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.

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.

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.

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.

The Sertoli-Leydig cell tumor is a gonadal tumor of sex-cord stromal type, similar to that seen in of the various phases of testicular development in the male. This tumor is exceedingly rare, accounting for only 0.1% to 0.5% of all primary ovarian neoplasms. It occurs predominantly in the second and third decades(mean age about 25 years), less than 10% after menopause. We investigated a case of poorly differentiated Sertoli-Leydig cell tumor of right ovary, occured in a 76-year-old woman. Grossly, the tumor measured 2, 100 gm in weight and 25 x 19 x 8 cm in dimensions. The outer surface was smooth and glistening without rupture of the capsule. Cut sections revealed a multilobulated brown solid mass with multiple cystic change. Microscopically, it showed the typical findings o a Sertoli-Leydig cell tumor. The characteristic feature is hemangiopericytoma paftem of sarcomatoid spindle cells. Therefore, we present it with a brief review of the literature.

The radiologic and clinical findings of foreign bodies in the chest of children are well recognized. Foreign bodies in adults are infrequent, however, and the radiologic findings of these unusual circumstances have rarely been described. We classified various thoracic foreign bodies into three types according to their cause: Type I, Aspiration, Type II, Trauma or Accident; Type III, Iatrogenic. This pictorial essay will illustrate the radiologic findings and consequences of thoracic foreign bodies in adults, which have rarely been described in the radiologic literature. The clinical significance of thoracic foreign bodies will be also be discussed.

The author examined the number of AgNORs and PCNA labeling indices by histochemical and immunohistochemical studies in 20 cases of renal cell carcinoma, composed of 5 cases according to the nuclear grades. The results obtained are summarized as follows; 1) Mean number of AgNORs according to the nuclear grades of renal cell carcinoma were 1.38+/-0.40 (mean+/-standard deviation) for Grade I, 2.53+/-0.33 for Grade II, 5.43+/-0.66 for Grade III, and 7.88+/-0.72 for Grade IV. The mean numbers of AgNORs according to the nuclear grades were significantly increased(p=0.0005). 2) PCNA labeling indices (positive nuclear ratio) according to the nuclear grades of renal cell carcinoma were 5.90+/-2.36 for Grade I, 19.30+/-6.71 for Grade II, 45.73+/-8.62 for Grade III, and 61.83+/-6.34 for Grade IV. Also, the PCNA labeling indices according to the nuclear grades were significantly increased(p=0.0008). 3) The mean numbers of AgNORs directly correlated with the PCNA labeling indices (r=0.9861, p<0.001). On the basis of the above results, it was considered that the numbers of AgNORs and PCNA labeling indices as markers of proliferative activity of tumor cells correlate well with the nuclear grades of renal cell carcinoma.
