GDM对球类系男生Hb、WBC数及大强度训练后upr的影响

本研究以上海体院球类系６０名男生作为实验对象，将他们随机分为实验组和对照组，两组各３０人．实验组饮用ＧＤＭ饮料，对照组饮用安慰剂．分别测定服用前后Ｈｂ，ＷＢＣ数，并在服用前后进行相同大强度训练后测定尿蛋白含量．结果表明：试验组服用ＧＤＭ四周后Ｈｂ明显升高，ＷＢＣ数量有所提高，而且等大强度运动后尿蛋白净值明显下降；而服用安慰剂组，四周后Ｈｂ及ＷＢＣ数无显著性差异．说明ＧＤＭ有助于球类系男生运动能力的提高，同时能够增强机体免疫能力和抗疲劳抗负荷能力．     

家兔膀胱动脉的解剖学研究

用血管铸型和透明方法观察了家兔膀胱的血供情况。膀胱动脉主要起自脐动脉，沿膀胱侧缘行向膀胱顶，沿途发出１～４支基本对称的分支分布于膀胱前面，两侧膀胱动脉的分支在其表面有吻合现象。膀胱动脉及其分支均呈不同程度的弯曲或弹簧状，可能是适应膀胱生理性增大的结构基础。     

Preferential excretion of glycated albumin in C57BL-Ks-J mice: Effects of diabetes

Urinary excretion of glycated albumin was quantitated in genetically hyperglycemic mice (C57BL-Ks-J, db/db mice), a model for non-insulin-dependent diabetes mellitus, and compared with their non-diabetic littermates. The data indicated a preferential excretion of glycated albumin in non-diabetic mice. This phenomenon of editing of glycated albumin is decreased significantly in diabetic mice. Quantitative measurements of overall excretion of glycated albumin suggested that the loss of editing in diabetic mice is due to the dilution of glycated albumin by the unmodified albumin which is excreted in large amounts in diabetic mice. Therefore, the loss of editing observed in this model resembled the one we characterized in insulin-dependent diabetic humans and a streptozotocin-diabetic rat model³.     

Biomimetic fluorapatite films for conservation of historic calcareous stones

Fluorapatite protective films were prepared on marble substrates using a biomimetic method. By mimicking the mineralization mechanism of enamel, phosphorus and fluorine were introduced on the surface of the marble substrate. In the presence of a biological template, namely collagen, an integrated fluorapatite film was produced and the marble substrate was entirely covered. The prepared fluorapatite films were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy dispersive X-ray (EDX) spectroscopy. The performances of the fluorapatite films were evaluated by color changes, capillary water absorption, and acid resistance tests. The results revealed that the fluorapatite films had good compatibility with the marble substrate; the physical properties such as color and capillary water adsorption of the marble substrates were unchanged. The fluorapatite films also had good acid resistance and were stable even in heavy acid rain.     

用离子色谱法测定人尿中的草酸

本文叙述了一种使用离子色谱技术测定人尿中的草酸的新方法。该方法只需要简单的样品制备:尿样用盐酸酸化,用去离子水按需要稀释,最后通过0.2μm孔径的微孔滤膜过滤就能直接注入离子色谱仪分析。本方法每分析一个尿样仅需10min,在稀释后的尿样中草酸的低检测限为0.1ppm(1.1μmol/l),用标准加入法获得的草酸平均回收率为100.28%。我们使用本方法测定了300多个尿样中的草酸,其线性范围为1～1000ppm,相对标准偏差为4%。本方法可以用于人尿中草酸的直接测定。     

二元羧酸对草酸钙结晶的调控作用

采用双扩散法系统研究了凝胶体系中二元羧酸对尿结石主要成分草酸钙结晶的影响,这些羧酸分别为含有0、1、2个羟基的丁二酸、羟基丁二酸、酒石酸,含有1个氨基的L-天冬氨酸,以及含有双键的顺丁烯二酸、反丁烯二酸．对于丁二酸、羟基丁二酸和酒石酸的研究表明,随着羧酸中羟基数目的增加,抑制一水草酸钙(COM)聚集和诱导二水草酸钙(COD)生成的能力逐渐增强;随着羧酸浓度的增大,抑制COM聚集和诱导COD生成的能力也增强;随着结晶时间的增加,COM晶体钝化程度加深．对L-天冬氨酸、顺丁烯二酸和反丁烯二酸的研究表明,三者影响不明显．
