旋转强恒磁场对SD大鼠骨骼生长发育及相关激素的影响

目的探讨旋转强恒磁场（RCSMF）对SD大鼠的骨骼生长发育及相关激素的影响，为RCSMF促进人体增高的临床应用奠定基础。方法取25日龄的SD大鼠置RCSMF下，1．5h／d。每5天取血检测大鼠生长激素（GH）、类胰岛素生长因子（IGF-Ⅰ）、雌激素（E2）等与骨骼发育相关的激素，同时测量每组大鼠的身长、体重和尾长，并用骨形态计量学方法研究RCSMF对大鼠骨组织形态学和动态学参数的影响。结果RCSMF处理后大鼠的身长[实验组（25．28±0．41）cm。对照组（24．05±0．35）cm；P〈0．01]、体重[实验组（445．90±16．88）g，对照组（382．22±12．78）g；P〈0．01]、胫骨长[实验组（3．89±0．13）cm，对照组（3．66±0．10）cm；P〈0．01]和股骨长[实验组（3．65±0．08）cm，对照组（3．51±0．06）cm；P〈0．01]，上述多项参数以及骨骺板等相关形态计量学数据实验组明显高于对照组。回归分析身长与相关激素的关系显示：大鼠身长与GH、IGF—I和E2有显著相关性。结论RCSMF有促进骨骼生长发育的作用，其作用机理是通过刺激与骨骼生长发育相关激素的生成、释放，并影响软骨细胞的增殖功能来完成的。     

正常足月孕妇骨矿物质含量的测定

用单光子吸收法对足月孕妇尺、桡骨骨矿物质含量（ＢＭＣ）、骨面密度（ＢＭＣ／ＢＷ）进行测定及作血清钙、磷的生化测定。结果显示：足月孕妇的尺、桡骨骨矿物质含量、骨面密度明显低于同年龄组的未孕妇女。主要因为妊娠胎儿的骨胳生长发育，需要孕妇向胎儿输送大量的钙离子，若母亲对钙摄入不足或吸收不良，则造成孕妇的骨矿物质含量降低，骨质疏松；而孕妇血清钙、磷降低不明显。

Lead in finger-bone analysed in vivo in active and retired lead workers

In 75 active lead workers the median lead level in finger-bone (bone-Pb), as determined in vivo by an X-ray fluorescence method, was 43 micrograms/g (range less than 20-122). In 32 retired workers the median level was even higher, 59 micrograms/g (range less than 20-135), which indicates a slow turnover rate of lead in finger-bone. This was confirmed in 18 of the "active" workers, in whom bone-Pb was studied in connection with an exposure-free period. In spite of a significant decrease in blood-lead levels (B-Pb), no systematic change of bone-Pb occurred. There was an increase of bone-Pb with time of employment, but with a large interindividual variation. No association was found between bone-Pb and present B-Pb in the active lead workers. However, in the retired ones, B-Pb rose with increasing bone-Pb. The bone-lead pool thus causes an "internal" lead exposure.

The role of radiography, computed tomography and bone scanning in prostatic cancer

This report reviews the roles of conventional radiography, computerized axial tomography, and nuclear bone scanning in the diagnosis, staging, follow-up, and management of prostatic cancer. Computed tomography (CT) offers great promise for the better definition of the extent of the primary tumor of prostatic cancer. It contributes positively to the planning of radiation therapy portals in the treatment of localized disease. By means of bipedal lymphangiography and CT scanning, pelvic and periaortic lymphadenopathy may be detected more often than was previously possible without staging pelvic lymphadenectomy, which can be reserved for the discovery of microscopic disease. Soft-tissue metastases that are located deep within the body cavities can now be measured accurately by CT scanning, as can their response to therapy. Skeletal metastases, the most common variety in prostatic cancer, can be detected with a high degree of sensitivity by nuclear bone imaging. Serial bone scans are remarkably useful in following the response of osseous deposits to treatment, as well as in detecting relapsing disease. The management of malignant obstruction of the ureters has been greatly facilitated by the application of angiographic techniques to percutaneous nephrostomy performed under fluoroscopic control.
