胆囊炎和胆石症的饮食疗法

胆囊炎、胆石症的发病及复发与饮食密切相关。中医素有“药食同源”之说,《内经》曾有“虚则补之,药以祛之,食以随之”和“谷肉果菜,食养尽之等饮食疗法的论述。饮食疗法简称食疗,首先应遵循食疗原则,主要是注重辨证施食,并辅以药膳。食疗原则胆囊炎、胆石症的食疗目的是注意饮食习惯避免诱发疼痛发作(即胆绞痛),并保证胆囊收缩正常,使胆汁排泄通畅,去除引起胆汁淤滞的因素,抑制胆石的生成。其食疗的基本原则是:1饮食规律忌暴饮暴食。2控制脂肪摄入,适量摄取蛋白质3材料要新鲜,烹调要柔软,口味要清淡。4少吃辛辣品,禁饮酒。5多吃蔬菜、水果,…

双头加压螺纹钉贴股骨距内固定治疗股骨颈骨折

在Ｘ光电视下采用双头加压螺纹钉贴股骨距内固定治疗新鲜股骨颈骨折４２例，随访平均２．５年，其中１６例随访３年以上，骨折愈合率９５．２％，骨折不愈合并股骨头缺血性坏死率４．７６％。认为加压螺纹钉贴股骨距内固定可使钉的受力由较大剪应力变为较大轴向力承受，减少骨折处的剪应力，并加压于骨折端能促进骨折愈合。具有操作简单、进钉准确、创伤小、固定牢靠、并发症少等优点。     

支气管炎非药物疗法功能及形态学观察

我们用组织学,组织化学方法观察支气管炎患者气功前和气功后痰的镜下变化及测量其发声最大值.结果表明:支气管炎患者功后痰内粘多糖的含量、上皮脱落细胞的数量增多,痰中细胞种类增加,如出现浆细胞、肥大细胞、中性粒细胞、淋巴细胞等,体现机体免疫功能提高,机体调节代谢能力增强,从而达到病愈、健体、养心的良效。从功后最大发声值增加,说明肺活量加大,也是患者病情好转的症侯。     

中老年人前列腺体积增长的城乡差异

为了解国人中年以后前列腺的生长情况及其可能的影响因素，对北京、河北、湖北等地四个社区的城乡居民前列腺体积进行了经腹Ｂ超测量。结果表明城区居民的前列腺体积明显大于相应年龄段的农村居民，城区居民的前列腺增长速率比农村居民高二倍。生活环境和饮食习惯的不同可能为其原因之一。     

Electro-oculogram of Retinal Vein Occlusion

Twenty five cases, including 26 eyes with retinal vein occlusion (RVO) were examined by means of the electro-oculogram. The results showed that 23 of the 26 eyes suffering from RVO exhibited abnormalities of the electro-oculogram (EOG). The potential difference and Arden ratio in the RVO eyes were lower than those in the normal eyes (P<0.01). The more the visual acuity of ill eyes was decreased, the higher the abnormal rate of EOG in ill eyes was. 14 eyes had the visual acuity less than 0.1, whose EOGs were abnortmal. Six eyes had the visual acuity from 0. 2 to 0. 4, in which the EOGs of 5 eyes were abnormal. Six eyes had the visual acuity more than 0. 5, a-mong which the EOGs of 4 eyes were abnormal. Based on the above observations, it may be considered that the circulatory disturbance resulting from RVO damages not only the internal layer but also the external layer of the retina. We suggest that EOG is a useful method for distingquishing lesions caused by RVO and may reflect the functional condition     

真皮下血管网岛状皮瓣抗菌力的实验研究

为研究真皮下血管网薄皮瓣用于感染创面的可行性，在家猪臀部两侧分别形成以旋髂深血管主干分支为蒂的传统岛状皮瓣和远侧５０％修薄的真皮下血管网岛状皮瓣。用细菌计数、吖啶橙荧光染色测定白细胞吞噬指数和白细胞内杀菌率，应用激光多普勒、墨汁灌注、透明标本等方法，对两种皮瓣的抗菌力作自身对照研究。结果表明，真皮下血管网岛状皮瓣的抗菌力明显降低，可能与皮瓣修薄后血供减少，白细胞功能相应降低有关。     

REGULATING FUNCTION OF COENZYMIZATION AND DECOENZYMIZATION OF THE LACTATE DEHYDROGENASE ISOZYMES IN THE MOUSE TISSUES DURING HYPOXIA

Objective. To study the characteristics of changes of LDH enzyme patterns of mice under slight hypoxia.Methods. Mice treated with artificial hypoxia, various tissues were made for the test of LDH enzymatic activity by the specific staining technique. LDH (1 -5) relative percentage enzymatic activity (RPEA) were measured with CS-910 dual-wavelength thin layer chromatography scanner.Results. The RPEA of LDH isozymes of various tissues after slight hypoxia shifted to the isozymes LDH1 and LDH2, whose principal subunits are H subunits, and the RPEA of LDH,(H4), LDH2(H3M) increased, while RPEA of LDH5(M4) in various tissues decreased prominently except the cardiac muscle, and that of LDH4(HM3) decreased as well. After polyacrylamide gel electrophoresis (PAGE) of the hypoxia treated cardiac muscle specimen was made, activity subbands originated regularly in the isozyme patterns of LDH, with the regularity of LDH1 (0 subband), LDH2 (0-1 subbands), LDH3 (0-2 subbands), LDH4 (1-3 subbands), LDH5 (2-4 subbands).
