ABSTRACT
Objective To explore the correlation between myeloperoxidase(MPO) and white blood cell (WBC) and other related numerical values in blood .Methods 50 common patients were randomly selected .The two blood samples in each patient were re-spectively collected by the biochemical tube anticoagulated by heparin sodium and the blood routine tube anticoagulated by ethylene diamine tetraacetic acid kalium(EDTA-K2 ) .Then plasma MPO content and WBC count ,absolute neutrophils count ,percentage of neutrophils ,platelet count in whole blood were detected .The MPO content and the above 4 items of detection results were per-formed the correlation analysis .Results The correlation coefficients(r) between plasma MPO with WBC count ,neutrophils count , percentage of neutrophils and platelet count in whole blood were 0 .253 ,0 .220 ,0 .111 and 0 .133 respectively ,which indicating that no correlation existed between them .Conclusion Blood MPO is mainly derived from polymorphonuclear neutrophils ,but WBC count ,neutrophils count and platelet count in whole blood do not cause the change of the myeloperoxidase content .
ABSTRACT
Objective To understand the water source type,the water supply way and drinking water quality in the pastoral areas in Qinghai Province. Methods One hundred and thirteen water samples in 11 counties were collected in the rainy season in 2006 and the water samples were tested according to the methods in Analytical Methods for Water and Sanitary Standard for Drinking Water Quality (2001),Sanitary Standard for Drinking Water Quality(2001). Results 1 741 231 population were investigated,the population consuming centralized water supply and dispersed water supply were 1 013 283(58.19%) and 727 948(41.8%) respectively. The population of drinking underground water occupied 76.4%,of which,drinking spring water occupied 83.2% and drinking well water occupied 4.6%. The population of drinking ground water occupied 23.6%,of which,drinking river water occupied 53.6%,drinking lake water occupied 0.2%. There were 638 centralized water supply plants,of which,only 11 water plants had complete water treatment. The dispersed water supply was consisted of manpower(84.7%),handpump(9.8%) and machine(5.5%). 51 of 113 water samples were up to standard,the overall eligible rate was 45.1%,of which the eligible rate of ground water was 25.9%,underground water was 51.2%,centralized water supply was 56.8%,dispersed water supply was 15.6%,showed the significant difference(P
