Background : The part to be very important that we make the physical development rightly at elementary school student days. Objective : This study investigated the relation of a physical health status which itself recognizes and an exercise performance situation out for an elementary school students. Methods : This cross-sectional study examined health and exercise performance status of 1,032 elementary school children. To examine children's a physical injury experience and injury occurrence characteristic and a personal computer utility condition, a body alignment status of the student which parents recognize and the relation of a fatigue and concentration level was an investigation with other factors. Results: An average age of the children was the 10.95 yr and an average weight was the 39.02 kg and an average height was the 145.17cm. The student to be experiencing currently an pain occurrence was 192(19.07%). It was most high to the grade 6(23.33%) compared with different grade(p<.01). Physical pain occurrence rate did not exist by gender(p>.05). There is most an pain occurrence region the ankle(38.0%). They had a 27.19% an physical injury experience of the students. A injury rate was revealed that were high as were the high grade(grade 6, 36.72%)(p<.01). A reason of the injury rate was high in a collision at the body(19.84%), falling down(18.68%) sequence at a traffic accident(22.96%)(p<.05). There were the significant relation to the school year the reason of the injury (p<.05). Currently there was the student to be taking special exercises a 57.97%. This that they have the relation with exercise with physical pain students to recognize 23.8%. The significant relation did not exist in the physical exercise execution and pain occurrence on the body(p>.05).

The hand is a part of the body which has various functions and a sophisticated structures bone, Joint, tendon, ligament and logical nerve organ are aggregated densely in the hand of anatomy its functions are delicate. The hand's functions are very important for doing ADL and a worker's As the hand is structure which is used often and commonly it is a site that can be easily damaged by a accident on work. This study was investigated and analyzed by the results from 238 workers who had hand injury and physical therapy from January, 1997 to June, 1998 at Shin-Pung, Jang-Lim industrial complex which is located in Pusan. 1. A hand injury most frequertly happened in worker in their 30's and 20's(66 case, 28%), second was 57 case(24%) their 40's. 2. Among workers suffering from injury, who had one or less than 2 years on the job, a injury most frequently occurred. 3. Scale of workers, A injury most frequently happend in a place where had workers from 10 to 50. 99 workers from that place were 42% of total. 4. Month of occurrence rate in March were the highest compared to other months 40 injury workers in march were 17% of the total. Second was July, and the least was April that injury appeared with 10 workers. (4.2% of the total) 1. Frocture was the most common lesion 82 workers had that lesion(34%) soft tissue rupture was 71 workers who were 30% of total in type of lesion. 2. Of the site of lesion multiple case was the most common in which 57 workers had that lesion it were 24% of the total. The next was the index finger site in which 44 workers were 19% of the total. The index finger was the most common mono-site that can be lesion 36 workers were the middle finger lesion workers who were 15% of the total. Of the joint lesion, PIP was the most in which 76 workers were 44% and in MC 27 workers were 15% of the total. 3. Interval of physical therapy 79 workers from one month to 2 months, was 33% of the total and 174 workers who had therapy below 3 months were 71% 4. Post injury of disablity of the site, phalangeous disability was the most in which 148 workers had that injury and they were 62% of the total of the grade of disability 110 workers who were 46% of the total state from less than 25% disability in hand-function and 59 patients who were 25% had no disability.

The author used rabbits in order to examine the effect of Ga-As low power generating semiconductor laser on artificially produced injuries of experimental animals. Artificially produced injuries include surgical wound of 3mm length, 2mm depth in size on ventral skin surface of rabbit and buccal mucosa, and electrical injury formed on opposite side of skin and buccal mucosa by electrical cauterization of same length and depth, and chemical injury formed by FC(Formocresol) solution applied on the anterior dorsal part of tongue. And then, on the experimental group, Ga-As laser was irradiated beginning on the day after the wound formation and continued to irradiate every each other day for five minutes. After1, 3, 6, 9, 13th day, certain number of animals of control and experimental group were sacrified, and wound site tissue was excised to make samples and was observed under light microscope. The following is the conclusions after comparing the healing procedure of experimental and control group. The following results were obtained : 1. Inflammation was decreased more rapidly in the experimental group than the control group. 2. In the surgical, the electrical and the chemical injuries in the oral mucosa, re-epithelialization was completed more rapidly in the experimental group than the control group. In the electrical injury on the skin, re-epithelialization was completed about 6 days after wound formation on both groups. 3. In the electrical and the surgical injuries on the oral mucosa, granulation tissue formation started at 3 days after injury on both groups, but in the chemical injury, it was completed about 3 days faster in the control group than the experimental group. In the surgical wound on the skin, it was completed about 9 days after injury, but faster in the experimental group. In the electrical injury on the skin, it was faster in the control group than the experimental group. 4. In the electrical and the surgical injuries on the oral mucosa, fibrosis was started at 6~9 days after injury on both groups, but regeneration of connective tissue in the experimental group was observed much more than the control group. 5. When comparing the effect of wound healing on skin and oral mucosa of control and experimental group, granulation tissue formation and re-epithelialization in the oral mucosa was more vigorous. In conclusion, the difference of timing and the sequence of wound healing process(inflammation, re-epithelialization, granulation tissue formation, fibrosis) following Laser irradiation between control and experimental group was not observed, but the healing tissue was observed much more in the Laser irradiated group.

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and potentially fatal condition characterized by skin rash, fever, eosinophilia, and multiorgan involvement. Various drugs may be associated with this syndrome including carbamazepine, allopurinol, and sulfasalazine. Renal involvement in DRESS syndrome most commonly presents as acute kidney injury due to interstitial nephritis. An 11-year-old boy was referred to the Children's Hospital of Pusan National University because of persistent fever, rash, abdominal distension, generalized edema, lymphadenopathy, and eosinophilia. He previously received vancomycin and ceftriaxone for 10 days at another hospital. He developed acute kidney injury with nephrotic range proteinuria and hypocomplementemia. A subsequent renal biopsy indicated the presence of acute tubular necrosis (ATN) and late exudative phase of postinfectious glomerulonephritis (PIGN). Systemic symptoms and renal function improved with corticosteroid therapy after the discontinuation of vancomycin. Here, we describe a biopsy-proven case of severe ATN that manifested as a part of vancomycin-induced DRESS syndrome with coincident PIGN. It is important for clinicians to be aware of this syndrome due to its severity and potentially fatal nature.

Stimulated alveolar macrophages and neutrophils produce nitric oxide, a free radical by an inducible nitric oxide synthase(iNOS), which reacts with superoxide anion to form peroxynitrite, a more highly reactive toxic species. The objectives of the present study were to evaluate acute inflammatory lung injury and to determine iNOS mRNA induction and nitric oxide production by rat broncho-alveolar lavage cells following intratracheal treatment of silica. After 4 h exposure to silica, differential counts of broncho-alveolar lavage cells and lactate dehydrogenase(LDH) activity as well as total protein in the broncho-alveolar lavage fluid were determined. Broncho-alveolar lavage cells were also assayed for iNOS mRNA and the productions of nitrite and nitrate measured in the cells cultured. Differential analysis of broncho-alveolar lavage cells showed that the number of alveolar macrophages slightly decreased following silica treatment; however, red blood cells, lymphocytes, and neutrophils significantly were increased by 9-, 14-, and 119-fold following silica treatment, respectively, compared with the saline control. It was also found significant increases in the LDH activity and total protein in the lavage fluid obtained from silica-treated rats, indicating silica-induced acute lung injury. Northern blot analysis demonstrated that the steady state levels of iNOS mRNA in broncho-alveolar lavage cells were increased following silica treatment. The productions of nitrite and nitrate in the cultured cells were significantly increased by 2-fold following silica treatment, respectively, which were attenuated by the NOS inhibitor $N{\omega}-nitro-L-arginine-methyl$ ester(L-NAME) and partially reversed by L-arginine. These findings suggest that nitric oxide production in alveolar macrophages and recruited neutrophils is increased in response to silica. Nitric oxide may contribute in part to acute inflammatory lung injury.
