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).

BACKGROUND: Intracoronary stent with various designs have been developed to treat dissections or acute closure after angioplasty. The efficacy of flexible coil stent as a bail-out device has been reported. However, the restenosis after stenting still remained as a main limitation like other devices. This study reports on the angiographic follow-up after successful intracoronary stenting with flexible coil stent. METHOD: From April 1993 through July 1994, coronary stenting was tried in 21 patients by a single operator for various indications(acute or threatened closure, suboptimal result after balloon angioplasty). The nineteen(95%) out of 20 patients in whom stent was successfully deployed underwent follow-up coronary angiography 7.6+/-3.0 months after coronary stenting. RESULT: Mean age was 54.7+/-11.3(33-73) years and 16 parients were men. Clinical diagnosis of patients were as follows : stable angina 7, unstable angina 6, old myocardial infarction with stable angina 6 and acute myocardial infarction in 1 patient, respectively. Stents were implanted at left anterior descending artery in 9, left circumflex artery in 5 and right coronary artery in 8. Ten out of 21 stents(47.6%) were found to be renarrowed more than 50% at follow-up coronary angiography. There was no significant difference in clinical and angiographic variables between restenosis group and no-restenosis group. Coronary artery bypass graft surgery was performed in 1 patient for the treatment of restenosis after stenting. Repeat PTCA was performed in 3 patients and remaining 5 patients were followed medically. CONCLUSION: Flexible coil(Gianturco-Roubin) coronary stent is a useful adjunct percutaneous intervention to prevent or minimize complicatioms associated with dissections. Despite favorable initial angiographic and clinical results, 47.6% of stents were found to be renarrowed significantly at follow-up coronary angiography. New techniques or more optimal characters of stents would be desired.

Ever since the unrelenting efforts of Yasuda to Piezoelectricity, its been one of the hot areas in orthopaedic fields to file up experimental and clinical data concerning treatment of nonunion, delayed union and pseudarthrosis. Clinical use of this theory is the result of a systemic thirty-year investigation of bioelectrical phenomina in the skeletal system and of their role in regulating cellular elements. Since Friedenberys clinical application of Semi-invasive direct current stimulation to nonunion of medial malleolus of tibia, Brighton and Bassett made progress in this field with high success rate. In 1985, Non-invasive capacitive coupled electrical field was developed and used clinically by Brighton. We also developed a model of capacitive coupled electrical field system and made clinical application to nonunion of tibia with successful result.

Twenty nine cases of wrist tuberculosis were reviewed(19 joint involvement cases and 4 tendon involvement cases) and twenty three cases were followed up more than one and half years. The mean follow up period was 26.7 months. Synovectomies were not satisfactory in cases of joint involvement and they were useful only in cases of tendon involvement. Arthrodesises were used for 16 cases of joint involvement and were satisfactory in 87,5 percent by Robin's criteria. Finger stiffness was most serious complication(initially, 8.7 percent and finally, 34.8 percent) and it is suggested that early motion of fingers after arthrodesis can prevent this complication.

Multiple myeloma is a B-cell origin tumor characterized by hypercalcemia, osteolytic bony lesions, and pathologic fractures. Back pain is one of the most common presenting symptoms of multiple myeloma and about 60% of patients have vertebral involvement at the time of diagnosis7). Minimally invasive surgeries such as vertebroplasty and kyphoplasty are effective to relieve pain and improve the quality of life when a compression fracture occurs in multiple myeloma patients. We report a case of continuous multiple compression fractures associated with multiple myeloma. We should check for the possibility of pathologic vertebral fractures resulting from multiple myeloma in non-osteoporotic compression fracture patients, and especially in cases of continuous fracture occurring in relatively non-elderly patients, even though a history of trauma may be present.
