Pancreatic pseudocysts,which account for 70%-90% of pancreatic cystic lesions,characteristically are non-epithelially lined cystic cavities that are contiguous with the pancreas. Pancreatic pseudocysts can be caused by acute,chronic or traumatic pancreatitis and should be differentiated from other pancreatic diseases with cystic appearances,especially cystic neoplasms. We report a unique case of a pancreatic pseudocyst filled with semisolid lipids,which appeared by endoscopic ultrasound as a solid mass,and was therefore resected.

Alzheimer’s disease(AD)is the most prevalent neurodegenerative disease,and the number of patients with AD is estimated to double by 2060(Alzheimer’s Association,2022).The AD mortality rate has increased by 145%over the last decade,the largest increase among the ten leading causes of death in the US(Alzheimer’s Association,2022).

AIM： Many cirrhotic patients have muscular symptoms and rhabdomyolysis. However, myopathy associated with liver cirrhosis has not been established as a disease entity. We evaluated the clinical significance of acute myopathy associated with liver cirrhosis. METHODS： We retrospectively reviewed the medical records of 5440 cirrhotic patients who had been admitted to Gyeongsang National University Hospital from August 1997 to January 2003. Among these, 99 developed acute myopathies, and they were analyzed with respect to clinical and laboratory parameters, and outcomes. RESULTS： The Child-Pugh classification at the time of myopathy onset was A in 3（3.1%） cases, B in 33（33.3%）, and C in 63 （63.6%）. Infection was identified as the most predisposing factor to myopathy. Fifty percent of 18 idiopathic cases who were tested for influenza antibody were positive. Forty-two of the 99 cases were complicated by acute renal failure, and 25 （59.5%） of these expired. Apart from 6 cases lost to follow-up, 64 of 93 recovered, giving a mortality rate of 31.2%. Mortality was higher in Child-Pugh class C than in B or A. CONCLUSION： Acute myopathy can develop as a serious complication in liver cirrhosis. Its frequency, severity and mortality depend on underlying liver function, and are higher in decompensated liver cirrhosis. Influenza should be considered as an etiologic factor in idiopathic cases. It is proposed that acute myopathy associated with liver cirrhosis be called ＇hepatic myopathy; and that careful monitoring for hepatic myopathy is necessary in the patients with advanced liver cirrhosis.

OBJECTIVE: To investigate the effects of Gyejibokryeong-Hwan(Guizhifuling-wan, GBH) on muscle injury in a mouse model of muscle ***: C57/BL6 mouse biceps femoris muscles were injured using the drop-mass method and injured animals were treated orally with GBH(50,100, or 500 mg/kg) once a day for 7 d. Open field and treadmill running tests were performed to assess functional recovery from muscle injury. The production of pro-inflammatory cytokines was examined by enzyme-linked immunosorbent assay and Western blotting analysis. Expression of the muscle regeneration biomarkers, myoblast determination(Myo D), myogenic factor 5(Myf5), and smooth muscle actin(α-SMA), in the biceps femoris muscle was investigated at the protein and m RNA level by Western blotting and real time-PCR, respectively. Histological analysis was performed using hematoxylin and eosin staining. Finally, myosin heavy chain production was investigated in differentiated C2C12 myoblasts in the presence of ***: GBH treatment markedly improved locomotion and running behavior. GBH significantly inhibited the secretion of monocyte chemoattractant protein-1 into the bloodstream in muscle-contused animals. The levels of Myo D, Myf5, and α-SMA protein and m RNA were significantly up-regulated by GBH in injured muscle tissue. Histological studies suggested that GBH facilitated recovery from muscle damage. However, GBH did not induce the production of myosin heavy chain in ***: Overall, the present study suggested that GBH improves the recovery of the injured muscles in the mouse model of muscle contusion.

Antimicrobial activity of methanol extract from bulb of Scilla scilloides as well as the purified eucosterol oligosaccharides (EOs) against bacteria, fungi and alga was evaluated in vitro using paper disc bioassay. EOs including scillascilloside E-1, E-2, E-3 and G-1 were isolated from the bulbs by methanol extraction, gel filtration on Sephadex LH-20 and preparative HPLC. The metabolites were identified by MS (HR-FAB-MS) and 1H- and 13C-NMR spectral data analyses. Methanol (MeOH) extract and purified compounds, EOs showed a selective inhibitory activity against eukaryotic cells including fungal species such as Aspergillus flavus, Candida albicans, Pyricularia oryzae and an alga such as Chlorella regulsris at the concentration of 200 μg/paper disc, but little active against bacteria. Out of four EO compounds, Scilla-scilloside E-3 revealed the highest activity. These results show that the MeOH extract and EOs from the medicinal plant, S. scilloides, may be applied as a natural fungicide or a food preservative for control of molds.

Previous reports of a solitary metastatic hepatocellular carcinoma have been rare. Because this tumor has a different treatment modality and prognosis, an accurate differential diagnosis is essential. Here we report a rare case of a solitary chest wall metastasis from unknown primary site of hepatocellular carcinoma. It involves a 51-year-old man who was admitted to our hospital because of a palpable left upper chest wall mass. The mass was resected and pathologic examination confirmed a diagnosis of metastatic hepatocellular carcinoma. Despite our investigation, no evidence was found that indicated the primary origin of the hepatocellular carcinoma. Four months later, the patient was admitted again because of spinal cord compression at the third and fourth thoracic vertebrae. Emergent decompressive laminectomy was performed and microscopic features revealed the same pathology as the initial chest wall mass resected 4 months earlier. After one year, a follow-up abdominal computed tomography （CT） still revealed no evidence of primary hepatocellular carcinoma.
