Pseudomembranous colitis, caused by altering the normal colonic flora and allowing the multiplication of Clostridium difficile, is an deleterious adverse effect of antibiotics. But it is rarely reported by rifampicin. Rifampicin is one of the first line drug in the treatment of tuberculosis and many patients are exposed to its potential adverse effects. We experienced a patient that had abdominal discomfort and hematochezia due to pseudomembranous colitis after receiving antituberculous medication, and which was probably caused by rifampicin. A 82 years old man was admitted with abdominal discomfort and hematochezia for one week. On the past history he had been diagnosed as endobronchial tuberculosis about 4 months ago. Colonoscopy revealed multiple discrete whitish mucosal lesion on rectosigmoid colon, and histologic findings were consistent with pseudomembranous colitis. The antituberculous agents were discontinued and vancomycin was administered. The patient's symptoms were resolved within several days. There was no recurrence after reinstitution of the antituberculous agents excluding rifampicin. We report here on a case of pseudomembranous colitis probably due to rifampicin.

Purpose : To determine the usefullness of transcatheter embolization of arterial bleeding in patients with pelvic bone fracture. Materials and Methods : Between March 2003 and December 2004, we evaluated 13 injuried arteries of eight patients with pelvic bone fracture, All patients underwent angiography, followed by transcatheter arterial embolization using gelfoam. We investigated the vital sign, survival rate and complication of transcatheter arterial embolization. Results : Angiography revealed extravasation of cantrast media in six patients; extravasation and abrupt cut-off of an artery in two. The injured arteries involved(n=13) were internal pudendal(n=4), obturator(n=3), inferior gluteal(n=3), iliolumbar(n=2) and superior gluteal artery(n=1). Transcather arterial embolization was technically successful and there was no complication in all cases. Old age patients(n=2, >60years) died due to hypovolemia and pulmonary complication. Conclusion : Transcatheter arterial embolization of arterial bleeding is a useful procedure in lowering the mortality and complication in pelvic bone fracture.

In the development of thermal anisotropic materials with natural graphite powder and pitches as raw materials, extruding and hot-press method were investigated. Pitches should be reformed to mesophase pitch precursor by thermal pretreatment for using as a binder, and the heating rate was recommended within 0.2℃/min in the carbonization process. The tensile strength of axial direction of all specimens was about three times larger than that of radial direction and it could be increased about 25-60% by adding 1% chopped carbon fiber. The thermal expansion coefficient of axial direction was about 1/3-1/5 than that of radial direction and the thermal expansion was repressed by adding carbon fiber. The thermal conductivity of carbon fiber added specimens was increased with increasing the temperature, while that of without carbon fiber was decreased. The thermal conductivity of axial direction was about 8.0-4.58 times larger than that of radial direction by adding carbon fiber in the range of 0-400℃. As a general, properties of hot-pressed specimens were better than those of extruded specimens.

This study is purposed to analyse the effects of long-term & one-time 10km running exercise from bone metabolic marker change on bone metabolism. 7 male members(18.6±1.08) from a marathon club were subjected to the study. They were allowed to do long-term 10 km running training once a week for 6 months. And bone metabolism mark was determined according to the respective times : before/after 6 months training, before/after 10 km race, one day after the race, 3 days after the race. The examination items of bone metabolism mark were serum calcium, phosphorus, paratyroid hormone, osteocalcin, calcitonin, alkaline phosphatase in blood and calcium, phosphorus, deoxypyridinolin in urine. The results of study were as follows; 1) There was no change in deoxypyridinolin and alkaline phosphatase but there was significant change in calcitonin, paratyroid hormone and osteocalcin(p<.01). 2) There was no change of Calcium in serum and urine but there was significant change of phosphorus in blood(p<.01). To make a conclusion, it is determined that long-term 10 km running at low intensity and low frequency tends to restrict bone metabolism circulation, but exercise at a little high level activates bone metabolism into building up bones and absorbing bones and finally shows up high bone metabolism circulation, which is inferred to have an effective influence on bone health. It is considered there is a possibility that different exercise intensity, even same kind of exercise, influences on bone metabolism sdifferently.

Generally, the totally paralyzed face can never be made normal by any of the current methods of reconstruction. Careful selection of patients based on sound judgment of what can and cannot be achieved by the proposed surgical technique is paramount to a successful operation and a satisfied patient. The results are related to time of delayed between injury and repair : the shorter the delay the better are the results. The objectives in correcting facial paralysis are to achieve normal appearance at rest ; symmetry with voluntary motion ; control of the ocular, oral, and nasal sphincter; symmetry with involuntary emotion and controlled balance when expressing when expressing emotion ; and no significant functional deficit secondary to the reconstructive surgery. It must be employed a number of concepts, for treatment of the paralyzed face by surgeon, depending on the cause, time interval, and wound characteristics, as well as the availability of and necessity for neuromuscular substitution. Nerve grafts, crossovers, muscle transfers, free muscle and nerve-muscle grafts, micronuerovascular muscle transfers, and regional muscle transpostion are the principal methods being developed. We applied the tmporal musle transposition for reanimation of unilatrally paralyzed faces for long times on two patients. The results of muscle transposition can be enhanced by the patient's learning to activate the transposed muscle by voluntary effort, and are best in patients who are motivated to learn the necessary motor-sensory coordination techniques.
