Effects of Lactobacillus casei on Hematology and Blood Chemistry in Normal and Burned Mice

Effects of the bacterial immunostimulant, Lactobacillus casei YIT 0003 (viable), on hematology and blood chemistry in normal and full thickness burned mice were studied. The white blood cell counts in normal and burned mice pretreated with L. casei cells at an early period after the intraperitoneal or subcutaneous administration of the cells were higher than in untreated animals. Significant increases in the population of neutrophils occurred in both groups of mice, at this period. On the other hand, L. casei cells did not affect red blood cell counts, platelet counts, plasma components, enzyme activities and electrolytes

The visible light responsive TiO2 thin film photocatalysts were prepared by applying a dip-coating process, for which the coating solution was prepared using titanium tetraisopropoxide as a source material and different organic solvents. The nitrogen was doped to the obtained TiO2 thin film during the calcination process as an agent for visible light response. The surface morphology was analyzed by AFM and FE-SEM. Nitrogen state in the lattice and crystalline stricture were measured by XPS and XRD, respectively. Photocatalytic decomposition activity of methylene blue on the films was also measured under visible light irradiation using the light emitting diodes

Regulatory B Cells (B10 cells) and Regulatory T Cells Have Independent Roles in Controlling EAE Initiation and Late-Phase Immunopathogenesis

Experimental autoimmune encephalomyelitis (EAE) is a T lymphocyte-mediated autoimmune disease of the CNS. Significant roles for B cells and a rare IL-10-producing CD1dhighCD5+ regulatory B cell subset (B10 cells) have been identified during the initiation and progression of EAE. Whether and how the regulatory functions of B10 cells and FoxP3+ T regulatory cells (Tregs) overlap or influence EAE immunopathogenesis independently has remained unanswered. This study demonstrates that the number of endogenous or adoptively transferred B10 cells directly influenced EAE pathogenesis through their production of IL-10. B10 cell numbers expanded quickly within the spleen, but not CNS following myelin oligodendrocyte glycoprotein35-55 immunization, which paralleled B10 cell regulation of disease initiation. The adoptive transfer of myelin oligodendrocyte glycoprotein33-35-sensitized B10 cells into wild-type mice reduced EAE initiation dramatically. However, B10 cells did not suppress ongoing EAE disease. Rather, Treg numbers expanded significantly within the CNS during disease progression, which paralleled their negative regulation of late-phase disease. Likewise, the preferential depletion of B10 cells in vivo during disease initiation enhanced EAE pathogenesis, whereas Treg depletion enhanced late-phase disease. B10 cells did not regulate T cell proliferation during in vitro assays, but significantly altered CD4+ T cell IFN-γ and TNF-α production. Furthermore, B10 cells downregulated the ability of dendritic cells to act as APCs and thereby indirectly modulated T cell proliferation. Thus, B10 cells predominantly control disease initiation, whereas Tregs reciprocally inhibit late-phase disease, with overlapping B10 cell and Treg functions shaping the normal course of EAE immunopathogenesis.

Short-term clinicopathological outcome of neoadjuvant chemohormonal therapy comprising complete androgen blockade, followed by treatment with docetaxel and estramustine phosphate before radical prostatectomy in Japanese patients with high-risk localized prostate cancer

<p>Abstract</p> <p>Background</p> <p>To assess the outcome of neoadjuvant chemohormonal therapy comprising complete androgen blockade followed by treatment with docetaxel and estramustine phosphate before radical prostatectomy in Japanese patients with a high risk of localized prostate cancer (PCa).</p> <p>Methods</p> <p>Complete androgen blockade followed by 6 cycles of docetaxel (30 mg/m²) with estramustine phosphate (560 mg) were given to 18 PCa patients before radical prostatectomy. Subsequently, the clinical and pathological outcomes were analyzed.</p> <p>Results</p> <p>No patients had severe adverse events during chemohormonal therapy, and hence they were treated with radical prostatectomy. Two patients (11.1%) achieved pathological complete response. Surgical margins were negative in all patients. At a median follow-up of 18 months, 14 patients (77.8%) were disease-free without PSA recurrence. All 4 patients with PSA recurrence had pathologic T3b or T4 disease and 3 of these 4 patients had pathologic N1 disease.</p> <p>Conclusion</p> <p>We found that neoadjuvant chemohormonal therapy with complete androgen blockade followed by treatment with docetaxel and estramustine phosphate before radical prostatectomy was safe, feasible, and associated with favorable pathological outcomes in patients with a high risk of localized PCa.</p

Irinotecan Plus Mitomycin C as Second-Line Chemotherapy for Advanced Gastric Cancer Resistant to Fluoropyrimidine and Cisplatin: A Retrospective Study

Background. S-1 plus cisplatin has been established to be standard first-line chemotherapy for advanced gastric cancer in Japan. The optimal second-line treatment refractory to S-1 plus cisplatin remains unclear. Methods. We retrospectively studied the efficacy, toxicity, and survival of irinotecan plus mitomycin C in patients with advanced gastric cancer refractory to a fluoropyrimidine plus cisplatin. Results. Twenty-four patients were studied. Prior chemotherapy was S-1 plus cisplatin in 15 patients, S-1 plus cisplatin and docetaxel in 8, and 5-fluorouracil plus cisplatin with radiotherapy in 1. The overall response rate was 17.4%. The median overall survival was 8.6 months, and the median progression-free survival was 3.6 months. Grade 3 or 4 toxicities included leukopenia (33%), neutropenia (50%), anemia (33%), thrombocytopenia (4%), anorexia (13%), diarrhea (4%), and febrile neutropenia (13%). Conclusion. A combination of irinotecan and mitomycin C is potentially effective in patients with advanced gastric cancer refractory to a fluoropyrimidine plus cisplatin

Elevated Serum BAFF Levels in Patients with Localized Scleroderma in contrast to other organ-specific autoimmune diseases

Serum levels of B-cell activating factor belonging to the tumor necrosis factor family (BAFF), a potent B-cell survival factor, are elevated in patients with systemic autoimmune diseases, such as systemic lupus erythematosus (SLE), rheumatoid arthritis and systemic sclerosis (SSc). The objective of this study was to determine serum BAFF levels and relate the results to the clinical features in patients with organ-specific autoimmune diseases of the skin, such as localized scleroderma and autoimmune bullous diseases. Serum BAFF levels were examined by enzyme-linked immunosorbent assay in 44 patients with localized scleroderma, 20 with pemphigus vulgaris/pemphigus foliaceus, 20 with bullous pemphigoid and 30 healthy controls. Twenty patients with SSc and 20 with SLE were also examined as disease controls. Serum BAFF levels were elevated in localized scleroderma patients compared with healthy controls. Concerning localized scleroderma subgroups, patients with generalized morphea, the severest form of localized scleroderma, had higher serum BAFF levels than linear scleroderma or morphea patients. The BAFF levels of generalized morphea were comparable with those of SSc or SLE. Furthermore, serum BAFF levels correlated positively with antihistone antibody levels and the severity of skin lesion as well as the number of skin lesions. By contrast, serum BAFF levels were not significantly elevated in patients with pemphigus or pemphigoid. These results suggest that BAFF may be contributing to autoimmunity and disease development in localized scleroderma. © 2007 The Authors Journal compilation © 2007 Blackwell Munksgaard
