[问题59答案]:a～d [注解] 支气管哮喘是阻塞性换气障碍的疾患,所以发作时1秒率必然降低,肺泡中P_AO_2减少,因P_ACO_2升高,故动脉血P_aCO_2也升高。严重时呈呼吸性酸中毒状态。病因有外源性和内源性两种,内源性时的中毒,感染和精神因素不易证实过敏原。P-K反应(Prausnitz-Küstner反应)是把患者的血清注射到他人的皮肤内,进而在相同部位注射抗原的方法。是同种的和被动的皮肤过敏症,可了解患者对哪种抗原敏感。此时抗体固定于组织,在此与抗原反应,和γ_1抗体或IgE有关。因而a,b,c,d是正确的。阻断抗体是减敏治疗时阻断抗原产生的抗体。它使r-G抗体升高阻断IgE和抗原的反应。
[Answer 59]: a ~ d [Note] bronchial asthma is a disease of obstructive ventilation disorders, so the onset of 1 second rate will inevitably reduce the alveolar P_AO_2 decreased, due to P_ACO_2 increased, so the arterial blood P_aCO_2 also increased. Severe respiratory acidosis. Etiology has extrinsic and endogenous two, endogenous poisoning, infection and mental factors is not easy to confirm the allergen. The P-K reaction (Prausnitz-Küstner reaction) is a method of injecting the patient’s serum into the skin of another person and injecting the antigen at the same site. Is the same kind and passive skin allergies, which patients can understand the sensitivity of the antigen. At this point the antibody is immobilized to the tissue where it reacts with the antigen and with the γ_1 antibody or IgE. Thus a, b, c, d is correct. Blocking antibodies are antibodies that block the production of antigens when desensitized. It causes an increase in r-G antibodies to block IgE and antigen responses.
