Oxygen deficiency has been frequent in a clouted space. Wood consumes oxygen and discharges carbon dioxide Instead of photosynthesis in closed space without light, so do some microorganisms on the surface. We experienced a case that a healthy Insect-proofer fell down and died of asphyxia on stair-board at 7 m below the hatch of the cargo-hold shipping wood Analysis of gases in cargo-hold revealed O2; 12.3%, CO; 105 ppm, CH4; 2.7%, and H2S; 1.9% at 1 m below the hatch, and then O2; 6.1%, CO; 220 ppm, CH4; 2.9%, and H2S, 2.3 ppm at 2.5 m below the hatch. Autopsy findings were unremarkable. We justiced the cause of death asphyxia due to oxygen deficiency. As seen in this case, the serious oxygen deficiency was accounted for oxygen consumption by wood and microorganisms.

This study was designed to clarify histologic changes in the experimental rabbit kidney and ureter after unilateral partial or complete ureteral obstruction. A total of 20 adult white rabbits were divided into 4 subgroups in the partial obstruction followed by 2 weeks, the partial obstruction followed by 4 weeks, the complete obstruction followed by 2 weeks, and the complete obstruction followed by 4 weeks. The normal control group was consisted of 5 adult white rabbits. The kidneys and ureters for light microscopy were fixed in 10% neutral formalin, embedded in paraffin and stained with hematoxylin and eosin. Abnormal histologic fingings showed in ipsilateral kidney and ureter of all subgroups(such as dilatation of uriniferous tubule, focal necrosis and desquamation of epithelium, interstitial fibrosis, glomerular congestion, widening of Bowman's space, dilatation of ureter, epithelial cell atrophy or loss, interstitial fibrosis and interstitial inflammation). These findings were most severe in the group of the complete-obstructed ureter for 4 weeks. No significant changes showed in contralateral ureter of all subgroups. The degree of obstruction was severe and period of obstruction was long, the histological changes in ipsilateral side were severe. Despite of changes in ipsilateral side no abnormal findings showed in contralateral side. We suggest that long term experimental investigation of histologic changes in ipsilateral side and compensatory changes in contralateral side have to be studied.

To evaluated the results of long-term follow up of superficial bladder cancer patients who were treated with transurethral resection and intravesical BCG therapy. Between April 1989 and December 1997, 65 patients with superficial bladder cancer were treated with TUR-B(Transurethral resection of bladder tumor) and intravesical BCG instillation, and follow-up was performed for 5 years longer, and the mean follow-up duration was 82 months. Of 65 patients, pathologic stage were Ta in 17 cases and T1 in 48 cases and grade were G Ⅰ in 22 cases, G Ⅱ in 35 cases and G Ⅲ in 8 cases. The tumor recurred in 22(33.8%) at the median of 21.8 months and the tumor progressed in 9(13.8%) at the median of 20.8 months. Most of the recurrences and progression were within 3 year(838 and 77%). Progression is more likely in higher grade(G Ⅱ, G Ⅲ) and higher stage(T1). The complete response rate after first and second courses of BCG therapy were 53% and 73% and the 5 and 10 year disease specific survival rates were 89.5 and 78% respectively. The complete response rate after first and second courses of BCG therapywere 53% and 73%. Most of recurrences and progressions were within 3 years of the BCG therapy, but some cases occured after 5 years. Therefore, close long-term follow up is needed.

Head injury is the most frequent direct cause of death in sports. Furthermore, injury to the head takes an singular importance when we realise the brain is neither capable of regeneration nor, unlike many other body parts and organs, of transplantaion. Every effort must be made to protect the athlete's head as injury can lead to dementia, epilepsy, paralysis and death. There are three distinct types of stress that can be generated by an acceleration force to the head : compressive, tensile and shearing forces. The differential diagnosis with a head injury includes cerebral concussion, intracranial hemorrhage, postconcussion syndrome, second impact syndrome, malignant brain edema. 90 to 95% of all head injuries are cerebral concussions and more than 90% all cerebral concussions fall into mild categories. With a head injury the ABCs of first aid must be followed and then a neurological examination will be followed. In the case of the intracranial hematoma. definite surgical evacuation is indicated and in cases of the closed head injuries and most severe degree of concussion. observation is appropriate, with careful neurological monitoring. Over the last 20 years there has been a dramatic decrease in the most serious head injuries due to multiple factors. There are five areas that can affect a reduction in head injuries. The first two involve rules and coaching technique changes. The other three areas involve improvements in conditioning (especially of the neck), equipment, and finally medical supervision. The reduction in incidence and severity of athletic head injury gas been the results of changes and improvements instituted following constant study and research. And also, for the reduction in incidence of athletic head injury every effort or team physician, athletic trainer, physical trainer and team coaches should be necessary.

As unbanization and population have been increasing, cometerys have caused a lot of social problems. In order to improve these, a cemetery park with various functions like cemetery and park should be made. A cemetery park can provide neighboring people as well as cemetery users with spaces for relaxation and graves. Therefore the purpose of this study is to suggest basic directions for efficient policy which can change people's way of thinking about a propitious grave site and form new land culture. The conclusions are : First, in the aspect of system, laws related to burial and cemetery-grave size, and structures-should be changed in pace with people's consiousness and the rationalization of land. Second, in the aspect of administration, roads to cemetery parks, landscape and facilities should be prepared. And the plan should be made which neglected or unknown graves can be checked to be put in charnel. Besides by analyzing good and bad points of old cemetery, better ones should be made. It should take the department concerned and experts to manage the efficient policy for cemetery. Third, in the aspect of people's consciousness constant publicity activites about the efficient use of land will help to solve a sense of incompatibility caused by using excessive use of cemetery. Fourth, as this research shows, enough greenbelt and parking areas must be prepared with landscape, facilities and management improved.

We have used molecular biology technique to label the side chains and backbone of HBV preS1(1-56) with stable isotope (??) during E. coli over-expression and purified the protein to near homogeneity. The expression level of ?? labelled preS1(1-56) seems to be ∼15% of the total protein. to characterize the secondary structure of the labelled protein, circular dichroism was used. In different buffer conditions including pH 3.3 and pH 7.4 the protein seems to be devoid of any stable secondary structure probably suggesting that the N-terminal portion (preS1(1-56)) of HBV preS1 might be unstructured before binding to its target cells.

To examine the photosensitizing properties of 9-methylanthracene and 9-phenyl-anthracene, the concentration change of DPBF was determined during the irradiation with the light of 366nm in 95% MeOH, SDS and CTAB aqueous micellar solution at various pH. The concentration decreasing of DPBF by photosensitization was fast at low pH and especially was found to be very sensitive to the changes of pH in the range 4∼6. At high pH, the produced singlet oxygen seemed to be decayed by the reaction of OH. And it was found that the concentration of DPBF was decreased more fast in 95% MeOH solution than in aqueous micellar solution. Such results are believed that environment of the aqueous micellar solutions is more polar than that of 95% MeOH. It was also found that the 9-PA was more effective photosensitized than 9-MA, and the abilities of 9-PA and 9-MA to photosensitize oxidation reaction were found to be greater in SDS aqueous micellar solution than in CTAB aqueous media.

The concentrations of volatile organic compounds (VOCs) in the ambient air were measured at three sites (Samil-dong, SRO and EFMC) in Yeosu industrial complex during September 2000 to August 2001. Air samples were collected for 24 hours in Silicocan canister (6ℓ) with constant flow samplers every 6 days and analyzed using a cryogenic preconcentration system and a GC/MS. At each site, we identified 35 species known as on both the carcinogenic and mutagenicity by the EPA US (TO-14 manual). No relationship was found between VOCs concentration at three sampling points. Furthermore, the result shows that there appears to be a variety distribution of the concentration. BTX, vinyl chloride and high concentrations of I, 2-dichloroethane were observed at the sampling sites. Especially, high concentration of toxic VOCs, such as vinyl chloride, chloroform, I, 2-dichloroethane and benzene were shown at environmental facilities management cooperation (EMFC) site. They seem to be emitted from the facility of wastewater treatment in Yeosu industrial complex. It was difficult to tell the seasonal variation of total VOCs concentration. Nevertheless, the concentration in winter was typically higher than in summer. The concentrations of toxic VOCs contents in Yeosu industrial complex were generally lower than those in Ulsan complex, although those were similar or less than in Seoul and Daegu. Whereas, toluene and styrene emitted from Yeosu industrial complex were higher than those of Edmonton industrial complex in Canada. Especially, toluene was third times higher than those observed from Texas, USA.
