107例颈外动脉结扎术在头面部疾病中的应用

颈外动脉结扎术应用于顽固性鼻衄,外伤性颞浅动脉出血,外伤性上颌骨骨折反复出血,上颌窦新生物反复出血,鼻腔肿瘤术前及鼻咽纤维血管瘤术前等计107例,认为颈外动脉结扎术简单安全、疗效可靠。对顽固性鼻出血施以结扎栓塞疗效更佳;高血压或血管疾患的顽固性鼻衄,早期结扎为好。

学生体质模糊综合评价的探讨

学生体质综合评价离不开评价标准的制定。无论是离差法还是百分数法[1]，其划分等级的中界值是一条清晰的界限．在此线上下的微小变化，就会被判为两个不同的等级。相反，某一年龄组中尽管下限和上限的差值较大，但仍属于一个等级，这显然不够合理。群体评价差异就更大。本文运用模糊综合评价法，选用线段函数为隶属度，取得满意结果。1模型与原理1．且选择因素集体重／身高X1000，mZ一肺活量／体重，。13＝503跑．u4一立定跳远，115一引体向上八m卧起坐，tie＝50mX8往返跑，800m跑（女），1000m跑（男）。1．2评价集V一呼等（VI）．中下…

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.
