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.     

下眼袋切除术的体会

下眼袋为老年人的下眼睑松垂现象。其原因为下睑皮松驰.皮肤与眼轮匝肌间的纤维组织连接减弱,肌肉及眶隔膜间的张力下降而导致眶隔内脂肪脱垂,使下睑皮肤下垂而形成袋状臃肿,出现老态。切除下眼袋能够起到消除和改善老态纠正异常心理和增强自信的作用。我科从88年开始至91年3月共对98例下眼袋患者施术,最小年龄28岁,最大年龄62岁。其中40—62岁者最多,占78％。女86例男12例。年轻人多有     

烧伤创面切削痂植皮对纠正烧伤后肾脏损害的价值

目的　探讨烧伤合并肾脏损害的治疗方法。方法　对 47例烧伤合并肾损害进行烧伤创面切削痂植皮 ,以减少烧伤毒素、促进创面修复、促进肾脏功能恢复。结果　术后 1周观察 ,3 6例肾损害治愈、9例好转、2例无效 ;完成手术后 ,最快 3d肾损害即可控制。本组最后治愈41例、死亡 6例。结论　对于烧伤合并肾损害 ,及时采用手术治疗 ,不仅利于肾功能的恢复 ,也是保证患者最终康复的重要手段。一旦烧伤病人出现肾功能损害 ,应尽早进行烧伤创面切削痂植皮术修复深度创面。     

慢性肺心病肺部革兰氏阴性杆菌感染

近年来肺部革兰氏阴性杆菌感染的发病率有明显增高的趋势,预后恶劣。我院自1985年8月至1987年5月共收治慢性肺心病及肺部革兰氏阴性杆菌(G-杆菌)感染患者125例,分析报道如下。资料和结果一、一般资科:肺心病的诊断标准均符合第二次全国肺心病会议制定的慢性肺源性心脏病诊断标准。84例肺部G一杆菌感染均符合:(一)有呼吸道感染的临床表现,〔二)X线胸片有肺部或支气管炎症,(三)连续2次或两次以上痰培养为同一G一     

脑梗塞患者红细胞变形能力与红细胞膜微粘度,膜脂质及血浆脂质…

作者检测脑梗塞患者及健康对照组的ＲＢＣ变形能力、ＲＢＣ膜微粘度、膜脂质及血浆脂质后发现，脑梗塞患者ＲＢＣ变形性显著低于对照组，其变形能力与ＲＢＣ膜微粘度、膜胆固醇（Ｃｈ）／磷脂（ＰＬ）比值呈显著负相关，与血浆ＡｐｏＡ－Ⅰ呈显著正相关；ＲＢＣ膜胆固醇与血浆ＡｐｏＡ－Ⅰ及ＨＤＬ－Ｃｈ呈显著负相关，与ＡｐｏＢ呈显著正相关，但与血浆Ｃｈ无相关关系。
