Objectives Objective of this study is to investigate the role of paraspinal muscles by examining the correlation between slip percentage (SP) of spondylolisthesis and fatty infiltration of lumbar paraspinal muscle. Methods Retrospective analysis was performed on 45 patients diagnosed with spondylolisthesis based on medical records. Using T2-weighted axial magnetic resonance imaging, cross-sectional areas (CSAs) of psoas major (PM), multifidus (MU) and erector spinae (ES) were calculated and divided by CSA of lower level vertebral body (VB). SP was measured using sagittal T2-weighted images. Correlation of SP with muscle relative cross-sectional area (RCSA) and muscle fatty infiltration by Goutallier classification was respectively analyzed using Spearman correlation. Statistic assessment conducted by Wilcoxon signed rank test and paired t-test using program GraphPad prism 5 (GraphPad Software, Inc., San Diego, CA, USA). Results Spondylolisthesis forward slip percentage by Taillard's method was negatively associated with both side MU RCSAs. No significant correlation was found between PM RCSA, ES RCSA and SP. Forward slippage was significantly correlated with fatty infiltration of lumbar paraspinal muscle measured by Goutallier classification. Conclusions This study is to understand the role of paraspinal muscle affecting spinal instability by investigating correlation between statistical deviation of lumbar muscle characters (RCSA, fatty infiltration of lumbar muscle) and SP. We found that spondylolisthesis SP is positively related to fatty infiltration of lumbar paraspinal muscle. and is negatively associated with both side MU RCSAs.

Background: The Korean Shoulder Scoring System (KSS) is a reliable and valid procedure for discriminative assessment of the clinical status of patients with rotator cuff tears. This study evaluates the correlation between the preoperative KSS and factors in patients with rotator cuff tears. Methods: From November 2009 to June 2016, 970 patients who underwent arthroscopic rotator cuff repair were retrospectively evaluated. A total of 490 patients met the study criteria. Preoperative factors included age, sex, symptom duration, mediolateral (ML) and anteroposterior (AP) tear size, acromiohumeral distance (AHD), tangent sign, tendon involvement (type I, supraspinatus; type II, supraspinatus and subscapularis; type III, supraspinatus and infraspinatus; type IV, all 3 tendons), fatty infiltration of rotator cuff muscles (group I, Goutallier stages 0 and 1; group II, Goutallier stages 2, 3, and 4), and KSS. Results: Old age, ML tear size, and AP tear size negatively correlated with the preoperative KSS (p<0.001). AHD showed a positive correlation with the preoperative KSS (p<0.001). A significantly inferior preoperative KSS was found in females and type III tendon involvement (p<0.001). For supraspinatus and infraspinatus, the preoperative KSS of group II fatty infiltration showed a significantly lower score than group I fatty infiltration (p<0.05). Conclusions: A relatively lower preoperative KSS was associated with old age, large tear size, narrow AHD, female, type III tendon involvement, and group II fatty infiltration of the supraspinatus and infraspinatus. Our study indicates that preoperative KSS can be a good measurement for the preoperative status of patients with rotator cuff tears.

The toxicity and histopathologic changes of diazinon (O, O-diethy-O-(2-isopropyl-6-methyl-4-pyrimidinyl)phosphorothioate) was investigated in rat. Rat was treated with diazinon (100 mg/kg/day) by oral administration for 12 days. The experimental results were summarized as follows. Biochemical parameters such as ALT, AST, LDH and glucose in serum were significantly increased and hematological parameters such as Hb, Hct and PLT in blood were slightly increased in treated groups. Also the activities of serum cholinesterase were very significantly decreased in treated groups. In the histopathological changes, the normal lobular architectural pattern of the liver was well preserved in all treated groups. However, vacuolation or fatty change were represent in hepatocytes. Sections of liver from rats treated with diazinon for 3 and 6 days contained slight lipid infiltration in the form of small droplets randomly distributed that were graded minimal (＋) or moderate (＋＋) compared with the respective control condition. After 9 days, there were numerous small and large vacuoles in the terminal hepatic venule and perilobular areas of many serial sections of these rats indicative of fatty infiltration which were graded moderate (＋＋) and severe (＋＋＋). After 12 days, fatty infiltration progressed periportal tract areas and graded severe (＋＋＋) and very severe (＋＋＋＋) in experimental groups. Note absence of cellular necrosis or inflammation.

Chronic exposure to ethanol induces cumulative damage to the liver starting from fatty infiltration to cirrhosis depending on the dose and duration of exposure. The whole process leading to the development of alcoholic liver disease is very complex and the mechanisms involved are not fully understood. Among many experimental animal models, Lieber-DeCarli liquid diet provides moderate to severe pathophysiological outcome depending on the compositional changes. In the present study, we investigated the temporal changes in the early phase hepatic disease in rats fed with standard Lieber-DeCarli diet. Male Wistar rats were fed with Lieber-Decarli ethanol diet for 6 weeks and the liver samples were obtained after 2, 4 and 6 weeks. Mild fatty infiltration was observed in 2 weeks of feeding and it became evident in 4 and 6 week samples. The level of hepatic triglyceride showed a good agreement with the data obtained in the pathological analysis. Feeding mice with ethanol diet resulted in the maturation and translocation of SREBP-1 to nucleus in the liver. Western blot analysis of the pooled liver sample of control and ethanol fed animals showed a clear-cut time-dependent increase in the expression of nSREBP-1. These data provide important information for selecting proper time point in experimental intervention study in the field of drug development for alcoholic liver disease.

Background: Popeye deformity is common after rupture of the biceps muscle's long head tendon. Herein, we report on histological changes in biceps brachii muscles following tenotomy of the long head biceps tendon. Methods: Twelve Sprague-Dawley rats (12-week-old) underwent tenotomy of the long head biceps tendon in the right shoulder. At postoperative weeks 4, 7, and 10, the operative shoulders were removed by detaching the biceps brachii muscle from the glenoid scapula and humerus; the opposite shoulders were removed as controls. H&E staining was performed to elucidate histological changes in myocytes. Oil-red O staining was performed to determine fatty infiltration. Myostatin antibody immunohistochemistry staining was performed as myostatin is expressed by skeletal muscle cells during myogenesis. Results: H&E staining results revealed no changes in muscle cell nuclei. There were no adipocytes detected. Compared with that of the control biceps, the cross-sectional area of the long head biceps was significantly smaller (p=0.00). Statistical changes in the total extent of the 100 muscle cells were significant (p=0.00). Oil-red O staining revealed no fatty infiltration. Myostatin antibody immunohistochemical staining revealed no significant difference between the two sides. Conclusions: Muscular changes after tenotomy of the long head biceps included a decrease in the size of the individual muscle cells and in relative muscle mass. There were no changes observed in muscle cell nuclei and no fatty infiltration. Moreover, there were no changes detected by myostatin antibody immunohistochemistry assay.

In order to compare the effects of epinephrine, cortisone or insulin on the hepatic storage of triglycerides, the fatty liver was induced in mice by the subcutaneous injection for 30 days of either epinephrine, cortisone or insulin. The morphological characteristics of fatty liver in relation to the inducing agents was observed with the following results. 1. The fatty liver induced by epinephrine or cortisone was characterized by the centrilobular accumulation of triglycerides although the degree of accumulation by epinephrine appeared to be much higher than that by cortisone. 2. The fatty liver produced by insulin, however, was characterized by the infiltration of small-sized lipid droplets scattering all over the hepatic lobules.

Chronical intake of alcohol can cause alcoholic fatty liver. Fatty liver is caused by fat infiltration: the state of high rate of fat in liver cells and by losing the balance between the synthesis and the secretion of fatty acid. It could be developed into liver necrosis and cirrhosis. Ka-Mi-Chung-Gan-Tang (KMCGT) is a decoction used for fatty liver as oriental medicines in China. The prescription is composed of Ginseng Radix, Bupleuri Radix, Scutellariae Radix, Pinelliae Tuber, Artemisiae capillaris Herba, Gardeniae Fructus, Zingiberis Rhizoma, Zizyphi Fructus and Glycyrrhizae Radix etc. We have induced alcoholic fatty liver by ethanol administration (6 g/kg, single dose/day, for a week) on rats and observed changes of triglyceride, cholesterol and lipid peroxidation in liver tissues of them. Also we checked the activities of GOT and GPT in blood of rats. KMCGT inhibited significantly the increase of triglyceride, cholesterol, lipid peroxidation level and effectively the increase of malondialdehyde (MDA).

This study was to investigate the effects of Gibangganbang on the liver injury induced dimethylnitrosamine, CCl4, ethanol and partial hepatectomy. Hydroxyproline, hepatic fibrosis, hepatic inflammatory cell infiltration, fatty value, lipidoperoxide levels, glutathione levels, mitotic index, contents of protein in the serum and liver tissues were measured and observed. The results obtained were as follows. 1. The increasing level of hydroxyproline volume induced by dimethylnitrosamine in mice was decreased by the oral administration of Gibangganbang. 2. The degree of hitological fibrosis and hepatic inflammatory cell infiltration induced by $CCl_4$ was decreased by the oral administration of Gibangganbang. 3. The degree of fatty value and the increasing level of lipidoperoxide in liver tissues was decreased by the oral administration of Gibangganbang. 4. The level of glutathione in liver tissues was increasing by the oral administration of Gibangganbang. 5. The increasing level of microsomal lipidoperoxide in vitro assay was decreasing by the oral administration of Gibangganbang. 6. The increasing level of the mitotic index, weight of liver, contents of protein, RNA and DNA synthesis of the liver tissues after partial hepatectomy was activated by the oral administration of Gibangganbang. These results suggest that Gibangganbang not only inhibits liver cirrhotic change and ethanol-induced fatty change but also activates antioxidant enzymes and regeneration ability ocf liver.

목 적: 소아비만의 중요한 합병증 중 하나인 지방간을 진단함에 있어 ALT치와 CT 및 간생검 소견간의 상관관계를 살펴봄으로써, 선별검사로서 ALT치의 유용성과 확진검사로서 CT 및 간생검의 필요성을 알아보고자 한다. 대상 및 방법: 1990년 3월부터 1997년 12월까지 서울적십자병원 소아과에 내원하여 단순비만으로 진단 받은 78명 중 지방간 진단을 위해 CT를 실시한 26명을 대상으로 하였으며, 생화학검사 중 지방간의 선별검사로서 보다 특이성이 높은 ALT치가 지나치게 높거나 비만도가 심한 비만아들 중 15례에서 간생검을 실시하였다. 이들을 ALT치에 따라 3개 군으로 분류하고 각 군별로 신체계측지수, CT 및 간생검상 지방침착도 간의 상관관계를 비교 분석하였다. 결 과: 1) ALT치와 신체계측지수간의 상관관계: 대상 비만아 26례 중 ALT치는 17례(63.4%)에서 이상 상승(>30 IU/L)되었으나, ALT치의 상승과 신체계측지수들(비만도, RI, BMI, 체지방률) 간에는 유의한 상관관계가 없었다(p>0.05) 2) CT상 지방침착도와 ALT치 및 신체계측지수 간의 상관관계: 26례 중 13례(50%)에서 CT상 정상이었고, 나머지 13례는 정도의 차이는 있으나 모두 간음영이 증가된 지방간 소견을 보였다. CT상 지방간의 정도와 ALT치의 상승간에는 유의한 상관관계가 있었으나(p=0.01), 신체계측지수와는 유의한 상관관계가 없었다(p>0.05). 3) 간 생검상 지방간의 정도와 비만도, ALT치와의 상관관계: 26례 중 15례에서 간 생검을 실시한 결과, 1례에서 정상이었고 나머지 14례에서 모두 지방간 소견을 보였다. 그러나 간 생검상 정상인 1례는 고도비만이었으나 ALT치는 정상치였고, 중등도의 지방간 소견 보인 3례 중 1례는 고도비만이었음에도 ALT치는 정상이었으며 2례는 ALT치가 정상이거나 약간 증가하였으며, 심한 지방간 소견 보인 9례 중 1례는 경한 비만이었으나 ALT는 158 IU/L로 심한 상승을 보였다. 간 생검상 지방간인 14례를 지방침착도에 따라 3개 군으로 분류하여 비만도와 ALT치를 비교분석한 결과 비만도와 간 생검 소견간에는 유의한 차이가 없었으나(p>0.05), ALT치와 간 생검상 지방간의 정도간에는 유의한 차이가 있었다(p=0.01). 4) CT와 간 생검 소견간의 상관관계: 26례 중 15례에서 CT와 간 생검 모두를 시행한 결과, CT상 6례는 정상이었고, CT상 지방간 소견 보인 9례에서는 간의 지방침착도에 따른 음영의 변화를 기준으로 한 CT소견과 간 생검상 지방침착도간에 유의한 상관관계를 보였다(r=0.6094). 결 론: 최근 소아비만이 급증 추세에 있고 그에 따른 여러 가지 합병증들은 물론 성인비만으로 이행될 수 있으므로 학교보건 등을 통해 경각심을 높이도록 해야 하며, 특히 비만에 따른 지방간을 진단하기 위한 선별검사인 ALT치 등 생화학적인 간 기능 검사로는 간 손상 정도를 평가할 수 없기 때문에 보다 저비용이며 비침습적인 초음파검사를 적극 활용토록 하고 선별검사 등으로 선정된 고위험군에 대해서는 간 생검을 통해 간 손상 정도를 정확히 평가하고 지속적으로 추적 관리해야 할 것이다.
