Simple bone cyst was first described by Virchow over a century ago and has been the subject of numerous articles. Nevertheless considerable confusion still exists regarding its etiology. clinical behavior and optimal management. Eighteen cases of pathologically proven simple bone cyst were treated in the Department of Orthopedic Surgery, Seoul National University Hospital during the thirteen year period from June 1966 to May 1979, and following results were obtained. 1. Age distributions were between five and forty-three years (Average ; seventeen years), and 72.2% (thirteen cases) were during first two decades of life. 2. Male to female ratio was 2.6 to 1 3. The most frequently involved location was proximal humerus followed by proximal femur. 4. Pathologic fracture, pain, incidental roentgenography and swelling were the first clues of diagnosis in our series. 5. In twelve cases curettage and fresh autogenous iliac bone graft was performed and good results were obtained in all of them. Of five cases only curettage had been done, no case recurred, another case showed residual cystic area, and the rest healed without further event. In one case with huge cyst curettage, iliac and fibular bone graft and bone cementing was performed with satisfactory result. 6. Bone shortening was noticed in two cases of active bone cysts in proximal humerus 2cm and 3cm, respectively.

Although the incidence of tuberculosis of the bone and joints is being decreased with good nutrition, hygine and the development of preventive medicine, it is still a common disease in our clinic. One hundred and ninty-eight cases of tuberculosis of the bone and joints were studied in the Department of Orthopedic Surgery, Seoul National University Hospital for 10 years from January, 1966 to December. 1975. The results were as follows: 1. Total cases of tuberculosis of the bone and joints were 588 Among them, peripheral bone and joints excluding the spine occupied 198 cases (34%). 2. Sex ratio was 1.7 : 1 (male : female). Age distribution showed the group below 10 years was 78 cases (39%). On the other hand, 7 cases were over 51 years old. 3. More than 50% of patients visited hospital after one year from the onset. 4. One-third of all cases had been given some management before admission and the most common treatment was anti-tuberculous chemotherapy (25%). 5. Erythrocyte sedimentation rate was definitly increased in 41%. 6. Associated tuberculous lesionsoe of extraskeletal system were confirmed in 66 cases (33%). Among them, active pulmonary tuberculosis were 51 cases (77%) 7. Various treatments (conservative, curettage, synovectomy, arthrodesis, etc.) had been carried out. However, surgical managements for saving the range of motion must be considered always before arthrodesis.

BACKGROUND: Recently, there are so many newly developed equipments to detect blood gas analysis with serum electrolytes. And then, so many important parameters are quickly reported from laboratory department. So, many clinicians use the data to manage the critical patient. We attempted to detemine the correlation coefficient and adjustment equation. METHODS: Total 68 patients results of Na, K that are cheked using arterial whole blood(288 blood gas system) and venous serum electrolytes analyzer(NOVA 6) were evaluated and we detemined the coefficient of two methods from April to September, 1995. RESULTS: The correlations between the results obtained with NOVA 6 and that of 288 blood gas system were excellent for both Sodium and potassium(r>0.95, p<0.001 in both). In this study, we make the regression equation to adjust the differences between the two methods. Na : y=1.004190X+7.656643(r=0.9637, p<0.001) y=venous serum Na, x=arterial whole blood Na K: y=0.994831X+0.489631(r=0.9545, p<0.001) y=venous serum K, x=arterial whole blood K. CONCLUSIONS: Specimen(whole blood, serum), kind and content of heparin also affect the results of electrolytes. And then, the report of the result after adjustment of them using above equation will provide reinforcement of the efficacy of the results using arterial whole blood specmen. We recommend it especially for emergency laboratories for critical test.

Thirteen guinea pigs and 23 rabbits were challenged with 300 metacercariae of Clonorchis sinensis each and the recovery of adult worms and egg counts in feces were compared at 11-13 weeks post-infection in guinea pigs and at 7-9 weeks post-infection in rabbits. The recovery rate of adult worm was 23.5 percent in guinea pigs and 20.l-30.5 percent in rabbits. The mean E.P.G. of these animals in above period of infection was 106 in guinea pigs and 121 in rabbits. When one hundredth of E.P.G. was expressed as X and the number of adult worms as Y, the relationships between X and Y were as follows; Y=0.8X+10.8 in guinea pigs and Y=0.7X+6 in rabbits.

Fifty-two patients of meniscal injury were studied in the Department of Orthopedic Surgery, Seoul National University Hospital for 5 years and 6 months from January, 1973 to June, 1978. The results were as follows: 1. Male was more affected than female (M:F = 1.4:1). And the injury of meniscus was most frequently occurred in the age group between 11 and 30 years old (65.2%). 2. Thirteen patients denied the history of trauma (25.2%). 3. Over-all positive rate of Memurray sign was 85% and arthrography was 74%. 4. Lateral meniscus was more frequently affected than medial meniscus. The most frequent type of lesion was peripheral longitudinal tear (11 cases). Discoid meniscus was found in 14 patients. 5. In follow-up study, satisfactory results were obtained in 84.3%.

The trematode Paramphistomum cervi empolyed in this experiment was obtained from the reticulum of cattle slaughtered at the local abbatoir. The worms were selected and washed several times in normal sterilized saline solution. Each about ten of intact worms were incubated in 50 cc volume of special incubation flasks with incubation mixture consisting of 50 cc of Krebs-Ringer phosohate buffer (pH 7.4) to which were added universally labeled C(14)-glucose and non-radioactive carrier glucose concentration of 200 mg per cent. The worms were allowed to incubate for 3 hours in the incubator at 38 C. After incubation period, respiratory CO(2) samples from central wall of incubation flask were analysed for total CO(2) production rate and their specific activity of respiratory CO(2). Glycogen samples isolated from worms were analysed for the tissue concentration and their radioactivities in order to determine the turnover rate of glycogen pool. The glucose uptake rate was determined by analysing the difference of the glucose concentration in a medium before and after incubation period. Radioactivities of these series of experiments were counted by an endwindow Geiger-Muller counter as an infinitely thin samples. The quantitative analysis of C(14)-glucose utilized by Paramphistomum cervi was summerized as the following. The glucose uptake rate by Paramphistomum was a mean value of 2.32+/-0.27 micro-mole/hr/g of wet wt. and total CO(2) production rate by the worms averaged 10.85+/-0.41 micro-mole/hr/g of wet wt. The relative specific activities of respiratory CO(2) averaged 49.72+/-13.20 per cent. Thus, a mean of 49.72 per cent of total CO(2) production rate was originated from the glucose in the medium, therefore the rate of CO(2) production derived from medium glucose was mean of 5.24+/-2.16 micro-mole/hr/g of wet wt. Thus, the average value of 37.46+/-5.28 per cent of glucose utilized by the worms from the medium glucose was oxidized to respiratory CO(2). The tissue concentration of Paraphismum was a mean of 41.56+/-5.82 micro-mole/hr/g of wet wt or 4.16+/-0.72 per cent/g , and the turnover rate of glycogen pool yielded with a mean of 0.12+/-0.014 percent/hr or 0.06+/-0.04 mg/hr/g of wet wt. Therefore, a mean value of 16.75+/-4.84 per cent of glucose was incorporated to the glycogen. These data account for that at least 54.21 per cent of the utilized glucose by the worms participated in furnishing the oxidation into respiratory CO(2) and the synthetic process into glycogen. According to the above data of the experiment, it is suggested in the metabolic process of glucose by the Paramphistomum that the synthetic process into the glycogen is less active than the oxidative process into the resppiratory CO(2).
