A splenectomized 5-month-old calf was inoculated with cryopreserved Theileria sergenti infected blood originated from naturally infected Korean native cattle in Chonbuk district. At peak parasitemia (40.1%), blood was collected, washed, lysed and then the T sergenti merozoite was isolated by differential centrifugation. Antigenic profile of isolated T sergenti organism was analized by SDS-PAGE and western blotting techniques. Coomassie blue stained SDS-PAGE gel revealed at least twelve protein bands of approximately 14Kd, 28Kd, 30Kd, 34Kd, 36Kd, 38Kd, 41Kd, 56Kd, 66Kd, 72Kd, 97Kd and 116Kd in the merozoite homogenate. In western blot, although T sergenti antigen recognized by specific anti-T sergenti antibodies demonstrated 28Kd, 30Kd, 38Kd, 56Kd, 58Kd, 66Kd, 97Kd and 116Kd proteins. False positive reactions were also observed in normal bovine serum with T sergenti and normal erythrocytic antigens. Therefore, predominant proteins of T sergenti merozoite antigen were found to be 28Kd, 30Kd, and 41Kd proteins of molecular weights. On going studies we will analyze the relative importance of those antigens for immunity of T sergenti in Korean native cattle.

The purpose of this study was to determine whether any difference existed in craniofacial morphology between cleft children and normal subjects. Thirty three measurements of the various regions of cranium and face were obtained from lateral cephalometric radiograms in 40 cleft children(27 males, 13 females) and 40 normal subjects(23 males, 17 females) in our dental hospital from Jan. 1988 to Dec. 1995.The measurements were compared with those in control subjects who had no history of craniofacial abnormalities. The obtained results were as follows: 1. In the cranium, the cleft children had singificantly shorter posterior cranial base length(S-Ba) and total antero-posterior cranial base length(N-Ba) (P<0.05). 2. In the upper face, the cleft children had significantly shorter upper anterior facial height(N-ANS) and upper posterior facial height(Ptm'-SNL) (P<0.05). 3. In the lower face, the cleft children had significantly shorter antero-posterior mandibular length(Pog-Ar) and antero-posterior mandibular body length(Pog-Go) (P<0.05). 4. In the facial profile, the cleft children had significantly shorter total facial height(N-Me} and posterior facial height(S-Go) (P<0.05).

The purpose of this study was to obtain the cephalometric maxillofacial soft tissue measurements, and to define the differences that exist between males and females on the soft tissue profile who had normal occlusion in mixed dentitions. For the object of this study, cephalometric radiographs were obtained from the centric occlusion with the relaxed lip position. Copper filter was designed to obtain both hard and soft tissue structure on the same film. The subjects consist of 100 males and 100 females from 8 to 12.4 years with the normal occlusion and acceptable profiles. The author measured facial depth, vertical height from the tissue profiles in the mixed dentitions. The significant test compare males with females. The following results were obtained from the study 1. In facial convexity, much more larger females than that of males. 2. Inclination of the lip posture were more larger in maxilla (male) and in females more larger in the mandible. 3. The thickness of soft tissue were thicker in males, the height of nose were more prominent in females. 4. There were no significant differences in both sexes.

Dietary and other factors affecting serum lipid levels of 103 rural women aged 30-76 years were assessed. Data for dietary intakes were obtained by 24-hour recall method. Body weight, height and blood pressure were measured and BMI was calculated from the anthropometric data. Serum samples were collected and analyzed for TG and lipoprotein fractions. Relation of the factors with serum lipid concentration was analyzed by Pearson's correlation coefficient(r). The results were summarized as follows: The weight, hight and BMI of the subjects were 56.8kg, 152.4cm and 24.5k/==, respectively. 31.8% of the subjects under 50 years of age($\leq$49yr group) and 61.0% of the subjects from 50 years up(==50yr group) were classified as hyperlipidemia. Most of the subjects had normal blood pressure but 8.5% were hypertensive. Total food intake of hyperlipidemic subjects was more than those of normal subjects in both age groups. Nutrients intake also tended to be higher in hyperlipidemic subjects of $\geq$50yr group. Intake of some foods like nuts, milk, or meat affected serum lipid profile even though the effects was somewhat different between two age groups. Body weight was positively related with serum TG and VLDL-cholesterol in $\leq$49yr group, and body weight as well as height and BMI affected serum lipid level in $\geq$50yr group. In summarization, it appeared that hyperlipidemia was a serious health problem in rural women. Hypertriglyceridemia due to sharp increase after 50 years old was remarkable and further research should be performed to determine the related factors in the near future.

[Purpose] The purpose of this study was to investigate the effects of treadmill exercise on oxidative stress in the hippocampal tissue and mitochondrial dynamic-related proteins in rats fed a long-term high-fat diet (HFD). [Methods] Obesity was induced in experimental animals using high fat feed, and the experimental groups were divided into a normal diet-control (ND-CON; n=12), a high fat diet-control (HFD-CON; n=12) and a high fat diet-treadmill exercise (HFD-TE; n=12) group. The rats were subsequently subjected to treadmill exercise (progressively increasing load intensity) for 8 weeks (5 min at 8 m/min, then 5 min at 11 m/min, and finally 20 min at 14 m/min). We assessed weight, triglyceride (TG) concentration, total cholesterol (TC), area under the curve, homeostatic model assessment of insulin resistance, and AVF/body weight. Western blotting was used to examine expression of proteins related to oxidative stress and mitochondrial dynamics, and immunohistochemistry was performed to examine the immunoreactivity of gp91phox. [Results] Treadmill exercise effectively improved the oxidative stress in the hippocampal tissue, expression of mitochondrial dynamic-related proteins, and activation of NADPH oxidase (gp91phox) and induced weight, blood profile, and abdominal fat loss. [Conclusion] Twenty weeks of high fat diet induced obesity, which was shown to inhibit normal mitochondria fusion and fission functions in hippocampal tissues. However, treadmill exercise was shown to have positive effects on these pathophysiological phenomena. Therefore, treadmill exercise should be considered during prevention and treatment of obesity-induced metabolic diseases.

Purpose: This study was aimed to identify the difference of the self-efficacy and the health promoting behaviors between obese and normal-weight middle school students. Method: Data were collected from a convenient sample of 360 middle school students (180 normal-weight students and 180 obese students) in Pusan from November 22nd to December 20th. 2000. based on self-report questionnaires. The following instruments were used in the study after being reconstructed by the researcher with the consultation of experts and the literature review: General Self Efficacy Scale(Sherer et al.. 1982). and Health Promoting Lifestyle Profile (Walker. Sechrist & Pender. 1987). The data were analyzed with descriptive statistics, chi-square test. and t-test and Pearson's correlation coefficient. Results: 1. There were significant differences in father's obesity (p=.014) mother's obesity (p= .007), sibling's obesity (p=.00l), and school record (p=.001) between obese and normal-weight students. 2. There were statistically significant differences in the score of self-efficacy between the obese and normal-weight students (p=.0001) 3. There were statistically significant differences in health promoting behavior (p= .000) and in six sub-i terns: personal relationship (p =.000), exercise (p=.001), responsibility for health (p=.003), stress management (p = .015), self-actualization (p =.043) between the obese and normal weight students. 4. There were very statistically significant negative correlations between obesity and the self-efficacy (r=-.19. p<.001), health promoting behavior (r=-.18. p<.001), specifically personal relationship(r=-.20. p<.001), stress management (r=-.12. p<.05), responsibility for health (r=-.15. p<.01), and self-actualization (r=-.14. p<.01). Conclusion: According to the above results it is concluded that self-efficacy and health promoting behavior influence the obesity of middle school students. Therefore I recommend adding programs that can lead to improve self-efficacy and health promoting behavior to the obesity prevention programs for middle school students.

Purpose: The proton used in proton therapy has a characteristic of giving a small dose to the normal tissue in front of the tumor site while forming a Bragg peak at the cancer tissue site and giving up the maximum dose and disappearing immediately. It is very important to verify the proton arrival position. In this study, we used the off-line PET CT method to measure the distribution of positron emitted from nucleons such as 11C (half-life = 20 min), 150 (half-life = 2 min) and 13N The range and distal falloff point of the proton were verified by measurement. Materials and Methods: In the IEC 2001 Body Phantom, 37 mm, 28 mm, and 22 mm spheres were inserted. The phantom was filled with water to obtain a CT image for each sphere size. To verify the proton range and distal falloff points, As a treatment planning system, SOBP were set at 46 mm on 37 mm sphere, 37 mm on 28 mm, and 33 mm on 22 mm sphere for each sphere size. The proton was scanned in the same center with a single beam of Gantry 0 degree by the scanning method. The phantom was scanned using PET-CT equipment. In the PET-CT image acquisition method, 50 images were acquired per minute, four ROIs including the spheres in the phantom were set, and 10 images were reconstructed. The activity profile according to the depth was compared to the dose profile according to the sphere size established in the treatment plan Results: The PET-CT activity profile decreased rapidly at the distal falloff position in the 37 mm, 28 mm, and 22 mm spheres as well as the dose profile. However, in the SOBP section, which is a range for evaluating the range, the results in the proximal part of the activity profile are different from those of the dose profile, and the distal falloff position is compared with the proton therapy plan and PET-CT As a result, the maximum difference of 1.4 mm at the 50 % point of the Max dose, 1.1 mm at the 45 % point at the 28 mm sphere, and the difference at the 22 mm sphere at the maximum point of 1.2 mm were all less than 1.5 mm in the 37 mm sphere. Conclusion: To maximize the advantages of proton therapy, it is very important to verify the range of the proton beam. In this study, the proton range was confirmed by the SOBP and the distal falloff position of the proton beam using PET-CT. As a result, the difference of the distally falloff position between the activity distribution measured by PET-CT and the proton therapy plan was 1.4 mm, respectively. This may be used as a reference for the dose margin applied in the proton therapy plan.

The purpose of this research is to analyze the effects of aerobic exercise on body composition, cardiopulmonary function, serum lipid level and antioxidants of obese and normal college female students. The subject group was made up of 13 normal students (below 30% body fat ratio) and 12 obese students (above 30% body fat ratio). After a pretest, the subjects were given an 8-week aerobic program. Then the subjects were given a posttest and analyzed of body composition, serum lipid level, antioxidants and cardiopulmonary function after the 6th and the 8th week of the program. The program schedule was made up of 4 days per week, 60 minutes per day. Test includes B.W., subscapular and triceps subcutaneous fat thickness, change of respiratory gas, and two blood sampling before treadmill exercise and post all out state, which analyzed serum lipid and antioxidants. The subjects performed treadmill exercise starting with 4km/hr of walking and then gradually increase the speed of 1km/hr per minute until all out state. The obtained data were analyzed using SAS program. The statistical methods employed here were one-way ANOVA with repeated measure, Duncan Multiple range test, paired-t test and t-test. The test results and conclusion of this research were as follows. 1. The effects of aerobic exercise on body composition were as follows ; Percent body fat was significantly reduced 6 weeks after the program and lean body mass was significantly increased 8 weeks after the program in both groups(obese group: F=3.44 P=.044, normal group: F=3.30 P=.048). subscapular skinfold of the obese group showed a remarkable decrease after the 6th week(F=4.33 P=.021) triceps skinfold of the normal group showed a remarkable decrease after the 6th and the 8th week(F=4.55 P=.017) compared with readings before the aerobic program, the aerobic program made a bigger difference concerning body fat, lean body mass, subscapular skinfold in the obese group than in the normal group(t=2.41 P=.024, t=2.40 p=.025, t=2.43 p=.028). 2. The effects of aerobic exercise on cardiopulmonary function were as follows ; Maximal $O_2$ uptake/kg was significantly increased 6 weeks after the program in the obese group(F=3.20 P=.054), but not much difference was observed in the normal group. Maximal pulse rate was significantly reduced in both groups after 6 weeks of the program(obese group: F=2.77 P=.087, normal group: F=7.17 P=.001). 3. The effects of aerobic exercise on serum lipid level were as follows ; In a resting period, total cholesterol, Triglyceride, and LDL-cholesterol were slightly higher in the obese group than in the normal group, but HDL-cholesterol was higher in the normal group. But, with the aerobic program, total-cholesterol, Triglyceride, LDL-cholesterol were reduced gradually and HDL-choleterol got increased in both groups, but not much change was noticed in the normal group. However, in the obese group, serum HDL-cholesterol level got increased significantly(F=5.12 P=.012). 4. The effects of aerobic exercise in serum antioxidants were as follows ; In a resting period, the obese group's serum Free Radical and GSSG content were higher than the normal group's and the normal group's serum GSH content was higher than the obese group's. After 6 weeks of the aerobic program, Free Radical was reduced significantly in both groups(obese group: F=13.87 P=.000, normal group: F=18.60 P=.000) In the obese group, 8 weeks after the program, GSH was increased significantly(F=13.78, P=.000). In the normal group, 6 weeks after the program, GSH was reduced but increased again after 8 weeks(F=6.07 P=.005). Plasma GSSG was significantly increased after 8 weeks of exercise in both groups(obese group: F=19.75 P=.000, normal group: F=22.42 P=.000,) Compared with readings before the aerobic program, the aerobic program made a bigger difference serum GSH in the normal group than in the obese group(t=3.37 p=.003). As this result shows, it is known that the regular aerobic exercise improves cardiopulmonary function, body composition, serum lipid effectively and through the serum Free Radical reduction and antioxidant system activation, oxidant stress was suppressed. This effect was higher in the obese group than in the normal one. At least 6weeks exercise period need for improvement of body composition, cardiopulmonary function and activation of antioxidant system. This result suggest that improvement of serum lipid profile was needed longer than 8weeks exercise period.

In this experiment, the effects of cage density (CD) and probiotic supplementation (PS) on laying performance, metabolic profile, and egg quality in peak-producing hens were evaluated. After blocking according to the cage location, Lohman layers (n = 180, 46 wks of age) were allocated randomly to two levels of CD (540 vs. 360 $cm^2$/hen) and three levels of PS (0, 0.15, and 0.30%). Probiotic contained Enterococcus faecium culture (10${\times}$10$^9$ cfu/g). Egg production (EP) and feed consumption (FC) were measured daily; egg weight (EW) was measured bi-weekly; BW was measured before and after the experiment; and blood samples were obtained at the end of the experiment. The data were analyzed using two-way ANOVA. Increasing CD decreased FC (125.0 vs. 120.8 g/d, p<0.0001) and FCR (1.93 vs. 1.87, p<0.0001) and did not alter EP, EW, and BW. Increasing level of PS linearly decreased FC (p<0.02) and FCR (p<0.006). Averages were 123.9, 123.2, and 121.6 g/d for FC and 1.91, 1.92, and 1.86 for FCR in hens supplemented with 0, 0.15, and 0.30% probiotic, respectively. Hens placed in high-density cages had greater serum corticosterone concentration than hens placed in normal-density cages (12.8 vs. 11.3 $\mu$g/dL, p<0.04); CD did not affect concentrations of other metabolites. Increasing level of PS linearly increased serum glucose, albumin, and creatine concentrations and quadratically increased total protein, globulin, Ca, and P concentrations. Average concentrations (mg/dL) were 260, 297, and 305 for glucose; 6.28, 8.09, and 7.58 for total protein; 1.98, 2.48, and 2.38 for albumin; 4.30, 5.62, and 5.19 for globulin; 0.40, 0.52, and 0.54 for creatine; 16.0, 16.5, and 16.3 for Ca; and 6.27, 8.14, and 7.17 for P in hens supplemented with 0, 0.15, and 0.30% probiotic, respectively. There was no effect of CD on egg quality. Increasing level of PS linearly improved yolk color (YC) and quadratically increased albumen index (AI) and Haugh unit (HU). The mean values were 9.67, 9.75, and 10.58 for YC; 8.94, 6.93, and 8.72% for AI; and 85.6, 74.9, and 82.9 for HU for hens supplemented with 0, 0.15, and 0.30% probiotic, respectively. There was also CD by PS effect on FC, EP, and serum glucose, total protein, albumin, globulin, creatine, Ca and P concentrations. In conclusion, increased CD partially depressed laying performance and caused stress. Probiotic supplementation improved laying performance and metabolic profile. It also partially alleviated the adverse effects of stress resulting from increased caging density.

Objectives : This study was to analyze characteristics of MMPI profile, personality and defensive mechanism on 32 Hwa-byeng patients. Methods : 32 Hwa-byeng patients and 28 normal control group were administered the MMPI. The characteristics of MMPI profile and the clinical scales of personality and defensive mechanism were analyzed statistically. Results : 1. Half of female Hwa-byeng patients are in their forties, twelve patients are high school graduates, housewives seem to have Hwa-byeng more than workers, and married ones have Hwa-byeng more than singles, divorcees or separated one 2. 60.6% patients are getting stressed from their husbands(the specific reasons are infidelity(55%), incapability(25%) and violence(20%)). And the rest are from in-law(28.8%), children(6.4%) and their own parents(3.2%). 3. MMPI profile of Hwa-byeng patients appeared as a type of 3-1 elevated by the scale of 3(Hy) and 1 (Hs). And Hwa-byeng patients appeared significantly high in the rest of scales except L, K, Mf and Ma scales comparing to control group. 4. Hwa-byeng patients were classified into 3 groups. First group is "V" type which is high in K scale and low in 3 (Hy), 4(Pd), 6(Pa). Second group is "V" type which is high in K scale and high in 3(Hy), 4(Pd), 6(Pa). Third group is high in F scale and high in 1(Hs), Z(D), 3(Hy), 4(Pd), 6(Pa), 7(Pt), 8(Sc) and 0(Si). 5. The analysis on MMPI profiles indicates that the thirties are highier in F scale than the fifties, the fifties are highier in Hy scale than the forties, workers are highier in Pd scale than housewives, singles or divorcees are highier in Pa scale than the married. 6. The characteristics of personality in Hwa-byeng patients are as follows. They are significantly lower in HST, NAR and very higher in CPS, PAG, DEP, STY, AVD, SZD comparing to control group. Especially in AVD and SZD scales are appeared the highest.
