The reliability of the thickness measurement of the lumbar multifidus (LM) using real-time ultrasonography (US) was determined in only the superficial fiber of the lumbar multifidus (SM). However, previous studies have not examined the reliability of the deep fiber of the LM (DM). The purpose of this study was to determine the intrarater and the interrater reliability of the thickness measurements of DM using US. Eleven healthy males participated in the study. The thickness of the DM was measured with an US in the prone position. Reliability was examined using intraclass correlation coefficients (ICC), standard error of the measurement (SEM), and the Bland and Altman plot. ICC(3,1) was used to calculate the interarater reliability of the thickness measurement of DM using the values from both the first and second test sessions. Additionally, ICC(3,1) was used to calculate the intrarater reliability of the measurements over two days using the measurements obtained in test session 1 and test session 2. The results of this study were as follows: 1) the ICC(3,1) value for interarater reliability was .94 in the first test session, and .93 in the second test session. 2) the ICC(3,1) values for intrarater reliability of the measurements over two days was .90 in both the first examiner and the second examiner The intrarater reliability and interrater reliability of the DM measurements, obtained via the US protocol used in this research was excellent. Therefore, we conclude that the thickness measurement of the DM obtaioned from the US protocol used in this research would be useful for clinician assessment of the thickness of the DM

The lumbrical muscles contribute to the intrinsic plus position, that is simultaneous metacarpophalangeal (MCP) flexion and interphalangeal (IP) extension. The strength of the lumbrical muscles is necessary for normal hand function. However, there is no objective and efficient method of strength measurement for the lumbrical muscles. In addition, previous studies have not investigated the measurement of the cross-sectional area (CSA) of the lumbrical muscles using ultrasonography (US) and the relationship between lumbrical muscle strength in the intrinsic plus position and the CSA. Therefore, the purpose of this study was to identify the measurement method of the CSA of the lumbrical muscles using US and to examine the relationship between maximal isometric strength and the CSA of lumbrical muscles. Nine healthy males participated in this study. Maximal isometric strength of the second, third, and fourth lumbrical muscles was assessed using a tensiometer in the intrinsic plus position which isolated MCP flexion and IP extension. The CSA of the lumbrical muscles was measured with an US. The US probe was applied on the palmar aspect of the metacarpal head with a transverse view of the hand in resting position. There was no significant difference between maximal isometric strength of the lumbrical muscles, but the fourth lumbrical muscle was stronger than the others. The CSA of the lumbrical muscles was significantly different and the fourth lumbrical muscle was significantly larger than the second lumbrical muscle. There was moderate to good correlation between maximal isometric strength and the CSA of the lumbrical muscles. Therefore, we conclude that maximal isometric strength of the lumbrical muscles was positively correlated to the CSA of the lumbrical muscle in each finger, while the measurement of the CSA of the lumbrical muscles, using US protocol in this study, was useful for measuring the CSA of the lumbrical muscles.

The purpose of this study was to compare EMG activity for pectoralis major myscle during shoulder movement with various abduction angle and rotation position in supine position. Fifteen healthy subjects were recruited for this study. All subjects performed shoulder horizontal adduction holding a 2kg dumbbell in shoulder abduction 40°, 70°, 90°, 130°, 160° with shoulder neutral, internal rotation(IR), and external rotation(ER). Surface EMC activity was recorded from pectoralis major clavicle part and pectoralis major sternum part for 5 seconds and EMG activity was normalized to the value of maximal voluntary isometric contraction (%MVIC). Dependent variable were examined with 3 (Neutral, IR, ER) x 5(40°, 70°, 90°, 130°, 160°) analysis of variance with repeated measures. THe EMG activity of pectoralis major muscle was significantly different between shoulder abduction angles and between shoulder rotation positions(p<.05). The highest value of EMG activity of pectoralis major sternum pars among shoulder abduction angles was in 130° and 90° in that order. According to the rotation degree, shoulder ER showed the highest value and IR showed the lowest value in both muscle parts. these results suggest that shoulder abduction 70°, 90°, 130° will be effective during manual muscle testing(MMT) and strengthening exercise for pectoralis major muscle. It is also supposed that shoulder ER is the efficient posture for strengthening of pectoralis major muscle.

N/A Objectives: 80-90% of the cases of hepatocellular carcinoma(HCC) are associated with cirrhosis. Hepatitis B virus(HBV) is known as a major etiologic factor of HCC and about 10% of Koreans are HBV carriers. And the prevalence of HCC is high in Korea. Early detection of HCC is important for the better treatment especially in the patients with cirrhosis who usually have the decreased functional hepatic reserve. Risk factors for the hepatocellular carcinoma in the korean patients with cirrhosis were evaluated. Methods: Risk factors for hepatocellular carcinogenisis such as age, sex, ascites, alcohol, HBsAg, anti-HCV, AFP, ICG R(15) and risk score were investigated among the 176 patients with cirrhosis and HCC(group I) and 72 patients with cirrhosis(group II) and compared between the two groups. Results: 1) No age difference was noted between group I and group II. 2) Male to female sex ratio were 5.7: 1 and 2.4: 1 for group I and II in each(p<0.01) and the frequency of HCC among cirrhosis was higher in male than female sex(p<0.01). 3) Both HBsAg and anti-HCV positivity were significantly higher in group I than in group II (p<0.01 and p<0.05 respectively). 4) The frequencies of Child-Pugh A, elevated AFP, elevated ICG R(15) and the frequency of super-high risk patient were higher in group I than in group II(p<0.01). 5) The frequency of alcoholic patients was significantly higher in group II than in group I (p<0.05) but no difference was noted between HBsAg positive group I and group II patients. 6) The frequency of abnormal AST with the level of below 100IU was not significantly different between group I and group II. 7) The frequency of the patients with ascites was higher in group II than in group I (p<0.01). Conclusion: Risk factors for hepatocellular carcinogenesis in korean patients with cirrhosis are male, Child-Pugh A, HBsAg positivity, anti-HCV positivity, absence of ascites, higher AFP, lower ICG R15 and higher platelet count.

The lumbar multifidus muscle, which can be separated into deep fascicles (DM) and superlicial fascicles (SM), is important for lumbar segmental stability. However, no previous studies have investigated the effect of lumbar stabilization exercises on the thickness of DM and SM. Thus, the purpose of this study was to assess DM thickness after three different lumbar segmental stabilization exercises. In total, 30 healthy male participants were recruited and randomly assigned to one of three exercise groups: hollowing in the quadruped position (H-Quad), contralateral arm and leg lift (CALL), and bilateral arm and leg lift (BALL). Each lumbar segmental stabilization exercise was conducted over 4 weeks. Ultrasonography was used to compare the DM and SM thickness before and after the 4 weeks of exercise. A mixed-model analysis of variance using Scheffe`s post-hoc test was used for statistical analysis. The results showed a significant effect for the measurement time (before vs. after 4 weeks of exercise) in the DM (F=31.26, p<.05) and SM (F=4.56, p<.05). At the end of the 4 weeks, the DM thickness had increased significantly in the H-Quad exercise group, and the SM thickness had increased significantly in the CALL and BALL exercise groups. Also in the BALL exercise group, the SM thickness was greater compared with that in the H-Quad exercise group. These findings suggest that the thickness of the DM and SM were increased by different types of lumbar segmental stability exercise after 4 weeks.

Wild rice might have previously unidentified genes important for disease resistance and stress tolerance in response to biotic and abiotic stresses. A set of subtractive library was constructed both from leaves of wild rice plants, Oryza grandiglumis (CCDD, 2n=48), treated with fungal elicitor and from wounded leaves. A partial fragment that was homologous to PR10 genes from other plant species was identified via suppression subtractive hybridization and cDNA macroarray. The obtained full-length cDNA sequence (OgPR10) contains an open reading frame of 480 bp nucleotide, encoding 160 amino acids with a predicted molecular mass of 16.944 kDa and an isoelectric point (pI) of 4.91. The multiple alignment analyses showed the higher sequence homology of OgPR10 with PR10 genes identified in rice plants at amino acid level. The OgPR10 mRNA was not expressed by treatment with wounding, jasmonic acid, and salicylic acid, but markedly expressed in leaves treated with protein phosphatase inhibitors cantharidin and endothall, and yeast extract. In addition, the expression of OgPR10 mRNA was induced within 72 h after treatment with probenazole, one of well-known chemical elicitors, and reached the highest level at 144 h. Heterologous expression of OgPR10 caused growth inhibition and seedling lethality in E. coli and Arabidopsis, respectively. Chemically induced OgPR10 expression with glucocorticoid-mediated transcriptional induction system further reconfirmed its lethality on Arabidopsis seedling. In addition, OgPR10-expressing rice plants, Oryzae sativar were resistant against the infection of rice blast fungus, Magnaporthe grisea. These results indicate that OgPR10 is involved in probenazole- and microbe associated molecular patterns-mediated disease resistance responses in plants and is a potential gene for developing disease resistance crop plants.

간경변증 환자들은 소화기 증상을 호소하는 경우가 많다. 위내시경 검사상 울혈성 위염이 자주 관찰되어 왔으며 이러한 위장관 증상이 간문맥압 상승으로 인한 위장관 운동기능장애와 연관되어 있을 가능성이 제시되었다. 본 연구에서는 울혈성 위염을 동반한 간경변증 환자에서의 위배출시간을 측정하고 간경변증간자의 위배출시간에 영향을 주는 요인들을 알아보고자 하였다. 2003년 10월부터 2004년 5월까지 울혈성 위염을 동반한 간경변증 환자 6명, 울혈성 위염을 동반하지 않은 간경변증 환자 4명, 20명의 정상인을 대상으로 위배출시간을 검사하였다. 울혈성 위염이 있는 간경변증 환자군의 위배출 시간이 정상 대조군의 위배출 시간보다 길었으나(331.67±317.39분, 66.55±31.39분), 통계적으로 유의한 차이는 없었다(p=0.072). 비록 통계적으로 유의한 차이를 보이지는 않았지만, 울혈성 위염을 가진 간경변증 환자에서의 위배출시간은 정상 대조군과 비교하였을 때 지연되는 양상을 보였다. 이들 자료는 간경변증 환자에서 나타나는 위배출시간 지연의 병태생리에 울현성 위염이 연관되어 있을 가능성에 대해 제시하고 있다. Patients with liver cirrhosis frequently complain gastrointestinal symptoms. Endoscopic feature of patients with cirrhosis often included congestive gastropathy. Little attention has been directed to the possible effect of portal hypertension on the motor function of the gastrointestinal tract. In this study, we evaluated the gastric emptying time in cirrhotic patients with congestive gastropathy and the factors causing the delay of gastric emptying time in patients with cirrhosis. Between October 2003 and May 2004, 6 Cirrhotic patients with congestive gastropathy, 4 Cirrhotic patients without congestive gastropathy, and 20 controls were participated in this study. The gastric emptying time was longer in cirrhotic patients with congestive gastropathy than in controls (331.67±317.39 vs 66.55±31.39 minutes), but there was no statistically significant difference (p=0.072). Although there was no statically significant difference, the gastric emptying time was more delayed in cirrhotic patients who had congestive gastropathy than normal controls. These data suggest a possibility that congestive gastropathy may contribute to pathogenesis of delayed gastric emptying in cirrhosis.
