- Effects of bovine platelet vascular permeability factor on the polymorphonuclear leukocyte-depleted or antihistamine-pretreated rabbits.
抄録
Effects of bovine platelet α-granule acid extract (BPAE) on vascular permeability were examined in the rabbits subjected to either depletion of polymorphonuclear (PMN) leukocytes by nitrogen mustard (nitrogen mustard-N-oxide hydrochloride, 20-40mg/Kg, i. v.) or pretreatments with histamine antagonists of H1-(chlorpheniramine maleate, 10mg/Kg, i. p.) and H2-receptors (cimetidine, 50mg/Kg, i. v.). Increase in vascular permeability due to BPAE (0.1ml of 50 or 250μg/ml) was evaluated by leaked 125I-albumin (30μCi, i. v.). and its activity was correlated with fine structures of the reaction. Simultaneously, inflammatory cell infiltration occurred in the vascular wall as early as 3-5 minutes. The vascular permeability activity was gradually increased during the observation periods, 1 minute- 3 hours. On the other hand, effects of BPAE on the vascular permeability in rabbits were strongly inhibited by depletion of PMN leukocytes, but not effectively inhibited by pretreatment with the histamine H1- and H2-receptor antagonists.<br>In conclusion, it is confirmed that the vascular permeability factor is present in BPAE as has been described in human platelets. Furthermore, it is suggested that BPAE plays a role in the vascular permeability response as a PMN leukocyte-dependent mediator.
