Lymphocyte recruitment and activation have been implicated in the progression of cerebral ischemia-reperfusion (I/R) injury, but the roles of specific lymphocyte subpopulations and cytokines during stroke remain to be clarified. Here we demonstrate that the infiltration of T cells into the brain, as well as the cytokines interleukin-23 (IL-23) and IL-17,(More)
Aggressive natural killer-cell leukemia (ANKL) is a rare form of large granular lymphocyte leukemia, which is characterized by a systemic proliferation of NK cells. The clinical features of 22 ANKL cases were analyzed. Hepatomegaly (64%), splenomegaly (55%) and lymphadenopathy (41%) were also frequently observed. Leukemic cells were identified as CD1-,(More)
Platelet derived growth factor (PDGF)-B plays a neuroprotective role in brain damages, including ischemic stroke. It has been suggested recently that PDGF receptor β (PDGFRβ) expressed in brain pericytes as well as in neurons and astrocytes may mediate the neuroprotective role of PDGF-B. The aims of this study were to elucidate the roles of PDGFRβ signaling(More)
Fibrosis is concomitant with repair processes following injuries in the central nervous system (CNS). Pericytes are considered as an origin of fibrosis-forming cells in the CNS. Here, we examined whether platelet-derived growth factor receptor β (PDGFRβ), a well-known indispensable molecule for migration, proliferation, and survival of pericytes, was(More)
BACKGROUND Gene therapy may be a promising approach for treatment of brain ischemia, although the efficiency of postischemic gene therapy is not established. Our goal in this study was to examine the effects of gene transfer of interleukin-10 (IL-10), an antiinflammatory cytokine, after induction of brain ischemia. METHODS AND RESULTS Brain ischemia was(More)
Pelvic endometriosis associated with massive ascites is an unusual occurrence. Only 12 cases have been reported since 1954 when Brews first described this entity. The authors present two cases recently encountered at Saga Medical School Hospital. Clinical courses and operative findings are described and other cases from the literature are reviewed. The(More)
OBJECTIVE The aim of this study was to evaluate the prognostic significance of steroid hormone receptors in endometrial carcinoma using immunohistochemical staining for progesterone receptor (PR) and estrogen receptor (ER). METHODS We evaluated the correlation between PR/ER immunohistochemistry and age, clinical stage, tumor grade, myometrial tumor(More)
The C242T polymorphism of p22phox, a component of NAD(P)H oxidase, may have an impact on cardiovascular diseases; however, the association between this polymorphism and brain infarction is not fully understood. Here, we investigate the relationship between the C242T polymorphism and brain infarction in Japan. We recruited 1055 patients with brain infarction(More)
In the pathogenesis of cervical squamous cell carcinoma, an inverse correlation between human papillomavirus (HPV) infection and mutation of the p53 anti-oncogene has been suggested. Much less is known of a possible correlation in the case of adenocarcinoma of cervix. Twenty-five cervical adenocarcinomas and 7 adenosquamous carcinomas were analyzed for(More)
