This study investigated the effects of L-glutamine (Gln) supplementation on growth performance, physiological traits, heat shock proteins (HSPs), and gene expression related to muscle and adipose tissue development in Hanwoo steers under heat stress (HS) conditions. Eight Hanwoo steers (initial body weight [BW] 570.7 ± 43.6 kg, months of age 22.3 ± 0.88) were randomly separated into two groups, control and treatment, and supplied with the concentration (1.5% of BW kg/day/head) and rice straw (1.5 kg/day/head). The treatment group were fed the Gln supplementation (0.5% of concentration, as-fed basis) once a day at 08:00 h. Blood samples for the assessment of haematological and biochemical parameters and the separation of peripheral blood mononuclear cells (PBMCs) were collected four times, at 0, 3, 6, and 10 weeks of the experiment. Feed intake was measured daily. BW to analyze growth performance and hair follicle collection to analyze the expression of HSPs were executed four times at 0, 3, 6, and 10 weeks. To analyze gene expression, longissimus dorsi muscle samples were collected by biopsy at the end of the study. As a result, growing performance, including final BW, average daily gain, and gain-to-feed ratio, were not different between the two groups. Leukocytes including lymphocytes and granulocytes, tended to increase in the Gln supplementation group (p = 0.058). There were also no differences in biochemical parameters shown between the two groups, except total protein and albumin, both of which were lower in the Gln supplementation group (p < 0.05). Gene expressions related to muscle and adipose tissue development were not different between the two groups. As temperature-humidity index (THI) increased, HSP70 and HSP90 expression in the hair follicle showed a high correlation. HSP90 in the hair follicle was decreased in the treatment group compared with the control group at 10 weeks (p < 0.05). Collectively, dietary Gln supplementation (0.5% of concentration, as-fed basis) may not be influential enough to affect growth performance and gene expression related to muscle and adipose tissue development in steers. However, Gln supplementation increased the number of immune cells and decreased HSP90 in the hair follicle implying HS reduction in the corresponding group.

Amyotrophic lateral sclerosis (ALS) is a progressive disorder that causes degeneration of motor neurons of the brain and spinal cord. ALS is a progressive, fatal neuromuscular disease characterized by loss of motor neurons leading to muscle weakness. Sensation and mental function stay intact during the course of the disease. ALS is characterized by both upper and lower motor neuron damage. Diagnosis includes magnetic response imaging (MRI) electromyogram (EMG), muscle biopsy, and blood test. There is no cure for ALS. We recently observed three cases of ALS. The patients were diagnosis with ALS by EMG and symptoms. This report was conducted to evaluate how oriental medical treatment can affect ALS. We report the change of their symptoms through oriental medical treatment compared with taking riluzole.

An 18-year-old boy was admitted with chest discomfort, nausea, and dyspnea at rest. At the age of 3 years, he underwent muscle biopsy and dystrophin gene analysis owing to an enlarged calf muscle and elevated serum kinase level (6,378 U/L) without overt weakness; based on the results, Becker muscular dystrophy (BMD) was diagnosed. The dystrophin gene showed deletion of exons 45 to 49. He remained ambulant and could step upstairs without significant difficulties. A chest roentgenogram showed cardiomegaly (cardiothoracic ratio, 54%), and his electrocardiogram (ECG) showed abnormal ST-T wave, biatrial enlargement, and left ventricular hypertrophy. The 2-dimensional and M-mode ECGs showed a severely dilated left ventricular cavity with diffuse hypokinesis. The systolic indices were reduced, including fractional shortening (9%) and ejection fraction (19%). Despite receiving intensive medical treatment, he died from congestive heart failure 5 months after the initial cardiac symptoms. We report a case of BMD with early-onset dilated cardiomyopathy associated with deletion of exons 45 to 49. Early cardiomyopathy can occur in BMD patients with certain genotypes; therefore, careful follow-up is required even in patients with mild phenotypes of BMD.

Purpose: Dermatofibrosarcoma protuberans(DFSP) is a moderate - degree malignant tumor of soft tissue from dermis to fat layer with high recurrences(11% to 73%) due to its local infiltrative characteristic. Many debates and controversies in deciding accurate surgical margin were presented before, but references about depth of invasion and appropriate surgical excision level were not properly made out. Therefore, we tried to identify the degree of tissue invasion of DFSP. Methods: Twenty patients, including 8 patients with recurrent lesions, over last 10 years were reviewed retrospectively. Different surgical margins were applied according to the location and based on histopathologic result, we have defined as a 'deep tissue invasion' if there were infiltration of tumor cell into fascia or underlying muscle layer was present. All invaded tissue including dermis, fat, fascia and muscle were excised until no tumor cell was found during intraoperative frozen section biopsy. And comparative analysis of deep tissue invasion according to age, primary site, duration of disease and recurrence was done. Results: Thirteen patients(65%) showed deep tissue invasion and incidence was found to be increasing with age(over 30 years old). All patients with DFSP on head and neck region revealed deep tissue invasion followed by trunk(54%) and lower extremities(50%). There was no relationship between duration of disease and deep tissue invasion. Conclusions: It is clear that many cases of DFSP had a deep tissue invasion. And high prevalence of deep tissue invasion with age, primary site was intimately associated. So, underlying deep tissue must be completely examined and excised sufficiently throughout the operation for clear resection of DFSP with no recurrences, especially when age is over 30s and on head and neck region.

The musculoskeletal system can be involved as an extra-intestinal manifestation of inflammatory bowel disease. Among these, myositis in ulcerative colitis (UC) is very rare. A 14-year-old girl was admitted due to severe shoulder tenderness. She had complained of left jaw pain and swelling for the past 10 days. Inflammatory markers were elevated with no evidence of infectious etiology. Myositis was suspected by shoulder magnetic resonance imaging. Three days after admission, she developed hematochezia. Muscle biopsy and colonoscopy was performed due to worsening left mandibular area pain and persistent hematochezia. Colonoscopy showed consistent findings with UC. She was finally diagnosed with UC with myositis as an extra-intestinal manifestation. She showed a dramatic response to UC treatment. Gastrointestinal symptoms were well-controlled. After 14 months, UC symptoms and muscle pain were aggravated, which were relieved after steroid and cyclosporin treatment. We report a unique case of UC initially presented with myositis, preceding gastrointestinal symptoms.

Myxoma is a locally invasive neoplasm usually involving the jaw bones, typically occurs between the second and fourth decades. This tumor may comprise 3%-6% of odontogenic tumors. Myxomas of the soft tissue of the face are very rare. We present an unusual case of myxofibroma occurring in a 13-year-old man involving the soft tissue of the face. It congenitally occurred and was a 1 cm sized, ovoid in shape, swelling located on the glabella without any symptoms. An excisional biopsy was performed. A well encapsulated ovoid mass was attached to the corrugator supercilli muscle below the frontalis muscle. It was measured 1.1 × 1 × 0.8 cm and completely excised. Histological examination revealed myxofibroma showing stellate and spinde-shaped cells throughout myxoid ground substance. The unusual features of this case are the site of the tumor, which was localized to the non-tooth bearing area of the mandible and its congenital occurrence history.

Angiolymphoid hyperplasia with eosinophilia(ALHE) is an uncommon, benign vascular proliferation with the background of a stroma which is heavily infiltrated by lymphocytes and eosinophils and includes lymphatic follicles with prominent germinal centers. ALHE primarily involves the skin and subcutis in head and neck as various forms of nodules. There has been considerable controversy about the relationship between ALHE and Kimura's disease. Kimura's disease, originally reported by Kimura et el., is an unusual granulation with proliferation of lymphoid tissue. Wells and Whimster published the first report describing a condition that resembled Kimura's disease and designated it as ALHE. For a time being two lesions are thought to be same lesion, but recently they are considered as two different entities, histopathologically. The cause of this disease remains unknown, and physicians have used a variety of treatment modalities including cryosurgery, steriod therapy, electrodesiccation, curettage, radiotherapy, laser therapy and surgical excision. But any treatment modality leaves problem of recurrence because the lesion is not well encapsulated. Being poorly encapsulated, the lesion's remnants are apt to be left and this markes some problems : recurrence and possible adjacent organ injury. In this case we misdiagnosed the lesion as well encapsulated benign mass. We performed excisional biopsy and experienced prolonged operation time and unwanted mentalis muscle injury. We think that the importance of poor encapsulation of ALHE should be stressed. So we report our experience with literature review.

The lymphangioleiomyomatosis(LAM) is a rare disorder, which afflicts mainly young woman of childbearing age, characterized by proliferation of immature smooth muscle cell in the lymphatics. We experienced a case of LAM in 26-years-old pregnant woman, confirmed pathologically by inguinal lymph node biopsy. She has suffered from exertonal dyspnea and dry coughing. The symptoms and chest X-ray were aggravated with pregnancy, but improved after delivery with two times of pregnancy. The chest X-ray showed diffuse reticulonodular infiltration and chest HRCT showed diffuse scattered tiny thin-walled cyst of lung parenchyma. We noted chylous ascites of which triglyceride level is 396 mg/dl. After delivery, the symptoms were getting better. We treated with medroxyprogesterone and planned close observation and follow-up.
