BACKGROUND AND PURPOSE The most common strategy for treating patients with acute ischemic stroke is thrombolytic therapy, though only a few patients receive benefits because of the narrow time window. Inflammation occurring in the central nervous system (CNS) in association with ischemia is caused by immune cells including monocytes and involved in lesion(More)
Previous studies have demonstrated the immunomodulatory effects of cisplatin under certain conditions. The present study was designed to clarify whether cisplatin modulates the expression of surface antigens, especially human leukocyte antigen (HLA), on human tumor cell lines and/or augments the susceptibility and binding of tumor cells to cytotoxic(More)
Galectin-9 and galectin-8, members of beta-galactoside-binding animal lectin family, are promising agents for the treatment of immune-related and neoplastic diseases. The proteins consist of two carbohydrate recognition domains joined by a linker peptide, which is highly susceptible to proteolysis. To increase protease resistance, we prepared mutant(More)

Thirty-four patients with early relapsing-remitting multiple sclerosis (RRMS) were studied to clarify the differences in chemokine receptor usage by blood and cerebrospinal fluid (CSF) lymphocytes relevant to the pathogenesis of MS. A total of 45 examinations (33 active and 12 inactive stages) revealed that circulating CD4+CXCR3+ T helper 1 (Th1) cells were(More)
To determine the immunological effects of high-dose intravenous methylprednisolone (IVMP) and elucidate immune measurements used for evaluation of its therapeutic effect, we analyzed lymphocyte subsets and humoral immune parameters in peripheral blood and cerebrospinal fluid (CSF) samples, before and within 2 weeks of treatment during 19 acute exacerbations(More)
5'-Deoxy-5-fluorouridine (5'-DFUR) is one of the oral fluoropyrimidines widely used in the treatment of gastric, colorectal and breast cancers in Japan. 5'-DFUR is converted to 5-fluorouracil by pyrimidine nucleoside phosphorylase in the tumor. 5'-DFUR has toxic effects on the intestine and may cause severe diarrhea.(More)
OBJECTIVE The authors compare and characterize the changes in chemosensitivity between the original tumors before chemotherapy and recurrent tumors after responses. SUMMARY BACKGROUND DATA The drug resistance in clinical chemotherapy appears to be different from that in experimental chemotherapy, and the profile and mechanisms of clinical drug resistance(More)
