This study was designed to analyse effects of Family Health Workers' activities on the performance of a child immunization program an part of the evaluative research in the community health demonstration project in Kang Wha. Frequent shortcomings of evaluative research are problems in setting evaluative indices, difficulties in interpreting influences of socioeconomic changes due to lack of control and failure of demonstrating association between activity input and program performance. Specific objectives of this study was to improve the frequent shortcoming of evaluative research by isolating the effects of Family Health Workers' activities on the performance of the program through controlling other variable which also influenced the program performance. The target population consisted of 1240 children who were born between Jan. 1971 and Dec. 1075 in Sunwon Myun, and Naega Myun in Kwahg Wha Gun, Kyonggi Province. The data were collected in part through 20 Family Health Workers who interviewed the mothers of these children in their villages during Nov. 1977. Part of the data were obtained by summarizing Family Health Workers daily activity records. All data were grouped for each birth cohort according to the 20 villages. Dependent variable of the model is the measle immunization rate of each village and the independent variables are characteristics of baby, mother, household, travel time to the health sub-center, to Kang Wha Town, and the mean member of visits to the household by Family Health Workers as well as their other related activities and the year of birth of children according to village. The model was analysed by stepwise multiple regression technique. The summarized results show that overall R2 were 39.3% and mean number of Family Health Worker household visits, mean age of mother and mean economic status were significant variables in explaining the immunization rate. Therefore Family Health Workers' activities are one of the significant variables in influencing the increased immunization rate of children in villages of the project area.

PURPOSE: Numerous studies have been performed about the various safety consideration of magnetic resonance(MR). Multiple investigators have failed to reveal any deleterious defects of MR. On the other hand, several studies have demonstrated detectable biologic effects of high-field MR produces any morphologic changes on the cell membrane and intracellular ultrastructures in human peripheral blood lymphocytes in vitro. MATERIALS AND METHODS: Lymphocytes were isolated from peripheral blood of normal human adults by Ficoll-Hypaque density centrifugation. Exposure to MR was performed with 4.69T and 11.74T MR spectrometer with a radio frequency(RF) pulse of 200MHz and 500MHz. Exposure times varyed from 30 minutes to 3 hours. The cells were fixed immediately, 1, 3, 7 days after MR exposure. Morphologic evaluation was examined by transmission electron microscopy(TEM). RESULTS: Under TEM there was cell transformation including cellular membrane, nucleus and intracellular microorganelles on lymphocytes exposed to MR. The percentage of transformed lymphocytes was not significantly increased after 4.69T MR exposure, whereas the percentage of transformed lymphocytes was significant increased after 11.74T MR exposure(P<0.05) compared with that of control. The percentage of transformed lymphocytes was significantly increased at the long incubation period in control and MR exposure group(P<0.05). No change according to MR exposure time and RF pulse sequence was noted. CONCLUSION: Exposure to high-field MR induces morphologic transformations of lymphocytes in vitro. Additional studies have to be performed before definitive conclusion can be reached about the safety of high-field MR.

Occupational asthma induced by the inhalation of the spore of Ganoderma lucidum was demonstrated in a 43-year-old woman who had cultivated it indoors for 6 years. She had suffered from paroxysmal cough and rarely wheezing dyspnea for two years. Recently she also had chest tightness and paroxysmal and repeated cough immediately after the exposure to Ganoderma lucidum spores. Her pulmonary function was normal. But, her PC20 was 6.4mg/ml in MBPT (methacholine bronchial provocation test). She showed not only positive reaction to skin prick test but also dual asthmatic reaction to the bronchial challenge test with antigenic extract of Ganoderma lucidum spores.

To observe whether the measurement of enzyme activity has any critical role in assesment of diagnostic value, beta-glucuronidase and lactic dehydrogenase activities in neoplastic tissue of stomach were compared with those in the stomach at the stomach mucosa at the antrum and body which was uninvolved by tumor. And then activities of those enzymes were also compared with differentiated and undifferentiated carcinomas. The stomach tested were obtained by gastrectomy in Pusan National University Hospital during the months from March to June in 1983. The results were summarized as follows: 1) beta-glucuronidase activity in the neoplastic tissue of stomach was higher than that in the antral and body mucosa, and this enzyme activity in the antral mucosa with intestinal metaplasia was higher than that in the body mucosa of stomach. 2) Lactic dehydrogenase activity in the neoplastic tissue of stomach was similar to that in the antral mucosa with intestinal metaplasia, and was higher than that in the body mucosa of stomach. 3) Acitivities of both enzymes in the neoplastic tissue of differentiated carcinoma were slightly higher than that of undifferentiated one, but did not found statistically significant difference. 4) In the neoplastic tissue of the stomach there was no significant correlation between beta-glucuronidase and latic dehydrogenase activities. Above results support that the measurement of gastric juice enzymes is useful in the diagnosis of stomach carcinoma and may be of value in the identification of high-risk groups.

We report a case of bacteriologically proven salmonella infection on the thoracic vertebra in a patient with previous history of pulmonary tuberculosis, in the non-endemic area with no history of sickle cell disease and typhoid fever. A forty-three years old female patient was admitted because of severe back pain, chest pain, lower extremity weakness and intermittent high fever elevation. On plain X-ray there was narrowing of T11-12 disc space with adjacent vertebral body destruction localized centrally around the disc and paravertebral abscess. She had an old history of pulmonary tuberculosis and treated with antituberculosis medication twenty years ago. We treated this patient by abscess drainage, anterior curettage and iliac corticocancellous strut bone graft over the T11 to T12 by anterior transthoracic approach. Histopathological diagnosis was chronic vertebral osteomyelitis with chronic inflammatory reaction. Pus culture reported to have grown salmonella typhi group D, sensitive to ampicillin, chloramphenicol, gentamicin and tetracycline. We could establish the diagnosis and effectively treat the disease with early surgical intervention.

PURPOSE: To evaluate the degree of injury of the spinal cord in relation with the space available for the spinal cord at the level of injury, the sagittal diameter of the spinal canal at the uninjured levels, and the Pavlov ratio at the uninjured levels in fractures and dislocations of the lower cervical spine. MATERIALS AND METHODS: We retrospectively reviewed the records and radiographs of patients who had sustained an acute fracture or dislocation of the cervical spine from 1990 to 1995. We collected patients from Orthopedic and Neurosurgical department of Chonbuk University Hospital and at Orthopedic department of Presbyterian Medical Center. Of the 69 patients analyzed, twelve had no neurological deficit, eleven had an isolated nerve-root injury, twenty-two had an incomplete injury of the spinal cord, and twenty-four had a complete injury. We measured above three parameters from the plain lateral radiographs and assessed the difference by one-way ANOVA and unpaired t-test. RESULTS: 1. The mean space available for the spinal cord at the level of injury was 12.9 millimeter for the complete injury of the spinal cord,13.8 millimeter for the incomplete injury, 14.7 millimeter for an isolated nerve-root injury, and 15.7 millimeter for no neurological deficit group. The overall difference among the groups was significant (F=6.98, P=0.0004). The patients who had a complete injury of the spinal cord and those who had an incomplete injury of the spinal cord were significantly different from the patients who had an isolated nerve-root injury and those who had no neurologic deficit (P=0.002). 2. The mean sagittal diameter of the canal at the proximal and distal uninjured level was 14.3 and 14.6 millimeter for the complete injury of the spinal cord, 14.9 and 14.9 millimeter for the incomplete injury, 15.5 and 16.6 millimeter for an isolated nerve-root injury, and 16.9 and 16.5 millimeter for no neurological deficit group. The patients who had a complete injury of the spinal cord and those who had an incomplete injury of the spinal cord were significantly different from the patients who had an isolated nerve-root injury and those who had no neurologic deficit (P=0.001). 3. The mean Pavlov ratio at the proximal and distal uninjured level was 0.90 and 0.86 for no neurologic deficit group, 0.85 and 0.87 for an isolated nerve-root injury, 0.76 and 0.75 for the incomplete injury of the spinal cord, and 0.76 and 0.76 for the complete injury. The patients who had a complete injury of the spinal cord and those who had an incomplete injury of the spinal cord were significantly different from the patients who had an isolated nerve-root injury and those who had no neurologic deficit (P=0.001). CONCLUSIONS: The patients who sustained a permanent injury of the cord usually had had a narrower sagittal diameter (<14mm) and a lower Pavlov ratio (<0.80) of the spinal canal before injury. Patients who had a large sagittal diameter of the canal may be more likely to be spared a permanent injury of the spinal cord following a fracture or dislocation of the cervical spine compared with patients who have a narrow canal. These findings demonstrated that the severity of the injury of the spinal cord was in part associated with the space available for the cord (at risk:<13mm) after the injury, as measured on plain lateral radiographs.
