不同浓度氢氟酸对大鼠血钙变化的影响

OBJECTIVE: To evaluate the effects of different concentration of hydrofluoric acid (HF) on local skin and calcium level of serum. METHODS: SD rats were divided into two groups which were wounded by 20% and 40% percent of HF respectively. Samples of blood and wound tissue were harvested at different postburn time for the analysis of the calcium level of the serum and histological study. RESULTS: It was found that twenty percent of HF was enough to cause a skin damage, and might bring about fatal hypocalcemia after a prolonged contact. High concentration of HF (40%) could cause deep tissue necrosis within a short time, and result in a fatal hypocalcemia within 24 hour even in the case of a small area injury. CONCLUSION: It is important to treat the patient with HF injury as early as possible. Sufficient calcium must be applied guided by laboratory study in order to prevent the fatal hypocalcemia.     

经尿道电切术的内毒素血症

１９９３年１－８月测定４３例经尿道电切术患者术前、术中血内毒素浓度变化，探讨ＴＵＲ内毒素血症与临床意义。患者男性３９例，女性４例。其中良性前列腺增生１７例，ＢＴＣＣ１９例，膀胱颈口梗塞７例，年龄１７－７５岁，平均５７．１岁。随机选择分为两组，Ⅰ组２１例，仅口服抗生素；Ⅱ组２２例，静脉滴注先锋霉素Ⅵ２ｇ后方实施ＴＵＲ。     

强化大米的营养评价

本实验在大米中强化维生素B_1,B_2,铁,钙和赖氨酸,并进行动物实验,评价其营养价值。Ⅰ、Ⅱ、Ⅲ组为实验组,Ⅳ组为对照组。实验结果提示第Ⅰ、Ⅱ、Ⅲ组4周后体重分别增重17.5,12.4和10.9g,而对照组体重处于抑制状态,4周后体重呈下降趋势。饲料效价,蛋白质消化率,净利用率,生物价及骨钙含量,铁营养状况均优于对照组。根据实验结果,初步认为江西省粮油研究所研制的强化大米,对于我国以粮谷类为主的膳食结构优化具有重要意义,值得推广。

高甘油三脂血症与胰岛素抵抗及糖代谢异常的关系

探讨高甘油三酯及糖代谢异常之间的关系。方法将７１例高ＴＧ血症患者按照空腹血ＴＧ增高的程度分为高ＴＧⅠ组和Ⅱ组，做葡萄糖耐量和胰岛素释放试验，计算岛素敏感性指数，并以３２例正常血ＴＧ者作对照。采用多因素回     

爱大霉素和庆大霉素对肾皮质线粒体~(45)Ca~(2+)摄取的影响

目的研究爱大霉素和庆大霉素对大鼠肾皮质线粒体钙摄取的影响。方法应用４５Ｃａ２＋示踪技术。结果两药在１ｍｍｏｌ·Ｌ－１时显著促进线粒体钙摄取（分别由每３０ｍｉｎ（１１３．５±７．５）μｍｏｌ·ｇ－１Ｐｒｏ上升到（１４８．０±２４．０）μｍｏｌ·ｇ－１Ｐｒｏ，（１１１．９±１３．０）μｍｏｌ·ｇ－１Ｐｒｏ上升到（１４０．１±１６．６）μｍｏｌ·ｇ－１Ｐｒｏ，Ｐ＜０．０５）；在１０μｍｏｌ·Ｌ－１时显著抑制线粒体钙摄取（分别由每３０ｍｉｎ（１１３．５±７．５）μｍｏｌ·ｇ－１Ｐｒｏ下降到（９２．３±５．７）μｍｏｌ·ｇ－１Ｐｒｏ，（１１１．９±１３．０）μｍｏｌ·ｇ－１Ｐｒｏ下降到（１４０．０±５．３）μｍｏｌ·ｇ－１Ｐｒｏ，Ｐ＜０．０５或Ｐ＜０．０１）。结论两药对线粒体钙摄取的这种双相变化可能与它们肾毒性有关     

血浆复钙与加热法制备ABO定型试剂的实验比较

将血浆转变成血清的方法有复钙和加入轻质高岭土两种,作者把“废血浆”采用56℃加热1 h,以去除纤维蛋白和灭活补体,所得血清与用复钙法制备的血清,在当日、4℃保存2周,-30℃保存2月,进行抗体效价、纤维蛋白原(Fib)含量比较,一共实验了8批,每批结
