This study was conducted to determine the effect of clarithromycin (CAM) on the bioavailability of cyclosporin (CYA) in rats, and to compare its effect with that of erythromycin (EM). The area under the blood CYA concentration-time curve (AUCi.v.) values after intravenous administration of CYA (2 mg/kg) in combination with CAM or EM (100 mg/kg, p.o.) were(More)
1. Mast cells and basophils are believed to trigger allergic reactions and anaphylaxis. They rapidly release histamine (H), a typical mediator of inflammation, in response to antigens. In the mouse, platelets contain much 5-hydroxytryptamine (5HT), an additional inflammatory mediator, while human platelets contain both H and 5HT. Here, we examined the(More)
An analogue of sendide, [DTrp7]sendide, was newly synthetized and evaluated as a putative NK1 receptor antagonist in a mouse behavioural test. Effects of [DTrp7]sendide on the scratching, biting and licking response induced by substance P (SP), neurokinin A (NK A) and neurokinin B (NK B) was studied after intrathecal injections. When administered(More)
In experimental animals, the lung rapidly removes intravenously injected 5-hydroxytryptamine (5HT), but the mechanism underlying this pulmonary 5HT removal (P-5HT-R) and the responsible cells remains unclear. 5HT reportedly induces rapid pulmonary platelet accumulation (P-PLT-A). Here, we examined the relationship between P-5HT-R and P-PLT-A in mice by(More)
