LEEP刀治疗与护理相结合治疗宫颈疾病的作用

目的探讨LEEP刀治疗与护理相结合在治疗宫颈疾病中的作用。方法选择应用LEEP刀治疗与红外光治疗两组患者各60例。比较其疗效和护理作用。结果LEEP刀治疗比红外光治疗宫颈疾病效果要好。结论LEEP刀治疗与护理相结合对宫颈疾病的治疗值得推广应用。     

亚硒酸钠对荷Lewis肺癌小鼠癌组织和肝组织溶酶体的作用研究

用差速离心方法分离提取荷Lewis肺癌小鼠癌组织和肝组织富含溶酶体部分,并以溶酶体标志酶酸性磷酸酶(ACP)的游离酶和总酶活性比值作为观察溶酶体膜稳定性变化的指标,观察了亚硒酸钠对两种组织ACP酶活性和膜稳定性的影响。发现硒对癌组织和肝组织ACP活性的异常升高有抑制作用、稳定溶酶体膜,在癌瘤增殖前期作用明显(P<0.05)。提示这种拮抗效应与硒直接和间接的抗脂质过氧化有关。     

Effects of Activated Complement on Lung Fluid Exchange in Conscious Goats:Role of Superoxide Anion

The effects of zymosan-activated plasma(ZAP)on lung fluid exchangeand on superoxide anion production by granulocytes were studied in 8 consciousgoats with chronic lung lymph fistula,It was found that after ZAP infusion, thecirculating granulocytes were activated and the release of superoxide anions wasmarkedly enhanced. There was an increase in lung lymph flow and proteinconcentration.It suggests that the superoxide anion released by the stimulatedgranulocytes can play a role in inducing lung injury by the activated complement.     

血液透析对慢性肾功能衰竭患者血浆心钠素水平的影响

羊踯躅根治疗慢性肾小球肾炎的实验及临床研究

本文用反复静脉注射小剂量牛血清白蛋白复制家兔慢性肾炎,用羊踯躅根治疗。同时,用该药对慢性肾炎病人进行疗效观察。阳性组兔肾小球呈现中至重度颗粒形免疫荧光,肾组织呈明显慢性硬化性肾小球肾炎改变。尿蛋白±～++。治疗组兔及病人治疗后病变及症状均明显减轻或消失。结果提示循环免疫复合物反复沉着可引起兔类似人类的慢性硬化性肾小球肾炎,羊踯躅根对病变有一定的控制和治疗作用,这可能与其抑制免疫发病机制有关。     

番荔枝开花生物学与人工授粉研究

对三年生番荔枝（Ancnona squamosa L.)实生树的开花生物学和人工授粉进行了研究并发现；番荔枝的花有两荔异熟现象，人工授粉能提高座果率，简便而有效的方法是用毛笔直接从树上花药自然裂开的花上聚花粉并立即授在花药没裂开的花上，授粉后两周的座果率达87．9％，授 在花药裂开的花上，座果率为5．3％，与对照照座果率4．4％没有区别，说明花药裂开柱头容受性完全消失，花药裂开时间与品种特有关，目前，广东栽培的番荔枝分为花药早上裂开和傍开两种类型，这两种类型的不同品种之间授粉也能提高座果率，授粉后两周的座果率为83．3％。说明花裂开关12h柱头容受性仍完全正常。

本文采用改良的邻革之酚自氧化法,对51例无遗传性疾病早孕妇女绒毛细胞进行了SOD活力测定。其比活力为426.2±48.4u/mg蛋白(x±SD),测定值范围为217.2～589.1u/mg蛋白,P95>915.0u/mg蛋白。     

"取消中医"严重违背宪法精神

中医药是伟大宝库，新中国成立后“中西医并重共同发展”被写进宪法。有人提出“取消中医”严重违背了宪法精神。中医药工作者要奋发图强，继承创新，提高发展。     

Organization and development of horizontal cells in the goldfish retina, II: Use of monoclonal antibody MH1.

We have produced and characterized a monoclonal antibody, MH1, which selectively labels rod horizontal cells and Müller cells in the goldfish retina. Biochemical and tissue distribution studies indicate that MH1 may recognize four out of five classes of intermediate filament proteins in goldfish: vimentin, desmin, glial fibrillary acidic protein (GFAP), and keratin, but not neurofilament. The intermediate filament which is labeled strongest in the retina is vimentin. In the goldfish retina, the only type of horizontal cells recognized by MH1 appear to be rod horizontal cells. This result suggests that the rod horizontal cell, an interneuron, and Müller (glial) cells share a common antigen: vimentin, which is usually only expressed in mesenchymal origin cells. The development of rod horizontal cells in the goldfish retina was also studied using MH1. The cells were not labeled by MH1 until 4-6 weeks posthatching, a stage in which the animals are already visually active. MH1 also did not label any horizontal cell in the region close to the ora terminalis in the goldfish retina. These results suggest that either the emergence and maturation of rod horizontal cells occur late during goldfish retinal development or the expression of vimentin itself occurs late in the development of rod horizontal cells.
