BACKGROUND: Previous studies have suggested that regular exercise may increase bone mineral density. However, the effects on bone mineral density are different depending on the types of exercises and recent studies on the effects of different exercises on bone mineral density are insufficient. This study was conducted to assess the effects of 2 different exercises(Judo, Taekwondo) and physical fitness(back muscle strength, grip strength, broad jump, vertical jump, flexibility, sit ups) on regional BMD. METHODS: Subjects were healthy adults female volunteers aged 19 to 22 years and consisted of eight Judo athletes, twelve Taekwondo athletes, and eight nonathletic controls. We measured their bone mineral density of lumbar spine, femoral neck, femoral greater trochanter, Wards triangle, femoral shaft and distal radius using dual energy X ray absorptiometry and assessed their physical fitness. We investigated the mean differences of regional bone mineral density between the groups and the relationships between physical fitness and regional bone mineral density. RESULTS: ANCOVA revealed that there were significant differences in the regional bone mineral density between the groups. The Judo athletes group had significantly higher bone density of greater trochanter, femoral shaft, distal radius, femoral neck and lumbar spine than the control group and had significantly higher bone density of greater trochanter, femoral shaft and distal radius.than the Taekwondo atheletes group. There were no significant differences of bone density in all the regions between the Taekwondo atheletes and the control groups. Partial correlation coefficients between the back muscle strength and the bone density of Wards triangle, greater trochanter, distal radius, femoral neck, femoral shaft, and lumbar were 0.581, 0.570, 0.526, 0.502, 0.424, and 0.418, Respectively (P<0.05). Correlation coefficients between the broad jump and the bone density of femoral neck, greater trochanter, and femoral shaft were 0.577, 0.539, and 0.457, respectively(P<0.05). Correlations of the grip strength, flexibility, sit ups and vertical jump with bone density of all regions were not high(r< or=0.5). CONCLUSIONS: Different types of exercises showed different effects of bone density. The back muscle strength among the physical fitness factors was considered to be the most important predictor of bone density. In the future, further studies are necessary for the effects of other exercises on bone density.

The third complementarity determining region (CDR3) of the immunoglobulin (Ig) kappa () chain is known to be located at the center of antigen binding groove and critical for antibody specificity. Ig chain has been characterized by limited junctional diversity due to the absence of N-region addition resulting in relative conservation of CDR3 lengths with 9 or 10 amino acids. CDR3 region of 11 amino acids is only possible with N-region addition. Recently, x transcripts with 11 amino acids CDR3 was found to be expressed in normal individuals, and in autoimrnune disease such as rheumatoid arthritis, the fraction of 11 amino acids CDR3 of humkv325-derived chains was overexpressed compared to conventional adult peripheral B cells. However, the significance of this bias is difficult to interpret without a clear understanding of normal repertoire of CDR3 length during development. The purpose of this study is to determine whether developmental regulation of CDR3 amino acids codon lengths exists in chains expressed in the fetal liver, cord blood, and adult peripheral blood lymphocytes (PBL). Lymphocytes were seperated from fetal liver, cord blood and adult PBL and cDNA was generated from extracted mRNA. PCR-based CDR3 finger- printing assay was performed with VI-IV family specific primers. CDR3 length diversity of Ig x chain increases as the development proceeds. The length diversity most frequently occured in Vlll family derived transcripts including 11 amino acids CDR3. transcripts with 11 amino acids CDR3 were consitently expressed in both fetal and adult Ig repertoire. These results support the hypothesis that v chain CDR3 length is developmentally regulated and implicates the diversity of antigen-antibody specificity generation.

In the surgery of central area, identifying the motor cortex in front of central sulcus is imperative to prevent loss of motor function. Twenty five patients with tumors or intractable epilepsy near the central sulcus were operated on at the Department of Neurosurgery of Chonbuk National University Hospital, from September. 1991 to December 1993. An estimated localization of lesions was performed with Callosal Grid System, which is a methodolgy made available by the development of high quality of magnetic resonance imaging, digital subtraction angiography and high resolution computerized tomography. This system allowed us to be oriented to the motor cortex as well as permitted assessment of the extent of resection. This was further delineated by direct electrical stimulation, which confirmed the functional motor cortex and made it possible to maximized the tumor resection near and in the motor cortex. The combination of direct cortical stimulation(functional mapping) and the use of the Callosal Grid System(anatomical mapping) allowed us to identify the spatial relationship between them as well as to maximize the tumor resection in most cases without injury to the central area, so that the better outcome is guaranted.

BACKGROUND: It is widely acepted that muscle strength and bone mineral density have a significant positive correlation and most previous literature focus on the association between specific muscle groups and adjacent bones. This study examined the association of grip strength with bone density at distant sites, such as spine and femur area in peri- and postmenopausal women. METHODS: The study subjects were 30 perimenopausal and 108 post menopausal women aged 40 years older. Bone mineral density was measured in both the dominant and nondominant hands using a dynamometer. Other data was gathered from the questionnaire. RESULTS: Significant negative correlations were noted between spinal and femoral bone mineral density and age and post menopausal duration, and significant positive correlations were fiund between spinal and femoral bone mineral density and body wweight, height, body mass index and both grip strength. Those who exercised had significantly higher spinal bone mineral density than those who did not and smokers had significantly lower spinal bone density than nonsmokers. There was no significant difference in bone mineral density by estrogen and calcium use. The multiple regression analysis examined the associatrion of grip strength in the dominant hand to a bone mineral density after adjustment for the confounding covariates. CONCLUSION: Weak grip strength in the dominant hand is a marker for lower bone mineral density in peri- and postmenopausal women. Grip strength can be a useful index of osteoporosis.

The major presenting manifestations of systemic lupus erythematosus (SLE) in Korea are known to be cutaneous manifestations, arthritis, nephritis, and fever. The ascites due to peritoneal involvement in SLE is quite common. However, it is unusual for massive ascites to be major presenting manifestations of SLE. In this report, we describe a case of SLE patient whose disease manifested as intractable ascites. This illustrates an unusual presentation and natural history of a complex autoimmune disease.
