  • Objective: Low level laser treatment (LLLT) is widely used in physical therapy practice. It is combined with physical therapy or LLLT alone. The purpose of this study is to evaluate the effectiveness of LLLT on patients' perception of general wrist pain. Design: Longitudinal study. Methods: Forty-eight subjects with wrist pain who were in the age range of 18-70 years old were examined. The subjects were asked, via an interview and a visual analog scale, to grade their wrist pain. They were asked to rotate their wrists through full range of motion and the angle at which any pain occurred was assessed. Each subject was then exposed to one of the following: 1) treatment with an infrared laser with the power turned off (placebo), 2) treatment with an infrared therapeutic laser, 3) treatment with a red therapeutic laser, 4) treatment with an ultraviolet laser, 5) treatment with a blue laser, 6) treatment with a Mickey Mouse flashlight. The duration of the treatment was 3 sessions in 3 days. Results: The results of the experiments showed that while pain was reduced both immediately after and the next day after laser therapy (p<0.05), there was no significant difference between the laser groups and the placebo group. However, the Mickey Mouse flashlight treatment groups had a greater range of motion than the laser groups (p<0.05). Conclusions: While pain was reduced in all laser groups, it was probably a placebo effect. The Mickey Mouse flashlight group probably received benefit from the heat of the flashlight.

  • This study has its own goal to deliver the accurate dose on the target volume by calculating and modifying the attenuation rate of photon beam transmitting the couch top with geometric model. The experiment was that the transmission rate and attenuation rate of photon beam transmitting the couch top was predicted by the geometric model, then compared and analyzed with what was measured experimentally based on that. The result showed that the predicted value by the geometric model accorded closely with the experimental value. In addition, in order to judge whether the practical clinical application is available, the point dose, measured after modifying the attenuation rate modelinged according to the treatment plan of a patient of spine radiosurgery, was compared with the one done nothing. The result was that the former showed decreased error range with treatment planned one than the latter. This papers calculated the transmission and attenuation rate with the geometric model transmitting the couch top and verified it experimentally. This method is expected to be very useful in not only the radiosurgery using Novalis but also the general radiation therapy.

  • Transdermal drug delivery offers various advantages over conventional drug delivery systems, such as avoidance gastrointestinal degradation and hepatic first-pass effect. encourages patient compliance. and possible sustained release of drugs. However, transdermal transport of drugs is low permeability of the stratum corneum, the superficial layer of the skin. Many physicochemical and biological factors influencing transdermal transport is described together with the corresponding experimental and clinical results. Phonophoresis is medical treatment with drugs introduced into the skin by ultrasound energy. Enhanced drug penetration is through to result from the biophysical alterations of skin structure by ultrasound waves. The frequency used for phonophoresis is usually from 20 kHz to 15MHz. Phonophoresis can be categorized in to three ranges: low-frequency range(below 1 MHz). therapeutic frequency range(1 to 3MHz), and high-frequency range(above 3 MHz). The depth of penetration of ultrasound into skin is inversely proportional to the frequency. Cavitation may cause mechanical stress. temperature elevation, or enhanced chemical reactivity causing drug transport. One theory is that ultrasound affects the permeation of the stratum corneum lipid structure as the limiting step in permeating through the skin. The range of indications for phonophoresis is wide. Aspecific classification of the range of indications is obtained by classification of pathological conditions. The continuous research is needed for many interesting issucs of phonophoretic transdermal delivory in new future.

  • The purposes of this paper is to study the characteristics of compared to the speakers voice without depression and speakers with depression, and to propose a objective method for the measurement of the therapeutic effects as well as for diagnostics of depression based on the characteristics. The voice samples obtained from 11 female speakers with depression, aged from 20 to 40, diagnosed as having major depressive disorder by an psychiatrist were compared with those from 12 normal controls with matched sex, age, height, weight, education, smoking, and drinking. The voice samples are taken by a portable digital recorder(TASCAM DR-07, Japan) and analysed using the MDVP(Multi-Dimentional Voice Program) software module from CSL(Computerized Speech Lab, kay elemetrics, co, model 4100). The result of the investigation are as following. First, the average speaking fundamental frequency and loudness range of the speakers with depression group was statistically significantly lower than that of the control group. The pitch range of the control group was rather higher than that of the speakers with depression group, but without statistical significance. Overall speech rates have no statistical difference between two groups. Second, the average speaking fundamental frequency and loudness range have statistically significant negative correlation with Beck Depression Inventory, i. e. more severe depression exhibits lower average speaking fundamental frequency and loudness range. Other vocal parameters such as pitch range and overall speech rate have no statistically meaningful correlations with Beck Depression Inventory.

  • This experiment was conducted to find out the therapeutic effect of Artemisia capillaris extracts on hepatic damage in rats induced by carbon tetrachloride ($CCl_{4}$). In this experiment, 96 Sprague-Dawley rats were used as experimental groups, which were divided into 4 groups; control group(A), $CCl_{4}$-treated group(B), $CCl_{4}$+Artemisia extract-treated group(C) and $CCl_{4}$+silymarin-treated group(D). The B, C, D group were administrated single dose of $CCl_{4}$(2.5 ml/kg) to induce acute hepatic injury. C group was administrated with Artemisia capillaris extract(200 mg/kg/day) and D group treated with silymarin(50 mg/kg/day) for 7 days. Hematological, ultrasonographical, histological examinations and examination of antioxidant activity were also performed in all groups. AST and ALT activities of C group were significantly decreased compared with B group. The activities of AST and ALT in C and D groups returned to the normal range more rapidly than those of B group. In ultrasonographic examination, the echogenicity of liver in C group was significantly decreased compared with B group. Also C and D group had tended to recover faster than B group on liver histogram. Histologically, the percentage of degenerative regions and degenerative cell numbers in peri-central vein hepatic parenchyma of C and D group were significantly decreased compared with B group. In examination of lipid peroxidation, malondialdehyde of hepatic tissue in C group was decreased as compared with B group. In examination of antioxidant enzyme activity in liver, glutathione peroxidase and catalase activities were significantly increased compared with B group. As results of this study, it is thought that A. capillaris extract has therapeutic effects on hepatic injury induced by carbon tetrachloride, and has the similar therapeutic effects as silymarin in rats.

  • People with spinocerebellar ataxia, a hereditary and progressive neurogenic disorder, suffer from ataxic dysarthria due to cerebellar dystrophy. This study was designed to examine if intensive motor speech treatment yields improvement in progressive ataxic dysarthria and if then, to investigate magnitude of therapeutic effect. SPEAK $OUT!^{(R)}$ was provided to a 55-year old female diagnosed with SCA for improving motor speech functions. Magnitude of therapeutic effect was large in changes of MPT and vocal intensity across speech tasks. Small effect size was found in changes of fundamental frequency, however, large therapeutic effect was observed in changes of frequency range. In addition, improvement of vocal quality based on jitter, shimmer, and HNR was observed with large therapeutic effect size and vowel space was expanded, particularly, due to F1. Lastly, VHI scores were decreased. Intensive motor speech treatment, called as SPEAK $OUT!^{(R)}$ was effective enough to observe improvement in vocal intensity, frequency range, and vocal quality, expanding vowel space and lowering VHI scores. Based on the results of this case study, further efficacy evaluation of SPEAK $OUT!^{(R)}$ for improving progressive ataxic dysarthria in people with SCA is required.

  • Cyclosporine (CsA) has become well established as a potent immunosuppressive agent in the renal transplantation. However, therapy is complicated by large intraindividual and interindividual variability in pharmacokinetics of CsA and frequent undesirable clinical outcomes such as graft rejection and nephrotoxicity. The objective of this study was to determine the CsA trough blood concentrations that were associated with acute graft rejection and renal toxicity in renal transplant patients. Also, the ability of the current recommendation of therapeutic range for CsA to prevent graft rejections and CsA-associated renal toxicity was assessed. The clinical courses of the patients on CsA as an immusuppressive agent for preventing the graft rejection with renal ransplantation performed at Seoul National University Hospital from January 1995 to September 1998 were retrospectively reviewed. Total of 78 patients were included and three of them were retransplantation cases. Twenty-two acute episodes of rejection were identified, but only 16 episodes were clinically significant. Of these all the episodes occurred during the first month after transplantation except one. Mean daily doses of CsA were $427.2\pm72.1,\;352.6\pm56.8,\;308.62\pm48.3\;and\;268.47.1\;mg$ at posttransplant 1, 3, 6, and 12 months, respectively. Mean CsA whole blood though levels were $259.8\pm36.2,\;238.5\pm39,\;200.8\pm45.8\;and\;161.9\pm25.8\;ng/ml$ at posttransplant 1, 3, 6 and 12 months, respectively. Mean daily doses/weight were $7.9\pm1,\;6.4\pm1,\;5.3\pm0.7\;and\;4.6\pm0.7\;mg/kg$ at posttransplant 1, 3, 6 and 12 months, respectively. CsA doses decreased significantly as months progressed (p<0.001). During the first month after transplantation, only $12.5\%$ of the patients in rejection group had CsA concentration in therapeutic range, and 87.5, 93.8, and $100\%$ were within the therapeutic range at posttransplant 3, 6, and 12 months, respectively. These results suggested that CsA concentrations of $250\sim300\;ng/ml$ might be appropriate for preventing the acute rejection during the first posttransplant month.

  • Purpose: To estimate the viral suppressive effect of entecavir monotherapy in Korean children and adolescents with lamivudine-resistant chronic hepatitis B (CHB). Methods: One milligram of entecavir was administered once daily to 6 patients (4 boys; mean age, 17.5 years; range, 15.10~24.6 years) with lamivudine-resistant CHB for a mean duration of therapy of 13.4 months (range, 1~21.1 months). The therapeutic results were compared with 11 patients who received adefovir (0.3 mg/kg/day [maximal dose 10 mg]) for at least 12 months (mean, 33.4 months; range, 12.4~58.3 months). The serum HBV DNA level and serologic markers were measured every 2 months. Results: The interval to a HBV DNA titer decrement (>1 $log_{10}$) was 1.2${\pm}$0.2 and 4.4${\pm}$5.2 months (p=0.185) for the entecavir and adefovir groups, respectively. The interval to a HBV DNA titer decrement (>2 $log_{10}$) was 2.4${\pm}$2.3 and 9.2${\pm}$7.3 months (p=0.025), for the entecavir and adefovir groups, respectively. Conclusion: The therapeutic efficacy of entecavir was favorable in children and adolescents, especially in shortening the interval to a >2 $log_{10}$ decrement in the HBV DNA titer. Long-term follow up is needed to determine the therapeutic efficacy of entecavir for lamivudine-resistant CHB in children and adolescents.

  • In the treatment of mandibular condylar fractures, arthrocentesis, lavage and selective intermaxillary fixation were performed after closed reduction. In this lavage group, the physiotherapy performed for 3-6 months after injury. in control group, continuous intermaxillary fixation was done for 1-3 weeks, and physiotherapy followed in the same method of the lavage group. In the comparative study of the both groups, the following results are shown. 1. Compared to control group, the lavage group had a slightly superior result at range of motion, joint pain and occlusal deviation, from I day after arthrocentesis to 6 months after injury. 2. The significant differences between both groups were seen at range of motion and joint pain in 1 month after injury. 3. At 6 months after injury, the differences between both groups were not significant at range of motion, joint pain and occlusal deviation. From this study, in the mandibular condylar fracture, the arthrosentesis, lavage and selective intermaxillary fixation after closed reduction can improve symptoms such as joint pain and occlusal deviation, also increase range of motion. in this therapeutic way, intracapsular hemarthrosis which can cause TMJ ankylosis or dysfunction can be removed effectively. in addition, patient's discomfort such as swallowing disturbance, speech disturbance and emotional stress can be reduced signuficantly.

  • The purpose of this study is to evaluate pain and range of motion in the frozen shoulder and to compare Hold-Relax technique with ROM exercise. Twenty-eight frozen shoulder patients between 41 nod 76 years of age were selected and were divided equally by random distribution into a Hold-Relax technique group and a ROM exercise group. To analyze the therapeutic effect between the two groups, two measurements were taken. A measurement of pain was taken by visual analogue scale and a measurement of range of motion was taken by measuring flexion and abduction degrees with a goniometer. The results were as followings : 1. The Hold-Relax group is more effective in decreasing the pain than the ROM exercise group. 2. The Hold-Relax group is more effective in increasing the range of flexion at the shoulder than the ROM exercise group. 3. The Hold-Relax group is more effective in increasing the range of abduction at the shoulder than the ROM exercise group.
