  • Critical illness neuromyopathy (CINM) is a common but frequently underdiagnosed condition in critically ill patients that contributes to ventilator weaning failure and limb weakness in intensive care unit (ICU). CINM is subdivided into critical illness polyneuropathy and critical illness myopathy, and the occurrence of these conditions in the ICU is associated with multiple organ failure due to sepsis or certain medications. CINM survivors might have persistent functional disabilities and a poor quality of life. This situation demonstrates the need for efforts to minimize or prevent CINM in critically ill patients. This article provides a current overview of CINM and the associated clinical strategies.

  • Intravesical bacillus Calmette-Guérin (BCG) instillation is an adjuvant treatment for non-muscle-invasive urinary bladder cancer. Although most complications associated with BCG immunotherapy are mild and self-limiting, rare albeit serious complications have been reported. Only a few cases of BCG-related rhabdomyolysis have been reported. In this study, we present the case of a 72-year-old woman who developed severe weakness and hyperCKemia following intravesical BCG instillation. A muscle biopsy was performed, and a diagnosis of drug-induced myopathy was made.

  • Statins, HMG-CoA reductase inhibitors, are known to cause serious muscle injuries (e.g. myopathy, myositis and rhabdomyolysis), and these adverse effects can be rescued by co-administration of coenzyme $Q_{10}$ ($CoQ_{10}$) with statins. The goal of the current research is to assess the efficacy of combined treatment of $CoQ_{10}$ with Atorvastatin for hyperlipidemia induced by high-fat diet in SD rats. 4-week-old Sprague-Dawley male rats were fed normal diet or high-fat diet for 6 weeks. Then, rats were treated with either Statin or Statin with various dosages of $CoQ_{10}$ (30, 90 or 270 mg/kg/day, p.o.) for another 6 weeks. Compared to Statin only treatment, $CoQ_{10}$ supplementation significantly reduced creatine kinase and aspartate aminotransferase levels in serum which are markers for myopathy. Moreover, $CoQ_{10}$ supplementation with Statin further reduced total fat, triglycerides, total cholesterol, and low-density lipoprotein-cholesterol. In contrast, the levels of high-density lipoprotein-cholesterol and $CoQ_{10}$ were increased in the $CoQ_{10}$ co-treated group. These results indicate that $CoQ_{10}$ treatment not only reduces the side effects of Statin, but also has an anti-obesity effect. Therefore an intake of supplementary $CoQ_{10}$ is helpful for solving problem of obese metabolism, so the multiple prescription of $CoQ_{10}$ makes us think a possibility that can be solved in being contiguous to the obesity problem, a sort of disease of the obese metabolism.

  • Objectives Ethanol is a potent inhibitor of muscle protein synthesis. Muscle mass is regulated by the balance between rates of protein synthesis and protein breakdown. Both acute and chronic alcohol consumption inhibits synthesis to a greater extent than degradation. Protein synthesis is more intensely decreased in type II fibers than in type I fibers. Apoptosis has been shown to occur frequently in a variety of tissues in response to chronic alcohol feeding. Increased muscle fiber apoptosis has been shown in alcoholics with myopathy. Pueraria radix has been used for many disorders such as fevers, gastrointestinal disorders, muscle aches, allergies, respiratory problems, skin problems, high blood pressure, migraine headaches, lowering cholesterol and treating chronic alcoholism. We therefore tested the hypothesis that oral treatment with Pueraria radix could reduce the ethanol-induced muscle atrophy. Methods Young male Sprague-Dawley rats were orally given 25% ethanol (5 ml/kg, body weight) daily with Ethanol for 4 weeks. Normal group was similarly administrated with saline. The Rats of Pueraria radix treated group (EtOH+PR) were orally administrated Pueraria radix water extract, and rats of EtOH group were given with the vehicle only. After 4 week, the morphology of gastrocnemius and plantaris muscles were assessed by hematoxylin and eosin staining. The immunoreactivities of pre-apoptotic BAX and anti-apoptotic Bcl-2 proteins were also measured. Results The muscles from rats of EtOH group represented a significant reduction in average cross section area compared to Normal group. EtOH+PR group had increased fiber compared to the EtOH group. Moreover, to investigate the ethanol-induced muscular apoptosis, the immunohistochemical analysis of Bax and Bcl-2 was carried out. The treatment with Pueraria radix (EtOH+PR) significantly decreased BAX expression and increased Bcl-2 expression 4 weeks after ethanol administration when compared with Normal group. Conclusions These results suggest that Pueraria radix water extract has protective effects on chronic alcohol induced myopathy.

  • Objective: Wooden breast (WB) is a novel myopathy affecting modern broiler chickens, which causes substantial economic losses in the poultry industry. The objective of this study was to evaluate the effect of WB abnormality on meat quality, redox status, as well as the expression of genes of the nuclear factor-erythroid 2-related factor 2 (Nrf2) pathway. Methods: A total of 80 broilers (Ross 308, 42 days of age, about 2.6 kg body weight) raised at Jiujin farm (Suqian, Jiangsu, China) were used. Twelve unaffected (no detectable hardness of the breast area) and twelve WB-affected (diffuse remarkable hardness in the breast muscle) birds were selected from the commercial broiler farm according to the criteria proposed by previous studies. Results: The results indicated that WB showed histological lesions characterized by fiber degeneration and fibrosis, along with an increase of muscle fiber diameter (p<0.05). Moreover, higher pH value, lightness, yellowness, drip loss and cooking loss were observed in the WB group (p<0.05). Compared with the normal breast (NOR) group, the WB group showed higher formation of reactive oxygen species (p<0.05), increased level of oxidation products and antioxidant activities (p<0.05), accompanied with mitochondrial damages and lower mitochondrial membrane potential (p<0.05). Meanwhile, the relative mRNA expressions of Nrf2 and its downstream antioxidant genes including heme oxygenase-1, NAD(P)H qui none dehydrogenase 1, glutathione peroxidase, superoxide dismutase, and glutamate-cysteine ligase were higher than those of the NOR group (p<0.05). Conclusion: In conclusion, WB myopathy impairs meat quality by causing oxidative damages and mitochondrial dysfunction in broilers, even though the activated Nrf2/antioxidant response element pathway provides protection for the birds.

  • 최근에 고령화 사회와 정보화 사회에 따른 운동량의 부족으로 인한 근육질환과 뇌졸중, 치매, 파킨슨병, 운동신경 질환 등 근질환 발생률이 급증하고 있으며 발생률을 조사한 결과, 남성경우 2배이상 증가했고, 파킨슨병과 운동신경질환 등 사망률은 남녀가 약 50%씩 늘어난 것으로 나타났다. 환경적 요인이 크게 작용하며 특히, 우려할 것은 급속히 증가하는 노인인구로 인한 노인성 질환 및 근질환의 대책이 무엇보다 요구되는 실정으로 발병하면 치료가 어렵고, 후유증이 심각하므로 무엇보다 예방이 중요하다 위험인자와 발생위험을 조기에 예방할 수 있도록 간접운동을 확인할 수 있는 시 저주파-초음파 장비를 통해 시중에 나와있는 장비의 기준을 정하고 특성시험과 모델링화 하여 성능의 우수성을 입증하여 정리하였다. 차후 시스템을 보완하면 다른 질병의 근질환 환자에도 적용이 될 것이고, 본 연구에서는 시제품을 직접 제작하여 비정형화 특성을 연구하고 접근해 보고자 노력하였다.

  • A 9-year-old, mixed-breed, castrated male dog presented with a one-week history of severe vomiting. Abdominal radiography showed a dilated small intestine loop. Abdominal ultrasonography showed small-intestine distension up to 5 cm in diameter without mechanical obstruction. During exploratory laparotomy, an aperistaltic ileal segment was resected. There was no narrowed cavity in the resected plane. Histopathologic and immunohistochemical findings confirmed visceral myopathy due to intestinal adenocarcinoma in the ileum and revealed partial destruction of the longitudinal and circular muscles with fibrosis. Chronic intestinal pseudo-obstruction caused by adenocarcinoma was diagnosed after considering the above investigative results.
