Rationale. Previous studies have shown that buspirone, a partial 5-HT1A receptor agonist, produces antinociceptive effects in rats and mice; Ca2+ plays a critical role as a second messenger in mediating nociceptive transmission. 5-HT1A receptors have been proven to be coupled functionally with various types of Ca2+ channels in neurons, including N-, P/Q-,(More)
beta-Escin, the major active compound in extracts of the horse chestnut Aesculus hippocastanum seed, has shown clinically significant activity in chronic venous insufficiency (CVI). Our previous studies had shown that beta-escin sodium inhibited angiogenesis in chick chorioallantoic membrane (CAM) and in aortic disk assay. In this study, we explored the(More)
Non-traditional CD4+CD25–CD69+ T cells were found to be involved in disease progression in tumor-bearing mouse models and cancer patients recently. We attempted to define whether this subset of T cells were related to leukemia relapse after allogeneic hematopoietic cell transplantation (allo-HSCT). The frequency of CD4+CD25–CD69+ T cells among the CD4+ T(More)
AIM To investigate the involvement of L-type Ca(2+) channels in antinociceptive action induced by the 5-HT precursor, 5-hydroxytryptophan (5-HTP). METHODS Female Kunming mice were treated with either 5-HTP (20-80 mg/kg, ip) alone, or the combination of 5-HTP and fluoxetine (2-8 mg/kg, ip), pargyline (15-60 mg/kg, ip), nimodipine (2.5-10 mg/kg, ip),(More)
