We report the efficacy of catheter-directed thrombolysis (CDT) for acute deep vein thrombosis. Between January 2003 and August 2004, 20 patients were treated with CDT for occlusive femoral, ilio-femoral and vena caval thrombosis, for less than 2 weeks from onset. Average age was 56.4 years (range 30-78 years), 11 patients were male, and the duration of leg symptoms was 4.4 days (range 1-12 days). Routine temporary inferior vena caval filters were used, and a multi-lumen catheter was inserted from the popliteal vein. Urokinase was used via the catheter by the combination drip infusion method and pulse-spray method. All patients received heparin and stasis of venous flow was prevented with intermittent pneumatic compression. If thrombus remained, mechanical thrombolysis was necessary. Metallic stents were implanted for iliac vein compression syndrome and organized thrombus. Venographic severity score (VS score) and extremity circumference were used to evaluate the effects of treatment. The duration of the treatment was 5.0±0.28 days (range 2-9 days) and the total dosage of urokinase was 1, 025, 000±57, 000 units (range 360, 000-1, 680, 000 unit). One (5%) iliac vein compression syndrome and two (10%) organized thrombi were treated by implanted metallic stents. Giant thrombi was captured by temporary inferior vena caval filters in two patients, but there was no pulmonary embolism. Two patients had thrombophilia, one was antiphospholipid syndrome and one was protein S deficiency. There was an early recurrence in one patient and re-CDT was needed. The VS score deteriorated to 6.2±2.5 (post CDT) significantly (p<0.0001) from 26.2±6.3 (pre CDT). CDT for acute deep vein thrombosis was effective and its early outcome was acceptable.

We purified a novel angiotensin-I converting enzyme (ACE) inhibitor from fish sauce Ishiru prepared from squid, and identified it as the tripeptide Leu-Ala-Arg (LAR). IC₅₀ of this ACE inhibitor was 2.5 μM, demonstrating high potency among peptides previously purified from fish sauces. Moreover, LAR acted as an antihypertensive peptide, reducing systolic blood pressure in spontaneously hypertensive rats.

  To the best of our knowledge, there are few reports on acquirement of medical skills of infection control using a scenario simulation program. We report the development of a education program using scenario-based simulation named Infection Control Training Course （ICTC）. The three main aims of this course are basic comprehension of standard precautions and contact precautions, acquirement of skills for wearing and removal of personal protective equipment （PPE）, and precise selection of PPE for various situations.
・For the materials and methods, 225 medical staff members taking part in the ICTC at TMU participated in the study. Investigations using a questionnaire about standard precaution, contact precaution and PPE selection were carried out for the pre-course and post-course of the day. In addition, the satisfaction level was evaluated using free score text.
・The return rates of the completed questionnaire for investigating these areas were 88.4% （pre-course） and 95.1% （post-course）. Among all the items investigated, improvements were verified statistically （Wilcoxon signed-rank test）. The satisfaction level was 94.7 ± 9.4 points.
・In conclusion, the ICTC was considered to be effective for acquiring medical skills of infection control, particularly basic comprehension regarding standard precaution, contact precaution and precise PPE selection using a scenario simulation program.

Results: In the early phase after surgery, 71% and 43% of the participants were nonindependent ambulators at 1W and 2W, respectively. Histopathology indicated that patients with solid tumors (ependymoma, astrocytoma, or lipoma) showed significantly lower indices at 1W and 2W than those with vascular tumors (hemangioblastoma or cavernous hemangioma). Regarding tumor location, thoracic cases exhibited poorer lower-limb function at 1W and 2W and poorer walking ability at 2W than cervical cases. According to the receiver operating characteristic (ROC) analysis, 2 WISCI II points at 2W had the highest sensitivity (100%) and specificity (92.2%) in predicting the level of walking independence at 1 year postoperatively (the area under the ROC curve was 0.99 (95% confidence interval, 0.93–1.00). Conclusions The higher the lower-limb function scores in the early phase, the better the improvement in walking ability is predicted 1 year after ISCT resection.

A statistical study on effects of laser-puncture was carried out. In addition, an attempt was made to compare between the effect of acupuncture and this method. The treatments were under-taken for various chronic and acute cases with pain. In the laser-puncture treatment, two types of laser (i, e. low energy 10mW laser and 70mW sharp laser) were used. Laser-beam was given to 20-30 points which were located in painful areas, innervating nerve areas and remote areas for 40 sec for each.
In the open study, 10mW laser-puncture was effective (including ‘rather effective’) in 64% of the cases, and 70mW laser-puncture 73%. In the blind test, ‘the day’ evaluation showed that the laser-punctures were more effective than placebo treatment: 10mW laser-puncture was effective in 80% of the cases, and placebo in 67%. 70mW laser-puncture was effective in 87% of them, and placebo in 80%. In situ acupuncture was effective in 97%, and no effect was seen in 7%.
Only ‘the day’ evaluation in the open study showed that 70mW laser-puncture was more effective than 10mW one. In the blind best, 10mW and 70mW laser-puncture were more effective than placebo, and in situ acupuncture was more effective than the laser-punctures, but there were no significant differences among the three treatmets.
