Intraspinal neurenteric cysts are rare congenital lesions that results from abnormal separation of germ layers in the third week of embryonic development, which may cause spinal compression. Although, the diagnosis of neurenteric cyst was very difficult prior to operation, MRI has proven to be a useful imaging modality in detection, localization and characterization of intraspinal neurenteric cysts. We recently experienced intraspinal neurenteric cyst in two patients who presented with progerssive quadriparesis. Myelography, CT myelography and MRI were taken and complete excision was performed. The MRI findings are presented and the literature is reviewed.

To investigate the effect of tumor removal and administration of OK432 on the splenic natural killer (NK) cell activity in the subcutaneous tumor bearing rats, NK cell activity assay using a 4-hour 51Cr release assay and flow cytometric analysis for NK cell population were performed. The results were as follows: 1. Splenic NK cell activity and population in the subcutaneous tumor bearing rats decreased along with the growth of the tumor. 2. The rats with subcutaneous tumor removal showed decrease of splenic NK cell activity, but splenic NK cell population was not decreased. 3. In the rats with subcutaneous tumor removal and OK432 administration, splenic NK cell activity was significantly increased 1 week after administration of OK432 and then gradually returned to normal, whereas increase of NK cell population was not significant. In the present study, splenic NK cell activity was significantly decreased despite removal of subcutaneous tumor. But with the administration of OK432, splenic NK cell activity returned to normal. Considering the role of NK cells on the first line of defense against the metastatic implantation of circulating tumor emboli, we suggest that perioperative administration of immunopotentiator such as OK432 may improve the patient's outcome after surgery of human neoplasm.

Many factors exert an influence on enzyme activity and thus on the rate of reactions that they catalyse. The most important of these factors are pH, temperature, substrate concentration, and the concentration of some inhibitors present. A solution of the enzyme diastase, which breaks down molecules of the polysaccharide starch to the disaccharide maltose by hydrolysis, was provided. Activity of these enzyme was measured by the rate at which starch was removed from the reaction mixture. These experiments were designed to study this reaction rate under varying conditions and the following results were obtained. 1. The range of optimum pH for this enzyme at room temperature was 4.0-7.0 and the optimum pH was 5.0. 2. The range of optimum temperatures for this enzyme at pH 7.0 was 30-50 degrees C and the optimum temperature was 40 degrees C. 3. The relationship between the enzyme activity and substrate concentration could be expressed by the Michaelis-Menten equation. The limiting velocity of these enzyme at room temperature and pH 7.0 was 415 microgram starch removed/ml of reaction mixture/min and Km, Michaelis constant, was 343 microgram/ml. 4. Inhibitors NaCl and HgCl2 blocked this enzyme activity completely at 1% and 0.01% respectively.

Two hundred and eighty six cases of the fracture of the tibial shaft treated at Orthopedic Department of the Chosun University Hospital during the period from January 1974 to December, 1978. The following results were obtained. 1. Most common cases of the tibial shaft fractures were traffic accidents (66.1%). 2. The incidence of trauma was high in the young man, most frequent in the 2nd and 3rd decade (43.0%). 3. The evaluation was done according to the classification of Ellis. Among 286 cases of the fractures of tibial shaft, 139 being mild severity, 70 moderate severity and 77 major severity. 4. The group of mild severity at the fracture of upper 1/3 of tibial shaft was shown the best prognosis and the average healing period was 9.3 weeks. 5. The wound infections in the open fractures of tibial shaft were revealed 37 cases (35%) and 8 cases of chronic osteomyelitis (8%). 6. Of 54 cases, we experienced 38 cases of delayed union (13.3%), 16 cases of non-union (5.6%) and the highest rate of delayed or non-union was shown in the group of major severity at the fracture of lower 1/3 of tibiai shaft. 7. The open reduction by the compression plating reduced the time of healing period and delayed the time of healing period by the intramedullary nailing.
