PURPOSE: This study compared the effects of dual motor task training and simple task training on the balance of subacute stroke patients. METHODS: A total of 23 subacute stroke patients participated in the study. The subjects were allocated randomly to two groups: an experimental group and a control group. Both groups received conventional treatment for 50 minutes, 5 times per week for 6 weeks. In addition, the experimental group stacked blocks, moved catch cups, and moved rings while standing and gait. To evaluate the effects of the exercises, subjects were evaluated by using the balance system and the timed get up and go test(TUG) for balance measurement. The data was analyzed using a paired t-test and independent t-test to determine the statistical significance. RESULTS: The experimental group showed a significant decrease on the medial-lateral and anterior-posterior stability index compared to the control group (p<.05) for the simple task and a significant decrease on the medial-lateral and anterior-posterior stability index compared to the control group for the dual task. In addition, the experimental group showed a significant increase in TUG time compared to the control group (p<.05). CONCLUSION: These results support the perceived benefits of dual motor task training to augment the balance of subacute stroke patients. Therefore, dual motor task training is recommended for subacute stroke patients.

The present study was conducted to investigate the potential subacute toxicity of AS6, [(3$\beta$, 4$\alpha$)-3,23-dihydroxyurs-12-en-28-oic acid], by a 4-week repeated oral administration in Sprague-Dawley rats. To test the subacute toxicity, AS6 was administered once daily by gavage to rats at dose levels of 0, 250, 500, and 1000 mg/kg/day for 4 weeks. There were no treatment-related effects on mortality, clinical signs, body weight, food and water consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, necropsy findings, organ weights, and histopathology in any treatment group. In the condition of this study, target organ was not observed and the no-observed-adverse-effect level (NOAEL) was considered to be 1000 mg/kg/day for both male and female rats.

Background: Enlargement of subdural hematomas is relatively rapid in subacute stage of hematoma with clinical deterioration, which eventually necessitates surgery. The purpose of this study is to investigate the feasibility and safety of burr hole drainage using urokinase for management of patients with subacute subdural hematoma (SASDH). Methods: Nine patients with SASDH were treated by burr hole drainage using urokinase. Under local anesthesia a catheter was inserted into the hematoma through a burr hole. Burr hole drainage was followed by hematoma thrombolysis with instillation of urokinase (10,000 units) every 12 hours. Drainage was discontinued when a significant decrease of hematoma was observed on cranial computed tomography. Results: The patients' median age was 70 years (range, 62-87). The median Glasgow Coma Scale score before surgery was 15 (range, 11-15). Drainage was successfully performed in all patients. All patients had Glasgow Outcome Scale scores of 5 at discharge. There was no surgery-related morbidity or mortality. Conclusion: A burr hole drainage using urokinase could be a safe, feasible and effective minimally invasive method with low morbidity in treatment of selected patients with SASDHs.

The Three months subacute toxicity of water soluble dimethyl dimethoxy biphenylate derivative (DDB-S), newly formulated therapeutic agent for hepatitis, was invesgated in SD rats. The body weight and clinical signs were observed after intravenous injection of DDBs at doses of 57, 75 and 100 mg/kg/day for three months. Decrease in motor activity and tremor were observed above 75mg/kg treated groups. Statistically significant changes at serum biochemical analysis were found in some group, how-ever, those changes were within the normal range and had no relationship with dosage. There was no abnormal morphological and pathological findings in relation to DDB-S treatment. The no observable adverse effect level of DDB-S in rats was estimated to be 57 mg/kg/day in this study.

Single and 4 weeks oral administration of New wonbangwoohwangchungsimwon (NSCH) which was used l-muscone as substitutive material qf musk, to beagle dogs of both sexes were per-formed to investigate both acute and subacute toxicity. Beagle dogs (3 males and 3 females) in acute experiments were administered orally with single dose of 2,000 mg/kg and groups of 9 male and 9 female beagle dogs in subacute experiments were given daily different dosage of NSCH, 160 mg/kg/day (low dosage group), 400 mg/kg/day (middle dosage group), 1,000 mg/kg/day (high dosage group) once a day for 4 weeks by oral route according to the Established Regulation of Korea Food and Drug Ad-ministration (l996. 4. 16). $LD_{50}$ value for beagle dogs was more than 2,000 mg/kg per oral for both male and females. In animals administered with NSCH, there were neither dead animals nor significant changes of body weights. In addition, no differences were found between control and treated groups in clinical sign, urinalysis, eye examination, hematology, serum chemistry, organ weight and other fingings. No histological lesions were observed in both control and treatment groups. Above data strongly suggset that NSCH in beagle dogs is considered to be safe.

The aim of this study was to investigate whether repetitive transcranial magnetic stimulation (rTMS) can improve motor recovery in the lower extremities of the patients with subacute stage spinal cord injury (SCI). This study was conducted with 19 subjects diagnosed with paraplegia because of SCI. The experimental group included 10 subjects who underwent active rTMS, and the control group included 9 subjects who underwent sham rTMS. The SCI patients in the experimental group underwent conventional rehabilitation therapy, and active rTMS was applied daily to the hotspot of the lesional hemisphere. The SCI patients in the control group underwent sham rTMS and conventional rehabilitation therapy. The participants in both the groups received therapy five days per week for six weeks. Latency, amplitude, and velocity were assessed before and after the six-week therapy period. A significant difference in post-treatment gains for the latency and velocity was observed between the experimental and control groups (p < 0.05). However, no significant differences in the amplitude were observed between the two groups (p > 0.05). The results of this study indicate that rTMS may be beneficial in improving motor recovery in the lower extremities of subacute stage SCI patients.

Single and 4 weeks oral administration of l-muscone, a major active ingredient of musk, to beagle dogs of both sexes were performed to investigate both acute and subacute toxicity. Beagle dogs(3 males and 3 females) in acute experiments were administered orally with single dosage of 2,000 mg/kg and groups of 9 male and 9 female beagle dogs in subacute experiments were given daily different dosage of l-muscone, 0.2 mg/kg/day(low dosage group), 2 mg/kg/day(middle dosage group), or 20 mg/kg/day(high dosage group) once a day for 4 weeks by oral route according to the Established Regulation of Korean Food and Drug Administration(1996.4.16). $LD_{50}$ value for beagle dogs was more than 2,000 mg/kg on oral route for both male and females. In animals administered with l-muscone, there were neither dead animals nor significant changes of body weights. In addition, no differences were found between control and treated groups in clinical signs, urinalysis, eye examination, hematology, serum chemistry, organ weight and other findings. No histolopathological lesions were observed in both control and treatment groups. Above data strongly suggest that l-muscone in beagle dogs is considered to be safe.
