PURPOSE: The purpose of this study was to investigate the effects of kinesio taping on lumbar flexibility onto erector spinae and sacroiliac joint. METHODS: Sixty healthy adults (male=36, female=24) participated in this study and were randomly assigned to the experimental group that received kinesio taping onto erector spinae and sacroiliac joint (n=30) or the control group that received X-letter placebo taping onto them (n=30). Lumbar flexibility (flexion, extension, lateral flexion, and rotation) was measured using back range-of-motion instrument (BROM) II before and after taping. RESULTS: In the change of lumbar flexibility after taping in the experimental group, there were statistically significant difference in flexion, lateral flexion, and rotation (p < 0.05), but there was no significant difference in extension. There was no significant difference in the change of lumbar flexibility after taping in the control group. CONCLUSION: In conclusion, kinesio taping onto erector spinae and sacroiliac joint improved the joint function. Kinesio taping may reduce the muscle tension and facilitate the circulation of tissue fluid. In light of these results, it is thought that the application of kinesio taping had influence on an increase in lumbar flexibility. Therefore, kinesio taping will be able to be used as the method of the prevention of pain and the treatment in the lumbar region.

Background: and Purpose: Ventricle enlargement has been implicated in the pathophysiology of Alzheimer’s disease (AD). We studied the relationship between ventricular size and cognitive function in patients with AD. We focused on the effect of the initial ventricle size on the rate of cognitive decline in patients with AD. Methods: A retrospective analysis of probable clinical AD participants with more than 2 magnetic resonance imaging images was performed. To measure ventricle size, we used visual rating scales of (1) Cardiovascular Health Study (CHS) score and (2) conventional linear measurement method. Results: Increased clinical dementia rating (CDR) was correlated with a decreased MiniMental Status Examination (MMSE) score, and increased medial temporal lobe atrophy (MTLA) and global ventricle size (p<0.001, p<0.001, p=0.021, respectively). There was a significant correlation between the change in cognitive function in the group (70%–100%ile) with a large initial ventricle size (p=0.021 for ΔCDR, p=0.01 for ΔMMSE), while the median ventricle size (30%–70%ile) showed correlation with other brain structural changes (MTLA, frontal atrophy [FA], and white matter) (p=0.036 for initial MTLA, p=0.034 for FA). Conclusions In this study, the initial ventricle size may be a potential new imaging biomarker for initial cognitive function and clinical progression in AD. We found a relationship between the initial ventricle size and initial AD-related brain structural biomarkers.

BACKGROUND: Nefopam has been known as an inhibitor of the reuptake of monoamines, and the noradrenergic and/or serotonergic system has been focused on as a mechanism of its analgesic action. Here we investigated the role of the spinal dopaminergic neurotransmission in the antinociceptive effect of nefopam administered intravenously or intrathecally. METHODS: The effects of intravenously and intrathecally administered nefopam were examined using the rat formalin test. Then we performed a microdialysis study to confirm the change of extracellular dopamine concentration in the spinal dorsal horn by nefopam. To determine whether the changes of dopamine level are associated with the nefopam analgesia, its mechanism was investigated pharmacologically via pretreatment with sulpiride, a dopaminergic D2 receptor antagonist. RESULTS: When nefopam was administered intravenously the flinching responses in phase I of the formalin test were decreased, but not those in phase II of the formalin test were decreased. Intrathecally injected nefopam reduced the flinching responses in both phases of the formalin test in a dose dependent manner. Microdialysis study revealed a significant increase of the level of dopamine in the spinal cord by intrathecally administered nefopam (about 3.8 fold the baseline value) but not by that administered intravenously. The analgesic effects of intrathecally injected nefopam were not affected by pretreatment with sulpiride, and neither were those of the intravenous nefopam. CONCLUSIONS: Both the intravenously and intrathecally administered nefopam effectively relieved inflammatory pain in rats. Nefopam may act as an inhibitor of dopamine reuptake when delivered into the spinal cord. However, the analgesic mechanism of nefopam may not involve the dopaminergic transmission at the spinal level.

Development of a therapy providing protection from, or reversing gentamicin-sulfate (GS)-induced oxidative stress and nephrotoxicity would be of great clinical significance. The present study was designed to investigate the protective effects of Houttuynia cordata Thunb. (HC) against gentamicin sulfate-induced renal damage in rats. Twenty-eight Sprague-Dawley rats were divided into 4 equal groups as follows: group 1, control; group 2, GS 100 mg/kg/d, intraperitoneal (i.p.) injection; group 3, GS 100 mg/kg/d, i.p. + HC 500 mg/kg/d, oral; and group 4, GS 100 mg/kg/d i.p. + HC 1000 mg/kg/d, oral administration). Treatments were administered once daily for 12 d. After 12 d, biochemical and histopathological analyses were conducted to evaluate oxidative stress and renal nephrotoxicity. Serum levels of creatinine, malondialdehyde (MDA), and blood urea nitrogen (BUN), together with renal levels of MDA, glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) were quantified to evaluate antioxidant activity. Animals treated with GS alone showed a significant increase in serum levels of creatinine, BUN, and MDA, with decreased renal levels of GSH, SOD, and CAT. Treatment of rats with HC showed significant improvement in renal function, presumably as a result of decreased biochemical indices and oxidative stress parameters associated with GS-induced nephrotoxicity. Histopathological examination of the rat kidneys confirmed these observations. Therefore, the novel natural antioxidant HC may protect against GS-induced nephrotoxicity and oxidative stress in rats.

PURPOSE: In humans, nineteen types of WNT genes (WNTs) have been hightlighted up to date. The canonical Wnt cascade has recently emerged as a critical regulator of stem cells. To obtain new insights how nineteen WNTs affect mesenchymal stem cells differentiation, we analyzed the transcriptional activity, osteogenic and adipogenic activity of WNTs in mesenchymal stem cells. MATERIALS AND METHODS: Recombinant adenoviruses expressing nineteen WNTs were constructed to infect pluripotent mesenchymal progenitor C3H10T1/2 cells. Transcriptional activity was determined by using the luciferase reporter assay. Osteogenic activity was determined by measuring the induction of alkaline phosphatase upon Wnt stimulation. Adipogenic activity was measured by histochemical Oil red-O staining. RESULTS: WNT1, 2, 3, 3A and 10B significantly induced transcriptional activity in C3H10T1/2 cells. WNT1, 2, 3, 3A and 10B significantly induced alkaline phosphatase activity, but inhibited adipogenic activity in C3H10T1/2 cells. The results of qualitative and quantitative assay of alkaline phosphatase activity were consistent with those of luciferase assay for transcriptional activity and Oil red-O staining for adipogenic activity. CONCLUSION: We could expect that WNT1, 2, 3, 3A and 10B may play a crucial role in inducing osteoblast differentiation of mesenchymal stem cells.

BACKGROUND: CDX1 and CDX2, members of the caudal-type homeobox gene family, control proliferation and differentiation of intestinal mucosal cells. Their expression is reduced commonly in colorectal cancers, but reports about the relationship between their expression and the clinicopathologic features are rare. The aim of this study was to examine CDX1 mRNA and CDX2 mRNA expression in colorectal cancers and to assess the relationship between their expression and the clinicopathologic features. METHODS: CDX1 mRNA and CDX2 mRNA expression were analyzed by real-time polymerase chain reaction in 48 colorectal cancers and their adjacent non-tumorous normal mucosas. RESULTS: CDX1 mRNA and CDX2 mRNA expression were decreased significantly in colorectal cancers than in normal mucosas (p=0.001, p=0.042, respectively). In comparison with paired normal mucosas, colorectal cancers showed decreased CDX1 mRNA expression in 64.6% (31/48) and decreased CDX2 mRNA expression in 66.7% (32/48). There was a statistically significant correlation between CDX1 mRNA and CDX2 mRNA expression in colorectal cancers (r=0.543, p<0.001). CDX1 mRNA and CDX2 mRNA expression were not related to age, sex, location of cancer, differentiation, lymphatic or vascular invasion, lymph node metastasis, stage and serum carcinoembryonic antigen level in colorectal cancers. CONCLUSION: CDX1 mRNA and CDX2 mRNA expression were decreased significantly in colorectal cancers, but were not related to the clininopathologic features.

BACKGROUND: CDX1 and CDX2 are members of the caudal-type homeobox gene family and control the proliferation and differentiation of intestinal mucosal cells. Their expressions are commonly reduced in colorectal cancer, but reports about the relationships between their expressions and clinicopathologic features are rare. The aim of this study was to examine the expressions of CDX1 and CDX2 mRNAs in colorectal cancers and to assess the relationships between their expressions and clinicopathologic features. METHODS: CDX1 and CDX2 mRNA expressions were analyzed by real-time polymerase chain reaction in 48 colorectal cancers and in adjacent non-tumorous normal mucosal tissue. RESULTS: CDX1 and CDX2 mRNA expressions were significantly reduced in colorectal cancer tissues versus normal mucosal tissues (p=0.001, p=0.042, respectively). As compared with paired normal mucosal tissues, colorectal tissues showed reduced CDX1 mRNA expression in 64.6% (31/48) and reduced CDX2 mRNA expression in 66.7% (32/48) of cases. A statistically significant positive correlation was found between the expressions of CDX1 mRNA and CDX2 mRNA in colorectal cancer (r=0.543, p< 0.001). However, the expressions of CDX1 and CDX2 mRNAs were not related to age, sex, cancer location, differentiation, lymphatic or vascular invasion, lymph node metastasis, stage or serum carcinoembryonic antigen level. CONCLUSIONS: CDX1 and CDX2 mRNA expressions were found to be significantly reduced in colorectal cancers, but these expressional changes were not found to be related to clinicopathologic features.

Arteriovenous malformation (AVM) of the pancreas is an extremely rare disease. It may be asymptomatic, but more than half of the patients present with gastrointestinal bleeding. The most common cause of the gastrointestinal bleeding is variceal bleeding due to the portal hypertension resulting from AVM. Bleeding from a duodenal ulcer and AVM to the pancreatic duct are rare findings. Surgical excision is the treatment of choice, but when portal hypertension has developed, this cannot be corrected even after surgical resection. We experienced a case of recurrent duodenal ulcer bleeding that was due to arteriovenous malformation in the head of the pancreas in a 45 year old man. He was successfully treated with pylorus preserving pancreaticoduodenectomy.

PURPOSE: The implementation of the Korean diagnosis-related groups (DRG) payment system has been recently introduced in selected several diseases including appendectomy in Korea. Here, we report the early outcomes with regard to clinical aspects and medical costs of the Korean DRG system for appendectomies in Seoul Metropolitan Government - Seoul National University Boramae Medical Center throughout comparing before and after introduction of DRG system. METHODS: The DRG system was applied since January 2013 at our institute. After the DRG system, we strategically designed and applied our algorithm for the treatment of probable appendicitis. We reviewed the patients who were treated with a procedure of appendectomy for probable appendicitis between July 2012 and June 2013, divided two groups based on before and after the application of DRG system, and compared clinical outcomes and medical costs. RESULTS: Total 416 patients were included (204 patients vs. 212 patients in the group before vs. after DRG). Shorter hospital stays (2.98 +/- 1.77 days vs. 3.82 +/- 1.84 days, P < 0.001) were found in the group after DRG. Otherwise, there were no significant differences in the perioperative outcomes and medical costs including costs for first hospitalization and operation, costs for follow-up after discharge, frequency of visits of out-patient's clinic or Emergency Department or rehospitalization. CONCLUSION: In the Korean DRG system for appendectomy, there were no significant differences in perioperative outcomes and medical costs, except shorter hospital stay. Further studies should be continued to evaluate the current Korean DRG system for appendectomy and further modifications and supplementations are needed in the future.

This study was performed to evaluate the efficacy and toxicity of low-dose paclitaxel/cisplatin chemotherapy in patients with metastatic or recurrent gastric cancer that had failed 5-fluorouracil/platinum-based chemotherapy. Thirty-two patients with documented progression on or within 6 months after discontinuing 5-fluorouracil/platinum-based chemotherapy were enrolled. As a second-line treatment, paclitaxel (145 mg/m2) and cisplatin (60 mg/m2) was administered on day 1 every 3 weeks. Among 32 patients enrolled, 8 (25%) responded partially to paclitaxel/cisplatin, 8 (25%) had stable disease, and 14 (44%) had progressive disease. Two patients (6%) were not evaluable. The median time to progression (TTP) and overall survival for all patients were 2.9 months and 9.1 months, respectively. The most common hematologic toxicity was anemia (47%). Grade 3 neutropenia developed in three patients (9%), but no other grade 3/4 hematologic toxicity occurred. The most common non-hematologic toxicities were emesis (31%) and peripheral neuropathy (38%). Three cases (9%) of grade 3/4 emesis and 2 cases (6%) of grade 3 peripheral neuropathy developed. In conclusion, low-dose paclitaxel and cisplatin chemotherapy showed moderate activity with favorable toxicity profiles. However, relatively short TTP of this regimen warrants the development of more effective paclitaxel-based regimens other than combination with cisplatin in these patients as second-line therapies.
