A polarographic method for the quantitative analysis of urine putrescine and p-wave substance was introduced and its significance in malignant tumor diagnosis explored. A characteristic polarographic wave at -1.3-1.35V (p-wave ) identical with that of putrescine was observed. The substance(s ) responsible for this characteristic wave was tentatively called p-wave substance, the nature of which was not yet clear.With this technique a comparative study was made on the urine analysis among 60 normal subjects, 105...

A polarographic method for the quantitative analysis of urine putrescine and p-wave substance was introduced and its significance in malignant tumor diagnosis explored. A characteristic polarographic wave at -1.3-1.35V (p-wave ) identical with that of putrescine was observed. The substance(s ) responsible for this characteristic wave was tentatively called p-wave substance, the nature of which was not yet clear.With this technique a comparative study was made on the urine analysis among 60 normal subjects, 105 patients with various cancers, 22 patients with benign tumors and 14 patients with non-tumor diseases, with mean values±SD of 20.4±4.22, 90.1±5.66, 35.8±6.82 and 50.2±11.1 respectively. Evidently there was a marked elevation of p-wave substance in the urine of cancer patients.If we take 50 as an upper limit of the normal value, positive results were found in 82.4% of patients with esophageal cancer, 80% of patients with lung cancer and 71.0% of patients with stomach cancer. However, only 6.6% and 18.1% positive results were found respectively in normal subjects and patients with benign tumors.The possible significance of this technique in cancer diagnosis was briefly discussed.

恶性肿瘤病人尿中多胺排出量增多,腐胺尤甚。疗效显著者,尿中腐胺也明显下降。在小鼠诱发胃癌试验时,发现胃癌前尿内腐胺排出量即已增高。有人认为尿中腐胺量增多可反映细胞的增殖率。目前腐胺测定法弊端尚多。鉴于极谱,特别是催化极谱的灵敏度高,准确性强,便于测定有机物质。已有精胺、精脒极谱分析的报告,尚未见腐胺极说分析的报道。本文试用示波极谱定量分析腐胺,探讨其用于癌症诊断的可能性。

An innovation of double antibody sandwich enzyme immunoassay for the determination of human IgD was reported. Optimal conditions for best results were investigated. Results suggested that this method was as reliable as the classical Mancini radial immunodiffusion method and the sensitivity of the former was approximately 3,000 times higher than that of the latter: i.e., even an amount of 1.5ng/ml of IgD could be detected. This assay might be used for the determination of human IgD in adult or cord sera and cerebro-spinal...

An innovation of double antibody sandwich enzyme immunoassay for the determination of human IgD was reported. Optimal conditions for best results were investigated. Results suggested that this method was as reliable as the classical Mancini radial immunodiffusion method and the sensitivity of the former was approximately 3,000 times higher than that of the latter: i.e., even an amount of 1.5ng/ml of IgD could be detected. This assay might be used for the determination of human IgD in adult or cord sera and cerebro-spinal fluid ( 1,700, 150 and 61 samples ) and was much simpler and faster than radioimmunoassay and required no special protection.

Zinc and copper in blood serum could be determined simutaneously by anodic stripping voltammetry with, a mercury-coated silver electrode. The amount of serum needed was only as small as 0.1 ml. After the digestion process by using perchloric acid at 250°-260℃, 5ml ammonia(0.6M)-ammonium acetate (0.1 M) solution (pH 9.0-9.6)were added. Nitrogen gas was passed through for stirring and deaeration.The measurements of zinc and copper were completed by plating for 30 sec at -1.6V (vs silver/silver cholride electrode)....

Zinc and copper in blood serum could be determined simutaneously by anodic stripping voltammetry with, a mercury-coated silver electrode. The amount of serum needed was only as small as 0.1 ml. After the digestion process by using perchloric acid at 250°-260℃, 5ml ammonia(0.6M)-ammonium acetate (0.1 M) solution (pH 9.0-9.6)were added. Nitrogen gas was passed through for stirring and deaeration.The measurements of zinc and copper were completed by plating for 30 sec at -1.6V (vs silver/silver cholride electrode). The derivative I vs E curve was recorded from -1.6 V to -0.2V at scan rate of 100mv/sec. Stripping peaks of zinc and copper occurred at -1.1 V and -0.4V, respectively.This method proved itself a better reproducibility. Calibration curves of zino and copper in the range of 0.06μg to 0.3μg showed linear relation. The recovery rate of 0.08μg zinc was 90% and copper, 104%.Our studies showed that interference due to formation of copper-zinc intermetal-lic on the mercury-coated silver electrode was eliminated. In 0.1ml serum, iron (Ⅲ), lead and cadmium did not affect the analytical results.By using this simple rapid method, the concentration of zinc and copper in blood serum of 261 healthy persons were determined. The results are: Zino 137μg/100ml serum, copper 107μg/100ml serum (mean value), zinc/ copper ratio: 1.32/1.

本文研究了用银棒汞膜电极阳极溶出伏安法同时测定人血清中的微量锌和铜,血清取样量仅需0.1ml,经高氯酸消化处理后,在5mlNH_3(0.6M)一NH_4OAC(0.1M)辅助电解质中,置电位于-1.6V处电积后溶出,可同时记录锌和铜的溶出峰高。本法可排除锌和铜的相互干扰,具有较好的重现性和准确性,为研究微量元素Zn/Cu比值与人体健康的关系,提供快速、简便的分析方法。
