对51例献血者的测定表明:c-GMP的血浆浓度均值为8.1pmol/ml。其范围由6～12pmol/ml。 对10例具有较重哮喘症状的儿科病人(包括暴喘型肺炎,喘息性支气管炎及支气管哮喘)的观察表明,在哮喘发作期均有血浆cGMP浓度上升。(均超过12pmol/ml)。而在治疗后,则随之恢复正常。其中二例,虽症状消失,但血中c-GMP浓度仍不恢复正 The assay on 51 blood donors showed that the mean plasma concentration of c-GMP was 8.1 pmol / ml. Its range is from 6 to 12 pmol / ml. The observation of 10 pediatric patients with severe asthma symptoms, including asthmatic pneumonia, asthmatic bronchitis and bronchial asthma, showed an increase in plasma cGMP concentrations during both asthma attacks. (All over 12 pmol / ml). After treatment, then returned to normal. Two cases, although the symptoms disappear, but the blood concentration of c-GMP still does not recover positive
