Clinical history and dermatological examinations were performed in 51 patients with contact dermatitis due to metal working fluid who were working at the metal industry. Patch tests were also performed with standard series and oil cooling fluid series. Chronic lichenified eczema such as lichenified and fissured was the most common clinical type(45.1%). 19 patients had positive reaction to either one or more of the standard series and oil & cooling fluid series. We found ammoniated mercury chloride was the most common sensitizer in standard series, followed by potassium dichromate, 4-phenylendiamine dihydrochloride, cobalt chloride, nickel sulfate, quinoline mix and cabra mix. Microbiocide was the most common allergen(4 of 6 positive result in oil & cooling fluid series.

3.Voluntary Wheel Running Exercise Improves Aging-Induced Sarcopenia via Activation of Peroxisome Proliferator-Activated Receptor Gamma Coactivator-1α/Fibronectin Type III Domain-Containing Protein 5/Adenosine Monophosphate-Activated Protein Kinase Signaling Pathway
International Neurourology Journal 2021;25(Suppl 1):S27-34
Purpose:
In this study, the protective effect of voluntary wheel running exercise on muscle loss and muscle weakness in gastrocnemius of old rats was investigated. The association of voluntary wheel exercise with the peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α)/fibronectin type III domain-containing protein 5 (FNDC5)/adenosine monophosphate- activated protein kinase (AMPK) signaling pathway and vascular endothelial growth factor (VEGF) expression was also evaluated.
Methods:
Six-month-old and 22-month-old male rats were used for this experiment. The rats in voluntary wheel running exercise groups were performed wheel running for 2 months. Weight bearing test for walking strength, rotarod test for motor coordination and balance, hematoxylin and eosin (H&E) staining for histological changes in the muscle tissues, Western blot analysis for PGC-1α, FNDC5, AMPK, immunofluorescence for VEGF were conducted.
Results:
Decreased muscle mass, strength, and coordination due to aging were associated with a decrease in the PGC-1α/ FNDC5/AMPK signaling pathway in the gastrocnemius. Voluntary wheel running exercise enhanced VEGF expression by activating the PGC-1α/FNDC5/AMPK signaling pathway, then increased muscle mass, strength, and coordination.
Conclusions
It has been suggested that voluntary wheel running exercise alleviates symptoms of urological diseases that are difficult to treat. Wheel running exercise is a good therapeutic strategy to prevent or treat aging-related sarcopenia.

5.Voluntary Wheel Running Improves Spatial Learning Memory by Suppressing Inflammation and Apoptosis via Inactivation of Nuclear Factor Kappa B in Brain Inflammation Rats
International Neurourology Journal 2020;24(Suppl 2):96-103
Purpose:
Exercise has been shown to protect against diverse brain diseases. Voluntary exercise improves cognition and has a neuroprotective effect. The aim of this investigation is to study the effect of voluntary wheel running on brain inflammation in rats with regard to inflammation and apoptosis.
Methods:
Brain inflammation was caused by intracranial injection of lipopolysaccharide using a stereotaxic instrument. Voluntary wheel running group were conducted during 21 consecutive days, staring 2 days after brain inflammation.
Results:
Brain inflammation increased proinflammatory cytokine production and apoptosis cell death in the hippocampus. There changes in the hippocampus deteriorated spatial learning memory. However, voluntary wheel running suppressed the secretion of inflammatory cytokines and apoptotic neuronal cell death via inactivation of nuclear factor kappa B (NF-κB)/NF-κB inhibitor-α pathway. Voluntary wheel running also promoted the recovery of the spatial learning memory impairment.
Conclusions
Voluntary wheel running after brain inflammation enhanced spatial learning memory by suppressing proinflammatory cytokine secretion and apoptosis cell death. Voluntary wheel running is also expected to be effective in inflammatory diseases of the urogenital system.

PURPOSE: To compare clinical outcomes of the tumor prosthetic replacement and osteosynthetic fixation for pathologic fracture of skeletal metastatic lesion of the proximal femur. MATERIALS AND METHODS: From 1994 May to 2009 May, medical records of 22 patients who underwent tumor prosthetic replacement with tumor resection (group 1) and 15 others (16 hips) who underwent osteosynthetic fixation without tumor resection (group 2) were reviewed. The mean age of overall patients were 59 (group 1) and 60 (group 2). Mean follow up periods were 23 and 11 months. The oncological and functional results were evaluated with Kaplan-Meier methods and Musculoskeletal Tumor Society (MSTS) scoring system, 1993. The statistical evaluation was assessed with Log rank test and t-test. RESULTS: The mean survival periods were 24 months in group 1 and 11months in group 2. The 1 year survival rates were 86% in group 1 and 50 % in group 2, and 2 year survival rates were 29.7% in group 1 and 9.4% in group 2. The mean MSTS functional score were 26.4 (19-30), 87.9% in group 1 and 15.3 (10-23), 51.0% in group 2. CONCLUSION: The results of tumor resection and prosthetic replacement in selected cases was better than osteosynthetic fixation without tumor resection for metastatic bone tumors around proximal femur in oncological and functional aspects.

PURPOSE: Surface alterations of titanium discs following instrumentation with either a nylon brush or a metal brush were evaluated. METHODS: A total of 27 titanium discs with 3 surface types (9 discs for each type), including machined (M) surfaces, sandblasted and acid-etched (SA) surfaces, and surfaces treated by resorbable blast media (RBM), were used. Three discs were instrumented with a nylon brush, another 3 discs were instrumented with a metal brush, and the remaining 3 discs were used as controls for each surface type. Surface properties including the arithmetic mean value of a linear profile (Ra), maximum height of a linear profile (Rz), skewness of the assessed linear profile (Rsk), arithmetic mean height of a surface (Sa), maximum height of a surface (Sz), developed interfacial area ratio (Sdr), skewness of a surface profile (Ssk), and kurtosis of a surface profile (Sku) were measured using confocal microscopy. RESULTS: Instrumentation with the nylon brush increased the Ra, Sa, and Sdr of the M surfaces. On the SA surfaces, Ra, Sa and Sdr decreased after nylon brush use. Meanwhile, the roughness of the RBM surface was not affected by the nylon brush. The use of the metal brush also increased the Ra, Sa, and Sdr of the M surface; however, the increase in Sdr was not statistically significant (P=0.119). The decreases in the Rz, Sz, Ra, Sa, and Sdr of the SA surfaces were remarkable. On the RBM surfaces, the use of the metal brush did not cause changes in Ra and Sa, whereas Rz, Sz, and Sdr were reduced. CONCLUSIONS: Titanium surfaces were altered when instrumented either with a nylon brush or a metal brush. Hence, it is recommended that nylon or metal brushes be used with caution in order to avoid damaging the implant fixture/abutment surface.

We studied 30 patients who participated in accelerated rehabilitation program after ACL reconstruction to evaluate the effects on knee joint function prospectively. This program emphasizes early full hyperextension, early weight bearing as tolerated, and closed-chain quadriceps functional activities with rapid return to sports. Timing of the return to occupation, activity level, manual knee test, range of motion, thigh circumference, Lysholm knee score and KT-2000 arthrometer measurement were checked at the latest follow-up which is at least more than 1 year. The result were as follows: 1. The mean time for patients to return to occupation was 7.5 weeks (2 weeks-6 months). 2. Range of motion of the knee were not limited in 25 cases (83%) at 1 year after reconstruction. 3. The mean Lysholm score was 92.7. 4. The mean manual maximum KT-2000 arthrometer score was 2.0mm. The results of this study show that patients who had an ACL reconstruction with an autogenous central 1/3 patellar tendon graft and followed an accelerated rehabilitation program obtained longterm stability, achieved full range of motion, had a low complication rate, and were able to return to full sporting activities predictably.
