Journal of Korean Academy of Adult Nursing 1997;9(1):33-43
The Purpose of this study was to obtain the basic data to identify effective nursing methods for intravenous therapy patients by means of investigating the incidence of phlebitis and identifying the risk factors for intravenous-related phlebitis which cared by the IV team nurses. The data collected from August, 30, 1995 to October, 2, 1995. The subjects of this study were 495 IV catheters of 270 patients hospitalized to the 3 internal medicine and the 3 surgical wards of large general hospital who received the continuous IV therapy. In order to investigate the incidence of phlebitis, investigator developed the criteria for judging phlebitis and assessment records concerning the phlebitis. Catheter sites was inspected on a daily basis by IV team nurses, and development of phlebitis was graded and documented. The data were analyzed using the PC-SAS program : Percentages and Chi-Square test were used. The results were summarized as follows ; 1. Over-all rate of incidence of intravenous-related phlebitis was 8.7%(Grade III 8.5%, Grade IV 0.2%). 2. There was significant difference in the incidence of phlebitis by sex. It was 12.00% in female as compared to 6.44% in male. 3. There was no significant difference in the incidence of phlebitis by age. 4. There was significant difference in the incidence of phlebitis according to duration of catheter placement. The incidence of phlebitis was the highest within 24 hour after insertion. 5. There was significant difference in the incidence of phlebitis according to the location of the insertion site. Lower extremities were 22.22% as compared to 8.18% in upper extremities. But, there was no difference in the incidence of phlebitis according to the location of the insertion site among upper extremities catheters. 6. There was significant difference in the incidence of phlebitis by the size of cannula 22G was 11.08% as compared to 4.14% in 18G. 7. There was no significant difference in the incidence of phlebitis between surgical and medical wards. It was 10.96% in surgical wards as compared to 6.88% in medical wards. In conclusion, the following risk factors can be attributed to the incidence of phlebitis : sex, the duration of catheter placement, the location of the insertion site and the size of cannula inserted. Consequently, in order to prevent and detect the intravenous-related phlebitis early, a consistent, organized assessment and evaluation of the above factors during the intravenous therapy.

5.An experimental study on the alteration of thermal enhancement ratio by combination of split dose hyperthermia irradiation
Journal of the Korean Radiological Society 1983;19(2):289-302
The study was undertaken to evaluate the alteration of thermal enhancement ratio as a function of timeintervals between two split dose hyperthermias followed by irradiation. For the experiments, 330 mice were dividedinto 3 groups; the first, 72 mice were used to evaluate the heat reaction by single dose hyperthermia and heatresistance by split dose hyperthermia, the second, 36 mice were used to evaluate the radiation reaction byirradiation only, and the third, 222 mice were used for TER observation by comibination of single dosehyperthermia and irradiation , and TER alteration by combination of split dose hyperthermia and irradiation. Foreach group the skin reaction score of mouse tail was used for observation and evaluation of the results of heatand irradiation. The results obtained are summarized as follows; 1. The heating time resulting 50% necrosis(ND 50)was 101 minutes in 43degrees centigrade and 24 minutes in 45degrees centigrade hyperthermia, which indicated thatthere is reciprocal proportion between temperature and heating time. 2. Development of heat resistance wasobserved by split dose hyperthermia. 3. The degree of skin reaction by irradiation only was increasedporportionally as a function of radiation dose, and calculated radiation dose corresponding to skin score 1.5(D1.5) was 4,137 rads. 4. Obtained thermal enhancement ratio by combination of single dose hyperthermia andirradiation was increased proportionally as a function of heating time. 5. Thermal enhancement ratio was decreasedby combination of split dose hyperthermia and irradiation , which was less intense and lasted longer thandevelopment of heat resistance. In summary, these studies indicate that the alteration of thermal enhancementratio has influence on heat resistance by split dose hyperthermia and irradiation.

Metformin is widely marketed medication for the treatment of diabetes, but its pharmacological effect on diabetic peripheral neuropathy remains unclear. In this study, the effect of metformin on peripheral nerves in diabetic rats was investigated using diverse neuronal parameters of nerve fibers. Rats were assigned to one of four groups ( Both DM+metformin and DM+ALA groups showed similar trends to diverse sensory tests at 24 weeks compared to DM group although the degree of change were different according to the stimulated senses. There was no significant difference in the comparison of the intraepidermal nerve fiber density (IENFD) of peripheral nerves between the DM+metformin and DM+ALA groups (11.83±0.07 fibers/mm vs. 12.37±1.82 fibers/mm, respectively). Both groups showed preserved IENFD significantly compared with DM group (8.46±1.98 fibers/mm, Metformin has beneficial pharmacological effects on the preservation of peripheral nerves in diabetic rats and its effects are comparable to those of ALA.

Since the placenta is an organ composed of blood vessels, it is not surprising that its primary neoplasm would be a vascular tumor. Placental tumors, primary or secondary, have been known to interfere with placental function. Chorioangioma(primary tumor of the placenta), which is the most common of them, occurs with an incidence for clinically significant ranges from 1~2.8:10000 births. These tumors are benign and are not usually associated with clinical sequelae unless they are larger than 5cm in long diameter. About one third of the large chorioangiomas may be associated with the maternal and fetal complications. For diagnosis of these lesions, the ultrasonography was used. If the chorioangioma is suspected, color doppler study is informative to confirm the presence of the vascular channels. We reviewed ultrasonograms and clinical records of seven patients who had been diagnosed as placental chrioangioma. The appropriate diagnostic tests and treatment can then be initiated in order to prolong gestation and decrease fetal mortality and morbidity.

BACKGROUND: Through the control of tuberculosis at 22 public health centers under the National Tuberculosis Control Program, this study is purposed to examine the situation of the tuberculous patients and the characteristics of the therapeutic regimens. METHODS: The data was obtained from 8091 medical records of pulmonary tuberculous patients who were registered for treatment at public health center in Seoul during the year of 1993. It was comparatively analysed by the general characteristics(gender, age, chest X-ray findings, sputum results, treatment results, side effects, combined diseases and accompanied extra-pulmonary tuberculosis) according to various regimens of the tuberculosis. RESULTS: The male patients were 5144, the female were 2947. 34.1% of patients were between 21 and 30years of age. Short course regimen was 97.1% and long course regimen was 2.9%. According to chest X-ray findings minimal 53.5%, moderately advanced 41.2%, far advanced 5.3%. Sputum AFB negative was 52.2% and positive was 47.8%. Therapeutic efficiency was high in short course regimen. Among the side effects, dermatologic problems was high and at the regimen of EHRZ side effects were developed highly. Combined diseases were liver diseases(5.2%), DM(4.2%). Accompanied extrapulmonary tuberculosis were pleurisy(5.4% ), superficial lymphadenitis(0.4% ). CONCLUSIONS: There was great effects in the treatment of tuberculosis with short course regimen in the National Tuberculosis Control Program. But only 38% among the expected patients were treated in this country. So the greater efforts were needed to find and treat more patients effectively.

Epstein-Barr virus (EBV) has been linked to a spectrum of neoplastic conditions, including Burkitt's lymphoma, nasopharyngeal carcinoma, Hodgkin's disease, lymphoepithelioma-like carcinomas and malignant lymphomas in immunocompromised state. To determine the prevalence and the subtype of EBV in gatrointestinal malignancies, fifty cases of adenocarcinomas and seventeen cases of malignant lymphomas were analyzed by EBERs in situ hybridization and polymerase chain reaction using primers for EBNA-1, EBNA-2A and EBNA-2B, on the paraffin sections. In addition, immunohistochemical stain for p53 protein was performed to investigate the potential role of EBV infection on tumor suppressor gene, p53, during tumorigenesis. EBER was detected in 6 of 26 gastric adenocarcinomas, 2 of 24 colon adenocarcinomas, and 8 of 17 malignant lymphomas. EBER was more prevalent in malignant lymphoma arising in the intestine (6/6) than in the stomach (2/11), and was detected in both B and T cell phenotypes. EBNA-1 was positive in 11 of 16 EBER positive cases and the subtyping was possible in 8; both type 1 and 2 were detected in gastric cancers, whereas only type 2 was found in intestinal neoplasms. In adenocarcinomas the high rate of p53 protein overexpression was found in both EBER positive (8/8) and negative cases (32/42), whereas the positive rate was higher in EBER positive cases (7/8) than in EBER negative cases (4/9) of malignant lymphomas. From the results, it can be concluded that EBV infection and the p53 tumor suppressor gene are independently associated in a significant portion of the gastrointestinal malignancies, but the mechanism of action remains to be elucidated.
