The effects of corticosterone after binding to 5-HT1A and 5-HT2 receptors were studied in rats. Binding of [3H]8-hydroxy-2-(di-n-propylamino) tetralin (8-OH-DPAT) to 5-HT1A receptors in the hippocampus decreased 24 h after both acute and chronic (14 day) administration of CORT (50 mg/kg, s.c.). Chronic, but not acute, CORT treatment increased [3H]ketanserin(More)
We have examined the levels of interleukin-6 (IL-6) in plasma and supernatants of peripheral blood mononuclear cells (PBMC) from patients with Behçet's disease and healthy controls using a sensitive enzyme-linked immunosorbent assay (ELISA). Plasma IL-6 level was not detected in any subjects. The IL-6 concentrations in culture supernatants of patients with(More)
Paget's disease is a skin cancer characterized by characteristic (Paget) cells scattered in the epidermis. Although its prognosis is generally favorable with surgical resection, the clinical outcome turns unfavorable in cases with recurrence and metastasis. Therefore, establishment of effective therapeutic regimens is required for advanced Paget's disease.(More)
We studied the effects of chronic forced swim stress on 5-HT2 receptors and beta-adrenoceptors in the rat frontal cortex. The number of 5-HT2 receptors was increased immediately after the last chronic stress, but not after an acute stress. In vivo, the number of wet-dog shakes induced by a 5-HT2 receptor agonist,(More)
Since August of 1988, we have treated seven CTCL patients with extracorporeal photochemotherapy, including two with tumor-stage mycosis fungoides (MF) showing mucinous degeneration, two with plaque-stage MF, and two with erythrodermatous MF. One was withdrawn just after the first trial. For each patient, the phenotypes of peripheral blood lymphocytes were(More)
We investigated the effects of propyl-beta-carboline-3-carboxylate (beta-CCP) on learning and memory tasks in a passive avoidance test in mice to clarify whether beta-CCP is an agonist or antagonist at benzodiazepine (BZP) receptors. At doses up to 10 mg/kg i.v., beta-CCP had no effect on mice in the passive avoidance test. Diazepam impaired passive(More)
AP159 [N-cyclohexyl-1,2,3,4-tetrahydrobenzo(b)thieno(2,3c)pyridine]-3- carboamide,hydrochloride) showed clear anti-conflict activity in rats in the absence of effects on muscle relaxation, potentiation of anesthesia (in mice) or anticonvulsant activity (in mice). This anti-conflict effect was antagonized by treatment with Ro15-1788. By contrast with the(More)
An important disease entity distinct from cutaneous T-cell lymphoma (CTCL) in Japan is adult T-cell leukemia/lymphoma (ATL), which usually shows the same phenotype as CTCL, i.e., a helper/inducer T-cell phenotype (CD4+CD8-), and usually involves the skin. Clinically, both CTCL and ATL are heterogeneous in nature. In this study, we demonstrated differences(More)
We studied the expression of three cell proliferation-associated antigens: DNA polymerase alpha, Ki-67 antigen, and transferrin receptor, in 35 T-cell lymphomas of nodal origin (T-NL) and 40 cutaneous T-cell lymphomas (CTCL). Immunohistochemical staining was carried out on frozen tissue sections of these specimens using three monoclonal antibodies, DAKO-PC,(More)
