毒理性
为了研究非免疫性接触性荨麻疹(NICU)的机制,研究了阿司匹林(ASA)1克+1克对甲基烟酸酯、二乙基富马酸酯、苯甲酸、肉桂酸、肉桂醛和二甲亚砜接触反应的影响,在21名受试者中进行。通过视觉观察红斑和水肿反应,并使用激光多普勒流量计监测皮肤血流的变化。ASA对所有6种物质的红斑有显著的抑制作用,对除二甲亚砜以外的所有物质的水肿也有抑制作用。这种效果的机制可能是由于ASA对前列腺素生物合成的抑制影响。因此,为了避免假阴性测试结果,在NICU测试期间不应使用非甾体抗炎药。
To investigate the mechanisms of non-immunologic contact urticaria (NICU), the effects of 1g + 1g of acetylsalicylic acid (ASA) on contact reactions to methyl nicotinate, diethyl fumarate, benzoic acid, cinnamic acid, cinnamic aldehyde and dimethyl sulfoxide were studied in 21 test subjects. Erythema and edema reactions were observed visually, and the changes in the skin blood flow were monitored using laser-Doppler flowmetry. ASA had a significant inhibitory effect on erythema from all 6 agents and also on edema from all substances except dimethyl sulfoxide. The mechanism of the effect may be a result of the inhibitory influence of ASA on prostaglandin bioformation. Thus, to avoid false negative test results, non-steroidal anti-inflammatory drugs should not be used during NICU tests.
