AIM:To explore the serum levels of certain adhesion molecules and its significance in acute coronary syndrome(ACS). METHODS:The subjects included 40 patients with acute myocardial infarction(AMI) and 40 patients with unstable angina pectoris (UAP). Among the 80 patients, 60 patients accepted a follow-up 4 months. At the same time we selected 40 controls from people who attended a routine health check in the university. Serum levels of E-selectin, sICAM-1, sVCAM-1 were measured by ELISA.RESULTS:Serum levels of E-selectin, sICAM-1, sVCAM-1 were significantly higher in the ACS group(AMI or UAP) than in the control group. Four months later, the levels of E-selectin, sICAM-1 became significantly lower in the follow-up group than in the ACS group, while sVCAM-1 showed no significant difference. CONCLUSION:Serum levels of E-selectin, sICAM-1 may have certain diagnostic value for ACS, and can be a useful marker reflecting the stability of the disease.  相似文献   

Detection of the Defoliating Pathotype of Verticillium dahliae in Infected Olive Plants by Nested PCR   总被引：2，自引：0，他引：2

Spread of Verticillium wilt into newly established olive orchards in Andalucía, southern Spain, has caused concern in the olive industry in the region. This spread may result from use of Verticillium dahliae-infected planting material, which can extend distribution of the highly virulent, defoliating (D) pathotype of V. dahliae to new areas. In this study, a molecular diagnostic method for the early in planta detection of D V. dahliae was developed, aimed especially at nursery-produced olive plants. For this purpose, new primers for nested PCR were designed by sequencing a 992-bp RAPD marker of the D pathotype. The use of the specific primers and different nested-PCR protocols allowed the detection of V. dahliae pathotype D DNA in infected root and stem tissues of young olive plants. Detection of the pathogen was effective from the very earliest moments following inoculation of olive plants with a V. dahliae pathotype D conidia suspension as well as in inoculated, though symptomless, plants.  相似文献

Identification ofTomato Mottle Taino Begomovirus strains in Cuban potato fields     

Marlene Cordero  Pedro L. Ramos  Lester Hernández  Ana I. Fernández  Ana L. Echemendía  Rudy Peral  Gloria González  Daniel García  Surey Valdés  Ana Estévez  Keren Hernández 《Phytoparasitica》2003,31(5):478-489

The presence of a begomovirus in potato plants with yellow mottle symptoms was determined for the first time in Cuba. The incidence of typical begomovirus-like symptoms in potato plants in some regions of Havana province (Güira de Melena, San José de las Lajas, Güines and Boyeros) during the growing seasons from 1992 to 1998 was in general low. However, in some cultivars belonging to the National Program for Potato Genetic Improvement, the incidence reached 100%. Yield losses, determined in 1992 and 1994, ranged as high as 19% to 56.33% depending on the cultivar. Characterization of the causal agent was done by light microscopy, host range (graft and mechanical transmission), DNA hybridizations, polymerase chain reaction, and restriction fragment length polymorphism analysis. Nucleotide sequence of the amplified fragments revealed the presence ofTomato mottle Taino virus. The virus was transmittedvia tubers and has been detected in mixed infections withPotato virus X and withPotato leaf roll virus. http://www.phytoparasitica.org posting Oct. 20, 2003.

 测定了土壤干旱条件下矮生狗牙根、沟叶结缕草和地毯草相对含水量和相对电导率的变化。结果表明，矮生狗牙根的耐旱性较强，沟叶结缕草次之，而地毯草对干旱敏感。干旱胁迫下，地毯草积累脯氨酸最多，沟叶结缕草次之，矮生狗牙根最少，草坪草的脯氨酸的积累与耐旱性呈负相关。地毯草超氧化物歧化酶(SOD)活性持续升高，过氧化氢酶(CAT)活性在短暂升高后降低，过氧化物酶(POD)活性降低；矮生狗牙根和沟叶结缕草的SOD活性先升后降，CAT和POD活性则维持较高水平，表明草坪草的耐旱性与抗氧化酶活性有关。  相似文献
