To estimate the prevalence and trend of obesity in primary school-age children, obesity survey was performend in children aged 6 to 12 years(5,226 boys and 5,048 girls)in Kwangju in 1991. Obesity was defined as overweight if more than 20 per cent above the median weight for height and age(relative weight>120%). The following results were obtained: 1) The prevalence of obesity that exceeded the weight centiles at each height by more than 97th percentile was 8.78. Boys (9.70%)was not significantly higher than in girls(7.82%)(p>0.05). 2) The prevalence of obesity that exceeded the standard weight for height by more than 20% was 8.82%. Among them, 5.45% were mild obesity and 2.93% were moderate obesity and 0.44% were severe obesity. The prevalence rate of obesity was no significant differences by sex(p>0.05). 3) Regionally, the prevalence of obesity was a lower rate in Kwangiu in 1991 (8.82%)than that in Seoul in 1989(11.68%).

The objectives of this study were to examine the changes of birth weight and relationship of birth weight with maternal age and parity. The study population included 13,634 single live births out of 14,346 births delivered at a general hospital in Busan between January 1, 1977 and December 31, 1986. Data were obtained from the delivery record. In 1979 the mean birth weight of male was 3,074 gm and that of female to 2,985 gm. In 1986 birth weight of male was increased to 3,266 gm and that of female to 3,210 gm. Low birth weight (< or = 2,500 gm) incidence rate was 7.2% in 1977 and it was increased gradually to 10.4% in 1980 but decreased thereafter to 6.5% in 1986. Incidence rate of overweight infant (4,001 gm < or =) was 3.9% for 10 years and it ranged from 2.9% to 4.6% but no particular changing pattern was observed. The percentage of mothers who had history of induced abortion was decreased from 51.6% in 1979 to 45.1% in 1986. Also, stillbirth rate was decreased from 2.6% in 1977 to 1.5% in 1986. The proportion of the first and second births was increased from 85.4% in 1977 to 96.0% in 1986 and the proportion of mothers of 25-34 years increased from 72.1% in 1977 to 84.7% in 1986. The incidence rates of low birth weight and over weight infant are lower in the first and second births of 25-34 years old mothers than other parities and age groups. In creased mean birth weight and decreased low birth weight incidence rate indicate that the health status of newborn infants has been improved and substantial portion of these changes can be attributed to increase in family planning practice rate and delayed marriage. There is no evidence, however, for increasing incidence rate of overweight infant.

Treponema strain PFB4G is a novel oral spirochete and one of the most frequently detected organisms in subgingival plaque samples from rapidly progressive periodontitis and adult periodontitis patients. In this study, a genomic library of Treponema strain PFB4G was constructed in lambdaZAP expression vector. One positive clone that carried a 2.6-kb fragment was identified by screening with chicken Ig Y (immunoglobulin yolk) antibody raised against whole bacterial sonicates. Nucleotide sequencing of the subclones revealed an open reading frame (ORF) lacking the 5'-end. This region was obtained by PCR amplification using a degenerative and a specific primer. A complete open reading frame of 1,770 bp was identified and the deduced polypeptide consisted of 590 amino acids with a molecular mass of 65 kDa. The polypeptide, designated as OmpTL, had a typical prokaryotic signal sequence (19 amino acids) with a potential cleavage site for signal peptidase I and showed a significant level of homology with the outer membrane proteins of other oral treponemes, especially with that of Treponema maltophilum. The isolation of the gene encoding an outer membrane protein may allow the study of their roles in future, possibly as adhesion, pore forming or induction of proinflammatory cytokine synthesis.

The area overlying the ischium is the most frequent site for the development and recurrence of pressure sores in the paraplegic patient. This report describes a newly-designed inferior gluteus maximus myocutaneous island flap that is useful for the repair of ischial pressure sores in paraplegic patients. Sacral sore develops a wide and flat ulcer crater. However, ischial sore seems to develop large and deep bursa with relatively small openings. We have used a newly-designed gluteus maximus myocutaneous island flap according to the specific characteristics of ischial sore. The flap is designed in the fashion of a small skin island with a large muscle flap. This flap with its abundant and constant blood supply had proved very reliable in the surgical management of ischial pressure sore. There is also the possible advantage of cushioning with the bulk of muscle for greater long-term durability. Incision could be extended for a complete bursetomy and partial ischiectomy. The reliability, versatility and low morbidity of the inferior gluteus maximus island flap has been demonstrated by its use in our consecutive series of 7 patients with 8 ischial pressure sores. We conclude that this newly-designed inferior gluteus maximus myocutaneous island flap can be applied in deep, infected ischial sore according to the specific characteristics of ischial sore, and it is a very useful method in comparison to other flaps.

Additional two cases of Klinefelter's syndrome with a literatural review was presented Two cases were revealed characteristics of Klinefelter's syndrome such as small testes, hyalinization of seminiferous tubules, azoospermia, increased FSH, normal 17-ketogteroid and positive sex chromatin. One case was associated with left inguinal crytorchidism.

Thirty-nine healthy pigs (28-32 days old) were purchased from a commercial swine farm and housed at swine pens of the College. The animals were vaccinated intramuscularly (1 ml) with an attenuated live hog cholera virus (HCV, LOM strain) and then boostered at 5 weeks after the first vaccination. The animals were divided into 4 experimental groups: 0.05% (w/w) PowerFeel-supplemented diet (T-1, n = 10); 3% (w/w) SuperFeed-supplemented diet (T-2, n = 10); diluted PowerFeel solution (1 : 500, v/v) as drinking water (T-3, n=9); control (n=10). PowerFeel is an original form of ionized alkali mineral complex (IAMC) and SuperFeed is a commercial product of IAMC. The subpopulation of lymphocyte in blood was assayed by a flow cytometry and HCV-specific antibody was determined by an indirect immunofluorescence assay. In IMAC-treated groups, the proportions of subpopulation expressing MHC-class II, CD2+, CD4+, CD8+, and surface IgM+ B lymphocytes were significantly decreased at 5-weeks after the first vaccination. Significant decreases were also observed in the proportions of MHC-class II, CD2+ and CD8+ lymphocyte at 3-weeks after the booster injection. The humoral immune responses in T-1 and T-2 groups were greater than those in T-3 or control group. These results suggest that IAMC-supplemented diets may have an HCV-specific immunostimulatory effect in pigs.
