  • The lumbar sympathetic ganglion block (LSGB) is widely used for diagnosing and treating sympathetically maintained pain disorders. The LSGB has been conventionally carried out under fluoroscopy or computed tomography guidance. However, as ultrasound technology improved, ultrasound-guided interventions have been expanding their territory to deeper structures. Ultrasound guidance provides many benefits including protecting vascular injection, shortening procedure time in some cases, and reducing the emission of radiation. In this report, we describe a successful case of a US-guided LSGB without major complications. We expect that US-guided LSGBs can be implemented and furnished in the daily outpatient clinical setting by highly trained pain physicians.

  • The purpose of this study was to analyze oxidized methionines in the myosin isoforms of porcine longissimus thoracis, psoas major, and semimembranosus muscles by liquid chromatography (LC) and mass spectrometry (MS). A total of 836 queries matched to four myosin isoforms (myosin-1, -2, -4, and -7) were analyzed and each myosin isoform was identified by its unique peptides (7.3-13.3). Forty-four peptides were observed from all three muscles. Seventeen peptides were unique to the myosin isoform and the others were common peptides expressed in two or more myosin isoforms. Five were identified as oxidized peptides with one or two methionine sulfoxides with 16 amu of mass modification. Methionines on residues 215 (215), 438 (438), 853 (851), 856 (854), 1071 (1069), and 1106 (1104) of myosin-1 (myosin-4) were oxidized by the addition of oxygen. Myosin-2 had two oxidized methionines on residues 215 and 438. No queries matched to myosin-7 were observed as oxidized peptides. LC-MS/MS allows analysis of the oxidation of specific amino acids on specific residue sites, as well as in specific proteins in the food system.

  • The objective of this study was to determine the influence of quality grade (QG) on meat tenderness characteristics of ten major muscles from Hanwoo steers. A total of 25 Hanwoo carcasses ($5\;carcasses{\times}5\;QGs$) were selected. Intramuscular fat content, collagen content, sarcomere length, and Warner-Bratzler shear force (WBSF) of Longissimus thoracis (LT), Longissimus lumborum (LL), Psoas major (PM), Semisponals (SS), Triceps brachii (TB), Semimembranosus (SM), Gluteus medius (GM), Rectus Abdominis (RA), Superficialis flexor (SF), and Internal and external intercostal (IC) were determined. IC had the highest fat content, followed by LT, RA, LL, PM, GM, SS, SF, TB, and SM. High-fat muscles such as LT, LL, IC, RA, and PM had significantly (p<0.05) different fat contents among QGs. Collagen contents were significantly (p<0.05) different among QGs. With decreasing QG, increasing collagen content was found in muscles. There were significant (p<0.05) differences in sarcomere length among QGs of several muscles. However, no significant (p>0.05) difference in sarcomere length was found among QGs for LL, PM, or RA muscle. PM had the lowest WBSF, followed by LL, LT, RA, IC, GM, SM, SF, SS, and TB. WBSF of QG $1^{{+}{+}}$ was lower than that of QG 1 for SS, TB, and SM. All muscles of QG 1 showed lower WBSF than QG 3 except TB or IC. Results of this study suggested that differences in WBSF among these 10 muscles by QG were due to differences in collagen content and sarcomere length.

  • This study was conducted to measure and analyze the changes in paraspinal muscles of acute and chronic low back pain patients using MRI, and to provide clinical basic data for diagnosis and treatment for low back pain. For this purpose, 20 patients with acute low back pain frome August 2012 to January 2013 which occurred within 12 weeks, and 20 patients with chronic low back pain that progressed over 12 weeks, were chosen as subjects, and their MRI measurements were compared with one another. As a result, in relation to in the fatty degeneration ratio of the left spine and right spine, there were significant differences in erector spinae and multifidus(p<.001), and in relation to the Fat Infiltration ratio between all the groups, there were significant differences in psoas major, erector spinae and multifidus between the acute low back pain patient group and the chronic low back pain patient group(p<.001). In the post-hoc test, multifidus and erector spinae in the acute low back pain group and chronic low back pain group showed the highest Fat Infiltration ratio. The serious Fat Infiltration of multifidus and erector spinae in the chronic low back pain group led to weakened strength of muscles that stabilize the spine. In conclusion, it is considered that this study would present important data and basis in making acute and chronic low back pain patients pay more attention to multifidus and psoas major during rehabilitation exercise, and selecting a rehabilitation exercise program.

  • Six muscles were seamed out randomly from Hanwoo carcasses (n = 12) of each quality grade (quality grades 1, 2 and 3). Samples were analysed for their total and soluble collagen contents, IMCT (intramuscular connective tissue) and Warner-Bratzler shear force (WBSF). Simple correlation (n = 21) was determined for WBSF among major muscles. For LT (longissimus thoracis), total collagen content was significantly higher (p<0.05) for quality grade 3 than those for quality grades 1 and 2. For semitendinosus (ST), semimembranosus (SM), psoas major (PM) and serratus ventralis (SV), total collagen content of quality grade 1 was lowest (p<0.05) of all quality grades. IMCT shear force for gluteus medius (GM) decreased (p<0.05) with better quality grade, and those for other muscles, with the exception of GM, were higher (p<0.05) for quality grade 3 than for quality grades 1 and 2. WBSF values showed GM and LT to be decreased (p<0.05) with better quality grade, and PM to be higher (p<0.05) for quality grade 3 than those for quality grades 1 and 2. SM, ST and SV from quality grade 1 had lower (p<0.05) WBSF value than those from quality grades 2 and 3. Total collagen content of ST was highest (p<0.05) of all muscles, whereas that of PM was lowest (p<0.05). Soluble collagen contents of LT and SV from quality grades 1 and 2 were, in general, higher (p<0.05) than other muscles, but that of SM was lowest (p<0.05). ST and SM had higher (p<0.05) WBSF values for three quality grades when compared to other muscles, whereas PM was lowest (p<0.05). LT had the strongest simple correlation with SV (r = 0.78) and GM (r = 0.77), and SM had the strongest correlation with ST (r = 0.73) and LT (r = 0.73). Also, PM had the strongest correlation with SV (r = 0.62).

  • Purpose: The purpose of this study is to understand the effect of balance and gait when simultaneous application of Kinesio Taping on the lower extremities is done to improve the pattern of hemiplegic patients asymmetric lower extremity. Methods: This study was performed with 7 patients who have hemiplegia symptoms due to stoke. The taping on the paralyzed side was done on tibialis anterior, gluteus medius, gluteus maximus and psoas major and the taping on the unparalyzed side was done on the calf muscle and quadriceps. Berg Balance Scale(BBS) and Time Up and Go Test(TUG) was used to assessment the balance and gait of the patient after the kinesio taping was done on the lower extremities. The results of the test was analyzed by Wilcoxon Signed Rank Test on SPSS(Ver. 10.1). Results: When the taping was done on the paralyzed side, there was a significant improvement of balance and gait in BBS and TUG. When the taping was done on the lower extremities, it showed significant improvement of balance and gait, compared to when the taping was only done on the paralyzed side, according to BBS and TUG. Conclusion: The result of this study shows that the simultaneous taping of the lower extremities of the hemiplegic patients improves balance and gait by improving the pattern of patients lower extremities.
