TS-DP2 is a recombinant human granulocyte colony stimulating factor (rhG-CSF) manufactured by TS Corporation. We conducted a four-week study of TS-DP2 (test article) in repeated intravenous doses in male and female Sprague-Dawley (SD) rats. Lenograstim was used as a reference article and was administered intravenously at a dose of $1000{\mu}g/kg/day$. Rats received TS-DP2 intravenously at doses of 250, 500, and $1000{\mu}g/kg/day$ once daily for 4 weeks, and evaluated following a 2-week recovery period. Edema in the hind limbs and loss of mean body weight and body weight gain were observed in both the highest dose group of TS-DP2 and the lenograstim group in male rats. Fibro-osseous lesions were observed in the lenograstim group in both sexes, and at all groups of TS-DP2 in males, and at doses of TS-DP2 $500{\mu}g/kg/day$ and higher in females. The lesion was considered a toxicological change. Therefore, bone is the primary toxicological target of TS-DP2. The lowest observed adverse effect level (LOAEL) in males was $250{\mu}g/kg/day$, and no observed adverse effect level (NOAEL) in females was $250{\mu}g/kg/day$ in this study. In the toxicokinetic study, the serum concentrations of G-CSF were maintained until 8 hr after administration. The systemic exposures ($AUC_{0-24h}$ and $C_0$) were not markedly different between male and female rats, between the administration periods, or between TS-DP2 and lenograstim. In conclusion, TS-DP2 shows toxicological similarity to lenograstim over 4-weeks of repeated doses in rats.
This study was designed to evaluate the effect of pelvic floor muscle exercise using biofeedback and electrical stimulation after normal vaginal delivery. The data were collected from November 1999 to April 2000 at a university hospital located in Seoul, Korea. Out of 49 women with normal vaginal delivery, 25 of experimental group(with exercise) and 24 of control group(without exercise) were questioned about lower urinary symptoms, discomfort during sexual intercourse and daily life. The maximum pressure of pelvic floor muscle contraction(MPPFMC) and duration of pelvic floor muscle contraction(DPFMC) were measured at pre-treatment, the end of treatment and 8 weeks after a treatment program. The pelvic floor muscle exercise program(using biofeedback and electrical stimulation) was applied to the experimental group twice a week for 4 weeks at the incontinence clinic and the pelvic floor muscle exercise at home for that time and more 8 weeks. Data were analyzed by t-test, $x^2$-test, Fisher's exact test and the repeated measures ANOVA. The results were as follows; 1) MPPFMC(p=0.000) and DPFMC(p=0.021) were significantly increased in the experimental group. 2) In the lower urinary symptoms, daily frequency(p=0.001), nocturia(p=0.002), incontinence episode(p=0.016), stress incontinence(p=0.012), quantity of incontinence(p=0.026), straining(p=0.041), and strength of stream(p=0.009) were significantly decreased in the experimental group. 3) Discomfort during sexual intercourse had not a significant difference between the two groups, which was not significantly decreased as time passed. 4) In the discomfort during daily life, activity restriction(p=0.042), exercise restriction (p=0.008), interpersonal relationship restriction(p=0.046), and discomfort of general life(p=0.027) showed a significant difference between the two groups, which were not significantly decreased as time passed. In conclusion, it is suggested that the pelvic floor muscle exercise using biofeedback and electrical stimulation might be a safer and more effective program for the improvement of postpartum pelvic muscle contraction.
The purpose of this study was to investigate the effects of visual cue deprivation during sideways treadmill training in individuals with stroke. Twenty-eight stroke patients were divided into two groups, and each group participated in a sideways treadmill training session for 20 minutes, three times per week for 4 weeks. The eyes close group (15 subjects) performed this treadmill training with visual cue deprivation, while the eyes open group (13 subjects) performed it without visual cue deprivation. Gait function was measured in both groups before and after the training sessions with the Biodex Gait Trainer 2, which determined walking speed, distance, step length, and time on each foot. Balance was measured before and after each training period in both groups using the Five-Times Sit-to-Stand Test (FTSST), the Timed Up and Go test (TUG), and the seven-item Berg Balance Scale-3P (7-item BBS-3P). The eyes close group showed significantly improved gait function, walking speed, distance, step length, and time on each foot after training (p<.05). The eyes close group showed improved balance ability, FTSST, TUG, and 7-item BBS-3P test after training (p<.05). The findings indicated that sideways treadmill training with visual cue deprivation positively affects gait ability of stroke patients. Therefore, sideways treadmill training with visual cue deprivation may be useful for the recovery of gait ability of stroke patients.
This study aimed to see if as companion animals living with human beings, dogs could provide emotional stability or play a therapeutic role for human beings. Of 12 middle school boys as victims of school violence, 6 were assigned to the experimental group that was provided with an animal-assisted therapy program over a total of 12 sections, one section per week, 60 minutes per section, between September and November 2011, followed by post-test 1 and, one month later, post-test 2. In the experimental composition, the remaining 6 boys were assigned to the comparison group that was allowed to read freely. Analysis was performed by using the scales of depression and self-esteem, and the results showed that the experimental group provided with the animal-assisted therapy program generated more significant therapeutic effects than the comparison group. The therapeutic effects were found to persist one month after the completion of the program. Therefore, it is believed that sensitive adolescents who suffer from depression or have lost self-esteem because of school violence can significantly benefit from an animal-assisted therapy program by reducing the recovery time or by getting lots of help with emotional stability. Further research on the basis of this study is expected to help adolescents with emotional therapy in other areas.
Objective: This study focused on subacute stroke patients who were asked to kick a ball while walking on a treadmill. The aim of the study was to determine the effect of a body weight-supported treadmill training (BWSTT) combined with ball-kicking on muscle strength, balance, and gait. Design: Single blind, randomized controlled trial. Methods: Twenty stroke patients who volunteered to participate in this study were randomly assigned to either the BWSTT combined with ball-kicking (BWSTT-BK; 10 participants) group or the BWSTT group (10 participants). Participants in the BWSTTBK group performed treadmill walking combined with simultaneous ball-kicking for 30 minutes daily for 5 weeks. Participants from the BWSTT group performed only treadmill walking. The muscular strength, balance, and gait ability were measured before and after the 5-week training. To assess for muscular strength, a digital muscle tester was used to measure hip flexor, knee extensor, and dorsiflexor strength. To assess for balance, the Berg Balance Scale (BBS) and Timed Up and Go Test (TUG) was used. To assess for gait, the 10 meter walk test (10MWT) and Functional Gait Assessment (FGA) was used. Results: The BWSTT-BK group showed significantly improved muscular strength, balance, and gait according to BBS, TUG, 10MWT, FGA, and digital muscle testing scores compared to the BWSTT group (p<0.05). In addition, within-group comparison showed significant improvement in all variables (p<0.05). Conclusions: These findings suggest that BWSTT-BK results in more favourable outcomes for stroke patients. Therefore, BWSTT-BK may be useful for the recovery of gait ability of stroke patients.
Objective: The purpose of this study was to investigate the effect of robot arm reach training on upper extremity functional movement in chronic stroke survivors. Design: One group pretest-posttest design. Methods: Thirteen chronic stroke survivors participated in this study. Robot arm reach training was performed with a Whole Arm Manipulator (WAM) and a 120-inch projective display to provide visual and auditory feedback. During the robotic arm reach training, WAM provided gravity compensation and assist-as-needed (AAN) force according to the robot control mode. When a participant could not move the arm toward the target for more than 2 seconds, WAM provided AAN force to reach the desired targets. All patients participated in the training for 40 minutes per day, 3 times a week, for 4 weeks. Main outcome measures were the Fugl-Meyer Assessment (FMA), Action Research Arm Test (ARAT) and Box and Block Test (BBT) to assess upper extremity functional movement. Results: After 4 weeks, significant improvement was observed in upper extremity functional movement (FMA: 42.15 to 46.23, BBT: 12.23 to 14.00, p<0.05). In the subscore analysis of the FMA upper extremity motor function domains, significant improvement was observed in upper extremity and coordination/speed units (p<0.05). However, there were no significant differences in the ARAT. Conclusions: This study showed the positive effects of robot arm reach training on upper extremity functional movement in chronic stroke survivors. In particular, we confirmed that robot arm reach training could have a positive influence by leading to improvement of motor recovery of the proximal upper extremity.

Background: Cassia tora L., an annual or perennial plant of the Fabaceae family, is traditional medicine with various biological activities, including anti-constipation and, anti-inflammation. Chemical compounds such as anthraquinone glycoside and naphthalene derivatives have been isolated from this plant. Cassia tora L. is a common contaminant of agricultural commodities, but is toxic to cattle and poultry. Methods and Results: To investigate the potential toxicity, Cassia tora L. aqueous extract (CO) was administered orally to rats for 26 weeks at 0 (control), 300, 1,500 and 3,000 mg/kg/day (n = 10 for male rats for each dose). The positive control comprised animals orally administered anthraquinone 100 mg/kg/day. There was no treatment-related mortality. An increase in the kidney weight was observed at 3,000 mg/kg/day of CO and anthraquinone 100 mg/kg/day. Macrophage infiltration in the colon was observed at CO 1,500 and 3,000 mg/kg/day and anthraquinone 100 mg/kg/day, but there were no significant toxicological changes in the incidence and severity of the finding. Conclusions: The oral no-observed-adverse-effect level (NOAEL) of CO was 3,000 mg/kg/day in male rats and no target organs were identified. In addition, 300 mg/kg was found to be the no-observed-effect level (NOEL) for systemic toxicity under the conditions of the study.
The effect of ginseng administration on the patients of acute viral (B type) hepatitis has been oberved and the results were as follows. The albumin/globulin ratio of the ginseng administered group has significantly improved 4 weeks after admission while that of control group has not been improved suggesting that the ginseng might be effective in improving the protein metabolism. The thymol turbidity test again gave a similar result. Recovery of the disorder of bilirubin metabolism was also accelerated in the ginseng administered group compared with control group. The raised bilirubin value of the former returnedto the normal value 2 week after admission while that of the latter reached to normal 4-5 weeks after admission. However no significant difference of the bilirubin level between ginseng treated and non-treated groups could be observed. Cholesterol metabolism is also stimulated in ginseng administered group. The lowered cholesterol level of the ginseng group returned to normal 3-4 weeks after admission while that of latter reached to normal 5-6 weeks after admission. The raised S-GOT and S-GPT levels of the ginseng treated group returned to the normal value 3-4 weeks after admission while those of control group rehimed to normal in 5 weeks after admission suggesting that the ginseng improved impaired liver function. The improvement of the raised transaminase level seemed to be accelerate6 by the ginseng administration, however, no significant difference of the transaminase level between the ginseng treated and non-treated group could be observed. A significant effect of ginseng on the raised alkaline phosphatase level was observed. From the above results, it seemed that ginseng might stimulate the improvement of the disturbance of liver function, particularly at the early phase of its development of acute liver disease suggesting that panax ginseng might play a significant role in preventing the disease developing to be chronic.

Four cases of pulmonary pseudallescheriasis in patients with healed pulmonary tuberculosis are described. All four patients had a long history of antituberculous chemotherapy for pulmonary tuberculosis, but continuous sputum negativity for acid fast bacilli indicated apparent recovery from tuberculosis. They, however, complained continued intermittent hemoptysis and chronic cough. Although their chest roentgenograms did not show a clearcut mycetomal shadows in preformed cavitary lung lesions, Pseudallescheria boydii or Scedosporium apiospermum was repeatedly isolated from serial sputum specimens collected at different days for a period of over half an year or two years and their serial serum specimens produced precipitin bands with home-made antigen from 8-week old culture filtrate of P. boydii. Second fungus was isolated from sputum specimens of two patients and one was Candida albicans and the other was Aspergillus fumigatus. Sera from both patients reacted with antigens of those second fungi. Unfortunately pulmonary function of three patients did not allow surgical excision of the infected area and one patient refused surgery.

Purpose : The purpose of this study was to examine the effect of task-oriented circuit training using unstable support surface on balance, gait ability, and balance confidence in subacute stroke patients. Methods : Forty-five patients with subacute stroke were randomly divided into the three following groups of 15: 1) TOCT-US group; task-oriented circuit training using unstable surface (experimental group 1), 2) TOCT-SS group; task-oriented circuit training using stable surface (experimental group 2), and 3) CON group; conventional physical therapy (control group). All patients participated in one of the three training programs for 6 weeks, 30 minutes per session, 3 times per week. Patients' balance ability was assessed using the BT-4, BBS (berg balance scale), TUG (time up and go test), and LOS (limit of stability). Gait speed was measured to examine gait ability. K-ABC (activities-specific balance confidence scale) was also used to assess the level of patients' confidence in daily activities. Results : After the intervention, the sway area in experimental groups 1 and 2 decreased, but that in the control group increased. Experimental group 1 showed significant improvement compared with experimental group 2 and the control group. BBS, TUG, and LOS scores of experimental group 1 were significantly improved compared with those of experimental group 2 and the control group. Also, gait speed significantly improved in experimental group 1 compared with experimental group 2 and the control group. Experimental groups 1 and 2 showed significant improvement in K-ABC scores after training. Conclusion : Patients with subacute stroke had significantly improved balance, gait, and level of confidence in performing activities of daily living following task-oriented circuit training using the unstable surface. This indicates that task-oriented circuit training using unstable surfaces can be an effective treatment method for the recovery of balance and gait in subacute stroke patients.
