研究了显色时间和显色温度对多酚总量检测的影响，实验证明，显色温度和显色时间对绿原酸标准溶液的吸光度影响较大，而对烟草样品溶液影响较小。

Result:①out of 25 patients,17 exhibited myeloma-related bone lesions on radionuclide imaging,the positive rate was 68.0%,ribs and spine were involved most frequently,162 lesions showed high uptake of radionuclide,the lesions lied in ribs appeared as strings of pearls,and those in sternums and vertebrae showed linear high uptake,the other 4 showed decreased radionuclide uptake.②the positive rate on radiography was 68.0%(17/25),which was the same as that on radionuclide imaging,the patterns were osteoporosis,pathological fracture,osteolysis or two or two and above of these appearances, radiography detected more abnormalities than radionuclide imaging in identical sites(162 versus 144),but radionuclide imaging detected more lesions than radiography in ribs and sternums.

结果：①25例患者中，骨显像异常17例，阳性率68.0%，肋骨、脊柱最常受累，162处病灶表现为异常放射性聚集，其中，肋骨病灶呈串珠样，胸骨及椎体病变呈扁平状或线状，4处表现为异常放射性减低；②x线片阳性率68.0%（17/25例），与骨显像相同，主要表现为骨质疏松、病理性骨折、骨破坏或呈混合性改变，共同检测的部位中，x线片检出的病灶总数较骨显像多（162和144），但骨显像检出肋骨和胸骨病灶较x线片多。
