摘要
将ＰＤ＿（２５）－Ｖ＿（５０）做为支气管激发试验的判定指标，与ＰＤ＿（２０）－ＦＥＶ＿１比较分析，两者呈高度显著直线相关。做为支气管哮喘的诊断参考指标，ＰＤ＿（２５）－Ｖ＿（５０）比ＰＤ＿（２０）－ＦＥＶ＿１更为敏感。其特异性及阳性率高，假阳性及假阴性率较４氏。以ＰＤ＿（２５）－Ｖ＿（５０）做为判定指标，可缩短支气管激发试验过程，减少吸入组织胺的累积量，避免其不良反应出现。
D_(25)-V_(50) as a judgement of bronchial provocationtest was compared with PD_(20)-FEV_1.Both PD_(25)-V_(50)and PD_(220)-FEV_1 showed linear correlation,but PD_(20)-V_(50) was more sensitive than PD_(20)-FEV_1 for the diagno-sis of bronchial asthma, and had higher specificity andsensetivity,and lower false-negative and false-posi-tiverate. Moreover PD_(25)-V_(50) provided the advantagesof shorter period of histamine provocation and lowerdose of inhaled histamine.so that avoided the side ef-fects of higher dose of histamine.
