects with a mean (±SD)age of 23±3.1 yr and weight of 70.2±2.7kg, were randomly assigned to complete either arm or leg exercise test using modified Body-Guard Ergometer 990. The alternate activity was performed within 2 weeks. Especially percent changes in blood and plasma volumes were calculated using values Hct(Van Beaumont et al. :1972) and Hct-Hb (D.B. Dill et al. :1974) Linear regression equations were calculated and compared for differences between slopes and intercepts when contrasting arm and leg exercise. The results obtained from this study were as follows: 1. At same level of oxygen uptake, a relative larger percentage decrement of plasma volume occurred for arm compared with leg exercise. 2. There was a linear relationship between the amount of plasma volume lost from the vasculature and the exercise intensity for both arm and leg exercise. 3. Plasma efflux during exercise was related to the mean arterial pressure which was directly related to the relative intensity of the exercise.
The recombinant pseudorabies virus major capsid protein (rMCP) was produced by expression of the MCP gene in Sf-9 cell using baculovirus transfer vector system. Following evaluation of the immunochemical properties of the rMCP, the immunogenicity of the recombinant subunit protiens were investigated in guinea pig and swine to obtain the preliminary guide line for the subunit vaccine using rMCP and gP50. It was proved that ultrasonication and 30% ammonium sulfate was most efficient to concentrate and purify the protein. The rMCP was safe in mice, guinea pigs and piglets. In guinea pigs, rMCP mixed with various adjuvants induced substantial degree of serum neutralizing antibody titers, but revealed incomplete protecivity against challenge. In swine, the combination of rMCP and gP50 showed the higher serum neutralizing antibody titers and cellular immune responses than rMCP alone. However, the protectivity was lower in comparison with the commercial gI-deleted inactivated vaccine. We expect these results to contribute to characterization of MCP gene of Korean isolate of PRV and to ultilize as preliminary information for prodution and evaluation of PRV recombinant subunit vaccines.
In this study gene encoding structural proteins of a CPV isolate was cloned and saquenced to elucidate the molecular genetical properties of the canine parvoviruses isolated from the field. Six recombinant plasmids of pEP3, p1471, p2070, pEP069, pEP338 and p14711p were constructed from the map positions 22 to 98 of RF DNA to clone the VP1 and VP2 genes of CPV-V20. Sequentialy the gene comprising 3780 nucleotides were sequenced by dideoxy chain termination method. When nucleotide sequence of gene encoding the structural proteins of CPV-V20 was compared with those of other strains, CPV-N, CPV-d and CPV-780929 published previously. DNA homologies to CPV-V20 were 99.87% with CPV-NM, 99.73% with CPV-d, 96.85% with CPV-780929 AND 98.4% with FPLV-Carl, respectively. The DNA sequence data of CPV-V20 showed seven point mutations and also deletion of 135 nucleotides from the nucleotide position 4745 to 4879 located in the 3-noncoding region of CPV-N.
The purpose of this study was to determine the effectiveness of creatine ingestion during weight training on the dynamic muscular strength and change of body composition in women athletes.

Canine parvovirus(CPV) is a member of autonomous replicating parvoviruses and is aetiologically associated with enteritis and mycoarditis in puppies. The capsids of CPV are composed of three structural proteins: VP1, VP2 and VP3. The VP2 protein is the major component of capsid. The VP2 gene of a canine parvovirus. V20 strain isolated in Korea was cloned into baculovirus expression vector, and subsequently the VP2 protein was expressed by a recombinant baculovirus under the control of polyhedrin promoter. The recombinant VP2 protein expressed in Spodoptera frugiperda 9(Sf9) cells was detected by haemagglutination(HA) test and immunofluorescent antibody assay. Molecular weight of the recombinant VP2 protein expressed was estimated as 64Kd when tested by immunoprecipitation test using anti-CPV monoclonal antibody. In haemagglutination inhibition(Ⅲ) test. 8 HA units of the recombinant VP2 protein antigen was successfully utilized to determine a level of antibody against CPV in various positive sera. The recombinant VP2 protein showed also the capability to form virus like particles similar in size and appearance to the CPV virions.
I analyse the contextual dependency between labour movement and political movement in the case of the Busan and Masan Areas' democratic movement of 1979. This paper focuses on the concept of political and industrial opportunity structure as a determinant of labour movement an political movement. Busan and Masan Areas' democratic movement depended contextually on the growth and development of the democratic union movement of 1970s. The success of the political movement opened the political opportunity structure of labour movement of 1980 in Korea. At same time Korean labour movement was contextually determined by the political movement as such Busan and Masan Areas' democratic Movement. In conclusion, the success of labour movement will depend on how it use the political opportunity structure in Korea.
The purpose of this study was to examine the short-term effects of aerobic exercise on psychological emotion. 16 female college students who were divided into two groups, such as experimental (n=8), and control group (n=8) participated in a single-session experiment during which they carry out two 8-min trials of high-load exercise and two 8-min trials of low- load exercise. A Monark Type 864 bicycle ergometer by cycling at 50rpm against a load of 25w or 100w. Emotion was assessed using an adaptation of the POMS (McNair et al., 1981). The conclusions obtained from this study were as follows ; 1. High-load exercise leads to increase in tension/anxiety and fatigue, whereas positive emotion changes were seen following low-load exercise only. 2. No group differences in emotion responses were observed.
We analysed 404 patients with primary lung carcinoma who were treated at Soonchunhyang University Hospital from July, 1985 to september, 1993 in order to investigate the survival rate and epidemiolgical properties of primary lung cancer. They were 330 males and 74 females. The most prevalent decade was seventh. In terms of cell type, the squamous cell was 225 patients (55%), and adenocarcinoma, small cell, mixed type was 21%, 19%, 4%, respectively. Among non-small cell lung carcinoma, stage Ⅲa was the most prevalent one(92%). In case of small cell carcinoma, the limited stage was 64%. The 12-, 24-, 36- month survival rate of total patients was 57%, 31%, 22%, respectivley and median sruvival time was 15 months. The 36-month survival rate tended to be longer in non-small cell lung carcinoma than that of small cell lung cancer, but there was no difference between two groups, statistically. In non-small cell carcinoma, The 36-month survival rate and meidan survival time were longer in the stage Ⅰ and Ⅱ than those of Ⅲa, Ⅲb, Ⅳ (80% versus 38%, 22%, 0%, p<0.05). According to involvement of lymph node, the 36-month survival rate was longer in NO and N1 than those of N2, N3 (61.9%, 48.7% versus 17.7%, 17.3%, p<0.05). In small cell carcinoma, The 36-month survival rate and median survival rate were higher and longer in limited stage than those of extensive stage(16.1% and 13 month vs 10% and 8 month, p<0.05). In conclusion, we report here the incidence of primary lung carcinoma and the survival rate of paients with primary lung carcinoma who were treated in Soonchunhyang University Hospital.
The purpose of this study was to evaluate the amount of creatine present in the urine of exercising athletes ingestion with a dosage specific to their lean body tissue and at an amount approximating the maintenance dosage recommended by distributors of creatine ingestions. Male subjects(n=32) who were weight lifters(n=16) and soccer players(n=16) between the age of 19 and 25 years served for this study. In a double-blind, ramdomzed block design, 8 weight lifters and 8 soccer players were assigned to either the creatine ingestion or placebo group. As the method of urine analysis, high-performance liquid chromatography (HPLC) were carried out on a Gilson HPLC with HPLC system controller software. An SPSS-pc 2-way ANOVA procedure was used to determine if significant differences occurred between the ingestion and placebo groups for creatine and pre-to post changes. The conclusions obtained from this study were as follows: 1. In 24-hour, 48% of the ingested creatine was excreted with urine. 2. When ingesting with dosages of 0.1g/㎏ lean body mass or between 7~8g at a time, about half or the ingested creatine got excreted.
