Plasma histamine levels were measured in 11 clinically healthy cats and 15 cats with allergic dermatitis. Histamine levels were markedly elevated in 5/15 allergic cats. A calcium ionophore, A23187, stimulates histamine release from feline peripheral blood cells. Immunostaining of blood smears from clinically healthy cats revealed that approximately 10% of eosinophils possessed histamine-containing granules. These results indicate that some peripheral eosinophils in cats contain histamine and can release histamine by appropriate stimulation.
在11只临床健康的猫和15只患有过敏性皮炎的猫中测量了血浆组胺水平。15只过敏性猫中有5只组胺水平显著升高。钙离子载体A23187可刺激猫外周血细胞释放组胺。对临床健康猫的血涂片进行免疫染色显示,约10%的嗜酸性粒细胞含有含组胺的颗粒。这些结果表明,猫的一些外周嗜酸性粒细胞含有组胺,并可通过适当刺激释放组胺。
