Prostaglandin E2 (PGE2) and the cytokines interleukin (IL) 1a and tumor necrosis factor (TNF)a increase bone resorption in vivo, but the effect of these agents on osteoclastic bone resorption has never been studied in an in vitro human system. Our recently described human bone marrow culture system, in which osteoclasts are generated (vitronectin and calcitonin receptor-positive cells which res...

Background: There are many reports regarding to effects of Granulocyte colony-stimulating factor (G-CSF) and stem cell factor (SCF)alone in liver repair .But conflicting data have been reported regarding the role of growth factors such as G-CSF and SCF in the liver regeneration system. Also, there is not such data regarding to effects of co-administration both of G-CSF and SCF in the liver dama...

Haemophilus influenzae type b (Hib) and 7-valent pneumococcal (PCV7) vaccines both became recommended in Japan in 2010. In this study, cytokine production was investigated in peripheral blood mononuclear cells (PBMCs) cultures stimulated with diphtheria and tetanus toxoids combined with acellular pertussis vaccine (DPT), Hib, and PCV7 separately or concurrent different combinations, all as fina...

BACKGROUND Antineutrophil cytoplasmic autoantibody (ANCA) directed against myeloperoxidase (MPO), a diagnostic criterion in MPO-ANCA-associated vasculitis (MPO-AAV), does not always correlate with disease activity. Here, we detected autoantibodies against moesin, which was located on the surface of stimulated endothelial cells, in the serum of patients. METHODS The anti-moesin autoantibody ti...

We have used a combination of hematopoietic growth factors to induce in vitro granulocytic maturation. A fraction of marrow cells enriched for hematopoietic progenitor cells (CD34+, HLA-DR+) was isolated from normal human bone marrow by monoclonal antibody staining and fluorescence-activated cell sorting. Cells were cultured in a suspension system for 3 days in the presence of stem cell factor ...

Studies have shown that diterpenes have anti-inflammatory and redox-protective pharmacological activities. The present study aimed to investigate the anti-inflammatory properties of phytol, a diterpene alcohol, in a mouse model of acute inflammation, and phytol effect on leukocyte recruitment, cytokines levels, and oxidative stress. The anti-inflammatory activities of phytol were assessed by me...

Gastrointestinal toxicity is one of the most serious side effects in the methotrexate (MTX) treatment. This study was designed to investigate whether ellagic acid (EA) and/or pumpkin seed oil (PSO) had a protective effect on MTX-induced small intestine damage. Forty albino rats were randomized into five groups of 8 rats each. Group I served as a normal control group. In Group II, MTX was admini...

Nonsteroidal anti-inflammatory drugs (NSAIDs) can induce intestinal mucosal damage, but the underlying mechanisms remain poorly understood. The present study investigated the effects of celecoxib, etoricoxib, indomethacin, and diclofenac on small bowel integrity in rats. Male rats were treated orally with test drugs for 14 days. Animals were processed for assessment of blood hemoglobin levels a...
