    摘要: Even when the specimen contains human granulocyte elastase in the form of a mixture of free elastase with an elastase-inhibitor complex or complexes, the present invention enables the total quantity of elastase in that specimen to be precisely detected. The inhibitor is added to free elastase to convert it into an elastase-inhibitor complex, whereby the quantity of elastase can be measured by immunoassay as the total amount including the previously existing elastase-inhibitor complex. It is possible to precisely measure the total amount of elastase in mucus collected from the cervical canal of a pregnant woman, sputum or a rinsed solution of bronchovesicular lavage in which free elastase is mixed with an elastase-inhibitor complex. It is thus possible to predict and prevent threatened premature delivery, premature delivery or premature rupture of membranes by immunoassay of mucus collected from the cervical canal of a pregnant woman, to make a diagnosis of chronic or repetitive airway infections and pulmonary emphysema based on chronic respiratory diseases by immunoassay of sputum and a rinsed solution of bronchovesicular lavage and to make a diagnosis of urinary tract infections by immunoassay of urine.

    摘要: A method of enzymatically measuring hydrogen peroxide by developing a color with use of 3-methyl-2-benzothiazolinoehydrazone as a coupler and in combination with an oxidative color developing reagent with peroxidase, and a reagent therefor is described. Catalase is added to the 3-methyl-2-benzothiazolinonehydrazone reagent as a stabilizer and the reaction is carried out in the presence of ethylenediaminetetraacetic acid or an analogue thereof. The color developing reaction may be carried out in neutral or weak alkali conditions. A reagent is described which comprises a buffer, 3-methyl-2-benzothiazolinohydrazone, and catalase.
