The glial cytoplasmic inclusion (GCI) is a histological hallmark for multiple system atrophy (MSA): these inclusions are found in oligodendrocytes and consist of abnormal granule-coated fibrils of approximately 24- to 40-nm diameter. To clarify the significance of the presence of midkine (MK) in these GCIs, we carried out immunohistochemical, electron and(More)
Living cells produce reactive oxygen species (ROSs). To protect themselves from these ROSs, the cells have developed both an antioxidant system containing superoxide dismutase 1 (SOD1) and a redox system including peroxiredoxin2 (Prx2, thioredoxin peroxidase) and glutathione peroxidase1 (GPx1): SOD1 converts superoxide radicals into hydrogen peroxide(More)
Peroxiredoxin-ll (Prxll) and glutathione peroxidase-l (GPxl) are regulators of the redox system that is one of the most crucial supporting systems in neurons. This system is an antioxidant enzyme defense system and is synchronously linked to other important cell supporting systems. To clarify the common self-survival mechanism of the residual motor neurons(More)
Serum thymic factor (FTS), a thymic peptide hormone, has been reported to attenuate the bleomycin-induced pulmonary injury and also experimental pancreatitis and diabetes. In the present study, we investigated the effect of FTS on cis-diamminedichloroplatinum II (cisplatin)-induced nephrotoxicity. We have already demonstrated that cephaloridine, a(More)
One of the pyrimidine compounds, 2-piperadino-6-methyl-5-oxo-5,6-dihydro(7H)pyrrolo[3,4-d]pyrimidine (MS-818), has neurotropic effects in vitro. Therefore, we studied the effect of MS-818 on the regeneration of the peroneal nerve in C57BL/6J mice after a crush injury. Two test groups, which received a daily intraperitoneal injection of 5 mg/kg or 10 mg/kg(More)
Facteur thymique serique (FTS), a thymic hormone with nonapeptide is involved in T cell differentiation in intestine. Here we investigated the effect of FTS on dextran sulphate sodium (DSS)-induced colitis. BALB/c mice were subcutaneously treated with 1 mug/mouse/day of FTS daily. FTS did not affect the course of acute colitis induced by DSS as assessed by(More)
The protective effect of synthetic serum thymic factor (FTS) nonapeptide on lipopolysaccharide (LPS)-induced pancreatic cell damage in 10-week-old BALB/c male mice was investigated. Mice were divided into three groups. Group I was treated with LPS (10 micro g/head; i.p.) (LPS-treated mice). Group II was administered with FTS (50 micro g/head; i.p.) 24 hr(More)
OBJECTIVE Some pyrimidine analogues have been found to induce differentiation of several human myeloid leukemia cells. Newly synthesized heterocyclic pyrimidine derivatives promote neurite outgrowth and survival in neuronal cell lines. In this study, the growth-inhibiting and differentiation-inducing effects of these pyrimidine derivatives on human myeloid(More)
We investigated 115 individuals in Tokyo from two groups of persons with conspicuous nevi on the head, neck, and arms, etc. (nevus-positive group) and persons who do not exhibit such nevi (nevi-negative group) interviewing them to determine whether they suffered from allergic rhinitis/conjunctivitis (pollinosis) and examining them for the presence and(More)
Tumor necrosis factor-alpha (TNF-alpha) is a cytokine considered to play a key role in beta-cell destruction in insulin-dependent diabetes mellitus (IDDM). Serum thymic factor (Facteur thymique serique; FTS) is a nonapeptide thymus hormone known to inhibit IDDM in a mouse model. In this study, the effect of TNF-alpha on the murine pancreatic beta-cell line(More)
