The purpose of this study was to investigate that there was any differences of uptake ratio of Tc99-m-MDP during the healing process related to fracture level in tibia. Thirty mature rabbits were devided into three groups and each group consisted of ten rabbits. The osteotomy was performed at the proximal third of tibia in group I, at the middle third in group II and at the distal third in group III, respectively. After fracture was reduced, the fractured tibia was fixed with K-wire and immobilized with long leg cast. Serial Tc-99m-MDP scintigraphy with pixel counting method was performed in thirty cases of tibial shaft fracture from one day to eight weeks after fracture. The results obtained were as follows: l. In group I, the mean uptake ratio of Tc-99m-MDP at fracture site was 1.40±0.45 at two days after fracture, 3.34±1.21 at two weeks and increased rapidly to a maximal value of 7.51%1.01 at three weeks and decreased thereafter to 4.530.83 at eight weeks. 2. In group II, the mean uptake ratio was 1.10±0.10 at three days, 3.931.±10 at three weeks and increased rapidly to a maximal value of 7.37±2.21 at four weeks and decreased thereafter to 4.54±0.96 at eight weeks. 3. In group III, the mean uptake ratio was 1.13 ± 0.11 at three days, 3.95±0.93 at three weeks and increased rapidly to a maximal value of 7.43±1.72 at four weeks and decreased thereafter to 4.69±0.93 at eight weeks. These experiments suggest that the changes of Tc-99m-MDP scintigraphy in the proximal third fractures of tibia was earlier than middle or distal third fractures and there was no differences between middle and distal third fractures of the tibia.

PURPOSE: This study was done to provide data that would contribute to effective task performance in clinical nursing and development of nursing professional by understanding job stress, job satisfaction and organizational commitment according to Life Organization (LIFO) behavior types of novice nurses. METHODS: This study was a cross-sectional survey and the participants were 313 novice nurses who worked in one university hospital located in the city of Gwangju. Data were collected through the structured questionnaires that included general characteristics, job stress, job satisfaction, and organizational commitment scales. Collected data were analyzed using descriptive statistics, and ANOVA with SPSS/WIN 19.0. RESULTS: Regarding job stress according to LIFO behavior types of novice nurses, there were statistically significant differences between the favorable situation and the unfavorable situation. There were also statistically significant differences regarding the organizational commitment according to LIFO behavior types. CONCLUSION: The results indicate a difference in behavior patterns of novice nurses that suggest a need for education in order to reduce stress from the job and enhance organizational commitment by developing each nurse's preferred pattern and compensating for unfavorable patterns, as well. There also needs to be nursing resources that take into consideration behavior patterns of novice nurses.

Interlocking medullary nails have been widely used in the treatment of long bone fractures especially in tibia and femur. But with increasing use of nails, many preoperative, intra-operative and post-operative complications have been reported. We have experienced 3 cases of very rare complication, fracture of tibia shaft which occurred during removal of interlocking medullary nail after complete healing of original tibial fracture. We report these rare complications with literature review.

In orthopedic practice, patients sometimes ask certain kinds of medical documents certifying their disability grading. But many orthopedic surgeons are not accustomed to issue such medical certificates. So we want to review the way of evaluation and grading of disabilities for such different kinds of medical certificates(for examples: disability grading certificate for use in traffic accident, industrial accident, liability of national compensation, private insurance, the handicapped, military service and others) and compare the differences between them.

We report a case of Buerger's disease manifested by a scrotal mass, in view of its rarity. A tender bean sized mass was palpated in the left scrotum of a 34 year-old male heavy smoker, who had a history of right pain two years ago which subsided spontaneously. The left testis with the paratesticular tissue was excised. Vessels of the spermatic cord and epididymis showed microscopic changes of Buerger's disease. The involved arteries and veins revealed a predominantly subacute pattern with granulomatous inflammation and Langhans' type giant cells within the thrombi.

Vibrio damsela is a halophilic bacterium that has been reported to cause skin ulcers and death in damselfish (Chromis punctipinnis) as well as wound and soft-tissue infections in human. Most of the previously reported cases in humans haute involved wound infections associated with exposure to seawater or handling fish. We experienced a case of primary septicemia due to V. damsela after eating raw fists in a healthy 66-year-old woman who had neither wounds nor history of exposure to sea- water. She presented fever and diarrhea followed by rapidly pregressive bullae and painful edema on left band and forearm. The patient was Improved by intensive surgical debrldement of necrotic tissue and antibiotic therapy.

Hepatitis B virus (HBV) currently infects more than 400 million people worldwide and they are at risk of developing chronic liver disease, cirrhosis and hepatocellular carcinoma. The immune response to HBV- encoded antigens is responsible both for viral clearance and for disease pathogenesis during HBV infection. While the humoral antibody response to viral envelope antigens contributes to the clearance of circulating virus particles, the cellular immune responses to the envelope, nucleocapsid, and polymerase antigens were known to eliminate virus in infected hepatocytes through cytolytic as well as noncytolytic mechanisms. Liver injury could be initiated by an immune response against HBV, but mainly resulted from HBV non-specific lymphocytes and macrophages. There are growing evidences that T helper 1 memory T cells play a predominant role in suppressing viral replication mainly by IFN-gamma through noncytolytic antiviral mechanism. Elucidation of the immunological and virological basis for HBV infection may yield effective immunotherapeutic and antiviral strategies to terminate chronic HBV infection.
