Vaccinia virus is the prototype orthopoxvirus that has been used as a vaccine strain for small pox. This virus has been used to express a variety of cellular and viral genes in mammalian cells at high levels. Interleukin-4 (IL-4) has been found to stimulate the proliferation of T cells and enhance the cytolytic activity of cytotoxic T lymphocytes. To test the immunotherapeutic potential of IL-4 delivered in vivo by poxvirus, a recombinant vaccinia virus expressing the murine IL-4 gene (RVVmIL-4) was constructed. A high level of IL-4 production was confirmed by infecting HeLa cells and measuring IL-4 in cell culture supernatant by ELISA. As a tumor model, two cell lines were used: the murine T leukemic line P388 and the murine breast cancer line TS/A. CDF1 mice were intraperitoneally inoculated with 1 x 105 cells of P388. Mice were injected at the same site with 5 x 105 PFU of recombinant vaccinia virus; first, 3 days after the injection of tumor cells and thereafter once every week for 3 weeks. Intraperitoneal injections of RVVmIL-4 significantly prolonged the survival time of mice inoculated with tumor cells. All mice injected with RVVmIL-4 remained alive for 30 days after the postinoculation of tumor cells, while 100% and 70% of the animals injected with saline or wild type vaccinia virus died, respectively. In another tumor model using TS/A, tumor was established by subcutaneously inoculating 2 x 105 tumor cells to BALB/c mice. After tumor formation was confirmed on day 4 in all mice, 5 x 106 PFU of RVVmIL-4 was inoculated subcutaneously three times, once every week for 3 weeks. The TS/A tumor was eradicated in two of the nine mice. Seven of the nine mice treated with RVVmIL-4 developed a tumor, but tumor growth was significantly delayed compared to those treated with saline or wild type vaccinia virus. These results indicate that recombinant vaccinia viruses may be used as a convenient tool for delivering immunomodulator genes to a variety of tumors.

PURPOSE: The purpose of this study is to identify the influence of job stress and empowerment on nursing performance of clinical nurses working in small and medium hospital. METHODS: The empirical data were collected from a self-administered survey using a structured questionnaire with 404 nurses working in 4 medium-sized hospitals (less than 300 beds), located in I-city. The data were analyzed using stepwise multiple regression with the SPSS/WIN 17.0 program. RESULTS: There were significant differences in nursing performance depending on general characteristics (age, marital status, religion, shift work, education level, position, clinical experience, department, and monthly salary). Empowerment correlated with nursing performance. Factors influencing on nursing performance were empowerment, clinical experience, job stress, and marital status with R2 value of 36.3%. The most influencing factor was empowerment (beta=.47), followed by clinical experience (beta=.24), job stress (beta=.20), and marriage (beta=.12). CONCLUSION: It is needed to implement specific empowerment strategy, control job stress, and reward experienced and married nurses working in medium-sized hospital for improving nursing task performance.

Twelve patients with inflammatory bowel disease had been operated at the department of surgery, Chonnam University Hospital during the period from March 1988 to February 1997. In this study, we report on the operative cases regarding age, sex, symptoms, duration of disease, location of disease, preoperative diagnosis, operative indication, frequency of operation, histopathologic findings and follow up. The results were as follows: 1) The male to female ratio in ulcerative colitis was 1 : 1, and the mean age was 54.5 years. In Crohn's disease, male to female ratio was 2.3 : 1 and the mean age was 42.1 years. 2) The mean duration of symptoms in ulcerative colitis was 39 months and in Crohn's disease was 13.9 months. The common symptoms in ulcerative colitis were abdominal pain, bloody diarrhea, indigestion, weight loss and in Crohn's disease abdominal pain, palpable mass, weight loss, indigestion. Extraintestinal symptoms in Crohn's disease were cholelithiasis like symptom, anal fistula, anal fissure. 3) The involvement site in ulcerative colitis was large bowel only, but in Crohn's disease small bowel (50%), large bowel (20%), small and large bowel (30%) were involved. 4) Preoperative diagnosis in ulcerative colitis was accurate, but in Crohn's disease accurate diagnosis was made only in 20% and the other cases were operated under the impression of different diseases or conditions (intestinal tuberculosis (50%), bowel perforation (20%), mechanical ileus (10%)). 5) The indication of surgery in ulcerative colitis was intractability to medical treatment, on the other hand, in Crohn's disease most operative cases were made under the emergentconditions (bowel perforation, bowel obstruction, enterocutaneous fistula, abdominal mass). The frequency of operation in ulcerative colitis were two times in one case, three times in one cases. In Crohn's disease half of cases experienced two or three times of surgery. The method of operation in ulcerative colitis was total proctocolectomy with J-pouch ileoanal anastomosis. In Crohn's disease resection of diseased bowel segment was performed.

Colorectal carcinoma in patients under 40 years and over 70 years of age is unusual but not rare. The prognosis of these two groups, compared with remainder of patients, is thought to be unfavorable. From Jan. 1981 to Dec. 1997, 541 patients with primary colorectal cancer who were treated by surgical resection were analyzed retrospectively. They were divided into three age groups according to the age at admission, i.e. under 40 years, over 70 years and between 40 and 69 years(control group). Among three age groups, sex ratio, tumor characteristics(size, location , depth of invasion, lymph node metastasis, liver metastasis, peritoneal metastasis, histopathologic classification, stage, DNA ploidy pattern), serum CEA level and survival were compared and analyzed. The results were as follows: 1) In the young patient group(52 cases), female predominence, large tumor size, high proportion of mucinous adenocarcinoma in histopathologic classification, more frequent metastasis to regional lymph node, frequent peritoneal metastasis and high incidence in tumor location at transverse colon were noted(p<0.05). 2) In the elderly group(69 cases), deep invasion of tumor(T4) was noted (p<0.05). In addition, among them, concomittent diseases were presented in 25 patients(36%). They were diabetes(8), cardiac arrhythmia(4), old myocardial infarction(2), liver cirrhosis(5), COPD(3), previous cancer(3). 3) The 5-year survival rates of the young patient group and that of elderly patient group were lower than that of the other(p<0.01). 4) There was no significant differences in liver metastasis, tumor stage, DNA ploidy pattern, serum CEA level among three age groups.

Many authors reported the etiology of hypoplasia of the nasomaxillary complex as trauma, infection, underdevelopment. To correct these deformities, Le Fort II Osteotomy and its modification has been popularly applied. This method enabled total advancement of nasomaxillary complexes and acquirememt of midfacial esthetics. But it has some limitations such as various occlusal deviation or lateral shifting of nasomaxillary complex in case of nasomaxillary retrusion. We grouped these patients as follows : 1. Nasomaxillary retrusion without shifting of nasomaxillary complex (1) Anteroposterior deviation of occlusal plane (2) Lateral deviation of occlusal plane(including canting) (3) Supero-inferior deviation of occlusal plane (4) Combined disturbance of occlusal plane without shifting of nasamaxillary complex 2. Lateral shifting of nasomaxillary complex with or without deviation of occlusal plane We performed Le Fort II and I combined osteotomy on eleven cases of midfacial deformity from June 1994 to July 1997 and in most of the cases, followed up maximum 36 months and could acquire positional stability and improvement of facial eathetics.
