WU Wen  ZHI Xi-mei  LI Dong-feng  LIN Kai  YANG Yan-hong 《园艺学报》2007,23(2):376-378

AIM:To study the relationship between serum insulin-like growth factor- 1 (IGF-1), insulin-like growth factor binding protein-3 (IGFBP-3) levels, bone mineral density(BMD) and bone metabolic markers in postmenopausal women. METHODS:Serum IGF-1, IGFBP-3, osteocalcin(BGP), isomeric C-telopeptide of type I collagen (β-CTX), estradiol(E₂), calcitonin(CT), parathormone(PTH), calcium (Ca), and phosphorus(P) were measured in 90 postmenopausal osteoporosis patients and 70 healthy postmenopausal women. BMD of lumbar vertebra and left femoral neck were determined by dual energy X-ray absorptiometry.RESULTS:BMD of lumbar vertebra and left femoral neck decreased significantly (P<0.01), serum IGF-1, IGFBP-3, E₂, CT and BGP decreased significantly (P<0.01), serum β-CTX and PTH increased significantly in postmenopausal osteoporosis group (P<0.01). There were no significantly differences in serum Ca, P between two groups (P>0.05). BMD of lumbar vertebra and left femoral neck were positively correlated with serum IGF-1, IGFBP-3, E₂, CT and BGP, but negatively correlated with β CTX and PTH. There were no correlation with serum Ca, P and BMD.CONCLUSION:Serum IGF-1, IGFBP-3, E₂, CT, BGP, β-CTX and PTH level were correlated with BMD of lumbar vertebra and left femoral neck. These markers can be one of the valuable evidences for screening osteoporosis in postmenopausal women.  相似文献   

甲壳素等生物制剂对仙客来枯萎病的防治效果及生长促进作用研究     

黄建明  郑志兴  尉文彬  武玉环  曹丽霞 《中国植保导刊》2007,27(10):12-13

对比试验结果表明,甲壳素单独使用、甲壳素与放线菌混合使用、甲壳素与放线菌和枯草杆菌混合使用灌根,对仙客来枯萎病均具有明显的防治效果,仙客来成活率显著提高,其防效与常用化学农药相当。同时对仙客来的生长发育均有促进作用。处理后根的数量、根系的鲜重和干重均有显著增加,并使叶片数增多,冠径增大。此外,单独使用甲壳素还使土壤中放线菌数量明显增加。  相似文献

Serum concentration of S100-B protein in patients during CABG with or without cardiopulmonary bypass     

HONG Feng  PENG Jian-ming  ZHANG Rui-xiang  CHEN Jun-peng 《园艺学报》2007,23(7):1293-1295

AIM: To investigate the mutative law of the serum S100-B protein in patients undergone coronary artery bypass grafting with or without cardiopulmonary bypass (CPB-CABG or non-CPB CABG), and to compare the degree of cerebral injury in patients during CABG between the two different surgical manipulations.METHODS: 30 patients were divided into two groups: CPB-CABG group (group A) and non-CPB CABG group (group B). Every group included 15 patients. Blood from jugular vein was phlebotomized in every patients at the following 8 time points: before operation (OP), after anaesthesia, end of grafting, end of OP, 2 h after OP, 6 h after OP, 12 h after OP and 24 h after OP. The serum concentrations of S100-B protein in the samples were measured.RESULTS: The level of serum S100-B protein increased markedly at the beginning of CABG, and the peak value of group A (2.32 μg/L±0.26 μg/L) was treble higher than that in the patients in group B (0.71 μg/L±0.14 μg/L). The levels of S100-B protein tend to normal level in both groups 24 h after OP. The level of S100-B protein had notable relation with the time of CABG in group A and the manipulative time on the heart in group B.CONCLUSION: The degree of cerebral damage can be valued by investigating the mutative law of the serum S100-B protein in patients undergone CPB-CABG and non-CPB CABG. The non-CPB CABG reduces the degree of cerebral damage and avoids the functional disorder of central nerve.  相似文献

沙棘次生根贮水与根皮层细胞的超微结构研究   总被引：1，自引：0，他引：1  

郭陈刚魏志敏  张吉科贾建明 王新玉 《华北农学报》2007,22(B10):139-142

通过直接测量沙棘次生根鲜质量和吸水后质量以及次生根直径和皮层厚度，并与小叶杨做对照研究了沙棘次生根皮层贮水功能，结果表明，沙棘根系贮水组织主要是沙棘次生根皮层。还用透射电镜观察了沙棘次生根皮层细胞超微结构，结果表明，沙棘次生根皮层细胞的中央液泡化是蓄贮水分的场所，具活力的细胞质环带是水分蓄释的调控中心，庞大的线粒体群是水分蓄释的动力，质膜与胞间层的液泡系与吞噬泡以其表面特有的功能单位为信号调控着水分、物质的胞间交换，细胞中某些不明贮藏物可能起着渗透调节功能。沙棘耐旱的机理是次生根生理贮水，节约用水，耐旱程度与根部蓄水量有关。沙棘是一种生活型的适应旱生植物。  相似文献
