  • Different neurodegenerative disorders like prion disease, is caused by protein misfolding conformers. Reverse-transfected cytosolic prion protein (PrP) and PrP expressed in the cytosol have been shown to be neurotoxic. To investigate the possible mechanism of neurotoxicity due to accumulation of PrP in cytosol, a PrP mutant lacking the signal and GPI (CytoPrP) was introduced into the SH-SY5Y cell. MTT and trypan blue assays indicated that the viability of cells expressing CytoPrP was remarkably reduced after treatment of MG-132. Obvious apoptosis phenomena were detected in the cells accumulated with CytoPrP, including loss of mitochondrial transmembrane potential, increase of caspase-3 activity, more annexin V/PI-double positive-stained cells and reduced Bcl-2 level. Moreover, DNA fragmentation and TUNEL assays also revealed clear evidences of late apoptosis in the cells accumulated CytoPrP. These data suggest that the accumulation of CytoPrP in cytoplasm may trigger cell apoptosis, in which mitochondrial relative apoptosis pathway seems to play critical role.

  • This study aimed to confirm the induction of resistance to other drug classes by treating Mycobacterium abscessus with moxifloxacin, a fluoroquinolone used for treating nontuberculous mycobacteria infection, and to obtain genetic data for improving treatment. The reads were assembled and analyzed using reference strain sequence data, and the whole-genome and transcriptome sequences of four strains (MD2, MD4, MD6, and MD8) were reported. Antibiotic resistance was not induced by moxifloxacin treatment; however, transcriptomic analysis revealed that the expression of genes responding to stress was upregulated.

  • Moyamoya disease is a cerebrovascular condition that results in the narrowing of the vessels of the circle of Willis and collateral vessel formation at the base of the brain. Although relationships between Graves' disease and cerebrovascular accidents in Moyamoya disease are obscure, the coexistence of the two diseases is noteworthy. Moyamoya disease has been rarely reported in adolescent patients with thyrotoxicosis. Recently, we encountered two adolescent Korean patients with Moyamoya disease associated with Graves' disease who presented with episodic right-sided hemiparesis and syncope. These two girls who had Graves' disease had no history of other diseases or head trauma. A thyroid function test revealed a euthyroid state and a high thyroid-stimulating hormone (TSH) receptor antibody titer at that time. The patients were diagnosed with Moyamoya disease based on brain magnetic resonance angiography and cerebral four-vessel angiography. The patients underwent cranial revascularization by encephalo-duroarterio-synangiosis as soon as a diagnosis was made, which resulted in successful symptom resolution. They fared well and had no additional neurological symptoms as of their last follow-up visits. Here, we report these two cases of confirmed Moyamoya disease complicated by Graves' disease with a review of the literature, and discuss the possible association between the two diseases. To our knowledge, this is the first report in South Korea on Moyamoya disease associated with Graves' disease in adolescents with a euthyroid.

  • Lyme disease, or Lyme borreliosis. is an infection caused by spirohete Borrellia burgdorferi. This disease was recognized in Lyme, Conneticut U.S.A. in 1975. The onset of the disease is usually heralded by the appearance of a pathognomic skin lesion, known as erythema chronicum migrans, and accompanied by flue like or meningitis like symptoms. Unless treatment is initiated early, the disease usually disseminated, often resulting carduac, neurologic, or joint manifestations. All stages of the disease are usually curable by appropriate antibiotic therapy, and can prevent severe late cardiac, neurologic, and joint complications. Lyme disease is typically defined by clinical evidence supported by serologic test. The diagnosis require serologic confirmantion of erythema chronicum migrans, occurring in patient in nonendemic countries. Determination of antibody titer against B. burgdorferi by enzyme linked immunosorbent assay(ELISA) currently the most practical diagnostic test. Currently Lyme disease occurs in U.S.A. Europe, and Australia. It has recently recognized in China, Japan, and Soviet Union also. In United States, Lyme disease is most common vector borne infection. There is no reported case of patients with this disease in Korea. But the vector of this disease, -Ixodes ticks- had been identified in Korea. And Korea is geographically closely related to China and Japan where Lyme disease is already reported. We expect first case of Lyme disease could he reported in near future. We review the clinical manifestations and diagnostic method of Lyme disease.

  • Recently, several researches indicated the relationship between oral condition and respiratory disease such as pneumonia and chronic obstructive pulmonary disease (COPD). Respiratory disease is known as common chronic disease in the elderly increasing mortality and morbidity. In this study, we have reviewed the association between oral disease and respiratory disease in the elderly. The related data were searched and collected from abroad and domestic studies. The studies included the randomized controlled clinical trials (RCTs), longitudinal, cohort, case-control, and systematic review studies. With the data from the studies, we concluded that poor oral hygiene or periodontal disease can influence the pneumonia in the elderly. Further studies will be needed to investigate the association between oral disease and COPD.
