大鼠摄入铝,氟及其不同比例混合物后血和骨中铝氟含量分析

Wistar rats were divided into 8 groups:control, 300 ppm F, 130 ppm F, 300 ppm Al, 1200 ppm Al, 130 ppm Al + 130 ppm F. 300 ppm Al + 300 ppm F and 1200 ppm Al + 300 ppm F. The chemicals were mixed into the standard diet. The animals were fed on the diets for 12 weeks. Contents of F, Al, Ca and P in the blood (or serum) and humerus were determined at the end of 12 weeks. The results showed that the level of F in the blood and bone in the unadulterated F group was increased, especially F in the bone reached a level more than 10 times that of the control. In the 3 mixture groups, blood F and bone F were lowered, while blood F was restored to normal level, but bone F was not nevertheless, the results showed that Al was in antagonism to the absorption of F. In the unadulterated Al groups, blood and bone Al did not parallel with the amount of Al administered. The level of Al in the median Al group was higher than that of the high Al group. Taking the level of blood and bone Al as a measure, when different doses of Al were administered with F, in the low and median dosage of Al, F was in antagonism to Al absorption, but in case of high dosage of Al, F was in potentiation to Al absorption. In all the experimental groups serum P was elevated, but serum Ca was not disturbed. Bone Ca and P were decreased only in the 3 groups with unadulterated F as well as unadulterated and adulterated high dosage of Al. Mechanism of the nonlinearity of Al absorption vs Al dosage, as well as the dual effect of F on the absorption of Al was proposed.

B超在药物流产前后的应用价值探讨

药物流产由于其有效、方便和安全，且疗效明确，已被许多妇女和妇产科医生所接受，但其在应用前适应证的选择及用药后的监测中，B超有着重要的意义。1998年1月-2002年8月，我院对340例早孕需流产、欲选择药物流产者，于用药前后进行B超检查，现报道如下。     

恙虫病立克次体DNA及DNA序列测定

目的:检测39例不明原因发热患者血液中恙虫病立克次体DNA。方法:用NPCR检测恙虫病立克次体DNA,取其DNA提取物进行DNA序列分析。结果:序列分析表明扩增的片段为立克次体DNA片段。39例不明原因发热患者血液用NPCR法检出13例恙虫病立克次体DNA。占不明原因发热患者的33.3%。结论:NPCR法可以快速检出恙虫病立克次体DNA,可用于恙虫病的临床早期诊断。
