2.The Effects of Curl-up Exercise with XCO on Trunk Muscle Activation in Healthy Adults
Journal of Korean Physical Therapy 2020;32(4):210-216
Purpose:
This study examined the effects of curl-up using XCO® on trunk muscle activation in healthy adults.
Methods:
This study design was a single-blind randomized controlled trial. Twelve participants were enrolled in this study. The subjects were instructed to perform curl-up exercise in STCU (straight curl-up), LTCU (left twist curl-up), RTCU (right twist curl-up), TWCU (twist curl-up), and PPCU (power push curl-up). Electromyography was used to assess the percent maximal voluntary isometric contraction (%MVIC) of the rectus abdominis (RA), external oblique (EO), internal oblique (IO), and erector spinae (ES) muscles. The data were analyzed using two-way ANOVA with a repeated measure. The statistical significance level was set to α=0.05
Results:
The IO showed significant differences in the main effect of the group and the interactions between the group and exercise (p<0.05). In particular, the IO represented the interactions between group and exercise in the RTCU and PPCU (p<0.05). The RA, EO, and ES did not show significant interactions between the group and exercise (p>0.05). The RA, IO, and EO showed significant differences in the main effect of the group (p<0.05). The EO showed a significant difference in the main effect of exercise (p<0.05).
Conclusion
These findings suggest that XCO® can be used to increase the muscle activation of the internal oblique, which is the lumbar stabilizing muscle, when XCO® is combined in the curl-up exercise with rotation. In the future, research on the intensity, frequency, and duration of XCO® exercise will be needed according to the individual characteristics and preferences.

PURPOSE: Entering a new century in the year 2001, Chungbuk National University Medical School (CNUMS) decided to adopt a fully integrative curriculum. This plan has been executed from 2002 to 2005. we are now at a point to assess this new curriculum and further improve it for the future. METHODS: We studied 'Curricula for Undergraduate' from Chungbuk National University and 'The Present Educational Status of Medical College' the Dean's Council of Korean Medical College published from 1987 to 2005. RESULTS: All lectures consisted of integrated lectures between the basic and clinical medical sciences. First and second year lectures focused on the horizontal integration of basic and clinical medical sciences, respectively. Also lectures between the first and second years formed longitudinal integration and purposeful repetition. Practical Classes were comprised of essential major clinical medicines and elective clinical medicines. Generally, lectures were reduced to introduce active learning subjects including problem-based learning (PBL), communicational skills, objective structured clinical examination (OSCE) /clinical performance examination (CPX), basic clinical skills, community medicine, and health and society. CONCLUSION: The curriculum of CNUMS was changed from the traditional department-centered lectures to integrated organ-centered integrated lectures and practical classes. However, further innovation is required on the inside of curriculum.

Pathophysiological conditions such as sepsis and hepatitis are frequently associated with cholestasis. Cholestasis in patients with sepsis has been attributed to the effects of endotoxin(lipopholysaccharides, LPS) and LPS-induced cytokines(TNF-a, IL-6, IL-1, etc.). LPS and cytokines reduced bile acid uptake in cultured hepatocyte. Perfusion of LPS decrease the bile flow in the isolated liver. Bile flow is increased by intravenous infusion of secretin, but it's effect remains unclear in sepsis. The aim, of this study is to elucidate the effect of LPS on the bile flow and bile composition and to test the effect of secretin on the bile flow. The animals used in this study were Korean wild cats. Under the general anesthesia, the incision was made on the midline. Common bile duct was cannulated with polyethylene tube after cholecystectomy. Bile was collected every five minutes and its volume was measured. E. coli LPS(1 mg/kg), secretin(0.1mg/kg) and H3-taurocholic acid(0.2uCi/kg) were infused via mesenteric vein. Bile was collected every 5 minutes, and the volume and its composition were analyzed. Radio-activity of the bile was quantified by Packard 1600 TR liquid scintillation analyzer. LPS of E.coli (1mg/kg) had a little effect on the blood pressure. LPS decreased the bile flow by 37% compared with the control group. Maximal impairment of the bile secretion appeared 15 minites after LPS infusion, and then secreted stablely thereafter. Secretin increased the bile flow in the normal control group. It, however, did not make any change in the bile flow after LPS infusion. LPS also reduced H3-taurocholate secretion(maximum 56%), and peak level was delayed about 10 minites compared with control group. In the composition of the bile, LPS decreased the secretion of bile acids significantly compared with the control group. Conclusively, LPS decreased the bile flow and the bile acid secretion. Secretin did not stimulate the bile flow in the LPS group. It also reduced the bile acids secretion compared with the control group. These findings will contribute to the understanding and treatment of the cholestasis and impairment of the liver function of sepsis. The findings, of reduced bile acids secretion in the LPS group may explain the pathogenesis of intrahepatic gallstone partly.

PURPOSE: It is important to differentiate malignant from benign lesions of intraocular masses in choosing therapeutic plan. Biopsy of intraocular tumor is not recommended due to the risk of visual damage. We evaluated the usefulness of F-18-FDG PET imaging in diagnosing intraocular neoplasms. MATERIALS AND METHODS: F-l8-FDG PET scan was performed in 13 patients (15 lesions) suspected to have malignant intraocular tumors. There were 3 benign lesions (retinal detachment, choroidal effusion and hemorrhage) and 10 patients with 12 malignant lesions (3 melanomas, 7 retinoblastomas and 2 metastatic cancers). Regional eye images (256*256 and 128*128 matrices) were obtained with or without attenuation correction. Whole body scan was also performed in eight patients (3 benign and 6 malignant lesions). RESULTS: All malignant lesions were visualized while all benign lesions were not visualized. The mean peak standardized uptake value (SUV) of malignant lesions was 2.64+/-0.57 g/ml. There was no correlations between peak SUV and tumor volume. Two large malignant lesions (>1000 mm3 ) showed hot uptake on whole body scan. But two medium-sized lesions (100-l000 mm3) looked faint and two small (<100 mm3) lesions were not visualized. The images reconstructed with 256*256 matrix showed lesions more clearly than those with 128X128 matrix. CONCLUSION: F-18-FDG PET scan is highly sensitivity in detecting malignant intraocular tumor. For the evaluation of small-sized intraocular lesions, whole body scan is not appropriate because of low sensitivity. A regional scan with sufficient acquisition time is recommended for that purpose. Image reconstruction in matrix size of 256*256 produced clearer images than the ones in 128X128, but it does not affect the diagnostic sensitivity.

PURPOSE: The measurement of radiation absorbed dose is useful to predict the response after I-131 labeled metaiodobenzylguanidine (MIBG) therapy and determine therapy dose in patients with unresectable or malignant pheochromocytoma. We estimated the absorbed dose in tumor tissue after high dose I-131 MIBG in a patient with pheochromocytoma using a gamma camera and Medical Internal Radiation Dose (MIRD) formula. MATERIALS AND METHODS: A 64-year old female patient with pheochromocytoma who had multiple metastases of mediastinum, right kidney and periaortic lymph nodes, received 74 GBq (200 mCi) of I-131 MIBG. We obtained anterior and posterior images at 0.5, 16, 24, 64 and 145 hours after treatment. Two standard sources of 37 and 74 MBq of I-131 were imaged simultaneously. Cummulated I-131 MIBG uptake in tumor tissue was calculated after the correction of background activity, attenuation, system sensitivity and count loss at a high count rate. RESULTS: The calculated absorbed radiation dose was 32-63 Gy/ 74 GBq, which was lower than the known dose for tumor remission (150-200 Gy). Follow-up studies at 1 month showed minimally reduced tumor size on computed tomography, and mildly reduced I-131 MIBG uptake. CONCLUSION: We estimated radiation absorbed dose after therapeutic I-131 MIBG using a gamma camera and MIRD formula, which can be peformed in a clinical nuclear medicine laboratory. Our RESULTS suggest that the measurement of radiation absorbed dose in I-131 MIBG therapy is feasible as a routine clinical practice that can guide further treatment plan. The accuracy of dose measurement and correlation with clinical outcome should be evaluated further.

PURPOSE: The purpose of this study was to evaluate the diagnostic accuracy of [18F]FDG PET in the diagnosis of recurrent head and neck cancer after the completion of surgery and radiotherapy in patients with head and neck cancers. MATERIALS AND METHODS: In fifty-nine patients with head and neck cancers, whole body [18F]FDG PET studies were performed. According to the different therapeutic modalities, patients were divided into four groups (Group I; pre-treatment, Group II; surgery, Group III; radiotherapy, Group IV; both surgery and radiotherapy). [18F]FDG PET images were compared with clinical, CT and histopathologic findings. RESULTS: For detection of metastatic lymph nodes in 14 patients of pre-treatment group (group I), the sensitivity and specificity of PET were 100% (10/10) and 75% (3/4), and those of CT were 80% (8/10) and 100% (4/4). For detection of recurrence in 45 patients of post-treatment group, overall sensitivity and specificity of PET were 96.2% (25/26) and 78.9% (15/19) [(100% and 75% in group II, 80% and 50% in group III, and 100% and 100% in group IV)] without significant difference from pre-treatment group (p>0.1). In detecting recurrence, the sensitivity and specificity of [18F]FDG PET were 90.9% (10/11) and 20% (1/5) in 16 patients who underwent [18F]FDG PET within 2 months after the completion of treatment. The specificity of these patients was significantly lower than that of 29 patients (100% of sensitivity and specificity) who underwent [18F]FDG PET 2 months after treatment (p<0.05). CONCLUSION: [18F]FDG PET is an accurate diagnostic modality for the detection of recurrence in head and neck cancer. Post-therapy [18F]FDG PET should be obtained at least 2 months after the completion of surgery or radiotherapy.

The purpose of this study is to obtain information of simple and effective methods for the pos-tlaminectomy pain control, and to reduce the consumption of supplemental analgesic drugs and side effects. In a double blind study, 75 patients scheduled for lumbar laminectomy were randomly divided into five groups according to the epidurally instilled drugs, such as, morphine 2mg,Group M2; morphine 3mg,Group M3; methylprednisolone 80 mg, Group D; morphine 2mg plus methylprednisolone 80mg, Group M2D; normal saline as a control Group C. All of the drugs were prepared in 2ml normal saline solution. The following items were recorded in the postoperative period: Pain score using visual analogue scale(VAS) at 6, 12, 24, 48 hours after the operation; the episode of supplemental systemic analgesic; the need for postoperative urethral catheterization; any evidence of respiratory depression; pruritus; nausea and vomiting. The results were as follows. I) VAS score were not significantly different between control group and group M2(p>0.05), but usually less in the group M2 and supplemental analgesic consumption was significantly less in the group M2 than in the control group. 2) VAS score were less in the group M3 than in the group M2 and significantly less than in the control group at 6 hour after operation and also supplemental analgesic consumption was significantly less in the group M3. 3) Group D revealed similar VAS score with group M2 at 6 and 12 hour but significantly lower VAS score at 24 and 48 hour after operation than group M2. 4) VAS score were the most significantly less in the group M2D at 6,12,24,48 hour after operation than in the control group and supplemental analgesic consumption was significantly less in the group M2D. 5) Side effects were not significantly different among all groups. These findings suggest that epidurally instilled morphine 3mg, or methylprednisolone 80mg or both before the closure of the laminectomy wound is effective, simple and safe method for the post-laminectomy pain control and reducing supplemental intramuscular analgesics without specific complication.
